Opinion
We granted review in this case to decide whether the project stabilization agreement (PSA) executed by defendant San Francisco Airports Commission (the Commission) and real party in interest San Mateo County Building and Construction Trades Council, AFL-CIO (the Trades Council), in order to accomplish the $2.4 billion expansion and renovation of the San Francisco International Airport, violates competitive bidding laws or certain other statutory or constitutional provisions.
The PSA involved in the present case exacts from the signatory unions over the expected 10-year life of the project a no-strike pledge, an agreement to arbitrate jurisdictional disputes among crafts, and a promise to continue work on the project despite the expiration of any applicable collective bargaining agreements. In exchange, the Commission agrees to require all contractors to accept the terms of the PSA, to abide by each craft’s labor-management grievance procedure in cases of discipline or discharge, and to *359 use the union hiring hall for any new hires needed beyond the employer’s own core workforce. Employers are also required to pay union wages and benefits. 1
The PSA is an example of a type of prehire agreement designed for large and complex construction projects. It is designed to eliminate potential delays resulting from labor strife, to ensure a steady supply of skilled labor on the project, and to provide a contractually binding means of resolving worker grievances. Such agreements, also called project labor agreements, have long been used in large construction projects undertaken by both private concerns and, especially following the decision of the United States Supreme Court in
Building & Constr. Trades Council
v.
Associated Builders & Contractors of Mass./R. I., Inc.
(1993)
In order to protect the right of workers freely to choose their bargaining representatives, the NLRA generally prohibits prehire agreements. By enacting what is often called the construction industry proviso in 1959 (see 29 U.S.C. § 158(f)), however, Congress recognized that special conditions prevailing in the construction industry warrant an exception to the general rule. Because of the typically short-term and occasional nature of employment with any given employer in the construction industry, Congress determined that “[representation elections in a large segment of the industry are not feasible to demonstrate . . . majority status . . . .” (Sen.Rep.

v.
Iron Workers
(1978)
Bids for the international terminal contract, the largest contract in the airport expansion project, were due July 11, 1996. On that day, Associated Builders and Contractors, Inc., Golden Gate Chapter, and the Asian American Contractors Association, Inc. (AACA) (collectively, ABC), appeared in the San Francisco County Superior Court seeking a writ of mandate to strike the PSA requirement from the bid specifications, arguing the PSA is unconstitutional and violates state competitive bidding statutes. Following a hearing on the merits, the superior court denied the petition, ruling that the PSA is not unconstitutional and finding no inconsistency between the PSA and the competitive bidding laws. The Court of Appeal affirmed. That court held: the decision to use a PSA for the airport expansion project is a matter of local concern governed by San Francisco’s Administrative Code rather than the California Public Contract Code; regardless of whether state or local law applied, the PSA does not violate competitive bidding laws; the PSA does not violate ABC’s constitutional rights; and ABC lacks standing to assert violations of its workers’ rights under the Labor Code.
We granted ABC’s petition for review.

Standard of review
On appeal from the denial of a writ of mandate, courts generally review an administrative agency’s action under the substantial evidence test. We do not inquire whether, if we had the power to do so, we would have taken the action taken by the agency.

Whether ABC has standing to challenge the PSA under competitive bidding laws
Preliminarily, the Commission maintains ABC lacks standing to challenge the legality of the PSA under the competitive bidding laws. The Commission acknowledges it did not raise below all the arguments regarding standing it now presents in its brief, but observes that “ ‘contentions based on a lack of standing involve jurisdictional challenges and may be raised at any time in the proceeding.’

To establish associational standing, ABC must demonstrate that its members would otherwise have standing to sue in their own right.
(Brotherhood of Teamsters & Auto Truck Drivers
v.
Unemployment Ins. Appeals Bd.
(1987)
ABC predicates its allegation of standing on a declaration by John Robinson, the Executive Director of the Golden Gate Chapter of Associated Builders and Contractors, Inc., stating that seven named members of Associated Builders and AACA refused to bid on the airport project due to the PSA specification. ABC also appears to rely on an allegation that, as citizens and taxpayers of this state, ABC’s members have a beneficial interest in ensuring that no worker is denied access to employment on a public works project by the operation of the union hiring hall provisions of the PSA.
The Commission contends ABC’s claim of associational standing must fail, because the Robinson declaration does not establish that ABC’s members have bid in the past or have the necessary qualifications, such as a proper license, to submit a valid bid in the future. (See
Cornelius

ABC responds that its standing stems from the injury visited on its members by being precluded from competing for airport contracts on an equal basis with union contractors. (See

Whether state or local competitive bidding law applies
As a charter city, San Francisco enjoys autonomous rule over municipal affairs pursuant to article XI, section 5 of the California Constitution, “subject only to conflicting provisions in the federal and state Constitutions and to preemptive state law.”
(Domar, supra,
*364
The Commission disputes some of these assertions, noting that the airport is owned and operated by the City and County of San Francisco, that San Mateo County’s (not the state’s) prevailing wage rates apply only because the San Francisco Board of Supervisors selected those rates as the applicable measure (see S.F. Charter, appen. A, § A7.204; S.F. Admin. Code, §§ 6.38, 6.39;
Vial
v.
City of San Diego
(1981)
The Commission’s argument appears the better supported by authority, but we need not resolve the question, because the parties point to no substantive difference in the outcome of this case dependent on the application of state or local competitive bidding law. In resolving whether state or local law applies, the court must first determine whether a genuine conflict between those laws in fact exists. (Johnson v. Bradley, supra, 4 Cal.4th at pp. 400-401.) Only if the court concludes an actual conflict exists should it go on to analyze whether the state law addresses a matter of statewide concern. (California Fed. Savings & Loan Assn. v. City of Los Angeles, supra, 54 Cal.3d at pp. 16-17.)
*365 As the Court of Appeal in this case recognized and as all parties seem to agree, California Public Contract Code section 20128, requiring contracts be let to the “lowest responsible bidder,” and San Francisco Administrative Code section 6.1, using the formulation “lowest reliable and responsible bidder,” do not conflict. We therefore need not determine whether the inclusion of the PSA specification in the airport project bid request involves a matter of statewide concern.
Whether the PSA is consistent with competitive bidding law
Because the relevant language of the state and local competitive bidding laws, quoted in the immediately preceding paragraph, does not dispositively address the question before us, our analysis must focus on whether the PSA is consistent with the general principles underlying the competitive bidding law. As will appear, because the PSA requirement does not bar or substantially discriminate against a class of contractors, we conclude in the affirmative. Given that determination, in the next part of this opinion we address whether the record contains substantial evidence that the PSA furthers a legitimate governmental interest that is consistent with the competitive bidding law and thus supports the Commission’s decision to require agreement to the PSA as a condition of contractors’ participation in the project.
Recently, in
Domar, supra,

The term “lowest responsible bidder” has been construed to mean “ ‘the lowest bidder whose offer best responds in quality, fitness, and capacity to the particular requirements of the proposed work.’ ”
(City of Inglewood-L.A. County Civic Center Auth.
v.
Superior Court
(1972)
Our first step is to consider the PSA in light of the purposes of the competitive bidding laws to determine whether it serves those purposes, or instead has the anticompetitive effect of excluding from the project, or denying equal opportunity to, any categories of potential bidders. (See Domar, supra, 9 Cal.4th at p. 173.)
ABC complains the imposition of the PSA is anticompetitive in that it “deters non-union contractors from bidding because it requires contractors to sign an agreement with the union and use only union supplied labor, pay into union benefit funds and adopt union wage rates.” 2 (Underscoring in original.) ABC further argues the PSA violates the competitive bidding law because it contains various provisions that are unrelated to the quality, cost, or timeliness of the work and that, therefore, do not serve the purposes of the competitive bidding law. ABC’s arguments fail to persuade us, because they lack support in the record and, at bottom, constitute an invitation to reweigh the considerations presented to the Commission.
“[Competitive bidding' requirements ‘necessarily imply equal opportunities to all whose interests or inclinations may impel them to
*367
compete at the bidding.’ [Citation.]”
(Domar, supra,
As ABC expressly acknowledges, the PSA, by its terms, excludes no contractor, union or nonunion, from bidding on the airport project. Further, the PSA exacts from contractors no commitment toward the unions on any other project, has no effect on a contractor’s parent companies, subsidiaries or affiliates, and does not apply to a contractor’s managerial, supervisorial, executive or clerical employees. ABC relies on

Assoc. Gen. Contr. of Cal.
v.
City & County of S.F.
(9th Cir. 1987)
As for the PSA’s requirement that contractors engage new employees through the union hiring hall, it must be recalled that the PSA permits a
*368
contractor to use every member of its core work force, defined as persons on the contractor’s active payroll for 60 of the preceding 100 days, in performing work under the project before requiring resort to the union hiring hall. Federal law, moreover, requires union hiring halls to refer both union members and nonmembers to available jobs.
(Woelke & Romero Framing, Inc.
v.
NLRB
(1982)
As ABC acknowledges, the prevailing wage law, not the PSA, is the source of the applicable wage rates. (See S.F. Charter, appen. A, § A7.204 [“Every contract for any public work or improvement. . . must provide: [^] . . . [ID (b) that any person performing labor thereunder shall be paid not less than the highest general prevailing rate of wages in private employment for similar work; . . .”].) We have observed that prevailing wage laws are designed in part to permit union and nonunion contractors to compete on an even footing for public contracts.
(Lusardi Construction Co.
v.
Aubry
(1992)
*369 ABC suggests the PSA will raise the costs of the project because nonunion contractors would be able to use semiskilled or unskilled workers in place of some of the journeymen required to staff projects in union shops. No facts in the record support this suggestion, which appears to be potentially contrary to both state and federal law applicable to prevailing wage public works jobs. (See Lab. Code, § 1777.5 [only apprentices in approved apprenticeship programs who are paid at standard apprentice wage may be employed on public works]; cf. 29 C.F.R. § 5.5(a)(4)(i), (ii) (1998) [wage requirements for apprentices and trainees on federally funded public works projects].) Moreover, a bidder is not at liberty to lower its costs by substituting unskilled “helpers” for any skilled workers demanded by the contract specifications; ABC does not contend the contracting agency lacks discretion to specify standards for the performance of the work under contract.
As the Court of Appeal aptly observed, “If ABC chooses not to bid, that is its right, the exercise of which is strictly within its control.” ABC members’ election not to bid on the airport project, out of a desire to avoid dealing with unions or for whatever other reasons, does not make the PSA anticompetitive.
Judicial decisions in other jurisdictions are largely in accord with this conclusion, and those few that invalidate project labor agreements either do so under competitive bidding laws that, unlike those applicable to this case, emphasize “unfettered competition” over more generalized public interest considerations, or employ a less deferential standard of review of agency decisionmaking than obtains in this state.

ABC directs us to no authority supporting the existence of a policy of “unfettered competition” underlying the competitive bidding law of California. While Public Contract Code section 10115 (located in an article creating minority and women participation goals for state contracts) extols the value of free competition in the American economic system, that statute does not alter the policies underlying the competitive bidding laws, as set forth in
Domar, supra, 9
Cal.4th at page 173, and reiterated above. Indeed, as mentioned, the competitive bidding laws are “ ‘enacted for the benefit of property holders and taxpayers, and not for the benefit or enrichment of bidders, and should be so construed and administered as to accomplish such
*373
purpose fairly and reasonably with sole reference to the public interest.’ ”

Moreover, it appears the New Jersey Supreme Court employs a standard of review of administrative agency quasi-legislative decision-making that is much less deferential than that prevailing in this state. (See

ABC complains that, contrary to the argument of the Trades Council, a contractor may not necessarily be able to comply with the PSA requirement if that contractor’s employees have previously rejected the pertinent union in an election, or if the contractor either has signed a collective bargaining agreement or is in negotiation with a different labor organization, as in
George Harms, supra,
Whether substantial evidence supports the Commission’s adoption of the PSA bid specification
The familiar principles constraining our review are easily reiterated: In determining whether the Commission’s decision to adopt the PSA bid specification was supported by substantial evidence, we resolve all conflicts in favor of the prevailing party, indulging in all legitimate and reasonable inferences from the record. When a finding is attacked as being unsupported, the power of the appellate court begins and ends with a determination as to whether there is any substantial evidence in the record, contradicted or uncontradicted, that will support the finding. When two or more inferences can be reasonably deduced from those facts, the reviewing court has no power to substitute its deductions for those of the fact finder.
(WSPA, supra,
We conclude substantial evidence supports the Commission’s adoption of the PSA bid specification as being in furtherance of legitimate governmental interests. Consistent with the competitive bidding laws, these interests include preventing costly delays and assuring contractors access to skilled craft workers. The record reflects that the Commission was concerned about the potential for labor strife during the life of the project. Before voting on the resolution adopting the PSA, the Commission held two public meetings to hear evidence and argument on the desirability of the agreement. 4 As the Court of Appeal observed: “Seventy-seven separate construction contracts were interrelated by time and effect. John L. Martin, *375 director of airports, whose declaration was submitted by the Commission in opposition to ABC’s petition below, stated that for every month of delay in completion of the master plan, it was estimated that the cost of administering the project would increase by $1.5 million, and the Commission would lose revenue of $13 million. Inflation alone would add an additional $4,635,000 monthly to the cost of the master plan. In addition, there would be increased expenditures needed for the continuation of temporary facilities, and an unquantifiable loss of tourist revenue to San Francisco. Director Martin noted that significant delays in the completion of one contract would likely have a ‘domino effect’ by causing delays in the completion of other, later-in-time contracts.” On the other hand, the Commission had before it no evidence that the cost of prosecuting the work contemplated by the master plan would increase as a result of the PSA compliance requirement. The PSA includes provisions designed to prevent strikes, slowdowns and other work stoppages, and to ensure contractors a steady and rehable source of skilled labor for the project. In view of the evidence before the Commission demonstrating the substantial costs associated with preventable delays, we cannot say that the adoption of the PSA requirement was arbitrary, capricious, or lacking in evidentiary support. The Commission could properly find that these provisions serve the goals of the competitive bidding laws, in particular to “ ‘secure the best work or supplies at the lowest price practicable ... for the benefit of property holders and taxpayers, and not for the benefit or enrichment of bidders.’ ” (Domar, supra, 9 Cal.4th at p. 173.)
ABC argues the Commission could not properly act on such concerns absent evidence of labor unrest on prior projects at the airport or without considering narrower solutions, such as requiring only union contractors to agree to no-strike clauses. ABC does not persuade us the Commission’s discretion was so constrained. We rejected an analogous argument in Domar, supra, 9 Cal.4th at page 174, that a minority/women outreach program imposed as a bid requirement had to be shown actually to promote competition or reduce prices. “Despite the lack of empirical evidence,” we said, “it is not unreasonable for the Board to conclude that, in the absence of mandated outreach, prime contractors will tend to seek out familiar subcontractors when bidding for projects, and that therefore their bids may or may not reflect as low a price had reasonable outreach efforts been made. Indeed, Domar is unable to cite to anything in the record that might detract from *376 such a conclusion. Under these circumstances, the Board’s action is entitled to deference.” {Ibid.) Similarly here, the Commission was not required to seek evidence of past labor strife at the airport, or await future labor unrest, before bargaining for a no-strike agreement designed to avoid costly delays in the completion of the project.
ABC, moreover, cannot exclude the possibility that nonunion workers might engage in a strike, slowdown or other job action; it merely argues such action by nonunion workers is unlikely. The Commission was not, however, required to rely on the asserted unlikelihood of such action and thus to exempt nonunion workers from the no-strike pledge.
ABC asserts that unspecified federal and state labor laws already exist to deal with the possibility of labor unrest. Hence, it urges, adoption of the PSA was unwarranted.
5
As the Trades Council correctly argues, however, labor unrest is not illegal in this country. Only through some form of collective bargaining agreement can the Commission and the employers on the project eliminate workers’ right to strike. (See
Boys Markets
v.
Clerks Union
(1970)
Having concluded ABC has failed to demonstrate that the PSA in the present case conflicts with competitive bidding laws, we observe that future challenges to the imposition of project labor agreements as bid requirements will be reviewed, on a case-by-case basis, for consistency with the competitive bidding laws under the principles articulated in this opinion. 6
*377 Whether the PSA violates Labor Code section 923, 1779, or 1780
Labor Code section 923 declares that the public policy of California favors the rights of individual workers to freedom of association, self-organization, the designation of representatives of their choice, negotiation of the terms and conditions of their employment, and freedom from interference or restraint by employers in the exercise of those rights. 7 ABC contends the PSA frustrates the right of its members’ workers under this statute by precluding them from choosing for themselves whether to be represented by the relevant craft union.
There are several problems with ABC’s argument. First, as the Commission and the Trades Council point out, ABC lacks standing to assert the organizational rights of the workers employed by its members. None of the cases ABC cites in an attempt to demonstrate it possesses standing to do so are relevant,
8
and other courts addressing the issue in the context of project
*378
labor agreements have uniformly rejected attempts by contractor associations to assert standing on behalf of their members’ employees. (See, e.g.,
Assoc. Gen. Contractors
v.
Otter Tail Power
(8th Cir. 1979)
Second, ABC’s argument lacks merit under state law. The California statutes that declare and protect workers’ rights to self-determination in matters of labor organization cannot reasonably be construed to invalidate project labor agreements. Courts have held that even agency shop agreements are lawful in this state; a fortiori, project labor agreements, which restrict workers’ freedom to a lesser degree, must also be lawful.
(Petri Cleaners, Inc.
v.
Automotive Employees, etc., Local No. 88
(1960)
Finally, ABC’s argument fails to come to terms with the supremacy of federal labor law, embodied in 29 United States Code section 158(f), which permits prehire agreements in the construction industry. Any California law purporting to bar such agreements would raise serious questions of preemption under
Machinists
v.
Wisconsin Emp. Rel. Comm’n
(1976)
ABC forfeited its contentions regarding Labor Code sections 1779 and 1780 by failing to raise them at a prior stage of this litigation, and we therefore need not address them. (Cal. Rules of Court, rule 29(b)(1).) Were we to do so, how they would provide a basis for invalidating the PSA requirement is in any event unclear. These statutes are criminal anti-kickback laws;
9
ABC cites no authority supporting its implicit argument that they create a private right of action against a public entity for imposition of
*380
a bid requirement. Moreover, nothing in the record supports ABC’s accusation that union hiring halls charge fees for usage. The discriminatory charging of such fees, we note, may be an unfair labor practice under federal law. (See 29 U.S.C. § 158(b)(5);

Whether the PSA requirement infringes ABC’s constitutional rights of association and equal protection
Relying chiefly on
O’Hare Truck Service, Inc.
v.
City of Northlake
(1996)
Even if we could conclude the PSA somehow burdens ABC’s political views, we observe that the high court in
O’Hare
recognized: “Cities and other governmental entities make a wide range of decisions in the course of contracting for goods and services. The Constitution accords government officials a large measure of freedom as they exercise the discretion inherent in making these decisions. [Citation.] Interests of economy may lead a governmental entity to retain existing contractors or terminate them in favor of new ones without the costs and complexities of competitive bidding. A government official might offer a satisfactory justification, unrelated to the suppression of speech or associational rights, for either course of action. The first may allow the government to maintain stability, reward good performance, deal with known and reliable persons, or ensure the uninterrupted supply of goods or services; the second may help to stimulate competition, encourage experimentation with new contractors, or avoid the appearance of favoritism. These are choices and policy considerations that ought to remain open to government officials when deciding to contract with some firms and not others, provided of course the asserted justifications are not the pretext for some improper practice.”
(O’Hare, supra,
518 U.S. at pp. 724-725 [
As discussed above, the Commission could reasonably determine the PSA would further the aims of the competitive bidding law and the public interest. To whatever extent the PSA specification might be seen to burden ABC’s political expression, the Commission, in the words of the
O’Hare
court, could properly conclude the specification is “ ‘an appropriate requirement for the effective performance’ of the task in question.”
(O’Hare, supra,
In passing, ABC asserts the PSA violates state and federal constitutional guarantees of equal protection (U.S. Const., Amend. XIV; Cal. Const., art. I, § 7 and art. IV, § 16) in discriminating against contractors and their employees based on their political beliefs. ABC abandoned these contentions by failing to raise them in its arguments before the Court of Appeal. (Cal. Rules of Court, rule 29(b)(1).) In any event, as noted, the PSA excludes no
*382
contractor or employee; any contractor, whether union or nonunion, is free to bid on the project. Consequently, ABC fails to establish that its members or their employees are denied equal protection under either the state or the federal charter. (See
Associated Builders & Contractors

Contra Costa Water Dist.

Conclusion
The judgment of the Court of Appeal is affirmed.
George, C. J., Mosk, J., Kennard, J., Baxter, J., Chin, J., and Brown, J., concurred.
Notes
Because the airport project is subject to the prevailing wage law, however, employers on the project must, in essence, pay union wages regardless of the PSA. (See S.F. Charter, appen. A, § A7.204.)
For the first time in this litigation, ABC also asserts that the PSA’s exclusive hiring hall provisions, mandatory grievance procedure and designated employee benefit trust fund contribution requirements violate the sole source restriction contained in Public Contract Code section 3400. ABC’s failure to plead this contention below precludes it from doing so here. Moreover, ABC fails to provide any analysis or argument in support of the assertion, which, for this additional reason, is not properly raised.
(People
v.
Barnett
(1998)
We observe that the
Tormee
court suggested a project labor agreement might be valid if it possessed some of the features shared by the PSA in the present case, such as the absence of a requirement that the successful bidder be a union contractor and allowing a contractor to retain a core of its workforce.
(Tormee, supra,
143 N.J. at pp. 149-150 [
As the Commission observes, however, the fact that two public meetings were held, resulting in fact-finding, does not alter the quasi-legislative character of the Commission’s adoption of the PSA. (See
20th Century Ins. Co.
v.
Garamendi, supra,
By request filed on April 20, 1998, the Commission asks this court to take judicial notice of the transcripts of the two public hearings it conducted before adopting the PSA bid specification. In support of the request, the Commission relies on Evidence Code sections
*375
452, subdivision (c), and 459, subdivision (a), which permit courts to take judicial notice of “[o]fficial acts of the . . . executive . . . departments of. . . any state of the United States,” and which have been read to allow judicial notice of administrative agency records. (See
Fowlers. Howell
(1996)
ABC also asserts that “the evidence overwhelming[ly] proves that PSAs raise project costs and reduce the number of bidders.” ABC proceeds to cite certain materials, never presented to the Commission, that purportedly support its assertion. In response, the Trades Council requests that we exercise our authority under rule 18 of the California Rules of Court to strike from ABC’s brief all references to matters not found in the record. We do not consider these factual assertions, along with numerous others in ABC’s brief, that find no basis in the record. (See
WSPA, supra,
The Commission has moved this court to strike or disregard ABC’s supplemental brief, contending the declarations comprising part of the brief set forth irrelevant hearsay and violate rule 13 of the California Rules of Court and principles articulated in WSPA, supra, 9 *377 Cal.4th at page 574, by referring to factual matters outside the record. ABC contends its brief is proper under rule 29.3 of the California Rules of Court, which provides that “[w]hen a party desires to present new authorities, newly enacted legislation, or other intervening matters, not available in time to have been included in the party’s brief on the merits, the party may serve and file a supplemental brief’ within specified time limits. (Cal. Rules of Court, rule 29.3(a).) Rule 29.3, however, addresses the timing of appellate supplemental briefing, but does not purport to specify what matters a court may properly consider in deciding a case. The latter is a question that must be answered by reference to generally applicable legal principles. We agree with the Commission’s characterization of the declarations as improper, and therefore disregard them. We have considered the two judicial decisions comprising the remainder of ABC’s supplemental brief, as we would any other cited cases, and conclude neither of them constitutes authority for invalidating the PSA requirement.
ABC’s requests for judicial notice of certain newspaper articles and excerpts from a report of a consultant to the Metropolitan Water District of Southern California are denied.
“Negotiation of terms and conditions of labor should result from voluntary agreement between employer and employees. Governmental authority has permitted and encouraged employers to organize in the corporate and other forms of capital control. In dealing with such employers, the individual unorganized worker is helpless to exercise actual liberty of contract and to protect his freedom of labor, and thereby to obtain acceptable terms and conditions of employment. Therefore it is necessary that the individual workman have full freedom of association, self-organization, and designation of representatives of his own choosing, to negotiate the terms and conditions of his employment, and that he shall be free from the interference, restraint, or coercion of employers of labor, or their agents, in the designation of such representatives or in self-organization or in other concerted activities for the purpose of collective bargaining or other mutual aid or protection.” (Lab.
