BOQ for all Engineering Services (Architectural, Structural & MEP)

Bill Of Quantities – a document that provides specific measured portions of the items of work recognized through the drawings and specs within the request document. Every tender process benefits from the use of a bill of quantities to provide a clear list of the work items for pricing.

The document format of a BOQ can change from project to project, but it will generally include an itemized list of the work required: architectural, structural, mechanical, electrical, plumbing, fire protection, etc. The BOQ also includes the following information:

  • The quantity of work for each list item and the measurement unit.
  • The unit price of each item. The unit price must consider all costs involved: materials, labor, equipment, overhead and the contractor’s profit.
  • The total price of each list item, which is calculated by multiplying the amount of work and the unit price.


The list items in a BOQ are classified by areas like HVAC installations and fire protection systems. All items in each category are added to subtotal prices, and these are added to get the total price of the project. The main advantage of the BOQ is itemizing materials and labor, making these costs easier to manage.

The BOQ should use clear language when describing each work item, since the document is also read by professionals from non-technical fields. If additional information is needed for one of the line items in the BOQ, the construction drawings and technical specifications are available for reference.

Traditionally, BOQs have been calculated by construction estimators, who use the project drawings and technical specifications. This process was first carried out with manual drawings, and it became digital with the development of 2D drafting software.

Many project documents can now be generated automatically with Building Information Modeling (BIM), and this includes the BOQ.  Similarly, for any design modifications after the BOQ is created, it can be updated automatically. BIM software can speed up the process by generating the BOQ automatically, as soon as the design is completed.
