Route Alignment and Survey Support for Highways That Perform.
From centre-line stake-out to ROW pillar posting, our survey teams support highway and expressway projects with the precision engineers need to move from design to construction with confidence.
From Survey Line to Construction-Ready Alignment.
Highway and road projects live or die on the accuracy of the alignment survey. Centre-line stake-out, right-of-way (ROW) pillar posting, and layout surveys form the backbone of every DPR and construction handover.
ECAC deploys dedicated Total Station survey teams for long-distance road corridors, national highway packages, and expressway projects — translating design drawings into physical markers on the ground that construction crews can build against directly.
Our teams have executed centre-line and ROW work spanning well over a hundred kilometres across single contracts, including national highway and SARDP-NE corridor projects in challenging terrain.
Our Survey Approach
A structured workflow from design drawing to physical markers on site.
Design Review
Alignment drawings and chainage data are reviewed against design coordinates before mobilisation.
Centre-Line Stake-Out
Total Station teams physically mark the road centre-line at regular chainage intervals along the corridor.
ROW Pillar Posting
Right-of-way boundary pillars are set and geo-referenced to formalise the land corridor for construction.
DPR & Handover
Survey data and drawings are compiled to support DPR submission and construction handover.
Engineering Applications
Our highway engineering survey services support projects across national, state, and rural road networks.
National Highways
C/L layout and ROW pillar posting for NH corridors spanning over 100 km.
Expressway Corridors
Survey support for large-scale expressway packages, including hilly and difficult terrain.
Bridge Approach Surveys
Bridge and RE wall surveys supporting drawing preparation and data submission.
Municipal & Local Roads
Topographical and road-widening survey support for municipal-level road works.
Selected Highway Projects
Field-verified survey experience across national highway and expressway packages.
