Bill of Quantities (BOQ) and Cost Estimation 

In the tendering process, the BOQ document helps to break down the project scope by work items and quantities to the bidding contractors. It ensures that all contractors quote for the same amount of work.

That means, the neutral party determines the scope and quantity of work and the bidding contractors have a fair chance of competition which results in quality deliverables.  

  • Accurate cost planning & continuous cost control protects the owner from financial shocks
  • BOQ is an essential bridge between the design engineer & cost planner. It acts as a tool to track the construction progress and can also be used in project scheduling to forecast the project cost.
  • BOQ can be used to check the deviation between actual work quantities vs the original quantities after the project is completed.
  • An accurate cost plan is of great help during the finalization of contracts
  • Cost planning helps to control costs at every stage of project development

The advantage of BOQ preparations is to itemize material and labor for easily managing the construction project costs. Also, To quote for a project without understanding complete work items is going to be yield incorrect cost estimation, especially in case materials are involved in large quantities.

A good BOQ document must have an easy to read language when describing each work item since the document is also been read by non-technical professionals.
