The asphalt, base, and header curb overruns are due to drive transitions needed to achieve existing grade into private property (at 5 12% slope), quantity adjustments needed for side street concrete to asphalt transitions, and areas where header curb lengths needed to be extended to better serve the purpose of holding back elevated existing grounds,and make sidewalk surfaces better defined to the pedestrian. The traffic signalization overruns were due to relocated or added pedestrian signal poles &buttons at Brawner Parkway, Gollihar, and Foley Dr. (which included additional 24" drill shaft foundation depths,and wiring),and an error in the quantity billed for the Bid Item B-51 Foundation for Traffic Signal TY 36B (36" Drill Shaft)(15.2ft/EA). only 15.2VF should have been billed for this task, rather than 91VF. In the field adjustments for more accessible(ADA compliant)placement of pedestrian push buttons were needed as traffic signal pole placements were adjusted to maneuver around existing utilities, and foundations.Some of these adjustments caused the proposed placement of the push buttons on the new traffic signal poles to not comply with MUTCD & ADA standards (such as: not to exceed max distance to ramp of S UY, comply with height from top of sidewalk of k 42"- 5 48", and clear space to access ped. button with 5 2% slope in all directions),thus requiring relocation to a compliantly placed pedestrian pole. The grass seeding quantity overrun is due to a miscalculation of the plan quantity. How can similar changes be avoided in the future? Additional survey data outside of project ROW needs to be incorporated in the A/E's contract to allow for the calculation of drive transition quantities (especially in areas where proposed roadways are to be lowered to improve drainage). HMAC (and related materials) quantity adjustments are to be expected for the side street transitions due to unknown construction related issues such as utilities installation boundaries changing to facilitate proper alignment/installation, and added tasks requested by property owners (and approved by the City) such as drive add-ons,or alterations. Better traffic signalization plan review during design could have reduced the amount of adjustments that were needed, but alterations due to field conditions during construction are to be expected,and cannot be easily predicted until tasks get underway. The grass seeding quantity miscalculation could have been avoided with better plan quantity review during design. PAGE t Phase 1 Storm Water Bid Item Quantity Overruns Why was this change necessar. The additional Manhole type C was needed to connect an existing unknown storm lateral to the proposed 6'x6' RCB at approximate station 31+50. This lateral connects the back parking lot drain at the Gas Light Apartments, and was not shown on any of the storm water asbuilts. The additional 18" RCP Culvert was needed to align and connect an existing storm drain lateral to the proposed 6'x6' RCB at approximate station 29+50, and also for miscellaneous alignment/length issues during proposed lateral and inlet placements. The additional 36" RCP Culvert was needed to connect the existing 36" storm drain to the proposed improvements at Horne Rd./Kostoryz (approximate station 51+38). The additional Remove RCP Culvert and Backfill with Cement Stabilized Sand was needed due to an existing unknown (abandoned) storm RCP that ran down the west side of Kostoryz from approximate stations 32+08 to 38+69. This abandoned RCP was discovered during excavation for the proposed roadway pavement section. The additional Pre-Construction Exploratory Excavations were needed to identify the exact depth of the existing AT&T duct,and 12" water line that run down the west side of the Kostoryz roadway (between Golhhar and Sunnybrook) to determine if these utilities would conflict with the proposed storm lateral crossing structures, and pavement section. How can similar changes be avoided in the future? Unavoidable, minor field adjustments to storm water RCP quantities during construction are anticipated to properly align&connect existing and proposed facilities. The unknown and abandoned RCP not identified on asbuilts, is commonly encountered during roadway reconstruction projects as old as this section of Kostoryz. The additional Pre-Construction Exploratory Excavations could be avoided by conducting more thorough subsurface utility excavations (SUE) during the design phase of the project. The consultant was instructed to keep the SUE's to a minimum, and to utilize asbuilt data when available. Phase 1 Wastewater Bid Item Ouantity Overruns Why-was this change necessary? The additional Pipe Bursting of Wastewater Line (8" HDPE Pipe) was needed to complete the sanitary sewer improvements to the east down Gollihar Rd. from the Gollihar/Kostoryz intersection. The plan quantity shouId have shown 244 LF rather than 222 LF. The additional Remove and Replace (Open Cut) Wastewater Line (8" PVC) was needed to reroute HEB's two 8"service lines underneath the proposed 8'x8' RCB storm trunk at PAGE approximate stations 41+44 and 48+00. Additional 8" PVC was also needed to properly align & connect to the existing 8" service that runs to the Wind Rash Apartments at approximate station 51+25. The additional Service Line Connections were needed at locations where unknown services had to be connected to the proposed sanitary sewer main. The additional Well Pointing for Manholes,Insertion Pits,and Open Cut was nneeded for the insertion pits used for the pipe bursting to the east down Gollihar Rd.and Foley Dr. How can similar than es be avoided in the future? The additional Pipe Bursting of Wastewater Line (8" HDPE Pipe) would have been avoided had a more thorough review of the plan quantity taken place during the design submittal phases(correct quantity of 244LF was shown on plans,but not reflected in Bid Item quantity of 222LF). The additional Remove and Replace (Open Cut) Wastewater Line (8" PVC) was unavoidable due to HEB installing their 8" sanitary sewer service lines at an elevation that was in conflict with the 8'x8' RCB storm drain placement, and field adjustments needed for proper alignment & connection to the existing Wind Rush Apartments 8" service. The additional Service Line Connections were unavoidable due to sanitary sewer asbuilts not including this information, and some connections having multiple services attached. The additional Well Pointing for Manholes,, Insertion Pits, and Open Cut was unavoidable due to the plan quantity being an educated guess derived from the Geotechnical report on what elevation the ground water will be encountered at. This will fluctuate depending on rainfall. Anticipated Quantity Adjustments-Phase 1 Phase 1 Antici aced Street Quantily Adjustments LAft was this change necessary? The AT&T Fire Protection Water Vault Removal is needed to facilitate the placement of the proposed JRCP section at approximate station 32+30. The vault and supply line are not in service, and need_ to be removed to avoid delay in placing the west side curb & gutter at this location. How can similar changes be avoided in the future? Unavoidable, contractor needs task addressed, and AT&T coordination experiences frequent delays in dealing with project related 'issues. PAGE 3 Phase 1 Anticipated Water Quantity Adjustments Why was this change necessary? The 10OLF of 12" C-900 water line replacement, trench safety, and removal is due to elevation conflict with pavement section. The location is just north of Surmybrook, adjacent to the Fire Station at approximate station 28+00 to 29+00. How can similar-changes be avoided in the future? Unavoidable, given the circumstances. This issue could have been accounted for with more thorough subsurface utility excavations (SUE) during the design phase of the project,but the consultant was instructed to keep the SUE's to a minimum,and to utilize valve measure-down & asbuilt data where available. Valve measure-downs do not accurately reflect line elevations between valve locations, and City Water Department asbuilts are frequently inaccurate regarding line alignment&elevation. Whp was this change necessary? The installation of the 2 - 16" Gate Valves with Boxes rather than the planned 16" Butterfly Valves at the Gollihar intersection was requested by Arnold Longoria (City Water Department). Arnold stated that butterfly valves have been notorious for locking up (and not shutting or opening correctly),especially on the larger water line sizes such as this one. How can similar changes be avoided in the future? Better design submittal reviews and correspondence by the City Water Department to ensure desired repairs get incorporated into the design by the A/E. Why was this change necessary The Hot Line Taps for the 12"x6" & 12"x8" Tapping Sleeve and Valve (TS&V) bid items are needed to connect 2 New Fire Hydrant Assemblies to the 12" water amain that runs down the west side of Kostoryz Rd. at approximate stations 56+80 & 53+80, and 8" water line to the 12" main at approximate stations 50+80&59+10.The contractor bid the 12"x6" & 12"x8" TS&V Bid Items with the understanding that the City Water Department would perform the taps on the hot lines (as is stated on the plan sheets). The City Water Department changed its policy shortly after construction began, and no longer would perform hot line taps for the TS&V's, thus creating additional expense for the contractor to install. How can similar than es be avoided in the future? Better design submittal reviews and involvement by the City Water Department to ensure that contract documents reflect current(and future) departmental policies. PAGE Phase 1 Anticipated Storm Water Quantity Adjustments Why was this chan a necessary? The 2- 12" RCP and Type A manhole were needed to connect the proposed west side inlet to the proposed 6'x6' storm trunk at approximate station 38+69. The 2 — 12" RCP were used because adequate clear distance over the AT&T duct was not available to run the planned 18" RCP. How can similar changes be avoided in the future? This alignment issue was avoidable, and was thought to have been dealt with during design using SUE elevation data collected at locations where proposed utility improvement structures crossed the AT&T duct. Incorrect survey data, or skewed data transfer is the reason for this issue. Accurate survey data collection &recording would have facilitated the correct design for this storm lateral. Anticipated Quantity Adjustments-Phase 2 Phase 2 Anticipated Water Ouantitv Adjustments Wh was this char a necessary? The 40OLF of possible 12" water line and related bid item quantity adjustments are for unknown areas within Phase 2 west side construction boundaries where the line elevation may be in conflict with the JRCP section.. This has posed problems within Phase 1,so it is anticipated to be an issue within Phase 2 as well. How can similar changes be avoided,in the future? Unavoidable, given the circumstances. This issue could have been accounted for with more thorough subsurface utility excavations (SUE) during the design phase of the project,but the consultant was instructed to keep the SUE's to a minimum,and to utilize valve measure-down & asbuilt data where available. Valve measure-downs do not accurately reflect line elevations between valve locations, and City Water Department asbuilts are frequently inaccurate regarding line alignment&elevation. MY was this change necessary? The 20OLF of 12" C-900 water line and related bid items for the McArdle/Kostoryz intersection was requested by Arnold Longoria (City Water Department) to replace existing cast iron line & fittings, and to straighten the alignment through the intersection. How can similar chan es be avoided in the future? Better design submittal reviews and correspondence by the City Water Department to ensure desired repairs get incorporated into the design by the A/E. PAGE Why was this change necessary? The 80LF of 12" C-900 water line and related bid items for the SPID/Kostoryz intersection was requested by Arnold Longoria (City Water Department) to replace existing cast iron line & fittings, and to straighten the alignment approaching the intersection. How can similar changes be avoided in the future? Better design submittal reviews and correspondence by the City Water Department to ensure desired repairs get incorporated into the design by the A/E. Why was this change necessary? The Hot Line Taps for 12"x6" Tapping Sleeve and Valve (TS&V) bid item is needed to connect 3 New Fire Hydrant Assemblies to the 12" water line that runs down the west side of Kostoryz Rd. at approximate stations 4+10,10+00, and 17+00.The contractor bid the 12"x6" Tapping Sleeve and Valve Bid Item with the understanding that the City Water Department would perform the taps on the hot lines (as is stated on the plan sheets).The City Water Department changed its policy shortly after construction began, and no longer would perform hot line taps for the TS&V's, thus creating additional expense for the contractor to install. How can similar changes be avoided in the future? Better design submittal reviews and involvement by the City Water Department to ensure that contract documents reflect current(and future) departmental policies. Phase 2.Anticipated Street Quantfty Adjustments Why was this change necessary? The signalization of the McArdle/Kostoryz intersection is needed due to the existing signal pole foundations not being in compliance with MUTCD distance requirements from face of curb (z 2' is minimum,if z 3' cannot be achieved), and height above top of curb (s 4"). It has also been requested that this intersection get new signalization by Tony Salinas (City Traffic Signals) due to the existing outdated components,and the fact that it is the only signalized intersection within the project boundaries that is not being completely improved. How can similar changes be avoided in the future? Better design submittal reviews and correspondence by the City Traffic Engineering & Signals Departments to ensure desired improvements get incorporated into the design by the A/E. During design the A/E was instructed to avoid additional expenses by only improving signalization at intersections where existing signalization is in conflict with the planned widening of the roadway. The signalization at this intersection was not addressed due to the existing pole foundations not having to be moved to accommodate the widening of the roadway (roadway was already widened at this location,so back of curb alignment is staying approximately the same). During roadway demolition and JRCP placement, it became apparent that the street improvements (relative to the existing signalization) would not be in compliance with MUTCD standards (neither PAGE 6 were the existing conditions in relation to distance of objects from face of curb), and the decision was made to improve the signalization at this intersection as is being done at Foley,Gollihar,Horne,and Brawner. Why was this change necessary? The 8" proof rolled non-yielding subgrade quantity adjustment is due to an incorrect planned quantity in the contract documents. How can similar changes be avoided in the future? Better A/E plan quantity reviews during design would avoid this issue. Why was this change necessary? The pre-construction exploratory excavations quantity adjustment is needed to evaluate the elevation of the AT&T ducts that run down the west side of the Kostoryz Roadway from Mansheim to SPID. The AT&T duct elevations have conflicted with the JRCP section in Phase 1, and it is anticipated to be an issue in unknown areas of Phase 2 (possibly within the west side of the roadway,and under west side sidewalk). How can similar chan es be avoided in the future? Unavoidable, given the circumstances. This issue could have been accounted for with more thorough subsurface utility excavations (SUE'S) during the design phase of the project,but the consultant was instructed to keep the SUE'S to a minimum,and to utilize asbuilt data where available. The AT&T duct was excavated (SUE's) at locations where utility structures crossed it,but has been encountered at conflicting elevations between these areas. The duct should have been SUE'd at 100ft to 200ft intervals, as well as at crossing structures, to ensure design compatibility. AT&T asbuilts were old and inaccurate regarding duct elevations,and alignment. My was this change necessary? The bid item quantity adjustments for drive transitions and apron/rip rap are needed to facilitate the construction of asphalt, and concrete drive transitions into private properties where the Kostoryz Roadway has been significantly lowered to improve drainage (approximately from Mansheim to SPID). These transitions are not to exceed a 12.% slope, and require considerable distance into the properties to achieve existing grades.This issue was not recognized in design,and is a direct result of the lowering of the roadway. How can similar changes be avoided in the future? Additional survey data outside of project ROW needs to'be incorporated in the A/E's contract to allow for the calculation of drive transition quantities (especially in areas where proposed roadways are to be lowered to improve drainage).

Please be aware that the lead time on the material in Change Order 11 required for the signaling of the McArdle intersection has an estimated 12-14 week lead time. This extends past the contract completion date. It is Texas Sterling's understanding the new signaling work associated with Change Order 11 will not inhibit the opening of the roadway and project closeout procedures including but not limited to stopping contract time, punch lists completion, final inspections, retainage (with the exception of retainage associated with the intersection signaling), and all other procedures in order to obtain complete project closeout. If this is not the understanding of the city than additional contract time will need to be added to accomodate the work associated with Change Order 11.
