7. �OR EQUAL� SUBMISSIONS. Where materials or equipment are specified by a trade or brand name, it is not the intention of the Owner to discriminate against an equal product of another manufacturer, but to set a definite standard of quality or performance. In preparing its proposal, each bidder is expected to include in its base Bid the cost of the item so specified. However, in certain Technical Specification sections, manufacturers are listed followed by �or equal�.

In those items where �or equal� is not included, it is hereby added and understood to be included, even though not specifically stated in each Technical Specification. If a bidder chooses to submit a suggested �or equal� product in lieu of a product by one of the named manufacturers, Owner will evaluate the item to determine if it is an �equal�. The bidder is responsible for providing all data required to evaluate an item submitted as a suggested �or equal.� Owner�s decision on whether a suggested manufacturer is an �equal� is final. No claims for additional cost or time delay, etc. will be accepted if a suggested manufacturer is submitted by bidder as an �equal� and Owner decides the item is not �equal�.

Bidder must submit its list of suggested �or equal� items at time of Bid submission. No additional suggested �or equal� items will be considered after bid opening.

8. MINIMUM UNIT PRICE ITEMS.

Instructions to Bidders April 2026

14. AWARD OF CONTRACT. Owner reserves the right to reject any or all Bids, including without limitation the right to reject any or all nonconforming, non-responsive, unbalanced or conditional Bids and to reject the Bid of any bidder if Owner believes that it would not be in the best interest of the Project to make award to that bidder, whether because the Bid is not responsive or the bidder is unqualified or of doubtful financial ability or fails to meet any other pertinent standard or criteria of Owner. Owner also reserves the right to waive all informalities and defects in bidding, except time of submitting a Bid.

Discrepancies between the multiplication of units and unit prices in a Bid will be resolved in favor of the unit prices. Discrepancies between the indicated sum of any column of figures and the correct sum thereof will be resolved in favor of the correct sum if the correct sum is evident from the face of the Bid.

In evaluating Bids, Owner will consider, among other things, the qualifications of bidders, whether the Bids comply with the prescribed requirements, and such substitutions, alternates, unit prices and other data, as may be requested in the bid form or prior to the notice of award. Alternate bid items will not be considered unless requested in the bid form.

Owner may consider the qualifications and experience of subcontractors, suppliers, and other persons and organizations proposed for the Work. Owner also may consider the operating costs, maintenance requirements, performance data and guarantees of major items of materials and equipment proposed for incorporation in the Work.

Owner may conduct such investigations as Owner deems necessary to assist in the evaluation of any Bid and to establish the responsibility, qualifications and financial ability of bidders, proposed subcontractors, suppliers and other persons and organizations to perform and furnish the Work in accordance with the Contract Documents, to Owner�s satisfaction.

BY SUBMITTING A BID, EACH BIDDER AUTHORIZES OWNER TO PERFORM ALL

INVESTIGATIONS INTO THE BIDDER�S BACKGROUND, CAPABILITIES, PRIOR

EXPERIENCE, AND OTHER FACTORS PERTAINING TO BIDDER�S PERFORMANCE OF THE

WORK, AS OWNER DEEMS NECESSARY IN ITS SOLE DISCRETION, AND FOR THAT

PURPOSE, SUBMISSION OF A BID ACTS AS BIDDER�S SPECIFIC AUTHORIZATION TO

PERSONS AND ENTITIES CONTACTED BY OWNER IN CONNECTION WITH SUCH

INVESTIGATIONS TO PROVIDE OWNER WITH THE INFORMATION REQUESTED BY OWNER

AND TO DISCUSS AND EXPRESS OPINIONS CONCERNING BIDDER. FURTHER, BY

SUBMISSION OF A BID, BIDDER AGREES TO FULLY AND FOREVER WAIVE AND RELEASE

ANY CLAIM (KNOWN OR UNKNOWN) IT HAS OR MAY HAVE AGAINST THE OWNER,

ENGINEER, DEVELOPER AND THEIR RESPECTIVE ATTORNEYS, EMPLOYEES,

CONSULTANTS, REPRESENTATIVES, AND AGENTS (�THE EVALUATING PARTIES�)

ARISING OUT OF OR IN CONNECTION WITH THE: (1) ADMINISTRATION, EVALUATION, OR

RECOMMENDATION (OR LACK THEREOF) OF ANY BID; (2) WAIVER OF ANY

REQUIREMENTS UNDER THE BID DOCUMENTS OR THE CONTRACT DOCUMENTS; AND (3)

ACCEPTANCE OR REJECTION OF ANY BIDS AND AWARD OF THE CONTRACT.

Owner reserves the right to award the Bid, at Owner�s discretion, based on the amount of the total base bid (without including �Extra Unit Price Items� or �alternate� bid items) or on the amount of the total amount bid (including �Extra Unit Price Items� or �alternate� bid items), or based on any other combination, means or method determined appropriate by Owner.

If the Contract is to be awarded, it will be awarded to the responsible bidder whose evaluation by Owner indicates that the award will be most advantageous to the Owner and result in the best and most economical completion of the Work.

Instructions to Bidders April 2026

If the Contract is to be awarded, Owner will give the successful bidder a notice of award within sixty (60) days after the day of the Bid opening.

15. TAXES, LICENSES AND FEES. Certain taxes, licenses, fees, and other similar items are part of the cost of the Work, and it is bidder�s responsibility to familiarize itself with these costs and to observe and comply with the Laws and Regulations relating to same. The prices, sums, rates, and other charges set forth in the bidder�s Bid must cover and include all such costs. Owner is exempt from Texas sales and use taxes pursuant to Texas Tax Code § 151.309 as a political subdivision of the State of Texas. Owner shall provide Contractor, if requested by Contractor in writing, with a completed Texas Sales and Use

Tax Exemption Certification as evidence of the applicability of such exemption, as limited by applicable statute.

18. INSURANCE. See section entitled �INSURANCE REQUIREMENTS� attached to and incorporated into the General Conditions of the Contract as Attachment A to the General Conditions of the Contract and Special Conditions of the Contract Part B, if attached..

19. SOILS REPORT. If a soils investigation has been made for this Project, the soils report and log of borings is available for bidder�s information only. The report is not a warranty of subsurface conditions, nor is it a part of the Contract Documents. Bidders are expected to examine the Site and such reports and then decide for themselves the soils or conditions that may be encountered.

Owner, Engineer, and Developer, if applicable, disclaim any responsibility for the accuracy, true location and extent of the surface and subsurface investigations that have been prepared by others. Owner, Engineer, and Developer, if applicable, further disclaim responsibility for interpretation of that data by bidder, e.g., projecting soil-bearing values, rock profiles, soil stability and the presence, level and extent of underground water or other underground facilities or utilities.

Instructions to Bidders April 2026

20. LABOR CLASSIFICATION AND MINIMUM WAGE SCALE.

(A) General: Chapter 2258 of the Texas Government Code provides that any political subdivision of the State of Texas shall determine the general prevailing wage rate received by the classes of workers employed on projects similar to this Project and shall specify in the call for bids and in the Contract Documents the minimum wage rates which must be paid for each type of worker. This statute further provides that the Contractor or subcontractors must pay, as penalty to Owner, Sixty Dollars ($60.00) for each worker employed for each calendar day or part of the day that the worker is paid less than the wage rates stipulated in the Contract. Owner is authorized to withhold from the Contractor the amount of this penalty from any payment due under the Contract Documents.

The statute likewise requires that the Contractor and subcontractors keep an accurate record of the names and occupations of all persons employed by them on the construction of the Project and to show the actual per diem wages paid to each worker. These records are open to the inspection of Owner.

(B) The minimum wage rates that apply to this Contract are specified in Attachment B to the General Conditions of the Contract. Contractor and subcontractors must review and ascertain such wage rates and pay at least such minimum rates.

21. ECONOMIC DISINCENTIVES. The Contractor and the Owner agree that time is of the essence of this Contract. The Contractor and the Owner agree that a breach of this Contract by failure to complete the Work in the specified time will cause harm to the Owner. Therefore, the

Contractor and the Owner agree that for each and every calendar day the Work or any portion thereof shall remain uncompleted after the expiration of the time limit(s) set in the Contract, or as extended under the provisions of these General Conditions (including, without limitation, due to a delay caused by Contractor�s failure to comply with the Contract Documents or due to Owner�s termination of Contractor for default under the Contract Documents), Contractor shall be liable to

Owner for economic disincentives under Section 49.271(e) of Texas Water Code, in the amount of

�NONE� for each such calendar day. The Owner shall have the option to deduct and withhold said amount from any monies that the Owner owes the Contractor or its sureties or to recover such amount from the Contractor or the sureties on the Contractor�s bond.
