Workflow in architectural drafting: When starting a coordinated set of building working drawings, which plan is typically produced first to establish room layouts, dimensions, and references for other views?

Introduction / Context:
Drawing set development follows a logical order to ensure consistency. One plan acts as the central reference for dimensions, room names, door swings, and grid/layout control for other disciplines.

Given Data / Assumptions:

• The goal is to establish primary geometry early.
• Subsequent views (elevations, sections, details) reference cut lines from that plan.
• Foundation design also relies on wall and column locations from the plan.

Concept / Approach:

The floor plan is typically created first. It sets the project’s dimensional backbone, from which elevations, sections, reflected ceiling plans, and schedules take alignment and tags. It also coordinates with structural grid and MEP routing.

Step-by-Step Solution:

Verification / Alternative check:

Office standards commonly begin with plan development, followed by vertical views and details; BIM workflows also center around plan levels first.

Why Other Options Are Wrong:

Foundation: Requires wall/column layout derived from the plan.

Elevations/Building section: These are based on plan geometry and callouts; they are developed after plan alignment.

Common Pitfalls:

Attempting elevations first can lead to misalignment with final room sizes and wall locations, causing rework.

Final Answer:

floor plan
