We recently carried out a detailed topographic survey along the proposed
route of the Caernarfon bypass, in North Wales, for civil engineering
contractors Balfour Beatty and Jones Bros. The survey was
commissioned to allow their designers, Parsons Brinckerhoff, to create a
design for the new road alignment.
The survey followed the route of the proposed 10km bypass covering an
area of approximately 2,500,000 square metres and involved surveying
the existing A487 at each end and other roads crossing the route under
traffic management. The remainder of the survey crossed the surrounding
farmland, woodland and rivers.
The survey was carried out using GPS RTK surveying method together
with total stations for areas where a higher precision was required.
Along with the survey, we also left behind a control network, tied into the
Ordnance Survey Active GPS network.
We supplied the client with CAD drawings and MX Genio files of the
completed survey.
