Community Center -
Representatives from the Mechanical, Electrical and Plumbing Engineers, The Maricor Group, for the Community Center project gave a presentation to the committee on the heating system for the new building. The architect is proposing to use a heat pump system, which will allow a flexibility to provide heat as necessary in the various sections of the buildings. Three types of heating systems were reviewed: Chilled Water/Boiler with Fan Coil units and baseboard heat, packaged rooftops DX Units (RTU), Water Source Heat Pumps (WSHP). The RTU's and the WSHP's were compared for Building Energy Performance - the first costs were comparable in price the WSHP's were slightly less expensive than the RTU's for annual energy costs, The WSHP's were more expensive in the winter to run, however they are much more efficient during the summer for the cooling season. The schematic design system showed that there would be approximately 42 pumps in the building. Some of the larger rooms would have multiple pumps to control the temperature in these rooms. There would be multiple thermostats throughout the building. Resident Paul Linehan asked questions about the heat pump system, he agreed with the selection of the water source pump system in many regards, however, he stated that he felt that the system draws the heat of the room from the warmer portions rather than from the floor and the floor area is always chilly. There might be some issues with noise. He also felt that there were also concerns with maintenance of the system with the replacement of the filters. He suggested a hard ducted system to address this issue. The committee felt that the ducted return systems were the most beneficial to the air quality in the building. An emergency generator would supply energy to the boiler in the event of a power failure. A monitoring system could be installed. Member Wolk asked if the system would qualify for any of the energy rebates. The MEP designers stated that they will review all rebate programs available and are designing energy efficient systems. There was discussion regarding temperature controls and human error. There was discussion regarding programmable thermostats. Norma Fitzgerald stated that she wanted multiple controls and she wanted to be sure that the seniors were kept warm. The units would be set to the water inside the loop to determine if heat was needed rather than the outside air temperature. This would be a public job and we would need to know that three vendors could supply this unit. The operation of the heating system will need to be kept simple.
The lighting fixtures and style would be provided to the committee for review. There was discussion regarding florescent lighting. NSTAR will be contacted regarding rebates. Ken Wertz suggested that the control system be kept simple.
Middle School Project:
Bonne DeSousa gave an overview of the project. The work on this project is approximately 40% complete. The committee reviewed the project schedule. A coordination meeting is scheduled for next week. About 90% of the ceiling grids have been installed in the "A" wing. The ceiling tiles will not be installed until the wall penetrations have been patched. This will be a very expensive change order if it is done by Fraser Engineering. A sleeve is not necessary for the CAT 5 wiring. There was discussion regarding the scope of work for the patching. The architect was asked to have Fraser provide a proposal for patching the walls. There was discussion among the committee members that this patching was not covered under this project because this is not a renovation job but a specific project related to heat replacement. The connectors are nearly complete and water tight.
CCD # 4 - The boiler room trim change order is nearly complete for boiler # 2 - (boiler # 1 is scheduled to be done in February). The general contractor is disputing the value of the dollars in the GGD estimate.
CCD # 5 - does not include the cost for the Johnson Controls - The CCD was for piping only. The bypass valve needs to be added for phasing.
The contractor is asking for to work on school vacation days October 4th, 5th and October 13th.
The committee discussed the ceiling units in the front hallway. The units can be raised easily. KBA will do a proposal to raise these heat units in the front soffits.
Security - The committee discussed the close-out procedures for the Clerk of the Works. The clerk checks each exterior door and drives around the building to insure that all the windows are closed.
The COP Meeting is scheduled for September 13, 2005 at 4PM in the Community Center Trailer.
MOTION: To approve Fraser Requisition # 3 in the amount of $748, 911.84 (Wolk/Waugh - unanimous)
Roof Project:
The committee directed the Architect submit a design proposal for the Roof project. The committee asked if this could be provided to the committee at the next meeting on September 13th.
East Elementary School Close-Out items:
The committee discussed the punch list and the following list of A/E omissions which include: gym thresholds, fresh air make-up unit and enlargement of the doorway at the top of the stairs.
Cottage Street School Close-out items:
Randy Smith, CMS, gave an overview of the progress of obtaining the prices for the punch list items. He stated that he has received prices based on a time and materials quote with no maximum amount given. The committee discussed if they could award work based on T & M without a maximum amount stated. There was discussion regarding the pricing on the work being priced at regular time and the work would need to be completed on premium time. He is awaiting pricing on the electrical work and construction work. The construction work has not been priced out. Names of additional contractors were given to Randy to contact on the electrical and construction work. He will report back to the committee at their next meeting. The roof leaks and water proofing for the elevator shaft has been complete. The overlay and top coat has been completed.
MOTION: To approve the KBA invoice Middle School Design - $65,000 (Waugh/Wolk – unanimous)
Respectfully submitted,
Maureen R. Doherty
