Direct peers

• Ballinger: Philadelphia-based AE firm with nationally recognized higher education, healthcare, and science facilities practices. Ballinger competes for RI higher-ed commissions and is BTGA's partner on URI Bliss Hall.
• Payette: Boston-based architecture firm specializing in higher education science/medical facilities and healthcare. Comparable size and New England geography; competes for university research and lab commissions in the same regional market.
• Svigals+Partners: New Haven-based architecture firm specializing in PreK-12 and higher education design. Svigals is a direct competitor on RI/CT K-12 commissions and is BTGA's partner on the $155M Providence Public Schools program.
• Shepley Bulfinch: Boston-based architecture firm with longstanding higher education and library/campus design focus. Closely comparable in scale, geography (New England), and education portfolio — competes for similar RI and MA institutional clients.
• Studio JAED: Mid-Atlantic planning, architecture, and engineering firm with a strong K-12 and higher education portfolio. Studio JAED competes directly for RI school district master planning and is a current BTGA partner on East Greenwich Public Schools work.
• HMFH Architects: Cambridge, MA-based architecture firm with deep higher education and K-12 expertise, particularly in science/lab and vocational programming. HMFH is a direct peer in NE education design and a current BTGA partner on Blackstone Valley biotech lab work.
• S/L/A/M Collaborative (SLAM): Mid-size national AE firm with a dedicated education practice (K-12 and higher education). SLAM is a direct competitor in RI/NE school work and already partners with BTGA on Shea High School — making it both a peer and a current collaborator.

Emerging players

• EwingCole: Philadelphia-based AE firm with growing higher education and science/tech portfolio. Less active in RI today but increasingly pursuing NE university work — making it an emerging competitive threat rather than a direct daily competitor.

Regional players

• LLB Architects: Providence, RI-based architecture firm with a strong higher education and K-12 portfolio across RI and New England. Direct regional competitor with comparable size, geographic focus, and institutional client base.
• DBVW Architects: Providence-based architecture firm with a long-standing education, civic, and institutional practice. Closest local competitor in scale and RI geography; competes for the same public-sector institutional clients as BTGA.
