EXISTING ROOF CONSTRUCTION: GYMNASIUM (ROOF AREA "A" - APPROX. 11,165 SQ. FT.) o Steel purlins with a 1/12 slope from center to edges o 8" batt insulation o 2-1/2" galvanized metal deck (gauge unknown) o 1" perlite insulation (confirm thickness) o Modified bitumen roof membrane SCOPE OF THE WORK (GYMNASIUM ROOF) - ROOF RECOVER: Recover the roof system across the entire upper roof. This work will include the following activities: a) Remove and dispose of the 4" cant on the wall adjacent to ROOF AREA "B". b) Remove the existing roof membrane and 1" insulation (confirm thickness) from the areas identified as wet in Roof Asset Management's 01/11/23 Infrared Scan (EXHIBIT 1); inspect for moisture damage beyond the limits shown on the Infrared Scan. Carefully document the total square footage off insulation to be replaced in order to determine the final quantities required, for reconciliation of Unit Prices upon completion of the project (see SECTION 01220: UNIT PRICES). c) Replace removed 1" insulation with 1" flat polyisocyanurate insulation. Subject to a pull test (arranged for by the Contractor, with a report provided to the City and to RAM), mechanically attach new flat 1/2" polyisocyanurate cover board through the insulation to the metal deck, using induction welding fasteners and plates. Remove and replace wet tapered insulation in the cricket adjacent to ROOF AREA "B" (see ROOF PLAN). d) Mechanically attach 1/2" cover board to the east face of CMU wall around ROOF AREA "B", using drive pins and disk plates. e) Fully adhere 60-mil PVC to cover board to the face of the CMU wall adjacent to ROOF AREA "B", using solvent-based adhesive (see DETAIL XXXX). f) Remove, dispose of, and replace all rotten or otherwise unsuitable wood blocking at roof edges. Carefully document the quantity of new blocking required, for subsequent reconciliation of Unit Prices (see SECTION 01220 - UNIT PRICES). g) Re-install and flash-in all roof-mounted equipment and accessories affected by the roofing process. Add blocking to increase curb height at any roof-mounted equipment where existing curb height does not meet minimum standards of the roof manufacturer. a) Attach a new 60-mil PVC roof membrane, using the induction welding method of attachment. (Note: all field welding shall be completed prior to the end of each day's application of membrane. Test welds shall be performed at membrane laps with test samples provided to the Owner, with the date and time of day for each test written on the sample. Test welds shall be performed no less than two (2) times per day - once before lunch and once after lunch, or in accordance with the manufacturer's recommendations.) h) Install new PVC-coated edge flashing and 24-gauge factory-coated clip-on fascia around perimeter of roof.

Raise curb at exhaust vents and other roof-mounted equipment as required by roof manufacturer. Reduce thickness of insulation around roof drains and overflow scuppers to facilitate drainage of the roof surface. e) Fully adhere 60-mil PVC to the cover board at the inside face of parapet walls, using solvent-based adhesive, and terminate at the underside of the concrete parapet cap (see Detail XX/XX). f) Fully adhere a new 60-mil PVC roof membrane to the cover board, using lowrise adhesive. g) Install all necessary terminations at perimeters, penetrations; roof drains flashings, curbs, etc., as required by the roofing manufacturer. Cover all exposed termination bars with new 24-gauge kynar-coated counterflashings and sealants at required locations. Kynar color to be selected by the Owner from the manufacturer's full range of standard colors. COMMUNITY CENTER (ROOF AREA "C" - APPROX. 520 SQ. FT.) o Steel bar joists o 3" Tectum deck (confirm thickness) o Modified bitumen roof membrane SCOPE OF THE WORK (ROOF AREA "C") - ROOF RECOVER: Recover the roof system on this small area of the roof. This work will include the following activities a) Remove and dispose of the 4" cant along the CMU wall adjacent to ROOF AREA "A". b) Remove the existing roof membrane from the areas identified as wet in Roof Asset Management's 01/11/23 Infrared Scan (EXHIBIT 1); inspect the Tectum deck for moisture and remove wet or otherwise unsuitable Tectum deck. Inspect for moisture damage beyond the limits shown on the Infrared Scan. Carefully document the total square footage of Tectum deck to be replaced in order to determine the final quantities required, for reconciliation of project costs upon completion of the project (see SECTION 01220: UNIT PRICES). c) Replace removed Tectum deck. Subject to a pull test (arranged for by the Contractor, with a report provided to the City and RAM), fully adhere new flat 1/2" polyisocyanurate cover board to the Tectum deck, using low-rise adhesive. d) Mechanically attach 1/2" cover board to the interior face of CMU wall adjacent to ROOF AREA "A", using drive pins and cover plates (see Detail XX/XX). e) Fully adhere 60-mil PVC to cover board at the inside face of parapet walls, using solvent-based adhesive. f) Pending a pull test (arranged for by the Contractor, with a report provided to the City and RAM), fully adhere new flat 1/2" polyisocyanurate cover board to the Tectum deck, using low-rise adhesive. g) Fully adhere a new 60-mil PVC roof membrane, using low-rise adhesive. h) Install new PVC-coated edge flashing and 24-gauge factory-coated clip-on fascia around perimeter of roof.

Fully adhere two layers of tapered polyiso insulation (3" combined minimum thickness, tapered at 1/8" per foot), using low-rise foam adhesive. (NOTE: the existing steel frame roof structure slopes at 1/8" per foot to the west and the north. The addition of tapered insulation at 1/8" per foot will increase the slope to 1/4" per foot, thereby improving drainage of the roof.) m) Subject to a pull test (arranged for by the Contractor, with a report provided to the City and to RAM), fully adhere new flat 1/2" polyisocyanurate cover board to the Tectum deck, using low-rise adhesive. n) Mechanically attach 1/2" cover board to the interior face of the CMU walls adjacent to ROOF AREAS "A", "B", and "C", (see Detail XX/XX). o) Fully adhere 60-mil PVC to the cover board at the inside face of parapet walls, using solvent-based adhesive. p) Subject to a pull test (arranged for by the Contractor, with a report provided to the City and RAM), fully adhere new flat 1/2" polyisocyanurate cover board to the polyiso deck, using low-rise foam adhesive. q) Fully adhere a new 60-mil PVC roof membrane, using low-rise foam adhesive. r) Install new PVC-coated edge flashing around perimeter of gymnasium roof (see ROOF EDGE DETAIL XX/XX). s) Install all necessary terminations at perimeters, penetrations; roof drains flashings, curbs, etc., as required by the roofing manufacturer.
