CANADIAN HOME BUILDERS’ BC Building Code Plan Checking Assignment 1

This assignment is based on the CANADIAN HOME BUILDERS’ ASSOCIATION OF BC BC Building Code Part 2, focusing on plan checking illustrations. The document includes ten drawings, representing plans submitted for building permits, and identifies areas of non-compliance with the BC Building Code. The assignment analyzes a site plan, elevations (front, right, rear, and left), a foundation plan, main floor plan, second floor plan, and roof truss layouts, assessing their adherence to specific sections of the BC Building Code. Key issues addressed include missing dimensions in the site plan, excessive unprotected openings in the front elevation, beam size, joist accessibility, door requirements, and lintel specifications. The solutions provided highlight areas where the plans do not conform to the code, referencing specific sentences within the BC Building Code. The assignment provides an overview of building plans, helping students understand building codes and their application. Desklib provides past papers and solved assignments for students.
