The San Francisco Unified School District (SFUSD) is soliciting proposals for conducting asbestos related work to support Destructive Testing at Marina Middle School: B. The hazardous materials abatement portion of the project includes removal, clean-up, decontamination, and proper disposal of asbestos and lead containing materials as necessary to support the Destructive Testing Project. Asbestos and lead related work will take place in areas of work indicated Destructive Testing Request Form and associated floor plans HAZARDOUS COMMUNICATION A. Hazardous materials present in the building(s) and structures at this site include: asbestos containing materials (ACMs); assumed asbestos containing materials; asbestos containing construction materials (ACCMs); lead-based paint (LBP); lead-containing coatings and materials; and mercury containing fluorescent lighting tubes, switches, and thermostats SCOPE OF WORK A. The Contractor(s) work includes the removal of asbestos-containing materials, finishes coated with lead-based paint (LBP) and/or lead-containing paints (LCP) to the extent specified to support the Destructive Testing Project. The Contractor is responsible for coordination with the General Contractor for the completion of the work of the project. All removal shall be to the extent necessary to properly complete the work of the project. All asbestos and lead related work must be conducted within regulated area under negative pressure with a minimum of a two-stage decontamination unit. The Contractor s hazardous materials scope of work includes but is not limited to the following: 1. Areas 3 and 16 Remove, clean-up and dispose of specified sections of asbestoscontaining acoustical ceiling plaster and wall plaster with lead-containing paints. All cuts shall have a clean edge and be encapsulated with a bridging encapsulant upon completion of inspection by the District s Environmental Consultant. If mechanical methods are used, all powered equipment must be equipped with a shroud and attached to a functioning HEPA vacuum during operation. Work includes characterizing the plaster with LCP waste stream for lead (TTLC, STLC and TCLP). Refer to the Destructive Testing Request Form for locations and details. 2. Areas 9, 12, 13, 15 and 17 Remove, clean-up and dispose of specified sections of wall and/or ceiling plaster with lead-based paint. Work includes characterizing the waste stream for lead (TTLC, STLC and TCLP). Waste shall be stored in steel drums at the site in a lockable dumpster or designated storage area until all waste characterization results are received and the waste is properly categorized. Refer to the Destructive Testing Request Form for locations and details. 3. Areas 2, 4, 5, 6 Remove, clean-up and dispose of specified sections of plaster with leadcontaining paint coatings. Work includes characterizing the waste stream for lead (TTLC, STLC and TCLP). Waste shall be stored in steel drums at the site in a lockable dumpster or designated storage area until all waste characterization results are received and the waste is October 17, Summary of Hazardous Materials Work

2 properly categorized. Refer to the Destructive Testing Request Form for locations and details. 4. Areas 1, 7, 8, 10, 11, 14) There are no known hazards at these proposed destructive testing locations.

For bidding purposes, Contractor shall assume that 10 linear feet of asbestos-containing pipe insulation will be exposed and require removal over the course of all destructive testing locations WORK SCHEDULE A. The following is the anticipated work schedule as defined by the Destructive Testing Project: 1. Four (4) eight-hour shifts. All hazmat related work must be performed between 6:00pm on a Friday and be fully completed, including clearance sampling and containment removal, by the following Monday at 6;00 am. No Hazmat related work can be performed when students and staff are present. Contractor shall also comply with local noise ordinance requirements RELATED DOCUMENTS A.
