Key Components of Willis Practice and Procedure for Quantity
To grasp Willis practice and procedure for quantity thoroughly, it’s essential to break
down its major components. These include quantity measurement, documentation, cost
control, and dispute resolution mechanisms.
Quantity Measurement Standards
One of the cornerstones of Willis practice is adherence to established measurement
standards like the Standard Method of Measurement (SMM) or the New Rules of
Measurement (NRM). These frameworks provide clear guidelines on how to quantify
different elements of construction work—be it excavation, concrete work, or finishes.
The process typically involves:
Detailed takeoff of materials from drawings and specifications.
Classification of works into logical units.
Application of uniform rules to ensure consistency.
These standards prevent ambiguity and enable different stakeholders to speak the same
"language" when referring to quantities.
Documentation and Record-Keeping
Accurate documentation is vital in Willis’s approach. Every quantity surveyor is
encouraged to maintain detailed records of measurements, assumptions, and
calculations. This documentation forms the basis for cost estimates, interim valuations,
and final accounts.
Best practices include:
Using standardized forms or digital tools for takeoff and measurement.
Keeping a transparent audit trail for all adjustments.
Regular updating of records to reflect changes in design or scope.
Such meticulous record-keeping helps in defending claims or clarifications during contract
administration.
Cost Control and Budgeting
Willis practice also integrates cost control measures to keep projects within budget. Early-
stage quantity surveying helps in preparing realistic cost plans, which are then monitored
throughout construction.
Key techniques involve:
Comparing estimated quantities with actual site measurements.
Analyzing variances and identifying causes.
Recommending corrective actions to contractors or clients.
By maintaining a continuous feedback loop, quantity surveyors can mitigate financial risks
effectively.
