All removal shall be to the extent necessary to properly complete the work of the project. All asbestos and mold related work shall be conducted within regulated areas under negative pressure with a minimum of a two-stage decontamination unit. All lead related work shall be conducted within a negative pressure enclosure for dust control purposes. The Contractor s hazardous materials scope of work includes but is not limited to the following: 1. Areas 3, 4 & 10 For Bidding Purposes, Contractor shall assume that mold is present behind all plaster surfaces scheduled for removal and that mold remediation is required by manual or mechanical scrubbing, sanding or abrasive means at all exposed concrete surfaces and furring scheduled for demolition. Refer to the Destructive Testing Request Form for locations and details. 2. Area 6 & 9 Remove, clean-up and dispose of specified section of wall plaster and asbestos-containing acoustical ceiling plaster. All cuts shall have a clean edge and be encapsulated with a bridging encapsulant upon completion of inspection by the District s Environmental Consultant.
