10. You are setting up the formwork for a 3 m x 2 m driveway. You are using 100 mm x 50 mm timbers for the formwork side rails and are driving wooden stakes at no more than 1.2 m apart. You will place extra stakes at every joint in the rails and at corners. The timber comes in 3.6 m lengths.

Calculate how many lengths of timber and how many wooden stakes you will need.

Step 1 

Data is being provided, 

Size of driveway = 3 m x 2 m = 3000 mm x 2000 mm 

Size of timber = 100 mm x 50 mm 

Maximum spacing of rails = 1200 mm 

Step 2: Required length of 100 x 50: 

Given Data, 

Length of each piece of timber = 3.6 m 

Required length of 3 m pieces = 3 

Required length of 2 m pieces = 4 

Total length = 3 x 3 + 2 x 4 = 17 m 

Number of timbers = 17/3.6 = 4.7 say = 5 lengths 

Step 3: required number of stakes 

It is proposed to fix stakes at each corner and rail joint. Stakes are fixed for added support to the form work to prevent slipping during concreting. 

Number of stakes = 4 x 3 = 12 stakes

18. What is formwork? Explain its purpose.

The term formwork is being used to provide temporary or the permanent support to the structure or the mould when concrete is being poured in to it. This process is also known as centring or the shuttering.

Formwork is quite important for the concrete in order to harden and give the desired shape to the concrete so that it can gain the strength and the durability. Formwork is commonly used make steel, timbers and other materials.

19. What materials are used in formwork construction? Give 7 examples.

Following are the seven examples of the materials that are used in formwork constructions:

• Timber

• Plywood

• Steel

• Aluminium

• Plastic

• Fabric

• U jack, tie rod and tie nuts

20. Briefly describe the process to erect, strip, clean and stack simple formwork for a small garden shed concrete slab.

21. Place the following steps in the correct order to build formwork for a slab.

• Drive pegs into the ground
• Install the braces
• Height should be marked on pegs
• Nails form board to pegs
• Trim the pegs to heights.

22. What is block-outs?

The term block-outs in concrete is used as the form of EPS which means it is being used in order to create the blank space around the electrical and the water wipes before concrete is being poured around the slab. Once concrete gets harden, polystyrene foam is being removed and will allow the plumbers or the electricians to have an access around the pipes so, that they can easily complete their works.

23. Why are release agents applied to the surface of formwork? Provide 4 reasons.

Following are the four reasons that why it is important to apply the releasing agent to the suface of the formwork:

• Helps the steel formwork from getting corroded.
• It helps in reducing the chances of the leakage of water.
• If formwork is of wooden, concrete absorbs the water and does not let it touch the wooden formwork.
• It provides the good finishing to the surface where concrete is being poured at minimum defects.

24. What is the order of for removing formwork? List 3 steps in the correct order.

Following are the three steps in correct order to remove the formwork:

• It is important to remove the concrete before removing the formwork.
• Shuttering forming is a soffit in order to remove the slab next.
• Shuttering forming soffit of the beams, grinders or the rest of the heavily loaded shuttering need to be removed at last.

25. Outline 4 important factors to consider when storing forms, to ensure they can be reused on another project.

Following are the four important factors that should be considered when storing forms, to ensure they can be reused on another project:

• Make sure that all the materials that are used in the formwork should be closed and packed once the job is over and should kept safe.
• Designing and designating of a small sections of the formwork deck is need to be loaded with the platform for rest of the components.
• Store the various loads on the trolleys in order to minimise the double handling, or they raise the various platform in order to minimise the manual liftings from the level of grounds.
• Adequate amount of storage space is required in order to lay down the areas quite safely so that materials can be stored.

26. What are the specific care requirements for steel formwork components?

In order to maintain the formwork components, oiling is the most important aspects which is required to be done to prevent the formwork from rusting. When the steel is required to be stored they need to be stored properly and away from the humid and airy area.

27. Detail 5 tasks that must be completed before leaving the site at the end of the day?

Following are the 5 tasks that need to be completed before leaving the site at the end of the day are as follow:

• Make sure that it is important to maintain the things by the competent person.
• Always maintain the plant and regularly used equipment-according to the manufacturer’s instruction that is provided to them for maintaining all the safety features.
• There should be proper procedure which will allow the workers in order to report the damaged or any other faulty equipment.
• Always provide the proper tools to for maintaining the person.
• Proper maintenance need to be maintained in order to minimise the risks for the workers who are already working within the same site.

28. Provide 3 control measures to minimise the generation of contaminated stormwater.

Following are the 3 control measures to minimise the generation of contaminated stormwater:

• Always minimise the velocities of the water.
• Reduce the use of the pesticides, herbicides and the fertilizers
• Always minimise the quantity of the storm water which is not uncontaminated.
