Who in a construction project prepares the BOQ?


The engineering firm in charge of design frequently assumes the responsibility of preparing the Bill of Quantities, which is typically prepared by a cost consultant or quantity surveyor. This way, a neutral party decides the scope and amount of work, and bidding contractors compete on an equal basis. BOQs are frequently created internally by large businesses with internal engineers.

Although the cost consultant and the design firm may be separate businesses, it is more efficient to delegate both responsibilities to the same engineering firm. The cost consultant must first familiarize himself or herself with the project documents when two distinct businesses are involved, necessitating more coordination and communication.


Use of a BOQ in Construction Projects: Benefits


Due to the numerous advantages it offers during the tendering process, using a BOQ is common practice in construction projects:


 Simplicity: The bids submitted by contractors are standardized by a BOQ, making them simpler to compare and analyze. Comparing offers for the same project that include different items is much more difficult.


 Fairness: Contractors compete on an equal basis because a neutral party determines the scope and quantity of work. It would not be fair to hire one of the contractors to create the BOQ because that contractor would gain time and information advantages.


 Speed: When a Bill Of Quantity is available, the bidding contractors can prepare their offers more quickly. Otherwise, each contractor would have to divide the project into sections and figure out how much work each section requires.


 Accuracy: Calculation errors are less likely because the work quantities and measurement units are predetermined.
