Plowman Craven is currently the chosen surveyor on some of the UK's most prestigious rail projects
London Bridge Station is the 'jewel in the crown' on the £5 billion Thameslink upgrade programme and Plowman Craven has the mammoth task of measuring every part of the Station's intricate array of arches and heritage structures. Using 3D laser scanning instruments (including the latest Leica C10 scanstation) and GPS, the 10 surveyors on the project are supported by a dedicated on site office team processing one billion points of measurement data collected every day. The integrated 'scan-cloud' and photography will form the database of measurement to be shared by all parties to the development.
Measurement to 1mm accuracy is demanding but when 'Slabtrack' pouring in difficult environments demands this, Plowman Craven has brought in its expertise and the latest Amberg Track Measuring System to the high profile Southampton Tunnel project.
Crossrail has called on Plowman Craven for the last 15 years to provide survey data of varying types for the advance planning of Europe's major rail construction project which was given the go-ahead in 2009. Now Plowman Craven is busy establishing high precision surveying control and laser scanning data through some of LUL's structures which interact with the Crossrail route. Plowman Craven is currently commissioned on five projects for Crossrail.
