About this file
This document is a civil details drawing sheet (C401) from Short Elliott Hendrickson, Inc. (SEH) for the Roaring Fork Transportation Authority (RFTA) Glenwood Maintenance Facility Fuel Tank Relocation project located at 2307 Wulfsohn Rd. in Glenwood Springs, Colorado. The drawing provides technical specifications for concrete and asphalt pavement sections, including detailed diagrams for pavement construction, joint connections, and edge milling. The document includes specific technical requirements for aggregate base course, concrete types, subgrade preparation, and compaction standards, referencing CDOT (Colorado Department of Transportation) standard specifications.
The drawing specifies precise construction requirements, such as using CDOT Class 6 Aggregate Base Course, CDOT Class P concrete for pavement, and CDOT Class B concrete for sidewalks. Earthwork specifications mandate compaction to 98% Standard Proctor Density for prepared subgrade, with specific lift thickness and compaction requirements for different roller types. The pavement sections are based on plans for RFTA GMF Phases 3, 4, 5, & 7, and the contractor is required to submit a jointing plan for engineer review at least 7 days prior to concrete pavement placement. The document is part of bid documents issued on 04/02/2025, with two addenda issued on 4/18/2025 and 4/25/2025.
