All bidders must be prequalified Garland Roofing installers. The Owner reserves the right to reject any or all bids and to waive informalities, irregularities and/or errors in the bids to the extent permitted by law. This includes the right to extend the date and time for receipt of bids. a. On all indicated tear-off sections, complete a full tear-off of, but not limited to, edge metal details, field and flashing membrane, all layers of insulation, and vapor barrier (if present) down to decking. Properly dispose of debris. b. On all indicated recover sections, remove but not limited to, edge metal details, flashing membrane, wet insulation as indicated on report or found during construction, membrane and insulation around drains where new sumps will be installed, and loose surface granules. Properly dispose of debris. c. Remove all abandoned curbs and penetrations down to decking. Properly fill voids/openings below decking with insulation and install new decking of like and kind, or cover small openings with thick steel plating. Secure perimeter of steel plating to assure proper alignment and securement is achieved. d. Raise all roof penetrations as necessary so to allow flashing heights of a minimum 8" height and install proper curb or rail details (lumber on top of roof is not acceptable). All costs associated with the proper raising of penetrations are the responsibility of the roofing contractor. Utilities such as, but not limited to gas lines, electrical wires, conduit, duct work, disconnect boxes, etc. must be properly disconnected and supported by a qualified contractor prior to the units being elevated. All equipment and utilities are to be properly revised to accommodate the new curb height. The roofing contractor is responsible for the coordination and scheduling of services. All interruptions of utility usage must be pre-approved by and coordinated with hospital officials. e. On areas of full tear-off over wood and gypsum decking, install a nailable base sheet over prepped and cleaned decking. Pull testing and test results, by fastener manufacturer, require submittal prior to the pre- onstruction meeting. Test results will determine proper fastener type and fastener pattern requirements. f. On areas of full tear-off over sloped decking, install two layers of properly staggered 2.0" insulation board. Mechanically attach or adhere per deck type, deck exposure conditions and per KEE-Hybrid specification requirements and per patterns required by Wind Uplift Pressure calc. See provided fastener and adhesive ribbon pattern drawings. g. On areas of full tear-off over flat decking, install one layer of 2.0" insulation board and a secondary layer(s) of a fully tapered insulation system. Mechanically attach or adhere per deck type, deck exposure conditions and per KEE-Hybrid specification requirements and per patterns required by Wind Uplift Pressure calc. See provided fastener and adhesive ribbon pattern drawings. NOTE: On the elementary roof section #14, taper layout is to account for and eliminate ponding water, caused by deflection in decking, along both drip edges. h. On areas of recover, properly clean, prepare and prime the surface of the existing membrane. Complete adhesion test prior to installation. i. On areas of recover, install and adhere 1.0" insulation board in low rise foam adhesive per KEE-Hybrid specification requirements and per patterns required by Wind Uplift Pressure calc. See provided ribbon pattern drawings. j. Install tapered insulation sumps around all drain locations on both tear-off and recover roof areas. Sumps are to be a minimum of 1/2:12 slope and 8' x 8' in size. k. On both tear-off and recover areas, install minimum 1/2:12 tapered polyiso saddles/crickets in all areas necessary provide proper and adequate slope and drainage, including, but not limited to, between drains, in outside corners, between drains and perimeter walls, and on the high side of penetrations/curbs. Increased taper may be required on roof sections with increased slope. Saddle/cricket widths are to be 1/2 of that of their length. Roof systems resulting in areas of ponding water is not acceptable and will require the contractor to correct at their expense. l. Adhere cant strip at all vertical to horizontal transition points along, but not limited to, penetrations, curbs, walls, area dividers/expansion joints, and roof height transitions. m. Install one layer of 1/2 " Densdeck Prime recovery board in low rise insulation adhesive per patterns required by Wind Uplift Pressure calc. n. Install a base layer of Garland's high performance SBS base sheet in Green-lock interply cold process adhesive, or by torch applied method. Secure each layer of the membrane by using a 50-lb. roller 30 minutes after on cold process, and immediately after torch application. o. For cold process methods, cut the base sheets in 1/3rds and cap sheets in half and let them relax before installation for a minimum of 1 hr. If the membrane is installed at night, or at low temperatures, it can blister during the day when the temperatures get high. Installation during cold temperatures requires consistent utilization of, and storage of all rolls in hot boxes that are capable of achieving and maintaining proper installation temperature. Hot box must have a watertight enclosure. Keep bleed-out to a 1/4" and use the weighted roller to get air pockets out from under the sheet. Priming of the base sheet top surface may be required prior to the installation of the cap sheet in cases the surface of the base sheet becomes dirty. p. Install Garland's high-performance fleece back KEE membrane in low rise foam adhesive per manufacturer's installation requirements. Low rise foam adhesive is to be applied by way of spatter spray method. Please reference manufacturer's detailed KEE hybrid system application guidelines. Clean, unsoiled footwear and/or protection is required when walking on the KEE membrane during and after installation. Soiled and stained membrane will not be accepted and may require replacement. q. Install all new raised edge perimeter, penetration, and projection flashings using a base ply of Garland SBS modified base sheet. Set the SBS base sheets in cold process Green-Lock Flashing adhesive, or torch application. r. Install KEE-Stone Non-fleece back flashing membrane over the new SBS base sheet flashing. KEE-Stone NF Flashing membrane is to be adhered by way of Garland KEE Flashing Adhesive . Leave the bottom 3" free of adhesive to allow for heat-welding of cap flashing membrane to field membrane. s. All modified base flashings should be sealed at the end of each day, no exceptions. Apply Green-Lock SA to top of termination bar and along the toe edge. Any flashing that is terminated prior to passing over the top edge of the perimeter wall or penetration is to receive a termination bar, greenlock structural adhesive and counter-flashing detail per provided detail drawing. Termination bar and caulking should be installed daily. All flashing ply is to be sealed on a daily basis with roofing cement and mesh after being secured. All block wall flashing is to be terminated and counterflashed under new through wall metal as specified on provided detail drawing. t. Install new 22-gauge, metal details at all, but not limited to, gutters, parapet walls, drip edges, raised metal edges, expansion joints, area dividers, under window sills, roof transitions, counterflashing, etc. The raised edge metal detail will consist of an aluminum extruded cleat and snap-on architectural metal and must meet the ANSI/SPRI ES-1 code requirements. u. Install rubber roof mats at the base of all roof access doorways, attached ladders , at HVAC unit access doors, and stairways. v. Paint all existing steel gas lines safety yellow, or a color of client's choice. w. Replace drain strainer covers with new aluminum units. Replacement units must be of the proper type and size for existing drain bowl/ring.
