Purpose of Quantity Surveying

To measure and quantify materials needed for a construction project.

Bill of Quantities (BOQ) creation

BOQs are created during the design phase to estimate quantities.

Study Notes

Guidelines for Specification Writing

  • Be specific and not indefinite
  • Be brief, avoid unnecessary words or phrases
  • Give all the necessary facts
  • Avoid repetition
  • Specify in the positive form
  • Use correct grammar
  • Direct rather than suggest
  • Use short rather than long sentences
  • Do not specify both methods and results
  • Do not specify requirements in conflict with each other
  • Do not justify a requirement
  • Avoid sentences that require other than the simplest punctuation

Quantity Surveying

  • Quantity surveying involves measuring or estimating work quantities in different project phases
  • It is used to prepare the project bill of quantities and estimate the project cost
  • Quantity surveying involves calculating the quantity of materials, labor, and equipment needed for the construction work

Purpose of Quantity Surveying

  • Assist the client to have an accurate estimate of work quantity and required budget
  • Assist in the accurate preparation of tenders by providing uniform measurement of quantities

Measurement Rules

  • Mass and thick works are measured in volume (cubic meter)
  • Thin, shallow and surface work are measured in area (meter square) specifying the thickness
  • Long and thin work are measured in length (linear measure, running meter)

Steps of Quantity Surveying

  • There are four clearly defined steps in preparing the Bill of Quantities

Step 1: Taking Off

  • Measure or scale dimensions from drawings and record all dimensions in an easily understood format
  • Couple descriptions from drawings and specifications
  • "Take off" dimensions from drawings and determine the quantity of work to be done
  • Record quantities in a specially prepared format (Take off sheets or Dimension Paper)
