7-Attachment A - Boulder County Trail Repair Plan Set Sample.pdf

This file is a Trail Repair Plan Set Sample prepared by Boulder County Parks and Open Space Department (BCPOS) for the Boulder Canyon Trail Repair Project located in Colorado. The document provides detailed construction plans and specifications for the repair and reconstruction of a damaged segment of the Boulder Canyon Trail and its associated creekside slope protection wall. The project site is positioned downstream of the intersection of Highway 119 and Fourmile Canyon Drive, immediately east of the Highway 119 trail underpass. The trail segment has sustained significant scour damage, creating a substantial void beneath the finished trail surface approaching an existing bridge abutment, while the creekside slope containment structure has been compromised and requires full reconstruction. The scope of work includes protective measures for two existing City of Boulder waterlines that run beneath and through the project area to ensure their integrity during construction activities.

The plan set serves as the technical basis for contractors to develop competitive proposals for this repair project. Key considerations for bidders include addressing the permanent repair of the damaged trail segment, reconstructing the slope protection structure, protecting the dual waterline infrastructure, and ensuring public safety while restoring long-term structural integrity of both the trail and adjacent bridge infrastructure. The sample plan set documentation provides contractors with the necessary technical information to understand site conditions, design requirements, and construction methodologies needed to submit qualified bids for BCPOS consideration.
