The issue before us is whether a municipality can award a contract to a low bidder that fails to include with its bid a required consent of surety to provide a performance bond. In an unreported opinion, the Appellate Division affirmed the trial court’s ruling that the omission of a consent of surety from the bid is a defect that can be temporarily waived and subsequently cured.

The essential facts are undisputed. Defendant Borough of Island Heights (Borough) had a three-year contract with plaintiff, Meadowbrook Carting Company, Inc. (Meadowbrook), for the collection and removal of garbage, which was due to expire on February 1, 1993. Pursuant to the requirements of the Local Public Contracts Law, N.J.S.A. 40A:11-1 to -49, the Borough advertised in November 1992 for bids on a new three-year contract commencing February 1, 1993. The advertisements notified potential bidders that they were required to submit a sealed bid in accordance with the specifications by January 29, 1993.
The bid specifications were consistent with various provisions of the Local Public Contracts Law. Pursuant to N.J.S.A 40A:11-21, the bid specifications required “[b]id security in the form of a certified check, cashier’s check or bid bond in the amount of 10% of the bid but not to exceed $20,000” to be submitted with the bid proposal. The specifications also required the party to whom the contract was awarded to furnish a “[performance] bond of any indemnity company authorized to do business in the State of New Jersey and satisfactory to the Borough for the full amount of the *311 bid, as accepted, and [to] pay all premiums due thereon.” As required by N.J.S.A. 40A: 11-22, the bid specifications mandated that bidders submit "with their bid proposal a consent of surety guaranteeing that a bonding company will issue a performance bond in accordance with the bid specifications. The specifications defined a “consent of surety” as a “statement submitted with a bid, from a surety company duly authorized to do business in New Jersey and satisfactory to the governing body to the effect that said surety company will furnish a bond for the bidder, if awarded the contract.” Each bidder was also required to provide a statement disclosing the identity of the owners of the bidding enterprise, and a Certificate of Insurance verifying that the bidder had in force insurance coverage with respect to the risks listed in the specifications and with the required amount of coverage.
The Borough reserved the right to reject a bid if the bidder failed to furnish any of the information or documents required by the specifications. The specifications further provided that an “award, if made, will be to the lowest responsible Bidder providing his bid complies in all respects with the requirements, as contained herein, of the Borough of Island Heights.” However, the Borough “reservefd] the right to waive, in its sole discretion, any minor informalities, defects or non-conformities in any bid documents submitted if it is determined to be in the best interest of the Borough of Island Heights to do so.”
The bids were opened on January 29, 1993, and Meadowbrook and defendant Consolidated Waste Services, Inc. (Consolidated) were the only bidders for the proposed contract. Consolidated’s bid for the three-year contract was $556,300, while Meadowbrook’s bid was $657,405. Consolidated’s bid, however, failed to include either a consent of surety or a Certificate of Insurance as required by the bid specifications. Consolidated’s bid also did not contain an adequate ownership-disclosure statement. Meadowbrook’s bid, however, complied in all respects with the bid specifications.
Consolidated delivered the required Certificate of Insurance to Borough officials approximately one-half hour after the opening of *312 bids. Four days later, on February 2, 1993, Consolidated provided the Borough with a consent of surety in the form of a letter from Acstar Insurance Company (Acstar) that stated: “In the event that Consolidated Waste Services, Inc. should be awarded the contract for the Borough of Island Heights project, ACSTAR Insurance Company as Surety, will furnish a Payment and Performance Bond providing Consolidated Waste Services, Inc. continues to meet ACSTAR Insurance Company’s underwriting and collateral requirements.” Consolidated furnished to the Borough an ownership-disclosure statement complying with the specifications on February 8, 1993.
Although Meadowbrook objected to the award of the contract to Consolidated because of its failure to provide a consent of surety and an adequate ownership-disclosure statement with its bid, the Borough’s governing body elected to waive those deficiencies and adopted a resolution awarding the contract to Consolidated.
Meadowbrook instituted this action challenging the validity of the resolution awarding the contract to Consolidated and seeking to compel the Borough to award the contract to Meadowbrook. The Law Division dismissed Meadowbrook’s complaint, determining that the submission of the incomplete ownership-disclosure statement was a nonmaterial defect that had been cured, and that Consolidated’s failure to submit a consent of surety with its bid had been cured by the furnishing of a consent of surety four days after the bid opening. The Law Division also concluded that the conditional terms of the consent of surety eventually furnished were commercially reasonable and therefore complied with the specifications.
On appeal, Meadowbrook again challenged Consolidated’s failure to submit the consent of surety with its bid, and its submission of the inadequate disclosure statement. The Appellate Division affirmed substantially for the reasons stated by the trial court. In its petition for certification, Meadowbrook raises only the issue of Consolidated’s failure to submit a consent of surety with its bid.

The competitive-bidding process is incorporated in the Local Public Contracts Law.
N.J.S.A
40A:ll-3 and -4 require that municipalities and counties advertise for bids on public contracts that exceed the statutory threshold amount. The purpose of the Local Public Contracts Law is to “secure for the public the benefits of unfettered competition.”

As a result, all bids must comply with the terms imposed, and any material departure invalidates a nonconforming bid as well as any contract based upon it.

Essentially this distinction between conditions that may or may not be waived stems from a recognition that there are certain requirements often incorporated in bidding specifications [that] by their nature may be relinquished without there being any possible frustration of the policies underlying competitive bidding. In sharp contrast, advertised conditions whose waiver is capable of becoming a vehicle for corruption or favoritism, or capable of encouraging improvidence or extrava- *315 ganee, or likely to affect the amount of any bid or to influence any potential bidder to refrain from bidding, or which are capable of affecting the ability of the contracting unit to make bid comparisons, are the kind of conditions [that] may not under any circumstances be waived.

“□first, whether the effect of a waiver would be to deprive the municipality of its assurance that the contract will be entered into, performed and guaranteed according to its specified requirements, and second, whether it is of such a nature that its waiver would adversely affect competitive bidding by placing a bidder in a position of advantage over other bidders or by otherwise undermining the necessary common standard of competition.!’]”
[Ibid, (quoting Palamar Constr., Inc. v. Township of Pennsauken, 196 N.J.Super. 241, 255,482 A.2d 174 (App.Div.1983) (quoting River Vale, supra, 127 N.J.Super. at 216,316 A.2d 737 )).]
Application of the River Vale criteria to the question whether a consent-of-surety requirement can be waived requires that we focus on the function of the consent of surety in the public-bidding process. The specifications state that the purpose of a performance bond from a surety is to guaranty that the contractor will “execute the work in accordance with the terms of the specifications and contract.” If the advertisements or specifications for a bid subject to the Local Public Contracts Law require a surety-company bond, then N.J.S.A. 40A:ll-22 mandates a consent of surety:
When a surety company bond is required in the advertisement or specifications for a contract or agreement, every contracting unit shall require from any bidder submitting a bid in accordance with plans, specifications and advertisements, as provided for by law, a certificate from a surety company stating that it will provide the contractor with a bond in such sum as is required in the advertisement or in the specifications.
*316
This certificate from a surety company, referred to as a consent of surety, assures the public entity that the surety will provide the performance bond if the contract is awarded to and signed by the bidder.
See L. Pucillo, supra,
73
N.J.
at 353,

The Borough and Consolidated contend that the omission of the consent of surety was immaterial and could be temporarily waived and subsequently cured. They assert that the effect of a waiver would not be to deprive the Borough of its assurance that the contract will be entered into, performed, and guaranteed in accordance with the specifications, noting that if Consolidated were to refuse to sign the contract, the Borough would retain the bid security. The trial court agreed, noting as well that the subsequent letter from Acstar “provides the municipality with the appropriate assurances that the contract would be entered into and it would be performed in accordance with the terms of' the contract.”
We hold that Consolidated’s failure to include a consent of surety with its bid proposal is a material defect that can be neither waived nor cured. Accordingly, to the extent that
Prismatic Development Corp., supra,
236
N.J.Super.
at 165,
*321 A consent of surety is a direct undertaking by the bonding company, enforceable by the municipality. Its purpose is to provide a guarantee to the municipality, at the time of the submission of bids, that if the bidder were to be awarded the contract, the surety would issue the required performance bond. The Borough’s bid specifications required that “[t]he party to whom this contract shall be awarded shall furnish a bond of any indemnity company * * * for the full amount of the bid.” The bid specifications also required, pursuant to N.J.S.A. 40A:ll-22, that all bidders include a consent of surety with their submission.
To permit waiver of the consent-of-surety requirement would undermine the stability of the public-bidding process. For example, if a low bidder that had failed to submit a consent of surety decided it no longer sought the contract because it had determined that its bid was too low, that bidder could decline to obtain the consent of surety and the performance bond. Without a performance bond, the bidder cannot be required to enter into and perform the contract.
See Hillside, supra,
25
N.J.
at 328,
In addition, a bidder who fails to submit a consent of surety with its bid proposal may be unable to obtain a consent of surety
*322
or a performance bond if it is later awarded the contract. In
Albanese v. Machetto,

N.J.Super.
605, 607,
The Legislature obviously regarded the financial capacity of a bidder to be a material and substantial consideration in the determination of the lowest responsible bidder, as evidenced by its adopting separate provisions within the Local Public Contracts Law to provide municipalities with a means of requiring prospective bidders to furnish in advance a statement of their financial capacity.

We are also persuaded that Consolidated’s failure to include a consent of surety with its bid submission had the capacity to affect
*323
the fairness of the bidding process. “This is so even though it is evident that in fact there was no corruption or any actual adverse effect upon the bidding process.”
Terminal Constr. Corp., supra,

N.J.

Our specific concern is that the requirement of a consent of surety “ ‘may have deterred others from bidding who would have bid had they known that [that] condition[ ] would be waived.’ ”
L. Pucillo, supra,

N.J.
at 358,
Other considerations also persuade us that to permit waiver of a consent-of-surety requirement could affect the fairness of the competitive-bidding process. A bidder’s ability to perform a project might improve between the time the bids are submitted and the time the bids are awarded, with the result that a surety initially unwilling to supply a bond might be willing to do so later. Furthermore, a bidder that is determined to be the low bidder on a project may be willing to invest additional capital and take other steps necessary to obtain the required consent of surety, which it would not have done without the assurance that it would then be awarded the contract. Moreover, by permitting a waiver of the eonsent-of-surety requirement, those bidders with limited bonding capacity would not need to deplete that capacity by obtaining the consent of surety, which would allow them simultaneously to submit bids for other contracts.
Courts should not casually “transform the mandatory requirement in these specifications [of including a consent of surety at the time the bid is submitted] into a polite request.”
L. Pucillo, supra,
73
N.J.
at 356,
We recognize that to prohibit the waiver of the consent-of-surety requirement occasionally may result in additional cost to the public, but we have no doubt that the overriding interest in insuring the integrity of the bidding process is more important than the isolated savings at stake. If an exception were made, its effect would be to encourage bidders not to provide consents of surety, a result contrary to the purpose of the Local Public Contracts Law.
Because we find that the Borough’s waiver of the consent-of-surety requirement was beyond its authority, the contract entered into between Consolidated and the Borough is void.
