These skills will help you measure building works confidently and accurately, which is essential for successful construction projects and cost management.
Preparation of quantities checklist is a critical preliminary step in the take off of building works. It ensures accuracy, completeness, and consistency in quantifying materials and work items, which are fundamental for preparing bills of quantities, cost estimates, and tender documents. For Quantity Surveyors in Kenya, mastering this checklist helps avoid costly errors, supports compliance with local standards such as the PWD Standard Method of Measurement, and facilitates effective communication with contractors and clients.
The first step in preparing a quantities checklist is to fully understand the project scope. This involves reviewing architectural and structural drawings, specifications, and contract documents to identify all elements that require measurement.
Example 1:
A hospital project has architectural drawings specifying a reinforced concrete slab of thickness 150 mm. The Quantity Surveyor needs to confirm the scope of work for the slab.
Given: Slab thickness = 150 mm, slab area = 200 m²$$\text{Volume} = \text{Area} \times \text{Thickness}$$$$= 200 \, m^{2} \times 0.15 \, m$$$$= 30 \, m^{3}$$
Answer: The scope includes 30 m³ of reinforced concrete slab.
Example 2:
A retail building specification includes a provisional sum for landscaping. The Quantity Surveyor must decide whether to include this in the measured works checklist.
Given: Provisional sum = Ksh 500,000
Example 3:
A school project has specified prime cost items for sanitary fittings. The Quantity Surveyor must list these separately.
Given: Prime cost for sanitary fittings = Ksh 1,200,000
The checklist must specify the measurement units and methods for each work item to ensure uniformity and compliance with Kenyan standards.
Example 1:
A bank building requires plastering on walls with an area of 350 m². The measurement unit is square meters.
Given: Area = 350 m²
Example 2:
A county government office requires 120 linear meters of electrical conduit. The measurement unit is linear meter.
Given: Length = 120 m
Example 3:
A hotel project includes concrete foundation excavation with an irregular shape approximated as a trapezoid. The Quantity Surveyor uses volume measurement.
Given: Base 1 = 8 m, Base 2 = 5 m, Height = 10 m, Depth = 1.2 m$$\text{Area} = \frac{(8 + 5)}{2} \times 10 = 65 \, m^{2}$$$$\text{Volume} = 65 \, m^{2} \times 1.2 \, m = 78 \, m^{3}$$
Answer: Excavation volume is 78 m³.
Accuracy in quantities depends on the reliability of the source documents. Verification of drawings and specifications is essential before commencing take off.
Example 1:
A SACCO office drawing shows a wall length of 12 m in the architectural plan but 11.8 m in the structural plan. The Quantity Surveyor must verify which to use.
Given: Architectural wall length = 12 m, Structural wall length = 11.8 m
Example 2:
A university project drawing scale is 1:100. The Quantity Surveyor measures a room length of 5 cm on the drawing.
Given: Drawing length = 5 cm, Scale = 1:100$$\text{Actual length} = 5 \, cm \times 100 = 500 \, cm = 5 \, m$$
Answer: Room length is 5 m.
Example 3:
A retail business project has missing specifications for floor finishes. The Quantity Surveyor must request missing details before measurement.
Given: Missing floor finish specs
Organized documentation supports accuracy and traceability in quantity take off. Proper preparation of measurement sheets is essential.
Example 1:
A cooperative society building project measurement sheet includes:
Example 2:
A KRA office project uses software to record measurements with automatic calculations and version tracking.
Given: Software generates measurement sheets with timestamps and user details.
Answer: Digital documentation improves accuracy and accountability.
Example 3:
A farm building project measurement sheet omits drawing references. The Quantity Surveyor must add these for completeness.
Given: Missing drawing reference
In Quantity Surveying practice in Kenya, accurate take off of building works is critical for preparing bills of quantities and cost estimates. Building works include diverse elements such as framed structures, reinforcement, staircases, doors, windows, and finishes. Each element has unique measurement requirements and calculation methods that must comply with Kenyan standards and construction practices.
Framed structures consist of beams, columns, slabs, and foundations forming the skeleton of a building. Quantity Surveyors must accurately measure the volume or length of these components to estimate materials and costs. The take off involves calculating the dimensions from drawings and converting them to quantities such as cubic meters for concrete or linear meters for beams.
The basic formula for volume of a rectangular beam or column is:
$$ V = L \times B \times H $$
where \(V\) is volume in cubic meters, \(L\) is length, \(B\) is breadth, and \(H\) is height.
Example 1: Calculate the volume of a rectangular beam with length 6 m, breadth 0.3 m, and height 0.5 m.
Given: \(L = 6\, m\), \(B = 0.3\, m\), \(H = 0.5\, m\)
$$ V = L \times B \times H $$
$$ V = 6 \times 0.3 \times 0.5 $$
$$ V = 0.9\, m^3 $$
Answer: 0.9 cubic meters
Example 2: Find the volume of a rectangular column measuring 0.4 m by 0.4 m by 3 m height.
Given: \(L = 3\, m\), \(B = 0.4\, m\), \(H = 0.4\, m\)
$$ V = L \times B \times H $$
$$ V = 3 \times 0.4 \times 0.4 $$
$$ V = 0.48\, m^3 $$
Answer: 0.48 cubic meters
Example 3: A slab measures 8 m by 5 m with a thickness of 0.15 m. Calculate the volume.
Given: \(L = 8\, m\), \(B = 5\, m\), \(H = 0.15\, m\)
$$ V = L \times B \times H $$
$$ V = 8 \times 5 \times 0.15 $$
$$ V = 6\, m^3 $$
Answer: 6 cubic meters
Example 4: Calculate the volume of a beam with a trapezoidal cross-section. The top width is 0.2 m, bottom width 0.4 m, height 0.5 m, length 4 m.
The average breadth \(B_{avg}\) is:
$$ B_{avg} = \frac{0.2 + 0.4}{2} = 0.3\, m $$
Volume:
$$ V = L \times B_{avg} \times H $$
$$ V = 4 \times 0.3 \times 0.5 $$
$$ V = 0.6\, m^3 $$
Answer: 0.6 cubic meters
Example 5: A column with circular cross-section of diameter 0.5 m and height 3 m. Calculate the volume.
Volume of cylinder:
$$ V = \pi \times r^2 \times h $$
Given: \(r = \frac{0.5}{2} = 0.25\, m\), \(h = 3\, m\)
$$ V = 3.142 \times 0.25^2 \times 3 $$
$$ V = 3.142 \times 0.0625 \times 3 $$
$$ V = 0.589\, m^3 $$
Answer: 0.589 cubic meters
Reinforcement take off involves measuring the length and weight of steel bars used in concrete members. Quantity Surveyors calculate the total length of bars by summing individual bar lengths and then convert to weight using the standard mass per unit length of steel bars.
The weight \(W\) of steel reinforcement is calculated by:
$$ W = L \times \rho $$
where \(L\) is total length in meters and \(\rho\) is mass per meter (kg/m) depending on bar diameter.
The mass per meter for steel bars is:
$$ \rho = \frac{d^2}{162} $$
where \(d\) is diameter in mm.
Example 1: Calculate the weight of 100 m of 12 mm diameter steel bars.
Given: \(L = 100\, m\), \(d = 12\, mm\)
Calculate \(\rho\):
$$ \rho = \frac{12^2}{162} = \frac{144}{162} = 0.889\, kg/m $$
Weight:
$$ W = 100 \times 0.889 = 88.9\, kg $$
Answer: 88.9 kilograms
Example 2: Find the total weight of 150 m of 16 mm diameter bars.
Given: \(L = 150\, m\), \(d = 16\, mm\)
$$ \rho = \frac{16^2}{162} = \frac{256}{162} = 1.58\, kg/m $$
$$ W = 150 \times 1.58 = 237\, kg $$
Answer: 237 kilograms
Example 3: A beam requires 8 bars each 6 m long of 20 mm diameter. Calculate total weight.
Given: Number of bars \(n = 8\), Length per bar \(L = 6\, m\), \(d = 20\, mm\)
Total length:

Calculate \(\rho\):
$$ \rho = \frac{20^2}{162} = \frac{400}{162} = 2.47\, kg/m $$
Weight:
$$ W = 48 \times 2.47 = 118.56\, kg $$
Answer: 118.56 kilograms
Example 4: Calculate the weight of 50 m of 10 mm diameter bars.
Given: \(L = 50\, m\), \(d = 10\, mm\)
$$ \rho = \frac{10^2}{162} = \frac{100}{162} = 0.617\, kg/m $$
$$ W = 50 \times 0.617 = 30.85\, kg $$
Answer: 30.85 kilograms
Example 5: A column requires 12 bars each 4.5 m long of 25 mm diameter. Calculate total weight.
Given: \(n = 12\), \(L = 4.5\, m\), \(d = 25\, mm\)

Answer: 208.44 kilograms
Measurement of staircases, podiums, and ramps involves calculating areas and volumes of complex shapes. Quantity Surveyors measure tread and riser dimensions for stairs, surface areas for podiums, and slope lengths for ramps to estimate concrete, finishes, and reinforcement.
Volume of a staircase is often approximated by the product of the floor area it occupies and average thickness.
The slope length \(L_s\) of a ramp is:
$$ L_s = \frac{H}{\sin \theta} $$
where \(H\) is vertical height and \(\theta\) is slope angle.
Example 1: Calculate the volume of concrete for a staircase occupying 3 m by 2 m floor area with an average thickness of 0.2 m.
Given: \(L = 3\, m\), \(B = 2\, m\), \(H = 0.2\, m\)
