5 Construction Drawing Mistakes That Cost Builders Real Money

Most construction budget overruns don't start on site. They start on paper. Five mistakes. All preventable. All expensive. 1. The Title Block Nobody Verified Every permit set has a title block. Project name, address, sheet number, revision date. Most builders never read it. A wrong project address on a title block gets flagged by the permit reviewer. The set comes back.

What it covers:
Floor plans, all levels
Exterior elevations, all four sides
Building sections and wall details

The standard: Clean enough that someone picking it up for the first time can build from it without a phone call.
