All work involving the disturbance of lead containing materials need to meet the requirements of the OSHA Lead in Construction Standard at 29 CFR 1926.62 including proper employee training, exposure monitoring, engineering controls, work practices, work area demarcation and/or isolation, and prompt cleanup of lead bearing debris. In addition, any welding, cutting, or heating of lead painted metal surfaces or pipes would also need to meet applicable requirements of 29 CFR 1926.353(c)(2)(i) and 29 CFR 1926.354(c)(1) if performed in an enclosed space. GSA requires a written lead work Method of Procedure (MOP) describing all of this for review and acceptance prior to the work being performed.

F. The following is a list of some items that the contractor shall follow in the performance of their work:

1. Use workers that are properly trained per the OSHA Lead standard.

2. Use PPE as determined by the OSHA defined competent person.

3. Use lay down poly sheeting in work areas and demarcate work areas with signage.

4. Conduct initial exposure assessment and monitoring as required by the standard.

5. If paint needs to be scrapped off, use wet scraping, HEPA vac at point of scrape, etc.

6. Promptly clean up dust and debris.

7. Workers shall practice good hygiene practices in accordance with the OSHA standard.

8. Manage waste stream appropriately.

3.05 EXECUTION

A. GSA BUILD GREEN STANDARDS - SALVAGED, OR RE-USED BUILDING MATERIAL

1. Items and material located in the existing space, or to be removed from the existing space during the demolition phase, are eligible for reuse in the construction phase of the project. The reuse of items and materials is preferable to recycling them; however, items considered for reuse must be in refurbishable condition, and must meet quality standards as approved by GSA.

B. GSA BUILD GREEN STANDARDS - CONSTRUCTION WASTE MANAGEMENT

1. Recycling construction waste means providing all services necessary to furnish construction materials or wastes to organizations, which will employ these materials, or wastes in the production of new materials. Recycling includes required labor and equipment necessary to separate individual materials from the assemblies of which they form a part.

The Contractor shall submit to the Government their proposal to dispose of or recycle construction waste. Where the small quantity of material, the extraordinarily complex nature of the waste disposal method, or prohibitive expense for recycling would represent a genuine hardship, the Government may permit alternative means of disposal.

The Contractor will recycle the following items during both the demolition and construction phases of the project, subject to economic evaluation and feasibility:

• Ceiling grid and tile,

• Light fixtures, including proper disposal of any transformers, ballasts and fluorescent light bulbs,

• Duct work and HVAC equipment,

• Wiring and electrical equipment,

• Aluminum and/or steel doors and frames,

• Hardware,

• Drywall,

• Steel studs,

• Carpet, carpet backing, and carpet padding,

• Wood,

• Insulation, Project No. 2446 02 4120–4 CUTTING AND PATCHING

• Cardboard packaging,

• Pallets,

• Windows and glazing materials,

• All miscellaneous metals (as in steel support frames for filing equipment), and

• All other finish and construction materials.

If any waste materials encountered during the demolition or construction phase are found to contain lead, asbestos, PCBs (such as fluorescent lamp ballasts), or other harmful substances, they are to be handled and removed in accordance with State and Federal laws and requirements concerning hazardous waste.

In addition to providing “one-time” removal and recycling of large-scale demolition items such as carpeting or drywall, the Contractor will provide continuous facilities for the recycling of incidental construction waste during initial construction.

Construction materials recycling records shall be maintained and accessible to the Contracting Officer. Records shall include materials recycled or landfilled, quantity, date, and identification of hazardous wastes.

3.06 DEBRIS AND WASTE REMOVAL

A. Remove debris, junk, and trash from site.

B. Remove from site all materials not to be reused on site.

C. Leave site in clean condition, ready for subsequent work.

D. Clean up spillage and wind-blown debris from public and private lands.

3.2 PROTECTION:

Protect finished surfaces installed prior to plastering by covering.

Project No. 2446 0092300–3 SECURITY PLASTER REPAIR

Maintain protection in place until completion of Work.

3.4 PREPARATION FOR PLASTERING:
