UO Construction 1
This activity contributes to 40% of the total course grade.
The aim of this assessment is designed to provide students with an appreciation and record of the wall and roof
design and erection processes involved in constructing a typical domestic-scale wall and roof. The exercise will be
representative of the actual work undertaken on site – although to a much smaller scale of course.
It is beneficial to familiarise yourself with the relationship between the activity and the course objectives.
• CO1. Outline the various trends in development of modern housing.
• CO2. Identify the current work practices of residential building companies.
• CO3. Identify the principal components of single storey domestic construction.
• CO4. Demonstrate an understanding of the building regulations and standards.
• CO5. Explain the sequencing and coordination of building elements.

You will work individually on this project, to construct a wall and roof model Part A: Construction of a wall and roof
model. You will also be responsible to maintain and document a work schedule and log all critical facets of the
project processes, as you build the model (Part B: Work schedule).
An Assessment 1 Part A & B Discussion Forum will be optionally available to use for you to participate in discussion
with your cohort. You will be able to use this forum specifically to discuss any challenges that you are facing while
constructing the model. The teaching team and your fellow peers will be able to assist you in this forum. The more
questions and photos posted and discussed, the better the learning for everyone.
PART A: CONSTRUCT A WALL AND ROOF MODEL (30%)
You are required to construct a wall and roof model.
Assessment will be based upon consistency to the plans, depicting the relevant roof construction and wall frame and
their accurate placement and neatness of presentation.
UO Construction 1
The plans provided on the learn online course site, include a truss roof frame, showing a “hip and valley” roof. Select
one to be constructed.
The model shall show all members of the roof and ceiling framing, including bracing and a portion of the roof battens
and covering, sarking, ceiling material, insulation, and eaves detail. Not all the house roof framing needs to be
undertaken, just enough to adequately describe the hip and valley created from an L-shape portion of the house
The model shall show at least one full length of the wall. All the components of a wall frame should be shown
including bracing. Not all the wall framing needs to be undertaken, just enough to adequately describe the typical
members of a wall. Remember you will need to provide walls to support the rest of the roof frame model. These
walls can be solid wall, used for the remainder of the model.
Construct the wall and roof model from balsa wood or similar material, angle cut to the sections to length and
as close as possible to the scaled size of the actual members in the house wall and roof design. The roof shall be
positioned on a supporting run of walls made from foam board, ‘Masonite’ or similar (except for the wall that is built
as per a typical house wall frame).
The whole model shall be mounted on a stable sheet base. Include your name on the base so as it is visible when
taking your photographs.
The submission of your model will be online so consider carefully documenting and depicting your complete
model. A minimum of 10 photographs presented professionally in a word document that provides a detailed view of
your model with clear labelling of key components and members of the wall and roof frame.
PART B: WORKS SCHEDULE (10%)
You are also required to create a works schedule that describes key stages of the construction process. It is expected
that the works schedule will detail the tasks involved in completing the main stages in your build,
duration/estimates, showing how long each of these tasks took and materials/resources, detailing the materials and
resources involved. It is suggested to convey this information professionally in table format.
GUIDE TO CONSTRUCTION OF A WALL AND ROOF MODEL
PLEASE READ THE FOLLOWING AS A GUIDE THAT ACCOMPANIES THE WALL AND ROOF MODEL ASSESSMENT TASK DESCRIPTION.
This guide provides information that you may find useful to assemble your model as well as details of where the
materials can be purchased. It is a GUIDE only…
• A suggested scale is 1:20, 1:25, 1:30 or 1:40.
• The building platform can be 5mm-6mm thick by 650mm X 450mm (approx.) plastic board, i.e. thin type
webbing between the top and bottom (like cardboard). The same or similar cardboard may be used to make
the walls of the building (except for the wall that will be depicting a wall frame). A piece of timber board may
also be used as a base to support your model.
• It is recommended that the main structure is made from Balsa wood; however, you may choose to use an
alternative material if you deem it to be suitable.
• The materials that you would need to undertake the project are available from most hobby and crafts shops,
and some might be available from a hardware store.
• You will also need to determine the quantity of material required. You may opt to buy a complete sheet and
cut from this sheet rather than purchase individual pieces. For example, cut your rafters from 3-4mm thick
balsa wood sheets.
• Use pins and/or glue to construct the model and make connections.
• You will have to determine the type of roof that you wish to construct dependent on the design that you
have selected. Suggestion: to meet assessment criteria, it is recommended that you use an L-shaped design
UO Construction 1
because it helps you to demonstrate required features of the project such as hips, ridge, gable, and valleys
including ceiling joists, hanging beams, trimmers, purlins, struts, strutting beams, under purlins and facia
• If you have selected to show a section with a truss this should be detailed with information.
• The length of the wall should show top and bottom plates, studs, jamb studs, noggings, and lintels over
INTERPRETING AND READING PLANS
Assessment will be based upon consistency to plans, depicting all relevant wall and roof framing members and their
accurate placement and neatness of presentation. You may want to watch the following. It takes you through the
process of learning how to read typical construction drawings.
• Lynda.com course (2hr 20min, Beginner) – Rogers J no date, Construction Management: Readings Drawings
& Specifications, course, Lynda.com
You may also come across the roof and wall frame terms that you are not familiar with during the course and when
reading the plans for the construction of your wall and roof model. As would happen when working in the industry,
you are required to research these terms. A good resource that you may be able to borrow from a library or refer to
the eReading tab at the top of the course page, or purchase is the book: Wilkie, G 2011, Building your Own Home A
comprehensive guide for Owners-Builders, 3rd Edition, New Holland Publishers, Australia.
• Refer to the learnonline course site under resources for assessment exemplars.
• Assessment 2 Part A and B are to be submitted together as a one-word document.
• Please use the course Q and A forum to discuss any challenges that you are facing while constructing the
model. The teaching team and your fellow peers will be able to assist you in this forum. The more questions
and photos posted and discussed, the better the learning for everyone.
