Itis anticipated thatmaterial transport to the roofarea will be performed from N Bayou St. Bid accordingly for overhead safety. Remove all transportable Mobile County property from below the work area to prevent damage. Employee/pedestrian access should be rerouted or provide a temporary safety enclosure if directly below or toward the perimeter of work area(s). The replacement roofsystem shall be from Johns Manville or a comparable roofing manufacturer. All relevant roofing components shall be provided from the same manufacturer and approved by said manufacturer Install poly-isocyanurate per manufacturer recommendations. Per the Alabama Building Code, Addition a minimum R-value of R-25 is required (approx. 4.5" of polyiso insulation). Ensure insulation joints (horizontal and vertical) are properly staggered a minimum of 6" to prevent thermal bridging. Design drainage/taper system to ensure positive drainage with no standing water occurrence within a 48-hour period following a rain event. Cricket length to width ratio should not exceed 3:1. Adjust flashing heights as needed to ensure 8" minimum flashing heights throughout the roof area Install fiberglass faced gypsum substrate boards per manufacturer recommendations. Ensure board joints are staggered a minimum of 6". Any boards cracked or broken during the installation process should be removed and replaced. Roof insulation and cover board should be attached to the lumber deck via mechanical fasteners. The roof assembly number and fastener spacing patterns should be provided by the roofing manufacturer to meet required wind loads. Ensure fastener shanks accommodate for additional insulation heights where insulation crickets are present. . Install new 60 mil PVC membrane per manufacturer installation recommendations. Ensure proper membrane lapping so that water flows over membrane laps rather than into them. Ensure a minimum 1 J4" wide heat weld at laps. Install pressure treated lumber nailers if/where applicable to repair/replace any damaged lumber. Nailers should be at proper height to accommodate J4" per 12" taper design. Utilize 316 stainless steel fasteners for nailer attachment. Install a self-adhered bond break between pressure treated wood if required by the manufacturer. High copper volume in the pressure treated wood could cause galvanic action (corrosion). Include unit price for lumber in bid to accommodate any unforeseen need for additional lumber. Install new Galvalume coping cleat along all parapet perimeters. A Kynar coated aluminum coping cap should then be installed/fastened atop the cleat. Ensure the new roof membrane saddles the parapet wall prior to coping cleat cap installation. Ensure proper overlap and commercial grade low modulus sealant application at coping cap joints. Apply commercial grade low modulussealant at all coping fastener penetrations Remove and replace all roof to masonry wall flashing with new 316 stainless steel counter-flashing.

Ensure flashing heights are a minimum of 8" above the roof plane The four (4) verified drain conditions appeared to be corroded but in working order. Bid to install retrofit drains at all verified existing drain locations within the roof area.
