Lexington Permanent Building Committee 13 September 2012 4.0 Bridge & Bowman Renovation Projects 4.26 Roof Top Unit screening 11/2/11 It was reported that the roof top hvac equipment would be larger than originally anticipated and could be 18 inches to 2 feet taller. There was some concern expressed over the aesthetics of the larger units and the overall view of the school to the public, notwithstanding any sound abatement concerns. Various options for screening and placement of support structure for future screening were discussed. Currently six units suspected of a need for screening based on sound abatement were modified to include roof reinforcing for future screen panels. It was discussed to increase this count to 10 to include units where screens may be desired for aesthetics as well; however this motion was not acted upon, leaving just the original 6 locations 12/8/11 This issue was again discussed and the PBC elected to request a unit price be added to the bid submission for adding the steel support to other RTU locations if the town elected to do so during construction. 1/19/12 Initial feedback from architect was that they did not want to include a unit price for additional RTU locations, but they later agreed to do so. 6/28/12 DPC discussion cost for additional superstructure improvements for additional screening at roof top equipment cost $35,000. Discussion on schedule impact, cheaper now than later, other cost items are out there, abatement elbows +/- $70,000 claim was submitted but denied. Motion to approve structural support for 1 additional roof top unit screen not to exceed $35,000 with no change in duration.
