What BPL Enclosure Engineering does

BPL Enclosure Engineering is a U.S. building enclosure consulting firm that provides engineering, design support, field performance testing, commissioning (BECx), and forensic investigation services for the roofs, walls, waterproofing systems, and facades of complex buildings. The firm originated in 2019 as Bennett & Pless Leicht (BPL), founded by Ed Gazzola and Chris Norris in Atlanta, and rebranded to its current operating name. Its core technical offering rests on three practice areas (Building Enclosure Consulting, Field Performance Testing using ASTM/AAMA-standard protocols such as E1105, E783, D7877, E907, and C1153, and Advanced Enclosure Engineering) supported by specialized modules including facade engineering, air barrier consulting, thermal/hygrothermal modeling (WUFI/THERM), resiliency/hardening, and construction administration.

The firm serves enterprise clients across nine verticals: aviation, healthcare, hospitality, data centers, sports stadiums, civic/government, education, commercial office, and multifamily residential. Named projects include Mercedes-Benz Stadium and EverBank Stadium (NFL), Wellstar Kennestone Hospital, the Georgia State Capitol, and the Truist corporate headquarters. Revenue is generated through project-based professional consulting fees paid by architects, general contractors, developers, and building owners, with no public pricing or subscription model. On January 30, 2026, BPL completed a strategic merger with SEAL Building Enclosure, expanding the combined entity to 14 U.S. offices spanning the Southeast, Texas, Midwest, Mid-Atlantic, Mountain West, and Northeast, with the firm operating as a wholly-owned subsidiary under its existing brand. The company is founder-owned with no disclosed external institutional capital and operates as a sister entity to Bennett & Pless Structural Engineers for integrated structural-facade delivery.

Product overview

BPL Enclosure Engineering is a building enclosure consulting firm that operates as a unified service offering rather than a platform-plus-modules architecture.

Broad incumbents

• Wiss, Janney, Elstner Associates (WJE): WJE is the largest and most established U.S. building enclosure and structural engineering consulting firm, with deep testing, forensic, and design capabilities across every asset class BPL targets. It is the gold-standard competitor BPL most directly chases on marquee projects.
• Morrison Hershfield (a Stantec company): Morrison Hershfield's Building Envelope & Facilities group was acquired by Stantec and now competes as a global, multi-discipline incumbent. It offers envelope consulting at scale comparable to BPL's post-merger footprint but with broader structural, MEP, and infrastructure capabilities.
