Measurement, Documentation and Project Administration
What you must know
Measurement converts drawings into quantities using a consistent method of measurement. Learn the structure of a bill of quantities: trade or work-section order, preliminary and general items, measured work, and provisional sums. Understand units of measurement - cubic metres for excavation and concrete, square metres for formwork, roofing, and finishes, linear metres for skirting and kerbs, and numbers for fittings - and the rules for describing work so it can be priced. Documentation knowledge includes drawing registers, revision control, transmittals, requests for information, variation orders, site instructions, and progress claims. Project administration covers programming, procurement methods, tender processes, contract types, and the inspection and hold-point regime that links documentation to quality.
Traps
Questions often test whether an item is measured or included elsewhere - for example, whether formwork is measured separately from concrete, or whether a provisional sum is a cost allowance or a fixed price. Watch for unit confusion: a linear metre rate applied to a square metre quantity, or girth versus length in roofing. Another trap is the status of a document: a drawing marked "for construction" carries different authority from one marked "for tender".
Worked example / rule of thumb
A room 5.0 m by 4.0 m with a 2.7 m ceiling: floor finish = 20 m²; wall finish (perimeter 18 m × 2.7 m) = 48.6 m², less openings. Rule of thumb: measure net unless the method says otherwise, and note every deduction. Always record the drawing revision you measured from, because quantities are only valid for the issue they were taken from.
