14、ng radon zones.For new construction in Zone 1 areas as defined on “EPA Map of Radon Zones“, passive radon mitigation systems should be incorporated into the original building design. The design should include provisions to permit installation of exhaust fans, if necessary, after testing the building
15、 under occupied conditions. Criteria for radon mitigation SECTION 31 21 13 Page 3Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-in new construction is specified in EPA 625-R-92-016, (1994, Third Printing with Addenda) “Radon Prevention in Design and
16、 Construction of Schools and Other Large Buildings“.Materials (aggregate for capiliary water barrier and poly(vinyl chloride) (PVC) pipe) currently in use for constructing new buildings, when properly arranged as indicated and specified in EPA 625-R-92-016, will provide a passive radon mitigation sy
17、stem. A separate specification section on radon mitigation for new construction seems unnecessary considering the materials are addressed in Division 02 and Division 15 sections and the installation will be shown on the drawings.*NOTE: In most cases the work for this project will be performed by sma
18、ll business Contractors with little or no sophisticated drawing resources. Therefore, the design requirements are very minimal with respect to the production of drawings.A simple, effective, efficient, and economical radon mitigation system is little more than a PVC vent pipe (one suction point) exh
19、austed to the atmosphere without a fan (passive system). For large areas requiring mitigation, the system could include several vent pipes connected to a single outlet with an appropriately sized in-line fan (active system). Depending on the distances between suction points, several individual vent
20、pipes with or without in-line fans may be more practical.This guide specification provides criteria and material requirements for diagnostic testing, designing and constructing radon mitigation systems, post mitigation testing and constructing gypsum wallboard enclosures to conceal the radon mitigat
21、ion systems in occupied spaces.*DRAWING INFORMATION REQUIREDNOTE: Prepare A4 (297 by 210 mm) 8 1/2 by 11 inch scaled drawings for each building and include at the end of this section. Depending on the building size, several drawings may be needed to show the entire building in legible scaled size.A
22、blank drawing with sample title block is included at the end of this guide specification. Include the information for identifying the project and radon mitigation system designer and leave blank.For each building requiring radon mitigation provide the following information:SECTION 31 21 13 Page 4Pro

Identify suspected or confirmed entry points of radon into the buildings such as exterior wall separations from floor slab, large cracks in floor slabs, floor drains, and exposed earth in crawl spaces.6. Identify and locate hazardous materials such as lead based paint, vinyl asbestos floor
