GA Apron & Parking Lot Rehabilitation Project Contract No. CAG-25-013 Page 2 of 2 THE CONTRACT IS MODIFIED AS FOLLOWS: Description of Change: Adding Change Order Proposal 4. Reason for Change: (COP 4) The plans and specification failed to account for a 50+ year old and brittle storm drainage pipe under the pavement at the Windsock apron. In following the specifications for compaction of the new rock and asphalt the existing storm drainage pipe experience failure in several places. This COP 4 covers the removal of approximately 154’ of the damaged storm drainage pipe with like material and shape as the existing system. The replacement will also add a layer of Controlled Density Fill (low strength concrete) to protect the pipe from damage in the future. COP 4 = $45,000+ Sales Tax (10.3%) = $45,000+ $4,635= $49,635.00 Materials: See the attached price breakdown for the lump sum labor, equipment and materials. Plans: N/A Equitable Adjustment: N/A Extension of Time: The Time for Completion is extended 4 Working Days. Sections 1-04.4 and 1-04.5 of the 2018 WSDOT/APWA Standard Specifications shall govern this Change Order. The Work of the referenced Contract is modified to include the changes detailed herein. The payment provided for herein shall constitute the complete and final settlement for all costs of labor, equipment, materials, overhead, profit, permit fees, and all other claims that may be made by the Contractor as a result of this change.

In addition, this significant AMERICAN development, a dependable, single gasket, push-on type joint meeting the requirements of AWWA C111, affords the customer lower joint cost and time-saving advantages in installation. It pro- vides exceptional strength and flexibility and has been widely accepted by engineers, con- tractors and utility officials since the 1950s. For added flexibility during construction, and for possible elimination of bends, a liberal 5° allowable deflection is standard in all sizes through 30”, offering 21” offset in a 20’ length of pipe. Liberal deflection can also be provided in larger diameter pipe with standard and Special Fastite Deflection Bells. The patented AMERICAN Fastite Joint embodies many advanced design features and is rated for a water working pressure of 350 psi. For specific conditions, ductile iron piping with this joint has been approved for much higher pressure conditions. The socket, which is scien- tifically designed with two gasket recesses and a dividing buttress, is manufactured to close toler- ances so that the gasket is self-centered, securely confined, and firmly compressed for a perma- nent, tight, trouble-free joint. The Fastite joint seal, bubble-tight under vacuum and external pressure, becomes even tighter with the appli- cation of internal pressure due to a specially designed wedging surface in the socket. Fastite Joint Assembly The bell opening is slightly tapered to provide easy entry of the pipe end; the flared socket design permits liberal joint deflection. The plain end of the pipe is tapered or rounded to facilitate entry into the bell and self-centering in the gasket. On pipe cut in the field, the plain end can be easily beveled and smoothed by the use of a portable grinding wheel or other suitable apparatus. Methods of cutting ductile iron pipe are described in Section 3. A stripe is painted on the plain end of AMERICAN Fastite Joint Pipe to provide a visual means of checking the joint alignment and to assure proper insertion. See page 2-10 for detailed assembly instructions. Fastite Gasket The Fastite Joint sealing component—a molded synthetic rubber ring gasket of two hardnesses, shaped to fit the configuration of the gasket socket—is manufactured per all requirements of ANSI/AWWA C111/A21.11 and under AMERICAN’s own rigid specifica- tions, assuring closely controlled dimensional and hardness properties. The smaller end of the gasket is of harder rubber, approximately 85 durometer hardness, which provides a strong shoulder for self-centering on the gas- ket buttress, a permanent seal against cold flow, and protection from deterioration. The larger end of the gasket is of softer rubber, approximately 65 durometer hardness, provid- ing ease of assembly and positive sealing. The design assures effective sealing at low or high pressures and in straight or deflected joint alignment. It also eliminates any concerns of infiltration or root intrusion, and assures posi- tive sealing against negative pressure, thus preventing gasket “pullout” should a vacuum be created in the line. A taper on the inside of the gasket allows the entering pipe to locate and center on the hard section and reduces friction loads during AMERICAN Fastite®Joint Pipe For Water, Sewage or Other Liquids 20-2 Storm Pipe - 8" D.I.

The snug fit and the hard section of the gasket, in conjunction with the design of the buttress, act to restrain the gasket against dislodgment during assembly. Additional internal pressure results in increased tightness of the seal when pipe is either in straight alignment or deflected. Gaskets made of SBR (Styrene Butadiene Rubber) are standard. For information on gas- kets made of special types of rubber, for applications involving air or liquid tempera- tures in excess of 150°F, or for chemical, hydrocarbon or other special service applica- tions, and for installations in contaminated soils where permeation through gaskets might be a concern, consult AMERICAN for recom- mendations. See Table 2-1. Fastite Lubricant AMERICAN Fastite Joint Lubricant is a non-toxic water soluble material imparting nei- ther taste nor odor to the conveyed water and is ANSI/NSF 61 approved. The lubricant is suitable for use in hot or cold weather and will adhere to wet or dry pipe. AMERICAN Fastite Joint Pipe can be assembled when submerged, though for such installation, special AMERICAN underwater joint lubricant is recommended. See Table No. 2-5 for appropriate lubricant quantities. Fastite Joint Materials Standard joint materials include Fastite plain rubber gaskets and a sufficient supply of Fastite joint lubricant. Fastite pipes are most often readily joined with available excavating equipment; however, assembly tools can be supplied by AMERICAN on a loan basis with a nominal deposit which is refundable upon return of tools in good condition. Fittings AMERICAN Fastite or Flex-Ring fittings and AMERICAN Mechanical Joint Fittings are used with Fastite Joint pipe. See Sections 4 and 5. Coating and Lining AMERICAN Fastite Joint Pipe can be fur- nished asphaltic coated, cement lined, or with special coating or lining where required. See Section 11.

The ANSI/AWWA C600 Standard covers in detail the installation of ductile iron water mains, including assembly instructions for push-on joint pipe. Field-cutting of AMERICAN Ductile Iron Pipe can be easily performed, thus eliminat- ing the necessity for factory-made special lengths of Fastite pipe. The plain end of Fastite pipe cut in the field requires little or no preparation for assembly into the socket of a mechanical joint fitting. Where a cut pipe is to be assembled into a Fastite socket, the required beveling or rounding of the plain end can be easily accomplished by the use of a portable grinding wheel or other suitable apparatus. Methods of cutting duc- tile iron pipe are described in Section 3. The AMERICAN Fastite Joint requires only one joint component, the rubber gas- ket*, which when properly installed, fits snug- ly in the gasket recess in the bell socket. A special lubricant supplied with the pipe is applied to the plain end and the inside surface of the gasket before assembly. The pipe end is tapered or rounded to provide self-centering of the plain end in the gasket and ease of assembly. A circumferential stripe on the plain end provides a visual indication for checking the proper insertion of the joint. The stripe, shown in the photographs illustrating assem- bly methods, passes fully into the bell when the plain end is fully inserted into the socket with the two lengths of pipe in straight alignment. Joints can then be safely deflected up to the extent shown in Table No. 2-3. In deflected joints, the stripe will typically be visi- ble to some extent after assembly. Easier assembly is effected if the pipe is suspended an inch or so off the bottom of the trench during the jointing operation. The following instructions should be fol- lowed in order to properly assemble the joints and to fully realize the maximum speed and ease of assembly of the Fastite Joint: 1. Clean socket and plain end thoroughly, removing mud, gravel, or any other matter that might cause the front of the gasket to protrude into the path of the entering spigot. 2. Insert gasket fully into the gasket recess of the socket, large end of the gasket entering first. Gasket may be installed with one or two V-shaped folds as shown (Photo 1). After the gasket is in place at the bottom, the top of the gasket is positioned fully into the gasket recess. Gaskets and lubricant to be installed in very cold weather should be warmed first (as by storage in a heated equipment cab or pick-up, etc.) for optimum assembly. 3. Apply a thin film of regular AMERI- CAN Fastite Joint Lubricant to the rounded or tapered spigot end of the pipe, the immedi- ate outside pipe surface between the stripe and the nose of the pipe (Photo 2), and also to the inside surface of the gasket. Special AMERICAN Fastite Joint Lubricant intended specifically for underwater or very wet instal- lations can be supplied when requested. AMERICAN Fastite®Joint Pipe Assembly Instructions Photo 1 Photo 2 *Gaskets not used immediately should be stored in a cool location, out of direct sunlight. "!# 2-11 Caution:If a spigot end contacts the ground or trench side after lubrication, any adhering dirt or rocks should be cleaned off and the area re-lubricated prior to assembly. 4. Insert the plain end in the socket. For optimum assembly it is preferable that the entering pipe be in reasonably straight align- ment; however, the Fastite Joint may be assembled if necessary with the pipe deflect- ed within its rated deflection. (Exception: If Fast-Grip gaskets are being used, straight alignment must be maintained.) Push the plain end into the socket using any of the applicable assembly methods described hereinafter. If the joint cannot be assembled with a moderate force, remove the pipe and check for the cause of the difficulty, such as improper positioning of gasket, insufficient or wrong type lubricant, dirt under or behind the gasket, dirt adhering to the pipe, or any other cause which would result in obstruc- tion or increased friction between pipe end and gasket surface. For assurance of proper assembly, a thin automotive, blade-type feeler gauge can also be used if desired for quick and easy probe confirmation of cor- rectly installed axial gasket position around the joint. 5. “Backwards” installation. AMERICAN does not recommend “backward laying” (bells assembled over spigots, rather than spigots inserted into bells as pictured in this literature) of large-diameter ductile iron pipe in buried installations. AMERICAN can furnish bell and plain end fittings to minimize the need for backward pipe laying. Other devices such as sleeves and couplings may also be employed for this reason. However, if this condition cannot be avoided, we strongly recommend that installers contact AMERICAN for instructions on how to reduce the potential for problems that could occur when assembling pipe in this manner. In general, Fastite joints or other Fastite gasketed pipes may be readily pushed or pulled together without the need for com- plicated tools or substantial manpower. This is most often accomplished with the proce- dures discussed on page 2-14. In general, the joints of AMERICAN push-on pipes are purposefully “tight,” and most joints require an assembly force of about 100 to 200 pounds or more of assembly force per inch of pipe diameter (i.e. a 12" joint might require about 12 x 100 or 1,200 pounds of assembly force). In pulling operations, simply wrap a sound wire rope choker cable or nylon sling around the barrel of the entering pipe. Secure the thimble eye or other end loop of the choker to a suitably anchored pulling device (e.g. backhoe, come-along, etc.). Use the mechanism to pull the cable taut in the assembly direction (Photo 3). Continue pulling the cable in a smooth, continuous motion until the joint is in the fully assembled position. If desired for special conditions, AMERICAN can furnish suitable, simple come-alongs and choker cables for man- Photo 3 AMERICAN Pipe Assembly Mechanisms "!# 2-12 power assembly of most 4"-24"pipes (See Figure 1 and specify pipe sizes involved). The joints may normally be disassem- bled in a similar manner, reversing the direction of the pull with the choker cable (Photo 4). It is also sometimes helpful to use rebating or wiggling deflection to aid in the disassembly of push-on joint pipes, par- ticularly when pipes have been installed for some time prior to removal. 30"-64" Pipe Large pipes are most often readily pushed or pulled together with heavy exca- vating/earthmoving equipment available on- site (see page 2-14). In cases where assembly of pipes by manpower is desired, AMERICAN can provide special assembly tools and rigging which can be used for assembling most pipes of all sizes (Photo 5). These tools consist of a heavy-duty roller chain hoist, a steel pipe-end hook and snatch block, and associated wire rope and chain tackle (Photo 5) to attach all the rigging together to effect “double line” assembly from the top of the pipe (Photo 6). The snatch block pulley and twin line rigging approximately doubles the assembly force from the strong come- along, making possi- ble the assembly of up to 64" full-length pipe joints from the top of the pipe (Photo 7). Fittings and Short Pipes Push-on fitting or short pipe joint assembly is basically the same as that of standard length pipe, though special rigging may be necessary to hold these short items reasonably stable for assembly. See also Push-On Fittings Assembly Instructions in Section 4. Field Rounding Occasionally, field rounding of pipe ends may be necessary to accomplish assembly, particularly when large-diameter pipes are cut to be assembled into mechanical joints or couplings. Need for rounding in assembly of mechanical or stuffing-box-type joints can be predetermined by a difficulty in sliding the gland or end ring over the end of the pipe. Rounding may be accomplished in the fol- lowing manner using a mechanical jack and shaped blocks. (Note: This procedure may also be used with the assemblies involving push-on joint pipe, fittings, valves, etc.; how- ever, rounding is less frequently necessary for assembly of push-on joints.)

Note: Field rounding operations should be conducted without backfill on any part of large-diameter pipes and prior to encasing any part of pipe in concrete. If the inside of the pipe cannot be accessed to remove jack- ing materials, pipe ends can alternatively be rounded using external clamping means. 1. Measure/determine the minimum (minor) diameter of the ends to be rounded. 2. Place the jack and the shaped blocks in line with the minor diameter as shown in the attached sketch using a sound 4"x4" spacer timber cut square to the required length to take up the space. 3. Apply a load carefully with the jack only until the “minimum diameter equals the maximum diameter,” or until the gland will easily slip over the end. No more jacking should be attempted or necessary - DO NOT ATTEMPT TO PERMANENTLY ROUND END. 4. After the joint is completely assem- bled and the bolts (if involved) are uniformly tightened to the required torque, carefully relax and remove the jack and timbers from the pipe.

"!# 2-14 Spade or Crowbar Method This is applicable to the smaller sizes of AMERICAN Fastite Joint Pipe, and con- sists of centering the lubricated end of the entering pipe in the gasket and then pushing against the bell face of the enter- ing pipe with a spade or crowbar driven into the ground in front of the bell face. This method requires the trench bottom to be fairly firm soil. The method may not be effective in a rocky trench or with a trench that is soft, muddy or sandy. A wooden block between the bell face and the pry bar may increase the leverage. Easier assembly is effected if the pipe is suspended an inch or so off the bottom of the trench. Backhoe and Heavy Equipment Methods These methods are usually applicable to the intermediate and larger sizes of AMERICAN Fastite Joint Pipe where the bar method might not be effective. It consists of centering the end of the enter- ing pipe in the gasket as the pipe to be assembled is suspended from the back- hoe. Then it can be pulled into the adjoin- ing socket with the pipe sling by moving the backhoe arm toward the previously assembled pipe. In other instances, the pipe may be assembled by placing the backhoe or other earth mover bucket or blade against the bell face of the entering pipe and pushing it into the socket. When pushing against the bell face, care should be taken to avoid very small contact areas and possible damage to the pipe bells or spigots. Wood cushions between the backhoe bucket and the pipe are particu- larly effective in preventing damage.
