The HUD Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing (July 1995), chapter 7- These guidelines address paint chip collection in housing units and laboratory analysis. It also addresses commonly encountered interior painted components that should be tested. It is anticipated that a blend of these noted guidance documents will provide the basis for sampling strategy, testing and reporting. As a result of the testing, a risk assessment or EBL related testing may be warranted to address the conditions and steps necessary to mitigate any damaged painted surfaces found. Dust wipe sampling and soil sampling will be performed in accordance with HUD Guidelines, Sections 13.1 and 13.3 respectively. Recommendations Cost Effective Treatments and Specifications for Lead-Based Paint Materials. As part of the process or during various milestones of the different projects, The Bainbridge Group tracks all on-going projects for construction cost as well as design elements affecting the cost of the project. The Bainbridge Group has developed realistic budgetary estimates within the City's needs and monetary outlay. The Bainbridge Group maintains and updates a database of construction costs for all in-house and other public projects for future reference. The database has been instrumental in the performance of cost estimation and budgeting of projects. During these reviews, The Bainbridge Group is able to identify the areas where costs can be saved. This process allows both the designer and the City to identify the pros and cons of any potential changes that may warrant other recommendations or modifications. Also, in order to avoid high costs, cost overruns or unnecessary change orders - different treatments may be recommended depending on the existing condition and make-up composition of the finish materials, building components and/or substrate materials. There are several cost effective methods that are recommended as interim controls in housing components where total paint removal is not required of is not cost effective. They are the following: Paint Film Stabilization Eliminate any exterior leaks in the building envelope (e.g., roofing leaks, gutter or downspout problems, missing or damaged doors, roof flashing, missing trim, missing glass in windows, defective or missing caulk and glazing, et.) Eliminate any interior water leaks (e.g., plumbing leaks, inadequately ventilated attic spaces, windows that won't close completely, missing grout or caulking, etc.) Select and implement an appropriate work site preparation level. Prepare surface by wet scraping or wet sanding all loose and peeling paint. Clean, de-gloss, and neutralize all surfaces After all surfaces are dry, apply encapsulant designed for lead-based paint as a primer coat.
