Bid & Contract Requirements

Construction worker performing building repair

KCHA is required to solicit three or more quotes for all goods and services of more than $10,000. We can only consider your company's bid or proposal if you are licensed and meet insurance requirements. Construction firms must also be bonded. In addition, your company must not appear on any state or federal debarment lists. Requirements for weatherization projects may vary.

General Requirements

As a bidder or contractor, you must:

  • Have a license to do business in Washington State.
  • Have at least 3 years in business under the same name or ownership group.
  • Have industrial insurance coverage for the bidder's employees working Washington.
  • Have an employment security department number.
  • Have a state excise tax registration number.
  • Not appear on any state or federal debarment lists.
  • Be current with payments to the IRS and the state's Labor & Industries, Revenue, and Employment Security departments.
  • Maintain minimum insurance. In most cases this means $1 million per occurrence and $2 million aggregate for general liability. KCHA also normally requires $1 million per accident (combined single limit) for both auto liability and worker's compensation. We may require higher limits or more coverage, depending on the type of work you will do. You must name KCHA as an additional primary/non-contributory insured. All coverage applies equally to subcontractors.

Construction & Maintenance Requirements

In addition to the requirements listed above, construction and maintenance firms must also:

  • Obtain bid bonds for projects of more than $100,000.
  • Obtain payment/performance bonds for 100 percent of the job value for projects of more than $100,000.
  • Agree to retainage of 5 or 10 percent.
  • Have an experience modification factor of 1.0 or less. (May be waived on a case-by-case basis.)
  • Pay Davis-Bacon wages and submit certified payrolls for projects of more than $2,000.
  • Pay Washington state prevailing wages for non-federally funded projects of more than $2,500 at KCHA-owned properties. You must also file intents and affidavits with the Department of Labor & Industries when working on these contracts. Learn more about the prevailing wage law and specific wage rates.

Fair Housing Laws

All contractors that work with KCHA must follow federal fair housing and accessibility laws.

Business Policies

The following policies apply to companies that contract with KCHA:

  • You must work to receive payment. KCHA does not pay in advance.
  • KCHA processes payments within 30 days of invoice receipt if you meet all KCHA compliance requirements.
  • You may invoice materials delivered on site before installation.
  • You must submit certified payrolls every week on federally funded projects, even if no work is done.
  • KCHA may interview up to 10 percent of project workers to verify their employer's wage rates.
  • You must include taxes on materials in bids for prevailing wage projects.
  • Before work starts, both you and KCHA must sign contracts, and KCHA must issue the notice to proceed.
  • KCHA uses AIA contracts for many large construction projects.
  • KCHA uses requests for proposals (RFPs) and qualifications (RFQs) for some construction bids. We use these requests for all professional services contracts.
