The $59 million Nundah Bank Third Track project involves the triplication of the line on a section of track where trains have been slowed due to the gradient of the climb up the Nundah Bank. This project is part of a significant program of works to be delivered by the Upper Hunter Valley Alliance (UHVA) which was formed by the Australian Rail and Track Corporation (ARTC) in 2009. The alliance is comprised of ARTC, Leighton Contractors, Parsons Brinckerhoff, Coffey Geotechnics and KMH Environmental. KMH provides UHVA with the Environmental Management Team.
One of the many roles of this team is to provide soil conservation and erosion and sediment control (ERSED) advice onsite. Specifically on the Nundah Bank project, KMH prepared the baseline soil and water management plans and have prepared the ongoing progressive erosion and sediment control plans and rehabilitation plans. A key issue was separation of “clean” waters from “dirty” construction waters and establishing practical, cost effective temporary cleanwater crossings, of which there are many. KMH provided advice for design and management of sediment basins and minor sediment traps, using sediment fence, mulch and earth materials. KMH have provided ongoing soil conservation support to project engineers and construction personnel, through regular inspections, preparation of inspection reports and action plans, and proactively engaging with site personnel to build capacity in identifying and managing ERSED risks.
