Look out for star picket markers

Our surveyors are working along the alignment gathering essential information to inform our detailed designs and construction activities.

Two rail workers working on the track

The team collect a variety of data and information that helps our construction team minimise impacts and ensures that our works stay within the boundaries of the project design.

As part of our surveying work, you might see survey control markers along the alignment or
in areas where construction is due to commence. 

These markers are star pickets installed to a depth of 1200mm and covered with a PVC cap. 

Please do not disturb these markers if you see them along the alignment, as they ensure our construction works are delivered according to design.
