Student Information
Review the important information below in relation to this assessment task.
Instructions

You are required to undertake basic measurements and calculations to determine the size, weight of
materials required in a construction environment. Below are tasks where you are required to measure
and calculate different items. You are then to write the correct answers in the space below. This is an
individual assessment however you may assist each other with holding tape measures.
Note:
You are required to take some photos of yourself undertaking this practical task. This evidence will be
added to the Ready Skills where you teacher/ assessor will be able to mark your assessment.
You can add pictures of your tools and equipment, your finalised completed calculations sheet and a
selfie in your PPE.
Toolbox Talk
1. The class has spoken about, and I understand the ‘risk factors’ involved in this activity
2. If I observe any person working unsafely, I will notify all people present to cease work and will
not continue until controls are put into place and it is safe to proceed.
3. Before commencing this practical task, I agree that if I have not received induction and training in
the correct and safe use of all tools required to complete this task, I will notify my trainer
immediately.
4. I realise when working in the Carpentry practical area I must always wear eye protection and
safety footwear.
5. I have completed all pre safety activities in Ready Skills
I have participated in this JSA and toolbox talk

Activity 1 – Circumference and area of a circle volume and weight of a cylinder.
In this practical activity, you are required to perform some measurements and calculations that involve
the circumference and area of a circle, and the volume and weight of a cylinder.

To complete this activity you will need:
1. A bucket that is roughly cylindrical in shape
2. String
3. Marking pen
4. Tape measure
5. A known volume such as a milk bottle, drink bottle or measuring jug.
Step 1 - Calculate the circumference of a bucket (in m)
Measurement
1. What measuring tool was used?

2. Measure the diameter of the bucket accurate to 1mm:

3. What is this diameter expressed in metres?

Calculation
1. What is the circumference of the bucket (in metres)?
Confirming calculation by measurement
Use a length of string to wrap around the circumference of the bucket, and then measure the string.

2. Was the length of string close (within 5 mm) to the calculated circumference of the bucket? *
Yes
No

Step 2 - Calculate the area of the base of the bucket (in m2)
Calculation
3. What is the radius of the bucket (in mm)?

4. What is the radius of the bucket in metres?

5. Calculate the area of the base of the bucket (in m2)

Step 3 - Calculate the volume of the bucket (in m3)
Measurement
1. Measure a convenient height (example 300 mm) on the bucket. What is the height you
measured?

2. What is the height of the bucket in metres?

Calculation
1. Calculate the volume of the bucket (in m3)

Confirm calculation by measurement
Fill the bucket with water to the height you measured (using a known volume such as a 2-litre milk
container).
2. How much water did it take to reach the marked height?
3. Convert the volume in litres to cubic metres (divide litres by 1000)
4. Was the volume of the bucket you measured using water, close to the volume you calculated?
Yes
No
Step 4 - Calculate the weight of the bucket filled with water
Calculation
Calculate the weight of a bucket filled with water. Use the specific weight of water = 1,000 kg/m3)
This means that 1000 kgs of water would fill 1 m3, or better stated 1 litre of water weighs 1 kilogram. So,
19 litres of water = 19 kgs.




Activity 2 – Measure the internal dimensions of a room & Perform quantity calculations.

Your task: To measure the internal dimensions of a room you are working in to perform some quantity
calculations.

Use the appropriate piece of measuring equipment for this task.

Remember to check that all equipment is in good working order before you begin.
The measurements taken by you will be used to make the following calculations

1. The lineal length of material needed for floor skirting in the room allowing for 10 % wastage.

2. The surface area of the materials needed for floor-covering allowing for 10 % wastage



Measure the internal dimensions of a room to determine quantities needed.
What measurement tool did you use?
Laser distance measuring tool
Ruler
Tape measure
Calculations
Lineal length
Calculate the total perimeter measurement of the skirting in millimetres.

1. Calculate the total perimeter measurement of the skirting in metres.

2. Do a mental calculation of the perimeter and compare it to your calculated answer. Does this
confirm your calculation?
Yes
No
3. Calculate 10 % of the total and enter here (metres).

4. What is the total lineal length of skirting materials needed, including 10 % for wastage?

Area
1. What is the length and width of the room measured?

2. What is the area of the room in square metres?

3. Calculate 10 % of the total and enter here.

4. What is the total amount of floor covering needed, including 10 % for wastage in square metres?


Activity 3 – Measure volume in m3
You are required to measure the volume in m
3
of a footing, slab or rectangular column and calculate the
appropriate quantity ratios for a concrete mix. You must select and use the appropriate piece of
measuring equipment for this task and complete the questions that are set out below

All equipment selected must be in good working order, and you must wear correct PPE throughout the
entire task. You must follow all safety instructions throughout the task. If at any time you are deemed to
be unsafe the assessor will stop your assessment, and this will be counted as your first attempt. You
must actively participate in the toolbox talk prior to beginning the task a be a part of the discussions


The measurements taken by you will be used to make the following calculations:
1. The length, depth, and height of the footing,
2. The amount of concrete needed to complete the job allowing for 10 % wastage
The ratio of cement: sand: aggregate: to be used for this task is 1: 2: 4



Activity 4 -Measure the dimensions of the footing, column, or pier.
Evidence photo - Draw a sketch of the footing that you measured with your measurements shown. You
must also show your working for the calculations.
Check your answers for accuracy before uploading your sketch as part of this assessment.

Height





2. Using the 'Measurement (in metres)' values above, calculate the volume of the item (round up to 1
decimal place)


Ratios
3. There are 7 parts are in the ratio 1:2:4, so what is the value of 1 part in your volume found in step 2?


4. How many cubic metres of CEMENT are required? (Cement has 1 part in the mix)


5. How many cubic metres of SAND are required? (Sand has 2 parts in the mix)


6. How many cubic metres of AGGREGATE are required? (Aggregate has 4 parts in the mix)
