These surveys typically involve undertaking one or all of the following three phases, all of which are crucial in the construction of wiring or the adjustment of wiring above tracks:
- Set out of the proposed OHW structure bases for PPs, FSAMs, cantilevers, portals and signal gantries
- Survey checks of the constructed OHW bases
- C-Calc surveys: showing the newly constructed OHWS and wires in relation to design alignments and existing tracks
Meadows Consulting has many years of experience in providing these surveys for clients.
