Silver Petrucelli + Associates

What Silver Petrucelli + Associates does

Silver Petrucelli + Associates (SP+A) is a privately held, integrated architecture, engineering, and interior design firm headquartered in Hamden, Connecticut, with a secondary office in New London opened in 2018. Founded in 1991 by Bill Silver and Dean Petrucelli, the firm began as a pure architecture practice and expanded over time through the 2006 unification with Sgorbati & Associates (adding in-house M/E/P/FP engineering) and the 2009 establishment of a dedicated interior design department and construction administration division. SP+A now offers four integrated service lines — architecture, mechanical/electrical/plumbing/fire-protection engineering, interior design (including FF&E specification), and construction administration — coordinated through fully integrated BIM/Revit workflows and supported by LEED-informed sustainable design expertise.

The firm serves primarily Connecticut-based public-sector and institutional clients, including K-12 and higher-education facilities, municipalities, state agencies, fire and emergency-services departments, financial institutions, and historic-preservation projects. SP+A holds more than 40 on-call services contracts with entities such as the State of Connecticut Department of Construction Services, the Judicial Branch, the University of Connecticut, the U.S. Navy, and numerous towns and cities, providing recurring responsive design services alongside project-based work that ranges from small renovations to large-scale $100M+ engagements such as the Enfield High School renovation.

Revenue is generated through project-specific professional services fees, with pricing determined by scope, size, and complexity rather than standardized tiers; engagement durations commonly span multiple years, and the firm selectively participates in alternative delivery methods such as design-build through partnerships with general contractors. The firm's go-to-market relies on direct relationships, RFP responses for public work, on-call contract mechanisms, and earned credibility through industry awards (including multi-year Architectural Record Top 300 recognition) and LEED-certified project delivery. Ownership remains concentrated among active principals, with no disclosed external investors or parent company.
