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

https://unisa.sparkplus.com.au/login.php

– 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.

http://spatialwebapps.environment.sa.gov.au/naturemaps/?locale=en-us&viewer=naturemaps

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 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
