Description of Business [Abstract]
Description of Business	1. Description of Business SG Blocks, Inc. (collectively with its subsidiaries, the “Company,” “we”, “us” or “our”) was previously known as CDSI Holdings, Inc., a Delaware corporation incorporated on December 29, 1993. On November 4, 2011, CDSI Merger Sub, Inc., the Company’s wholly-owned subsidiary, was merged with and into SG Building Blocks, Inc. (“SG Building,” formerly SG Blocks Inc.) (the “Merger”), with SG Building surviving the Merger and becoming a wholly-owned subsidiary of the Company. The Merger was a reverse merger that was accounted for as a recapitalization of SG Building, as SG Building was the accounting acquirer. Accordingly, the historical financial statements presented are the financial statements of SG Building. The building products developed with the Company's proprietary technology and design and engineering expertise are generally stronger, more durable, environmentally sensitive, and erected in less time than traditional construction methods. The use of the SGBlocks building structure typically provides between four to six points towards the Leadership in Energy and Environmental Design (“LEED”) certification levels, including reduced site disturbance, resource reuse, recycled content, innovation in design and use of local and regional materials. Due to the ability of SGBlocks to satisfy such requirements, the Company believes the products produced utilizing its technology and expertise is a leader in environmentally sustainable construction. There are three core product offerings that utilize the Company's The Company also provides engineering and project management services related to the use and modification of Modules in construction. During 2020, the Company formed, SG Echo, LLC, a wholly owned subsidiary of the Company. SG Echo, LLC was formed to complete the business acquisition. The Company acquired substantially all the assets of Echo DCL, a Texas limited liability company, except for Echo's real estate holdings for which the Company obtained a right of first refusal. Echo is a container/modular manufacturer based in Durant, Oklahoma specializing in the design and construction of permanent modular and temporary modular buildings and was one of the Company's key supply chain partners. Echo caters to the military, education, administration facilities, healthcare, government, commercial and residential customers. This acquisition has allowed the Company to expand its reach for the Modules and offer an opportunity to vertically integrate a large portion of the Company's cost of goods sold, as well as increase margins, productivity and efficiency in the areas of design, estimating, manufacturing and delivery and to become the manufacturer of the Company's core container and modular product offerings. T he Company also entered into a joint venture with Clarity Lab Solutions LLC., to provide clinical lab testing related to COVID- 19 As of January 2021 through the fourth quarter of 2021, the Company’s consolidated financial statements include the accounts of Chicago Airport Testing LLC (“CAT”). The Company had a variable interest in CAT as described further below. CAT is in the business of marketing, selling, distributing, leasing and otherwise commercially exploiting certain products and services in the COVID-19 testing and other medical industry. In addition, during 2021, the Company formed SGB Development Corp. (“SG DevCorp”), which is wholly-owned by the Company. SG DevCorp was formed with the purpose of real property development utilizing the Company's technologies. SG DevCorp has a minority interest in Norman Berry II Owners LLC and JDI-Cumberland Inlet LLC as described further below. Reverse Stock Split On February 5, 2020, the Company effected a 1-for-20 As of March 31, 2022, the Company had 12,006,873 shares of common stock issued and outstanding.

Liquidity [Abstract]
Liquidity	2. Liquidity As of March 31, 2022, the Company had cash and cash equivalents of $13,146,418 and a backlog of approximately $7,591,863. See Note 11 2022 Within 1 year $ 7,591,863 Total Backlog $ 7,591,863 The Company has incurred losses since its inception and has negative operating cash flows. Management has taken several actions to ensure that the Company will continue as a going concern. As described below, the Company has recently been able to raise substantial cash through equity offerings. In addition, as further described in these consolidated financial statements, the Company has begun to recognize revenue from new revenue streams. Management believes that these actions will enable the Company to continue as a going concern. The Company completed a public and concurrent private offering in October 2021, which resulted in net proceeds of approximately $10,488,000. See Note 12 The Company believes that it has adequate cash balances to meet obligations coming due in the next twelve The Company does not have any additional sources secured for future funding, and if it is unable to raise the necessary capital at the times it requires such funding, it may need to materially change its business plan, including delaying implementation of aspects of such business plan or curtailing or abandoning such business plan altogether. With the global spread of the ongoing novel coronavirus ("COVID-19") pandemic during 2020, The Company has been impacted by COVID-19 with supply chain distributions, absenteeism by infected workers and skilled labor shortages which has caused delays in projects and the Company could be further impacted if the COVID-19 pandemic continues.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	3. Summary of Significant Accounting Policies Basis of presentation and principals of consolidation – The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to the Current Report on Form 10-Q and Article 8 Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. The condensed financial statements and notes should be read in conjunction with the consolidated financial statements and notes for the year ended December 31, 2021 included in the Company's Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the Securities and Exchange Commission on April 18, 2022. In the opinion of management, all adjustments, consisting of normal accruals, considered necessary for a fair presentation of the interim financial statements have been included. Results for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. Recently adopted accounting pronouncements - New accounting pronouncements implemented by the Company are discussed below or in the related notes, where appropriate. Accounting estimates Operating cycle – The length of the Company’s contracts varies, but is typically between six twelve twelve one year Reclassification – Certain prior year balances were reclassed to conform to current period presentation. Revenue recognition – The Company determines, at contract inception, whether it will transfer control of a promised good or service over time or at a point in time, regardless of the length of contract or other factors. The recognition of revenue aligns with the timing of when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To achieve this core principle, the Company applies the following steps in accordance with its revenue policy: ( 1 Identify the contract with a customer ( 2 Identify the performance obligations in the contract ( 3 Determine the transaction price ( 4 Allocate the transaction price to performance obligations in the contract ( 5 Recognize revenue as performance obligations are satisfied On certain contracts, the Company applies recognition of revenue over time, which is similar to the method the Company applied under previous guidance (i.e. percentage of completion). For product or equipment sales, the Company applies recognition of revenue when the customer obtains control over such goods, which is at a point in time. On October 3, 2019, the Company entered into an Exclusive License Agreement (“ELA” ) pursuant to which it granted an exclusive license for its technology as outlined in the ELA. The ELA is described below. Under the ELA, the Company was to receive royalty payments based upon gross revenues earned by the licensee for commercialized products within the field of design and project management platforms for residential use, including single-family residences and multi-family residences, but excluding military housing. The Company has determined that the ELA granted the licensee a right to access the Company’s intellectual property throughout the license period (or its remaining economic life, if shorter), and thus recognizes revenue over time as the licensee recognized revenue and the Company has the right to payment of royalties. On June 15, 2021, the Company terminated the ELA that was executed on October 3, 2019 which is discussed below. CMC Right of First Refusal Agreement – Agreement CMC Under the Agreement, the Company had a right of first refusal with respect to being engaged as a designer and builder of any real estate projects for which CMC has secured the rights to develop and in which CMC has a greater than fifty percent (50%) interest in the owner or developer entity and has the right to select the builder for such real estate project (the “ROFR Rights”). In exchange for such ROFR Rights, the Company agreed to issue to CMC 2,500 shares of restricted stock of the Company’s common stock, of which 1,250 shares vested on March 31, 2021 and the remaining 1,250 shares was to vest and be issued on September 30, 2021 the event that the Agreement was earlier terminated, CMC was entitled to receive the entire amount of such restricted stock that had vested as of such earlier termination date, but in no event less than 1,250 shares of such restricted stock. The Agreement also provided for customary indemnification and confidentiality obligations between the parties. The 2,500 shares of restricted stock of the Company's common stock has yet to be issued to CMC. The Agreement also provided that CMC has engaged the Company to build and design, in the aggregate, approximately 100 1100 The Company is no longer participating on Ridge Avenue as CMC has decided to proceed with this project as a traditional construction build. The Company previously reported this as a cancellation within the Company's backlog footnote, see Note 11 The Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”) in the fourth quarter of 2020 . Revenue from the activities of the JV is related to clinical testing services and is recognized when services have been rendered, which is at a point in time. Included in the consideration the Company expected to be entitled to receive, the Company estimates its contractual allowances, payer denials and price concessions. In addition, the Company formed Chicago Airport Testing, LLC which collected rental revenue from subleasing to a consortium of government entities assisting in COVID-19 testing. to activities through these two joint ventures, which is included in medical revenue on the accompanying consolidated statements of operations. Disaggregation of Revenues The Company’s revenues are principally derived from construction and engineering contracts related to Modules, and medical revenue derived from lab testing and test kit sales The Company's contracts are with customers in various industries. Revenue recognized at a point in time and recognized over time were The following tables provide further disaggregation of the Company’s Three Months Ended March 31, Revenue by Customer Type 2022 2021 Construction and Engineering Services: $ 39 — % $ 1,085,480 12 % Hotel 897,244 10 % 170,426 2 % Medical - C onstruction — — % 251,560 3 % Multi-Family (includes Single Family) 77,626 1 % 44,746 — % Office 728,875 8 % 177,392 1 % Retail 5,344 1 % 42,015 1 % Special Use 9,642 — % 1,460,045 16 % Subtotal 1,718,770 20 % 3,231,664 35 % Medical Revenue: Medical (lab testing, kit sales and equipment) 6,885,828 80 % 5,955,963 65 % Total revenue by customer type $ 8,604,598 100 % $ 9,187,627 100 % Contract Assets and Contract Liabilities Accounts receivable are recognized in the period when the Company’s right to consideration is unconditional. Accounts receivable are recognized net of an allowance for credit losses. A considerable amount of judgment is required in assessing the likelihood of realization of receivables. The timing of revenue recognition may differ from the timing of invoicing to customers. Contract assets include unbilled amounts from long-term construction services when revenue recognized under the cost-to-cost measure of progress exceeds the amounts invoiced to customers, as the amounts cannot be billed under the terms of our contracts. Such amounts are recoverable from customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. Contract assets are generally classified as current within the condensed consolidated balance sheets. Contract liabilities from construction and engineering contracts occur when amounts invoiced to customers exceed revenues recognized under the cost-to-cost measure of progress. Contract liabilities additionally include advanced payments from customers on certain contracts. Contract liabilities decrease as the Company recognizes revenue from the satisfaction of the related performance obligation. Contract liabilities are generally classified as current within the condensed consolidated balance sheet. A lthough the Company believes it has established adequate procedures for estimating costs to complete on open contracts, it is at least reasonably possible that additional significant costs could occur on contracts prior to completion. The Company periodically evaluates and revises its estimates and makes adjustments when they are considered necessary. Deferred Contract Costs - Prior to entering into the ELA, the Company was subject to an agreement to construct and develop a certain property (“Original Agreement”), which now is subject to the ELA. Upon entering into the ELA, the Company is no longer obliged to its Original Agreement. Upon entering the ELA, the Company had an outstanding accounts receivable balance of $306,143, which was forfeited and recognized this amount as deferred contract costs. This amount was offset by $102,217 , which was reimbursement from the licensee for project costs on this project. The Company incurred total deferred contract costs of $203,926. The Company considered this amount an incremental cost of obtaining that ELA, because the Company expects to recover those costs through future royalty payments. The Company plans to amortize the asset over sixty months , which is the initial term of the ELA because the asset relates to the services transferred to the customer during the contract term. As of . During the three months ended March 31, 2022 and 2021, amortization expense relating to the deferred contract costs amounted to $10,196 and $10,196, respectively, and is included in general and administrative expenses on the accompanying condensed consolidated statement of operations. As previously mentioned, the ELA was terminated on June 15, 2021 but the Company expects to recover the deferred contract costs from the Assignment of Limited Rights Under Membership Interest Redemption Agreement, dated June 15, 2021 as described below. Exclusive License Agreement – On Oc tober 3, 2019, as amen five five In consideration for the License, during the initial term, the Licensee agreed to pay the Company a royalty of (x) five percent (5%) on the first $20,000,000 of gross revenues derived from the Licensee’s commercialization of the License (net of customary discounts, sales taxes, delivery charges, and amounts for returns) (the “Gross Revenues”), (y) four and one-half percent (4.5%) on the next $30,000,000 of Gross Revenues, and (z) five percent (5%) on all Gross Revenues thereafter (collectively, the “Royalty”), The ELA provided for customary indemnification obligations between the parties and further provides that the Licensee will indemnify the Company for any claims arising out of the commercialization of the License by the Licensee or any of its subsidiaries, contractors, or sublicensees. On June 15, 2021, the Company terminated the ELA. In connection with the termination, the Company entered into a Settlement and Mutual Release Agreement (the “Settlement Agreement”) with CPF, the general partner (the “Licensee”) of CPF MF 2019-1 LLC (“CPF MF”), and Capital Plus Financial, LLC, a limited partner of the Licensee (“Capital Plus”) and an Assignment of Limited Rights Under Membership Interest Redemption Agreement, dated June 15, 2021, with Capital Plus and the Licensee. Pursuant to the Settlement Agreement with CPF and Capital Plus, the ELA was terminated, the Company released CPF and CPF MF for any claims in exchange for releases from CPF and Capital Plus and the Company received an assignment of right under certain circumstances to a $1.25 million redemption distribution from CPF MF under its Operating Agreement. Bu - The Company accounts for business acquisitions using the acquisition method of accounting in accordance with ASC 805 Variable Interest Entities – The Company accounts for certain legal entities as variable interest entities (“VIE"). When evaluating a VIE for consolidation, the Company must determine whether or not there is a variable interest in the entity. Variable interests are investments or other interests that absorb portions of an entity’s expected losses or receive portions of the entity’s expected returns. If it is determined that the Company does not have a variable interest in the VIE, no further analysis is required and the VIE is not consolidated. If the Company holds a variable interest in a VIE, the Company consolidates the VIE when there is a controlling financial interest in the VIE and therefore are deemed to be the primary beneficiary. The Company is determined to have a controlling financial interest in a VIE when it has both the power to direct the activities of the VIE that most significantly impact the VIE economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to that VIE. This determination is evaluated periodically as facts and circumstances change. On August 27, 2020 the Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”). In consideration and subject to Clarity Lab’s services and commitments and provided the agreement remains valid and in force, and is not terminated, the Company agreed to issue 200,000 restricted shares of SGB common stock over a defined vesting period starting in December 1, 2020.

Investment Entities – On May 31, 2021, the Company's subsidiary SG DevCorp agreed to contribute $600,000 to acquire a 50% membership interest in Norman Berry II Owner LLC. The Company contributed $350,329 and $114,433 of the initial $600,000 in the second quarter and third quarter of 2021 respectively, with the remaining $135,238 The Company will use the equity method to report the activities as an investment in its consolidated financial statements.

The Company has determined it is not the primary beneficiary of JDI-Cumberland Inlet, LLC and thus will not consolidate the activities in its consolidated financial statements. The Company will use the equity method to report the activities as an investment in its consolidated financial statements. On February 24, 2022 the Company made a $500,000 capital investment for a 1.2% ownership in Moliving, a nomadic hospitality solution company. Cash and cash equivalents – The Company considers cash and cash equivalents to include all short-term, highly liquid investments that are readily convertible to known amounts of cash and have original maturities of three months or less upon acquisition. Cash and cash equivalents totaled $ 13,146,418 and $ as of March 31, 2022 Short-term investment – The Company classifies investments consisting of a certificate of deposit with a maturity greater than three months but less than one year as short-term investment. The Company had no short-term investment as of March 31, 2022 or 2021, respectively. Accounts receivable and allowance for credit losses – Accounts receivable are receivables generated from sales to customers and progress billings on performance type contracts. Amounts included in accounts receivable are deemed to be collectible within the Company’s operating cycle. The Company recognizes accounts receivable at invoiced amounts. The allowance for credit losses reflects the Company's best estimate of expected losses inherent in the accounts receivable balances. Management provides an allowance for credit losses based on the Company’s historical losses, specific customer circumstances, and general economic conditions. Periodically, management reviews accounts receivable and adjusts the allowance based on current circumstances and charges off uncollectible receivables when all attempts to collect have been exhausted and the prospects for recovery are remote. Recoveries are recognized when they are received. Actual collection losses may differ from our estimates and could be material to our consolidated financial position, results of operations, and cash flows. Inventory – Raw construction materials (primarily shipping containers and fabrication materials) are valued at the lower of cost (first-in, first-out method) or net realizable value. Finished goods and work-in-process inventories are valued at the lower of cost or net realizable value, using the specific identification method. Medical equipment and COVID-19 test and testing supplies are valued at the lower of cost, (first-in, first-out method) or net realizable value. As of March 31, 2022 there was inventory of As of December 31, 2021 there was inventory of $516,731 for construction materials, and $757,094 of medical equipment and COVID-19 test and testing supplies. Goodwill – The Company performs its impairment test of goodwill at the reporting unit level each fiscal year, or more frequently if events or circumstances change that would more likely tha n not reduce the fair value of its reporting unit below its carrying values. The Company performs a goodwill impairment test by comparing the fair value of the reporting unit with its carrying value and recognizes an impairment charge for the amount by which the carrying value exceeds the fair value, not to exceed the total amount of goodwill . The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. Intangible assets – Intangible assets consist of $ 2,766,000 97,164 The amortization expense For the year ending December 31,: 2022 $ 121,147 2023 161,176 2024 160,469 2025 157,052 2026 139,716 Thereafter 1,313,850 $ 2,053,410 Property, plant and equipment – Property, plant and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated lives of each asset. Estimated useful lives for significant classes of assets are as follows: computer and software 3 to 5 years, furniture and other equipment 5 to 7 years, automobiles 2 to 5 years, buildings held for lease 5 to 7 years, and equipment o 29 Held For Sale Assets Convertible instruments – The Company bifurcates conversion options from their host instruments and accounts for them as free standing derivative financial instruments according to certain criteria. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument. Common stock purchase warrants and other derivative financial instruments – The Company classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) provides a choice of net-cash settlement or settlement in the Company’s own shares (physical settlement or net-share settlement) providing that such contracts are indexed to the Company’s own stock. The Company classifies as assets or liabilities any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if any event occurs and if that event is outside the Company’s control) or (ii) gives the counterparty a choice of net-cash settlement or settlement shares (physical settlement or net-cash settlement). The Company assesses classification of common stock purchase warrants and other free standing derivatives at each reporting date to determine whether a change in classification between assets and liabilities or equity is required. Fair value measurements – Financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities are carried at cost, which the Company believes approximates fair value due to the short-term nature of these instruments. The Company measures the fair value of financial assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The Company uses three levels of inputs that may be used to measure fair value: Level 1 Quoted prices in active markets for identical assets or liabilities. Level 2 Quoted prices for similar assets and liabilities in active markets or inputs that are observable. Level 3 Inputs that are unobservable (for example, cash flow modeling inputs based on assumptions). Transfer into and transfers out of the hierarchy levels are recognized as if they had taken place at the end of the reporting period. Share-based payments – The Company measures the cost of services received in exchange for an award of equity instruments based on the fair value of the award. For employees and directors, including non-employee directors, the fair value of a stock option award is measured on the grant date. The fair value amount is then recognized over the period services are required to be provided in exchange for the award, usually the vesting period. The Company recognizes stock-based compensation expense on a graded-vesting basis over the requisite service period for each separately vesting tranche of each award. Stock-based compensation expense to employees and all directors are reported within payroll and related expenses in the consolidated statements of operations. Stock-based compensation expense to non-employees is reported within marketing and business development expense in the condensed consolidated statements of operations. Income taxes The Company accounts for income taxes utilizing the asset and liability approach. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for anticipated tax audit issues based on the Company’s estimate of whether, and the extent to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the liabilities are no longer determined to be necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result. Concentrations of credit risk – Financial instruments, that potentially subject the Company to concentration of credit risk, consist principally of cash and cash equivalents. The Company places its cash with high credit quality institutions. At times, such amounts may be in excess of the FDIC insurance limits. The Company has not experienced any losses in such account and believes that it is not exposed to any significant credit risk on the account. With respect to receivables, concentrations of credit risk are limited to a few customers in the construction industry. The Company performs ongoing credit evaluations of its customers’ financial condition and, generally, requires no collateral from its customers other than normal lien rights. At March 31, 2022 and December 31, 2021, 75% and 78%, respectively, of the Company’s gross accounts receivable were due from two Revenue relating to two and two customers represented approximately 90% and 80% of the Company's total revenue for the three months ended March 31, 2022 and 2021, respectively. Cost of revenue relating to two and two vendors represented approximately 28% and 28% of the Company’s total cost of revenue for the three months ended March 31, 2022 and 2021, respectively. The Company believes it has access to alternative suppliers, with limited disruption to the business, should circumstances change with its existing suppliers.

Net Income (Loss) Per Share [Abstract]
Net Income (Loss) Per Share	10. Net Income (Loss) Per Share Basic net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of the common shares issuable upon the exercise of stock options and warrants. Potentially dilutive common shares are excluded from the calculation if their effect is antidilutive. At March 31, 2022, there were restricted stock units, options and warrants of outstanding that could potentially dilute future net income per share . Because the Company had a net loss as of March 31, 2022, it is prohibited from including potential common shares in the computation of diluted per share amounts. Accordingly, the Company has used the same number of shares outstanding to calculate both the basic and diluted loss per share. March 31, 2021 , including options to non-employees and non-directors, restricted stock units and warrants to purchase 36,436, 884,343 and 128,090 shares of common stock, respectively, outstanding that could potentially dilute future net income per share.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	16. Commitm Legal Proceedings The Company is subject to certain claims and lawsuits arising in the normal course of business. The Company assesses liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that the Company will incur a loss and the amount of the loss can be reasonably estimated, the Company records a liability in our consolidated financial statements. These legal accruals may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of the loss is not estimable, the Company does not record an accrual, consistent with applicable accounting guidance. Based on information currently available, advice of counsel, and available insurance coverage, the Company believes that the established accruals are adequate and the liabilities arising from the legal proceedings will not have a material adverse effect on the consolidated financial condition. However, that in light of the inherent uncertainty in legal proceedings there can be no assurance that the ultimate resolution of a matter will not exceed established accruals. As a result, the outcome of a particular matter or a combination of matters may be material to the results of operations for a particular period, depending upon the size of the loss or the income for that particular period. 1.) Pizzarotti Litigation Pizzarotti’s suit arose from a contract dated April 3, 2018 that it executed with Phipps whereby Pizzarotti, a construction manager, engaged Phipps to perform stone procuring and tile work at a construction project located at 161 Maiden Lane, New York 10038. Pizzarotti’s claims against the Company arise from a purported assignment agreement dated August 10, 2018, whereby Pizzarotti claims that the Company agreed to assume certain obligations of Phipps under a certain trade contract between Pizzarotti and Phipps & Co. Phipps’ claims against the Company arise from a purported Assignment Agreement, dated as of May 30, 2018, between Pizzarotti, Phipps and the Company (the “Assignment Agreement”), pursuant to which, it is alleged, that the Company agreed to provide a letter of credit in connection with the sub-contracted work to be provided by Phipps to Pizzarotti. The Company believes that the Assignment Agreement was void for lack of consideration and moved to dismiss the case on those and other grounds. On June 17, 2020, the New York Supreme Court entered an order dismissing certain claims against the Company brought by cross claimant Phipps & Co. Specifically, the court dismissed Phipps’ claims for indemnification, contribution, fraud, negligence and negligent misrepresentation. The court did not dismiss Phipps’ claim for breach of the Assignment Agreement. The issue of the validity of the Assignment Agreement, and the Company’s defenses to the claims brought by the plaintiff Pizzarotti, and cross claimant Phipps, are being litigated. The Company maintains that the Assignment Agreement, to the extent valid and enforceable, was properly terminated and/or there are no damages, and, consequently, that the claims brought against the Company are without merit. The Company intends to continue to vigorously defend the litigation. The parties have engaged in written discovery but no depositions have been conducted as of yet. By motion dated February 24, 2021, Pizzarotti moved to stay the entire action pending the outcome of a separate litigation captioned Pizzarotti, LLC v. FPG Maiden Lane, LLC et. al Litigation is subject to many uncertainties, and the outcome of this action is not predicted with assurance. The Company is currently unable to predict the possible loss or range of loss, if any, associated with the resolution of this litigation, and, accordingly, the Company has made no provision related to this matter in the consolidated financial statements. 2.)

The Company has filed an answer to the ICON complaint denying the allegations and raised eleven affirmative defenses and that it is entitled to indemnification and/or contribution from Echo DCL and its principal Michael Ames. The parties are currently engaged in discovery. Litigation is subject to many uncertainties, and the outcome of this action is not predicted with assurance. The Company is currently unable to predict the possible loss or range of loss, if any, associated with the resolution of this litigation, and, accordingly, the Company has made no provision related to this matter in the consolidated financial statements.

Operating cycle	Operating cycle – The length of the Company’s contracts varies, but is typically between six twelve twelve one year
Reclassification	Reclassification – Certain prior year balances were reclassed to conform to current period presentation.
Revenue recognition	Revenue recognition – The Company determines, at contract inception, whether it will transfer control of a promised good or service over time or at a point in time, regardless of the length of contract or other factors. The recognition of revenue aligns with the timing of when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To achieve this core principle, the Company applies the following steps in accordance with its revenue policy: ( 1 Identify the contract with a customer ( 2 Identify the performance obligations in the contract ( 3 Determine the transaction price ( 4 Allocate the transaction price to performance obligations in the contract ( 5 Recognize revenue as performance obligations are satisfied On certain contracts, the Company applies recognition of revenue over time, which is similar to the method the Company applied under previous guidance (i.e. percentage of completion). For product or equipment sales, the Company applies recognition of revenue when the customer obtains control over such goods, which is at a point in time. On October 3, 2019, the Company entered into an Exclusive License Agreement (“ELA” ) pursuant to which it granted an exclusive license for its technology as outlined in the ELA. The ELA is described below. Under the ELA, the Company was to receive royalty payments based upon gross revenues earned by the licensee for commercialized products within the field of design and project management platforms for residential use, including single-family residences and multi-family residences, but excluding military housing. The Company has determined that the ELA granted the licensee a right to access the Company’s intellectual property throughout the license period (or its remaining economic life, if shorter), and thus recognizes revenue over time as the licensee recognized revenue and the Company has the right to payment of royalties. On June 15, 2021, the Company terminated the ELA that was executed on October 3, 2019 which is discussed below. CMC Right of First Refusal Agreement – Agreement CMC Under the Agreement, the Company had a right of first refusal with respect to being engaged as a designer and builder of any real estate projects for which CMC has secured the rights to develop and in which CMC has a greater than fifty percent (50%) interest in the owner or developer entity and has the right to select the builder for such real estate project (the “ROFR Rights”). In exchange for such ROFR Rights, the Company agreed to issue to CMC 2,500 shares of restricted stock of the Company’s common stock, of which 1,250 shares vested on March 31, 2021 and the remaining 1,250 shares was to vest and be issued on September 30, 2021 the event that the Agreement was earlier terminated, CMC was entitled to receive the entire amount of such restricted stock that had vested as of such earlier termination date, but in no event less than 1,250 shares of such restricted stock. The Agreement also provided for customary indemnification and confidentiality obligations between the parties. The 2,500 shares of restricted stock of the Company's common stock has yet to be issued to CMC. The Agreement also provided that CMC has engaged the Company to build and design, in the aggregate, approximately 100 1100 The Company is no longer participating on Ridge Avenue as CMC has decided to proceed with this project as a traditional construction build. The Company previously reported this as a cancellation within the Company's backlog footnote, see Note 11 The Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”) in the fourth quarter of 2020 . Revenue from the activities of the JV is related to clinical testing services and is recognized when services have been rendered, which is at a point in time. Included in the consideration the Company expected to be entitled to receive, the Company estimates its contractual allowances, payer denials and price concessions. In addition, the Company formed Chicago Airport Testing, LLC which collected rental revenue from subleasing to a consortium of government entities assisting in COVID-19 testing. to activities through these two joint ventures, which is included in medical revenue on the accompanying consolidated statements of operations. Disaggregation of Revenues The Company’s revenues are principally derived from construction and engineering contracts related to Modules, and medical revenue derived from lab testing and test kit sales The Company's contracts are with customers in various industries. Revenue recognized at a point in time and recognized over time were The following tables provide further disaggregation of the Company’s Three Months Ended March 31, Revenue by Customer Type 2022 2021 Construction and Engineering Services: $ 39 — % $ 1,085,480 12 % Hotel 897,244 10 % 170,426 2 % Medical - C onstruction — — % 251,560 3 % Multi-Family (includes Single Family) 77,626 1 % 44,746 — % Office 728,875 8 % 177,392 1 % Retail 5,344 1 % 42,015 1 % Special Use 9,642 — % 1,460,045 16 % Subtotal 1,718,770 20 % 3,231,664 35 % Medical Revenue: Medical (lab testing, kit sales and equipment) 6,885,828 80 % 5,955,963 65 % Total revenue by customer type $ 8,604,598 100 % $ 9,187,627 100 % Contract Assets and Contract Liabilities Accounts receivable are recognized in the period when the Company’s right to consideration is unconditional. Accounts receivable are recognized net of an allowance for credit losses. A considerable amount of judgment is required in assessing the likelihood of realization of receivables. The timing of revenue recognition may differ from the timing of invoicing to customers. Contract assets include unbilled amounts from long-term construction services when revenue recognized under the cost-to-cost measure of progress exceeds the amounts invoiced to customers, as the amounts cannot be billed under the terms of our contracts. Such amounts are recoverable from customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. Contract assets are generally classified as current within the condensed consolidated balance sheets. Contract liabilities from construction and engineering contracts occur when amounts invoiced to customers exceed revenues recognized under the cost-to-cost measure of progress. Contract liabilities additionally include advanced payments from customers on certain contracts. Contract liabilities decrease as the Company recognizes revenue from the satisfaction of the related performance obligation. Contract liabilities are generally classified as current within the condensed consolidated balance sheet. A lthough the Company believes it has established adequate procedures for estimating costs to complete on open contracts, it is at least reasonably possible that additional significant costs could occur on contracts prior to completion. The Company periodically evaluates and revises its estimates and makes adjustments when they are considered necessary. Deferred Contract Costs - Prior to entering into the ELA, the Company was subject to an agreement to construct and develop a certain property (“Original Agreement”), which now is subject to the ELA. Upon entering into the ELA, the Company is no longer obliged to its Original Agreement. Upon entering the ELA, the Company had an outstanding accounts receivable balance of $306,143, which was forfeited and recognized this amount as deferred contract costs. This amount was offset by $102,217 , which was reimbursement from the licensee for project costs on this project. The Company incurred total deferred contract costs of $203,926. The Company considered this amount an incremental cost of obtaining that ELA, because the Company expects to recover those costs through future royalty payments. The Company plans to amortize the asset over sixty months , which is the initial term of the ELA because the asset relates to the services transferred to the customer during the contract term. As of . During the three months ended March 31, 2022 and 2021, amortization expense relating to the deferred contract costs amounted to $10,196 and $10,196, respectively, and is included in general and administrative expenses on the accompanying condensed consolidated statement of operations. As previously mentioned, the ELA was terminated on June 15, 2021 but the Company expects to recover the deferred contract costs from the Assignment of Limited Rights Under Membership Interest Redemption Agreement, dated June 15, 2021 as described below. Exclusive License Agreement – On Oc tober 3, 2019, as amen five five In consideration for the License, during the initial term, the Licensee agreed to pay the Company a royalty of (x) five percent (5%) on the first $20,000,000 of gross revenues derived from the Licensee’s commercialization of the License (net of customary discounts, sales taxes, delivery charges, and amounts for returns) (the “Gross Revenues”), (y) four and one-half percent (4.5%) on the next $30,000,000 of Gross Revenues, and (z) five percent (5%) on all Gross Revenues thereafter (collectively, the “Royalty”), The ELA provided for customary indemnification obligations between the parties and further provides that the Licensee will indemnify the Company for any claims arising out of the commercialization of the License by the Licensee or any of its subsidiaries, contractors, or sublicensees. On June 15, 2021, the Company terminated the ELA. In connection with the termination, the Company entered into a Settlement and Mutual Release Agreement (the “Settlement Agreement”) with CPF, the general partner (the “Licensee”) of CPF MF 2019-1 LLC (“CPF MF”), and Capital Plus Financial, LLC, a limited partner of the Licensee (“Capital Plus”) and an Assignment of Limited Rights Under Membership Interest Redemption Agreement, dated June 15, 2021, with Capital Plus and the Licensee. Pursuant to the Settlement Agreement with CPF and Capital Plus, the ELA was terminated, the Company released CPF and CPF MF for any claims in exchange for releases from CPF and Capital Plus and the Company received an assignment of right under certain circumstances to a $1.25 million redemption distribution from CPF MF under its Operating Agreement.
Business Combinations	Bu - The Company accounts for business acquisitions using the acquisition method of accounting in accordance with ASC 805
Variable Interest Entities	Variable Interest Entities – The Company accounts for certain legal entities as variable interest entities (“VIE"). When evaluating a VIE for consolidation, the Company must determine whether or not there is a variable interest in the entity. Variable interests are investments or other interests that absorb portions of an entity’s expected losses or receive portions of the entity’s expected returns. If it is determined that the Company does not have a variable interest in the VIE, no further analysis is required and the VIE is not consolidated. If the Company holds a variable interest in a VIE, the Company consolidates the VIE when there is a controlling financial interest in the VIE and therefore are deemed to be the primary beneficiary. The Company is determined to have a controlling financial interest in a VIE when it has both the power to direct the activities of the VIE that most significantly impact the VIE economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to that VIE. This determination is evaluated periodically as facts and circumstances change. On August 27, 2020 the Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”). In consideration and subject to Clarity Lab’s services and commitments and provided the agreement remains valid and in force, and is not terminated, the Company agreed to issue 200,000 restricted shares of SGB common stock over a defined vesting period starting in December 1, 2020. The restricted shares of SGB common stock were not issued to Clarity Labs as certain capital commitments were not met. As of December 31, 2021, $502,958 was due to Clarity Labs for expenses paid on behalf of Clarity Mobile Venture, and is included in Due to Affiliates, year ended December 31, 2021 The Company has determined it is the primary beneficiary of Clarity Mobile Venture and has thus consolidated the activities in its consolidated financial statements. On January 18, 2021 the Company entered into an operating agreement to form CAT. The purpose of CAT was to market , sell, distribute, lease and otherwise commercially exploit certain products and services in the COVID- 19 The Company has determined it is the primary beneficiary of CAT and has thus consolidated the activities in its consolidated financial statements.
Investment Entities	Investment Entities – On May 31, 2021, the Company's subsidiary SG DevCorp agreed to contribute $600,000 to acquire a 50% membership interest in Norman Berry II Owner LLC. The Company contributed $350,329 and $114,433 of the initial $600,000 in the second quarter and third quarter of 2021 respectively, with the remaining $135,238 The Company will use the equity method to report the activities as an investment in its consolidated financial statements. On June 24, 2021, the Company's subsidiary, SG DevCorp, entered into an operating agreement with Jacoby Development for a 10% non-dilutable equity interest for JDI-Cumberland Inlet, LLC. The Company contributed $3,000,000 for its 10% equity interest. The purpose of JDI-Cumberland Inlet, LLC is to develop a waterfront parcel in a mixed-use destination community. The Company has determined it is not the primary beneficiary of JDI-Cumberland Inlet, LLC and thus will not consolidate the activities in its consolidated financial statements. The Company will use the equity method to report the activities as an investment in its consolidated financial statements. On February 24, 2022 the Company made a $500,000 capital investment for a 1.2% ownership in Moliving, a nomadic hospitality solution company.
Cash and cash equivalents	Cash and cash equivalents – The Company considers cash and cash equivalents to include all short-term, highly liquid investments that are readily convertible to known amounts of cash and have original maturities of three months or less upon acquisition. Cash and cash equivalents totaled $ 13,146,418 and $ as of March 31, 2022
Short-term investment	Short-term investment – The Company classifies investments consisting of a certificate of deposit with a maturity greater than three months but less than one year as short-term investment. The Company had no short-term investment as of March 31, 2022 or 2021, respectively.
Accounts receivable and allowance for credit losses	Accounts receivable and allowance for credit losses – Accounts receivable are receivables generated from sales to customers and progress billings on performance type contracts. Amounts included in accounts receivable are deemed to be collectible within the Company’s operating cycle. The Company recognizes accounts receivable at invoiced amounts. The allowance for credit losses reflects the Company's best estimate of expected losses inherent in the accounts receivable balances. Management provides an allowance for credit losses based on the Company’s historical losses, specific customer circumstances, and general economic conditions. Periodically, management reviews accounts receivable and adjusts the allowance based on current circumstances and charges off uncollectible receivables when all attempts to collect have been exhausted and the prospects for recovery are remote. Recoveries are recognized when they are received. Actual collection losses may differ from our estimates and could be material to our consolidated financial position, results of operations, and cash flows.
Inventory	Inventory – Raw construction materials (primarily shipping containers and fabrication materials) are valued at the lower of cost (first-in, first-out method) or net realizable value. Finished goods and work-in-process inventories are valued at the lower of cost or net realizable value, using the specific identification method. Medical equipment and COVID-19 test and testing supplies are valued at the lower of cost, (first-in, first-out method) or net realizable value. As of March 31, 2022 there was inventory of As of December 31, 2021 there was inventory of $516,731 for construction materials, and $757,094 of medical equipment and COVID-19 test and testing supplies.
Goodwill	Goodwill – The Company performs its impairment test of goodwill at the reporting unit level each fiscal year, or more frequently if events or circumstances change that would more likely tha n not reduce the fair value of its reporting unit below its carrying values. The Company performs a goodwill impairment test by comparing the fair value of the reporting unit with its carrying value and recognizes an impairment charge for the amount by which the carrying value exceeds the fair value, not to exceed the total amount of goodwill . The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss.
Intangible assets	Intangible assets – Intangible assets consist of $ 2,766,000 97,164 The amortization expense For the year ending December 31,: 2022 $ 121,147 2023 161,176 2024 160,469 2025 157,052 2026 139,716 Thereafter 1,313,850 $ 2,053,410
Property, plant and equipment	Property, plant and equipment – Property, plant and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated lives of each asset. Estimated useful lives for significant classes of assets are as follows: computer and software 3 to 5 years, furniture and other equipment 5 to 7 years, automobiles 2 to 5 years, buildings held for lease 5 to 7 years, and equipment o 29
Held For Sale Assets	Held For Sale Assets
Convertible instruments	Convertible instruments – The Company bifurcates conversion options from their host instruments and accounts for them as free standing derivative financial instruments according to certain criteria. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument.
Common stock purchase warrants and other derivative financial instruments	Common stock purchase warrants and other derivative financial instruments – The Company classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) provides a choice of net-cash settlement or settlement in the Company’s own shares (physical settlement or net-share settlement) providing that such contracts are indexed to the Company’s own stock. The Company classifies as assets or liabilities any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if any event occurs and if that event is outside the Company’s control) or (ii) gives the counterparty a choice of net-cash settlement or settlement shares (physical settlement or net-cash settlement). The Company assesses classification of common stock purchase warrants and other free standing derivatives at each reporting date to determine whether a change in classification between assets and liabilities or equity is required.
Fair value measurements	Fair value measurements – Financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities are carried at cost, which the Company believes approximates fair value due to the short-term nature of these instruments. The Company measures the fair value of financial assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The Company uses three levels of inputs that may be used to measure fair value: Level 1 Quoted prices in active markets for identical assets or liabilities. Level 2 Quoted prices for similar assets and liabilities in active markets or inputs that are observable. Level 3 Inputs that are unobservable (for example, cash flow modeling inputs based on assumptions). Transfer into and transfers out of the hierarchy levels are recognized as if they had taken place at the end of the reporting period.
Share-based payments	Share-based payments – The Company measures the cost of services received in exchange for an award of equity instruments based on the fair value of the award. For employees and directors, including non-employee directors, the fair value of a stock option award is measured on the grant date. The fair value amount is then recognized over the period services are required to be provided in exchange for the award, usually the vesting period. The Company recognizes stock-based compensation expense on a graded-vesting basis over the requisite service period for each separately vesting tranche of each award. Stock-based compensation expense to employees and all directors are reported within payroll and related expenses in the consolidated statements of operations. Stock-based compensation expense to non-employees is reported within marketing and business development expense in the condensed consolidated statements of operations.
Income taxes	Income taxes The Company accounts for income taxes utilizing the asset and liability approach. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for anticipated tax audit issues based on the Company’s estimate of whether, and the extent to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the liabilities are no longer determined to be necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.
Concentrations of credit risk	Concentrations of credit risk – Financial instruments, that potentially subject the Company to concentration of credit risk, consist principally of cash and cash equivalents. The Company places its cash with high credit quality institutions. At times, such amounts may be in excess of the FDIC insurance limits. The Company has not experienced any losses in such account and believes that it is not exposed to any significant credit risk on the account. With respect to receivables, concentrations of credit risk are limited to a few customers in the construction industry. The Company performs ongoing credit evaluations of its customers’ financial condition and, generally, requires no collateral from its customers other than normal lien rights. At March 31, 2022 and December 31, 2021, 75% and 78%, respectively, of the Company’s gross accounts receivable were due from two Revenue relating to two and two customers represented approximately 90% and 80% of the Company's total revenue for the three months ended March 31, 2022 and 2021, respectively. Cost of revenue relating to two and two vendors represented approximately 28% and 28% of the Company’s total cost of revenue for the three months ended March 31, 2022 and 2021, respectively. The Company believes it has access to alternative suppliers, with limited disruption to the business, should circumstances change with its existing suppliers.
