A detailed breakdown of estimated project costs is included as Attachment B . Phase C — AST Installation Activities Phase C includes project activities associated with permitting and inst 1 P g a laltion of the IRC-provided 6 , 000-gallon ConVault AST which will be placed by IRC on the recently constructed concrete pad . Project work will involve the installation of required underground double-walled piping runs and monitoring equipment from the ASST to the emergency generator and a spare piping run to be installed for a future AST . The AST installation activities will be completed by FECC , a licensed pollutant storage systems contractor (PSSC ) , with oversight of the installation work by GeoSyntec . Due to the uncertainties associated with AST installation activities , a 15 percent contingency has been added to the subcontractor task cost . The contingency is in place to cover items such as increased piping runs based upon subsurface conditions , inability to use some of the existing UST leak monitoring equipment , etc . GeoSyntec will notify IRCDUS of any field conditions that may require accessibility of contingency fees . GeoSyntec ' s proposal assumes three days of oversight for field activities associated withl the AST system piping, which includes a final check-out inspection and the preparagIon of as - built drawings . A detailed breakdown of estimated project costs is included as Attachment B .
