About this file
This document is a bid schedule and engineer's cost estimate for the Garden Acres Bridge Replacement project for the City of Longmont, Colorado. The project involves replacing a pedestrian bridge in Garden Acres Park that spans the Oligarchy Ditch, utilizing a salvaged bridge from the Resilient St. Vrain Project. The scope includes bridge demolition, installation of a new bridge with improved decking and rails, utility work, landscape restoration, and maintaining access to an adjacent ditch diversion and pump station. The project requires work on trails, landscaping, and irrigation in the bridge's immediate vicinity, with careful consideration to preserve the ditch channel and detention area capacity.
The engineer's estimates provide three cost scenarios: a base bid of $681,440 for standard bridge replacement, an open trench utility installation option at $718,880, and a bored utility installation option at $801,056. The bid schedule includes base bid items such as mobilization, field engineering, traffic control, bridge removal and installation, utility work, and various restoration activities. Additional bid options focus on sustainability, including 75% project waste recycling and reducing embodied carbon in concrete and steel, with specific references to Colorado Office of the State Architect recommendations for environmental product declarations. The project emphasizes technical precision, environmental considerations, and comprehensive infrastructure replacement.
