1 of 7 APRIL 2026

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.

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 two (2) calendar days 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 each addendum is issued it becomes a part of the Contract Documents.

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 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.

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 five (5) percent 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.

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.

6. DELIVERY OF BIDS. It is each bidder’s responsibility to deliver its Bid and Bid Security as stated in the Invitation to Bidders before the closing time. The fact that a Bid and a Bid Security were dispatched will not be considered. The Bid and Bid Security must be timely delivered to be considered.

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

The apparent most qualified, responsible bidder must submit to Owner, with its Bid, either (i) a fully completed contractor’s statement of qualification or (ii) a written statement that the most recently submitted contractor’s statement of qualification is accurate, which statement of qualification must be considered in the award of the Contract.

The form of the Contractor’s statement of qualification is available from the Engineer. 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.
