INSTRUCTIONS TO BIDDERS

1. PREPARATION OF BIDS. Unless otherwise directed in the Invitation to Bidders, each Bid must be submitted on the bid forms provided or on photocopies of the forms, in conformity with the requirements of the Invitation to Bidders, these Instructions to Bidders (“Instructions”), and the instructions printed on the bid form. In addition, if submitting a paper Bid, the Bid must be submitted in duplicate.

All blanks on the bid form must be completed and no change shall be made to the bid form or any other of the Contract Documents. All amounts must be in figures, with amounts extended and totaled. If minimum unit prices have been established for certain items, the minimum unit prices will be shown on the bid form. See Paragraph 8 of these Instructions. If the bidder chooses not to bid on optional items (if any), “No Bid” must be entered in the bid space. Any Bid may be rejected if it contains any omission, erasure, alteration, addition, irregularity of any kind, or items not called for; if it does not submit prices for each of the items in the bid form; if it is not signed by the bidder; if it is unbalanced; or if it in any manner, fails to conform to the conditions of the Invitation to Bidders and these Instructions. An “unbalanced” Bid means a Bid containing unit prices that are significantly less than cost for some items and significantly more than cost for others. This may be evidenced by submission of unit price Bid items where the cost is significantly higher/lower than the cost of the same Bid items submitted by other Bidders on the same Project.

The bidder must sign its Bid. If the Bid is made by a partnership or corporation, the name and address of the partnership or corporation must be shown together with the names and addresses of the partners or officers. If the Bid is made by an individual, it must be executed by that person; if made by a partnership, it must be executed by one of the partners (and if by a limited partnership, then executed by the general partner); or if made by a corporation, it must be executed in the corporate name by the president or a vice-president (or other corporate officer accompanied by evidence of authority to sign) and the corporate seal must be affixed and attested by the secretary or assistant secretary of the corporation. The corporate address and state of incorporation shall be shown below the signature.

When applicable, evidence of authority to conduct business as an out-of-state corporation in the State of Texas must be provided in accordance with the paragraph entitled QUALIFICATION OF BIDDERS. State contractor license number, if any, must also be shown.

2. CONTRACT DOCUMENTS. The Contract Documents are complementary and must be read together as a whole; what is called for by one is binding as if called for by all.

Bidders desiring further information or further interpretation of any part of the Contract Documents are hereby obligated to submit a written request online to the www.civcastusa.com system for such information to Engineer not less than seventy-two hours (72 hours) before the Bid opening. If appropriate, answers to these requests will be given, in writing, to all bidders as addenda to the Contract Documents, and when

Instructions to Bidders II - 2 September 2025 each addendum is issued it becomes a part of the Contract Documents. No explanation or interpretation of the Contract Documents, other than written addenda, is binding.

It is the responsibility of each bidder to determine if it has received all addenda, complete files of which will be maintained at the Engineer’s office and the office designated to receive the Bids, if any.

Each bidder must inform itself fully of the construction and labor conditions under which the Work will be performed and will be presumed to have inspected the Site and to have read and to be thoroughly familiar with the Contract Documents. Failure to do so will not relieve the successful bidder of its obligation to furnish all materials and labor necessary to carry out the requirements of the Contract Documents and to complete the Work for the consideration in its Bid.

3. PRE-BID CONFERENCE. A MANDATORY pre-bid conference among Owner, Engineer, prospective bidders, and others will be held to discuss the scope of the Work and to answer questions concerning the Work. No addendum will be issued at this conference, but an addendum will be issued afterwards, if necessary, to answer questions. The MANDATORY pre-bid conference will be held at the place and time stated in the Invitation to Bidders or as modified by written addenda. Attendance by each prospective bidder or its representative at the pre-bid conference is MANDATORY, and no Bid will be opened unless the bidder or representative was present at the pre-bid conference. If an attendee fails to provide his/her name, firm represented, street address, and telephone number, Owner may treat such attendee as not having been present and as having failed to comply with the mandatory pre-bid conference requirement. No person can represent more than one bidder at the MANDATORY pre-bid conference. If a person claims to represent more than one bidder at the pre-bid conference, the Bid of each bidder so represented will be returned unopened.

4. BID SECURITY. Each Bid must be accompanied by a bid bond or a certified or cashier’s check, acceptable to the Owner, in an amount not less than two percent (2%) of the total amount bid (the “Bid Security”), as a guarantee that the successful bidder will enter into the Contract and execute the required Bonds on the forms provided and provide the required insurance certificates and Bonds within seven (7) days after the date Contract Documents are received by the successful bidder. Bid Securities will be returned to all but the three (3) most qualified, responsible bidders within three (3) days after opening of Bids, and the latter’s Bid Securities will be returned after complete execution of the Contract Documents. If the successful bidder does not enter into the Contract after notice of award, then the bidder’s Bid Security will be forfeited and will be retained by Owner. If the award of the Contract to the successful bidder is canceled or not executed for any reason, the Owner may accept the next lowest bid and proceed with the next-lowest qualified bidder.

5. BONDS. The successful bidder must furnish a performance bond, a payment bond, and a maintenance bond each in the sum of 100 percent (100%) of the Contract Price The Bonds must be in the form prescribed by the Contract Documents except as required otherwise by Laws and Regulations.

All Bonds signed by an agent must be accompanied by a certified copy of the agent’s authority to act. The Bonds must be executed by a duly appointed representative of the surety company licensed by the State of Texas as a General Lines Agent and such licensing must be recorded in the files of the Texas Department of Insurance. If the surety company does not have such a rating due to the length of time it has existed, the surety company must be eligible to participate in the surety bond guarantee program of the Small Business Administration and must be an approved surety listed in the current U.S. Department of Treasury Circular 570, and must meet all of the rules and regulations of the Treasury Department with respect to performance and payment bonds for federal jobs, including specifically the rules related to underwriting limitation.

If bidder’s proposed surety company, agency or agents do not meet the requirements herein, then Owner may refrain from considering the bidder for Contract award and Owner may require bidder to forfeit its Bid Security.

It is further agreed that the successful bidder will execute the Bonds required for the satisfactory performance of the Work, the fulfillment of any guarantees required, and the prompt payment to all persons supplying labor and materials in the prosecution of the Work, in accordance with the Contract Documents and on the forms provided for this purpose. It is agreed that this Contract is not in effect until the required Bonds are furnished and approved by Owner. Upon increase of the Contract Price authorized by Change Order, Contractor must immediately provide revised Bonds for such increased Contract Price. Contractor’s failure to provide compliant Bonds may be grounds for immediate termination regardless of whether the Contractor has started the Work on the Project.

Instructions to Bidders II - 4 September 2025

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 certain other Technical Specification sections, manufacturers are listed with “or equal” not included. 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. If the approximate quantity and a minimum unit price have been established for items in the bid form, the bidder may not bid a unit price less than the minimum value; however, it may bid an amount greater than the minimum unit price. If no entry is made in the spaces provided, the minimum unit prices shown apply.

9. EXTRA UNIT PRICE ITEMS. Extra Unit Price Items are included to facilitate payment for changes and alterations that may be required to complete the Work. The Work, as provided by the Contract Documents, is described in bid items other than Extra Unit Price Items. When additional Work covered by Extra Unit Price Items is performed, payment will be based on the quantity constructed and the unit prices entered in the Bid.

10. TIME FOR COMPLETION. Contractor will not be allowed time extensions (i) due to inclement weather except for Force Majeure events as defined under Section 1.01 of the General Conditions of the Contract; (ii) due to non-availability of equipment or material, when the principal units of Work and tasks on the critical path are not in progress or are not delayed by the event of delay, interference, disruption, or hindrance;

(iii) when at least seven (7) hours of available working time remain out of the working day; (iv) while materials are drying and it is possible for the Contractor to enclose the area and use drying devices; (v) when an event of delay, interference, disruption, or hindrance occurs on a day other than a working day or other day when the Contractor had not originally planned to work; (vi) when an event of delay, interference, disruption, or hindrance occurs after the expiration of the Contract Time; (vii) to the extent the Contractor could have anticipated or alleviated the impact of the event of delay, interference, disruption, or hindrance through reasonable efforts; (viii) when events of concurrent delay overlap the claimed delay; and/or (ix) when an extension of time is precluded by any provision of the Contract Documents.

Owner may reject, at Owner’s sole discretion, a bidder’s statement of qualification if the bidder’s statement of qualification is not on the form provided.

12. MODIFICATION AND WITHDRAWAL OF BIDS.

Owner also reserves the right to waive all informalities and defects in bidding, except time of submitting a Bid.
