The company plans to move its approximately 175 local employees from its water, buildings, oil and gas, community development and transportation groups on Nov. 25, according to a press release. It currently has Houston offices at 20 East Greenway Plaza, 500 Jefferson St. downtown and 580 Westlake Park Blvd. in the Energy Corridor.

In its new office, Stantec will occupy the entire 26th floor at 910 Louisiana St. The firm’s architecture and interior design arm designed the new 23,000-square-foot office “to reflect the company’s collaborative culture and foster innovative thinking across several business sectors,” per the release. Features include “open, modern, flexible space with collaboration and group work areas, private and quiet work areas, and break rooms.”

“With one integrated group in one location, we’ll be better positioned to foster innovation, resilient-thinking, and inspire new design approaches,” David Irvine, senior vice president and geographic leader for Stantec, said in the release. “It’s important to us to bring together our diverse expertise to deliver the best solutions for our community and clients.”

With more than 45 years in Houston, Stantec has led the design of such projects as State Highway 288, Sterling Aviation Early College High School, Sul Ross Elementary School and several other K-12 schools. The firm also has led projects such as a large-diameter pipeline valve replacement for the city of Houston’s Southwest Pump Station, the design of the Lake Houston Dam rehabilitation, and program management for the Houston Airport System. It’s also serving as the lead designer for the estimated $90 million expansion of the Barry Rose Water Reclamation Facility in Pearland.

Stantec’s services include architecture and interior design; civil, structural and MEP engineering; surveying; land planning and landscape architecture; environmental services, transportation; and water and wastewater engineering.

In September 2016, Houston-based Shell Oil Co. announced it would completely vacate its namesake downtown tower. Shell Oil, the U.S. arm of the Netherlands-based Royal Dutch Shell PLC (NYSE: RDS-A, RDS-B), planned to move its One Shell Plaza employees to the company’s campuses in west Houston. At the time, only employees in Shell’s trading and supply division at 1000 Main were slated to stay downtown. However, the company still lists its U.S. Chemicals division as located at 910 Louisiana.

Since Shell’s 2016 announcement, several tenants have subleased space from the Dutch energy giant. Houston- and New Jersey-based NRG Energy Inc. (NYSE: NRG) subleased a record-breaking 431,037 square feet.
