Renovation of a municipal facility in Rochester, Vermont. Completed plans call for the renovation of a 1,800-square-foot municipal facility.

Question Deadline 06/03/2026 Questions may be submitted to Harry Falconer at hfalconer@trorc.org. This work consists of construction of building envelope improvements (insulation/air sealing) for the Rochester Town Office Building at 67 School Street, Rochester, VT. Before submitting a proposal, bidders shall examine the town scope documents, visit the work site if necessary, and fully inform themselves as to all existing conditions. Construction must be completed by 15 November 2026. Air Seal Attic and Replace Insulation The attic space is currently insulated with approximately 5" of blown fiberglass insulation and an additional 12" of fiberglass batt insulation on top. The plaster and lath finish above the ACT ceiling in the finished space is acting as the air barrier, however the plaster is in poor condition and no air sealing has taken place at top plates of interior or exterior walls. The attic space is approximately 30' x 60'. The insulation is to be replaced, and air sealing to be implemented. 1. Materials a. Foamed-In-Place Insulation: Closed cell polyurethane foam. i. Shall have a minimum R-value of 7.0 at 1 inch thickness when tested in accordance with ASTM C518. ii. Shall utilize a blowing agent of water or non-ozone-depleting gas. iii. Shall have a maximum air permeance of 0.02 cfm per square foot when tested in accordance with ASTM E2178. iv. Basis of design material is Carlisle Spray Foam Insulation; Sealtite Pro HFO. Equal substitutions will be considered. b. Cellulose Insulation: Loose Fill i. Shall have a minimum R-value of 3.7 at 1 inch thickness when tested in accordance with ASTM C518. ii. Basis of design Installation a. All existing attic insulation is to be removed and disposed of by contractor. b. After fiberglass insulation has been removed, a flash coat of foamed-in-place insulation, approximately 1 inch thick, shall be applied across the attic floor. i. Contractor shall inspect substrates prior to installation to ensure it is adequate to accept material. ii. Foamed-in-place insulation shall seal all ceiling penetrations and top plates from interior and exterior wall framing. iii. Insulation shall be installed in accordance with manufacturer's written instructions. c. After Foamed-in-place insulation has been completed, attic space will be prepared to accept cellulose insulation, including but not limited to the following: i. Construct appropriately sized plywood or OSB insulation block around the existing attic hatch. d. After attic space has been fully prepared, loose fill cellulose insulation shall be installed at a depth of 14 inches to achieve approximately R-60 in the attic assembly. i. Insulation shall be installed in accordance with manufacturer's written instructions. e. Existing attic hatch approximately 30 inches by 30 inches shall be upgraded to include the following: i. Perimeter weather stripping/foam gasketing between the hatch panel and trim edge. ii. (2) barrel bolt style latches for each side of the hatch to ensure a tight seal when closed. iii. 10" of expanded polystyrene board insulation to achieve a minimum of R-50. Foundation Insulation A large portion of the concrete foundation is exposed above grade on the east, south, and west side of the building, leaving a large surface area vulnerable to heat loss due to low R-value. The intent is to introduce exterior rigid insulation to these areas with appropriate water management and protection finishes to ensure longevity of the system. The thickness of the insulation may vary from 1.5"-2.5" to align with the existing trim board, and the height above grade varies from approximately 3' to 7.5'. The estimated surface area above grade is approximately 630 SF. 1. Materials a. Graphite Polystyrene Insulation i. Shall have a minimum R-value of 5.0 at 1 inch when tested in accordance with ASTM C518. ii. Basis of design material is BASF Neopor F5000. Equal substitutions will be considered. b. Finishes i. May be one of the following finishes as selected by the Owner. 1. Stucco finish with base coat and reinforcing mesh. 2. Alternative options presented by the contractor will be considered. c. Accessories i. Foam Board Adhesive (ex. Loctite PL 300) or mechanical fasteners with washers 2. Installation a. To minimize the disturbance to the site, only above grade insulation is being proposed. No excavation below grade is required. There is also some evidence of below grade insulation already in place. b. Existing foundation surface shall be properly prepared to accept insulation. c. When possible, materials such as wiring or piping should be moved to allow for insulation installation along the foundation. For materials that cannot be relocated, insulation shall be cut to fit tightly around these objects. Infill Unused Basement Windows Along the west elevation of the foundation there are two (2) windows, approximately 30" x 30", which have been temporarily covered with rigid insulation. These windows are no longer used and are to be infilled prior to the installation of the foundation insulation. 1. Materials a. Quikrete bagged concrete or similar b. Concrete masonry units & appropriate grout 2. Installation a. Contractor shall remove and dispose of existing windows. b. Opening shall be cleaned and prepped to accept concrete or block infill c. Infill shall be completed to leave a smooth finish on the interior and exterior, in alignment with the existing foundation. Meeting Room Door Replacement The exterior door located at the west elevation was found to be in poor condition and allowing significant air leakage. This door is to be replaced. 1. Materials a. Insulated Steel Pre-Hung Exterior Doors i. Basis of design is Jeld-Wen 6-Panel Steel Prehung Front Door. Equal substitutions will be considered. ii. Doors shall have a maximum U-Factor 0.20, equivalent to R-5. iii. Hardware type and finish, interior finish, and exterior finish to be approved by Owner prior to ordering. b. Door Accessories i. All door installation accessory materials including but not limited to flashing tape, flashing membrane, sealants, and fasteners shall be in compliance with manufacturer's written instructions. 2. Installation a. Existing exterior person door and frame shall be removed and disposed of by the Contractor. b. Door and frame size shall be measured by contractor to fit in existing rough opening. c. Rough opening framing shall be inspected and confirmed acceptable prior to door installation. Any framing at the door opening in poor condition shall be replaced prior to installation. d. Doors and frame shall be installed level, plumb, square, and in accordance with manufacturer's written instructions. Air sealing and water management practices shall also be installed per manufacturer's instructions. e. After complete door installation, interior and exterior wooden trim shall also be installed. Finish to be approved by Owner. Air Seal Exterior Wall Outlets Electrical outlets and switches on exterior walls were identified as a source of air leakage. Outlet covers are to be removed and foam gasketing installed to reduce this air leakage. 1. Materials a. Foam Electrical Outlet/Switch Weather Proofing i. Foam gasketing appropriately sized to fit around electrical outlets and switches, creating an air tight seal behind the cover plate. ii. Basis of Design M-D Building Products Foam Weatherstrip Sealer for Outlets and Switches 2. Installation a. All electrical cover plates on exterior walls throughout the building (1st and 2nd floor) are to be removed. b. Appropriately sized foam gasketing is to be installed around outlets and switches. c. Cover plates are to be re-installed. Improve Air Seal at Interior Window Inserts Interior window inserts are currently installed in the windows located in the meeting room on the west end of the building. These inserts do not all create a continuous air sealant around the window framing. We recommend replacing the foam gasketing with a new material with better expansion properties. 1. Materials a. Window Sealant Tape i. Self-expanding perimeter seal tape sized to fit around the perimeter of the interior window inserts. ii. Basis of Design Sika EMSEAL Multi-Use Sealant Tape 2. Installation a. Existing foam gasketing around the perimeter of the interior window inserts shall be removed and disposed of by contractor. b. Perimeter of window inserts shall be cleaned, with all dust and residue removed to allow for proper tape adhesion. c. Sealant tape shall be cut to the appropriate length around the perimeter of the window inserts. d. After sealant tape is installed, window inserts shall be re-installed in window openings to allow for the sealant tape to expand and create a continuous seal around the window framing.
