US 285 Reconstruction: “285 Design Build project team: My compliments to all of you, for your well executed plan! It is a major milestone to have the last old bridge down and in record time too. This team has made a blistering path for others to follow, and are a fine example of innovative design and planning and execution. Great work!”    -Tony Gross, CDOT Project Director

Florida Road Reconstruction: This was a design-build opportunity for the City of Durango. Please see the Design/Build tab for more information on this project.

West Belleview Quincy Ave. to S. Simms St: CEI removed portions of the existing roadway while excavating over 100,000 cubic yards of earthen material. The roadway reconstruction included over 1.5 miles of new roadway and 30000 linear feet of new curb and gutter. The project was under budget and ahead of schedule.

Boulder-Broadway Reconstruction: Project included the removal of existing pavement and the reconstruction of 6,200 LF of combination 4-lane and 5-lane urban arterial roadway to concrete pavement. The corridor included the reconstruction of 5 signalized and 11 un-signalized intersections. Significant public utility work that included 5400 LF of storm sewer, 8000 LF of water line and 1600 LF of sanitary sewer, new traffic signal and street lighting work.

Wewatta St. Phase I: This project located in the heart of downtown Denver consisted of a storm water system installation, paving operations, signalization, and comprehensive landscaping.  The most challenging aspect of this project was coordinating the construction operation in a small construction site all while working in a high traffic zone but was completed a head of schedule in 2009.

The Fitzsimmons Parkway: It consisted over 2 miles of four-lane concrete parkway in Aurora, Colorado.  The work included mass earthwork operations and the re mediation of four landfills along the right-of-way excavating approximately 450,000 tons of soil, detached sidewalks and turn lanes; landscaped median; eight intersections; four signalized intersections. It received: 2006 APWA-Colorado Outstanding Engineering and Construction Management Project and 2006 McGraw-Hill Gold Hat Award Outstanding Heavy Highway Project.

Highway 105 Bridge Replacement: The bridge structure was 200 feet spanning across Plum Creek. The project also had roadway widening and improvements for over 3,000 feet of roadway on Colorado Highway 105 (Perry Park Road) and was planned for significant drainage improvements to Plum Creek as well as wildlife mitigation features. 

Animas River Trail Bridge: This project was a design-build pedestrian bridge and trail located in Durango. Work consisted of a 250 foot steel truss pedestrian bridge, 450 linear feet of waterline, concrete trail, retaining walls, and drainage improvements. It was completed in June 2010.

Clear Creek Canyon Bridge: This project was a bridge replacement for Jefferson County Open Space located in Grant Terry Park, Golden. It features a new small pedestrian bridge and trail which was completed in 6 months time.

Chambers Road (west of Parker): CEI demonstrated a strong finish to this new access way to the oncoming developments along Chambers. This small but well executed bridge is redesigned and built to last for the potential residents that will dwell in the neighborhood beyond.

Great Lawn Open Space Restoration Bridge:. CEI was the prime contractor on the Great Lawn open space improvement project (an extension of the Lowry Redevelopment), which included: over 82,000 C.Y. of earthwork, 118,000 SF of clay liner, 16,000 S.F. of concrete paving, the construction of a double 4x8 box culvert and architectural head wall and a Contech Conspan bridge over Westerly Creek.

Yale-Wabash Bridge: The project consisted of a 180 foot long bridge connecting Yale Avenue on the south bank of Cherry Creek to Wabash Street on the north bank. Along with the bridge, roadway realignments and widening were two other principal features. Significant drainage improvements to Cherry Creek as well as a new sidewalk for a multi-use trail were added on to enhance the site. The entire project was completed in 200 days; from May to November in 2010.

County Road 141 Bridge Replacement: This project was in La Plata County and included a quick completion of excavating, building temporary shoring and water control, forming retaining walls and installing a box culvert that was also featured as a multi-use structure for bridge application.

Wildcat Canyon Bridge and Culvert Replacement: CEI replaced an existing cast-in-place concrete over Wildcat Canyon located on busy CR 141. The project included demolition of the existing bridge, demolition of existing pavement, installation of the culvert with rip rap embankments and reconstruction of the two-lane asphalt roadway above.

Lowery Redevelopment: CEI (Also see the photo on the home page, under services for "water and dam projects"). This project has been a multi-year effort to redevelop the former Lowry U.S. Air Force facility in the cities of Aurora and Denver. To date, CEI has performed significant amount of mass grading, constructed over 20 miles of new roads (including new alleyways, curb/gutter/sidewalks), site drainage and installed miles of water/wastewater utilities.

US 285 Bear Creek Outfall: CEI installed a 10’ x 7’ x 322 LF precast concrete box culvert outfall into Bear Creek on US 285. To protect the FEMA floodplain at the discharge rip rap and permanent erosion control measures were used.

Christine Lake Dam: This dam project included a replacement, a repair, exposing grouted aggregate and designing and implementing a spillway. It was approximately 100,000 cubic yards of dam embankment and lake spillway which was completed in Basalt to improve existing wetland conditions.

Lena Gulch Drainage Improvements: This was improvements within the Jefferson County Fairgrounds to reduce the downstream flooding caused by runoff flowing from Green Mountain. Project construction included a regional detention pond to reduce peak runoff rates downstream of the Fairgrounds.

Stapleton: This has been an on-going site developing project for the Stapleton Airport and facility that had many different components. It included infrastructure improvements, underground utilities, landscaping, sinage, and paving.

Broadstone Lofts: The Broadstone Lofts project, referred to as  2101 Market Lofts, is a mixed-use development in the former 60,000-square-foot “Piggly-Wiggly” warehouse at the corner of 21st and Market streets. The project is a block from Denver's Coors Field. The former warehouse was converted to a 52 apartments, while an eight-story mid-rise was constructed at the site for another 174 units. The mid-rise building includes 6,673 square feet of ground-floor retail space.   The structure also provides two levels of underground parking.

Dakota Jackson Parking Structure: Located at Cherry Creek Trails, this structure consisted of a three-level (podium deck) 300-car parking structure using beams, girders and columns. Post-tensioned deck slabs were used in lieu of precast twin tees. Two elevators provide access to the decks along with two stair towers. Exterior metal cladding finish elements were used to blend the building into the retail and office structures. Two ramps at opposite ends of the structure provide both egress and entrances for vehicles.

Florida Road Reconstruction: Durango, CO. Fostered a 16million dollar total and CEI provided the City of Durango with design-build construction service for the reconstruction of a major urban arterial, Florida Road, which was approximately 2.2 miles of 3-lane roadway with detached sidewalks, roundabout, 16 intersections, MSE retaining walls, sewers and waterlines

Federal Station Transit Improvements: Lakewood, CO. At 6.4million dollars CEI provided the RTD with a design-build service that included a 1,024 parking lot and bus station at the Federal Center, in Lakewood. The project incorporated concrete and asphalt pavement, waterline, signage, landscaping, detention ponds, plaza elements and a small Driver Relief Station storage and washroom.

285 Kippling to Federal:CEI teamed up with Tsiouvaras, Simmons, Hoderness (CEI/TSH) to complete both the design and construction of US 285 Design-Build Project for CDOT. This project consists of: reconstructing approximately 5 miles of Hampden Ave, replacing six existing bridges and other various improvements.
