In such case, the Contractor shall not be entitled to receive any payment until the work is finished. If the unpaid balance of the Contract Sum exceeds the cost of finishing the work, includin€; compensation for the Engineer, additional services made necessary thereby, such excess shall be paid to the Contractor. If such costs exceed the unpaid balance, the Contractor shall pay the difference to the Owner. The amount to be paid to the Contractor or to the Owner, as the case may be, shall be certified by the Engineer, upon appl'.ication, and this obligation for payment shall survive the termination of the Contract.

Do not allow equipment to stand over, or store materials, on the freshly laid membrane. Asphalt dispensing equipment must have balloon tires. Delay any traffic over thc; freshly laid membrane system for a period of time; sufficient to allow the asphalt to set u.p. G. Apply asphalt so that a small bead of asphalt shows at the edge of the membrane:. Do not allow heavy flows of asphalt to extend beyond the membrane edge. Heavy, irregular surface flows of asphalt will make proper application of cap membrane difficult.. H. In the event a wrinkle or a "fishmouth" forms during the application of the membrane, do not "walk it down" as the memory of the sheet or felt may cause it to reappear. Fishmouths or wrinkles shall be sliced open and patched with hot asphalt and additional membranes. Avoid cutting into the plies below the fishmouth or wrinkle by angling the knife blade to the side. An equal number of plies shall be used to patch the number of cut out ply portions. 3.10 MEMBRANE APPLICATION A. DuraWeldTM 4M Modified Bitumen Membrane or an approved equal Do not install of DuraWeldTM APP torch grade membranes without careful review and implementation of all relevant safety and fire watch requirements including materials /combustible substrates. review, LP-Gas equipment storage anal Neches Engineers City of Port Arthur Project #08ti80 Page 34 handling guidelines, worker safety precautions and training. 2. Never apply DuraWeldTM APP membranes by any method except welding with a propane torch or other equipment specifically designed for application of APP modified bitumen. 3. Cap sheet application: Install full v~idth cap sheets, lapping 3" (7.6 cm) on the sides and 6" (15.2 cm) on ends. Stagger adjacent end laps a minimum of 18" (45.7 cm) apart. Offset cap sheet side and end laps from interply sheet side and end laps. 4. Turn the membrane up the wall or curb, above the cant, a minimum of 4"' (10.2 cm). This will allow for proper securement of the membrane prior to the base flashing installation. 5. All laps must be parallel or perpendicular to the slope of the roof such that the flow of water is never against the lap. 6. The coiled membrane must be unrolled approximately 10 ft. (3 meters), aligned, then the propane torch flame applied uniformly across the exposed back surface of the membrane and lap areas until the compound reaches the proper application temperature and exhibits a slight slheen. Be sure that there is complete burn-off of release films where present on the underside of the rolls, membrane selvage edges or both surfaces as applicable. Avoid overheating which may result in damage to or improper adhesion of the membrane. (The flame should be moved from side to side in the shape of an "L", applying about 75% of the heat to the membrane and 25% to the substrate or underlying plies including the lap area of the previously installed courses.) The membrane is slowly unrolled as heat is applied to ensure proper adhesion. When complete, re-roll the opposite end of the membrane and install in the same manner. 7. A minimum 3/g" (10 mm) asphalt flow-out must be obtained at all seam areas. Dry laps are not acceptable. To ensure the proper 3/g" (10 mm) flow of bitumen at the seam areas, a weighted roller may be used. Roller application should follow behind the torch no more than 4 ft. (1.2 m) nor less than 3 ft. (0.91 m) to be sure that the membrane will be at the proper temperature to produce proper flow. Hand rollers or "walking-in the seam" methods are also acceptable. Check all seams for full and uniform adhesion. Un-adhered seams must be lifted with a heate;d trowel and resealed by lightly torching the seam area. 8. Matching granules maybe broadcast into the modified bitumen bleed oust at seams while hot to enhance the finished appearance of the membrane. 9. All end laps must be staggered a minimum of 18" (45.7 cm) so that no adjacent end laps coincide. If end laps fall .~ line or are not staggered the proper distance, a full width of DuraWeldTM APP membrane must be installed over the end laps. 10. All laps must be parallel or perpendicular to the slope of the roof such water is never against the lap. 11. APP membranes must not be applied during adverse weather or without precautionary measures in temperatures below 45°F (7.2°C). Refer to Neches Engineers City of Port Arthur Project #08E~80 Page 35 manufacturer recommendations for additional information on Cold Weather Precautions. 3.11 MEMBRANE FLASHING A. Follow manufacturer's typical flashing procedures for all wall, curb, and penetration flashing including metal edging/coping and roof drain applications. B. Wall, curb and penetrator flashing shall be reinforced with an additional layer of DuraWeldTM 4M APP modified bitumen membrane or an approved equal. C. Basic wood blocking anchorage recommen<iationsare found in Factory Mutual Data Sheet 1- 49. These recommendations are required for Factory Mutual approved projects. D. All penetrations should be at least 18" (45.i' cm) from curbs, walls, and edges to provide for proper flashing. E. Install flashing sheets starting at low points. F. Where indicated by manufacturer's construction details, install base sheet or other modified bitumen pre-flashing in accordance with manufacturer's flashing requirements. G. Prime all metal and masonry with asphalt primer and allow to dry before being fully adhered to with flashing sheets. H. Only use U.S. Ply membranes or an approved equal in construction of flashing details. I. Do not use metal base flashing. J. Base flashing should extend a minimum of 8" (20.3 cm), and a maximum of 24" (61 cm) above the roofline. K. Corner membrane flashings, such as "bow ties" for outside corners and "footballs" for inside corners or other membrane reinforcements are required to ensure that base flashing corners are sealed at cant areas. Note: Mastic and fabric coursing is not an acceptable abternate for proper flashing and counterflashing details. L. Wood curbs and walls must be covered with a layer of Base Sheet or backer ply of selected two-ply flashing system and fastened 8" (20.3 cm) o.c. in all directions with approved fasteners with minimum 1" diameter or square caps. All vertical laps shall be 4" (10.2 crn). Base sheet or backer ply must extend out onto field of roof as shown in detail. M. Backer plies installed over masonry or other non-nailable substrates in cold adhesive or hot asphalt must be cut into manageable lengths to ensure adequate adhesion to carat strip and Neches Engineers City of Port Arthur Project #08680 Page 36 vertical surfaces without excessive voids. All vertical laps shall be. 4" (10.2 cm). Backer piy shall extend out onto field of roof as shov~nl in detail. N. Finish ply of selected base flashing detail must be run vertically to maintain selval;e edge at all vertical laps. O. All vertical laps shall be 4" (10.2 cm). Finish ply shall extend out onto field of roof as shown in detail, and must be extended a minimurn of 4" (10.2 cm) beyond edge of prior flashing plies. 3.13 METAL FLASHING A. Metal should not be used as a component of base flashing. Because of the high coefficient of expansion of sheet metals and the large temperature changes that can be experienced on a roof, sheet metal or exposed metal components must be isolated from the waterproofing components of the roofing and flashing system as efficiently a.s possible to prevent the metal from splitting the membranes. B. When it is unavoidable to use metal in the roofing system (i.e., lead flange at drains, gravel stops), treated wood nailers and insulation stops, 1" (0.5 mm) wider than the metal flange, should be provided for metal flange securement. C. Metal accessories (gravel stops, counter flashing, etc.) should be a minimum 16 oz. (0.56 mm) copper, 24 gauge (0.71 mm) galvani;~ed or stainless steel, 2 1/2 to 41b (l.l- 1.8 kg) lead, or 0.032" (0.81 mm) aluminum. D. Fabricate and install all sheet metal materials as shown in applicable construction in the Flashing Detail Section. Refer to SMACTfA (Sheet Metal and Air Conditioning Contractors National Association, Inc.) for guidance on sheet metal. treatments not addressed in this Manual. E. Clean metal and apply asphalt primer to all sheet metal surfaces that will come into contact with asphalt or other bituminous rnaterials; allow the primer adequate time to dry. F. Use fastener types compatible with the sheet metal type. Copper or lead-coated copper: use copper or- bronze fasteners. 2. Lead and galvanized steel: use galvanized or cadmium-plated sheet fasteners. 3. Aluminum: use aluminum fasteners. 4. Stainless steel: use stainless steel :fasteners. G. Metal counter-flashing shall have a minimum 4" (10.2 cm) face with a drip lip. The bottom edge of the counterflashing shall cover the roofing membrane and/or base flashing by a minimum of 4" (10.2 cm). Metal coi:mter-flashing used for masonry walls, wooden walls or through wall metal flashings should be two piece designs to allow for installation Neches Engineers City of Port Arthur Project #08Ei80 Page 37 and later removal. Metal counter-flashings for stucco, EIFS, wood siding or similar materials should be designed to receive arcd set as a base for those materials, such as "Z" type flashing, while providing for securement of separate metal counter-flashing to cover base flashings. Metal end joints shall be lapped 3" (7.6 cm) or more. Adequate fasteners must be provided to secure against effect of wind forces. Skirt fasteners shall be watertight. H. Metal termination bars shall be a minimwn of 1/10" (3 mm) thick x 1" (2.5 cm) wide with preformed sealant edge lap. Bar should have 1/4" (6 mm) x 3/g" (10 mm) slotted holes on 4" (10.2 cm) centers to facilitate mechanical anchorage. Note: Termination bars are not suitable in. all base flashing and wall flashing co~iditions. Termination bars may only be used in corjunction with an appropriate counter-flashing extending a minimum of 4" (10.2 cm) below the termination bar. L Metal flanges for gravel stops, eave strips and pitch pockets to be used in conjunction with roofing shall be primed (both sides). For APP roof systems set metal flangc;s in softened membranes (torch heated), and nail 4" (10.2 cm) o.c. to wood nailers or insulation stops. Flanges shall be a minirr~um of 3 1/2" (8.9 cm) wide for gravel stops or eave strips and 4" (10.2 cm) wide for projjections and extensions through the roof. The gravel stop or eave strip riser shall be at least 3/g" (10 mm) high for modified bitumen or smooth surface built-up roofing. Total height of riser should be adjusted to extend just above the finished surface, including gravel surfacing if present. Provision must. be made for securing the skirt to the face of the wall. This may be wood nailer strips for masonry and metal construction. In all cases, gravel stop and eave strip nailer should be fastened. to the deck or deck system with adequate resistance against wind forces. Stacks shall have metal sleeve flashing a minimum 8" (20.3 cm) high. Pitch pockets for brackets, supports, pad-eyes, etc., shall have a 4" (10.2 cm) minimum height metal sleeve. K. On reroofing projects, provisions shall be; made for reinstallation of existing sheet metal duct work, equipment, coping metal and counterflashings removed in conjunction with the new work. Also provide for cleaning and repairing of existing defective sheet metal., and replacement of missing and irreparable sheet metal to match existing types. L. Conduits and piping such as electrical and gas lines must be set on wood blocking or some other form of support. Wood blocking and supports must be set on doubler pads (an additional layer of the roof membrane). 3.14 DAILY SEAL A. If daily seals or water cutoffs are needed at the end of the day's work, they must be made of waterproof membrane and applied with hot asphalt or SBS flashing cement. Before restarting the job, all stops and cutoffs shall be cut out and completely removed. Neches Engineers City of Port Arthur Project #08580 Page 38 3.15 CLEAN UP A. Perform daily cleanup to collect all wrappings, empty containers, paper, and other debris from the project site. Upon completion, all debris must be disposed of in a legally acceptable manner. B. Prior to the manufacturer's inspection for warranty, the applicator must perform apre- inspection to review all work and to verify all flashing has been completed as well as the application of all caulking.
