This $67 million design-build capacity and safety improvement project in Jacksonville, Florida involved a complete redesign of the heavily-used interchange between I-95 and JT Butler Boulevard (SR 202) including:
Completed one year ahead of schedule, this $143 million design-build project was located on I-25 through Colorado Springs from Bijou Street to North Academy Blvd. Construction on I-25 widened the highway to three lanes along this 12-mile stretch. Scope included 12 miles of roadway with 18 bridge structures, seven major drainage structures, 250,000 SF of retaining wall, and work over the UPRR and BNSF railroads. SEMA was the only contractor to deliver every additional required element necessitated by the project owner.
This $43 million design-build project involves the design, widening/reconstruction and resurfacing of the Veterans Expressway (SR 589) from south of Gunn Highway to the Sugarwood Plaza. These improvements are to accommodate the future needs for capacity, and to provide operational and safety improvements by widening the existing facility from a divided four-lane to a divided eight-lane section.

The $22 million Peoria Crossing Design-Build Project represents an unprecedented collaboration between the (Owners): City and County of Denver and the City of Aurora, and the additional: Regional Transportation District and Colorado Department of Transportation, to enhance the safety of the traveling public and operational efficiency of Peoria Street. Peoria Crossing is an important connection between Denver and Aurora that was hampered by the at-grade crossing of the Union Pacific railroad tracks. SEMA Construction, Inc. and Parsons Brinckerhoff, Inc. (Project Team) provided a design-build solution involving the construction of a grade-separated structure elevating Peoria Street over the UPRR yard and the future RTD East Rail Line.
Awarded the 2013 ENR Best Project Award
SEMA partnered with The City & County of Denver Denver’s first design-build project. SEMA constructed a new interchange between Stapleton’s Central Park Blvd and I-70. This $30 million project included the design and construction of three bridges, including a six-lane bridge over I-70 and two ramp bridges. The interchange connects CPB and two major interstate highways: I-70 and I-270. More complex than a typical diamond-type interchange, a network of braided ramps was necessary along the north and south of I-70.
This $16.8 million design-build project included the demolition of the existing reservoir and constructing 2 buried reservoirs with adjoining booster pump stations and connecting pipelines for a combined capacity of 9 MG.
This $29 million modified design-build interchange improvement project was located at US 160 and US 550 near Durango, Colorado. The project consisted of completing a four-lane section of US 160 through Farmington Hill, construction of a three-lane interchange, excavation, retaining walls, precast panels, ramps, part of the 550 mainline and four new bridges.
This was an emergency repair project on Highway 67 due to significant flooding in the area.
A major participant for Edward Kraemer Sons, this $11.4 million project is a design-build project which includes four miles of full roadway reconstruction, underground utility infrastructure, 12 new bridge structures and one new 10×8 double barrel box culvert. SEMA’s scope includes removals of all existing pavement surfaces and drainage as well as: 13,500 LF removal of median barrier, installation of 18,000 LF RCP pipe, removal and replacement of 240 LF 44″ sanitary sewer line, 246,000 CY excavation and embankment, and 63,000 TN aggregate base course. SEMA’s scope also includes excavation for temporary and permanent walls, bridge abutments and columns, rip rap placement and detour construction.
This project has been awarded the Gold Safety Award from Liberty Mutual.
SEMA was a major participant on this project widening E-470 from Parker Road to Quincy in Denver, Colorado. SEMA’s portion is $13.3 million.
This project included CM/GC services related to the design and construction of the intersection of Alameda Parkway and Red Rocks Road and the Lower South Lot #2. This project involved multiple stakeholders, had tremendous public attention and visibility, and is located in locally valuable area. In 2015, Red Rocks was designated a National Historic Landmark.
The project scope consisted of two distinct elements including: the reconfiguration of the Alameda Parkway and Trading Post Road intersection and realignment of the road adjacent to Lower South Lot #2. Due to the high-volume use schedule at Red Rocks, all work was coordinated around revenue-generating events without disruption, mandating winter construction to meet strict completion timing in early spring.
This project involved a great deal of environmental stewardship. Excavation generated a multitude of boulders that SEMA partnered with CCD to carefully sort, select, and reposition near the entrances and in other visual areas on-site. Remaining boulders were placed in CCD’s landscape collection for use in future artistic projects.
Based upon the success of the Red Rocks West Alameda and Red Rocks Road/Lower South Parking Lot #2 CM/GC, CCD awarded SEMA a second CM/GC contract to upgrade the stormwater detention system and upper parking lot. The project scope includes: extensive lot reconfiguration to improve traffic management and storm drainage, pavement resurfacing, walkway construction, park user amenities, water main and sewer extension, and construction of a 350,000-gallon underground stormwater retention system with passive water quality improvement structures.

This modified design-build bridge replacement project was located on US 34 east of Estes Park and involved replacing two historic single span bridges over the Upper Big Thompson River, revegetation, minor roadway widening, signing and striping.
This design-build project replaced two superstructures on US 24 and one structure on SH 67. The Cascade Site included bridge replacement on US 24 over Fountain Creek. The Woodland Park Site included box culvert bridge replacement on SH 67 over Loy Gulch. The Florissant Site included bridge replacement on US 24 over Twin Creek.
This emergency project was completed as an immediate emergency response to remediate flood damage to SH 119 due to of Boulder Creek. The project consisted of 20,000 cubic yards of excavation and embankment, over 500 tons of hot mix asphalt patching, more than 4,000 cubic yards of riprap bank fortification, cleaning and repair of culverts, removal of mudslide debris, and other corrective improvements. The project was completed 2 months ahead of schedule allowing CDOT to reopen the road sooner than initially planned and well in advance of other flood remediation projects
SEMA Construction worked with the designer (LJA Engineering) and BNSF to construct this capacity improvement project at BNSF’s Eagle Pass Border Gateway, involved new staging tracks planned to handle growth into Mexico. This project was part of BNSF’s $405 million capital plan in Texas for expansion projects aimed at enhancing capacity and fluidity along the network. This project included a 9,500 ft track, a 9,000 ft track, a 1,000 ft set out track, and a Wye on virgin ground and next to an active rail line.
