A structural key plan is a fundamental drawing within a set of construction documents that provides a high-level overview of the structural layout of a building or project.
According to the provided reference, a structural key plan is primarily a plan to show the structural elements and dimensions. It serves as a guide, indicating the location and basic properties of main structural components.
Key Information Shown
The reference specifies key elements typically included in a structural key plan:
- Beams:
- Location within the structure
- Size (dimensions, e.g., width and depth)
- Slabs:
- Location of the slab areas
- Thickness of the slab
- Direction of spanning (one-way or two-way slabs)
Purpose and Importance
The structural key plan acts as an index and orientation map for the entire set of structural drawings. It helps contractors, engineers, and builders quickly understand the overall structural system and locate specific areas or components detailed in other, more complex drawings. By showing the main elements and their layout, it provides essential context before delving into detailed plans, sections, and schedules.
Think of it as the table of contents or a master plan that points to where different structural systems or elements are located within the building footprint. This foundational drawing ensures clarity and coordination across the project.
