QUESTION: After window submittal approval (estimated to be first week of June), it is anticipated that the fabrication would take at a minimum 6 weeks, given the current supply chain conditions.

QUESTION: Who will perform the air clearance testing at the completion of construction, and pay for the services? Will the School District engage a testing firm, or is this the responsibility of the Contractor?

ANSWER: The school has decided to not have a pre-school program in 2023 so no post construction air clearance will be required for this project. A full wipe down using EPA approved cloth is required as described below. The District will pay for all air clearance services post abatement. Testing is not the responsibility of the general contractor.

“Wipe down all surfaces with EPA approved cloth for RRP. EPA protocol requires use of disposable cleaning cloths to wipe the floor and other surfaces of the work area and compare these cloths to an EPA-provided cleaning verification card to determine if the work area was adequately cleaned.”
