Impact of Decision Making on the Credibility of Bill of Quantities (Boq)

Abstract

There is a strong statement of the society that the estimated cost in Bill of Quantities is very less than the actual cost incurred. Further, it means that there is a significant gap between the estimated cost and the actual cost which cannot be accepted. The argument is that the trustfulness of the clients on the BOQ has been understated and the BOQ is prepared for the documentation purposes. Therefore, this study was aimed to find the reasons for the gap arisen between the estimated value of BOQ and the actual value incurred. Data collection method was done through interviews by taking a sample of 50 people who have been involved in preparing and using the BOQ in the construction field. The main dimensions were focused on the role of a quantity surveyor in this regard, types of procurement strategies, defects of cost estimating methods and the parameters of cost estimations. One of the main findings was that the clients have added extra cost to the estimated cost which has not been specified at the point of BOQ preparation. Some of the quantity surveyors believe that the rate adjustments should be more practical by addressing them to the modern complex market. Further, it seems that the accountability of both quantity surveyors and the clients should be enhanced to avoid the misinterpretation of the said statement regarding the BOQ. Then the credibility on the BOQ can be enhanced up to the expected level
