Determine size, location, and configuration of radon mitigation systems to continuously maintain radon levels under 4 picocuries per liter (pCi/L) for the housing unit. INSTALLATION: New system shall be completed using active soil depressurization (ASD) techniques and employ sub-slab depressurization (SSD) methods. All installed exterior hardware and components shall be corrosion resistant suitable for coastal marine environments. Provide electrical wire from new suction fan to existing circuit breaker panel board. New interior conduit shall run above ceiling as much as possible. ASBESTOS AND LEAD BASED PAINT (LBP) SAMPLING RESULTS: Applying 40 CFR § 763.83 Homogeneous methodology (similar construction year, unit type/model, surface material, thermal system or miscellaneous material that is uniform in color and texture). All LBP samples are less than 0.5% lead by weight and Asbestos detected on 4 of 64 units, see para 1.8 and attachment test/sample results from current and past data’s. RESTORATION: The Contractor shall restore all excavated and damaged areas to same as existing adjacent surface. POST TESTING: Following the installation of radon mitigation systems, perform radon tests in each unit in accordance with EPA Guidance (EPA 402-R-93-003). The radon test shall be a continuous monitoring system which will measure the radon levels over a minimum period of 91 days. NO POST MITIGATION: Additional mitigation work following the Post Testing is not required on this contract. Preparation of Final Report: Upon completion of the installation work, the Contractor shall provide a final report summarizing all field activities including conclusions and recommendations. In addition, the Contractor shall provide (either as an appendix to the final report or a separate report) operations, maintenance, and warranty information on installed systems. Include detailed photos of pre-existing conditions, work performed, and final conditions. Photos shall include unit numbers and written descriptions, as necessary.
