This section introduces the plan review considerations associated with floor loading and member performance. Plan reviewers will learn how to identify typical floor loads and verify how these loads are determined within the prescriptive design framework of the IRC. The section also explores how loading affects structural member behavior, including limitations related to span capacity and deflection. Emphasis is placed on understanding deflection limits and verifying that prescriptive span selections shown on plans properly account for both strength and serviceability requirements.
This section focuses on the detailed review of wood floor framing systems constructed from sawn lumber and we will also look at manufactured lumber (TJI Floor Joists). Plan reviewers will learn how to verify floor joist selection, evaluate bracing and blocking requirements, and confirm compliance with notching and connection limitations. The section also covers the review of floor sheathing, including the identification of wood structural panel specifications and proper installation requirements. Emphasis is placed on all critical aspects of floor framing detailing as presented on construction documents.
This section addresses the review of underfloor spaces associated with raised wood-framed floors and the construction of concrete slabs-on-grade. Plan reviewers will learn how to evaluate ventilation, access, and clearance requirements for underfloor spaces. The section also introduces key review considerations for slab-on-grade construction, including material properties and durability requirements. Particular attention is given to weathering and the behavior of cementitious materials, helping reviewers understand how environmental exposure affects long-term concrete performance and how these factors are addressed in construction documents.
Decks present unique structural risks, making careful review essential. This section provides a comprehensive review of deck framing requirements, including deck joists, ledger boards, band joist connections, and deck post framing. Plan reviewers will learn how to evaluate ledger attachment details and verify that deck framing is properly supported and connected. The section also covers connection requirements for lateral load resistance, including ties that provide lateral anchorage between the deck and the primary structure.
This section continues the review of deck construction by focusing on the foundations supporting deck posts and the safety features required along deck perimeters. Plan reviewers will learn how to verify footing and foundation requirements for deck support systems, ensuring that loads are properly transferred to the ground. The section also covers guard rail and guard post requirements, with emphasis on reviewing attachment details and verifying that safety provisions meet IRC requirements.
This section provides a focused, real-world example of floor and deck framing plan review. We will follow the review process as code compliance issues are identified directly from construction documents. The example demonstrates how to review drawings based on IRC provisions and how to document review comments. The construction plans used in this project are provided as downloadable resources which will allow you to work through the review process alongside the lesson and develop practical review skills.
