History
The origins of STV trace back to 1912 in New York City with the establishment of Elwyn E. Seelye & Co., initially concentrating on structural engineering. This early firm, known as Seelye Stevenson Value & Knecht, played a role in notable projects such as the Jefferson Memorial, the parachute jump at the 1939 World's Fair, NASA’s Vehicle Assembly Building at Kennedy Space Center, and Fermilab.
Founded in Pennsylvania in 1945, Sanders & Thomas focused on process and industrial engineering, primarily serving military and industrial sectors. In 1968, Sanders & Thomas joined forces with Voss Engineering Company to create STV, Inc., a holding company designed to acquire firms that eventually formed the current STV Group.
STV broadened its international reach by acquiring Lyon Associates in 1983. The 1990s marked further diversification with the launch of STV Environmental and STV Architects to extend service capabilities. In 1994, STV Construction Services was introduced, alongside the acquisition of STV/Silver & Ziskind, which enhanced proficiency in architecture for criminal justice, education, and healthcare sectors. By 1995, these predecessor entities unified under the name STV Incorporated with its headquarters situated in New York City; however, the parent company remained based in Douglassville, Pennsylvania.
The company’s expansion continued through strategic acquisitions: Ralph Whitehead Associates (RWA) joined in 2006 to reinforce its presence in the Southeastern United States and bridge engineering expertise; DPM was acquired in 2015 to provide owner’s project management throughout all project phases; CP&Y, Inc. became part of STV in 2021, strengthening operations in Texas and the south-central region with enhanced water and highway engineering services; American Engineers, Inc. (AEI) was added in 2023 to better serve Southeastern clients; and MEHTA and Associates, Inc. was incorporated in 2024 to expand infrastructure service offerings within Florida.
