Crafting Quality Future

Converting Architectural Concepts into Masterworks

Engineering the Future

SAI launched our public works service with assignments for highway and bridge design and bridge inspection in 1964. Since then, we have earned a reputation for our civil engineering expertise.

In 1996, the employees of SAI purchased the company, and SAI became an ESOP corporation. An employee- owned professional consulting engineering firm, SAI has over 130 professionals and support staff with a corporate office in Pittsburgh, Pennsylvania, and three additional offices in Harrisburg, Pennsylvania; Philadelphia, Pennsylvania; and Lake Mary, Florida.

SAI is a focused transportation civil engineering design, inspection, and construction management firm that provides the innovation and manpower that are necessary for our clients to achieve their organizational goals.

SAI's focus is solving complicated infrastructure problems for our clients one project at a time. With the steadily declining revenue sources of state and federal liquid fuels taxes dwindling, transportation continues to be underfunded. Thereby leaving state departments of transportation struggling with increasingly limited budgets and staffs attempting to maintain their facilities with less money every year.
Our staff, including 49 professional engineers, is dedicated to partnering with our clients to provide cost-effective solutions through design flexibility. This is accomplished through managing the design process and taking advantage of techniques and materials that effectively extend the service life of our clients' facilities and minimize future maintenance.

SAI offers client-centric services to all our clients. Whether it’s roadways or bridges, SAI provides value and identifies ways to enhance your project’s efficiency while bringing creative design solutions to your transportation expansion or rehabilitation projects.

In the words of one of our clients:
“SAI and the project team completed the project on schedule and within budget. Communication with all stakeholders was a key to the overall success of this project. They did a commendable job on a complex project.”
