I-70 / Tower to Colfax

Geocal assisted the Colorado Department of Transportation (CDOT)..

Geocal assisted the Colorado Department of Transportation (CDOT) in reconstructing the 2 ½ mile segment of Interstate 70 between Tower Road and Colfax Avenue (U.S. 40/287). Work for this project consisted of removing portions of the existing asphalt and replacing it with concrete pavement. Other areas of existing asphalt were overlaid with new concrete pavement, shoulders were widened, and new bridges were constructed over the Union Pacific Railroad and Smith Road.  The project also included numerous retaining walls, drainage improvements and water quality ponds, guardrails, curbs and gutters, signing and striping.

The bridge demolition and reconstruction that was part of this project replaced a bridge that is at capacity. The new bridges included wider shoulder lanes that have improved safety for all motorists. 

During this phase of construction, the on ramp from northbound Tower Road to eastbound I-70 was realigned to improve the flow of traffic and safety at this location. Phasing of this project has allowed traffic flow to continue in the area at reduced capacity without utilizing full long term complete road closures as originally designed. By removing and replacing the bridge in two segments, traffic flow continued on this stretch of road with lane reductions.

Flood Repairs Larimer County

Geocal was one of the first consultants to mobilize staff within a few days..

Geocal was one of the first consultants to mobilize staff within a few days of the historic flooding in 2013, to provide field engineering and construction management on behalf of CDOT for SH 74. We assisted with the day-to-day operations of the CDOT 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).

On the Larimer County Road 29 project, Geocal’s scope of work included roadway design and hydraulic design; incorporated wall architecture into the plans. Geocal conducted a subsurface investigation and provided the recommendations for the bridge foundation and the pavement design parameters for the new roadway and approaches.

Our staff helped quantify the materials going into the emergency repair, documented the efforts of the contractors and provided the necessary support after devastating flooding to re-open both SH74 and Larimer County Rd 29 to the public.

56th Ave. / Quebec to Havana

On the 56th Avenue from Quebec St. to Havana..

On the 56th Avenue from Quebec St. to Havana St. project, Geocal provided geotechinical evaluations for the widening of 56th Avenue as well as reconstruction of two bridges over Chester Avenue and a canal. This project was constructed to improve the flow of traffic on the NE side of Denver between Northfield and towards the airport.

The geotechnical engineering work conducted by Geocal consisted of subsurface investigation, laboratory testing, and geotechnical recommendations for bridge foundations at both bridges and several retaining walls along the corridor, as well as pavement design parameters. Geocal’s staff also performed the materials testing on the project and the materials documentation.

Reconstruction of DIA

Geocal provided inspection/testing for the Enabling phase of the Commuter Rail Access to Terminals at Denver International Airport.  The project included a multi-modal transportation hub with integrated light rail, taxis, bus systems and private vehicles, and helped change the face of the Airport to better serve the Mile High City.
