Queensland, Australia - A state of the art facility designed and built as part of a massive $4.4B investment by Queensland Government for the next generation in trains and public transport.
The Wulkuraka New Generation Rollingstock (NGR) Maintenance Centre is a state of the art facility designed and built as part of a massive $4.4B investment by Queensland Government in next generation trains and public transport.
Wulkuraka was developed to not only service and maintain 75 new, high tech passenger trains for the rapidly growing South East Queensland region, but to stay fit for purpose for the next 50 years.
To ensure the design and construction were equally cutting edge, Arcadis set a new benchmark for the use of Building Information Modeling - or BIM - in infrastructure projects in Australia. BIM, which digitally maps the physical world, has been in use in Australian construction for a while, but for the first time Arcadis developed a unified platform able to integrate seven different design software packages.
“By bringing together all the disciplines involved in Wulkuraka as one cohesive digital model, from overhead and underground services to electrical, structural or mechanical engineering, we ensured seamless collaboration right from the start,” said Jaco Le Roux, Urban Development Manager, Arcadis.
“By getting all the outputs into one model we could see what the project would like before it started and that has a huge impact in terms of coordinating works and resolving issues upfront.”
A recent international case study of Wulkuraka found Arcadis’ innovative application of BIM delivered widespread benefits, including better asset management, cost accounting, environmental performance, productivity, safety and fewer errors.
One of the most important was improved construction time lining given the potential for major programming conflicts on a project of this size where over 200 staff could be on site at any one time. The BIM model proved just as valuable in helping to identify and avoid the real potential for clashes in the sheer number of services involved, as well as the capacity to integrate it into construction machinery like earth moving equipment.
Taken together the much higher level of coordination meant early delivery of the project six weeks ahead of schedule, as well as cost savings and a far more efficient use of equipment on site. No wonder Wulkuraka received the 2016 Smart Infrastructure Award to acknowledging how smart technologies-specifically BIM-delivered superior results.
Creating a far more advanced BIM model didn’t come without its challenges of course.
“A lot of work had to be done just to prepare everyone to able to work to the one BIM model,” Le Roux said, “but once that was in place we also needed to make sure we managed the volume of integrated information skillfully and then used the data in an innovative way.”
Now built, Wulkuraka and the ongoing NGR have already had a major impact for the people and economy of Queensland, including around 500 full-time jobs and up to 1,500 indirect jobs drawn from the local and regional community.
“Local participation in the works was approximately 87% because the BIM model enabled the design to be developed to maximize opportunities to engage local companies and workers,” Le Roux said.
