CDOT I-25 South Gap Widening Project Moving Forward with CM/GC

10-Nov-2017 to 30-Nov-2017

Over the last year, CDOT has undertaken a Planning and Environmental Linkages (PEL) study to identify a long-term vision for the 34-mile stretch of I-25 south from Monument to C-470. As a result of the study, CDOT identified the 18-mile segment from Monument to Castle Rock, known as "the Gap," as the most urgent and highest priority. With $250 million identified by CDOT and additional local contributions and federal grants looking to fill the funding gap, CDOT is moving forward with a solicitation for Construction Manager General Contractor (CM/GC) Construction Services.

Yesterday, CDOT released a Request for Proposals (RFP) for Project # NHPP 0252-450 (21102) for the I-25 South Gap Project: Monument to Castle Rock. There will be a mandatory Pre-proposal meeting on Thursday November 16, 2017 at 9:30 a.m. at CDOT Region 1, 2000 South Holly St., in the Large Maintenance Conference Room.

The selected contractor will be involved in the design development by providing input into various design elements and constructability. CDOT has retained and contracted with CH2M Hill as the Design Firm of Record. Major stakeholders in the area include CDOT, Douglas County, El Paso County, and FHWA.

CDOT chose the CM/GC delivery method because it provides the quickest opportunity to get a contractor on board, and to potentially get an early package under construction by November 2018. CDOT is still planning to complete a PEL study for the entire 34-mile corridor of I-25 from Monument to C-470. However, that schedule has been extended so that they can focus attention on completing the environmental assessment and design required to begin constructing the 18-mile Gap segment in November 2018.
