Reconstruction of 12 roads between Mount Glorious and Kin Kin, covering an area of more than 300km between 29 work sites. Scope included pavement reconstruction, drainage structures, batter stabilisation, rock fill, piling work for retaining wall structures, as well as landscaping. Works were delivered simultaneously with some packages being under construction for the full project duration, while others completed in as little as 3 to 4 weeks. Key to successful delivery was the degree of communication internally and externally.

The project was delivered under a Performance Incentivised Cost Reimbursable (PICR) Contract – a collaborative model used when the project scope and design is not well defined (presenting high potential for cost increase). It was known before construction commenced that there were likely to be an array of changes to the scope of works, not just due to the limited design, but also in the general context of geotechnical projects whereby finalisation of treatments is not truly known until sites are typically excavated to full depth. Being a geotechnical rectification project, latent conditions were the norm as opposed to the exception. The PICR contract model provided maximum flexibility for scope changes, redeployment of resources to other works, and an ability to minimise overall costs (to both Client and Contractor).

Construction started in mid-February 2014 and was completed in late February 2015 ahead of schedule and under budget, despite 300% scope creep and significant rain fall events.

“In the 25 years that I’ve lived in the area – and with all the construction work around here over the years – Seymour Whyte has been very courteous. No other contractor has been so courteous and considerate of the locals. I’d certainly give you an A+
