If students are not familiar with interpreting blueprints, using scales and general construction terminology they must take Introduction to Residential Construction and Blueprint Reading prior to attending this workshop.

Estimating 1 - Introduction to Residential Construction & Blueprint Reading 

With an emphasis on how products sold every day are used on the job-site, participants will become familiar with residential construction processes, industry terminology, interpreting house plans, and using scales.

Topics covered include:

  • Product applications from foundation through finish

  • Construction definitions and industry terminology

  • Lumber grades and span tables

  • Building material math – board footage, square footage and applying conversion factors

  • Blueprint reading

  • Using architectural and layout scales

  • Estimating decks and railing


Estimating 2 - Residential Material Take-Off

This session will lead attendees through the process of completing a material take-off of residential structures. Emphasis is placed on developing a consistent method for measuring, and applying formulas to produce an efficient take-off. 

Attendees will receive hands-on experience working on an actual set of drawings.  Instruction will include various construction methods and estimating formulas while working on a basic home design with a trussed gable roof.

Topics covered include:

  • Floor framing

  • Wall construction

  • Roof systems


Estimating 3 – Advanced Residential Material Take-Off

The workshop will progress beyond basic house design and focus on some of the more difficult areas of completing framing take-offs.

Topics covered include:

  • Insulation & wallboard

  • Irregular floor and roof layouts

  • Intersecting roof lines with over-framing including valley and jack rafters

  • Multi-pitched roofs

  • Vaulted walls and ceilings

  • Additional time will be included for doors, windows and millwork
