• The reasons for the higher design development costs as compared to the schematic design costs were identified. Some of this reflects scope changes, expressed as add alternates. • The costs include contingencies, including design contingencies. • For each school there is a base construction only cost of, $21.825 million for Clarke and $35.895 million for Diamond, plus a list of costs associated with the following: ➢ Potential add alternates, such as access road improvements, projects that address current HVAC problems, or projects that improve functionality. ➢ Projects that have previously been studied and are desired or needed. ➢ Environmental sustainability projects; it was noted that most of these do not result in any pay back, although roofs are generally being built to accommodate solar panels. • PCB removal had been identified as an add alternate to the project for some exterior window caulking. A question was asked if this needed to be done in association with the larger project or if it could be done separately. The response was that it could be done either way, but needed to be done this coming summer, so it was thought to be most efficient to have it incorporated into the larger project. • Phased construction is identified for both school buildings, with the work completed by September 2017 at Clarke and by May 2018 at Diamond. • The work at Clarke requires getting an Order of Conditions from the Lexington Conservation Commission; this should be pursued as soon as possible. • Once funding is available, the shop drawing phase should be created immediately if the projects are going to meet their target dates for completion. • The VE process must be pursued expeditiously, with a master list of potential VE items to go to policy makers. iii. General Discussion: Comments included the following: • Studies indicate that the heating, ventilation, air conditioning system is failing at Diamond. DiNisco has identified four alternatives for addressing this problem. Mr. Goddard noted that the two low cost options do not adequately address air temperature /comfort and the lowest cost option does not address acoustical issues. He noted that this project had previously been included in his routine five year capital plan. • There is a tight schedule for meeting project target dates and the cost for the CM to support enabling work, such as shop drawing preparation to properly support summer foundations and steel work needs to be identified. It was noted that this cost for CM enabling support is estimated at $150,000, and should be included in Article 2 (Appropriate for School Facilities Capital Projects) that is being brought to the fall 2015 Special Town Meeting #1 in December.
