3.14. PROPOSAL OPENING AND AWARD OF CONTRACT

Proposals will be kept unopened until the time stated for opening of proposals. At such time, the contents of the proposal will be made public.

If award is made, it will be based on the lowest responsive, responsible bid whose base bid is the lowest.

The right is reserved, as the interest of WCW may require, to reject any or all proposals and to waive any informality in proposals received.

Within sixty (60) days after the time of opening of the bids, WCW will act either to accept a bid, to reject all bids or with the consent of the bidders and their sureties to extend the time in which WCW may act.

The acceptance of a bid will be evidenced by a Notice of Award of Contract in writing, delivered in person or by certified mail to the bidder whose bid is accepted.

Award of the Contract. Time is of the essence in this regard. After execution by the owner, one copy of the Agreement shall be returned to Contractor.

The failure of any bidder to whom WCW may award the Contract, as aforesaid to sign and return to

WCW, the Contract together with the required Performance Bond, Payment Bond, and insurance certificates and endorsements the specified time period, shall entitle WCW to declare a breach of

Contract by such bidder, to award the Contract to another bidder in accordance with the provisions of the Contract Documents, and to declare a forfeiture of the bidder's proposal security accompanying its proposal.

In the event of such failure, WCW will suffer damage, the amount of which is difficult, if not impossible, to ascertain, and WCW shall therefore be entitled to retain the amount of such cashier or certified check, submitted by the bidder as proposal security, or to enforce the provisions of the Bidder's Bond in the amount thereof, as liquidated damages for such breach of Contract, as provided by applicable law.

3.16. BONDS AND INSURANCE POLICIES

The bidder to whom the contract award is made shall, at the time of execution of the Contract, furnish to WCW a Performance Bond and a Payment Bond, executed as surety by a corporation acceptable to

The entire cost of these bonds shall be borne by the successful bidder.

If the surety on any bond furnished by the Contractor is declared bankrupt, or becomes insolvent, or its right to do business is terminated, or it ceases to meet the requirements of the above paragraph, the

Contractor shall, within five (5) calendar days thereafter, notify WCW and substitute another bond and surety, both of which must be acceptable to WCW.

3.17. NONDISCRIMINATION IN EMPLOYMENT

Contracts for work under this Proposal will obligate the Contractor and subcontractors not to discriminate in employment practices.

Within ten (10) calendar days after receipt of any such written determination, the Contractor may file a written protest with the Engineer stating clearly and in detail the Contractor's objections, the reasons therefor, and the nature and amount of additional compensation or extension of time, if any, to which the Contractor contends it will be entitled thereby. The Contractor shall proceed to perform the work that the

7.6. INTENT OF THE CONTRACT

A. A. It is the intent that all obligations of WCW and the Contractor are fully set forth and described in the Contract. All parts of the Contract are intended to be correlative and complementary, and any work required by one part and not mentioned in another part shall be performed to the same extent and purpose as though required by all parts.

B. The organization of the Contract Documents into sections, parts, and subsections and the arrangement of the contract plans shall not necessarily control the Contractor in dividing any work among any of its subcontractors or in establishing the extent of work to be performed by any trade or craft. The headings or titles of any article, section, subsection, paragraph, provision, or part of the Contract shall not be deemed to limit or restrict the content, meaning, or effect of such article, section, subsection, paragraph, provision, or part. Titles assigned to the various sections and subsections do not necessarily limit the scope of topic, but are assigned solely to designate a central theme which may be further addressed by either volumes, parts, sections, or subsections for particular applications. Absence of reference in any one to other such sections, parts, or subsections shall not in any way serve to waive the requirements otherwise applicable to the work in its entirety. All sections of the Specifications and Project Drawings are interdependent and applicable to the Project as a whole.

C. Where the words "as shown," "as detailed," "as indicated," or words of like import are used in the Contract, reference is to the Project Drawings unless the context clearly indicates a different meaning. Where the words "required," "approved," "determined," "acceptable," "favorably reviewed," "reviewed," "selected," "directed," "equivalent," "equal," "satisfactory," or words of like import are used in the Contract, action by the Engineer or WCW is indicated unless the context indicates otherwise, and all work shall be in accordance therewith. Such action, or failure to act, shall not relieve the Contractor of its contractual responsibilities for performance of the Contract.

D. The Contractor shall perform the work in accordance with the terms of the Contract. The

Specifications and all notes on the Project Drawings are directed to the Contractor and all work shall be performed by it even though phrases such as "the Contractor shall" or "shall be done by the Contractor" are omitted. Where portions of the work are described in general terms, but not in complete detail, the Contractor shall perform the work utilizing skilled trade persons and high quality material. Unless otherwise specified such as deep excavation/shoring, traffic control, or detail design where a registered professional engineer shall be required, the Contractor shall furnish all labor, materials, tools, equipment, and incidentals and do all the work involved in executing the Contract in a timely, satisfactory, and workmanlike manner.

E. The misplacement, addition, or omission of a word or character shall not change the intent of any part of the Contract from that set forth by the Contract as a whole.

F. For the sake of convenience, the masculine/feminine pronoun may be used to designate who performs the work and for other purposes and, in all cases, applies equally to all persons.

Moreover, the word "Contractor" as used in the Contract, applies to the General Contractor. If the Contractor is a partnership or joint venture then for the purpose of the Contract, the members of the partnership or joint venture shall be jointly and severally liable notwithstanding any agreement as between themselves to the contrary.
