How to Estimate Building Quantities
One of the first steps in any construction project is to estimate the building quantities. This is also known as quantity surveying or quantity take-off. It involves measuring and calculating the quantities of various items and components that make up the project.
There are three basic steps in quantity surveying:
Identify the scope of work and the items to be measured.
Select the appropriate method of measurement and unit of measurement.
Apply the method of measurement and unit of measurement to each item and record the results.
There are different methods of measurement that can be used depending on the type, size and complexity of the project. Some of the common methods are:
Linear measurement: This is used for measuring items that have length as their main dimension, such as walls, beams, columns, pipes, cables, etc.
Area measurement: This is used for measuring items that have length and width as their main dimensions, such as floors, ceilings, roofs, doors, windows, etc.
Volume measurement: This is used for measuring items that have length, width and height as their main dimensions, such as concrete, earthwork, excavation, fill, etc.
Count measurement: This is used for measuring items that are discrete or indivisible units, such as fixtures, fittings, appliances, furniture, etc.
Weight measurement: This is used for measuring items that have mass as their main dimension, such as steel reinforcement, metalwork, etc.
The unit of measurement is the standard unit that is used to express the quantity of an item. It can be either metric or imperial depending on the preference and practice of the project. Some of the common units of measurement are:
Meter (m), centimeter (cm), millimeter (mm) for linear measurement.
Square meter (m), square centimeter (cm), square millimeter (mm) for area measurement.
Cubic meter (m), cubic centimeter (cm), cubic millimeter (mm) for volume measurement.
Number (No.), each (ea.), pair (pr.) for count measurement.
Kilogram (kg), gram (g), tonne (t) for weight measurement.
How to Use Building Quantities for Cost Planning and Control
Once the building quantities are estimated, they can be used for various purposes related to cost planning and control. Cost planning and control is the process of estimating, allocating, monitoring and managing the costs of a construction project. It helps to ensure that the project is completed within the budget and delivers the expected value.
One of the main uses of building quantities is to prepare cost estimates. Cost estimates are the predictions of the probable costs of a project based on the available information and assumptions. They are used for different purposes and at different stages of the project, such as feasibility study, design development, tendering, contracting, etc.
To prepare a cost estimate, the building quantities are multiplied by the unit rates or prices of the items. The unit rates or prices are the amounts of money that are paid or charged for one unit of an item. They can be obtained from various sources, such as historical data, market research, quotations, bids, etc.
The accuracy of a cost estimate depends on several factors, such as the quality and quantity of information, the level of detail and breakdown, the assumptions and contingencies, the method and technique of estimation, etc. Therefore, it is important to review and revise the cost estimate regularly as the project progresses and more information becomes available.
Another use of building quantities is to perform cost analysis and control. Cost analysis and control is the process of comparing, evaluating and adjusting the actual costs and performance of a project against the planned or estimated costs and performance. It helps to identify and resolve any issues or deviations that may affect the project's success.
To perform cost analysis and control, the building quantities are compared with the actual quantities that are measured or recorded during the execution of the project. The actual quantities may differ from the estimated quantities due to various reasons, such as changes in design, scope, specifications, quality, etc. The differences are then analyzed to determine their causes and impacts on the project's cost and schedule.
If the differences are significant or unfavorable, corrective actions are taken to bring the project back on track. Some of the common corrective actions are: revising the cost estimate, adjusting the budget, negotiating with the contractors or suppliers, implementing changes or variations, improving quality or productivity, etc.
How to Prepare and Present Building Quantities
The final step in dealing with building quantities is to prepare and present them in a clear and consistent manner. This is important for ensuring that the building quantities are understood and used correctly by all parties involved in the project, such as clients, designers, contractors, suppliers, etc.
There are some standard formats and documents that are used for preparing and presenting building quantities. Some of them are:
Bills of quantities: These are documents that list all the items and components of a project along with their descriptions, quantities, units and prices. They are used for tendering, contracting and payment purposes.
Schedules of rates: These are documents that list all the items and components of a project along with their descriptions and unit rates or prices. They are used for estimating and valuing purposes.
Measurement sheets: These are documents that show how each item or component of a project is measured and calculated. They are used for verification and auditing purposes.
Drawings: These are graphical representations that show the layout, dimensions, details and specifications of a project. They are used for reference and clarification purposes.
The best practices for preparing and presenting building quantities include:
Following the relevant standards, codes and guidelines for measurement and documentation.
Using clear and concise language and terminology that is consistent with the project's scope and specifications.
Providing sufficient information and details to avoid ambiguity or confusion.
Using appropriate symbols, abbreviations, units and formats to enhance readability and comprehension.
Organizing and grouping the items and components logically according to their categories, locations or functions.
Checking and verifying the accuracy and completeness of the building quantities before submission or publication.
for effective communication and presentation include:
Using visual aids, such as charts, graphs, tables, diagrams, etc. to illustrate and summarize the building quantities.
Highlighting the key points and findings of the building quantities using headings, subheadings, bullet points, etc.
Explaining the assumptions, limitations and uncertainties of the building quantities using footnotes, comments, disclaimers, etc.
Providing references and sources for the building quantities using citations, links, appendices, etc.
Adapting the style and tone of the building quantities to suit the purpose and audience of the communication or presentation.
