BACKGROUND: Refer to the Water Main Replacement Overview for background information. In August 2018, the City Commission authorized staff to execute KPWSLF Project No. 2957 in the amount of $4,250,000. Two projects were bid as follows: • Project 1: Construction by Smoky Hill, LLC with a bid amount of $2,097,103 • Project 2: Construction by Stevens Contractors, Inc. with a bid amount of $1,516,587 In November 2018, the City entered into an agreement with Stevens Contractors, Inc. for the amount of $1,516,587, which included the replacement of approximately 2.7 miles (4,710 linear feet (L.F.) of 12 -inch, 5 L.F. of 10 -inch, 4,614 L.F. of 8 -inch, and 4,700 L.F. of 6 -inch) of water main replacements. In July 2019, Change Order No. 1 was approved to add approximately 0.45 miles (1,300 L.F. of 8 -inch and 1,050 L.F. of 6 -inch) of water main replacements, which allowed the KPWSLF loan amount to be better utilized. The Contract Price was increased by $234,507, and the Contract Time was increased by 80 calendar days. The additional work was priced per the bid letting unit prices and was located in the vicinity of work being performed by the Contractor. The attached Change Order No. 2 adjusts the contract's quantities to reflect actual quantities installed, and additional work completed at Bond and Fifth Streets and Charlotte Avenue between Highland Avenue and Ninth Street Place by the Contractor. Change Order No. 2 also revises the Contract Time, including time for the increase in actual quantities installed and additional work at OCCK on Schilling Road. During construction, decisions and adjustments often have to be made in real-time to respond to conditions identified in the field. Much of Salina's water infrastructure was constructed between 1900 and 1960, and there are no record drawings available to determine field conditions. Due to differences between the plans and actual field conditions encountered, several field changes were necessary to construct the project, which included additional water pipeline footage, valves, and fire hydrants, removing and replacing 24 -inch meter pits in new locations, and moving tie- in locations to avoid below ground conflicts. Bond Street and Fifth Street Additional concrete and asphalt pavement, curb and gutter, sidewalk, and wheelchair ramps were ocation, which added 118.8 L.F. of 6- removed and replaced. This was the result of moving a tie-in l inch water pipeline that was under the street, sidewalk, and wheelchair ramps. The unit prices are from the Salina Public Works Fee Schedule, Resolution No 18-7593. The cost breakdown is as follows: 8 -inch Concrete Pavement: Replace Asphalt: Curb & Gutter: Sidewalk: Wheelchair Ramp Type I: 83.3 S.F. @ $8.251S.F. = 131.5 S.F. @ $9.50/S.F. = 19.0 L.F. @ $30.00/L.

The location of the new 6 -inch line was re-routed out into the street to maintain a 10 -foot clearance between a sanitary sewer manhole and the new water pipeline, per the Kansas Department of Health and Environment design standards. The unit prices are from the Salina Public Works Fee Schedule, Resolution No 18- 7593. The cost breakdown is as follows: Pavement Sawing: 101 L.F. @ $4.101L.

Changes in Contract Time is as follows: Additional Time for work at OCCK 1710 West SchillingRoad The Contractor had mobilized to this area, staked out the location of the new water pipeline per the plans, saw cut and removed pavement, located existing utilities, and installed a portion of the new water pipeline. A main break occurred on the existing 6 -inch water pipeline under a loading dock on the north side of the building. The existing water pipeline that broke was installed in 2014. Staff determined that to avoid future costly breaks under the loading dock, it would be a most cost-effective and long-term solution to reroute the water pipeline around the loading dock. Additional time was required to lay out the new location of the water pipeline, exposing utilities and mobilizing in and out of the work area. A total of 14 additional calendar days is proposed for this delay. In addition, a total of 95 calendar days is proposed for the increase in actual quantities installed and additional work completed by the Contractor, resulting in the Contract Time being increased by 109 calendar days.

Ash Street P.O. Box 1276 Salina, Kansas 67402 Salina, KS 67462 12 Martha A. Tasker, Director of Ctilites Quentin Robl, Owner Melissa Rose Hodges, Mayor Date Date Attest: city Clerk Water Main Replacement Overview February 22, 2021 The 2007 Water Distribution Water Model identified existing cast iron water mains that required replacement. In 2010, the City Commission approved $20 Million to be debt- financed for Water Main Replacements. It was anticipated that $4 Million would be completed each year and would be divided into projects to allow local/multiple contractors to complete the projects and potentially reduce the project construction time. Beyond the initial $20 Million of water main replacements, the intention was to continue the annual water main replacements utilizing cash on hand, which is scheduled to begin in 2021 at $2.0 Million per year. The water distribution system consists of 340 miles of water mains ranging in size from 2 -inch to 30 -inch diameter pipes. The original distribution system was constructed in the early 1900s, and the majority of that construction took place in the early 1900s through the 1960s. The water main material was cast iron, which was cast in sand molds. These old sand cast iron water mains were not uniform in size and were not cement -lined, which resulted in a rough interior of the water mains, which provides a surface for iron bacteria to attach to. The water system consists of 195 miles of cast iron water mains (60% of total water mains), of which 133 miles are 6 -inches or smaller in diameter. Old, unlined cast iron water mains often develop tuberculation that gradually constricts flow and causes water flow discoloration due to corrosion products. The results of tuberculation are low fire flows and the presence of iron bacteria, which causes taste and odor complaints. Fire hydrant flushing and other cleaning methods can be performed to reduce tuberculation; however, re -growth of the incrustations is very rapid and flushing and cleaning are not permanent solutions. Tuberculation is problematic in the water mains that are 6 -inch and smaller, over 50 years in age, and where velocities in the water mains are low. Water main replacements are necessary when preventative maintenance activities are no longer effective. The status of the water main replacement projects are as follows: Project/Construction Date Cost Miles Phase 1 (2010 — 2011) $ 776,239 2.0 Phase II 2011 -- 2012 $ 993,760 2.6 Phase III 2013 — 2015 $ 1,423,680 2.0 Phase IV 2013 — 2015 $ 1,222,047 3.5 Phase V (2013 — 2015) $ 1,375,349 3.5 Phase VI (2014 — 2016) $ 1,941,432 4.5 Phase VII (2014 — 2016) $ 2,340,146 4.1 2016 (2016 — 2018) $ 2,104,025 2.9 2017 Project No. 1 2019 — 2020 $ 2,126,003 3.7 2017 Project No. 2 2019 — 2020 $ 1,903,416 3.2 2019 Project No. 1 2021 — 2022 $ 1,871,700 2.6 2019 Project No. 2 2021 — 2022 1,998,39A 3.0 Total $20,076,121 37.6 A total of $20,076,121 has been financed over a ten year period, which totals 37.6 miles of water main replacements. This is an average of 3.76 miles per year at a cost of $533,939 per mile, or an annual cost of $2,007,612.
