Radon mitigation companies must utilize licensed electricians, plumbers, salespeople, and other professionals for all applicable components of the work rendered. The Contractor shall also provide the owner a guarantee/warranty that the system installed shall maintain indoor radon levels below 2.0 pCi/L for a minimum of 10 years.

B. These Specifications govern all work activities related to radon mitigation. All activities shall be performed in accordance with, but not limited to, the current revision of the American Society of Testing and Materials (ASTM) Standard Practice for Installing Radon Mitigation Systems in Existing Low-Rise Residential Buildings (ASTM E2121), the EPA Radon Mitigation Standards (RMS) (EPA 402-R-18-003), the ASTM Standard Practice for Radon Control Options for the Design and Construction of New Low-Rise Residential Buildings (ASTM E1465), the EPA Radon Prevention in the Design and Construction of Schools and Other Large Buildings (EPA 625-R-92-016), the American National Standards Institute/American Association of Radon Scientists and Technologists (ANSI/AARST CC-1000, ANSI/AARST RMS-LB) and all applicable federal, state and local building codes.

C. The work shall include the installation and activation of sub-slab depressurization systems as identified on the Contract Plans and Specifications.

Projected areas for potential suction pit and vent piping location include the lower mechanical and/or upper storage basement areas, as depicted on the attached site sketches. Contractor shall perform sub-slab pressure field extension communication tests to ensure pit location(s) will achieve system performance goals throughout the entire slab area.

Where work involves post-tensioned slabs, Contractor shall x-ray and/or scan floor slab in all areas where slab penetrations are to be made to locate post-tension cables, rebar, conduit, pipe, etc. and ensure items are not hit/damaged during drilling/penetration of slab. Intent of mitigation system is to reduce indoor radon levels to below a maximum of 2.0 pCi/L. Contractor shall install the SSD system as an active set-up and shall supply the fan and all related materials. Fan location is to be exterior or within unoccupied/unconditioned attic spaces with vent piping exhausted through the roof, as directly above the suction pit as feasible, minimizing any bends in and total length of vent pipe runs from pit to exhaust.

Additional Notes: Any exhaust piping that is visible within interior areas shall be boxed-in using sheetrock, then taped/prepped and painted to finish. An access door shall be provided for the air flow/pressure monitor and shall be labeled to properly identify the location of the system performance monitor.
