Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue Remaining Performance Obligations We had $542.7 million of remaining performance obligations yet to be satisfied as of March 31, 2023. We expect to recognize $432.7 million of our remaining performance obligations as revenue within the next twelve months. Contract Balances Contract terms with customers include the timing of billing and payments, which usually differs from the timing of revenue recognition. As a result, we carry contract assets and liabilities in our balance sheet. These contract assets and liabilities are calculated on a contract-by-contract basis and are classified as current. We present our contract assets in the balance sheet as Costs and Estimated Earnings in Excess of Billings on Uncompleted Contracts ("CIE"). CIE consists of revenue recognized in excess of billings. We present our contract liabilities in the balance sheet as Billings on Uncompleted Contracts in Excess of Costs and Estimated Earnings ("BIE"). BIE consists of billings in excess of revenue recognized. The following table provides information about CIE and BIE: March 31, June 30, Change (in thousands) Costs and estimated earnings in excess of billings on uncompleted contracts $ 53,398 $ 44,752 $ 8,646 Billings on uncompleted contracts in excess of costs and estimated earnings (114,729) (65,106) (49,623) Net contract liabilities $ (61,331) $ (20,354) $ (40,977) The difference between the beginning and ending balances of our CIE and BIE primarily results from the timing of revenue recognized relative to the billings on the associated contract. The amount of revenue recognized during the nine months ended March 31, 2023 that was included in the June 30, 2022 BIE balance was $57.0 million. This revenue consists primarily of work performed during the period on contracts with customers that had advance billings. Progress billings in accounts receivable at March 31, 2023 and June 30, 2022 included retentions to be collected within one year of $18.9 million and $16.1 million, respectively. Contract retentions collectible beyond one year are included in other assets, non-current in the Condensed Consolidated Balance Sheets and totaled $7.8 million as of March 31, 2023 and $4.0 million as of June 30, 2022. Disaggregated Revenue Revenue disaggregated by reportable segment is presented in Note 9 - Segment Information. The following tables presents revenue disaggregated by geographic area where the work was performed and by contract type: Geographic Disaggregation: Three Months Ended Nine Months Ended March 31, March 31, March 31, March 31, (In thousands) United States $ 178,261 $ 160,453 $ 524,731 $ 459,654 Canada 6,932 16,268 52,742 45,038 Other international 1,702 282 11,693 2,369 Total Revenue $ 186,895 $ 177,003 $ 589,166 $ 507,061 Contract Type Disaggregation: Three Months Ended Nine Months Ended March 31, March 31, March 31, March 31, (In thousands) Fixed-price contracts $ 96,755 $ 100,602 $ 311,511 $ 303,508 Time and materials and other cost reimbursable contracts 90,140 76,401 277,655 203,553 Total Revenue $ 186,895 $ 177,003 $ 589,166 $ 507,061 Typically, we assume more risk with fixed-price contracts since increases in costs to perform the work may not be recoverable. However, these types of contracts typically offer higher profits than time and materials and other cost reimbursable contracts when completed at or below the costs originally estimated. The profitability of time and materials and other cost reimbursable contracts is typically lower than fixed-price contracts and is usually less volatile than fixed-price contracts since the profit component is factored into the rates charged for labor, equipment and materials, or is expressed in the contract as a percentage of the reimbursable costs incurred. Revisions in Estimates During the third quarter of fiscal 2023, unfavorable changes in the estimated recovery of change orders and increased forecasted costs to complete certain midstream gas processing capital projects in the Process and Industrial Facilities segment resulted in the projects reducing gross profit by $3.3 million. Together with prior unfavorable changes in the estimated recovery of change orders and increased costs, the projects reduced gross profit by $12.7 million during the nine months ended March 31, 2023. These charges were primarily the result of the client not approving adequate compensation to us for the impact that excessive scope changes had on our ability to progress work on the project according to forecast and for the impact that global supply chain issues and inflation had on the projects. We have accrued the full expected loss for these projects, which we expect to be mechanically complete in July 2023. During the three and nine months ended March 31, 2022, our results of operations were materially impacted by an increase in the forecasted costs to complete a midstream gas processing project in the Process and Industrial Facilities segment, which resulted in a decrease in gross profit of $4.8 million. The increase in forecasted costs was primarily due to performance of a now-terminated subcontractor, which required rework in order to meet our client's expectations. During fiscal 2022, our results of operations were materially impacted by changes in the forecasted costs to complete a large capital project in the Utility and Power Infrastructure segment. Improved project execution resulted in an increase in gross profit of $0.8 million during the three months ended March 31, 2022. However, increases in the forecasted costs to complete the project during the first half of fiscal 2022 resulted in the project reducing gross profit by $5.1 million during the nine months ended March 31, 2022. The increase in forecasted costs during the first half of the fiscal year was principally due to unexpected equipment repairs during commissioning that delayed the scheduled completion and increased the estimated costs to complete. The project was completed in fiscal 2022. During fiscal 2022, our results of operations were materially impacted by an increase in the costs required to complete a thermal energy storage tank repair and maintenance project in the Storage and Terminal Solutions segment, which resulted in a decrease in gross profit of $5.5 million in the first half of fiscal 2022. The increase in costs was primarily due to changes in repair scope, expanded client weld testing and associated schedule delays. We completed these repairs in the first quarter of fiscal 2023.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets Including Goodwill	Goodwill and Other Intangible Assets Goodwill The changes in the carrying value of goodwill by segment are as follows: Utility and Power Infrastructure Process and Industrial Facilities Storage and Terminal Solutions Total (In thousands) Net balance at June 30, 2022 $ 4,263 $ 18,427 $ 19,445 $ 42,135 Goodwill impairment — (12,316) — (12,316) Translation adjustment (1) (36) — (71) (107) Net balance at March 31, 2023 $ 4,227 $ 6,111 $ 19,374 $ 29,712 (1) The translation adjustments relate to the periodic translation of Canadian Dollar and South Korean Won denominated goodwill recorded as a part of prior acquisitions in Canada and South Korea, in which the local currency was determined to be the functional currency. We performed our annual goodwill impairment test as of May 31, 2022, which resulted in no impairment. The fiscal 2022 test indicated that four reporting units with a combined total of $33.8 million of goodwill as of June 30, 2022 were at higher risk of future impairment. Operating results during the second quarter of fiscal 2023 of one of our reporting units at higher risk of impairment indicated that it was more likely than not that its goodwill was impaired. This reporting unit is in the Process and Industrial Facilities segment and includes the midstream gas processing projects referenced in Note 2 - Revenue, Revisions in Estimates, which experienced a material adverse change in gross profit during the second quarter of fiscal 2023. Based on the indicated outcome of this project and our near-term outlook for the reporting unit, we performed an interim impairment test for the unit and concluded that its $12.3 million of goodwill was fully impaired. The impairment was recognized in operating loss during the second quarter of fiscal 2023. Based on the totality of both positive and negative factors, no impairment indicators related to the other reporting units existed at March 31, 2023. However, if our view of project opportunities or gross margins deteriorates, particularly for the remaining higher risk reporting units, then we may need to perform an interim goodwill impairment test, which could result in an impairment. During the three and nine months ended March 31, 2022, we concluded that goodwill impairment indicators existed based on the decline in the price of our stock and operating results that had underperformed during the year.

Debt Disclosure [Abstract]
Debt	Debt On September 9, 2021, the Company and our primary U.S. and Canada operating subsidiaries entered into an asset-based credit agreement, which was amended on October 5, 2022 (as amended, the "ABL Facility"), with Bank of Montreal, as Administrative Agent, Swing Line Lender and a Letter of Credit Issuer, and the lenders named therein. The maximum amount of loans under the ABL Facility is limited to $90.0 million. The ABL Facility's available borrowings may be increased by an amount not to exceed $15.0 million, subject to certain conditions, including obtaining additional commitments. The ABL Facility is intended to be used for working capital, capital expenditures, issuances of letters of credit and other lawful purposes. Our obligations under the ABL Facility are guaranteed by substantially all of our U.S. and Canadian subsidiaries and are secured by a first lien on all our assets and the assets of our co-borrowers and guarantors under the ABL Facility. The maximum amount that we may borrow under the ABL Facility is subject to a borrowing base, which is based on restricted cash plus a percentage of the value of certain accounts receivable, inventory and equipment, reduced for certain reserves. We are required to maintain a minimum of $25.0 million of restricted cash at all times, but such amounts are also included in the borrowing base. The ABL Facility matures, and any outstanding amounts become due and payable, on September 9, 2026. At March 31, 2023, our borrowing base was $78.5 million, we had $15.0 million of outstanding borrowings, and we had $19.3 million in letters of credit outstanding, which resulted in availability of $44.2 million under the ABL Facility. Borrowings under the ABL Facility bear interest through maturity at a variable rate based upon, at our option, an annual rate of either a base rate (“Base Rate”), an Adjusted Term Secured Overnight Financing Rate ("Adjusted Term SOFR"), or at the Canadian Prime Rate, plus an applicable margin. The Adjusted Term SOFR is defined as (i) the SOFR plus (ii) 11.448 basis points for a one-month tenor and 26.161 basis points for a three-month tenor; provided that the Adjusted Term SOFR cannot be below zero. The Base Rate is defined as a fluctuating interest rate equal to the greater of: (i) rate of interest announced by Bank of Montreal from time to time as its prime rate; (ii) the U.S. federal funds rate plus 0.50%; (iii) Adjusted Term SOFR for one month period plus 1.00%; or (iv) 1.00%. Depending on the amount of average availability, the applicable margin is between 1.00% to 1.50% for Base Rate and Canadian Prime Rate borrowings, which includes either U.S. or Canadian prime rate, and between 2.00% and 2.50% for Adjusted Term SOFR borrowings. Interest is payable either (i) monthly for Base Rate or Canadian Prime Rate borrowings or (ii) the last day of the interest period for Adjusted Term SOFR borrowings, as set forth in the ABL Facility. The fee for undrawn amounts is 0.25% per annum and is due quarterly. The interest rate in effect for borrowings outstanding at March 31, 2023, including applicable margin, was approximately 7.17%. The ABL Facility contains customary conditions to borrowings, events of default and covenants, including, but not limited to, covenants that restrict our ability to sell assets, engage in mergers and acquisitions, incur, assume or permit to exist additional indebtedness and guarantees, create or permit to exist liens, pay cash dividends, issue equity instruments, make distribution or redeem or repurchase capital stock. In the event that our availability is less than the greater of (i) $15.0 million and (ii) 15.00% of the commitments under the ABL Facility then in effect, a consolidated Fixed Charge Coverage Ratio of at least 1.00 to 1.00 must be maintained. We were in compliance with all covenants of the ABL Facility as of March 31, 2023.

Income Tax Disclosure	Income Taxes Effective Tax Rate Our effective tax rates were 2.8% and 0.7% for the three and nine months ended March 31, 2023, compared to 0.4% and (7.8%) during the three and nine months ended March 31, 2022, respectively. The effective tax rates during fiscal 2023 were impacted by valuation allowances of $3.6 million and $13.3 million placed on deferred tax assets during the three and nine months ended March 31, 2023, respectively. Valuation Allowance We placed a valuation allowance on our deferred tax assets in the second quarter of fiscal 2022 due to the existence of a cumulative loss over a three-year period. We will continue to place valuation allowances on newly generated deferred tax assets and will realize the benefit associated with the deferred tax assets for which the valuation allowance has been provided to the extent we generate taxable income in the future, or cumulative losses are no longer present and our future projections for growth or tax planning strategies are demonstrated. Net Operating Loss Carryback Refund Through provisions in the Coronavirus Aid, Relief, and Economic Security (CARES) Act (the "CARES Act"), we had an income tax benefit from the ability to carryback the fiscal 2021 federal net operating loss to a period with a higher statutory federal income tax rate. During the third quarter of fiscal 2023, we received a $13.3 million tax refund in connection with this carryback, which was included in income taxes receivable in the Condensed Consolidated Balance Sheet as of June 30, 2022. Deferred Payroll Taxes During the second quarter of fiscal 2023, we repaid the remaining $5.6 million of U.S. payroll taxes we deferred through provisions of the CARES Act. The balance of deferred payroll taxes was included within accrued wages and benefits in the Condensed Consolidated Balance Sheet as of June 30, 2022.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Insurance Reserves We maintain insurance coverage for various aspects of our operations. However, we retain exposure to potential losses through the use of deductibles, self-insured retentions and coverage limits. Typically, our contracts require us to indemnify our customers for injury, damage or loss arising from the performance of our services and provide warranties for materials and workmanship. We may also be required to name the customer as an additional insured up to the limits of insurance available, or we may be required to purchase special insurance policies or surety bonds for specific customers or provide letters of credit in lieu of bonds to satisfy performance and financial guarantees on some projects. We maintain a performance and payment bonding line sufficient to support the business. We generally require our subcontractors to indemnify us and our customer and name us as an additional insured for activities arising out of the subcontractors’ work. We also require certain subcontractors to provide additional insurance policies, including surety bonds in favor of us, to secure the subcontractors’ work or as required by the subcontract. There can be no assurance that our insurance and the additional insurance coverage provided by our subcontractors will fully protect us against a valid claim or loss under the contracts with our customers. Unpriced Change Orders and Claims Costs and estimated earnings in excess of billings on uncompleted contracts included revenues for unpriced change orders and claims of $14.7 million at March 31, 2023 and $8.9 million at June 30, 2022. The amounts ultimately realized may be significantly different than the recorded amounts resulting in a material adjustment to future earnings. The determination of our legal basis for a claim requires significant judgment. Generally, collection of amounts related to unpriced change orders and claims is expected within twelve months. However, since customers may not pay these amounts until final resolution of related claims, collection of these amounts may extend beyond one year. Other During the third quarter of fiscal 2020, we commenced litigation in an effort to collect accounts receivable from an iron and steel customer following the deterioration of the relationship in the second quarter of fiscal 2020. The unpaid account receivable balance at March 31, 2023 was $17.0 million. Litigation is unpredictable; however, based on the terms of the contract with this customer, we believe we are entitled to collect the full amount owed under the contract. We are participants in various legal actions. It is the opinion of management that none of the other known legal actions will have a material impact on our financial position, results of operations or liquidity.

Segment Reporting [Abstract]
Segment Information	Segment Information We report our results of operations through three reportable segments: Utility and Power Infrastructure, Process and Industrial Facilities, and Storage and Terminal Solutions. • Utility and Power Infrastructure : consists of power delivery services provided to investor-owned utilities, including construction of new substations, upgrades of existing substations, transmission and distribution line installations, upgrades and maintenance, as well as emergency and storm restoration services. We also provide engineering, fabrication, and construction services for LNG utility peak shaving facilities, and provide construction and maintenance services to a variety of power generation facilities, including natural gas fired facilities in simple or combined cycle configuration. • Process and Industrial Facilities : primarily serves customers in the downstream and midstream petroleum industries who are engaged in refining crude oil and processing, fractionating, and marketing of natural gas and natural gas liquids. We also serve customers in various other industries such as petrochemical, sulfur, mining and minerals companies engaged primarily in the extraction of non-ferrous metals, aerospace and defense, cement, agriculture, and other industrial customers. Our services include plant maintenance, turnarounds, industrial cleaning services, engineering, fabrication, and capital construction. • Storage and Terminal Solutions : consists of work related to aboveground crude oil and refined product storage tanks and terminals. We also include work related to cryogenic and other specialty storage tanks and terminals, including LNG, liquid nitrogen/liquid oxygen, liquid petroleum, hydrogen and other specialty vessels such as spheres in this segment, as well as work related to marine structures and truck and rail loading/offloading facilities. Our services include engineering, fabrication, construction, and maintenance and repair, which includes planned and emergency services for both tanks and full terminals. Finally, we offer tank products, including geodesic domes, aluminum internal floating roofs, floating suction and skimmer systems, roof drain systems and floating roof seals. We evaluate performance and allocate resources based on operating income. We eliminate intersegment sales; therefore, no intercompany profit or loss is recognized. Corporate selling, general and administrative expenses are excluded from our three reportable segments in order to align controllable costs with the responsibility of segment management, and to be consistent with how our chief operating decision-maker assesses segment performance and allocates resources. In fiscal year 2022, we commenced a project to centralize and standardize certain support functions including accounting, human resources and project support. These centralized support functions are now included in corporate selling, general and administrative expense, but were previously included in our operating segment selling, general and administrative expense. Segment assets consist primarily of accounts receivable, costs and estimated earnings in excess of billings on uncompleted contracts, property, plant and equipment, right-of-use lease assets, goodwill and other intangible assets.

Restructuring and Related Activities [Abstract]
Restructuring Costs	Restructuring Costs In fiscal 2020, we initiated a business improvement plan to increase profitability and reduce our cost structure in order to help us become more competitive and deliver higher quality service. As a result of specific events, including the effects of the COVID-19 pandemic and related market disruptions, the Company expanded its business improvement plan. The business improvement plan consists of an initial phase of discretionary cost reductions, workforce reductions, reduction of capital expenditures and the reduction in size or closure of certain offices in order to increase the utilization of our staff and bring the cost structure of the business in line with revenue volumes. In fiscal 2022, we commenced a second phase of our plan to focus on centralization of support functions, including business development, accounting, human resources, procurement and project services into shared service centers. During the second quarter of fiscal 2023, we closed an underperforming office and ceased its associated operations, which resulted in $0.7 million of restructuring costs. We expect to complete these restructuring efforts in fiscal 2023 or early fiscal 2024. The restructuring costs consist primarily of severance costs, facility closure costs, consulting fees and other liabilities. Restructuring costs under our business improvement plan are classified as follows: Three Months Ended Nine Months Ended Since Inception of Business Improvement Plan March 31, 2023 March 31, 2022 March 31, 2023 March 31, 2022 (In thousands) Restructuring Costs by Type: Severance and other personnel-related costs $ 251 $ — $ 2,563 $ 136 $ 17,477 Facility costs 50 12 179 29 4,709 Other intangible asset impairments — — — — 1,525 Other costs 15 (1,590) 139 (443) 582 Total restructuring costs $ 316 $ (1,578) $ 2,881 $ (278) $ 24,293
