Site Visits

Site Visit to a Site Redevelopment from public space to shop/mall style area in Torquay.

This image shows the overall view of one of the smaller shops, the whole development is of a pretty big space. Tilt-up construction was being used, and precast concrete panels were in the process of being erected.


View of the Box Guttering used, with a Spandek-style support. Extremely similar to the details we drew in tutorials.


Close up of the Box Gutter, and the drainage system. I think the pipe may either be for some kind of overflow protection, or for a tank or recycled water system.


View of the roof system with box guttering. Also visible is cross0bracing on the roof, and the reinforcement and waterproof membrane in preparation for the slab pour.


More of the roofing system, which was quite complex as the building was a slightly deformed 'L' shape. Much of the system seemed to have been prefabricated, then welded on site. Fly-bracing between rafters and Z purlins is also visible.


Here we can see the safety mesh and cross-bracing on the roof/ceiling. The large open expanse below the heavily braced upper wall will hold glazing at a later stage.


A bolted connection, and also welded connections. The girts are also visible, used here as a different cladding material is being implemented.

Image showing the use of timber and steel together, due to cost versus performance decisions. Here the joins were all welded.


A welded connection, also visible are the bolt holes, used to construct the frame, and then removed when the joins are welded. This was done as timber will later be fixed into the I beams to allow other materials to be fixed to this easily.


Overall view...


Steel framed Carport, Torquay

Steel columns, hollow rolled sections propped in preparation for steel beams, which will be placed in the seat formed at the top of the column.


A bolted connection will be used here. Manufactured steel is accurate, therefore all these holes are pre-drilled.


Very simple use of dynabolts to connect column to slab, used here because of the lesser load being carried.


Interior Views of a Curved Steel Roof Truss

Image showing cleats and bolts connecting truss to timber purlins. Also the aluminium windows are secured directly to the truss.


The Span of the trusses. Timber purlins are set at the height of the trusses to enable the curve of the roof to sit firmly against the manufactured curve of the truss.


A random view of cleats I found under a deck....

Glenn Murcutt

I have chosen Glenn Murcutt as my Master Architect for the architecture side of the major assignment.
I felt his 'Australian-ised' work was interesting, and his inspirations, which include shearing sheds, were appropriate for this project. The following images were ones I found which contributed to my decision.






The main features that I plan to incorporate include corrugated iron cladding, some form of exposed or feature down pipes, along with box gutters. Also glazing for light and warmth, and possibly louvres to allow ventilation. Curving roofs could also be interesting...

Section through a Multi Level Portal Frame

Long Span Portal Frame Construction Detail 2

Section is of the same structure as previous, however running in a perpendicular direction. The section shows the wall/roof and knee joint, which is important and allows the open span.

I realised after scanning this image in that there is something wrong going on with the top of the wall cladding. This would need to be fixed to the frame somehow, which I'm obviously unsure about...

Oh and i forgot to label the Lysaght kliplock roof @2 degrees :P

Box Gutter Detail

The Box Gutter is used in this occasion, and could be installed as following.

Important aspects include:

The cleats, which are usually 8-10mm thick, and used to attach girts or purlins to the main structure. These are fillet welded to the main frame.

The Gutterboard, which is used to allow walking in the gutter for maintenance. Mesh can also be placed over the gutter to minimise the need for clearing and prevent blocking.

The Lysaght Custom Orb Cladding is attached to the wall frame with girts.

Flashings are important as water is the most problematic aspect in buildings. All roofing materials should overlap and drain into appropriate areas.

Long Span Portal Frame Construction Detail

The following drawing shows the basic construction of a Long Span Building, eg. warehouse, gym, or any other structure that requires a large uninterrupted interior space.

The beam is connected to the staunchion with a bolting configuration, however this could be welded. The knee joint is this meeting between staunchion and beam, and is integral to the efficiency of portal frame design.

The minimum height of the slab above ground level is 75mm.

The minimum overlap between the concrete panel and the Lysaght Custom orb Cladding is 65mm.

An exciting excursion to Bunnings Warehouse

First blog post ever! The photos document a visit to Bunnings Waurn Ponds. In the timber section the long span portal frame was easily photographed.

View of the fixing between internal column and rafter, using a bolting configuration. The gentle slope of the roof can be seen in the rafter angle. Also visible is the central haunching.


The roof cladding is lined with a mesh-like material, and thin tension cross bracings are used to lock the structure together. Light is allowed through the clear sections in the roofing.


More views of the bolting connection, fly bracing is also positioned from the main rafter to support the purlins and prevent twisting.


The wall frame is connected to the column with fly bracing.


Connection used on the roof near an angled corner wall. Angled structural beams are bolted to cleats along the rafter.


View of the span of the interior space.


Cross bracing is used beneath the wall cladding. Because of the lack of wall cladding on the bottom half of the wall, no girts are needed. This allows easy access to the timber 'yard' via vehicles, etc.
