The Contract Sum and the Contract Time may be changed only by Change Order. A Change Order signed by the Contractor indicating his agreement therewith, including the adjustment in the Contract Sum or the Contract Time. Neches Engineers City of Port Arthur Project g06340 Page 14 10. Changes in the Work (Continued) The Owner, without invalidating the Contract, may order changes in the work within the general scope of the Contract consisting of additions, deletions or other revisions, the Contract Sum, and the Contract Time being adjusted accordingly. All such changes in the work shall be authorized by Change Order, and shall be performed under the applicable conditions of the Contract Documents. The cost or credit to the Owner resulting from a change in the work shall be determined in one or more of the following ways: a. by mutual acceptance ora lump sum properly itemized and supported by sufficient substantiating data to permit evaluation; b. by unit prices stated in the Contract Documents or subsequently agreed upon; c. by cost to be determined in a manner agreed upon by the parties and a mutually acceptable fixed or percentage fee. If the Contractor wishes to make a claim for an increase in the Contract Sum, he shall give the Engineer written notice immediately after the occurrence of the event, giving rise to such claim. This notice shall be given by the Contractor. The Engineer will have authority to order minor changes in the work not involving an adjustment in the Contract Sum or an extension of the Contract Time and not inconsistent with the intent of the Contract Documents. Such changes shall be effected by written order, and shall be binding on the Owner and the Contractor. The Contractor shall carry out such written orders promptly. 11. Uncovering and Correction of Work If any portion of the work should be covered contrary to the request of the Engineer or to requirements specifically expressed in the Contract Documents, it must, if required in writing by the Engineer, be uncovered for his observation and shall be replaced at the Contractor's expense. If any other portion of the work has been covered which the Engineer has not specifically requested to observe prior to being covered, the Engineer may request to see such work and it shall be uncovered by the Contractor. If such work be found not in accordance with the Contract Documents, the Contractor shall pay such costs unless it be found that this condition was caused by the Owner or a separate contractor, in which event the Owner shall be responsible for the payment of such costs. If Contractor shall promptly correct all work rejected by the Engineer as defective or as failing to conform to the Contract Documents whether observed before or after completion and whether or not installed or completed. The Contractor shall bear all costs of correcting such rejected work, including compensation for the Engineer's additional services made necessary thereby.

Uncovering and Correction of Work (Continued) If, within two years after the Date of Completion of the work, any of the work is found to be defective or not in accordance with the Contract Documents, the Contractor shall correct it promptly after receipt of a written notice from the Owner to do so unless the Owner has previously given the Contractor a written acceptance of such condition. This obligation shall survive termination of the Contract. The Owner shall give such notice promptly after discovery of the condition. The Contractor shall remove from the site all portions of the work which are defective or non- conforming unless removal is waived by the Owner. If the Owner prefers to accept defective or non-conforming work, he may do so instead of requiting its removal and correction: in which case, a Change Order will be issued to reflect a reduction in the Contract Sum where appropriate and equitable. Such adjustment shall be effected whether or not final payment has been made. 12. Termination of the Contract If the work is stopped for a period of thirty (30) days under an order of any court or other public authority having jurisdiction, or as a result of an act of government, such as a declaration of a national emergency making materials unavailable, through no act or fault of the Contractor or a Subcontractor or their agents or employees or any other persons performing any of the work under a contract with the Contractor, then the Contractor may, upon seven additional days' written notice to the Owner and the Engineer, terminate the Contract and recover from the Owner payment for all work executed and for any proven loss sustained upon any materials, equipment, tools, construction equipment and machinery, including reasonable profit and damages. If the Contractor is adjudged a bankrupt, or if he makes a general assignment for the benefit of his creditors, or ifa receiver is appointed on account of his insolvency or if he persistently or repeatedly refuses or fails, except in cases for which extension of time is provided, to supply enough properly skilled workmen or proper materials, or if materials or labor, or persistently disregards laws, ordinances, rules, regulations or offers of any public authority having jurisdiction, or otherwise is guilty or a substantial violation of a provision of the Contract Documents, then the cause exists to justify such action, may, without prejudice to any tight or remedy and after giving the Contractor and his surety, if any, seven days written notice, terminate the employment of the Contractor and take possession of the site and of all materials, equipment, tools, construction equipment and machinery thereon owned by the Contractor and may finish the work by whatever method he may deem expedient. 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, including 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 application, and this obligation for payment shall survive the termination of the Contract.

After allowing the base sheet to relax, keep sheet taut, fastening at center of sheet and working in opposite directions. Push all wrinkles and buckles ahead as fastening proceeds. The following are minimum fastening patterns that may be used when fastening the base ply. For FMRC approved fastening patterns, refer to the current FMRC Approval Guide. 1. Base sheet (no insulation) on decks of wood, plywood, OSB, lightweight concrete, gypsum, or cementitious wood fiber: Lap the base sheet 2" (5 cm), and mechanically fasten with three rows of fasteners. The first row (on the seam) will be 1" (2.5 cm) from the leading edge and on 9" (22.9 cm) centers. Locate the second row of fasteners 12" (30.5 cm) from the leading edge and on 18" (45.7 cm) centers. The third row of fasteners shall be 24" (61 cm) from the leading edge on 18" (45.7 em) centers. The centers for the second and third rows should be staggered. 3.04 INSULATION INSTALLATION A. General 1. Application of roof insulation shall not commence until all other trades have completed work that require them to transverse on the deck on foot or with equipment. 2. Install insulation boards per insulation board manufacturer's requirements. 3. Do not install wet, damaged or warped insulation boards.

Use only an ASTM D312, Type III or Type IV Steep Asphalt. Type III asphalt can be used on slopes up to ½" per foot ( 4 cm per meter). Type 1V asphalt must be used on all slopes greater than ½" per foot ( 4 cm per meter). Neches Engineers City of Port Arthur Project #06340 Page 33 C. Discontinue application of asphalt over any substrate where foaming of asphalt is observed. D. Application with hot aphalt requires continuous, uniform interply mopping rates of 25 lbs +/- 20% per 100 square feet of roof area (1.2 kg/m2). To little asphalt may result in voids. Too much asphalt can cause membrane slippage. E. When applying fiberglass base or ply sheets, the point of application temperature of the asphalt must be at the Equiviscous Temperature (EVT) with a tolerance of+/- 25°F (13.9°C), at which a viscosity of 125 centipose is attained. When using mechanical asphalt applicators, the target viscosity should be 75 centipose. F. For all SBS modified membranes; the minimum point of asphalt application temperature must be at the EVT or 425°F (218°C), whichever is greater, with a rolling bank (puddle) of mopping asphalt across the full width of the roll. G. Refer to the asphalt carton labels or bills of lading for the equiviscous temperature (EVT) for the asphalt. H. For substrates that absorb asphalt, apply asphalt in sufficient quantity to assure the level of adhesion specified. I. Asphalt application shall not commence when the outside temperatures are below 45°F (7.2°C) unless cold weather application instructions such as using insulated piping and luggers to maintain the required asphalt temperature at the pint of application and using products stored above 55°F (12.6°C) for at least 24 hours prior to installation. J. The operator of the roofing bitumen kettle shall be fully trained and familiar with its safe operation and have the required safety equipment and clothing for his protection. K.

Do not heat the asphalt to or above the flash point. N. Do not hold the asphalt at temperatures above the finished blowing temperature for more than 4 hours. O. Do not keep heated tankers above 325°F (163°C) ovemight or on weekends if not in use. P. The roofing bitumen kettle shall be placed a safe distance from the building up on plywood or a tarp to facilitate easy clean up. 3.06 CANT STRIPS Neches Engineers City of Port Arthur Project g06340 Page 34 A. Cant strips must be installed on top of the roof insulation or wood nailers and at the intersections of the roof and all walls, parapets, curbs, or transitions that are approximately 90 degrees, where area is to be flashed. B. Cant strips shall be approximately 4" (10.2 cm) in horizontal and 4" (10.2 cm) in vertical dimensions. The face of the cant shall have an incline of not more than 45 degrees with the roof. C. Mechanically fasten where applicable. Otherwise, set in hot asphalt or USPTM #643 Flashing Cement or an approved equal. D. Miter and neatly fit all joints. 3.07 EDGE STRIPS A. Edge strips must be installed on top of the roof insulation or wood nailers at the intersections of roof and perimeter or drain openings where it is required to provide a smooth transition from horizontal to vertical surfaces or for transitions from lower to higher elevations. B. Edge stips may be mechanically fastened or set in hot asphalt depending on the phase and method of installation. C. Miter and neatly fit all joints. 3.08 WOOD NAILERS A. Wood nailers must be 3-1/2" (8.9 em) minimum width or 1" (25 cm) wider than metal flange and minimum 1" (25 cm) thick and securely fastened to the deck. B. Wood nailers must be pressure treated and have water based preservatives. Petroleum or creosote base preservatives are not recommended because of possible incompatibility with asphalt-based products. C. Wood nailers are required at all roof to wall transitions of parapets, eaves, gable ends, penetrations or wherever metal flanges must be incorporated into the roof system. D. Nailers must be fastened to the deck. E. Wood nailers shall match total insulation thickness. F. Slotted wood nailers must be used where perimeter venting is required. 3.09 INTERPLY SHEET APPLICATION Neches Engineers City of Port Arthur Project #06340 Page 35 A. Three ply interply applications: Install starter strips of 12" (30.5 cm), 24" (61 cm) and 36" (91.4 cm) widths and follow with a second full 36" (91.4 cm) width sheet with a maximum 11-1/3" (28.8 cm) exposure, applied shingle style. Lap sheets 24-2/3" (62.7 em) with an 11-1/3" (28.8 em) exposure and lap 4" (10 em) at ends. Stagger adjacent end laps a minimum of 12" (30.5 em). Install the felts in full and uniform mopping of hot asphalt applied at the rate of 25 lb/square (1.2 kg/m2) 4- 20%. B. Turn plies up to the top of the cant. C. Valleys and waterways shall receive an extra layer which shall be a full width wide and shall extend at least 8" (20.3 cm) up the inclines out of the valleys, set in a uniform mopping of hot asphalt, optimium of 25 lb/square (1.2 kg/m2) 4- 20%. D. Foot and machine traffic on freshly applied membranes with asphalt must be kept to a minimum to reduce the possibility of asphalt displacement due to "point applied" pressure. The potential result is the creation of an area where the asphalt quantity may be too light to perform the required waterproofing function. E. Workmen must stand on the insulation or deck side of the system and avoid traffic on the freshly laid membrane system for a long enough time to allow the asphalt to set up. F. 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 the freshly laid membrane system for a period of time sufficient to allow the asphalt to set up. 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 1. 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 and handling guidelines, worker safety precautions and training. 2. Never apply DuraWeldTM APP membranes by any method except welding with a Neches Engiaeers City of Port Arthur Project #06340 Page 36 propane torch or other equipment specifically designed for application of APP modified bitumen. 3. Cap sheet application: Install full width cap sheets, lapping 3" (7.6 em) on the sides and 6" 05.2 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 pr/or 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 sheen. Be sure that there is complete bum-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 3/8" (10 mm) asphalt flow-out must be obtained at all seam areas. Dry laps are not acceptable. To ensure the proper 3/8" (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 heated trowel and resealed by lightly torching the seam area. 8. Matching granules may be broadcast into the modified bitumen bleed out 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 in 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 manufacturer recommendations for additional information on Cold Weather Precautions. Neches Engineers City of Port Arthur Project #06340 Page 37 3.11 MEMBRANE FLASHING A.

Note: Termination bars are not suitable in all base flashing and wall flashing conditions. Termination bars may only be used in conjunction with an appropriate counter-flashing extending a minimum of 4" (10.2 cm) below the termination bar. I. Metal flanges for gravel stops, cave strips and pitch pockets to be used in conjunction with roofing shall be primed (both sides). For APP roof systems set metal flanges in softened membranes (torah heated), and nail 4" (10.2 cm) o.c. to wood nailers or insulation stops. Flanges shall be a minimum of 3 1/2" (8.9 cm) wide for gravel stops or cave strips and 4" (10.2 cm) wide for projections and extensions through the roof. The gravel stop or cave strip riser shall be at least 3/8" (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 cave strip nailer should be fastened to the deck or deck system with adequate resistance against wind fomes. J. 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.
