     THE KEITH COMPANIES REPORTS RECORD QUARTERLY NET REVENUE
     FOR FIRST QUARTER 2005 AND NET INCOME INCREASED BY 29.8%

     o    Net Revenue Increased 15.3% to $25.9 Million
     o    Diluted Earnings Per Share Increased 26.3% to $0.24 Per Share

IRVINE, CA (May 5, 2005) - The Keith Companies, Inc. (Nasdaq: TKCI), an
engineering and consulting services firm, today announced financial results for
the first quarter ended March 31, 2005, which included record quarterly net
revenue and a 29.8% increase in net income.

FIRST QUARTER 2005 RESULTS
     Net revenue for the three months ended March 31, 2005 increased 15.3% to
$25.9 million, while net income for the same period increased 29.8% to $1.9
million resulting in diluted earnings per share of $0.24. This compares to net
revenue for the first quarter of 2004 of $22.5 million, with net income of $1.5
million and diluted earnings per share of $0.19.

     "All three of our business segments achieved year-over-year net revenue
growth in the first quarter, led by continued strong gains in the real estate
development segment," said Aram Keith, Chairman and CEO of The Keith Companies.
"This segment achieved an 18.4% year-over-year net revenue growth in the first
quarter, helping to drive a record level of quarterly net revenue for The Keith
Companies. We continue to see a lot of real estate activity not only in the
residential sector, which has been an area of tremendous growth for us, but also
in the commercial, office, retail and industrial sectors. Operating margins
remained strong in our real estate segment and we see no signs of demand in this
area abating. While we continue to experience reduced overall demand in the
public works/infrastructure segment, this segment experienced an increase in net
revenue over prior year mainly because we were able to partially mitigate the
impact of this reduced demand during the quarter by temporarily deploying some
of the under utilized engineers to assist in our real estate development
segment. Our energy/industrial segment delivered net revenue growth and swung
from an operating loss in the first quarter of 2004 to a profit in the same
period of 2005. Renewable energy projects are picking up as a result of the
Production Tax Credit extension and we are also seeing increased

activity in the industrial market as well. We expect continued strength in our
overall business for the remainder of 2005."

FINANCIAL POSITION
     The Company's balance sheet at March 31, 2005 remained strong with cash and
securities of $40.2 million, no debt, a current ratio of 5.3:1, and
shareholders' equity of $84.2 million, or $10.55 per common share outstanding at
March 31, 2005.

FINANCIAL GUIDANCE
     Due to the pending merger with Stantec discussed below, the Company has
decided to discontinue its practice of providing financial guidance on future
operating results. Investors are cautioned not to place any reliance on the
financial guidance that the Company last provided on February 10, 2005.

MERGER WITH STANTEC INC.
     The Company announced on April 14, 2005 that it entered into an agreement
with Stantec Inc. (TSX: STN) by which the two firms would combine, subject to
approval of the transaction by shareholders of The Keith Companies, and the
expiration of the waiting period under the Hart-Scott-Rodino Act and other
customary conditions.

     "This is an exciting transaction for The Keith Companies' employees,
clients, and shareholders," says Aram Keith, The Keith Companies' Chairman and
CEO. "Joining Stantec will substantially accelerate our growth plans and make
The Keith Companies a part of a North American firm with a widely diversified
service offering. Our employees will have access to more service specialists,
experts, and greater technological resources while our clients will gain access
to a wider range of services," concluded Keith.

     This press release contains forward-looking statements. In some cases,
forward-looking statements can be identified by words such as "believe,"
"expect," "anticipate," "plan," "potential," "continue" or similar expressions.
Such forward-looking statements are based upon current expectations and beliefs
and are subject to a number of factors and uncertainties that could cause actual
results to differ materially from those described in the forward-looking
statements. Some of the forward-looking statements contained in this press
release include: (i) our expectation of continued growth in the real estate
development sector, (ii) our expectation that operating margins in the real
estate development sector will continue to be strong, (iii) our expectation of
continued improvement in the energy/industrial sector and (iv) our statements
regarding the proposed merger with Stantec. These statements are not guarantees
of future performance, involve certain risks, uncertainties and assumptions that
are difficult to predict, and are based upon assumptions as to future events
that may not prove accurate. Therefore, actual outcomes and results may differ
materially from what is expressed herein. For example, if TKC does not receive
required shareholder approvals, if Stantec is unable to list its stock on a
major U.S. exchange or if either party fails to satisfy other conditions to
closing, the merger will not be consummated. In addition, the combined companies
may not realize all or any of the expected benefits of the merger. The following
factors, among others, could cause actual results to differ materially from
those described in the forward-looking statements: changes in the economic
growth in the United States (especially in California) and other major
international economies, our ability to sustain our growth and profitability, a
downturn in the real estate market, the ongoing financing of public works and
infrastructure enhancements and refurbishments, the demand for electricity and
the impact on power providers' plans for expanding generation facilities, our
failure to accurately estimate costs on fixed-price contracts or contracts with
not-to-exceed provisions, changes in the carrying value of our goodwill and
other long-term assets, our ability to implement our acquisition strategy and to
successfully close and integrate acquired companies on a timely and
cost-effective basis while maintaining their profit margins and/or client base,
our ability to attract and retain employees, the uncertain timing of awards and
contracts, our ability to successfully implement our enterprise service
automation software system, outcomes of pending and future litigation,
increasing competition by domestic and foreign companies, risks inherent in
doing business outside the United States, including the difficulty of enforcing
contracts, political instability and foreign currency fluctuations and potential
exchange restrictions, the short and long-term impact of terrorist activities
and resulting political and military policies, and other factors as are
described in the Company's filings with the SEC. The forward-looking information
set forth in this press release is as of the date indicated above and we
undertake no duty to update this information. Actual results may differ
materially from those contained in the forward-looking statements in this press
release.
