Located on Mortlake Road (on the Hopkins Highway) in Warrnambool, this multi store complex (expected to be completed early 2008) is being constructed buy South Melbourne based CE Contruction Engineering.
The total floor area will be 4680 square metres, with the floor and walls constructed of concrete, and the cladding and frame structure constructed of steel.
The complex is single storey, and expected to contain retail stores and a coles supermarket.

Site visit two (09/05/07)
Multi-Store Complex Princes Highway, Geelong
On Wednesday 9th I spoke to Chris of Polaris construction who explained that the building was to be a multi-store complex, with car-park underneath, and raised roof space in the centre for a rockclimbing wall. This was to be constructed in conjunction with Lyons construction.The Structural sytem is a tilt-up portal frame construction. Before the panel props are moved, these must be checked with an engineer. As these are pre-fabricated they are cured before they arrive. The minimum curing time is four days.
Flooring System
The floor is constructed using a post tension slab, which requires less reinforcement and uses suspension cables. On the first day the concrete is poured, the next day, the cables are stressed to 20%, and then five days after that, they are fully stressed (quick curing).
If the slab is on the ground, hold down bolts are used, otherwise cast a footing in the ground then slab around.

Panel to Panel Connection
To achieve panel to panel connection the grout is poured through the liquid tube to seal the two panels together; otherwise ties can be made through cast-in cleats which are then welded to other panels
Each panel weighs approximately 18 tonne, and is 14 metres in length, with a two metre extension on the top.
Roofing System
Once the panels are securely in place, the roof is then loaded on top. Firstly wall ties are connected which are designed to take the beam load, and then are fixed back onto the panels.
Once this is all in place, the roof is loaded with purlins, followed by the fly girts which assist the main rafters in carrying the roof load affectively.
The spacing of the steel columns (which support the roof beams/rafters) across the floor space is eight metres in length, and 19 metres width.

Article-Building with Glass
Constructin the Future
Issue 24 2005
I found this article helpful with my major project as i was considering having an entirely glass front for my warehouse. After reading this however (and teamed with the fact that glass is probably not appropriate when storing things away from direct sunlight) i have considered changing my ideas.
the article stated that issues such as- daylighting standards, energy efficiency, safety, durability, and weahtertightness needed to be assesed when installing a glazed sytem. Also, an important factor that needs to be assessed is the loading on the glass through other structural systems.
Although it did state how creating the glazing in factories improved its quality and minimised potential failure, it also stated that it was in its use that extensive glazing in an inappropriate area became a danger, as the natural properties of glass do not support excessive loading or diverse climatic changes.
Also, the abnormal loading of such elements as explosions, fires, wind driven debris and human impact was investigated to see how a glazed system could cope until failure.
This test was also performed with annealed, toughened, laminated wired and filmed safety glass. With these innovations, the potential risk of life has been lowered, but the article states that building standards must remain the same to minimise the risk of injury or glazing failure.

Article review
Steel Construction vs. Tilt-up construction
The article stated that steel construction was becoming a more widespread system of construction, to to prefabricated steel members now being available, and its attraction due to reasonably efficient construction. Relative to efficiency, the cost of steel can also be less (even than tilt-up construction) if a prefabricated system is used.
Also, one major drawcard in steel construction (especially in commercial construction), is its ability to span greater lengths unsupported than traditional materials.
The arguement for tilt-up concrete construction in preference to steel construction was that in a building over 50,000 square feet, concrete becomes cheaper in construction than steel. Another argument was that the fire protection of concrete tilt-up panels is greater than steel so (applied into an industrial area) more concrete constructed buildings could be place lesser distances to each other than steel.
Also, the prefabricated nature of the tilt-up panel means that once it arrives on site, construction is very efficient, the drawback to this is the expense of large machinery needed to erect the large panels.
Another reason concrete would be more advisable is that over its life span it generally has lower maintenance costs.
My opinion is that they are both effective techniques in building construction due to their strength, and efficiency in construction. However, both must be applied to the right scenario to maxamise the materials capabilities, if safe and efficient construction is wanting to be acheived.

Richard Rogers-INMOS microprocessor factory
The INMOS microprocessor was designed by Richard Rogers and built in Newport, Wales in 1982. What made this design flexible was that it was potentially suitable for construction in a variety of locations. The fact that this factory needed to be constructed quickly meant that Rogers had to incorporate a great deal of prefabricated material into the design. Like the Reliance Controls factory, Rogers brings the structural elements to the exterior, but this time to the roof, and the loads are dispersed across the building using tensile supports.

Richard Rogers-Reliance Controls Factory
Richard Rogers designed the Reliance Controls Factory as part of Team 4 in Swindon, England- 1967.
The factory was deisgned to be economic, efficient in construction, and a 'democratic building' in which the factory was not exclusively divided into labourer and manager components.
making use of cheap and easily accessible material, Rogers, optmised the floor space by pushing the main structural elements to the exterior. However, the natural repitition of the steel columns, bracing and metal cladding give the building an architectural quality.
Also, with exploration into glass walling, Rogers imporved the quality of work conditions-allowing sunlight into the building.
