CEC Philadelphia was established in Langhorne, Pennsylvania, in March 2013. The initial focus of services was construction quality assurance (CQA) and solid waste engineering services. Since then, our service offerings have expanded in solid waste (design, permitting, CQA, project management services, and surveying), manufacturing (environmental assessment, remediation, and air quality permitting), power (air quality permitting), and public sector/real estate (civil/site engineering and landscape architecture). In July 2019, CEC acquired Cairone & Kaupp, Inc., a full-service site design firm in the area that merged landscape architecture and civil engineering. Our staff provides a broad spectrum of expertise in civil engineering, environmental engineering and sciences, waste management, and air quality.

CEC is ranked #9 in Pennsylvania and #23 overall on the 2023 ENR Mid-Atlantic Top Design Firms list.

CEC is ranked #12 in Industrial Process on the 2023 ENR Mid-Atlantic Top Design Firms list

CEC is ranked #28 in General Building on the 2023 ENR Mid-Atlantic Top Design Firms list

CEC is ranked #30 in Petroleum on the 2023 ENR Mid-Atlantic Top Design Firms list

In CEC Philadelphia, we focus on an agile working culture. That culture supports each employee’s autonomy, which results in greater developmental opportunities for our staff and clients. Active field work can span 10–11 months out of the year, which is why we nurture independence, creativity, innovation, and cross-discipline participation in the workplace and in the field. Our New Year Luncheon for one of our largest clients and our end-of-year employee gala are always a great time!

Our Culture

We’re dedicated to giving back to the community. Starting in 2018, we pledged to make two monetary donations per year to local charities (ask us about this year’s recipients!). We also participate in various community programs, including Cradles to Crayons, The Salvation Army, and a local soup kitchen.
