Dahua Group’s inaugural release of their 1881 Tullimbar development consists of approximately 150 residential lots split across Stages 1A and 2 and a shared park between the two stages. The development is a continuation of the recent boom in the Illawarra and South Coast region and offers prospective home buyers the rare opportunity of both coastal and escarpment views whilst living the quiet suburban lifestyle. 

Orion Consulting was engaged by Dahua Group to provide Superintendent services for the delivery of Stages 1A and 2. This was inclusive of demolition and site remediation works, extensive rock processing and delivery of civil and utility infrastructure to service the 150 residential lots. 

Upon breaking ground, it was evident that the extent and classification of the rock was far greater than that identified in the preliminary Geotechnical reports. This placed the program and targeted end of year settlements at great risk to the client, whilst also placing additional pressure on the contractor in which rock was priced into the lump sum contract.  

Orion Consulting, working collaboratively with Dahua Group and the Principal Contractor, was able to gain approval from Shellharbour City Council to undertake rock blasting. This led to a significant increase in onsite production and alleviated a significant portion of risk to the targeted settlement dates. 

The value of the blasting was collectively recognised between the client, contractor, and future home buyers. The efficiency in this removal method mitigated the initial rock delays and placed the program back on track, ensuring these initial stages are released in a timely manner to the future lot owners. 

The expected long-term benefit of the above approval is significant, with additional cost and time savings expected on all future stages in which rock of similar characteristics is encountered. The collective benefit blasting had on all stakeholders involved, including the local residents who were spared extensive rock hammering, has Orion Consulting excited at the opportunity to integrate its use on future projects.
