Site work for a water / sewer project in North Attleboro, Massachusetts. Completed plans call for site work for a water / sewer project.

The work consists of demolition and replacement of the existing mechanical bar screen's components, grit classifier system, stop plates, grating, and associated piping. Work also consists of electrical upgrades to support the new and rehabilitated process equipment. Contractor Qualification DCAMM Certificate A. If there are additional painted building materials not identified in this section, to be impacted by the Contractor as part of renovation activities notify the Engineer immediately. Contractor is responsible for confirming actual quantities to form the basis of their bid. B. Assumed PCB-contaminated building materials work shall include but not be limited to the materials identified in the Assumed PCB-Containing Building Materials Schedule appended to this Section. 1. It is the sole responsibility of the Contractor to visit the site, review the Contract Documents and determine the quantities of materials to be removed when developing their Bid. C. As further detailed in this Section, no sampling and/or analysis by the Contractor or affiliates of the Contractor (subcontractors, subconsultants, etc.) for total PCBs (Soxhlet Extraction) shall be performed at any point during the performance of the work, except as specifically authorized in writing by the Owner and the Engineer. 1. The Contractor shall collect representative samples of the waste stream for PCB analysis via the Toxicity Characteristic Leaching Procedure (TCLP) for waste disposal purposes only. 2. The Contractor is responsible for selecting disposal facilities that can accept PCB wastes with this restriction. 3. If the Contractor or affiliates of the Contractor (subcontractors, subconsultants, etc.) take unauthorized samples and analyze them for total PCBs, then the contractor will be responsible for the cost of any resulting removal required under existing state and federal regulations triggered by their sampling and analysis. 4. The Owner and the Engineer shall specifically review and approve in writing a proposed testing plan prior to samples being submitted for laboratory analysis. D. In general, the following activities are minimum requirements of this Section and affect the renovations performed on building components identified and/or assumed to contain PCBs: 1. No torch cutting of PCB-contaminated building materials shall be performed. 2. No renovation/demolition activities shall occur that can reasonably be expected to increase the worker's exposure above the Permissible Exposure Limits (PEL) for PCBs unless certain worker protection is implemented. 3. Workers shall be informed of the PCB-contaminated building materials to be removed or encapsulated. 4. At a minimum, worker protection shall comply with applicable Occupational Safety and Health Administration (OSHA) standards. Worker Right to Know and Health and Safety Standards of Title 29 CFR, Part 1926, shall also apply to the work of this Section. 5. Unprotected, untrained workers or trades shall not perform any related work within or adjacent to work areas involving PCB-contaminated building materials. A.

Previously painted surfaces to be recoated: a. Steel b. Other surfaces so noted or scheduled on the Drawings c. Existing pipes, fittings and supports that will not be replaced in this Project but that will be recoated as noted on the Drawings. B. Coatings are not required for glass, stainless steel, chrome, cadmium plate or aluminum that is not in contact with concrete. C. Ventilation, dehumidification, and temperature control equipment required to provide and maintain the proper environment for worker protection and for coating application and curing. D. The Contractor shall furnish to the Owner, at no charge, for use duration of this Project, dry film thickness gauge, wet film thickness gauge, adhesion testing, surface preparation testing, temperature / climate condition detectors, electrical flaw gauge and / or holiday detection equipment.
