20 Merrill Green Stadium Renovations September 4, 2015 Addendum #1 PROJECT DESIGN FOR ASBESTOS REMOVAL 1. SCOPE: The work covered by this section includes furnishing all plans, labor, equipment, materials, and transportation necessary for the proper and safe removal, handling, and disposal of non-friable materials. 1.1 Remove asbestos-containing materials to include the following: Approximately 700 square feet of asbestos containing residual floor mastic under carpet, 15 square feet of floor tile and mastic and 2800 square feet of wallboard with joint compound. 2. TERMINOLOGY 2.1 Abatement - procedures to decrease or eliminate fiber release from precast, spray-on, trowel-applied asbestos-containing building materials. Includes encapsulation, enclosure, and removal. 2.2 Air Monitoring - the process of measuring the fiber content of a specific volume of air during a stated period of time. 2.3 Airlock - system for permitting ingress or egress of personnel without permitting air movement between a contaminated area and an uncontaminated area, typically consisting of two curtained doorways at least three feet apart. 2.4 Amended Water - water to which a surfactant has been added. 2.5 Asbestos - a general term used to describe several fibrous mineral silicates. Although there are many asbestos minerals, only six are of commercial importance. They are: Actinolite, Amosite, Anthophyllite, Chrysotile, Crocidolite, and Tremolite. For the purposes of this Project the term "asbestos" is used interchangeable with "asbestos- containing sprayed material", "dust containing asbestos", and "friable insulating material containing asbestos". 2.6 Asbestos Control Area - an area where asbestos removal operations area performed and which is sealed and isolated by physical barriers to prevent the spread of asbestos contamination. 2.7 ANSI - American National Standards Institute. 2.8 ASTM - American Society for Testing and Materials. 2.9 Clean Room - an uncontaminated area or room which is part of the worker decontamination enclosure system, with provisions for storage of workers' street clothes and protective equipment. Also known as the "Change Room" Critical Barrier - seal applied to openings connecting the abatement area with adjacent spaces that will not be included in the containment.
