What DrJ Engineering does

DrJ Engineering, LLC is a Madison, Wisconsin-based structural engineering and product certification firm founded in 2011, operating as the engineering arm of the Qualtim family of services. The firm specializes in light-frame construction and truss manufacturing, providing building design for low-rise apartments, single and multi-family residential, and post-frame agricultural and commercial buildings, alongside delegated structural engineering covering proprietary structural design, shear wall and lateral design, truss design, seals and repairs, and truss bracing plans. Inspection services leverage professional engineering licensure in 49 U.S. states and the firm's participation in the development of international codes and design standards.

The company's core technical capability rests on full-scale load path testing that generates proprietary engineered solutions codified into Technical Evaluation Reports (TERs), Design Details (DDs), and DrJ Research Reports (DRRs). In 2015, DrJ achieved ANAB accreditation under ISO/IEC 17065 as a product certification body and describes itself as the only such body that stands behind its certifications with a Professional Engineer seal. Through the Qualtim ecosystem, DrJ's certification branch issues Listings, TER Supplements, Florida Product Approval, and Quality Manual Assistance, while leveraging CBI (Center for Building Innovation) for state-of-the-art testing, including third-party inspection with full structures built on load cells.

DrJ generates revenue through professional services fees for engineering design, inspection, and ANAB-accredited product certification, sold on a quote-based B2B basis to framers, component manufacturers, innovative building product manufacturers (such as the Foam Sheathing Committee and Chemical Technologies Holding Corporation), building officials, and design professionals. Go-to-market is sales-led with direct enterprise engagement and partner-mediated coverage extending services to all 50 U.S. states, Canada, and Puerto Rico. Pricing is not publicly disclosed. The firm has 11-50 employees, holds no external institutional funding, and operates as a privately held LLC under Qualtim.

• IAPMO: IAPMO provides product certification and standards development for plumbing, mechanical, and building systems, including evaluation reports that overlap with DrJ's TER offerings for manufacturers seeking third-party certification.
• ICC Evaluation Service (ICC-ES): ICC-ES is the dominant U.S. building product evaluation body, issuing ESR reports analogous to DrJ's Technical Evaluation Reports. It directly competes for the same building product manufacturer clients seeking code-compliance certification.
• PFS Corporation (PFS TECO): PFS TECO offers building product certification, listing programs, and quality assurance services, competing with DrJ Certification for the same building product manufacturer clients needing code-compliance documentation.

Broad incumbents

• SGS: SGS is one of the world's largest TIC companies, providing testing, inspection, and certification services across construction, industrial, and consumer products. It competes with DrJ on building product certification and structural-related services globally.
• UL Solutions: UL Solutions is a global safety science organization offering testing, inspection, and certification across many industries. It competes broadly with DrJ in building product certification while also serving electrical, electronics, and life safety markets at much larger scale.
• Bureau Veritas: Bureau Veritas is a global TIC incumbent offering building and infrastructure testing, inspection, and certification services. It overlaps with DrJ's engineering and certification offerings for large enterprise clients at significantly larger scale.
• Intertek: Intertek is a global TIC (testing, inspection, certification) incumbent with extensive building and construction product certification capabilities. It competes with DrJ on enterprise-level certification and testing engagements at much larger scale and geographic reach.

Others

• Applied Building Technology Group (ABTG): ABTG is a sibling company within the Qualtim family that provides building technology solutions and technical research. It is thematically related to DrJ through shared ownership and overlapping technical subject matter rather than direct market competition.
• Center for Building Innovation (CBI): CBI is a Qualtim-family structural testing facility that performs full-scale testing, including entire structures on load cells. It is closely related to DrJ as the in-house testing partner for engineering and certification projects, rather than a market competitor.
