50 Types of Construction Drawings:
Part 2 (Structural Drawings)
Structural drawings answer the question architectural drawings can't: how does this building actually stand up? These 10 types carry the load path from foundation to roof.
- 16.
Foundation Plan
Shows footings, foundation walls, and slab layout.
Example: a foundation plan for a commercial building on spread footings.
Common mistake: Footing elevations that don't account for the actual site grading, causing field conflicts.
- 17.
Floor Framing Plan
Shows beams, joists, and structural floor layout per level.
Example: a second-floor framing plan for a wood-framed apartment building.
Common mistake: Framing member sizes that don't match the loads shown in the structural calculations.
- 18.
Roof Framing Plan
Shows rafters, trusses, and roof structural members.
Example: a roof framing plan for a gable-roof warehouse.
Common mistake: Truss layouts that conflict with rooftop mechanical unit locations shown on the architectural roof plan.
- 19.
Column Layout / Schedule
Locates and sizes every structural column.
Example: a column schedule for a parking garage.
Common mistake: Column grid lines that shift slightly between architectural and structural drawings.
- 20.
Beam Schedule
Lists beam sizes, materials, and spans.
Example: a steel beam schedule for an office building.
Common mistake: Beam depths that conflict with ceiling height requirements shown on the architectural RCP.
- 21.
Structural Connection Details
Zoomed-in views of how members connect (bolts, welds, plates).
Example: a beam-to-column moment connection detail.
Common mistake: Generic connection details applied everywhere instead of engineered per actual load condition.
- 22.
Rebar / Reinforcement Drawings
Shows reinforcing steel placement in concrete elements.
Example: rebar drawings for a foundation mat slab.
Common mistake: Rebar congestion at intersections that isn't caught until the concrete crew is already on site.
- 23.
Shear Wall Layout
Marks lateral-force-resisting wall locations.
Example: a shear wall plan for a seismic-zone residential project.
Common mistake: Shear wall locations that conflict with architectural door/window openings.
- 24.
Structural Steel Shop Drawings
Fabrication-level drawings for steel members before they're built.
Example: shop drawings for a steel-framed industrial building.
Common mistake: Shop drawings submitted for approval before structural design changes are finalized, causing re-fabrication.
- 25.
Precast Concrete Drawings
Shows precast panel dimensions, connections, and erection sequence.
Example: precast drawings for a parking structure.
Common mistake: Erection sequence not coordinated with crane access and site logistics.
Why structural drawings can't have errors
A structural drawing error can mean a beam undersized for its load, or a connection that doesn't hold under wind pressure. These drawings go through engineering review and stamping for a reason.
