Interview with
Dr Srijib Chakrabarti
Principal Geotechnical Engineer

Dr Sri Chakrabarti is a Principal Geotechnical Engineer in Perth, Western Australia.

Sri shares with us one of his most memorable projects ....

One of my most memorable projects was the Barrow Island Airport Upgrade located on a remote island off the coast of WA and was a key infrastructure component for construction of the Gorgon LNG project.

I was responsible for the design and construction of the upgrade to the airport runway as the existing pavement was found to be inadequate to withstand the jet aircraft traffic between mainland WA and the island.  

Between 2010 and 2012, cement stabilisation was carried out on the existing pavements, the runway resurfaced using sprayed seal and emulsion sand overspray (sand seal), and this was all completed without disruption to the jet aircraft traffic. Once completed I was responsible for the ongoing assessment of the structural condition of the pavements and provided design and construction support for the asphalt overlay. This was achieved by using an innovative rut resistant asphalt bitumen modified with Ethylene Vinyl Acetate (EVA) around 2012/2013.

The success of this important infrastructure project was most rewarding given the remote location and stringent quarantine requirements.

The success of this important infrastructure project was most rewarding given the remote location and stringent quarantine requirements.And I’m pleased to say eight years on the airport pavements are performing well!

I enjoy working at Coffey as you are encouraged to think outside the box to provide tailored solutions across often difficult and challenging projects. I’ve been fortunate with the opportunities I’ve had over the last 15 years, a prime example being that of the Barrow Island Airport Upgrade project.

 Congratulations Sri on reaching this important and significant service milestone.
