The contractor began removals of the project on September 13, 2019 and since has completed 50% of the work. The directional drilling operation and storm sewer installation along Colleen Avenue is complete. Placement of granular and aggregate base, curb and gutter installation, a storm culvert and reconstruction of the trail section is underway. Project progress Payment No. 1 is provided in Attachment A. During removal of the existing storm sewer in Colleen Avenue, existing draintile was discovered to run the length of the project limits in the granular section of the road along the curb and gutter. Due to the location of the draintile in the trenched area for storm sewer construction, the draintile was not salvageable and had to be replaced. Draintile was also replaced near the additional catch basin on the south side of Colleen Avenue with the remainder salvaged. Change Order No. 2 includes $2,456 for installation of 300 feet draintile at a cost of $7.52 per linear foot and $100 per connection to structure as provided in Attachment B. Page 1 of 2
