Soil Gas Control Systems ANSI/AARST CC-1000 2018 in New Construction of Buildings 25 ANNEXES (Non-Normative) ANNEX A (Non-Normative): Inspections for compliance. Inspections for compliance are important at the following junctures for system success but shall not be required unless: a) required for exercising credit options in Section 4.3 ; o r b) specifically referenced in the adopting ordinance, contract or design requirements. Adoption: To render these inspections as required, cite Annex A or any of the following individual provisions in the ordinance, contract or design specifications. A-1 Inspection prior to closure over soil by concrete or soil gas retarders for design, materials and secure fastening: Section 5.10.2 : An inspection shall be conducted to verify all inlets and ducting are secured and that gas permeable layer materials and closed surroundings are compliant with this standard prior to placement of concrete or soil gas retarders over a gas permeable layer. A-2 Inspection prior to completion of indoor finishings in ground contact areas to verify plenum sealing and closure: Section 6.5 : Prior to completion of indoor finishings, an inspection shall be conducted to verify a continuous sealed barrier has been constructed between soil gas and airspaces within the building. A-3 Inspection prior to completion of indoor finishings to verify exhaust vent pipe compliance: Section 9.6 : Prior to completion of indoor finishings, an inspection shall be conducted to verify compliance for exhaust vent piping in accordance with Sections 8 through 9 . Inspection forms: See exhibits A-1, A-2 and A-3 for examples of appropriate inspection forms ANNEX B (Non-Normative): ASD fans required. Soil gas control-vent systems that are fan driven for Active Soil Depressurization (ASD) provide both the best assurance for mitigation of soil gas entry and the most consistent reduction in occupant exposure to hazardous soil gases. However, the installations of fans shall not be required unless specifically referenced in the adopting ordinance, contract or design requirements. Adoption: To cause fan-driven systems to be required, cite Annex B-1 in the ordinance, contract or design specifications. B-1 Fans shall be provided in accordance with Section 10 to result in Active Soil Depressurization (ASD) systems. ANNEX C (Non-Normative): Provide radon test kits. Post-construction testing is the only way to verify that occupants will not be exposed to hazardous soil gas. However, post-construction testing shall not be required unless specifically referenced in the adopting ordinance, contract or design requirements. Adoption : To ensure building owners are provided tools to evaluate hazards from radon gas, cite Annex C-1 in the ordinance, contract or design specifications. C-1 Radon test kit(s) required. A minimum of one long-term radon-in-air test kit from a certified/licensed laboratory shall be provided for the occupants of each ground contact dwelling, unit or occupancy use area.
