Lexington Permanent Building Committee 14 June 2012 ECC was invited to the 4/26/12 PBC meeting to evaluate comparative data on Mechanical system options and energy model updates. While only one member of the ECC was available for the meeting the Mechanical consultant was equally not able to provide the documentation the facilities department was seeking. Updated material was requested from the engineer and Pat G. will work with ECC to reach consensus on systems. Designer briefly updated PBC on continued discussion of materials for fagade and general design features and building elevations. PBC requested cost comparative data for limestone and similar materials proposed. DDP stated that the next working group meeting would included continuation of design discussion. 7.35 Collaborative Partners Update for 4/26/12 4/26/12 Joe R. introduced members of the Shawmut team and provided a brief update on the status of estimating which included Shawmut's first pass at an estimate on the project. CP was in the process of comparing the Shawmut estimate with that of the schematic design and it was not ready for full discussion. PBC requested a systems summary estimate and Shawmut agreed. 7.36 Collaborative Partners Project Update for 5/10/12 5/10/12 Joe Riley discussion on Cost estimate comparative of Shawmut estimate and schematic design estimate. Next Friday (5/18/12) is deliverable for DD estimate and reconciliation is scheduled for two days 5/20 and 5/21. Cost Estimates to be discussed in more detail at next 5/24/12 PBC meeting. • PBC discussed location of CM trailers would prefer to place them inside the fence. • Question is there - Fence on top of retaining wall. • Meeting with Fire Dept. and Building Inspector on 6/1. • Met today 5/10/12 with Building Inspector and reviewed site logistics fully for building permit for retaining wall. Building Inspector ok with foundation permit. • Met with Shawmut and abatement contractors to walk through building. Shawmut will obtain numbers for abatement for contractors to validate estimate. • Met with Commissioning Agent and working on Owners Project Requirements with Pat. Process is underway. • Meet with Hartwell Ave staff to talk about exporting site materials, environmental services and possibility importing fill materials from Hartwell Ave. • Shawmut working with Electric utility on temp power and new service issues. 7.37 DiNisco Update 5/10/12 5/10/12 DiNisco reviewed/ update Building Elevations and Interior Design features of classrooms, hallways, cafeteria, gym, acoustical deck in gym and cafeteria and tectum panels in gym. Gym floor linoleum product. Reviewed samples of gym floor products preference is for linoleum. Waiting for test data on bounce factors. Reviewed samples of rubber and linoleum for hallway and classroom floors. Rubber in stairs and linoleum throughout building. Waiting for test data for sound deadening. Estimated 23% savings on energy but lowering gas prices are dropping our percentage savings to 19 % + / -. LEED requires 20% minimum cost savings. Waterless urinals are being looked at for additional savings, which save 40,000 gallons of water per year on 1.2 gal /flush. DiNisco working and confident in meeting LEED Silver. Pat Goddard advised that ECC met recently and reviewed updated mechanical system information and energy analysis data from RDK. The ECC requested additional information but supported that decisions made to date were appropriate.
