Each bid proposal shall be accompanied by a certified or cashier's check or a proposal guaranty bond payable to the order of the West Bay Sanitary District in an amount not less than ten percent (10%) of the amount of the bid as a guaranty that the bidder will execute the contract if it be awarded to him/her in conformity with the proposal.

The District ("Owner") reserves the right to reject any or all bids and to determine which proposal is, in the judgment of the District, the lowest responsible bid of a responsible bidder or group of bidders and which proposal should be accepted in the best interest of the District. The District also reserves the right to waive any informalities in any proposal or bid.

Bid proposals received after the time announced for the opening will not be considered. No bidder may withdraw his proposal after the time announced for the opening, or before award and execution of the contract, unless the award is delayed for a period exceeding forty-five (45) days.

Pursuant to the provisions of Public Contract Code Section 22300, and upon the request and at the expense of the Contractor, securities equivalent to the amount withheld by the District to ensure performance under the Contract may be deposited with the District, or with a state or federally chartered bank as escrow agent who shall deliver such securities to the Contractor upon satisfactory completion of the contract. Only those securities listed in Government Code Section 16430 or other securities approved by the District are eligible for deposit. The deposit of securities with an escrow agent or the District shall be made in the form and on such terms and conditions as the District may require to protect the interest of the District in the event of the Contractor's default. The Contractor shall be the beneficial owner of any securities that are deposited and shall receive any interest thereon.

Pertaining to Sections 1770, 1773, and 1773.1 of the California Labor Code the successful bidder shall pay not less than the prevailing rate of per diem wages as determined by the Director of the California Department of Industrial Relations.

SECTION A2 - INFORMATION FOR BIDDERS

2.01 INSPECTION OF SITE OF WORK

Bidders are required to inspect the site of the work in order to satisfy themselves by personal examination or by such means as they may prefer, of the location of the proposed work and of the actual conditions of the site of work. If, during the course of his examination, a bidder finds facts or conditions that appear confusing to him, he may apply to the District for additional information and explanation before submitting his bid.

However, no such supplemental information requested or furnished shall vary the terms of the specifications or the Contractor's sole responsibility to satisfy himself as to the conditions of the work to be performed.

The submission of a proposal by the bidder shall constitute the acknowledgment that, if awarded the contract, he has relied and is relying on his own examination of (a) the site of the work, (b) the access to the site, and

(c) all other data, matters, and things requisite to the fulfillment of the work and on his own knowledge of existing services and utilities on and in the vicinity of the site of the work to be constructed under the contract, and not on any representation or warranty of the District. No claim for additional compensation will be allowed which is based upon a lack of knowledge of the above items.

2.02 EXAMINATION OF CONTRACT DOCUMENTS

Each bidder shall thoroughly examine and be familiar with legal and procedural documents, general conditions, specifications, drawings and addenda (if any). The submission of a proposal shall constitute an acknowledgment upon which the District may rely that the bidder has thoroughly examined and is familiar with the contract documents. The failure or neglect of a bidder to receive or examine any of the contract documents shall in no way relieve him from any obligation with respect to his proposal or to the contract. No claim for additional compensation will be allowed which is based upon a lack of knowledge of any contract documents.

2.03 INTERPRETATION OF CONTRACT DOCUMENTS

No oral representation or interpretations will be made to any bidder as to the meaning of the contract documents. Requests for an interpretation shall be made in writing and delivered to the District at least 10 days before the time announced for opening of the proposals. Interpretations by the District will be in the form of an addendum to the contract documents and, when issued, will be sent as promptly as is practical to all parties to whom the bid documents have been issued. All such addenda shall become part of the contract.

2.04 SUBSURFACE SOIL DATA

No sub-surface soil investigations were made for this project.

2.05 PROPOSAL

Proposals shall be made on the blank forms prepared by the District without removal from the bound contract documents. All proposals shall give the total price proposed, both in writing and in figures, shall give all other information requested herein, and shall be signed by the bidder or his authorized representative, with his address. If the proposal is made by an individual, his name, signature and post office address must be shown; if made by a firm or partnership, the name and post office address of the firm or partnership and the signature of at least one of the general partners must be shown; if made by a corporation, the proposal shall show the name of the state under the laws of which the corporation is chartered, the name and post office address of the corporation, and the title of the person who signs on behalf of the corporation. If the proposal is made by the corporation, a copy of the bylaws or resolution of the board of directors of the corporation shall be furnished showing the authority of the office signing the proposal to execute contracts on behalf of the

A5 PART A

corporation.

Each proposal shall be enclosed in a sealed envelope, labeled as specified in the Advertisement. Bidders are warned against making erasures or alterations of any kind, and proposals which contain omissions, erasures or irregularities of any kind may be rejected. No oral, telegraphic or telephonic proposals or modifications will be considered.

2.06 ADDENDA

Each proposal shall include specific acknowledgement in the space provided of receipt of all addenda issued during the bidding period. Failure to so acknowledge may result in the proposal being rejected as non-responsive.

2.07 BID PRICE

The bid price for work as described in Article A3.02 - Bidding Schedule and/or other parts of the Contract Documents shall include all work described in any part of the Contract Documents that apply unless otherwise specifically provided for.

The bid price in Article A3.02 - Bidding Schedule and for other parts of the Contract Documents shall include everything necessary for the completion of construction and fulfillment of the contract including but not limited to furnishing all materials, equipment, tools, plant and other facilities and all management superintendence, labor and services for that option, except as specifically provided otherwise in the contract documents. Any work or material not specifically described on the bidding schedule and associated with the bidding option shall be performed or supplied as incidental work.

In the event of a difference between a price quoted in words and a price quoted in figures for the same quotation, the words shall be the amount bid. In the event that a product of a unit price and an estimated quantity does not equal the extended amount quoted, the unit price shall govern and the corrected product of the unit price and the estimated quantity shall be deemed to be the amount bid. If the sum of two or more items in a bidding schedule does not equal the total amounts quoted, the individual item amounts shall govern and the corrected total shall be deemed to the amount bid.

2.08 TAXES

Bid prices shall include allowance for all federal, state and local taxes.

2.09 VARIATIONS

By the submission of the bid proposal, it will be assumed by the District that the bidder has accepted without reservation or amendment the whole of the contract documents. However, a bidder may submit a proposal which is conditional upon such qualifications of or amendments to the contract documents as do not, in the sole discretion of the District materially alter the terms of the contract documents. The qualifications or amendments shall be fully described on the proposal. The District reserves the right to accept or reject any such entire bid containing the same or to consider price variations therefore (if any) in determining the lowest responsible bid.

2.10 QUALIFICATION OF BIDDERS

Each bidder shall be skilled and regularly engaged in the general class type of work called for under the contract. A statement setting forth his experience shall be submitted by each bidder on the form provided herewith. The General Contractor, or sub-contractor performing the work shall be competent in performing

A6 PART A

such type of work and shall demonstrate his competency and ability to perform such work by submitting sufficient documentation of prior similar projects and experiences and/or other information and data that, in the opinion of the District, constitutes sufficient evidence of the ability of the contractor or sub-contractor to perform and complete the same nature and magnitude of work by the method requested by the District for this project. In addition, a statement setting forth the experience, knowledge, and ability of the personnel available for employment in responsible charge of the work shall be submitted by each bidder on the form provided herewith. Failure to submit satisfactory evidence of competency to perform the work is sufficient cause for the District to determine the submitted bid unresponsive, which prevents award of the contract to the Contractor.

Each bidder shall possess either a Class A license or a combination of the Class C licenses as indicated in Article B8.0l - License Requirement. A copy of the Contractor's license(s) shall be submitted with the bid.

It is the intention of the District to award a contract to the bidder who furnishes satisfactory evidence that he has the requisite experience and ability and that he has sufficient capital, facilities and plant to enable him to prosecute the work successfully and properly, and to complete it within the time named in the contract.

To determine the degree of responsibility to be credited to the bidder, the District will consider previous work relationships and cooperation with the District and will also weigh any evidence that the bidder or personnel available for employment in responsible charge of the work has performed satisfactorily other contracts of like nature, magnitude and comparable difficulty and comparable rates of progress.

All contractors and subcontractors must register with the Department of Industrial Relations (DIR) prior to bidding on or performing any work for this project. Registration is valid for one fiscal year. Contractors who are debarred from performing state or federal public works are not eligible for registration; thus not eligible for bidding on this project. Contractors and subcontractors who fail to register prior to submitting a bid or performing any public work are subject to a penalty registration per DIR regulations. Each company or entity only needs to be registered once even if the company holds multiple licenses.

2.11 LIST OF SUBCONTRACTORS

Each proposal shall have listed on the form provided herewith the name and address of each subcontractor to whom the bidder proposes to sublet portions of the work in excess of one-half of one percent of the total amount of his bid. For the purpose of this paragraph, a subcontractor is defined as one who contracts with the contractor to furnish materials and labor, or labor only for the performance of work at the site of the work.

Contractor shall use only those subcontractors on the list, unless he receives prior written approval by District to substitute a subcontractor. As noted in Section 2.10, subcontractors must be registered with the DIR.

2.12 PROPOSAL GUARANTY

The proposal shall be accompanied by a proposal guaranty bond duly completed on the form found in Section A-4 of these contract specifications, by a corporation which is listed in the latest form 356 of the United States treasury Department as being acceptable as surety on Federal bonds and is duly licensed and admitted by the State of California to be a surety insurer in the State, in the sum of at least 10 percent of the total bid amount as described in the bidding schedule and/or other parts of the Contract Documents; or alternatively there is attached a certified or cashier's check, payable to the District in the sum of at least 10 percent of the total bid amount.

The amount payable to the District under the proposal guaranty bond, or the certified or the cashier's check and the amount thereof, as the case may be, shall be forfeited to the District as liquidated damages in case of a failure or neglect of the bidder to furnish, execute and deliver to the District the required performance bond, A7 PART A labor and material bond, evidences of insurance, and to enter into, execute and deliver to the District the agreement on the form provided herewith, within 10 days after being notified in writing by the District that the award has been made and the agreement is ready for execution.

2.13 MODIFICATION OF PROPOSAL

A modification of a proposal already received will be considered only if the modification is received prior to the time announced for the opening of bid proposals. All modifications shall be made in writing, executed and submitted in the same form and manner as the original proposal.

2.14 POSTPONEMENT OF OPENING

The District reserves the right to postpone the date and time for opening of proposals at any time prior to the date and time announced in the advertisement.

2.15 DISQUALIFICATION OF BIDDER

If there is reason to believe that collusion exists among the bidders, none of the bids of the participants in such collusion will be considered and the District may likewise elect to reject all bids received. All bidders are required to execute a non-collusion affidavit pursuant to Public Contract Code 7106 in the form shown in Section A3.04 – Non-collusion Affidavit and submit it with his/her bid.
