SUMMARY OF WORKS 010100 - 1 University of Maryland Bressler Research Building – Substations 4-7 Renewal Project No: 19-312 Construction Documents December 18, 2020 1. Phase One: Clearing Space for the New Electrical Switchgear • Demolish existing roof hatch and provide new hatch. • Install a new 600amp MLO,480, 3∅,3w Motor Control Center PB (MCC-PB) on southeast wall near substation 7. Provide temporary incoming 3P, 600amp power feed from spare switch in existing Substation 7. • After new power to MCC-PB is active, provide new pull box(es) in accessible ceiling space outside of the boundary area of the new electrical room and provide new conduits and circuits from new "MCC-PB" to pull box(es). • Start turning off power and disconnect each existing circuit and rerouting them from existing MCC-PB, MCC-PD and EF-63 VFD equipment to pull box and splice to existing circuits • Relocate existing EF-63 VFD equipment to the southeast wall near substation 7. Provide new conduit and circuit from EF-63 VFD new location to pull box and slice existing circuit. • Turn off existing MCC-PB main power switch in Substation 6, MCC-PD main power switch in Substation 7 and remove existing incoming electrical feeders and conduits in its entirety. Both MCC-PB and MCC-PD equipment to be removed and discarded. • Pour new housekeeping pad for new preaction cabinet and nitrogen generator. Relocate existing combination standpipe riser, NFPA 14 Class I 2-1/2” hose outlet, and 6” zone control for Penthouse overhead wet sprinkler system. • Pipe new preaction cabinet feed downstream of new zone control and rough-in new preaction cabinet. • Wire and confidence test all fire alarm devices associated with fire sprinkler monitoring to ensure fire protection is maintained in service. 2. Phase Two: Installation of New Substations • Install new concrete pad in the proposed location of new Substations "A" and "B". • Install the new mounted double ended Substations 'A' and 'B'. Run a cat6 cable to each switchboard (and daisy-chain the 2 meters in a double-ended board). Run cat 6 cable in 1" from each meter to building network switch located in the penthouse. • Provide core drill in floor and install 2-3" conduit from HV pull box in basement Electrical Room B027 stubbed up into penthouse. • Install HV linear pull box on penthouse wall space and intercept the 2-3" conduit riser. • Install 2- 3" conduits from new Substations “A” and “B” to HV pull box in penthouse. • Install new feeders from basement Electrical Room B027 to new Substations "A" and "B" in penthouse. 3. Phase Three: Basement work SUMMARY OF WORKS 010100 - 2 University of Maryland Bressler Research Building – Substations 4-7 Renewal Project No: 19-312 Construction Documents December 18, 2020 • Open and close switches NE3 and NW3 in the existing penthouse substations 4, 5, 6, and 7 such that all substations are being powered by a single incoming feeder. • While the single incoming feeder is providing power the existing penthouse substations. Disconnect power to the other main switch and splice onto one of the new feeder cables in pull box to feed power to the new Substation "A" and "B" in penthouse. 4. Phase Four: Removal of Existing Substation 7 • Provide a new 1200amp, MLO, 480/277v,3 ∅,4w Main Distribution Panel MDP7. • Provide incoming feeders and conduits from Substation "B" to new Panel MDP7. • After Panel MDP7 is powered and active; rerouted temporary incoming feed to MCC-PB from existing Substation 7 to new Panel MDP7 (6-hour shutdown). • Provide a pull box in accessible ceiling space and provide new circuits and conduit from new Panel MDP7 to pull box. Turn off power and disconnect each existing circuit and rerouting them from existing Substation 7 to new pull box and splice to new circuits (12-hour shutdown). • After all existing circuit have been routed to Panel MDP7 and are active. Open incoming power switch at Substation 6 that feeds Substation 7 and remove the existing feeder and conduit connection in its entirety. • Remove existing Substation 7 in its entirety. Equipment shall be discarded. 5. Phase Five: Removal of Existing Substation 6 • Provide a new 1600amp, MLO,480/277v,3 ∅,4w Main Distribution Panel MDP6. • Provide incoming feeders and conduits from Substation "B" to new Panel MDP6. • After Panel MDP6 is powered and active; provide a pull box in accessible ceiling space and provide new circuits and conduit from new Panel MDP6 to pull box. Turn off power and disconnect each existing circuit and rerouting them from existing Substation
