CITY COUNCIL AGENDA ITEM 6B STAFF ORIGINATOR: Diane Hankee PE, City Engineer MEETING DATE: February 10, 2020 TOPIC: Consider Resolution No. 20-12, Approving Change Order No. 2 and Accepting the Extension of the Engineering Construction Services Contract. West Shadow Lake Area Improvement Project VOTE REQUIRED: 3/5 INTRODUCTION For the West Shadow Lake Area Improvement Project, staff is requesting council consideration of Change Order No. 2 reducing the contract amount and acceptance of the extension of the engineering construction services contract. BACKGROUND On October 8, 2018, the City Council awarded the bid for the West Shadow Lake Area Improvement Project to Geislinger and Sons, Inc. in the amount of $4.940,636.57. Construction has been ongoing since October of 2018. On March 11, 2019 the City Council approved Change Order No. 1 in the amount of $41,849.00 for the extension of concrete curbing. The 2019 construction season set a record for the number of rainfall events, a total of 39 days. This led to difficult and delayed construction season for the West Shadow Lake Area Improvement Project which required additional maintenance of erosion control measures, pumping of standing water, maintaining the roadway, providing temporary and passable access to residents, and time needed to dry out the site. The contractor met substantial completion 2.5 months late but did not meet the final completion date of November 1. 2019. Construction of the project is almost complete with the final lift of bituminous and boulevard restoration remaining. Due to the inclement weather and additional time spent to maintain the site, the contractor has requested a final completion date extension to June 26, 2020. Changing the final completion date would be approved by Council through Change Order No. 2. During the initial construction of the roadbed. and with further exploratory excavations, the project engineers noted that the soils in the north portion of the project met the road subgrade requirements and the typical section was modified from 24 inches of sand to 18 inches. In addition, there was less common excavation required to construct the boulevards. This resulted in the ability to reduce excavation and sand quantities. This reduction has been included in the enclosed Change Order No. 2.
