951-1 Control of Quality.
All timber products manufactured for incorporation into the work shall be produced by a producer/treater approved by the Department for such production. Obtain timber products from a plant that is currently on the Department’s Production Facility Listing. Producers seeking inclusion on the list shall meet the requirements of Section 105. If approval is withdrawn by the Department during product ion for a construction project, it is the Contractor’s responsibility to obtain another approved producer/treater to produce the timber products, or await reestablishment of approval of the disapproved producer/treater. Cost or delays associated with producer/treater approval or disapproval shall be borne by the Contractor. The producer/treater of timber products shall exercise quality control through an approved Producer Quality Control (QC) Plan conforming to Section 105. Products produced under this QC Plan will not relieve the Contractor of his responsibility for unsuitable materials or workmanship, which might become apparent at the job site, nor of the necessity of his replacing any material which might be determined upon subsequent inspection to be u nsuitable.
951-2 Preparations Prior to Requesting Inspection.
Prior to the requested time of inspection for approval of a producer/treater, the authorities of the treating plant shall become knowledgeable with the most current requirements of the Departme nt’s Specifications as appropriate to his production/treatment. The producer/treater shall make his facility totally accessible to appropriate Department's inspection personnel. Such access for inspection shall include, but not be limited to, all physical artifacts and processes, materials records and copies of certified shipping documents (such as a treatment certification, a treating report, and an assay report). All calls for inspections shall be made at least two weeks in advance. Upon approval of a pr oducer/treater facility, the Department will inspect the facility periodically for continued approval.
951-3 Certification.
Each order/shipment to the job site must be accompanied with a notarized certification indicating compliance to the appropriate spe cifications. The certification shall include: the project/order number, charge numbers, and assay retention results. The producer/treater shall maintain all pertinent documents for a period of three years. Each timber product must also have a preapproved p roducer/treater identification mark on every item delivered to the job site. FY 2023-24 Return to Table of Contents
