This project consists of building a new single-storey brick veneer residence of simple construction. It will utilise typical construction techniques and current industry practices.
As the building supervisor of this small residential project you will need to interpret the project documentation to ensure the existing asbestos-clad dwelling on the site is safely and successfully demolished and removed. You must also ensure that the proposed dwelling is constructed safely and according to the correct project documentation.

Work through tasks 1 to 11, referring to the appropriate documents when you have downloaded and/or printed them.

Task 1
Develop a plan to demolish the existing asbestos-clad dwelling in accordance with legislative and planning requirements and utilising safe work practices.

Task 2
Identify the types of loads the building will be subjected to and indicate how they would be transferred through the structural members by marking-up the section drawing.

Task 3
Explain the roles of all the relevant industry professionals you may need to engage and consult. Check all project documentation for errors, omissions and conformance.
Check the BCA requirements for the proposed residential dwelling as if it were to be constructed within the following zones: bushfire, high-wind, earthquake, and alpine. Explain how the construction may need to be modified to conform.
Explain the process within the BCA for certification of new and emerging technologies.

Task 4
Conduct a pre-commencement site inspection. You will need to find a vacant site similar to the one indicated in the working drawings. Use the suggested checklist in the Toolbox to assist you to develop your own. Make sure you provide a sketch of the site.

Task 5
Prepare a footing layout for strip footings and pad footings. You can trace over the floor plan. Note you will need to refer to AS 2870 for footing specifications. Suggest and explain a suitable termite protection system.

Task 6
Prepare a floor joist and bearer layout. You can trace over the floor plan. Note you will need to refer to AS 1684 for member specifications.
Prepare a long span floor joist layout as an alternate option to a conventional floor.

Prepare a concrete slab on ground layout including beam details. Plan the laying procedure of the platform flooring. Prepare a mark-up drawing where you show every individual sheet and the order in which it is to be laid.
Prepare a procedural checklist for the installation of a timber floorboard fitted floor.

Task 7
Prepare a schedule for the entire wall framing members. Note you will need to refer to AS 1684 for member specifications.
Mark-up on the floor plan suitable locations for wall bracing and tie-downs.
Describe and provide sketches of construction details for a variety of external wall claddings. These must include two masonries, two board claddings and two sheet claddings. Clearly include all details relating to sarking, flashing and fixing.

Task 8
Provide a list of all the relevant services to be installed and explain any special provisions required for their installation. Note that a ducted vacuum system is to be installed within the internal timber wall frames.

Task 9
On the roof truss layout plan label each individual type of truss used in the formation of the entire roof system. Also provide sketches of the following types of truss fixing details: joist hanger, triple grip, cyclone tie, and truss grip.
Provide a cross-sectional sketch of a conventional roof system with all the members clearly labelled.
Describe and provide sketches of construction details for a variety of roof claddings. These must include one tile roof and two metal roof sheeting claddings profiles. Clearly include all details relating to sarking, flashing, fixing and minimum pitches.

Task 10
Prepare a window schedule and sketch an acceptable industry installation detail for a timber window clearly indicating the flashing system.

Task 11
Prepare a checklist to ensure the quality of the following systems: footing, floor, wall, and roof. Recommended reading:
• National Construction Code (NCC) Vol 2
• Australian Standards - AS 1684.2: 2010 Residential timber-framed construction Non-cyclonic areas
• AS 2870-2011: Residential slabs and footings

Assessment Task 3: Project
Low Rise Commercial Construction

Instructions
This project will be completed in the student's own time. The participants are to work in groups of 2 to 4 students. The participants will be assessed on their ability to analyse and interpret structural principals according to Australian Standards and Codes. The participants will also be assessed on the communication skills according to the Observation Checklist at the end of this assessment task.

Part 1
• Review the tasks for Parts Two and Three of this project where you will be required to conduct a site visit of low-rise commercial buildings being built and complete the following project.

• From the items listed below, ensure that you will review them during your site visit:
o Profiled steel roof cladding
o Wall cladding
o Roof bracing
o Purlins
o Longitudinal bracing
o Side rails
o Primary steel frame
o End wall girt and rafter
o Window and door header
o Window and door jamb
o Eave strut
o Side wall girt and column

• Discuss (and explain in writing) how you plan on completing the required tasks and inspections (in Parts Two and Three). For example, you may decide to create a checklist of what you will be inspecting and the tasks that you will need to complete during your site visit.

• When providing your answers use the appropriate construction industry terminology

Part Two - Site Visit
In this part you will conduct a site visit of low-rise commercial buildings local to your home and record evidence of having completed each of the tasks in the checklist below. This can be either new construction or existing buildings. In a simulated classroom environment, you can refer to the drawings of a low-rise commercial project provided by the assessor. It is strongly advised that you review the requirements for Part Three now.

In gathering your evidence, you will need to take photos or digital recordings (you may need to obtain permission prior to doing this) demonstrating the requirements have been met.

You must also identify the relevant codes of practice or standards that apply where relevant (e.g. BCA, Vol. no, section, page) and explain the principles of how they have been implemented and adhered to (or not).

Part Three - Apply structural principals
Work through questions 1 to 10, referring to the appropriate documents, resources and the sites that you visited in Part Two of this assessment.

Note: If you have already gathered the required evidence in part two of the assessment, provide details here.

1. Identify the types of loads the building will be subjected to and indicate how they would be transferred through structural members.

2.
a) Explain the roles of all the relevant industry professionals you may need to engage and consult if you were overseeing the construction project.

b) Check the BCA requirements for the proposed commercial dwelling as if it were to be constructed within the following zones: bushfire, high-wind, earthquake, and alpine. Explain here how the construction may need to be modified to confirm to the BCA requirements.

c) Explain the process within the BCA for certification of new and emerging technologies (refer to the NCC Vol. 1 & 2).

3.
a) Prepare a footing layout for strip footings and pad footings. You can trace over the floor plan. Note you will need to refer to AS 2870 for footing specifications.
b) Suggest and explain a suitable termite protection system.
4.
a) Prepare a floor joist and bearer layout. You can trace over the floor plan. Note you will need to refer to AS 1684 for member specifications.
b) State the difference between a long span floor joist layout to a conventional floor.
5. Provide a cross-sectional sketch of conventional wall framing members, including joists, studs, floor joists, ceiling joist and cleats.
6. Provide a cross-sectional sketch of a conventional roofing system with all the members clearly labelled.
