ANS’s engineers work closely with clients to ensure that their transportation projects and facilities are planned, constructed, and operated cost-effectively, safely, and in compliance with all state and federal regulations.
Highways and Roads
From complex urban interchanges to rural road widening projects, ANS has over 40 years of experience serving local, state and federal governments on their highway and road projects. Our services span from initial feasibility studies to final engineering, design and construction management and inspection. ANS understands the pertinent issues that get roadway projects constructed. From initial environmental site permitting to strategies that ensure minimal disruptions to ongoing traffic, our engineers and scientists will work with you to help complete your projects on time and within budget.
ANS’s tunneling experience ranges from cut and cover and soft ground tunnels in the urban environment for utility and transportation projects to deep hard rock tunnels for water storage and conveyance. In addition to traditional tunneling techniques, our work includes selection and design of pipe jacking, TBM, micro-tunneling, and horizontal directional drilling for installation of pipelines beneath highways, bridges, buildings railroads, rivers and wetlands and through congested or contaminated areas. ANS has extensive experience in the site investigation, design, construction observation, instrumentation of tunnels, CSOs, trench-less, micro-tunneling, pipe jacking and other underground construction activities.
ANSworks with owners, contractors and multi-disciplined AE teams to design, engineer and construct a variety of bridge types including suspension, truss and concrete bridges. We provide a suite of consulting services from geotechnical and structural engineering to environmental engineering, instrumentation monitoring, hydraulic and hydrologic and seismic engineering services. ANS has experience in working a variety of project types from Design-Build to specialized, fast-tracked bridge replacement projects that condense design and construction in time frames of a year or less.
ANS structural, geotechnical and environmental engineers and scientists have completed hundreds of parking projects including above and below ground garages, mixed-use parking structures. We provide consulting services through all project phases from initial investigations to design, engineering and rehabilitation.
ANS staff has worked with Class 1 freight rail clients for decades. We provide an integrated suite of environmental and geotechnical services to leading freight rail companies. GEI has completed numerous freight, transit rail and transportation agency projects such as bridge design, tunneling, soil and rock mechanics including slope stabilization, building and other structural foundations, heavy transport piers, EIS, investigation through remediation, NAPL management, property due diligence, data management, asbestos program management, emergency response and other environmental and capital engineering project support.
ANS brings its full breadth of integrated geotechnical and environmental solutions to airports and military infrastructure across the country. We have completed hundreds of projects for airport authorities, airlines and as part of multi-disciplinary AE project teams. Our decades of experience span airport terminal installations and upgrades, taxiways, parking, public transportation, and a host of other commercial and industrial developments.
Ports and Marinas
ANS’s team of professionals has a reputation for providing innovative solutions to support any port, maritime, or freight transportation program. We successfully take projects from the planning phase and through the design, construction, and implementation phases. This includes the regulatory process, conceptual and feasibility analysis at the early stages of a projects life cycle.
