WSB has acquired Poly, an architecture and engineering firm headquartered in Dothan, Alabama, expanding its municipal, environmental and federal design capabilities while strengthening its presence across the southeastern United States and Gulf Coast.
Financial terms of the transaction were not disclosed. The acquisition adds a firm with more than six decades of experience serving government and commercial clients, including extensive expertise in military facility design and infrastructure engineering.
Founded in 1959, Poly provides architecture, civil and environmental engineering, geological and hydrogeological services, and federal facility design. In addition to its Dothan headquarters, the company operates offices in Birmingham, Alabama, and Shalimar, Florida.
The transaction gives WSB an established presence in several southeastern markets and expands its ability to pursue infrastructure and engineering projects for municipal, environmental and federal customers.
One of Poly’s distinguishing capabilities is its experience designing military training facilities. The company has designed more than 130 military training ranges in the United States and overseas, establishing a specialized track record in federal defense infrastructure.
Military training ranges require expertise across several engineering disciplines, including site planning, civil infrastructure, environmental considerations and the specialized requirements of military operations.
Poly’s experience in this area adds to WSB’s federal design capabilities and could create opportunities to pursue additional projects involving military installations and other government facilities.
The acquisition also expands WSB’s capabilities in environmental engineering and geological services.
Poly’s experience in geology and hydrogeology provides expertise in evaluating subsurface conditions and groundwater systems, which are important considerations for infrastructure development, environmental remediation and long-term land management.
These services can be particularly relevant to municipal and federal clients managing complex infrastructure projects or properties with significant environmental requirements.
Combining those capabilities with WSB’s existing engineering and consulting operations could allow the company to provide a broader range of services throughout the project lifecycle.
For municipal customers, that could include coordinating planning, environmental assessment, engineering design and infrastructure improvements through a more integrated service offering.
The acquisition also provides WSB with a stronger geographic position in the Southeast.
Poly’s offices in Alabama and Florida give WSB additional resources in markets where public infrastructure, federal facilities and environmental engineering projects require local technical expertise.
Establishing a stronger regional presence can be important for engineering firms because infrastructure projects frequently require close coordination with government agencies, local stakeholders, contractors and regulatory authorities.
An established regional team can also bring relationships and an understanding of local permitting requirements, environmental conditions and infrastructure priorities.
Poly’s history in the region provides that foundation while giving its employees access to WSB’s larger national organization.
The companies plan to integrate their services and coordinate how they serve clients throughout 2026 and 2027.
The integration process is expected to bring together their respective technical capabilities and resources while identifying opportunities to serve existing customers across additional engineering disciplines.
For Poly, joining WSB could provide access to a larger engineering and consulting platform, allowing its team to participate in projects requiring additional resources or specialized capabilities.
For WSB, the acquisition adds established offices, experienced professionals and technical expertise that complement its existing infrastructure consulting business.
The transaction is particularly relevant to WSB’s federal services operations.
Federal infrastructure projects can involve complex design requirements, extensive environmental review and coordination among multiple government agencies.
Poly’s experience with military training ranges and federal facilities gives WSB additional specialized capabilities in a market where past project experience and technical qualifications can play important roles in securing new assignments.
The combination could also support projects extending beyond the Southeast, given Poly’s previous work on military facilities in the United States and internationally.
Environmental services represent another potential area of collaboration.
Infrastructure development increasingly requires engineering firms to address environmental conditions alongside traditional design considerations. Projects involving transportation systems, public facilities and military installations may require geological assessments, groundwater evaluations and environmental planning.
Poly’s expertise in these disciplines broadens the services WSB can offer customers seeking coordinated engineering and environmental solutions.
The transaction also reflects WSB’s continued expansion as a national engineering and consulting business.
The company operates from more than 50 offices and has over 1,800 employees nationwide, providing engineering, planning and related consulting services to public- and private-sector customers.
Adding Poly extends that geographic network while broadening the company’s capabilities in several specialized engineering disciplines.
WSB is a portfolio company of GHK Capital Partners, a private investment firm that supports the growth of middle-market businesses.
The Poly acquisition provides WSB with another opportunity to expand its national platform through an established regional engineering business.
The planned integration over 2026 and 2027 will be an important next step as the companies coordinate their operations, technical resources and customer relationships.
Maintaining continuity for existing customers while introducing additional services will be particularly relevant as Poly becomes part of WSB’s broader organization.
With the acquisition completed, WSB gains a stronger position in the southeastern United States, additional expertise in environmental and federal engineering, and a specialized military facility design business with more than 130 completed range design assignments.
The combination expands WSB’s ability to serve municipal and federal customers across a wider geographic area while creating opportunities for Poly’s established regional operations to benefit from the resources and technical capabilities of a larger national engineering platform.
