Carry out measurements and calculations
ASSESSMENT DETAILS
This unit of competency specifies the skills and knowledge required to undertake basic measurements and calculations to determine task and material requirements in a construction work environment. A person working at this level would be expected to complete tasks assigned to them, under supervision.
Assessment for this unit comprises:
• Measurements and Calculations Worksheet
• Observation.
Assessor checklists, the Measurements and Calculations Worksheet and an Evidence Collection template are provided in this Workbook. Review these documents before you get started so you are clear on what you need to do. Speak to your trainer, assessor or workplace supervisor if you have questions.
TASK REQUIREMENTS
Measurements and Calculations Worksheet
You are to show that you can make the basic calculations and measurements required when working in a construction environment.
You will do this by answering the questions in the Measurements and Calculations Worksheet.
You will need to show your calculations and/or the formulas you use to answer each question. You can use a calculator but you must still write down the method you use to get the correct answer.
Your assessor will provide you with a hard copy of a house floor plan, which you will need to complete some questions.
You must answer all questions correctly to receive a satisfactory outcome for this task.
Observation
You will put your measuring and calculation skills to work during this observation task.
You will need to use measuring and calculation tools to complete your work. Your assessor will ensure you have everything you need.
You will not need to complete any painting or decorating work for this task; however, if you are being co-assessed with other units in this course you will more than likely be applying your skills and knowledge during practical painting and decorating tasks. Your assessor will discuss this with you.
Your activities will require you to perform the following measurements and calculations:
• weight
• volume
• circumference
• percentage
• area
• perimeter
• ratio.
Your assessor will tell you what to measure and what material quantities you need to calculate. For example, you may be asked to:
• measure the walls in a room and calculate how much paint you will need
• measure the walls in a room and calculate how much wallpaper you will need
• measure a variety of shapes and calculate materials requirements and so on.
An Evidence Collection template has been provided in this workbook. You will use this to document the work you do.
You will need to do the following:
• choose the correct measuring tools for the job
• take basic measurements using the right types of measuring tools
• use a ruler or tape measure to make linear measurements that are accurate to 1 mm
• work out material quantities.
Tips for completing this task successfully
• Feel free to draw on the copies of the plans and specs.
• Ensure that you work safely and follow your policies and procedures.
Complete all of these activities.
A room has the following dimensions: L = 3600mm W = 3600mm H = 3000 mm
Calculate the area of one of the long walls in the room. Give your answer in m2.
You have been asked to work out the total surfaceareaof all walls so that paint can be ordered. Assume that there are no windows or doors. Provide your answer in m2.
Write down the formula/method you used.
What is the perimeter of this room in metres? Write down the formula/method you used.
You have been asked to calculate the volume of a tub that has equal sides of 600mm.
Convert the measurements to metres and then calculate the volume of the tub. Write down the formula/method you used.
The diagram below is a slab that needs to be laid so scaffolding can be erected for you to work from safely.
What is the area of the slab? Write down the formula/method you used.
What is the perimeter of the slab? Write down the formula you used.
Convert the length and width of the concrete slab above to millimetres.
Convert the depth of the slab from millimetres to metres.
A room has the following dimensions: L = 4600 mm W = 3400mm H = 3200 mm
You have been asked to work out the areaof one of the long walls so decorative panels can be ordered. Provide your answer in m2.
What is the perimeter of this room in metres?
The decorative panels you are ordering come in packs of four. Each pack covers 1.6 m2. The manufacturer does not split packs. How many packs will you need to order?
A change has been made by the client and they have now decided on wallpaper for the feature wall instead of decorative panels.
Each roll of wallpaper is 1100 mm by 10 m. There is no pattern matching required.
There will be no cornice in the room and the skirting will be 100 mm.
Calculate the drop.
How many drops will you need for the feature wall?
How many metres of wallpaper will you need for the feature wall?
Add 10% for wastage.
How many rolls of wallpaper will you need (remember that there is no pattern matching)?
You need to cut a hole in the wallpaper to fit around a wall sconce. The hole is 370mm in diameter.
Note: π = 3.1416
What is the radius of this hole? Write down the formula/method you used.
What is the circumference of the hole? Write down the formula/method you used.
What is the area of the hole in mm2? Write down the formula/method you used.
What is the perimeter of this decking? Write down your calculations.
Convert the perimeter into metres.
What is the area of the decking in mm? Write down your calculations.
Convert the area into metres.
What is the area of this triangle? Write down the formula you used.
What is the area of this triangle? Write down the formula you used.
What is the volume of this triangular prism? Write down the formula you used.
What is the area of this trapezium? Write down the formula you used.
What is the volume of this trapezium prism? Write down the formula you used.
What is the volume of a water tank with the following dimensions:
Height = 200cm Diameter = 100cm
Convert your answer to litres.
When taking measurements and calculations, you will use a range of equipment. For each of the following, list at least two advantages and two limitations.
Your assessor will provide you with a hard copy printout of a house floor plan.
Your job is to take some measurements so materials can be ordered. Make sure you have the right measuring and calculating equipment.
Fill out the table below and show your workings. The plans are scaled at 1:100. You will need to convert your L W H measurements from metres to millimetres.
