Simpson Gumpertz & Heger
At Simpson Gumpertz & Heger (SGH), we guide superior performance through unparalleled experience.
Our collective knowledge provides us with a unique lens to investigate and explain failures, help codify standards today and innovate the future.
By leveraging our diverse technical expertise, we deliver integrated engineering solutions to address our clients’ most daunting challenges.
Building enclosures
Whether a building is historic and iconic or contemporary and innovative, the individual and integrated performance of roofing, wall systems and fenestration influence the whole building’s performance. The design and repair of building enclosure systems and components must balance performance along with other project considerations, such as aesthetics, constructability and cost.
SGH develops building enclosure solutions for new construction, repair and rehabilitation and preservation projects and applies that experience to investigate failures and performance issues. We complement our work with a portfolio of field and laboratory testing capabilities that help us assess new and existing enclosures.

Performance and code consulting
Building codes are intended to protect the public’s health and safety and are an important aspect of owning buildings and undertaking construction projects. SGH helps clients by evaluating code requirements and developing solutions for structures, building enclosures, fire life safety and accessibility, energy use and other aspects of building performance.
When innovative and complex projects fall beyond the bounds of prescriptive requirements, we conduct engineering evaluations and apply performance-based design approaches to help the project team demonstrate compliance or resilience. When local ordinances or evolving hazards require owners to evaluate their buildings’ existing conditions and vulnerability, SGH conducts assessments, prepares reports for the governing jurisdictions and designs repairs, if necessary.
Applied science and research
Keeping the inside of a building protected from the elements requires expertise to properly design and install the appropriate roofing and waterproofing materials. SGH applies decades of building technology and testing experience to assist with roofing and waterproofing designs, serve as designer of record, provide third-party installation inspections and investigate performance issues.
In our Applied Science & Research Center, SGH can evaluate new and existing roofing and waterproofing materials to understand their composition, predict their performance in the field or determine why they failed.
