Article 6 - Industry Steels Itself For Rises
Industry Steels Itself For Rises
National Building News
May 2008, Volume 8, Number 4.
The cost of iron ore and metallurgical coal is rising rapidly due to an increase in steel production, combined with the recent disruptions in the supply of steel around the world. Companies like BlueScope Steel and OneSteel have both raised the prices across their product ranges, to cope with the rising costs of raw materials. As global prices for iron ore and coal are sky-rocketing, there is a concern here in Australia that commercial construction costs will surge as costs inevitably will be passed on to the consumer. However, the discontinued use of steel on major projects remains low, this is mostly because steel provides an ease and speed of construction, which helps it to remain competitive in the building industry. It is important to note that rising costs in steel is not directly attributed to the cost of organising structural steel on construction sites.

Article 5 - Sustainable Specification For Building
Environ Magazine - Sustainability - Design - Products
Winter 2008, Pg 10.
Envirospec have developed an equitable product specification which defines a practical system of comparison between competing building products, enabling the consumer to easily identify the products contribution to sustainability. This inclusive life-cycle analysis is slightly contentious however, as many assumptions are made in reference to the manufacture, transport, construction, demolition, and even the products in-service performance. ‘In-service performance’ for example, is the specification of levels of insulation to achieve desired energy minimisation.
The second part of the protocol provides for collection of data for subsequent use in life-cycle analysis. Once all the information is gathered it will, then become part of this new specification and environmental declaration.
The CodeMark Scheme enables Architects, Builders, Engineers to choose building products, that they can be sure meet the expectations of the Building Code of Australia.

Site Visit 6
New Shopping Centre on the corner of Koornang Road and Dandenong Road, Murrumbeena, Melbourne.
Here you can see steel reinforcement being craned onto the 3rd story in preparation for a concrete pour.
You can see a pipe line here. This pipe line goes for miles and is pumping concrete from the basement all the way up onto the 3rd level where the workers have been laying reinforcement.
These columns are close to full strength, almost ready for the next stage of construction. You can see the starter bars above the ligatures and internal column reinforcement, they have been left exposed in readiness for the 3rd level concrete floor slab.
This scissor lift (and the fact that this site is a Union site) is the reason I cannot go up and watch the concrete pour. All workers have to be raised up to the next level by this lift. The site is bustling, and i was very lucky to be allowed on site. 
This, I have been told by one of the consruction workers on site, is a post-tension cable. I thought it an interesting photo for inclusion on my blog.

Dead loads can be seen here. Steel formwork, having been dismantled from lower levels and now waiting to be re-used as this shopping centre quickly gains height and breadth.
