We Are Leading Industry of Construction Engineers

We routinely partner with private developers for site work, utilities and civil infrastructure services for commercial, retail, hotel, casino, office and manufacturing clients to maximize value for their investment. Similarly, we specialize in efficient site preparation for master-planned communities, residential buildings, single family homes, golf courses, community centers and education facilities.

Not only does ADAP offer one of the largest civil equipment fleets in the nation, we self-perform the majority of site preparation for our projects, controlling schedule, cost and maintaining overall project quality. As a reliable partner, we locate borrow sources, soils compaction, slope stabilization, rock excavation, manage cut and fill and safely move millions of cubic yards of earth, daily.

Experts and High Quality Works

Powerful equipment is only as effective as its skilled operator. ADAP has been routinely ranked on ENR’s Top Contractors List as the #1 roadway contractor for the last 25 years. As a vertically integrated contractor, we produce high-quality aggregates, asphalt concrete and ready-mixed concrete for internal use and for sale to third parties for paving parking lots, roadway, driveways, gatehouses and more.

For every project we undertake, a formal stormwater pollution prevention plan (SWPPP) is developed that complies with a National Pollutant Discharge Elimination System (NPDES) industrial stormwater permit issued by the Environmental Protection Agency (EPA).

Infrastructure Transportation Services

For nearly a century, we’ve constructed some of the most iconic and complex transportation projects in our nation’s history, developing urban and rural transit programs that connect millions of people, freight and products every day.

From remote single-span to iconic landmarks, bridges are engineering marvels of the modern world. With experience spanning from coast to coast, we offer cable-stayed, tied-arch, beam, truss and suspension bridge construction. Many of our projects are alternative procurement, design-build and P-3 methods, making it easier to fund, innovate and value engineer complex, multi-billion dollar bridge programs.

Reclamation, Pipeline and Mining Infrastructure Solutions

ADAP mining engineers and field personnel have operated in some of the world’s largest mines, side-by-side with mine operators for decades. Proudly upholding relationships with 25 of the world’s largest private mining clients, we provide crushing, leach pads, roads and airfields as well as foundations, reclamation, water management, industrial rail and power services.

Our commitment to mine safety goes far beyond compliance with MSHA regulatory requirements. Mine safety means looking out for each other, immediately correcting unsafe working conditions and keeping safety top-of-mind every second, every minute of every day. At ADAP, our employees understand that safety is not something we do in addition to the work. It’s how we work.

Why Choose Us

More than 50 year experience in industry

ADAP's strength is a combination of quartz and feldspar grains that have been slowly fused together over time. Quartz offers strength, luster and the glue that holds the material together, while feldspar brings color and a resistance to discoloration. Combined, quartz and feldspar are stronger than steel.
