About Us

Our Company

In 1995, WSP USA Inspection Services was originally selected by FEMA as the prime contractor for one of two nationwide contracts to inspect homes damaged as a result of a Presidentially declared emergency or natural disaster. The Disaster Housing Inspection Services Program provides emergency grants to qualifying individuals and families that have been adversely impacted by a declared disaster. In performing the work, WSP USA calls on a large network of inspectors that are able to complete inspections within 24 hours of being deployed. These inspectors use handheld computers loaded with government provided software to capture damages to the property. This data is then used to generate a report that allows FEMA to make an award determination, often within hours of the completed application.

During the past 23 years, WSP USA Inspection Services has completed more than 6.6 million inspections for FEMA in connection with disasters such as 2017 hurricanes in Texas, Florida and Puerto Rico, Hurricane Matthew in 2016, the devastating and record- breaking flooding in the 2016 Louisiana flooding, hurricanes Isaac and Sandy in 2012, Irene and Lee in 2011, Gulf Coast hurricanes Katrina, Rita and Wilma in 2005, the four devastating Florida hurricanes in 2004, and the terrorist attacks in New York City on September 11, 2001.

WSP USA Inspection Services is committed to providing quality and timely disaster housing inspections in support of the Federal Emergency Management Agency Individuals and Households Program. Timely services executed with great customer service enable disaster survivors to receive needed assistance to rebuild for a better tomorrow.

"Helping today for a better tomorrow" is what WSP USA Inspection Services is all about.


We work with honesty and integrity at all times. We understand that the future of our business depends upon the trust of our clients and other stakeholders and our reputation for technical expertise and reliable, ethical conduct.

Our Heritage

WSP USA has a 130-year history, with roots in companies founded in the United States, the United Kingdom and Canada. Over the years, dozens of companies based in these countries and others were merged to create the firm known today as WSP USA.

History in the United States

In the United States, the firm’s roots date back to 1885, when William Barclay Parsons founded Parsons Brinckerhoff in New York City. Early projects included the design of the original New York City subway system and the Cape Cod Canal, as well as consulting for hydropower projects in New York State. The firm has worked on many of the major transit systems in the U.S., including San Francisco, Atlanta, Los Angeles, Salt Lake City and Seattle, and has designed countless highways, bridges and tunnels, in addition to consulting on energy, water/wastewater, and community development projects.

Chas H. Sells, Inc. was founded in New York in 1925 and was acquired by WSP in 2007, becoming the transport and infrastructure engineering group of WSP in the U.S., with a specialization in bridge design and engineering.

Other acquisitions integral to WSP’s history in the U.S. include Cantor Seinuk, a structural engineering firm established in 1953, which joined the company in 2000, and Flack + Kurtz, a mechanical, electrical and plumbing engineering business founded in 1969, which was acquired by WSP in 2000. Environment & Energy, an environmental and energy consulting business established in 1986, became part of the company in 2006.

History in the United Kingdom

In the UK, the William Sale Partnership was established in 1969 as a building services consultancy in Surrey. The company entered the London Stock Exchange in 1987 as WSP. The firm was acquired by Montreal-based GENIVAR in 2012.

History in Canada

In Canada, two engineering services firms, G.B.G.M. Ltd and Les Consultants Dupuis Côté, Inc. began operating in Quebec City in 1959. The two firms merged in 1987 to become Groupe-Conseil Solivar Inc. In 1993, Groupe-Conseil Solivar acquired three firms in Montreal and changed its name to GENIVAR. In 2012 GENIVAR acquired WSP, creating a professional services firm with 15,000 employees working in 300 offices worldwide. In January,2014, the company reorganized as WSP Global Inc. and adopted WSP as its brand.

Creating WSP USA

In October 2014, WSP acquired Parsons Brinckerhoff, creating one of the world’s leading engineering professional services firms.
