During these repairs <br />areas of leakage were discovered in several secondary components that will require an <br />underground access for component replacement or repair not discovered or included in <br />the original proposal. The following information is provided that will outline those <br />construction type repairs for each tank system. This work will require plans, permits <br />and approval by the Santa Ana Fire Dept. <br /> <br />o <br /> <br />EMERGENCY GENERATOR TANK SYSTEM <br />The 3" secondary piping termination at the diesel turbine sump upon removal of the old <br />piping test boot was found with a crack extending outside tha containment sump. This <br />pipe end was tapered rather than flush cut during construction. A tapered pipe end is <br />used for insertion into a connectOr. It will be necessary to Excavate outside the <br />containment sump to this supply piping secondary to replace the piping immediately <br />outside the sump. For this proposal up to five feet of piping is assumed to be replaced. <br />Additional piping if replacement is required will be quoted and work completed with <br />clients written approvi'll only. <br /> <br />c <br /> <br />Scope of Work <br /><> Generate plans, applications and submittal package to ClJPA and City of Santa Ana <br />concerned regulatory agencies; obtain permit approvals <br /><> At the turbine sump area saw cut concrete on the supply piping side of containment <br />sump. Break out concrete, remove and haul away. <br /><> Hand dig, excavating to expose the affected broken secondary piping. <br />Q Remove up to 5' of broken piping <br /><> Provide and install new 3" sump penetration entry fitting <br /><> Disconnect supply line piping at turbine sump to install same length of removed 3" <br />secondary piping. <br /><> Reconnect primary supply line. <br /><> Install test boot and pressure test entire secondary to corlfirm integrity <br /><> Conduct hydrostatic testing on sump to confirm integrity. <br /> <br />951.677.0704 Fax 951.698.5436 888.203.5944 <br /> <br />ATTACHMENT 2 <br />
