][ 1.6.3 SSPC QP 1 Certification

NOTE: For projects in continental U.S., Hawaii, Alaska, and Puerto Rico, require SSPC Certification. Use in other locations where qualified U.S. Contractor is desired. If project

SECTION 09 90 00 Page 20 involves removal of paint containing hazardous materials, add requirement for SSPC QP 2 certification in section of specification where the hazardous paint removal is specified, generally Section 02 83 00 LEAD REMEDIATION.

NOTE: **WARNING**WARNING**WARNING**WARNING**

Solicitations requiring SSPC Certification must point out the existence and location of the certification requirement, in the Project Information Form. To be enforceable, include the requirement in the solicitation documents. SSPC Certification is a special responsibility requirement pursuant to FAR 9.104-2 Special Standards. This is analogous to requiring bidders to have a specified level of experience or expertise and GAO has sustained these types of special requirements.

NOTE: Use bracket option below concerning SSPC QP 1 only when industrial coatings are required.

Painting qualifications for projects such as BEQ's, training facilities and general administration buildings do not require QP 1 certification.

Contractors that perform surface preparation or coating application on steel substrates must be certified by the Society for Protective Coatings (formerly Steel Structures Painting Council) (SSPC) to the requirements of SSPC QP 1 prior to Contract award, and must remain certified while accomplishing any surface preparation or coating application. If a Contractor's certification expires, the firm will not be allowed to perform any work until the certification is reissued. Requests for extension of time for any delay to the completion of the project due to an inactive certification will not be considered. Notify the Contracting Officer of any change in Contractor certification status. Notify the Contracting Officer of all scheduled and unannounced on-site audits from SSPC and furnish a copy of all audit reports.
