This Assembly Package is for adjustinent of City of Denton facilities located within the IH35E Managed Lanes corridor. Based on review of existing city facilities located within the limits of the attached plan set, AGL has analyzed the following raw water lines to conflict with the proposed IH 35E widening: .,��I�ai�tz��,,,�"��,mmaa�",Conflict 18:;� ��4��-i�C�� The relocation of Conflict ID 503-001 under this PUAA shall consist of the installation of approximately 60 lf. of 30" RCPP and 4 30" resilient wedge gate valves at approximately ML Station 1456+97 and 1456+35. The proposed 30" raw water valves and pipes are being installed because the existing 30" raw water line conflicts with the proposed widening of IH 35E. The valves are being installed prior to the remaining relocation to avoid an outage of raw water during the peak flow season. T11e Tee and additional valves will provide an easily accessible tie in point for the proposed crossing and will allow City of Denton to maintain raw water flow. Two 30" valves and a tee will be installed on both the southbound and northbound sections. A UAAA with the remaining relocation for conflict 503-001 crossing IH35E will be submitted at a later date. Adjustment of Conflict ID 503-002: The relocation of Conflict ID 503-002 under this PUAA shall consist of the installation of approximately 150 If. of 30" RCPP, 4 30" resilient wedge gate valves and 4 30" to 27" eccentric reducers at approximately ML Station 1468+72 and 1473+45. The proposed 30" raw water valve and pipes are being installed because tlie existing 27" raw water line conflicts with tl�e proposed widening of IH 35E.

Protection of Existing Structures and Utilities: Prior to the start of construction and preparation of pipe layout sheets, the Utility Contractor shall communicate with the local representative of the utility companies including, but not limited to the oil companies, gas company, electric company, telephone company, water utilities, sanitary sewer utilities, and any other public and private utility companies in the location of the proposed construction in order to obtain the assistance of the utility companies in locating utility lines and in the avoidance of conflicts with utility lines. The Utility Contractor shall uncover and determine the elevation and location of conflicts well ahead of the manufacture of the pipe. The Consultant has shown the estimated location of existing utilities as determined from field surveys and record data from utility companies. The fact that some utilities are not shown or are incorrectly shown in no way relieves the Utility Contractor from his responsibility to locate all existing utilities. 2. The Utility Contractor shall advise the Consultant of any existing utilities which are not shown on the plans, incorrectly shown, and which "affect the pipe layout." Utility Contractor shall also propose a resolution of the utility conflict. The Consultant will decide if the existing utility should be relocated, or whether the proposed pipeline location will be revised. 3. Utilities which "affect the pipe layout" will be interpreted by the Consultant as follows: a. Utilities which conflict with the grade of the proposed pipe will be interpreted as "affecting the pipe layout." b. Utilities which would conflict with operations and maintenance of the proposed pipe will be interpreted as "affecting the pipe layout." 4. Where excavation endangers adjacent slopes, structures and utilities, the Utility Contractor shall carefully support and protect such structures and/or utilities so that there shall be no damage. 5.

Dewater excavations so that the work is performed in the "dry." Bailing, pumping, and dewatering shall be at the Utility Contractor's expense. Use coarse gravel instead of embedment material under the to provide for the free drainage and flow of water in the pipe trench, where it is necessary, in order to keep the water level below the pipe barrel and bell holes for joints. The water removed from trenches shall be conducted to natural drainage ways, drains, or storm sewers in such a manner as to prevent damage to adjacent property or to the public. Pumps of ample capacity and in duplicate must be provided to insure that once an excavation is made dry, the water is kept down unti) that part of the work under construction is completed. 4. It is intended that the line be laid to the grades as shown on the plans. The precise and detailed pipe layout is to be prepared by the Utility Contractor and submitted to the Pipeline Excavation and Backfill 02202 - 4, IH 35 E Segment 3 Utilities Dallas/Denton County January 2015 UT-20 & UT-49 City of Denton Raw Water Consultant and Owner for information and review. The responsibility for the workability of the detailed layout remains with the Utility Contractor. High points shall be located at air valves and the pipe sections containing air valves shall have a horizontal grade. At drainage crossings, the depth of cut shall be increased to prevent un'covering of the pipe by surface erosion, as shown on the plans. 5. Where unforeseen conditions warrant a revised grade during construction, the Utility Contractor shall submit a revised pipe layout to the Consultant for approval. No intermediate "highs" or "lows" will be allowed in the pipe grade without the approval of the Consultant. B. Pipe Trench: 1. For the purpose of this specification, the "pipe zone" shall be defined as the zone from the bottom of the trench to 6 inches above the top of the pipe. 2. The trench walls in the "pipe zone" shall be vertical. 3. Trench width shall be as follows: �..��._��_��.� Trench W� I Maximu�.�.��. Pipe Diameter Minimum � m idth Trench Width Greater than 24°_ Pi�e O.D.µplus 24" ' Pipe O.D.�X � p p plus 36" 4. Trench walls above the pipe zone may be laid back or benched where room permits as necessary to meet the requirements of OSHA. S. Where the character of the trench walls is loose, unstable, saturated soft clays, quicksand, or otherwise unable to provide adequate side support to maintain the required pipe deflection, the Utility Contractor shall modify the trenching and backfill to keep the pipe within the limits of the specified deflection. The Utility Contractor shall widen the trench excavation one pipe diameter on each side of the pipe. The trench shall then be backfilled with coarse gravel to the top of the pipe. The coarse gravel shall be compacted to 95 percent maximum density as measured by ASTM D4253. Care shall be used so that the exterior pipe coating is not damaged. Concrete encasement, soil cement, or some other method approved by the Consultant, may be used in lieu of this procedure. C. Pipe Foundation: 1. Excavate the trench to an even grade so that the full length of the pipe barrel is supported and joints make up properly. Excavate the trench to the line and grade indicated and as directed by the Consultant. Grades shall be uniform between high points and low points to eliminate intermediate "highs and lows." 2. For 24-inch and larger pipe, the trench shall be "rough cut" a minimum of 6 inches ' below the bottom of the pipe. The "rough cut" dimension shall be increased as necessary to provide a minimum clearance of 2 inches from the bottom of the trench to the bottom of the bells, flanges, valves, fittings, etc. 3. The entire foundation area in the bottom of all excavations shall be firm, stable material. Loose material shall be removed leaving a clean flat trench bottom and Pipeline Excavation and Backfill . , 02202 - 5 IH 35 E Segment 3 Utilities Dallas/Denton County January 2015 UT-20 & UT-49 City of Denton Raw Water material shall not be disturbed below required sub grade except as hereinafter described. If the subgrade is soft, spongy, disintegrated, or where the character of the foundation materials is such that a proper foundation cannot be obtained at the elevation specified, then when directed by'the Consultant the Utility Contractor shall deepen the excavation to a depth where a satisfactory foundation can be obtained. The sub grade shall then be brought back to the required grade with course gravel, thoroughly compacted to 95 percent of maximum density in accordance with ASTM D4253. D. Correcting Faulty Grade: If the trench is excavated to a faulty grade (at a lower elevation than indicated), correct the faulty grade as specified below: 1. In uniform, stable dry soils, correct the faulty grade with granular embedment material thoroughly compacted to 95 percent of maximum density. 2. In soft spongy disintegrated soils or where necessary to allow proper drainage, correct the faulty grade with course gravel compacted to 95 percent of maximum density. E. Pipe Clearance in Rock: Remove ledge rock, rock fragments, or unyielding shale or marl to provide a clearance of at least 6 inches below the parts of the pipe, valves or fittings. Provide adequate clearance for properlyjointing pipe laid in rock trenches at bell holes. Refill the excavation to grade with granular embedment material. F. Blasting Procedure: Blasting will not be allowed. G. Bell Holes Required: Bell holes of ample dimension shall be dug in trenches at each joint of pipe to permit the jointing to be made properly, visually inspected, and so that the pipe will rest on the full length of the barrel. H. Care of Surface Material for Reuse: Surface materials such as top soil in its natural state, suitable for reuse in restoring the excavated surface, shall be kept separate from the general excavation material. The top 12 inches of the trench backfill shall be topsoil. Save the topsoil to be used as backfill of the top 12 inches of the trench after pipe laying. Where the natural topsoil is less than 12 inches deep and with the approval of the Consultant, the Utility Contractor may strip less than 12 inches of topsoil. Manner of Piling Excavated Material: Place excavated material so that work is not endangered or interferes with public traffic or other construction. Do not place excavated material over buried pipelines or existing utilities unless adequate provisions are made to protect those pipelines and/or utilities. Roads and driveways must be kept open in every case. Keep drainage channels clear of obstructions or make other satisfactory provisions for drainage. J. Trenching by Machine or by Hand: The use of trench digging machinery is approved except in places where operations of same will cause damage to existing structures or pipelines above or below ground, in which case employ hand methods. K. Open Trench: Consultant's Representative shall have the right to limit the amount of trench which may be opened or partially opened at any time in advance of the completed line; and also the amount of trench left not backfilled. Not over 500 feet of trench in open country or pasture land shall be opened at any one time, and not more than 150 feet of trench in populated areas shall be left open unless otherwise permitted in writing by the Consultant. Backfill and/or protect trenches as necessary to prevent injury to livestock, adjacent Pipeline Excavation and Backfill . . 02202 - 6 IH 35 E Segment 3 Utilities Dallas/Denton County January 2015 UT-20 & UT-49 City of Denton Raw Water property, and the public. Trenches left open overnight in public areas shall be fenced with a•dequate construction fencing. No trenches shall be left open overnight in streets. L. Structural Excavation,: Excavation shall extend a sufficient distance from walls �nd footings to allow for form installation and inspection, except where concrete for walls and footings are authorized or required to be deposited directly against excavated surfaces. Where excavation, through the fault of the Utility Contractor, is made below the elevation specified or directed by the Consultant, restore the excavation to the proper elevation with stabilized backfill (lean concrete) or other approved material at the Utility Contractor's expense. 3.02 BACKFILLING OF TRENCHES OUTSIDE ROADWAYS A. General: This Section of the specification is intended to cover the requirements for trench backfill where trench is in open fields, unimproved alleys, fields, and other similar open areas outside of existing or proposed public and private roadways. B. Time of Backfilling: Backfill operations shall immediately follow pipe jointing, joint coating application, and curing. C. Braced and Sheeted Trenches: Remove sheeting and shoring as backfilling operations progress. Incorporate methods so that a good bond is obtained between the backfill material and the undisturbed trench walls. D. Protection of Pipe During Backfilling Operations: Take the necessary precautions to protect the pipe during backfilling operations. Take care to prevent damage to the pipe or to the pipe coating, and repair any damaged pipe before being "covered up." Backfill the trench to prevent the deformation or otherwise deflection of the cylindrical shape of the pipe by more than the allowable pipe deflection as specified elsewhere. Use methods such as stulling or ellipsing as necessary. E. Site and Preparation: In addition to clearing and grubbing of brush and trees along the right of way for this project, alteration to the topography shall be done if indicated on the Plans, at the locations and to the extent shown. F. Backfill Procedure in the Pipe Zone for Semi Rigid Pipe: 1. Place the first lift of granular embedment material to a depth slightly above the bottom of pipe grade. Lay pipe on this embedment material to the indicated grade. Provide bell holes to permit the pipe to rest on the ful► length of the barrel and to permit joint make-up and coating. 2. For semi-rigid pipe construction, extend the embedment material from the bottom of the trench to 6 inches over the top of pipe. 3. Place the second lift of embedment material, uniformly on both sides of the pipe to a loose depth of one-half of the outside diameter of the pipe, taking precautions not to disturb the pipe alignment. Compact the second lift of embedment material using vibration or mechanical tamping to produce a uniformly blended and compacted backfill. Utility Contractor shall take precautions to ensure no voids occur under the haunches of the pipe and to prevent disturbance of the pipe alignment. 4. Place the third lift of granular embedment material in the trench simultaneously and evenly on both sides of the pipe for the full width of the trench to an elevation of 6 inches above the top of the pipe using vibration or mechanical tamping. Compaction of P�peline Excavation and Backfill • w 02202 - 7 IH 35 E Segment 3 Utilities Dallas/Denton County January 2015 UT-20 & UT-49 City of Denton Raw Water granular embedment in this zone shall be at a minimum of 95 percent Maximum Density in accordance with ASTM D4253. 5. After placement and.compaction of the third lift, add additional granular embedment to fill the voids and strike-off the embedment to be level at an elevation 6 inches above the pipe. G. Procedure Above Pipe Zone: Mechanical compaction may be utilized. Place the ordinary backfill material above the pipe zone in lifts not exceeding 18 inches loose depth, up to 12 inches below the surface, and compacted to 90 percent Standard Proctor density in areas outside of existing or proposed roadways. The Utility Contractor shall be responsible for any damage which may occur to the pipe using his method of compaction. H. Surface Material Replacement: 1. The top 12 inches of the trench backfill shall be composed of the original surface material or topsoil excavated from the trench. Place the topsoil over the consolidated trench backfill material and neatly round over the trench to a sufficient height to allow settlement to grade after consolidation. Grade the surface to allow drainage in the same manner as existed prior to construction. 2. Topsoil shall not contain rocks or clods larger than those adjacent to the trench in the undisturbed condition. I. Backfill Around Structures: 1. After completion of foundations, walls, vault ,etc., remove forms and clean excavation of debris or other objectionable matter prior to placing backfill. 2. In areas where structures such as slabs, foundations, or pipes are to be constructed on backfill, backfill shall be lean concrete or; flowable fill, unless otherwise indicated. 3. For pre-cast concrete structures, mechanically tamp earth backfill around and over structures, using select material, and placed in layers not to exceed 8 inches, loose thickness. Bring material to within 2 percent of optimum moisture content and compact each layer to a uniform density of not less than 95 percent of maximum density as determined by ASTM D698. Laboratory control shall be used to secure compliance with this requirement. J. Inspection and Test Pits: 1. Excavate test pits after the embedment has been placed and compacted in the pipe zone for the purpose of taking field density tests and inspecting the haunch areas under the pipe for voids. 2. Excavate the test pits to a depth and area of sufficient size to allow the inspector to visually inspect the haunch area of the pipe for voids or loose material next to the pipe and to make a field density test. Provide a safety trench shield to protect the inspector while in the pit. 3. After inspection, backfill and compact the test pit area in accordance with the applicable specification herein. 4. Dig one test pit for inspection of each day's work if deemed necessary or may be required more or less frequently as determined by the Owner's representative. Repair Pipeline Excavation and Backfill • . 02202 - 8 IH 35 E Segment 3 Utilities Dallas/Denton County January 2015 UT-20 & UT-49 City of Denton Raw Water and replace areas which are found not to be in compliance with the specification requirements, until satisfactory results are consistently and uniformly attained. 5. Provide special attention to assure that the material flows under the pipe haunches. This may require the removal of pipe joints to observe the results and make density tests. Pipe laying shall not begin until satisfactory results are achieved by the Utility Contractor's proposed method. 3.03 BACKFILL PROCEDURE FOR PUBLIC AND PRIVATE ROADS A. Trench excavation, pipe laying, backfill within the pipe zone and other generai requirements shall be as indicated for trenches outside roadways. Backfill material above the pipe zone for existing roads including City Roads, County Roads, paved or improved private roads, driveways, and any proposed roads as indicated shall consist of granular embedment material for the full depth of the trench to subgrade of flexible base.

Pipe Jointing 1. General Bar-Wrapped Concrete Cylinder Pipe and Fittings . 02614 - 7 IH 35 E Segment 3 Utilities Dallas/Denton County January 2015 UT-20 & UT-49 City of Denton Raw Water a. Thoroughly clean the bell and spigot rings before laying each joint of pipe by brushing and wiping. If any damage to the protective coating on the metal has occurred, repair the damage before laying the pipe. Lubricate the gasket and the inside surface of the bell with an approved lubricant (flax soap) which will facilitate the telescoping of the joint. Tightly fit together sections of pipe and exercise care to secure true alignment and grade. When a joint of pipe is being laid, place the gasket on the spigot ring and enter the spigot end of the pipe into the bell of the adjoining pipe and push into position. The inside joint space between ends of the pipe sections shall have an opening within the tolerances as recommended by the Pipe Manufacturer. No "blocking up" of pipe orjoints will be permitted, and if the pipe is not uniformiy supported or the joint not made up properly, remove the joint and properly prepare the trench. After joining, check the position of the gasket with a feeler gauge. If the gasket is out of position, disassemble the joint and repeat the joint laying procedure. b. For interior welded joints, complete backfill before welding. After welding, apply the interior joint coating. 2. Exterior Joints Make the exteriorjoint by placing a joint wrapper around the pipe and secure in place with two metal straps. The wrapper shall be 9 inches wide for pipe 36 inches and larger, and 7 inches wide for smaller pipe, hemmed on each side. The wrapper shall be fiberglass reinforced or burlap cloth, with lengths encircling the pipe, leaving enough opening between ends to allow the mortar to be poured inside the wrapper into the joint. Fill the joint with mortar from one side in one continuous operation until the grout has flowed entirely around the pipe. During the filling of the joint, pat or manipulate the sides of the wrapper to settle the mortar and expel any entrapped air. Leave wrappers in place undisturbed until the mortar has set-up. 3. Interior Joints a. Upon completion of backfilling of the pipe trench, fill the inside joint recess with a stiff cement mortar. Prior to placing of mortar, clean out dirt or trash that has collected in the joint, and moisten the concrete surfaces of the joint space by spraying or brushing with a wet brush. Where the mortar joint opening is 1 inch or wider, such as where trimmed spigots are required, apply a bonding agent to mortar and steel surface prior to placing joint mortar. Ram or pack the stiff mortar into the joint space and take extreme care to insure that no voids remain in the joint space. After the joint has been filled, level the surfaces of the joint mortar with the interior surfaces of the pipe with a steel trowel so that the surface is smooth. 4. Welded Joints Pipe 36 inches and smaller shall be welded from the outside using the following procedures: 1). Telescope together the joints to be welded with a rubber gasket as specified above and align perfectly with the adjacent section of pipe. Accomplish welding by laying a filler rod between the steel bell of one section and the steel spigot of the other, and welding the bell to the outside of the spigot. Use no less than three complete passes to make the weld. When the joint weld is completed, Bar-Wrapped Concrete Cylinder Pipe and Fittings � . 02614 - 8 IH 35 E Segment 3 Utilities Dallas/Denton County January 2015 UT-20 & UT-49 City of Denton Raw Water pour the exterior joint with mortar as specified above. After all sections are in final position, fill the interiorjoint as specified above. Welded joints shall meet the requirements of AWWA Manual M9. b. Pipe 42 inches and larger shall be welded from the inside, using the following procedures: 1). Complete the exterior joint mortar application and allow it fully set and cure prior to backfill and welding. Joint spigots shall be trimmed where the stress in the gasket groove exceeds 12,000 psi due to axial thrust load. Trim the joint ring behind the gasket groove. After the adjacent pipe sections are aligned and tack welded, weld the bell to the spigot with a full fillet weld. Welded joints shall meet the requirements of AWWA Manual M9. When the joint weld is completed, grout the inside joint, pour the exteriorjoint with mortar as specified above. c. General weld requirements shall be as follows: 1). Weld joints in accordance with the AWWA C206 for Field Welding �of Steel Water Pipe. Unless otherwise specified, welds shall be full circle fillet welds. 2). Adequate provisions for reducing temperature stresses shall be the responsibility of the Utility Contractor. 3). After the pipe have been joined and properly aligned and prior to the start of the welding procedure, the spigot and bell shall be made essentially concentric by jacking, shimming, or tacking to obtain clearance tolerance around the periphery of the joint. In no case shall the clearance tolerance be permitted to accumulate. 4). Before welding, thoroughly clean pipe ends. Weld pipe by machine or by the manual shielded electric arc process. Welding shall be performed so as not to damage lining or coating. Cover the coating as necessary to protect from welding. 5). Furnish labor, equipment, tools and supplies, including shielded type welding rod. Protect welding rod from any deterioration prior to its use. If any portion of a box or carton is damaged, reject the entire box or carton. 6). In all hand welding, the metal shall be deposited in successive layers. For hand welds, not more than 1/8 inch of inetal shall be deposited in each pass. Each pass except the final one, whether in butt or fillet welds, shall be thoroughly bobbed or peened to relieve shrinkage stresses and to remove dirt, slag, or flux before the succeeding bead is applied. Each pass shall be thoroughly fused into the plates at each side of the welding groove or fillet and shall not be permitted to pile up in the center of the weld. Undercutting along the side shall not be permitted. 7). Welds shall be free from pin holes, non-metallic inclusions, air pockets, undercutting and/or any other defects. 8). If the ends of the pipe are laminated, split or damaged to the extent that satisfactory welding contact cannot be obtained, remove the pipe from the line. Bar-Wrapped Concrete Cylinder Pipe and Fittings � � 02614 - 9 IH 35 E Segment 3 Utilities Dallas/Denton County January 2015 UT-20 & UT-49 City of Denton Raw Water 9). Furnish each welder employed with a steel stencil for marking the welds, so that the work of each welder may be identified. Have each welder stencil the pipe adjacent to the weld with the stencil assigned to him. In the event any welder leaves the job, his stencil shall be voided and not duplicated if anbther welder is employed. 10).Use only competent, skilled and qualified workmen. Each welder employed by the Utility Contractor shall be required to satisfactorily pass a welding test in accordance with AWWA C-206 before being allowed to weld on the pipeline. 11).After each welder has qualified in the preliminary tests referred to above, inspections shall be made ofjoints in the line. Any welder making defective welds shall not be allowed to continue to weld. 12). Dye penetrant tests in accordance with ASTM E165, or magnetic particle tests in accordance with ASTM E709, shall be performed by the Utility Contractor's independent testing laboratory on all welded joints. Welds that prove to be defective will be replaced or repaired, whichever is deemed necessary by the Consultant, at Utility Contractor's expense. 13),If the Utility Contractor disagrees with the Consultant's interpretation of welding tests, test sections may be cut from the joint for physical testing. The Utility Contractor shall bear the expense of repairing the joint, regardless of the results of physical testing. The procedure for repairing the joint shall be approved by the Consultant before proceeding. D. Protection of Buried Metal Protect buried ferrous metal such as flanges, nuts, bolts, dresser couplings, etc. by applying two wraps of wax tape in accordance with AWWA C217, and encasing it with flowable fill.

If Utility's facilities are located along a controlled access highway, Utility agrees that ingress and egress for servicing its facilities will be limited to frontage roads where provided, nearby or adjacent public roads and streets, or trails along or near the highway right of way lines which only connect to an intersecting road. Entry may be made to the outer portion of the highway right of way from any one or all access points. Where supports, manholes or other appurtenances of the Utility's facilities are located in medians or interchange areas, access from the through-traffic roadways or ramps will be allowed by permit issued by the State to the Utility setting forth the conditions for policing and other controls to protect highway users. In an emergency situation, if the means of access or service operations as herein provided will not permit emergency repairs as required for the safety and welfare of the public, the Utility shall have a temporary right of access to and from the through-traffic roadways and ramps as necessary to accomplish the required repairs, provided TxDOT is notified immediately when such repairs are initiated and adequate provision is made by Utility for the convenience and safety of highway traffic. Except as expressly provided herein, the Utility's rights of access to the through-traffic roadways and/or ramps shall be subject to the same rules and regulations as apply to the general public. �'° �"�w�� Is�i16tia1. Date Utility Form ROW -U-JUAA-DA (Rev. 11/12) Page 2 of 2 If Utility's facilities are located along a non-controlled access highway, the Utility's rights of ingress and egress to the through-traffic roadways and/or ramps are subject to the same rules and regulations as apply to the general public. Participation in actual costs incurred by the Utility for any future adjustment, removal or relocation of utility facilities required by highway construction shall be in accordance with applicable laws of the State of Texas. It is expressly understood that Utility conducts the new installation, adjustment, removal, and/or relocation at its own risk, and that TxDOT makes no warranties or representations regarding the existence or location of utilities currently within its right of way. The Utility and the State, by execution of this Acknowledgement , do not waive or relinquish any right that they may have under the law. The signatories to this Acknowledgement warrant that each has the authority to enter into this Acknowledgement on behalf of the party represented.
