Architectural Construction Documentation: Points to consider
Architectural Construction Documentation or CD Set is the set of drawings by which a building or its interiors are constructed. It contains accurate information about material, thickness, size, placement, fixing and services. In many countries, the law requires the architect to pay for damages caused due to errors in Architectural Construction Documentation. Here are some points to be taken care of during Architectural Construction Documentation:
The intent of Architectural Construction Documentation is to convey the true size. Dimensioning must take care of practical considerations like:
- Tolerance of measurement by human eye
- Tolerance of manual construction
- Clearances required for machinery
Most of these are taken care by:
- Notes and instructions in case of deviations
- Writing words like ‘equal’, ‘center’ or ‘balance’ instead of a number in the dimension text.
- At times, one may also add to the dimension text, in brackets the word ‘check at site’.
Notes, like the following, become life-savers in case of a dispute or arbitration. Hence, most Architectural Construction Documentation carries these statutory notes on the drawings:
- All dimensions are in millimetres unless otherwise specified
- Do not scale drawing; follow written dimensions only
- Contractor to check dimensions at site before execution and report variance, if any, to this office
- No deviations from this drawing are permitted. Doubts, contradictions and clashes, if any, are to be brought to the notice of this office for resolution
- Refer to the manufacturer
