What is measurements in construction?
Definition of measurement – Measurement of quantities for construction works. Measurement of quantities for construction works is the transformation of drawn information into descriptions and quantities, undertaken to value, cost, and price construction work.
It is not just about a quantity surveyor producing a bill of quantities for contractors to price during tendering. It is used in both pre-and post-contract work, helping assess the likely cost of the works, and determining what contractors and subcontractors should be paid for work that has been completed.
Pre-contract measurement During the early design stages, the quantity surveyor will measure the dimensions of the building to produce budget estimates, perhaps based on bench-marking against similar buildings. As the design develops, they will measure more detailed approximate quantities for cost planning purposes, ensuring that the design can be achieved within the budget.
- The quantity surveyor then measures the completed working drawings to produce a bill of quantities.
- Contractors tender for the job by pricing the work described in the bill of quantities,
- Post-contract measurement The contractor may use measurement for: Preparing a construction methodology.
- Ordering goods and materials.
Procuring subcontract works. Calculating the effects of any variations. Assessing work done against the construction programme. Making payments to subcontractors. Preparing or assessing valuations of work completed for interim payments. The quantity surveyor may undertake measurement for: Cost control.
Estimating the cost of variations to the work. Calculating the value of nominated subcontractors’ and suppliers’ work. Preparing or assessing interim valuations to pay the contractor for work done. Levels of detail for measured information The degree of detail to which construction work can be measured varies according to its use and the stage in the project.
In the very early design stages, there is not much detail available, so estimates are based on general parameters, such as: Functional unit: For example, cost per school pupil, cost per theatre seat, cost per hospital bed, and so on. Floor area: Cost per sq.
M gross floor area. As the design progresses and more information is known, estimates can become more detailed, such as elemental estimates (for walls, floors, roof, frame, etc.). During the later stages of the design, the work required to construct the building may be measured by: Itemised specification: A detailed cost plan which is broken down into a series of elements.
Initially, the elemental cost plan will simply be the total construction cost for the project divided into elements on a percentage basis. Approximate quantities: A first attempt to measure defined quantities from the drawings (or to take them off from a building information model (BIM)).
- This should be accompanied by a schedule of assumptions made.
- Bills of quantities: The work is measured in detail, usually in accordance with a standard method of measurement.
- Taking off The term ‘taking off’ refers to the process of identifying elements of construction works that can be measured and priced.
Those elements can be measured in number, length, area, volume, weight or time, then collated and structured to produce an un-priced bill of quantities. This process is sometimes referred to as ‘working up’. Standard measurement conventions Always measure gross building area and then deduct items such as exterior walls to find floor space area.
Always measure on the centre line of the material. Calculating girths and centre lines The centre line is halfway between the external and internal girth. Centre line (CL) = (Internal girth + external girth)/2 CL = Internal girth + (No. of corners) x 2(wall width)/2 or CL = External girth – (No. of corners) x 2(wall width)/2 Calculating girths for irregular shaped buildings CL = Internal girth + (No.
of corners) x 2(wall width)/2 Number of external corners = 5 Number of internal corners = 1 External corners – Internal corner = 4 This occurs regardless of shape providing the walls encompass 360°. In the example above, the internal girth was 8.00, and the external girth was 10.00.
Difference = 2.00 m = 4 x 2(wall width)/2 Buildings with an inset Girth = 2(length + width) + 2(depth of inset) = 2(6.00 + 5.00) + 2(2.60) = 27.20 m BIM Increasingly, software packages are available to assist in the preparation of bills of quantities, and building information modelling systems can be used to produce bills of quantities from information already contained within the model.
At Take off Bill, we use the latest Bill of Quantities software when Taking off construction works. This ensures Accuracy, Efficiency and Transparency, our motto here at Take off Bill. We produce Take off’s and Bills of Quantities for all aspects of construction.
Why is measurement important in construction?
4 Powerful Building Measurement Tools for You to Know Building construction is a tough job, especially when you have limited access to cool gadgets. In this case, you have to rely on old manual methods for several measurements, such as distance measurement, airtightness measurement, water leakage measurement, and other calculations. Measurement: The Key to Smooth Building Construction The most important factor of building construction is the accuracy of measurement. Inaccurate and unreliable readings of the parameter can negatively affect the whole process. Accurate measurements can help you smoothly execute your building construction.
Indoor distance measurement
The indoor distance measurement is very important to ensure the timely and safe construction of any building. It is needed from the conceptualization to the completion and the maintenance phase. It would be best if you had accurate building measurement tools to ensure everything is built and placed in the right place.
Outdoor distance measurement
Outdoor distance measurement is equally as important as indoor distance measurement. The outer dimensions being measured should be highly accurate because it is related to the structure of the building – inches of deviation may lead to a result of the collapse.
The height of each floor, the length of the yard, the depth of the swimming pool – everything outside the building is waiting for the precise measure supported by powerful building measurement tools. The airtightness of a structure is vital for a variety of reasons. For one, it helps to maintain the building’s structural integrity, and it also helps to prevent heat loss.
Furthermore, it aids in the improvement of sound insulation. As a result, airtightness measurements are critical in the construction of buildings.
Water leakage measurement
Water leakage can cause contamination and mold to buildings, and sometimes it even affects the foundation of a building, harming the safety of people who lives in it. So, it is essential for the engineers to keep an eye on the water leakage. A helpful building measurement tool will tell you where water leakage happens by displaying the area with lower temperatures.
Heating system condition measurement
Heating systems are used to control the indoor temperature in harsh environmental conditions. The thermal performance measurement is also very important in the construction phase; it should be well controlled to ensure the even heating of the building. How Do Mileseey Products Help Ease the Measurement Now that you’ve learned more about the important measurements in building construction, you’re ready to get started.

What is measurement book and standard measurement book?
Description : Standard Measurement Book (SMB) is used to record the measurements of permanent nature in a building. This recorder is required to be updated every year o the basis of addition/alteration, etc. It is used to facilitate the preparation of repair estimates and contractors bill.
Why are measurement books important?
The measurement Book is a most important record. It is the basis of all accounts of quantities of work done, purchase made and it must contain such a complete record of facts as to be conclusive evidence in court of law.
What are the 3 types of measurement?
Four Types of Variables – Look again at Figure 1.1, You can see there are four different types of measurement scales (nominal, ordinal, interval and ratio). Each of the four scales, respectively, typically provides more information about the variables being measured than those preceding it.

What is a measurement sheet?
Measurement Sheet means the document containing the results of Measurement.
What tool is used to measure a book?
If an item that is being measured fits on a piece of paper, a ruler is probably the best tool to use. Another tool to measure length is a tape measure. They are used to measure many of the distances that are too long for a ruler to measure easily and they are flexible, not rigid.
How many measurement are required to construction?
Hence, the minimum number of measurements required for the construction of a rectangle is 2.Q.
How do you write measurements in construction?
Room sizes – All dimensions are always presented in feet and inches. Even though in Canada we use the metric system, most people understand feet and inches better and the trades that we choose to finish the home typically order materials in Imperial measurements.
- Room dimensions are presented in width by the length.
- For example, a room that has a dimension of 12′ x 16′ means it’s 12 feet wide (from side to side) by 16 feet long (from top to bottom).
- Rooms aren’t always square, so make sure you understand fully how the room feels.
