Make the project records usable to the next team
Ask for a material schedule that can be matched to the work areas, a clear statement of retained materials and the specified closeout documentation. The owner, construction manager and following trades need to understand what was removed and what remains. Avoid treating a general completion statement as a replacement for the particular inspection, testing or disposal records the project requires.
Survey and project requirements in Washington
Puget Sound Clean Air Agency publishes separate guidance for renovation and demolition. Have the assessor and contractor confirm the survey scope, applicable notifications and disposal arrangements for the actual property and work. A building permit does not replace the asbestos assessment.
