About this file
This document is a 30% Level Engineers Opinion of Probable Construction Cost prepared by Toole Design Group for the Town of Frisco, Colorado, detailing the Granite Street Reconstruction project from Madison Avenue to Summit Boulevard. The comprehensive cost estimate itemizes approximately 40 distinct construction activities, including clearing and grubbing, tree and sidewalk removal, excavation, pavement work, utility modifications, and infrastructure improvements. The project involves installing new concrete and asphalt pavement, plastic pipes, manholes, inlets, sidewalks, curb ramps, brick pavers, lightposts, signage, and landscaping elements across various specified quantities and unit prices.
The total estimated construction cost is $10,229,000, which includes a breakdown of direct item costs ($5,792,461), additional allocations for right-of-way acquisitions and easements (5%), mobilization (10%), traffic maintenance (10%), construction engineering and inspection (7%), erosion control (5%), and a 25% miscellaneous item allowance. The cost estimate incorporates a 4.5% annual escalation factor and is based on 2022 dollars, with unit costs derived from historical data from CDOT and local bid tabulations. The document explicitly notes that the estimate does not include permitting, inspection, construction management, or ongoing maintenance costs, and Toole Design Group provides no guarantees about the accuracy of the final construction expenses.
