11/27/2023 Rev 7/8/2026

INSTRUCTIONS TO BIDDERS

(Construction Form RA-1a)

The Invitation For Bids (“IFB”) consists of these Instructions To Bidders, the Bid Form, the General Conditions of the Construction Contract, the Supplemental General Conditions (if any), the Special Conditions (if any), the Forms to be used, and the Scope of Work as described by the Plans and Specifications, other documents listed in the Specifications, and any addenda which may be issued, all of which request qualified bidders to submit competitive prices or bids for providing the described work of the Contract.

As used herein, the terms “bidder” and “Contractor” both shall refer to the Person submitting a bid.

1. CONDITIONS AT SITE OR STRUCTURE: Bidders shall visit the Site and shall be responsible for ascertaining pertinent local conditions such as location, accessibility, general character of the Site, structure or building, and the character and extent of existing conditions, improvements or work within or adjacent to the Site. No Claims shall be submitted as a result of Bidder’s failure to have done so, but shall be deemed waived and will not be considered by the Owner. See Section 7 of the General Conditions entitled "Conditions at Site."

2. EXPLANATIONS TO BIDDERS: No oral explanation in regard to the meaning of drawings and specifications will be made and no oral instructions will be given before the award of the Contract. The Owner shall not be responsible for any conclusions, assumptions or interpretations made by bidders during the preparation of bids that are contrary to the Drawings and Specifications and their clear intent. Discrepancies, conflicts, errors, omissions or doubts as to the meaning of the Contract Documents shall be communicated in writing to the A/E for interpretation. Bidders must so act to assure that questions reach the A/E at least six (6) calendar days prior to the time set for the receipt of bids to allow a sufficient time for an addendum to reach all bidders before the submission of their bids. If, however, there are two (2) weeks or less between the first bid advertisement and the time set for receipt of bids, then bidders must submit questions so that they reach the A/E no later than three (3) business days prior to the time set for receipt of bids. Any interpretation made will be in the form of an addendum which will be forwarded to all bidders, and its receipt shall be acknowledged by the bidder on Bid Forms. If such discrepancies, conflicts, errors, omissions or doubts are reasonably apparent or should have been reasonably apparent to the bidder, and the bidder failed to submit questions to the A/E in the time and manner required herein and the Contract is awarded to the bidder, then any claims shall be deemed waived and the bidder shall not be entitled to additional compensation or time, or entitled to sue the Owner based on such discrepancies, conflicts, errors, omissions, or doubts.

3. TIME FOR COMPLETION:

(a) "Time for Completion" shall be designated by the Owner on the Invitation for Bids or other prebid documents and shall mean the number of consecutive calendar days

11/27/2023 Rev 7/8/2026 following the issuance of the Notice to Proceed which the Contractor has to substantially complete all Work required by the Contract. In some instances, the Time for Completion may be stated in the form of a Contract Completion Date based on a stipulated date of Notice to Proceed.

Unless otherwise specified, the Contractor shall achieve Final Completion within thirty (30) calendar days after the date of Substantial Completion.

(b) When the Notice to Proceed is issued, it will state a Contract Completion Date, which has been set by the Owner based on date of the Notice to Proceed and the Time for Completion.

(c) The Contractor, in preparing and submitting its bid, is required to take into consideration adverse weather conditions specified in General Conditions Section 6.

4. PREPARATION AND SUBMISSION OF BIDS:

(a) Bids shall be submitted on the forms furnished, or copies thereof, and shall be signed in ink. Erasures or other changes in a bid must be explained or noted over the signature of the bidder. Bids containing any conditions, omissions, unexplained erasures, alterations or items not called for in the proposal, or irregularities of any kind, may be rejected by the Owner, in its sole discretion, as being incomplete or nonresponsive.

(b) Each bid must give the complete legal name and full business address of the bidder and be signed by the bidder, or the bidder's authorized representative. Bids by partnerships must be signed in the partnership name by one of the general partners of the partnership or an authorized representative, followed by the designation/title of the person signing, and a list of the partners. Bids by joint ventures must be signed in the joint venture name by one of the joint venturers or an authorized representative of one of the joint venturers, followed by the designation/title of the person signing, and a list of the joint venturers. Bids by corporations must be signed with the legal name of the corporation followed by the name of the state in which it is incorporated and by the signature and title of the person authorized to bind it in this matter. The name of each person signing shall be typed or printed below the signature. A signature on a bid by a person who identifies their title as "President," "Secretary," "Agent" or other designation without disclosing the principal firm, shall be held to be the bid of the individual signing. When requested by the Owner, satisfactory evidence of the authority of the officer signing on behalf of the corporation shall be furnished. Trade or fictitious names may be referenced by using "t/a _ _ _ ," but bids shall be in the legal name of the person or entity submitting the bid.

(c) Bids with the bid guarantee shall be enclosed in a sealed envelope which shall be

11/27/2023 Rev 7/8/2026 marked and addressed as indicated by the advertisement. NOTE: For bidders submitting electronic bids via eVA’s electronic bidding system, security for bid bonds must be submitted to the on premises address noted within the specific IFB by the bid due date. If a Contract is for one hundred fifty thousand dollars ($150,000) or more, or if the total value of all construction, removal, repair or improvements undertaken by the bidder within any twelve-month period is one million dollars ($1,000,000) or more, the bidder is required under Code of Virginia §§ 54.1-1100, et seq., to be licensed in Virginia as a "Class A Contractor." If a Contract is for thirty thousand dollars ($30,000) or more, but less than one hundred fifty thousand dollars ($150,000), or if the total value of all construction, removal, repair or improvements undertaken by the bidder within any twelve-month period is two hundred fifty thousand dollars ($250,000) or more, but less than one million dollars ($1,000,000), the bidder is required to be licensed in Virginia as a "Class B Contractor." The bidder shall place on the outside of the envelope containing the bid and shall place in the bid over its signature whichever of the following notations is appropriate and insert its Contractor license/registration number:

Licensed Class A Virginia Contractor No.

or Licensed Class B Virginia Contractor No.

If the bidder is not properly licensed in Virginia at the time the bid is submitted, or if the bidder fails to provide this information on its bid or on the envelope containing the bid and fails to promptly provide said Contractor license number to the Owner in writing when requested to do so before the opening of bids, the bidder shall be deemed to be in violation of Code of Virginia § 54.1-1115 and its bid will not be considered.

(d) The bidder must place its Employer Identification Number (SSN or FEIN) in the space provided on the Bid Form.

(e) Every bidder organized as a stock or nonstock corporation, limited liability company, business trust, or limited partnership or registered as a registered limited liability partnership must be authorized to transact business in the Commonwealth as a domestic or foreign business entity if so required by Title 13.1 or Title 50 of the Code of Virginia, as amended, or as otherwise required by law. Any bidder organized or authorized to transact business in the Commonwealth pursuant to Title

13.1 or Title 50 must include in its bid the identification number issued to it by the State Corporation Commission. Any bidder that is not required to be authorized to transact business in the Commonwealth as a foreign business entity under Title 13.1 or Title 50 or as otherwise required by law shall include in its bid or proposal a statement describing why the bidder is not required to be so authorized. A bidder required to be authorized to transact business in Virginia that fails to provide the required information shall not receive an award unless a waiver of this requirement and of any administrative policies and procedures established to implement Code of Virginia § 2.2-4311.2 is granted by the chief executive of the Owner.

11/27/2023 Rev 7/8/2026

If awarded the Contract, the bidder shall not allow its existence to lapse or its certificate of authority or registration to transact business in the Commonwealth, if so required under Title 13.1 or Title 50, to be revoked or cancelled at any time during the term of the Contract. Doing so shall be deemed to be a violation of Code of Virginia § 2.2-4311.2 and the bidder understands and agrees that the Owner may void the Contract if the bidder fails to comply with this provision.

(f) Code of Virginia, § 2.2-4376.2 shall be applicable to the Work of the Contract.

5. BID GUARANTEE:

(a) Any bid (including the Total Base Bid plus all Additive Bid Items) which exceeds five hundred thousand dollars ($500,000) shall be accompanied by a Standard Bid Bond, Form RA-1d, payable to the Owner as obligee in an amount equal to five percent (5%) of the amount of the bid (the “Bid Bond”).

NOTE: For bidders submitting electronic bids via eVA’s electronic bidding system, security for bid bonds must be submitted to the on-premises address noted within the specific IFB if they do not qualify for the following: The Owner agrees to accept a Bid Bond on which the Surety has utilized electronic signatures and/or electronic notarization if the electronic notarization meets the requirements of Virginia Code §§ 47.1-6.1, -7, and -12, and the Commonwealth of Virginia State Corporation Commission Bureau of Insurance and the Bid Bond contains any SURETY BOND SEAL ADDENDUM established by the Commonwealth of Virginia State Corporation Commission Bureau of Insurance.

The Bid Bond must be issued by a surety company which is legally authorized by the Virginia State Corporation Commission to do surety business in the Commonwealth of Virginia. Such Bid Bond shall guarantee the following: that the bidder will not withdraw its bid during the sixty (60) day period following the date of the opening of bids; that if the bid is accepted, the bidder will enter into the Contract with the Owner described in the IFB; that the bidder can and will submit a properly executed and authorized Standard Performance Bond and Standard Labor and Material Payment Bond on the forms included in the IFB. If the bidder withdraws its bid within the sixty (60) day period following bid opening, fails to enter into the Contract, or fails to provide the required Standard Performance Bond and Standard Labor and Material Payment Bond within ten (10) days after the bidder’s receipt of notice of acceptance of its bid, the bidder and the bidder’s surety shall be jointly and severally be liable to the Owner for the difference between the amount specified in the bidder’s bid and such larger amount for which the Owner may contract with another party to perform the work covered by said bid, up to the amount of the bid guarantee of 5% of the bidder’s total bid amount, as the damage to the Owner resulting from the bidder’s default. See Code of Virginia §2.2-4336.

(b) Code of Virginia § 2.2-4338 contains provisions allowing for alternative forms of bid security in lieu of a Bid Bond. A bidder’s use of an alternative form of Security as listed

11/27/2023 Rev 7/8/2026 in Code of Virginia § 2.2-4338.B must be approved by the Owner prior to the bidder’s submission of its bid on the Bid Receipt date and time to be accepted in lieu of a Bid Bond.

(c) The Bid Bond or other alternative bid security will be returned to all but the three lowest bidders after the formal opening of bids. The remaining Bid Bonds or bid security will be returned to the bidders after the Owner and the accepted bidder have executed the Contract and the required Standard Performance Bond and the Standard Labor and Material Payment Bond for the Contract have been received and approved by the Owner.

(d) If the Contract and required bonds have not been executed by the accepted bidder within sixty (60) days after the date of the opening of the bids, then the Bid Bond or other bid security of any bidder will be returned upon a bidder’s request, provided the bidder has not been notified of the acceptance of its bid prior to the date of such request.

6. WITHDRAWAL OR MODIFICATION OF BIDS: Bids may be withdrawn or modified by written or telefaxed notice received at the designated location from bidders prior to the deadline fixed for bid receipt, or the bidder shall give notice in writing of his claim of right to withdraw his bid within two business days after the conclusion of the bid opening procedure and shall submit original work papers with such notice. E-mail withdrawals and modifications are not acceptable. The withdrawal or modification may be made by the person who signed the bid or by an individual(s) who is authorized by the bidder on the face of the bid. Written modifications may be made on the bid form itself, on the envelope in which the bid is enclosed, or on a separate document. Written modifications, whether the original is delivered or telefaxed, must be signed by the person making the modification or withdrawal. The modification must state specifically what is to be modified and by what amount or it must state the item to be modified and what the corrected amount should be.

7. RECEIPT OF BIDS:

(a) Bids will be received at or before the date and time stated within the bid documents by one of two different methods:

Mail/Hand Delivery: On premises at the address noted within this notice at the time (local) and date noted within this notice.

or

Electronic: Invitation for Bids will be posted to the eVA site where potential vendors may submit electronically their bids to the Authority through the eVA site*.

*-Prospective bidders who use the eVA site must register through that site. This https://eva.virginia.gov/index.html

11/27/2023 Rev 7/8/2026 site is managed by the Commonwealth of Virginia, Department of Purchase and Supply (New Supplier Registration Guide). Rivanna Water & Sewer Authority does not maintain this site or have any input or control over the registration process. Once the bid due date and time has been reached, the Authority will first read the bids that were properly received on premises. Second, the Authority will then open the electronic bids and read them aloud.

(b) It is the responsibility of the bidder to assure that its bid and any bid modifications are delivered to the place designated for receipt of bids by the date and hour (deadline) set for receipt of bids. Therefore, it is the bidder’s responsibility to take into account all factors which may impact on its bid deliverer / courier’s ability to deliver the bid and to implement whatever actions are necessary to have the bid delivered to the proper bid receipt location prior to the bid receipt deadline. No bids or bid modifications submitted or offered after the date and hour designated for receipt of bids will be accepted or considered.

(c) The Bid Officer is the Owner's representative designated to receive bids at the time and place noted in the IFB and to open the bids received at the appointed time.

(d) The official time used for the receipt of responses is determined by reference to the clock designated by the Bid Officer. The Bid Officer shall determine when the Bid Receipt Deadline has arrived and shall announce that the Deadline has arrived and that no further bids or bid modifications will be accepted. All bids and bid modifications in the possession of the Bid Officer and their assistants at the time the announcement is completed are deemed to be timely, whether or not the bid envelope has been physically date/time stamped or otherwise marked by the time the Bid Officer makes the deadline announcement.

(e) In the event the bid receipt occurs during a period of suspended Rivanna business operations, the receipt and opening will be delayed one business day.

8. OPENING OF BIDS:

(a) Bids will be opened at the time and place stated in the IFB or as modified by subsequent Addenda, and their contents publicly announced. The Bid Officer shall decide when the specified time for bid opening has arrived. No responsibility will be attached to any officer or agent for the premature opening of a bid not properly addressed and identified.

(b) The provisions of Code of Virginia § 2.2-4342, as amended, shall be applicable to the inspections of bids received.

(c) In the event the bid opening date occurs during a period of suspended Rivanna business operations, the opening will be delayed until the next business day at the same time.

11/27/2023 Rev 7/8/2026

9. ERRORS IN BIDS: A bidder may withdraw its bid from consideration if the price bid was substantially lower than the other bids due solely to a mistake therein, provided the bid was submitted in good faith, and the mistake was a clerical mistake as opposed to a judgment mistake, and was actually due to an unintentional arithmetic error or an unintentional omission of a quantity of work, labor or material made directly in the compilation of a bid, which unintentional arithmetic error or unintentional omission can be clearly shown by objective evidence drawn from inspection of original work papers, documents and materials used in the preparation of the bid sought to be withdrawn.

In accordance with Code of Virginia § 2.2-4330(B)(2), to withdraw its bid the bidder must submit to the Owner its original work papers, documents and materials used in the preparation of the bid within two (2) business days after the opening of bids. Such work papers must be submitted in an envelope or package separate and apart from the envelope containing the bid and marked clearly as to the contents and shall be delivered to the Owner by the bidder in person or by registered mail. The bids shall be opened at the time designated in the IFB, as amended by addendum. Once the bids have been opened, the bidder shall have two (2) business days after the opening of bids within which to claim in writing any mistake as defined herein and withdraw its bid. The Contract shall not be awarded by the Owner until such two-day period has elapsed. Such mistake shall be proved only from the original work papers, documents and materials delivered to the Owner. This procedure in Code of Virginia § 2.2-4330(B)(2) shall not apply to when the entire bid is required to be submitted on a unit price basis.

Failure of a bidder to submit its original work papers, documents and materials used in the preparation of its bid shall constitute a waiver by that bidder of its right to withdraw its bid due to a mistake. No bid may be withdrawn under this section when the result would be the awarding of the Contract on another bid of the same bidder or of another bidder in which the ownership of the withdrawing bidder is more than five (5%) percent.

No bidder who is permitted to withdraw a bid shall, for compensation, supply any material or labor to or perform any subcontract or other work agreement for the person or firm to whom the Contract is awarded or otherwise benefit, directly or indirectly, from the performance of the project for which the withdrawn bid was submitted. The person or firm to whom the Contract was awarded and the withdrawing bidder are jointly liable to the Owner in an amount equal to any compensation paid to or for the benefit of the withdrawing bidder without such approval.

If the apparent low bid is withdrawn under authority of this section, the lowest remaining bid shall be deemed to be the low bid on the project.

10. REJECTION OF BIDS: The Owner reserves the right to cancel the IFB, to reject any and all bids at its sole discretion when such rejection is in the interest of the Owner, or to reject the bid of any bidder who is determined to be not responsive or not responsible. See Code of Virginia § 2.2-4319.

11/27/2023 Rev 7/8/2026

11. DETERMINATION OF RESPONSIBILITY

Each bidder shall be prepared, if so requested by the Owner, to present evidence of its experience, qualifications and financial ability to carry out the terms of the Contract.

Prior to award of the Contract, an evaluation will be made to determine if the low bidder has the capability, in all respects, to perform fully the contract requirements and the moral and business integrity and reliability which will assure good faith performance, and who has been prequalified, if required. Factors to be evaluated include, but are not limited to:

(a) sufficient financial ability to perform the contract as evidenced by the bidder's ability to obtain payment and performance bonds from an acceptable surety;

(b) appropriate experience to perform the Work described in the bid documents;

(c) any judgments entered against the bidder, or any officers, directors, partners or owners for breach of a contract for construction;

(d) any substantial noncompliance with the terms and conditions of prior construction contracts with a public body without good cause where the substantial noncompliance is documented; or

(e) a conviction of the bidder or any officer, director, partner, project manager, procurement manager, chief financial officer, or owner in the last five years of a crime relating to governmental or nongovernmental construction or contracting;

and/or

(f) any current debarment of the contractor, any officer, director or owner, from bidding or contracting by any public body of any state, any state agency, or any agency of the federal government.

The Owner reserves the right to disqualify or refuse to accept the bid of any bidder who has been convicted, or entered a plea of guilty or nolo contendere, in any federal or state court to any charge involving any unlawful, corrupt or collusive practice involving a public contract whether federal, state, or local, or who has been determined in any judicial proceeding to have violated any antitrust, bid-rigging or collusive practice statute in connection with any public contract, or against whom such formal criminal prosecution or other judicial proceeding has been initiated.

A bidder who, despite being the apparent low bidder, is determined not to be a responsible bidder shall be notified in writing in conformance with the procedures in Code of Virginia § 2.2-4359.

12. AWARD OF CONTRACT

(a) Basis for Contract Award: The Contract, if awarded, will be awarded to the lowest responsive and responsible bidder, if any, provided its bid is reasonable and it is in the best interest of the Owner to accept it and subject to the Owner's right to reject any and all bids and to waive informality in the bids and in the bidding. The Bid Form may contain a multi-part Base Bid and may contain Additive Bid Items.

11/27/2023 Rev 7/8/2026

Determination of the lowest responsible bidder, if any, will be based on the Total Base Bid Amount entered on the Bid Form including any properly submitted bid modifications plus as many Additive Bid Items taken in sequence as the Owner in its discretion chooses to Award in the best interest of the Owner. Where the sum of the values entered in the multiple parts do not agree with the Total Base Bid amount, the written Total Base Bid Amount entered on the bid form including any properly submitted bid modifications shall take precedence over the numerical Total Base Bid Amount.

In the event that the Total Base Bid from the lowest responsible bidder exceeds available funds, the Owner may negotiate the Total Base Bid amount with the apparent low bidder to obtain a Contract Price within available funds, pursuant to Code § 2.2-4318 and Section 12(c) herein.

(b) Informalities: The Owner reserves the right to waive any informality in the bids when such waiver is in the interest of the Owner.

(c) Negotiation With Lowest Responsible Bidder: If award of the Contract to the lowest responsive and responsible bidder is precluded because of limitations on available funds, under the provisions of Code § 2.2-4318 the Owner reserves the right to negotiate the Total Base Bid amount with the lowest responsive, responsible bidder to obtain a Contract Price within the available funds. This may involve changes in either the features or scope of the work included in the Base Bid. Such negotiations with the apparent low bidder may include reducing the quantity, quality, or other cost saving mechanisms involving items in the Total Base Bid.

Negotiations for Additive Bid Items are excluded. The Owner shall notify the lowest responsive and responsible bidder that such a situation exists and the Owner and bidder shall then conduct their negotiations in person, by mail, by telephone or by any means they find convenient. If an acceptable Contract can be negotiated, any changes to the IFB documents agreed upon in the negotiations shall be summarized in a "Post Bid Modification" and included in the Contract. If an acceptable Contract cannot be negotiated, the Owner shall terminate negotiations and reject all bids.

(d) Notice of Intent to Award or Notice of Award: The “Notice of Intent to Award” or the “Notice of Award” will be posted at the Owner’s standard location for posting notices such as the Owner’s Website. Any bidder who desires to protest the award or decision to award a contract shall submit the protest in writing to the public body no later than ten days after the posting of the Notice of Award or Notice of Intent to Award, whichever comes first. See Code of Virginia § 2.2-4360.

13. CONTRACT SECURITY: For contracts which exceed five hundred thousand dollars ($500,000), the Standard Performance Bond (RA-2a) and the Standard Labor and Material Payment Bond (RA-2b) shall be required, as specified in the IFB.

Enduro “H” Structural Baffl e & Partition Wall

As a global leader for FRP structural systems, En-duro developed the “H” Series baffl e panel and the innovative SlideGuide assembly system.

The 1⁄4” thick, Enduro “H” series are the strongest FRP baffl e panels available and are utilized in both bolted and non-bolted installations. In the Slide- Guide system, the “H” baffl e panels, which do not require fastening, are inserted between and held in place by FRP angles. With a long and proven track record of outstanding performance, the Enduro “H” series and SlideGuide assembly has led a move-ment away from concrete and wood to the Enduro FRP baffl e system.

FRP Technical Data

Corrosion Resistance - Resin Systems Typical Properties of Structural FRP Two standard composite resin systems are available. For most applica-tions, isophthalic polyester fire-retardant (FR-P) is the more widely used. A vinyl ester composite fire-retardant resin system (FR-VE) is recommended where strong acids (such as hydrochloric acid), strong alkalies (such as caustic soda), organic solvents and halogenated organic conditions exist.

An abbreviated Guide is provided below to assist in the selection of the proper resin system for individual application.
