Plan Review Services
In addition to on-site evaluations, our engineers perform comprehensive desktop reviews for new construction, facility additions, site modifications, and risk-improvement projects. Each review verifies compliance with NFPA, FM, ASCE, ICC, and relevant International Code requirements, as well as applicable insurance carrier standards and guidance from the latest best loss prevention research not yet reflected in codes.
We deliver plan review results within five business days, helping projects move forward without delay. Our engineering specialists also provide expert assessments across a wide range of emerging technologies, ensuring your designs remain compliant, resilient, and future-ready.
