RFP No. 18.043 A2—Hazardous Materials Surveys federal regulations, using industry standard chain -of -custody procedures. All field activities are recorded on field forms designed by Ninyo & Moore for hazardous building materials surveys. Asbestos analysis is performed by an accredited laboratory in the National Voluntary Laboratory Accreditation Program for bulk asbestos fiber analysis. Lead surveys using the portable XRF anaylzer, provide immediate results In milligrams per square centimeter (mg/cm'). Quality assurance or confirmation paint chip samples are collected in the field and analyzed by a laboratory that participates in the EPA National Lead Laboratory Accreditation Program. Sample results are reviewed by Ninyo & Moore personnel in accordance with our Quality Assurance Program which facilitates compliance with project performance standards, schedules, and budgets. This comprehensive program is outlined in our corporate Quality Assurance Program manual that describes specific quality control procedures to be used during projects. The program addresses data generation, management, and quality assessment guidelines for sampling and analysis procedures, as well as methods of abatement and corrective action. The hazardous building materials surveys provide Information on locations, quantities, and condition of the materials. Photographic documentation and site maps are used to easily identify the materials. The surveys can also be used as part of the construction contract documents so that contractors can estimate abatement costs. Hazardous building material surveys will be summarized into one deliverable document per project site or as requested by the City. The survey reports provide a descritpion of the project site and buidings, document the project field procedures and results of the surveys including sampling descriptions, field drawn sample locations found to be either asbestos or lead containing, condition and estimated quantities of ACM and LBP, laboratory analytical reports and chain -of -custody documentation, photographic documentation, findings, and recommendations for abatement. Special Concerns: • The City should anticipate asbestos containing piping may be encountered in the subsurface during some demolition and reconstruction projects. It is very common for asbestos piping (trans- its) to be found during excavation and grading activities. For abatement of uncovered subsurface transits piping, a specific Procedure 5 Plan is required in accordance with SCAQMD Rule 1403, Ninyo & Moore has in depth experience preparing the Procedure 5 Plans on a rapid schedule and works closely with the SCAQMD on finalizing these plans to mitigate construction delays. • The City should also be aware of a Federal NESHAP regulatory requirement which is being en- forced by the SCAQMD. If one sample of a homogeneous material contains an asbestos content of greater than one tenth of 1 percent (>0.1 percent) but >1 percent, it cannot be identified as asbestos containing construction materials (ALCMs) unless confirmed by additional polarized light microscopy (PLM) point count analysis. If the initial PLM result is less than one percent, and PLM point count analysis is not performed, then the material is required to be treated as an ACM (>1 percent). There is great value to the City by performing the additional PLM point count analy- sis as needed based on preliminary results. • For larger project sites, the City may consider having Ninyo & Moore prepare abatement bidding specification documents based on the results of the surveys. Surveys document all hazardous materials present (asbestos, lead, and universal wastes), but all hazardous materials may not be legally required to be removed from the structures. Providing contractors survey results without providing bidding specifications could results in unnecessary costs to the City. Ninyo & Moore is highly experienced in preparing these documents and provided them to the City on the repre- sented YMCA renovation project.
