What is the bill of quantity? The materials, labour, and other resources needed to execute a building project are listed in a bill of quantities (BOQ). It is often created by an estimator or quantity surveyor and is used to inform clients and contractors about the size and price of a project.
A bill of quantities often comprises a thorough list of all the materials needed for the project, along with their quantities and costs. This enables contractors to precisely estimate the project’s overall cost and to ensure that their bids contain all essential items.
There are various sections that make up the bill of quantities, including:
- Preliminaries: Before construction can start, there are a number of tasks that must be completed, including clearing the site and doing temporary works.
- General requirements: Included in this part are things like insurance, temporary services, and site security.
- Primary building operations, such as roofing, finishing, and the excavation, foundation, and superstructure, are included in this part.
- Plumbing, HVAC systems, and electrical construction are all included in the mechanical and electrical category.
- External works: This category covers things like site drainage, pavement, and landscaping.
The bill of quantities is a crucial document in the building process since it ensures that everyone involved is aware of the project’s scope and costs. Additionally, it may be used to evaluate quotes from several contractors, monitor project development, and control expenditures all through the building process.
Using a bill of quantities (BOQ) in building projects has a number of benefits, such as:
- Accurate cost estimating is made possible by the BOQ, which offers a thorough description of all the supplies, labour, and other resources needed for the project. This makes it possible for contractors to submit accurate quotes and helps customers set a reasonable budget for the project.
- Fair competition: The BOQ aids in ensuring that contractors submitting bids for the project engage in fair competition. It guarantees that all bidders are making their offers based on the same scope of work by giving a thorough analysis of the criteria.
- Better cost management: During the building phase, the BOQ makes it possible to manage costs more effectively. It is simpler to keep track of expenditures and find areas where prices may be cut by providing a thorough breakdown of the costs.
- Better project planning is made possible by the BOQ’s provision of a clear schedule of the needs. This enables contractors to more efficiently organise their resources and operations, which can assist to reduce delays and guarantee that the project is finished on schedule.
- Reduced chance of disputes: By supplying a thorough explanation of the work’s scope and costs, the BOQ can assist to lower the likelihood of disagreements arising between clients and contractors. This can lessen the possibility of arguments about adjustments or additional work and ensuring that all parties are aware of what is necessary.
