<br />WS – Item #4 <br /> <br />WORK SESSION STAFF REPORT <br />Work Session Item No. 4 <br /> <br />Date: February 3, 2020 <br /> <br />To: City Council <br /> <br />From: Diane Hankee, City Engineer <br /> Jim Stremel, WSB & Associates <br /> <br />Re: West Shadow Lake Drive Project Change Order No. 2 <br /> <br />Background <br /> <br />On October 8, 2018, the City Council awarded the bid for the West Shadow Lake Area <br />Improvement Project to Geislinger and Sons, Inc. in the amount of $4,940,636.57. Construction <br />has been ongoing since October of 2018. On March 11, 2019 the City Council approved Change <br />Order No. 1 in the amount of $41,849.00 for the extension of concrete curbing. <br /> <br />The 2019 construction season set a record for the number of rainfall events, a total of 39 days. <br />This led to difficult and delayed construction season for the West Shadow Lake Area <br />Improvement Project which required additional maintenance of erosion control measures, <br />pumping of standing water, maintaining the roadway, providing temporary and passable access <br />to residents, and time needed to dry out the site. The contractor met substantial completion 2.5 <br />months late but did not meet the final completion date of November 1, 2019. <br /> <br />Construction of the project is almost complete with the final lift of bituminous and boulevard <br />restoration remaining. Due to the inclement weather and additional time spent to maintain the <br />site, the contractor has requested a final completion date extension to June 26, 2020. Changing <br />the final completion date would be approved by Council through Change Order No. 2. <br /> <br />During the initial construction of the roadbed, and with further exploratory excavations, the <br />project engineers noted that the soils in the north portion of the project met the road subgrade <br />requirements and the typical section was modified from 24 inches of sand to 18 inches. In <br />addition, there was less common excavation required to construct the boulevards. This resulted <br />in the ability to reduce excavation and sand quantities. This reduction has been included in the <br />enclosed Change Order No. 2. <br /> <br />The West Shadow Lake Area Improvement Project contract with Geislinger and Sons, Inc. and <br />Change Order No. 2 would reduce the contract amount by $139,983.00. <br /> <br />Original Contract Amount $ 4,940,636.57 <br />Change Order No. 1 $ 41,849.00 <br />Change Order No. 2 - $ 139,983.00 <br />Revised Contract $ 4,842,502.57 <br />
