STATE DRILL CORE LIBRARY FACILITY
DESIGN BRIEF (V2)
1. PROJECT BACKGROUND The South Australian Drill Core Reference Library hosts geological samples recovered from
over 130 years of exploration for minerals and energy resources in South Australia. These
irreplaceable samples represent valuable direct records of the geological materials retrieved
from the depths of the crust, which will continue to be investigated and analysed by new
generations of geologists in industry, research, education and government. The facility
consists of three main areas, that vary in use and their design and construction methods; the
hylogger, the library and the administration building. The facility was constructed in 2015 as
part of the Tonsley Redevelopment, Clovelly Park.
2. PROJECT SCOPE The scope of this project is to design and document some of the main structural roof and floor
elements for the Administration Building of the State Drill Core Library Facility. The focus will
be on the part of the building located between Grids AA and AE, A4 to A20 on Structural
Drawings ST-101, ST-102, ST-302, ST-301 and Architectural Drawing A126 and A127.
Firstly determine the design loads on the building (remember to consider the whole building
for wind loads) and then design the structural framing members using steel and then timber.
The structural elements you will be designing are a roof beam, column, lateral bracing system
and a connection detail (for bonus marks).
The following items are not in the scope of this project:
• Any concrete elements including the design of the first floor slab
• Earthquake design
• Fire resistance design
• Ground floor slab or footing design
3. DESIGN CONSTRUCTION – LIBRARY a) Ground and first floor exterior walls: Lightweight stud wall or glazing with aluminium
composite façade panels supported on steel framed fascia trusses. Refer to Architectural drawing A200 for details.
b) Roof: Metal sheeting with insulation under, on steel purlins and rafters as shown on the architectural drawings A300, A301 and section details drawings (A620, A621, A622 and A623).
c) The ground floor is an industrial raft slab on ground with pad footings.

4. PROJECT TEAM
For each design you are required to work in a project team of three (3). Each team will be
more effective in their effort to address the project scope in the time duration allowed than
an individual. If there are an uneven number of students in the class, one group of four (4)
students ONLY will be allowed. Please submit your preferred groups in an email to your tutor
by the end of Week 2. All team members MUST be in the same timetabled design project
session.
Please note the initials of the student responsible for particular calculations on each page or include a summary of the work distribution between the team members in each of your submitted reports.
5. PROJECT ASSESSMENT This total design project is worth 35 % of the course assessment separated into 3 submissions. Stage 1 Design Loads
Stage 2 Steel Member Design
Stage 3 Timber Member Design
The detail for the elements required to be designed by your team, the allocated marks and
suggested completion dates are documented in the tables in the last pages of this brief.
6. PEER ASSESSMENT At the end of each submission stage of the design project, you are required to assess yourself
and your group members using the online peer assessment tool SPARK.
(https://unisa.sparkplus.com.au/login.php) You are required to answer each of the criteria
questions and provide written feedback of at least 10 words for EACH group member. The
RPF factor from SPARK (along with tutor and lecturer observations) will be used to modify
your groups’ mark to give you an individual mark for each stage of the design project.
Please note that marks have been allocated for the group to successfully complete this peer
assessment. If any of your group members fail to complete this peer assessment fully within
the allocated time frame, your group will receive a reduction in marks for this part of the
assessment. If ALL of your group members do not complete this, you will receive zero marks.
7. DESIGN METHOD and SOFTWARE USE The calculations should be typed. The calculations MUST be neat, tidy, legible, easy to follow
and logically laid out. You may use spreadsheets to make your calculations clear for repetitive
iterations as long as the first iteration including all the formula and workings are typed.
You are to use the structural analysis software Spacegass to analyse the roof wind truss ONLY to obtain the design actions including the bending moments, shear forces, axial loads for the roof wind truss / bracing members. You must provide detailed calculations for how you arrived at the input data using a cover sheet for any computer output. The cover sheet will detail all the input you have entered into the software including:
- Dimensional information between grid lines and other setout information - Dead, live and wind load cases labelled, locations, direction and values identified
2021 Steel & Timber Design Project
CIVE 3013 Steel and Timber Design Page 3 of 8
- Labelled member sizes and connection types ie pinned, roller, fixed
Spacegass is installed in the computer pools in Buildings F, N and P. Also a Spacegass student
version can be installed for free on your own laptop / home IBM compatible PC, downloaded
from the Spacegass website using this link: http://www.spacegass.com/student
You will need to enter your student details (name and email) to confirm that you are a
student. Please put Khoi Nguyen as the lecturer and email address is
8. ADDITIONAL DESIGN INFORMATION Dead Loads For the roof dead load you will need to determine the self-weight of the sheeting, purlins,
insulation and ceiling. For the mechanical and electrical services within the ceiling space,
allow an additional dead load of 0.7kPa. This is in addition to the dead load for the self-
weight that you have calculated.
Tip: Apply the services dead load for the downward case only. Do not add the services dead
load in combination with the upward wind load. The exact location of services is unknown,
therefore we assume the most conservative loading conditions for both the downward and
upward loads. For instance, the maximum dead load for downwards and minimum dead
load added to the upward loads from the wind combination.
Wind Loads The building is located adjacent South Road, Clovelly Park, South Australia. The facility is located on the side of a hill so use the website NatureMaps to determine if topographic multipliers will affect the wind speed. The wind load will vary according to the geometry of the building.
Roof & Floor Beams The roof sheeting will be fixed to purlins running along the length of the building
(approximately north-south for the particular section we are designing). They will be bolted
to cleats (small plates) that are welded to the top flange of the roof beams hence provide
lateral restraint to the top flange of these beams. Roof beams are usually Universal Beam
(UB) or Parallel Flange Channels (PFC) sections bending about their major X axis. Long span
roof beams may be pre-cambered upwards to balance downward deflection. This should be
considered in your design.
Columns Structural columns are located at each end of the roof beams. Columns can be constructed
from rectangular hollow sections (RHS), square hollow sections (SHS) or Universal
Beam/Column sections (UB/UC). The walls will provide buckling restraint under axial loads
for any columns.

10. PLAGIARISM IN PROJECTS
Plagiarism is a specific form of academic misconduct and deliberate plagiarism is regarded as a serious act of academic misconduct. For a more detailed explanation of plagiarism, please refer to https://lo.unisa.edu.au/mod/book/view.php?id=252142
With regard to this design project, and any other group assignments, plagiarism can be difficult to define. Within the profession of engineering, working in teams is the normal means of operating, and group projects and assignments are partially designed to give students experience in this process before they enter the workforce. When undertaking the design project, you are encouraged to work very closely with your team partners, and also to discuss issues with other groups working on the project.
However, each project submission must be the INDEPENDENT work of that group.
2021 Steel & Timber Design Project
CIVE 3013 Steel and Timber Design Page 5 of 8
In the normal design process, there are many decisions to be made that will be based on opinion and judgement, e.g. the design wind speed, the most economical member type to select, reinforcement bar size and layout etc. It is expected and encouraged that students will discuss these decisions with each other. However, the final submission for a project must be the outcome of that group’s decisions and judgements. Given the large number of opportunities within a project for different decisions to be made, it could not be possible for two design projects to be exactly the same, even though the assigned problem is the same. In addition, the layout and order of calculations, headings used, drawing layout and style will be unique to each project. Hence, plagiarism in projects is quite easy to detect, and any such submissions in this course will be penalised in assessment in accordance with the academic misconduct policies of the university.
11. PROJECT PRESENTATION The project shall be presented as a typed hardcopy, fixed either in a ring binder folder or stapled in the top left hand corner. In addition, each submission stage must be uploaded to the course home page in pdf format as one single file.
The format shall include:
• Team names on the front cover
• Disclaimer that project is your own work (i.e. you and your groups)
• Index
• Calculations
• Drawings (A3 maximum size, A4 size is acceptable at a reasonable and readable scale)
Please DO NOT use a “Display” folder with individual sheets within the plastic covers.
12. DRAWINGS The documentation you prepare will include typed calculations and drawings. The design
drawings you provide should summarise your design. The drawings should include a layout
plan, member sizes and critical structural dimensions to scale. Electronic drawings or neat,
ruled hand drawn sketches can be submitted.
