Topographical survey highway junctions

Highways

Merrett Survey Limited has worked across all types of road survey, for new build, improvements, widening schemes and maintenance, in all regions of the UK and around the World. This has included all grades of road from motorways, dual carriageways, bypasses, urban, rural and gravel roads across Africa. We have even surveyed a road made of coral in the Philippines !

Typical projects have included:-

  • Site surveys for ‘intelligent motorway’ signage.
  • Bypasses.
  • New and re-designed roundabouts and junctions.
  • Bridge clearances undertaken by laser scanning.
  • Bridge condition surveys using laser scanning and 3D modelling.
  • Structure monitoring.
  • Bridge joint replacement surveys.
  • Highways surfaces – high precision levelling work – volumes of overlay.
  • Primary and secondary geodetic control networks.
  • Drainage asset surveys – manholes, drain CCTV inspection.
  • Utility services – UUD (underground utility detection) / GPR (ground penetrating radar).
  • Road clearance surveys – for the passage of abnormal loads such as wind turbines / blades.
  • Cadastral survey for land ownership and compulsory purchase.
  • Noise studies.
  • Mobile mapping – vehicle based laser scanning – for highway topographical survey.
  • Cycle lanes – cycle tracks.
  • Dedicated bus lanes – some of this work was undertaken for Transport for London prior to the 2012 Olympics.
