Footings
John Doak a commercial/residential builder in
the Geelong district from Impact Property
Development, recommended for this
development that we use a concrete raft slab
roughly between 200mm and 500mm
depending on soil type and an engineers report.

Warehouse Surface
The Installation of a epoxy resin floor finish will be
required. A mixture of polymeric and polyurethane will
provide a durable surface area to protect against
abrasion and chemical spillage. The floor surface will be
around 1mm thick. This surface system is called F-100
high performance epoxy resin floor finish. There is an
option of a conductive or an anti static finish. The floor
colour will be a light blue colour to allow for spills and
other hazards to be detected. This type of flooring
system meets Australian Standards.

Portal Frames
Definition: A continuous ridged frame with a
restrained joint between the column and beam.
The frame will act as one structural entity.
Source: SRT 251 Construction & Structures 2 Lecture Notes
Group Definition: Large spaning framework
structure consisting of knee joints between the
columns and rafters allowing for a large column
free open space.

Benefits of Portal Frames
Large open space
• Easy to assemble
• Cost effective
• Time saving
• Not labour intensive

General Structure Knee Joint
The joining between the u.b rafter
usually consists of either a -
•Butt weld
•Hit and miss weld, or
•Fillet weld
As well as large galvanized bolts.
This solid join allows the live loads
such as wind loads to be directed into
the footing.
8
General Structure - Apex or Ridge
This is the highest point in the
framing. It is important that
appropriate welds and bolts are
used to fix this point together.
9
General Structure – HD Connection
Bolts
HD bolts are set into the
concrete footings of the
slab. The columns then
slip over the top of these
and are bolted in place.
The bolts are then
welded tight so they can’t
undo. The exposed bolts
and base of the column
are then encased in
concrete up to the level
of the slab floor, sealing
them in.

Cladding
Alucobond has been an option for cladding in our building. This
product is a light material and is easy to work with as well as
flexible and smooth. This product is made up of two aluminium
sheets and an inside of plastic. Its weather resistant and shock
resistant witch makes is a perfect material for external cladding.
It comes in a standard thickness of 4mm but can be requested at
sizes ranging from 3 to 6mm. It’s standard sizes are 1000, 1250,
1500 by 3200mm and it can be requested to a max width of 1575
and length of 8000mm. It comes in a range of up to 24 different
colours witch you can requested on order. The product has to meet
Australian Standards 1530 when regarding insulation and fire
protection. Other additional products include Alucobond Plus (one
side stove-lacquered finished) and Alucobond A2 (one side stove
lacquered).

Roofing Members
‘C’ Purlins run from rafter to rafter, fixed by
four bolt cleats which are welded to the
rafters and bolted to the purlins.
Fly bracing is also used to strengthen the
‘C’ purlins connection with the rafters.
This helps with resistance against wind
uplift and other live loads.

Roofing Members
Over the purlins we lay safety mesh before
placing insulation over the mesh. The
safety mesh is connected to the purlins
using Tech screws and washers.
The insulation used is industrial glasswool
with thermal foil underside.

Roof Cladding
High tensile steel roof sheeting is used for our
roof cladding. It is lightweight has good
spanning capability and is resilient to rough
conditions. It requires four fasteners per sheet
to perform to its required standard. The sheets
are connected using waterproof tech screws
which drill into the purlins.

Pre-cast Panels
The reason why we chose this system is
because of the following points
A.
B.
C.
D.
Easiness of erection thus saving on labour
costs
Its pre fabricated therefore increasing
product quality, simplicity and time
Used as a structural element
Elements can be reproduced with ease due
to per-fabricated forme work
