Rapid growth Apex has recently been recognized on the 2026 Hot Firm list and in the top third of the 100 fastest-growing AEC firms, signaling strong market expansion and an opportunity to engage for scalable services such as expansion planning, integration of new practices, and capacity management.

Acquisition activity With multiple acquisitions including Forsgren Associates and Water Science Associates, plus partnerships like Johnson Engineering, Apex is expanding capabilities and geographic reach. This creates openings to offer post-merger integration support, ESG and compliance scaling, and cross-selling of integrated environmental and engineering services.

Full-service potential Apex operates across water, environment, ESG and resiliency, health and safety, compliance, and infrastructure. This breadth provides opportunities to introduce comprehensive program management, digital twin and data analytics, and cloud-based collaboration solutions to streamline multidisciplinary projects.

National footprint Having a presence in all 50 states with a diverse team suggests capacity to handle large-scale, multi-region programs. Sales focus could target national clients requiring consistent standards, rollout of sustainability programs, and uniform QA across sites.

Tech-enabled delivery Utilization of tools like AWS, Google Cloud, ArcGIS, Smartsheet and collaboration platforms indicates openness to tech-enabled project delivery. Potential upsell includes BIM and GIS data integration, enterprise collaboration enhancements, and secure data management solutions for complex environmental projects.
