Whether someone is a general contractor or an investor looking to finance building development, it’s helpful to know how to read construction plans, also known as blueprints. While these drawings range from simple to complex, there’s a strong advantage in at least knowing the basics. Here are key facts to know about reading blueprints.

Starting With 2D Drawings Architectural blueprints are designed to be two-dimensional drawings accompanied by detailed explanations. These drawings give contractors visuals with precise dimensions https://medium.com/@AndrewLeigh./the-art-of-reading-blueprints-696890161a2

and relevant information about parts and materials. Blueprints serve as a reference for all construction crew members to operate on the same page. Additional information may identify building codes and installation procedures.

Blueprints are usually scaled-down drawings that state a ratio of the actual size of the final project. In other words, one inch may represent one foot. Every individual blueprint needs a title block, which takes on various forms in terms of shape, size, and placement, depending on the project.

Sheet Sizes & Formatting Blueprints come in various sheet sizes from those that fit in notebooks to large sheets that cover a desk. Creating blueprints digitally through computer-assisted design (CAD) software has become common to speed up time and save money. The question as to what size paper should be used depends on the project since all projects are unique. Many architects are now conscious of saving paper, so they keep sharing of blueprints as digital as possible.

The formatting of construction plans usually includes a cover page, time block, notes, and a revision block to go along with drawing scale and a legend that defines terms and symbols. The cover page should include a drawing that depicts the project. This page also includes the blocks, notes, drawing scale and legend. The industry allows flexibility for each of these features.

Notes should clarify specific directions for designers, engineers and construction workers to understand. Keynotes of deep importance should be distinguished from general notes. The legend must be accurate in describing symbols used in construction plans and should not be assumed. Keep in mind symbols can be interpreted differently by different professionals, even in the same industry. Even when using industry-specific symbols, it’s best to define them in notes so that everyone involved has the same understanding.
