For the team to be able to construct the park bench you need to be able to "read" the plan. Discuss the following issues with your TAFE teacher:

Remember, if you don't understand the plan, how can you make the project? So if there are any issues you are not sure of, ask.
OCCUPATIONAL HEALTH & SAFETY When undertaking a project like this we need to ensure that our work is carried out safely. Understanding the risks is the first step in accident prevention. It is critical for the team to discuss the following issues:
Refer to the following notes and discuss all these issues with your TAFE teacher.
The Need For Accident Prevention Industrial accidents are a serious community problem. Every year in Australia hundreds of thousands of people are kept away from work for at least one day and almost a million person-weeks are lost. Governments and safety organisations research causes of accidents and actively promote safe working practices. Findings of their research indicates:
These figures are average across all industries. However, occupations such as Plumbing are considered to be high risk where the probability of having an accident is significantly higher than in others. The risk of having an accident is significantly reduced by learning how to work safely. By observing general safety rules you can reduce the likelihood of yourself and others being hurt.
REMEMBER - The person who gets hurt does not always cause the accident. However, accidents are caused by some person failing to act safely, or to correct an unsafe condition.
TAKE SAFETY PRECAUTIONS When using power tools always think about and observe the following safety precautions.
UNIT 2 - GENERAL ELECTRICAL SAFETY Extention Leads Most portable electrical tools must be used in conjunction with extention leads. These leads are susceptible to damage as such the following points must be observed:
Earth leakage faults on-site, are the cause of many serious injuries and deaths each year. That's why it is compulsory on all construction sites to have all power circuits protected at the switchboard/distribution board by approved Earth Leakage Circuit Breakers (Residual Current Device). As from 1990 all new homes are required by law to have a Residual Current Device fitted. In fact all consumers of electricity are being encouraged to fit Residual Current Devices to help safeguard against electrocution. These devices are known by several names in addition to Residual Current Devices (RCD's) including Safety Switches and Earth Leakage Circuit Breakers (ELCB's) but they all essentially perform the same function. RCD's work on an electromagnetic priniciple. When a current (caused by a fault) flows from active or neutral to earth, a tripping signal is established to disconnect the protected circuit. The disconnection occurs rapidly, typically between 10 and 50 milliseconds (msec). The combination of high sensitivity and rapid disconnection means that if a typical earth fault occurs, it will be detected and removed before it can cause damage or injury. On an RCD protected circuit, a person would still receive an electric shock but, as explained above, the duration of the shock would be very unlikely to result in electrocution. An important point to note is that an RCD will not protect against all causes of electrical accidents eg. when a person comes into contact with both active and neutral conductors without passing the current to earth. RCD's should not be regarded as a substitute for care, common sense and regular maintenance.
With this project we will be joining hardwood with bolts and screws, so as to prevent the timber from splitting we need to pre-drill the holes. Following this, to fit the screws, it is far better and easier to use a power drill fitted with a screw bit. As electric drills can be dangerous if in-correctly used, the team needs to be trained so that this tool can be safely used. Discuss the following issues with the TAFE teacher:
This should then be followed by each team member using the drill to:
There are a number of skills that the team needs to develop to construct this project. Discuss these issues with your TAFE teacher and then try them out.
If possible, get some practice at home doing these tasks. Ask for help, most people are only too happy to show you.
PREPARING THE MATERIALS LIST It is very important to prepare an accurate list of our materials as the people we are ordering the materials from have to understand exactly what we want. e.g. From the attached plan (PAGE 1) prepare a list of all materials required to construct a park bench. An example of how this is done for the timber is as follows:
The meaning of this is:
NOTE: We also need to tell the timber merchant what type of timber we are going to use, but as all the timber is the one type, Cypress Pine, we should make a statement before we write the list of timbers stating, "All timber is to be of Cypress Pine". As you prepare the list tick each part of the plan to make sure that you have missed nothing. If you are not sure of a size you can measure it directly from the plan. Remember the plan is to scale (1:10), this means that 10mm(1cm) equals 100mm. NOTE: In the Construction industry all measurements are in millimetres (mm). e.g. Look at the plan and find the tabletop, it measures 900mm. Place your ruler on this and you will find it actually measures 90mm. So whatever you measure just write an extra "0" after it and that will give you the actual size. The fixing devices (screws and bolts) also need to be listed. These can also be estimated off the plan. e.g. We need to fix the table to steel brackets set into the concrete pads where the tables are to be installed. So also two 10mm cup head bolts long enough to pass through each leg and a 6mm steel bracket. Don't forget the nuts and washers.
MATERIALS LIST (TO BE FILLED IN) All timbers are to be "Cypress Pine"
PREPARING THE TOOLS & EQUIPMENT LIST To carry out a project which is not in a workshop with all the equipment available, it is critical that we bring to the construction site everything we need. So we need to prepare a complete list of the required equipment. To do this we need to understand the job and what types of tools are needed to construct it. But there are other issues we need to consider like safety and first aid. First, let us look at the tools we need. (Don't forget we will use some power tools). We are working with timber so we need to:
We now need to consider all the other things that we may need, like:
EQUIPMENT LIST (TO BE FILLED IN)
To build this structure, the team must have the approval of the Local Authority, Moree Plains Shire Council. The purpose of submitting plans of a structure to the Council is to ensure that a basic standard is maintained. This is very important for the community as it helps to preserve health, safety and the environment. What the team needs to do is complete the attached forms. (forms not included in this webpage - see below) A lot of the sections in the forms will not apply to your project so discuss it with your team and if you are not sure, ask for help. Perhaps you could call into the Council and ask there for assistance.
