Notice of Completion (Page A-1) B. Map of the Point Repair Locations (Page B-1) BACKGROUND AND DISCUSSION: Rehabilitation of existing storm drain lines was a component of the Water Quality Flood Protection Program. This Storm Drain Point Repair Project identified several pipes that could not be lined due to local structural failure of the pipes. Seven specific locations needed to be repaired or replaced. The Project was awarded in May 2017 to G.B. Cooke, Inc. The scope of this project consisted of replacing all existing storm drain pipes. During the construction of the 1 project, it was determined that the pipes at three locations could be lined rather than being replaced. The decision was made to line these three pipes instead of replacement, which resulted in some savings. As the construction went on, field changes occurred to provide an acceptable outfall with energy dissipaters in one location, which was not part of the original design. In another location, the existing pipe was between two houses which created additional challenges/costs to replace the pipe. In the last location, we could not get access to the pipe, due to lack of any easement. The property owner did not allow us to access the pipe through his property and, consequently, there was additional cost to finish the work by having to access the pipe from the other end. The additional costs to finish the project exceeded the savings, which is reflected in the executed change orders. The contractor’s work is now finished and has been successfully reviewed for conformance to the project plans and specifications. The total cost of the project is summarized in the following table: CONSTRUCTION COST SUMMARY ITEM AMOUNT Council Authorization $ 2,123,600.00 Construction Costs Construction Contract $ 1,898,730.00 Change Orders $ 119,017.31 Construction Management & Inspection $ 65,773.75 Total Construction Costs $ 2,083,521.06 Construction Savings $ 40,078.94 The project was funded through the Water Quality and Flood Protection Program and was completed within the authorized budget. 2 A-1 A-2 B-1
