2.1 Examination of Bid Documents. Each bidder must carefully examine the entire Invitation to Bid, including the plans, specifications, and all other contract documents, and must satisfy itself as to the conditions to be encountered and the requirements of the work before submitting a bid.

SCHD will not issue any addendum less than 72 hours before bid closing unless the addendum also extends the closing date.

2.5 Bid Preparation and Form. Each bidder must submit its bid on the bid form provided in this Invitation to Bid.

2.7 Bid Closing. SCHD will receive bids until Tuesday, September 22, 2026, at 3:00 p.m. Pacific Time (the “Bid Closing”). SCHD will not accept any bid received after the Bid Closing. Bidders bear the risk of any delay in delivery, and SCHD will not consider late bids.

2.11 Bid Irrevocability. Each bid is irrevocable for 30 days after the Bid Closing.

2.12 Cost of Bid Preparation. SCHD is not liable for any cost a bidder incurs in preparing or submitting a bid.

3. Bid Security

3.1 Bid Security Required. Each bid must be accompanied by bid security in an amount equal to ten percent of the total bid, consisting of the base bid together with all additive alternates. Bid security is required because the estimated value of this public improvement contract exceeds $100,000. SCHD may reject as nonresponsive any bid not accompanied by the required bid security.

3.2 Acceptable Forms of Bid Security. A bidder must submit bid security in one of the following forms:

(a) A surety bond from a surety company authorized to do business in Oregon;

(b) An irrevocable letter of credit issued by an insured institution as defined in ORS 706.008; or

(c) A cashier’s check or a certified check.

3.3 Purpose and Forfeiture. Bid security guarantees that the successful bidder will, if awarded the contract, execute the contract and provide all required performance and payment bonds and proof of insurance within the time required. If the successful bidder fails to promptly and properly execute the contract and deliver the required bonds and proof of insurance, the bidder forfeits its bid security. Any forfeited bid security is taken and considered as liquidated damages and not as a penalty.

3.4 Return of Bid Security. SCHD will return the bid security of the successful bidder after the bidder executes the contract and provides all required bonds and proof of insurance. SCHD may return the bid security of unsuccessful bidders after the contract is fully executed or after SCHD rejects all bids. SCHD may return the bid security of unsuccessful bidders before award if doing so does not prejudice the contract award and SCHD retains the security of at least the three lowest bidders pending execution of the contract.

4. Bidder Responsibility and Qualifications

4.1 Responsible Bidder Determination. SCHD will award the contract to the responsible bidder submitting the lowest responsive bid. Before awarding the contract, SCHD will determine whether the apparent low bidder is a responsible bidder under ORS 279C.375. SCHD will not award the contract to a bidder it determines is not responsible.

4.2 Standards of Responsibility. To be found responsible, a bidder must demonstrate to SCHD that the bidder:

(a) Has available, or can obtain, the financial, material, equipment, facility, and personnel resources and expertise necessary to meet all contractual responsibilities;

(b) Holds all current licenses that businesses or service professionals operating in Oregon must hold to perform the work specified in the contract;

(c) Is covered by liability insurance and other insurance in the amounts SCHD requires in these solicitation documents;

(d) Qualifies as a carrier-insured employer or a self-insured employer under ORS 656.407, or has elected workers’ compensation coverage under ORS 656.128;

(e) Has made the first-tier subcontractor disclosure required under ORS 279C.370;

(f) Has completed previous contracts of a similar nature with a satisfactory record of performance;

(g) Has a satisfactory record of integrity;

(h) Is legally qualified to contract with SCHD; and

(i) Has supplied all necessary information in connection with SCHD’s inquiry concerning responsibility.

4.3 Bidder’s Duty to Supply Information. Each bidder must promptly supply any information SCHD requests concerning the bidder’s responsibility. If a bidder fails to promptly supply the requested information, SCHD will determine the bidder’s responsibility based on available information or may find that the bidder is not responsible.

4.4 Contractor Licensing Required. SCHD may not receive or consider a bid for this public improvement contract unless the bidder is licensed by the Oregon Construction Contractors Board as required under ORS chapter 701. The license must be current and valid at the time the bidder submits its bid.

4.5 Ineligible and Disqualified Contractors. SCHD will not award the contract to any bidder that is:

(a) On the list of contractors ineligible to receive public works contracts maintained by the Bureau of Labor and Industries under ORS 279C.860; or

(b) On the list created by the Construction Contractors Board under ORS 701.227 of bidders not qualified to hold a public improvement contract.

4.6 Environmental and Asbestos Licensing. This project involves alteration of an existing building. The District is not aware of any asbestos-containing material in the building, which is a steel structure with a concrete floor and existing tile installed in 1995, and no asbestos survey is required for this project. If any asbestos-containing material is nonetheless discovered, any contractor or subcontractor that performs asbestos abatement work must be licensed as required under ORS 468A.720 and must perform the work in accordance with all applicable requirements.

5. Resident Bidder Disclosure

5.1 Disclosure Required. Each bidder must identify in its bid whether the bidder is a resident bidder as defined in ORS 279A.120, and must complete and submit the Resident Bidder Certification included with this Invitation to Bid.

5.2 Definition. Under ORS 279A.120, a resident bidder is a bidder that has paid unemployment taxes or income taxes in Oregon during the twelve calendar months immediately preceding submission of the bid, has an Oregon business address, and has stated in the bid that the bidder qualifies as a resident bidder. A bidder that does not meet these requirements is a nonresident bidder.

5.3 Reciprocal Preference. In determining the lowest responsible bidder, SCHD will add to the bid of a nonresident bidder a percentage increase equal to the percentage preference, if any, that the nonresident bidder’s home state gives to its own resident bidders. The Oregon Department of Administrative Services publishes annually a list of states that give preference to in-state bidders and the applicable percentages, and SCHD may rely on that list without incurring liability to any bidder. SCHD applies this adjustment only to evaluate bids and it does not change the contract price.

5.4 Effect of Failure to Disclose. SCHD will treat a bidder’s failure to accurately identify its resident or nonresident status in accordance with ORS 279A.120 and SCHD’s rules.

6. First-Tier Subcontractor Disclosure

6.1 Disclosure Required. Because the estimated value of this public improvement contract exceeds $100,000, each bidder must submit a first-tier subcontractor disclosure form. A first-tier subcontractor is a subcontractor that contracts directly with the prime contractor to furnish labor, or labor and materials, on the contract.

6.2 Subcontractors That Must Be Disclosed. A bidder must disclose each first-tier subcontractor furnishing labor, or labor and materials, whose subcontract value is equal to or greater than:

(a) Five percent of the total contract price, but at least $15,000; or

(b) $350,000, regardless of the percentage of the total contract price.

For each disclosed subcontractor, the bidder must provide the subcontractor’s name, the category of work the subcontractor will perform, and the dollar value of the subcontract. If the bidder will not use any subcontractor subject to these requirements, the bidder must indicate “NONE” on the form.

6.3 Deadline for Submission. The bidder must submit the disclosure form to SCHD, at the location specified for bid submission, either with the bid or within two working hours after the Bid Closing, that is, by 5:00 p.m. Pacific Time on Tuesday, September 22, 2026. This deadline is mandatory.

6.4 Failure to Disclose; Responsiveness. Submission of the disclosure form by the deadline is a matter of bid responsiveness. A bid submitted by the Bid Closing for which the required disclosure form is not submitted by the deadline in Section 6.3 is nonresponsive, and SCHD will not consider it for award. SCHD is not required to determine the accuracy or completeness of the information on the form.

6.5 Public Inspection. After bid opening, SCHD will make the disclosure forms available for public inspection and will provide copies to the Bureau of Labor and Industries as required by law.

6.6 Substitution. A bidder or contractor may substitute a disclosed first-tier subcontractor only in accordance with ORS 279C.585. A person may file a complaint regarding improper substitution with the Construction Contractors Board under ORS 279C.590.

7. Prevailing Wage Rate Requirements

7.1 Public Work Subject to State Prevailing Wage. This project is a public work subject to the Oregon Prevailing Wage Rate Law, ORS 279C.800 to 279C.870. Each contractor and subcontractor performing work on the project must pay its workers not less than the applicable prevailing rate of wage for each trade or occupation, as determined by the Commissioner of the Bureau of Labor and Industries, in accordance with ORS 279C.838 and 279C.840.

7.2 Applicable Rates. The prevailing wage rates applicable to this project are those contained in the Bureau of Labor and Industries publication Prevailing Wage Rates for Public Works Contracts in Oregon, dated July 5, 2026, which is incorporated into the specifications and this Invitation to Bid by reference. The applicable rates are those in effect on the date SCHD first advertises this Invitation to Bid, and those rates apply for the duration of the project. The rate publication, including the definitions of covered occupations, is available on the Bureau website at https://www.oregon.gov/boli.

7.3 Bidder’s Compliance Statement. SCHD will not receive or consider any bid for this contract unless the bid contains the bidder’s statement that “Contractor agrees to be bound by and will comply with the provisions of ORS 279C.838 or 279C.840.” SCHD will not consider a bid that does not contain this statement.

7.4 Public Works Bond. Before starting work on the project, the contractor and every subcontractor must have a $30,000 public works bond filed with the Construction Contractors Board, unless exempt under ORS 279C.836. This bond is in addition to any performance or payment bond required under this contract. The public works bond is a continuing obligation and secures payment of unpaid wage claims ordered by the Bureau.

7.5 Fee to the Bureau. SCHD will pay the fee required under ORS 279C.825 to the Bureau for the public works project.

7.6 Certified Payroll and Posting. Each contractor and subcontractor must keep accurate records, file certified statements of the hourly rate of wage paid to each worker as required under ORS 279C.845, and post the applicable prevailing wage rates and any fringe benefit plan information at the worksite as required by law.

7.7 Apprentices. The contractor must pay any apprentice employed on the project in accordance with the registered apprenticeship program under which the apprentice is registered and must employ the apprentice in accordance with applicable apprenticeship requirements.

8. Bid Opening and Evaluation

8.1 Public Bid Opening. SCHD will open and read the bids publicly at the date, time, and place stated in Section 2.9. After opening, all bids and the first-tier subcontractor disclosure forms are public records and are available for public inspection.

8.2 Responsiveness. SCHD will consider only responsive bids for award. A responsive bid is one that substantially complies in all material respects with this Invitation to Bid and all applicable requirements. SCHD may reject any bid that does not comply with the prescribed public contracting procedures and requirements, including the requirement to demonstrate the bidder’s responsibility under ORS 279C.375(3)(b).

8.3 Basis of Award. SCHD will award the contract to the responsible bidder submitting the lowest responsive bid, subject to SCHD’s right to reject bids under Section 8.5. In determining the lowest responsible bidder, SCHD will add to each base bid the additive alternates SCHD selects, in the predetermined order stated in the Bid Form: Additive Alternate No. 1 (exterior painting), then Additive Alternate No. 2 (parking lot resurfacing). SCHD will determine before award how many alternates it will accept based on available funds. SCHD will apply the reciprocal preference in Section 5 and determine responsibility under the standards in Section 4.

8.4 Determination of Responsibility. Before awarding the contract, SCHD will determine that the apparent low bidder is responsible under ORS 279C.375(3)(b). SCHD will check the list maintained by the Construction Contractors Board under ORS 701.227 of bidders not qualified to hold a public improvement contract and will consider whether the bidder meets the responsibility standards in Section 4. If SCHD finds the apparent low bidder is not responsible, SCHD will document the basis for that finding and will file its determination with the Construction Contractors Board within 30 days after award.

8.5 Rejection of Bids. SCHD may reject any bid not in compliance with all prescribed public bidding procedures and requirements. After finding that doing so is in the public interest, SCHD may reject for good cause all bids upon a written finding. SCHD may cancel this solicitation or reject any or all bids in accordance with ORS 279C.395 and OAR 137-049-0270.

8.6 Notice of Intent to Award. At least seven days before awarding the contract, SCHD will issue to each bidder, or post electronically or otherwise, a notice of SCHD’s intent to award the contract, unless SCHD determines under the applicable rules that seven days is impractical. The notice will conform to OAR 137-049-0395.

8.7 Protest of Award. An adversely affected or aggrieved bidder may submit a written protest of SCHD’s intent to award within seven days after issuance of the notice of intent to award. A bidder is adversely affected or aggrieved only if the bidder is eligible for award as the responsible bidder submitting the lowest responsive bid and is next in line for award, that is, the bidder must claim that all lower bidders are ineligible for award. The protest must be in writing and must specify the grounds on which it is based. SCHD will not consider a protest submitted after this deadline.

8.8 Correction or Withdrawal of Bids. SCHD will handle correction or withdrawal of a bid because of an inadvertent, nonjudgmental mistake, before or after bid opening, in accordance with OAR 137-049-0350.

9. Award, Execution, and Bonds

9.1 Award. Based on competitive bids, SCHD may award the public improvement contract to the responsible bidder submitting the lowest responsive bid. The SCHD Board of Directors, acting as the Local Contract Review Board, will authorize the award.

9.2 Execution of Contract. The successful bidder must execute the contract and deliver all required bonds and proof of insurance within 10 days after SCHD issues the contract for signature, or within the time stated in the notice of award. Time is of the essence.

9.3 Performance Bond and Payment Bond. Because this public improvement contract exceeds $100,000, the successful bidder must furnish a performance bond and a separate payment bond, each in an amount equal to the full contract price, as required under ORS 279C.380. The bonds must be executed by a surety company authorized to do business in Oregon on forms acceptable to SCHD.

9.4 Insurance. The successful bidder must provide proof of insurance in the types and amounts required by the contract documents before SCHD executes the contract.

9.5 Public Works Bond. Before starting work, the contractor and every subcontractor must have on file with the Construction Contractors Board the $30,000 public works bond required under Section 7.4, unless exempt.

9.6 Failure to Execute. If the successful bidder fails to execute the contract and deliver the required bonds and proof of insurance within the time required, the bidder forfeits its bid security as liquidated damages, and SCHD may award the contract to the next lowest responsible bidder or may reject all bids.

10. Contract Terms and Required Statutory Conditions The construction contract will include the conditions required for public improvement contracts under ORS 279C.505 to 279C.530, including provisions concerning payment of claims, liens, hours of labor, environmental and natural resources compliance, and workers’ compensation. A sample contract is included with the bid documents.
