Value Engineering

“RMA had to liaise with both Origin Energy and the contractor to deliver their engineering recommendations within the context of a tight procurement schedule.  They delivered on time and the recommendations included an alternative road pavement design which considered locally sourced gravel material.”

Origin Senior Project Engineer Adrian Moon

RMA was engaged to advise on the redesign of the access road to this site to optimise the design and reduce construction costs.  The key issue was that access to gravel that complies with TMR specification (Type 2 unbound granular material) was limited and required haulage from a quarry in the order of 200km away.

The cost of transporting gravel over this distance would have been prohibitive, so RMA engineers investigated the option to use lower grade (Type 4) material that was readily available in a nearby quarry.

Our soils and road design specialists were able to optimise the pavement design to utilise the local materials, and also specified a process to properly lay and compact the material to meet the appropriate road building standards.

Advantages of RMA’s Input

RMA’s engineered pavement design and more strategic use of local materials has ensured the road is fit for purpose, meets the required TMR design standards and is more cost effective than an “off the shelf” design.
