Any written modification so received will be read aloud at the time and place fixed for opening and reading of bids.

Written communication should not reveal the Bid price but should state the addition or subtraction or other modification so that the final prices or terms will not be known by the OWNER until the sealed bid is opened.

6) Interpretation and Addenda: No oral representation or interpretations will be made to any bidders as to the meaning of the Contract Documents. All questions about the meaning or intent of the Contract Documents are to be directed to the engineer. Additions, deletions, Sweet Springs GW Monitoring Wells ITB - Page 2 of 10 June 2026 or revisions to the Contract Documents considered necessary by the engineer in response to such questions will be issued by Addenda mailed or delivered to all parties recorded by the engineer or District as having received the Contract Documents. Questions received less than 14 days prior to the date of Bid opening may not be answered. Only answers to such questions issued by formal written Addenda will be binding. Oral and other interpretations or clarifications will be without legal effect.

Addenda may also be used to make other additions, deletions, or revisions to the Contract

Documents.

Bidders shall make no special interpretation or inference of intent from differing formats in the Technical Specifications.

7) Bidder’s Examination of Contract Documents and Site:

A. It is the responsibility of the Bidders to inspect the site of the work in order to satisfy themselves, by personal examination or by such other means as they may prefer, of the location of the proposed work and the actual conditions of and at the site. Bidders may apply to the Engineer for additional information and explanation before submitting bids. However, no supplemental information requested or furnished shall vary the terms of the Contract Documents or affect the Contractor’s sole responsibility to satisfy himself as to the conditions of the work to be performed. No claim for additional compensation will be allowed which is based upon a lack of knowledge of the actual conditions or location of the Work.

Submission of a proposal by the bidder shall constitute acknowledgment that, if awarded the contract, the bidder has relied and is relying on their own examination of (a) the site of the work; (b) access to the site; and (c) all other data, matters, and things requisite to the fulfillment of the work and, on their own knowledge of existing facilities 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 lack of knowledge of the above items. Removal, relocation, or protection of existing public utilities not identified by the District shall be done in conformance with Section 4215 of the Government Code.

B. Each bidder shall thoroughly examine and be familiar with legal and procedural documents, general conditions, specifications, drawings and addenda (if any).

Submission of a proposal shall constitute acknowledgment, upon which the Owner may rely, that the bidder has thoroughly examined and is familiar with the Contract Documents. Failure or neglect of a bidder to receive or examine any of the Contract Documents shall in no way relieve them of any obligation with respect to their 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.

C. Each bidder shall review the Plans and Specifications, prior to the submission of the bid, and report any errors and omissions noted by the Contractor to the Engineer. The review by the Contractor shall be confined to the Contractor’s capacity as a contractor, and not as a licensed design professional.

Sweet Springs GW Monitoring Wells ITB - Page 3 of 10 June 2026

8) OWNER Investigations and Testings:

A. Where the engineer has made investigations of surface and subsurface conditions in areas where work is to be performed under the contract, or in other areas, some of which may constitute possible local material sources, such investigations were made only for the purpose of study and design. Where such investigations have been made, bidders or contractor may, upon written request, inspect the records of the engineer as to such investigations subject to and upon the conditions hereinafter set forth. Such inspection of records may be made at the office of the engineer.

The records of such investigations are not a part of the contract and are made available for inspection solely for the convenience of the bidder or contractor. It is expressly understood and agreed by bidder or contractor that neither the OWNER nor the engineer assumes any responsibility whatsoever with respect to the sufficiency or accuracy of the investigations thus made, the records thereof, or of the interpretation set forth therein or made by the engineer in his use thereof and there is no representation, warranty or guarantee, either express or implied, that the conditions indicated by such investigations or records thereof are correct or representative of those existing throughout such areas or any part thereof, or that unanticipated developments may not occur or that materials other than, or in proportions different from, those indicated may not be encountered.

B. Where a log of test borings or other investigations of subsurface conditions have been made by the OWNER in respect to foundation or other structural design, and that information is shown in the plans, said information represents only the statement by the OWNER as to the character of material which has been actually encountered by it in its investigation, and is only included for the convenience of bidders. Water levels that may be shown on a log of test borings are valid on for the stated date of observation. The water level may change from season to season and from year to year. Investigations of subsurface conditions are made for the purpose of design, and the OWNER assumes no responsibility whatever in respect to the sufficiency or accuracy of borings or of the log of test borings or other preliminary investigations, or of the interpretation thereof, and there is no guaranty, either expressed or implied, that the conditions indicated are representative of those existing throughout the work, or any part of it, or that unobserved or unanticipated developments may not occur. Making such information available to bidders is not to be construed in any way as waiver of the provisions of this section and bidders must satisfy themselves through their own investigations as to conditions to be encountered.

C. The availability or use of information described in these Instructions to Bidders and other bid documents shall not be construed in any way as a waiver of the provisions of the Instructions of Bidders and a Bidder or Contractor is cautioned to make such an investigation and examination as it deems necessary to satisfy itself as to conditions to be encountered in the performance of the work and, with respect to possible local material sources, the quality and quantity of material available from such property and the type and extent of processing that may be required in order to produce material conforming to the requirements of the Specifications.

Sweet Springs GW Monitoring Wells ITB - Page 4 of 10 June 2026

D. No information derived from such inspection of records of investigations or compilations thereof made by Engineer, will in any way relieve the bidder or contractor from any risk or from properly fulfilling the terms of the contract.

E. Information derived from inspection of topographic maps, or from Plans showing location of utilities and structures will not in any way relieve the contractor from any risk, or from properly examining the site and making such additional investigations as it may elect, or from properly fulfilling all the terms of the contract.

9) Addenda or Bulletins: Any addenda or bulletins issued during the time of bidding shall form a part of the Contract Documents and Specifications, shall be covered in the proposal, and shall be made part of the Contract. Receipt of addenda must be acknowledged in the appropriate space on the Proposal Form. Failure to acknowledge all such addenda will be cause to reject the bid as being non-responsive. It is the Bidder’s responsibility to determine whether any addenda or bulletins have been issued.

10) Preparation of the Proposal: All blank spaces in the Proposal Forms, Contract

Documents, and Bid Schedule shall be properly filled in. The phrasing of the proposal shall not be changed and no additions shall be made to the items mentioned therein.

Unauthorized conditions, limitations, or provisions attached to a proposal will render it invalid and may cause its rejection. Alterations by erasure or inter-lineation must be explained or noted in the proposal over the signature of the bidder. Alternative proposals will not be considered unless specifically provided for in the Bid Schedule.

A Bidder may withdraw his/her proposal before the time fixed for opening of bids, without prejudice to himself, by submitting a written request to the OWNER for its withdrawal, and his proposal will be returned to him unopened when reached in the procedure of opening bids. No proposal may be withdrawn after the hour fixed for opening bids without rendering the accompanying certified or cashier's check or bidder's bond subject to forfeiture as liquidated damages in like manner as in the case of failure to execute the Contract after award, as provided hereinafter.

No proposal received after the time named or at any place other than the place stated in the Notice to Bidders will be considered. All proposals will be opened and declared publicly. Bidders, their representatives, and others interested are invited to be present at the opening. The OWNER reserves the right to waive any minor irregularities in any proposal, to reject any or all proposals, to reject one part of a proposal and accept the other, except to the extent that bids are qualified by specific limitations, and to make award to the apparent lowest responsible bidder for a period of 60 calendar days from the receipt of the award of bid. No proposal can be withdrawn for a period of 60 calendar days from the date of award of the bid, unless otherwise required by law. Where bonds are required, the bidder shall name in his/her bid the surety or sureties who have agreed to furnish said bonds.

11) Licensing of Contractors: Before submitting bids, Contractors shall be licensed in accordance with the provisions of Chapter 9, Division 3, of the Business and Professions Code of the State of California.

A photocopy of the appropriate license(s) shall be submitted with the proposal.

Sweet Springs GW Monitoring Wells ITB - Page 5 of 10 June 2026

In accordance with California Labor Code Section 1725.5, Contractors and Subcontractors (as defined by California Labor Code Section 1722.1) bidding on Public Works contracts in California shall be registered with the Department of Industrial Relations prior to bidding.

Proof of registration with the DIR will be required prior to award of any public works contract.

12) List of Subcontractors Filed With Bid: Each proposal shall have listed on the forms provided, 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 the proposal. For the purpose of this paragraph, a subcontractor is defined as anyone who contracts with the Contractor to furnish materials and labor, labor only, and/or one who specially fabricates and/or installs a portion of the work or improvement according to detailed drawings contained in the Contract Documents. All listings and subsequent substitutions, if any, shall be done in conformance with the Subletting and Subcontracting Fair Practices Act, Public Contract Code Section 4100 et seq.

I. The Contractor shall perform with its own organization work amounting to not less than 50 percent of the original total contract price, except that any work designated “Specialty Items” may be performed by subcontract and the amount of any such “Specialty Items” so performed may be deducted from the original total contract price before computing the amount of work required to be performed by the Contractor with its own organization.

When items of work in the Bid schedule are preceded by the letter (S), such items shall be deemed designated “Specialty Items.” Where an entire item is subcontracted, the value of work subcontracted will be based on the contract item bid price. When a portion of an item is subcontracted, the value of work subcontracted will be based on the estimated percentage of the contract item bid price, determined from information submitted by the Contractor, subject to approval by the Engineer.

13) Submission of Bids: All Bids must be submitted not later than the time prescribed, at the place and in the manner set forth in the Invitation to Bid. The OWNER shall not consider any Bid received after the time fixed or received at any place other than the place stated in the Invitation to Bid. Bids must be made on the prescribed Bid forms. A complete Bid requires submission of fully completed and executed: Bid, Designation of Subcontractors (if applicable), Bid Bond (or other bid guarantee), Experience Qualifications and Noncollusion Declaration. Each Bid must be submitted in a sealed envelope, so marked as to indicate its contents without being opened, and addressed in conformance with the instructions in the Notice Inviting Bids. The bidder is wholly responsible to see that its Bid is submitted at the time and place named for the opening of bids.

Bids shall acknowledge receipt of all addenda (identified by addendum no.) issued during the bidding period. Failure to acknowledge an addendum or clarification may result in the Bid being rejected as not responsive.

Bids shall be open at the time and place specified in the Notice Inviting Bids, unless changed by addendum. All Bids will be opened and read publicly. Bidders, their representatives and other interested parties, are invited to be present at the opening.

13a) Discrepancy in Bids: In the event of discrepancy between unit prices and totals, unit prices will prevail. [In case of discrepancy between words and figures, words will prevail.]

14) Bidders Interested in More Than One Bid: No person, firm, or corporation shall make, file, or be interested in more than one proposal for the same work unless alternate bids are

Sweet Springs GW Monitoring Wells ITB - Page 6 of 10 June 2026 specifically requested. A person, firm, or corporation who has submitted a sub-proposal to a bidder, or who has quoted prices of materials to a bidder, is not hereby disqualified from submitting a sub-proposal or quoting prices to other bidders.

15) Additive Bid Items: If additive bid items are called for, the Contract may be awarded at the election of the Governing Board to the lowest responsible bidder on the base bid, or on the base bid and any additive or combination of additives.

16) Award of Contract: Award of the contract, if awarded, will be made to the lowest responsive, responsible Bidder who’s Bid complies with the requirements of the Contract Documents. Unless otherwise specified, any such award will be made within the period stated in the Notice Inviting Bids that the bids are to remain open. Unless otherwise indicated, a single award will be made for all the Bid items in an individual Bid Schedule.

In the event the work is contained in more than one Bid Schedule, the owner may award Schedules individually or in combination. In the case of two or more Bid Schedules which are alternative to each other, only one of such alternative schedules will be awarded.

2) Before a Bid is considered for award, the OWNER may, in addition to the Experience Qualifications form, require a Bidder to submit a statement of facts and detail as to his business, technical organization and financial resources and equipment available and to be used in performing the work. Additionally, the OWNER may require evidence that the Bidder has performed other work of comparable magnitude and type. The OWNER expressly reserves the right to reject any Bid if it determines that the business and technical organization, equipment, financial and other resources or other experience of the Bidder (including the Bidder's subcontractors) is not sufficiently qualified for the work bid upon and, therefore, justifies such rejection.

17) Return of Bid Security: Within 14 days after award of the contract, the owner will, if requested, return the Bid securities accompanying such Bids that are not being considered in making the award. All other Bid securities will be held until the Agreement has been finally executed. They will then be returned, if requested, to the respective Bidders who’s Bids they accompany.

18) Lowest Responsible Bidder: In selecting the lowest responsible bidder, consideration will be given to the general competency of the bidder for the performance of the work covered by the bid. To receive favorable consideration, a bidder will be required to present evidence that he/she has successfully performed similar work of comparable magnitude or submit other evidence satisfactory to the OWNER that Bidder or his/her associates are personally competent to manage the proposed undertaking and to carry it forward to a successful conclusion. Professional integrity and honesty of purpose shall be essential requirements.

19) Local Conditions: Bidders shall read the Specifications, examine the reference drawings, inspect the project site, and make their own estimates of the existing facilities and the difficulties which will attend the execution of the work called for by the proposed contract, including local conditions, uncertainty of weather, project difficulty, and all other contingencies.

Bidders shall satisfy themselves by personal examination of the location of the proposed Work, and by such other means as they may choose as to actual conditions, actual quantities, and requirements and as to the accuracy of the quantities stated in the Bid Schedule. Information derived from the maps, plans, Specifications, profiles, or drawings, or from the Engineer or his/her assistants, shall not relieve the Bidder of this responsibility.

Sweet Springs GW Monitoring Wells ITB - Page 7 of 10 June 2026

Bidders shall not at any time after the submittal of a bid make or have any claim for damages or anticipated profits or loss of profit or otherwise because of any difference between the quantities of work actually done and material furnished and the unit price stated in the Bid Schedule. Bidders are encouraged to attend a pre-bid conference at the date, time, and location specified in the Notice Inviting Bids.

20) Substitution of Materials: All materials are mentioned as standards. Should a Contractor desire to substitute materials or methods for those specified, he shall state on a separate sheet attached to his bid the price deduction he will make if such a substitution is accepted in material and/or method. Such substitution submittal, however, may not be used in the determination of the lowest qualified bidder. Question of all such substitution shall be determined prior to the award of the Contract, as no substitution will be permitted after the Contract is signed unless approved in writing by the Engineer.

21) Payments: Payments to the Contractor on account of the Contract shall be made in accordance with the terms set forth in Article 1.7, Section 20104.5 of the State Public Contract Code, General Conditions and Supplementary General Conditions.

22) Execution of Contract: The apparent successful bidder shall execute a written Contract on the Form of Agreement attached hereto, secure the payment of workmen's compensation, furnish good and approved bonds, and proof of specified insurance as required in the following Articles, all in accordance with the provisions hereof within 15 calendar days or such additional time as may be allowed by the Engineer from the date of the mailing of a notice of award of bid according to the address given by him, of the acceptance of his proposal. If a bidder to whom award is made fails or refuses to enter into Contract as herein provided, or to conform to any of the stipulated requirements in connection therewith, the money represented by Bidder's security check or Bond shall be forfeited to the OWNER, the award will be annulled, and at the discretion of the OWNER the Contract may be awarded to the next lowest bidder; and such bidders shall fulfill every stipulation embraced herein as if he were the party to whom the first award was made. A corporation to which an award is made may be required, before the Contract is finally executed, to furnish evidence of its corporate existence, of its right to do business in California, and of the authority of the officer signing the Contract and bonds for the corporation.

23) Bonds: A bidder to whom the Contract is awarded shall, within the time mentioned in the preceding Article, furnish a bond with a responsible corporate surety or corporate sureties conditioned upon the faithful performance of the said bidder of all covenants and stipulations in the Contract. Said bond is hereinafter referred to as the Faithful Performance Bond. Within the time mentioned in the preceding Article, the bidder to whom the Contract is awarded shall furnish such faithful performance bond, and shall also furnish a Payment Bond within said time frame. The Faithful Performance Bond and the Payment Bond shall be in the form approved by the OWNER and in the amount stipulated in the GENERAL CONDITIONS.

The surety or sureties on all bonds furnished must be satisfactory to the OWNER. The party required to furnish bonds pursuant to these instructions shall furnish such bonds at his/her own cost and expense. The OWNER reserves the right to reject any bond if, in the opinion of the Engineer, the sureties' acknowledgment is not in the form included within the Contract Documents or in another form substantially as prescribed by law.

Sweet Springs GW Monitoring Wells ITB - Page 8 of 10 June 2026

24) Insurance Policies and Bonds: Attention is directed to the provisions of the Insurance Code of the State of California with reference to the writing of insurance policies and bonds covering risks located in this state, and the premiums and commissions thereon. A bidder to whom the Contract is awarded shall furnish, at the time his bond or bonds are submitted for approval, satisfactory evidence that the requirements of said Code have been observed, including proof of unemployment insurance. The required bonds must be provided only by surety insurer who is duly admitted by the Insurance Commissioner of the State of California.

25) Liability Insurance: Before the Contract is executed on behalf of the OWNER, a bidder to whom the Contract has been awarded shall furnish to the OWNER the necessary policy or certificate of liability insurance in which the OWNER and the Engineer shall be named as additional insureds with the bidder in the amount specified in the SUPPLEMENTARY GENERAL CONDITIONS, ARTICLE 11, entitled "Insurance." The policy shall insure the OWNER, the Engineer, the OWNER's officers and employees, the bidder, his employees and his Subcontractors and their employees, and their heirs, agents, and employees, while acting within the scope of their duties, against all claims arising out of or in connection with the work to be performed and shall remain in full force and effect until the work is accepted by the OWNER. The Policy shall provide for the limits stated with any insurance policy carried out by the OWNER.

26) Assignment of Contract: No assignment by the Contractor of any contract to be entered into in accordance with the Notice Inviting Bids and these Instructions to Bidders, or any part thereof, or of funds to be received thereunder, will be recognized by the awarding authority unless such assignment has had prior approval of the awarding authority and the surety has had notice of such assignment in writing and has given his/her written consent thereto.

27) Non-Collusion Affidavit: Section 7106 of the Public Contract Code requires that each bidder execute a Non-collusion Affidavit on all public works contracts. Bidder shall execute the Non-collusion Affidavit included with the Contract Documents and submit it to the OWNER with the Proposal.

28) Disqualification of Bidder: If there is a reason to believe that collusion exists among any of the bidders, none of the bids of the participants in such collusion will be considered, and the OWNER may likewise elect to reject all bids received.

29) Rejection of Proposals: The OWNER reserves the right to reject any proposals which are incomplete, obscure, or irregular, any proposals which omit a bid on any one or more items for which bids are required; any proposals which omit unit prices if unit prices are required; any proposal in which unit prices are unbalanced in the opinion of the OWNER;

any proposals accompanied by insufficient or irregular proposal guaranty; and any proposals from bidders who have previously failed to perform properly or to complete contracts of any nature on time.

30) Relief of Bidders: Attention is directed to the provisions of Public Contract Code Section

5100, et seq., concerning relief of bidders, and in particular to the requirement therein that if a bidder claims a mistake was made in its bid, the bidder shall give the OWNER written notice within five (5) calendar days after the opening of the bids of the alleged mistake, specifying in the notice, in detail, how the mistake occurred.
