Common symbols, keys and layouts of plans

Symbols are kept as common as possible to all plans to make identifying things simple and recognisable. Layouts too are standardised to help in this also.

Measurements, indicators and sheet types


Brought out “Large Plans” 30 sheets for commercial building, cleared desks and formed a group around them spread out on two desks.

Identify structures, scales, sheet names, builder’s details, North indicators, measurements of rooms, window names and placement, symbols, ceiling heights, fitted cupboards, window details, grid ceiling set up, contour lines and civil works plans,

Discussion lasted approximately 25 minutes just prior to smoko (a time that is usually difficult as students are hungry and restless).

Outcome good initial recognition of elements, symbols, sheet layouts and details, measurements and structures. Maintained focus and interest in-spite of the hunger and caffeine addictions.

Excellent end result..
