AC- PAC Heating/Cooling Pipe Replacement
Emergency replacement of four (4) – six inch diameter pipes (piping system) that route from the Academic Core (AC) Building to the MGBPAC Building is required. The subject piping system provides cooling and heating from the AC Building to the MGBPAC Building and is routed underneath Guy R. Brewer Blvd. at depths ranging from 8 to 12 feet below the street level. This piping system has been repaired two (2) times within the past ten (10) years. Several months ago a 3rd failure was detected with this piping system by our plant maintenance staff and verified by CUNY Central Office contractors. A determination has been made that the integrity of the entire piping system is now questionable and warrants a total piping system replacement before the beginning of the 2015 winter season to provide heating comfort to the MGBPAC.
We will excavate a trench that is 5 feet wide by (8 to 12 feet) deep from the AC Building, across Guy R. Brewer Blvd., into the "Handicaped" parking area, make a right turn pass the Guard Post; then finally make a left turn over to the MGBPAC Building.
Once the trench is fully exposed we will remove the old piping system, replace it with a new piping system, and then backfill the trench with the excavated material.
The existing designated MGBPAC "Handicaped" parking area will be temporarily modified by removing the first two (2) handicap parking rows and designating these two (2) rows for the staging area. We will also temporarily shift, in the easterly direction the two (2) Public Safety parking spaces and ten (10) Reserved Parking spaces along the LIRR wall by ten (10) car spaces. The 3rd and 4th rows of existing "Handicaped" Parking spaces will not be altered and will be 100% available for usage during this emergency repair work. All associated parking signage (Handicaped, Public Safety and Reserved) will be adjusted as needed.
Please see illustration sketch below.
