Baker Street Station is the oldest on the London Underground network, the world’s first underground railway. Opened in 1863, the Station was extended in a piecemeal fashion, with the sub-surface layout being substantially complete by 1930. Extensive structural and refurbishment work was carried out between the 1960’s and 1980’s. This station is a Grade II Listed Building.
Transport for London’s Station Improvement Programme is to ensure all station assets achieve a fair condition with minimum maintenance for ten years. Frankham was commissioned to carry out a Laser Scanning survey in connection with the resurfacing works for Platforms 1-4. The aim of the survey was to provide floor levels for each platform highlighting peaks and troughs in the surface. Additional measurements were also recorded in the plant rooms, circulation areas and corridors underneath the platform thus determining the platform thickness.
The results were presented in the following formats:
- Contours map model of Platforms 1 to 4 indicating the high and low
- 5 metre grid levels with spot levels of localised high and low points
- Coloured elevation-height map
- Typical transverse and longitudinal point cloud section
- Point cloud data compatible for use with Version 7 of Cyclone in .imp file format
- Point Cloud data in .pod file format for use in Bentley Microstation v8i SS2
- Truview images
