Clarion Roofing A Quorum was established. Chairman Cloudy turned the meeting over to Alan Verbitsky to share the Concept Analysis of the Kodiak Island School Re-Roof project created by Jensen Yorba and Lou. Inc. Alan Verbitsky, Director of Engineering & Facilities Dept, Kodiak Island Borough thoroughly presented the report submitted by Jensen Yorba and Lott, Ine.(see attached original copy of Concepts Analysis). The report offered a comparative analysis of various roof replacement options for three buildings on the Kodiak High School Campus; the Shipping & Receiving Building, the Classroom 13uilding, and the Vocational Education Building. Mr. Verbitsky shared extensively the many rooting systems considered: Traditional three or Live ply built up roof: Cap Sheet; APP Modified. Bitumen; SBS Modified Bitumen; Resin Roofing; Ballasted Inverted Roof Assembly (IRMA); 13PDM, aMechanical Fastening; EPDM, Fully Adhered; Low Slope Metal Rooting; Standard slope root Polyisocianurate insulation Expanded Polystyrene Insulation C.vtrudcd Polystyrene Insulation; Mr. Verbitsky opened the discussion oldie existing building conditions to the members of the Architectural Review Board. Upon several hours of general discussion among the Architectural Review Board it was a consensus there were three options available for Kodiak Island. The three options available are as follows: I. Option I - PVC (fully adhered) Membrane: The bare steel deck will be overlayed with a non-structural protection board that creates a flat surface for the installation of a vapor barrier (10 mil PVC). Rigid insulation (ESP or Polyiso) is loose laid on top of the vapor barrier, A structural 7/I6"thick Al'A rated oriented strand board will be mechanically fastened to the steel deck with 16 or more screw fasteners per panel. 2. Option I I - PVC (Mechanically Fastened) Membrane: The bare steel deck will be overlayed with a non-structural protection board that creates a fiat surface for the installation of a vapor barrier (10 mil PVC). Rigid insulation (EE'S or Polviso) is loose laid on top of the vapor harrier. A non structural underlaymenl panel (I/4" reinforced gypsum board "Dens- Dec') will be mechanically fastened to the steel deck with 3 screw fasteners per panel. 3. Option III - Sloping Rool1 Structural wood trusses at 24" on center span from outside wall to outside wall. They would be connected to the z existing concrete block walls through the existing roofing. The trusses would support a 3/8" thick plywood deck over which a 30 pound felt underlayment would he installed. Ice and water shield would be installed around the eaves and rakes. A standing seam metal roof similar to GRP "Zip Rib" would be installed on slip clips that eliminate through fasteners. The roof panels would be installed in a conventional 3:12 pitch, with continuous metal panels. All roof penetrations must be carefully detailed to allow for expansion of the roof panels. Integral gutters will be provided only where required to protect doorways and the areas below eaves. The existing roof would remain in place and be repaired so that it functions as a vapor harrier. Fiberglass insulation would be installed over it to achieve the R value required. The attic space would not have to be sprinklered, but draft stops would have to be installed at every 3000 sf. J Rooftop mounted mechanical equipment would be rerouted to anew exhaust fans and exhausted out the gable ends through hooded louvers. New boiler flues would penetrate the roof assembly. The attic must be ventilated. After extensive discussion of the three options, it was decided by the Architectural Review Board that all three projects will have the same roof. Director Verbitsky also advised that whoever received the bid on the re-roof project needed to be in place and ready to work the day school ends for summer break. The time frame for completion of the project is the scheduled summer break. Upon closure of the discussion of options, it was unanimously decided by the Architectural Review Board to go with Option 2, PVC (Mechanically fastened) membrane for the entire re-roof project. IV.
