Abstract:
The Bill of Quantities (BOQ) is a vital document in bothpre contract stage and post contract stage
of any construction project. The BOQ impacts three important aspects of a project namely time, cost
and quality. Therefore, it is crystal clear that if there is any error in BOQ that would directly affect
to the construction project. Since all the stakeholders involved in construction projects are extremely
concerned on time, cost and quality aspects, it is critical that the BOO for the project is error free.
Errors occur during both preparation stage and pricing stage of the BOQ. The BOQ preparation
errors may relate to pricing errors as well as have an impact on the time, cost, and quality’ of the
project. However the study is focused on identifying most common BOQ preparation errors and find
solutions to minimise those errors to support sustainable procurement practice. Initially a semi
structured interview was carried out to identify errors made in preparing BOQs and find reasons for
the errors. Eventually, a questionnaire survey was done to identify the most significant errors that
made and how those errors would affect the project.
The surveys revealed that quantity errors as the most common error during the BOQ preparation
stage which becomes critical based on the type of the procurement method adopted. Employing
experienced person as a reviver was identified as the most preferable solution for minimising
preparation errors. Further it was found that people involved have a greater impact on the BOQ
preparation process and its accuracy.
