Below is information on the basics of blueprints and how to read them:

Blueprint Sizes: At ABC, our standard print size is 24" x 36" and we print in-house. Before the advent of computer generated blueprints, home plans were created by hand-drawing the information on vellum. Then the vellum was processed in a similar way as film is developed, which transposes the blue ink print on paper. We use the term "blueprint" to this day even though todays blueprints are printed in black ink on large inkjet plotters. Other size sheets are also available.

Scale: Every blueprint sheet has a key which indicates the scale of that drawing. Usually the scale is 1/4" = 1'. In otherwords, 1/4" on the paper equals 1 foot in "real life". Other typical scales are 3/16" or 1/8", depending on the application and scope of the project.

Site Plan: Site plans are a map of the site and the location of the structure to be built. They typically include set-backs, easements, dimensions, driveways, sidewalks, etc.

Floor Plan: Floor plans provide you with an overhead view of the layout of the home and associated walls, fixtures, cabinetry, stairs, etc. As well, it provides dimensional aspects of the structure.

Electrical Plan: These plans are provided so that your electrician knows the types and locations of outlets, fixtures, lights, fans, etc.

Elevations: Elevations are drawings that show what all four sides of a structure will look like. Some basic dimensions are included in the elevation drawings.

Foundation Plan: This plan shows the location and types of footings, walls, and other structural features needed to support the walls and roof.

Roof Plan: This plan shows the basic design and layout of the roof system, as well as how it fits on the walls below.

Structural Plan: This sheet shows where shear panels and hold downs need to be placed, as well as headers and beams. As well, we provide Floor Framing Plans. This information may be supplied as part of other drawings also.

Cross Sections & Details: This plan shows a cross section, or slice of the home. It provides close up detail of stairs,roof, rafters, floor heights, footing / pad thickness, etc.

General Compliance Notes: This sheet contains information in relation to local code requirements, timber, energy conservation, plumbing and heating, etc.

A full set of home plans typically contains between 7 and 11 sheets.
