“RWC provided Structural Engineering services recently on the $45 million Concourse C West Expansion at Denver International Airport. This project was designed and construction completed in 2 years, with early crucial bid packages provided by RWC enabling the short schedule to be met and the project completed on budget.


RWC also teamed with WSA on other major projects such as the original Denver International Airport (DIA) Design of Concourse B Tenant Improvements and Construction Administration, Aircraft Parts and Distribution Center, Mail Handling Facility, and Domestic Commuter Facility. These projects represented over $280 million in construction costs and were all completed simultaneously. Since then RWC has assisted us with four DIA On-Call contracts spanning over 14 years and numerous other Aviation projects at DIA.”



Denver International Airport

Concourses A, B, C

The three concourses in conjunction with the terminal were conceived to meet a number of objectives: serve existing passenger traffic demands, meet increasing passenger needs for decades to come, integrate the latest airport technologies, and provide passengers ease of access in a dramatic setting. In the concourses, anticipatory structural engineering allowed for moving walkways, baggage, conveyors and gate configurations. Originally designed to be identical, each of the three concourses were individualized: different widths, depths, levels and lengths – the largest being nearly one mile long; all engineered to be readily expanded in the future. The key engineering innovation in the concourse cores was the introduction of imaginative trusses that carry five levels of transfer columns and beams. Christened “Hero Trusses” because they “do everything you can ask of a structure,” each truss supports 250 tons of load allowing for grandiose, column-free, clerestory atrium spaces – 18,000 square feet in area and 105 feet high –topped off with a glass roof. Special pin and knuckle joints were invented to connect “Hero Trusses” with cantilevered columns and to dissipate torque from differential loading conditions. The aggressive timetable required that the structures be designed before major tenants committed to the project and added their specific needs. Flexibility introduced in the structural design process allowed for major, cost-saving changes in the terminal roof design and for the introduction of new fully automated baggage handling systems in all buildings after basic designs were completed.

Denver International Airport Tenant Modifications

Separate from the structural design of the Concourse A, B, and C bare buildings, RWC has provided the structural design on several major modifications and completion projects for the City, airlines, and tenants. Examples of this work include: International airside modification and addition for Concourse A, including pedestrian bridge module, Regional commuter gate additions on Concourse A and B, Postal service additions on Concourse A and B, as well as numerous tenant and concession reviews, additions and modifications.

Denver International Airport On-Call Technical Services

Denver, Colorado

Since the completion of DIA, RWC has continued to provide engineering and design services for the City. This work has included the widening of Concourse B during the original construction, loading reviews, base buildings modifications and additions.

Buckley Airport

Buckley Airport

Buckley Corrosion Control Facility
Buckley Air Force Base     

This project included airfield pavement design for tricycle gear aircraft, standard TM5-824-3/AFM88-6. A design for jet aircraft was furnished to support 42 lb. Capacity wheel ratings on 18” and 12” asphalt thicknesses. Understanding of aircraft clearances and turning radii was used to size and locate hanger doors and hardware.






Stapleton Concourse B

Stapleton Concourse B

Stapleton International Airport
Denver, Colorado

RWC provided structural engineering services for a massive addition and renovation of the existing concourse. Concourse B was widened from 82’ to 112’, lengthened by 80’ and the roof was raised from approximately 22’ to 49’ above the ramp level (the level of the concrete apron around the building). Where possible, parts of the 20 year old rigid concrete frames were incorporated. Steel was used for the superstructure and deep-drilled concrete piers were used for the foundation.





Scottsbluff Airport
Scottsbluff, Arizona

RWC was responsible for the structural and civil design of pavements, aprons and the terminal at Scottsbluff Airport.


Kimball Airport
Kimball, Nebraska

RWC was responsible for structural and civil design of pavements, aprons and the airport fire stations.


North Platte Airport
North Platte, Nebraska

RWC was responsible for structural design of pavements, aprons and the airport fire stations.

This thing alone can be a deal breaking for some, but hey, as long as the other person doesn’t know you’ve read the message, you’re golden
