Since 1909, Benham has been keeping pace with the evolving civil infrastructure needs in the American southwest, specializing in freeway/highway design, environmental/NEPA assistance, pavement assessment and design, utility relocation , hydraulics/hydrology, traffic and transportation planning and land surveying.
Over the past 10 years, we have completed design and construction support services for interstate/freeway corridor projects, state/US highway and local/municipal projects that included a combination of complex and typical design, rural and urban, two-lane and multi-lane highways featuring new construction, reconstruction, resurfacing, restoration, rehabilitation, and maintenance.
In the last decade, Benham staff has been responsible for more than 200 aviation related projects exceeding 9,000,000 SF of facility space and with a construction value in excess of $2.3 billion for the design of infrastructure projects at home and abroad.
Benham’s airfield experience includes designs for planning, feasibility, new construction, repair and renovation work on runways, airfields, pavements, parking aprons, taxiways, pavement rehabilitation, NAVAIDS and runway / taxiway lighting, utilities, perimeter roads, and access road improvements.
We routinely use the Pavement-Transportation Computer Assisted Structural Engineering (PCASE) software program for design and evaluation of transportation systems, including airfields, roads, and railroads at military and commercial facilities. Determination of pavement life (airfields/roadways), and required upgrades and repairs are critical to our client missions and training operations. Project applications include airfield pavement design, management and modeling; tank trail and hardstand design; pavement condition survey and rehabilitation design for installation roadways; and as a component of life cycle cost analysis of new and rehabilitation designs for roadways and airfield pavements.

Throughout our history, Benham has been an industry leader in the field of transportation infrastructure through projects to design, expand, build, maintain and modernize critical infrastructure locally, nationally and internationally. Our multi-discipline team has the knowledge and experience to guide projects from inception to construction completion. Our services range from studies and assessments to planning, design, and construction management of complex multi-million-dollar programs.
Our roadway design team has extensive experience in designing a wide variety of projects including highways, turnpikes, freeways and interchanges, city streets, county roads and other rural/urban transportation facilities. Our roadway designers and technicians are dedicated to consistently exceed project goals and guidelines to provide our client’s and the citizens they serve a safe and efficient roadway network.
A consistent leader in the design of bridges and other roadway structures, we are experts in design and analysis of new structures, as well as retrofit and rehabilitation designs, inspection and construction for a variety of bridges. In addition, we offer comprehensive bridge inspection services for bridges of all sizes. Our bridge engineers and certified inspectors utilize snoopers, manlifts, bucket trucks, rigging, and rope access to perform condition assessments, evaluations, and inspections and regularly perform scour assessments and load ratings for both on- and off-system bridges.
