Call to order at 7:05 M. Barrett handed out the Meeting Minutes from the 5/5 and 5/11 PBC Meetings, which the Committee agreed to table until the next scheduled PBC Meeting on 6/14 for further review. 2. Review of Project Estimate D. DiNisco began by explaining that a good portion of last week was spent reviewing the estimates from both A. M. Fogarty (third party estimator), and Walsh Brothers, adding that they will be carrying building itself has not shifted from a cost perspective, but there are many characteristics to the site which create a challenge, and in turn increases cost; some of these characteristics being the topography, storm water management parameters, need for large retaining walls, etc. D. DiNisco went on to say that the estimates were close to a 7% difference at the end of the day Friday, adding that the project team has spent a lot of time reconciling. Furthermore, she stated that Walsh wanted a couple more days to fine-tune some of their numbers, and added that she is confident they will get to a number that is agreed upon. Additionally, D. DiNisco explained that the project team had begun to put together a VE Log to bring the number down; they had gone through a series of adjustments to simplify some areas of design to be more cost effective. One major adjustment that is currently being explored is a ~15% rotation of the building away from the abutter property lines, which could allow them to avoid any easements, perform a smaller amount of blasting, and less of a retaining wall on the north side of the property. The Committee then began to review the VE items, and D. DiNisco reassured that none of these items would affect the educational program, maintenance, operations, or function of the building; she added that most of them After being asked why the cost of geothermal went up so much since the PSR, the project team explained that after further exploration of the site and geothermal well systems, it became apparent tha expensive than the deep wells upfront. D. DiNisco pointed out that they would have a life cycle cost analysis soon. The original $600,000 Geothermal Design was based on a deep well (1,500+ foot) Open Loop System similar to those in other Lexington schools, after engineering review it was determined that system was not appropriate for the Hastings Project but that a shallower (500 foot) Closed Loop System was the best fit for the Hastings Project, which led to a 100+/- well design configuration and a $2.3 million dollar system cost. A test well was authorized and dug to confirm the engineers findings and it was determined that the closed system would work for the project. The Committee then discussed the option of the Haul Road, giving access to construction vehicles during construction. D. DiNisco pointed out that Walsh believes the Haul Road could come as a savings to the project, as it would allow for larger construction vehicles to access the site for deliveries, resulting in less deliveries, which cost money. There was a discussion regarding the requirement of a police detail if the Haul Road were to be put in place, and D. DiNisco reported that the project team is currently exploring this option in further detail. The Committee and project team all agreed that the Haul Road would be worth if from a cost standpoint, and the project team will report back with their findings. The Committee then reviewed the remaining items in the VE log, agreeing to take several of the items now and leaving the rest of the items for discussion down the road, the total value of the Value Engineering taken was $1,445,370. G.1, G.3, G.4, G.6, G.7, G.14, B.1, B.2, B.6, C.1, C.2, C.4, C.6, C.7 D. DiNisco and T. Elmore then explained that this list will continue to grow and will be much larger by the time they go out to the voters, though this was a successful first pass in finding savings. D. DiNisco added that the VE Log will also be included with the cost estimates in the submission to the MSBA. The Design team has taken design benefits and lessons learned from the Estabrook Project and incorporated them into the Hastings design. Motion to Adjourn by D. Perry 2
