What Is BoQ In Construction?
A bill of quantities (BOQ) is a document used in tendering and in the construction industry which provides an itemized list of materials, parts, and labor required for a specific job.
It also outlines the terms and conditions of the contract and provides an indication of all work that needs to be completed for accurate pricing by contractors.
BOQs are important for ensuring accurate estimates are given to clients and therefore enable contractors to plan resources appropriately.
They provide an essential overview of the project so that everyone involved understands what is expected and help to avoid costly disputes further down the line.
Who Prepares BOQ In Construction?
A quantity surveyor is the professional responsible for preparing the bill of quantities (BOQ) in the construction industry.
They use their extensive knowledge and experience to assess the quality and quantity of work required to be carried out by the main contractor to complete a project.
The BOQ prepared by a quantity surveyor will also outline details such as costs, necessary materials, labor, and subcontract services. It is an extremely important document in any construction project since it serves as a definitive record of how much each item and service should cost.
Why Is BoQ Required?
A BoQ (Bill of Quantities) is a document that outlines the scope, quantity, and cost breakdown of building works required for a project.
It is critical in evaluating tenders submitted by contractors as it gives them a clear idea of what work needs to be done, and how much to charge and ensures that all tenders are evaluated on an equal footing.
This also helps the client in understanding exactly what they are getting in terms of services and materials – preventing any surprise costs or miscommunications further down the line.
Additionally, BoQs enable more accurate preparation of interim valuations, variations, and final accounts, ensuring clarity throughout the entire project lifecycle.
How Do You Calculate BoQ?
To calculate a Bill of Quantities (BoQ), the total price for each item must be determined by multiplying the amount of work that needs to be done by the unit price of the item.
This includes all costs associated with completing the job including materials, labor, equipment, overhead, and profit.
All bidding contractors must provide their individual unit prices so that an accurate BoQ can be established. Once all unit prices have been obtained, they can then be multiplied by the amounts needed in order to calculate the total price for each list item on the BoQ.
What Is The Difference Between BoQ And BOM?
The key difference between a Bill of Quantities (BOQ) and a Bill of Materials (BOM) is that BOQ provides a brief abstract of the item with details about its major specifications and the overall quantity, while BOM contains more detailed information including individual materials and their quantities required for the particular item.
In other words, BOQ outlines the scope of work related to an item at a macro level, whereas BOM provides details regarding material composition on a micro level.
