Project Description:

RockSol was one of the first teams on-site, working alongside the Colorado Department of Transportation (CDOT) to conduct an initial evaluation and cost estimate of the extent and nature of flooding damage, including areas that were inaccessible by conventional vehicles. RockSol staff mobilized during the flooding event to man roadblocks while flooding continued and assisted CDOT with the initial evaluation, design recommendations, and project mobilization logistics for consultants and contractors as soon as the rain subsided. RockSol mobilized staff within six days to provide field engineering and construction management on behalf of CDOT for SH 7 in Lyons, US 34 in the Big Thompson Canyon, and US 36 in Estes Park. Teams assessed roadway and structures damage, made design recommendations, and prepared cost estimates, which CDOT and the Governor of Colorado used to request and secure Federal Emergency Management Agency (FEMA) funding. We worked hand-in-hand with CDOT to coordinate project logistics from the Incident Command Center (ICC) between the design and construction teams. We also assisted in the ICC with the day-to-day operations of the CDOT finance team, including evaluating the daily detailed damage inspection reports, calculating the actual quantities, categorizing the information on detailed spreadsheets, and reporting the information directly to Federal Highway Administration (FHWA).

The engineering evaluation, construction management, and inspection services conducted by RockSol staff included coordinating extensive manpower, tracking force account work performed by the contractors on a daily basis, and ensuring that CDOT had proper documentation for reimbursement from the Emergency Relief program under FHWA. RockSol collaborated with CDOT, other consultants, and contractors to develop field engineering solutions that met the accelerated schedule. Solutions included the use of concrete flow fill to backfill large erosion holes behind the structural walls, compaction grouting under bridge approach slabs to re-establish grade, and laying thicker asphalt to strengthen roadways at critical points. On SH 7, RockSol worked hand-in-hand with the Contractor to re-establish access to private residences that were evacuated from their homes during the flooding. On US 34, RockSol worked closely with the Bureau of Reclamation and the Contractor to remove a damaged irrigation dam structure and to construct a temporary access road. On US 36, RockSol worked with the Colorado Army National Guard and CDOT on an as needed basis assisting with the reconstruction of the new roadway, including moving the flood rivers back into their original locations. We worked day-and-night alongside CDOT, the contractors, and several other consultants to open all three of these roadways before the December 1st schedule.

Since January 2014, on behalf of the FHWA’s Central Federal Lands Highway Division (CFLHD), RockSol has been conducting inspection for the remaining emergency repairs and for the permanent repairs to US 36. CDOT and CFLHD agreed to combine expertise and resources to enhance the safety and integrity of the roadway against the imminent spring runoff including: stabilizing and moving the highway away from the river by removing a portion of the mountainside via blasting activities, stabilizing the river channel, and reconstructing sections of the highway to repair US 36 on a long-term basis. US 36 is the first mountain corridor receiving permanent repairs due to its critical route into Estes Park for residents, commuters, and tourists. Additionally, the highway will serve as the primary detour route while permanent repairs to SH 7 and US 34 are made.
