Requirements
Commercial Plan Review staff are committed to carrying out the requirements prescribed in the Virginia Uniform Statewide Building Code (USBC). Submittal requirements for plan review are mandated by the building official as empowered by USBC Section 109.

109.1 Submittal of Documents
Construction documents shall be submitted with the application for a permit. The number of sets of such documents to be submitted shall be determined by the locality. Construction documents for one- and two-family dwellings may have floor plans reversed provided an accompanying site plan is approved.

109.3 Engineering Details
When determined necessary by the building official, construction documents shall include adequate detail of the structural, mechanical, plumbing, or electrical components. Adequate detail may include computations, stress diagrams, or other essential technical data. 

When proposed buildings are more than two stories in height, adequate detail may specifically be required to include where floor penetrations will be made for pipes, wires, conduits, and other components of the electrical, mechanical, and plumbing systems and how such floor penetrations will be protected to maintain the required structural integrity, fire-resistance rating, or both. All engineered documents, including relevant computations, shall be sealed by the RDP responsible for the design.
