1. M.Lawrence gave a presentation on the new DPW facility noting that this is Dart of an 8-week process.
He said that the design was to protect the resources on site and create screens and buffers.Rain and storm
water will be directed to bio-retention areas(demonstration garden and cistern)on site.Native plants and
wildflowers will be used in the surrounding beds.
2. The new DPW facility which has a solar orientation,made of corrugated metal positioned horizontally
and insulated metal panels will be broken down into five separate spaces: central storage;two-story
administrative building(only part of the structure to have AC);maintenance;vehicle storage;and shops.
3 Natural light will be implemented with the help of skylights and polycarbonate clerestory with a high
R-factor.
4 Ouotes are coming from three structural engineers.
5. Chanter 13 Massachusetts Energy Code does not allow for insulation to go beyond a certain height.If
the vehicle storage is unheated the code does not apply
6.D Bitsko talked about the site and landscaping plans.
7 The DAC suggested softening a corner of the building facing the street.They also recommended
plantings as a screen in the employee parking area and on abutting property
8. When asked if it would be possible to have a skylight over the office areas on the second floor.HKT
explained they had thought about placing one there but rejected the idea because of problems with snow
and water.
9 The PBC emphasized the importance of views from the windows and the use of natural light.
10. The green area over the new central storage area will be used to manage storm water and collect water
that will be used to flush toilets and in street cleaners.Water falling to the pavement will be directed into
bio-retention basins.
11 The PBC asked HKT to re-evaluate the employee's entrance to the facility
12. The DAC had concerns regarding the use of salt on the corrugated metal exterior.HKT explained that
the bottom of the exterior wall would be pre-cast material with the metal above.
