1.Purpose/Background

Boulder County is seeking bids for the Boulder Canyon Trail Wall Repair near the intersection of SH119 and Fourmile Canyon Drive. The Boulder Canyon Trail is supported by a mechanically stabilized earth (MSE) wall. The existing MSE wall is believed to be approximately 25 years old, and the block facing units are in various states of degradation. At the east (downhill) side of the wall, there is a low point in the trail where the wall is in its poorest condition. It is believed that trail drainage over the wall is the primary cause for the advanced deterioration of the wall at this location. Several facing units have completely eroded, exposing the geogrid reinforcing and granular backfill. Portions of the concrete path slab are currently undermined at this location.

The work will mainly consist of replacing the MSE block facing with a reinforced shotcrete facing and concrete work to improve drainage of the trail area.

Potential bidders are encouraged to visit the site located 250 feet west of milepost 39 on CO 119 (Boulder Canyon Drive) near the intersection of Fourmile Canyon Drive.

Due to the emergency nature of this project, the proposer should be prepared to begin construction in Fall of 2023.
