12、g collaboration with a range of consultants. the conceptual design for ch2 was developed by an integrated design team during a two-week intensive workshop or charrette in january 2002. intense cooperation early in the design process is unusual and, in the case of ch2, this enabled innovative decisio

17、n building design. the issue of risk influenced the procurement choice for ch2, with project director for the city of melbourne, rob adams, saying:“i think if you look at the process of procuring the building it is very traditional it is full documentation, guaranteed bill of quantities, the stuff t

18、hat people used to do 10-15 years ago. i have a great belief that it is at the front of the project where you need to do the work. our industry has moved away from this approach and although they have cut down on consultants fees and save two to three per cent, they then wonder why it blows out at t

20、 hansen yuncken, confirmed as many contracts as possible early in the construction process. in contrast to other construction firms, hansen yuncken only employed a small core team. during construction, the company continued to research and advise the client on the availability and cost of some of th

21、e more unusual or innovative provisional elements of the design. for example, it was a challenge to find provisional items such as timber windows and rotating timber shutters that satisfied esd, performance and cost criteria, and could also be delivered in a timely manner. sourcing materials during

22、the time the project was tendered and construction began, some issues were experienced relating to sourcing materials and changing costs. some materials had become difficult to source, others had become more expensive. the cost of steel from china, for example, doubled. recycled timber was easy to s

23、ource but it was more expensive than new timber and its density meant extra cutting costs due to the need to replace blades. issues to do with the use of pvc, recycled steel and cement replacement with fly-ash are also described in the paper. in addition, hansen yuncken faced a dilemma when comparin

25、tforward. hansen yuncken carefully selected subcontractors and many had worked with the company before. there was also a lot of goodwill for the project from the contractors, with the larger firms keen to be involved to boost their green building skills and credentials. a key sustainability issue du

26、ring the construction phase was waste recycling. a simple strategy was developed as part of hansen yunckens environmental management plan. a waste contractor provided one bin onsite for waste and then sorted the residual material offsite with a recycling success rate of around 80 per cent. the remai

27、ning 20 per cent was committed to landfill. the cost of transport and sorting of waste were carried by the recycler and recouped through the sale of recyclable materials. for this reason, site induction on waste procedures was relatively straightforward. all building waste went into one bin while do
