The Companies surveys are produced by experienced Surveyors using the latest surveying equipment, and techniques. These include electronic "Total Station" Theodolites that read and record observations automatically using infra red "distomats" for distance and electronic sensing for Vertical and Horizontal angles.

As well as the conventional 2D drawings the CAD facility enables us to offer additional information not possible on a conventional plan; 3D computer models for detail design, ‘walk throughs’ and visualisation; data collection for Facilities Management and Geographic Information Systems.

Output data can be in a wide variety of formats using translation software developed by the company. Data structure and layering can be to BS1192 Pt.5 or to any other standards or tailored to your own specific requirements.

Our Computer Systems Director, Richard Hart, was Chairman of the Mapping and Geographic SIG of the Autodesk User Group and served on another Special Interest Group making recommendations to BSI for BS1192 Pt.5.

Should you require further details of our CAD facilities or wish to visit our offices for an In-house demonstration of modern Surveying Techniques please do not hesitate to contact Richard Hart.

The following examples illustrate projects in which E L S Land Consultants have been involved in setting up monitoring systems.

The London Pavilion:-
We undertook precise levelling to a series of points on structural walls whilst a tunnel was excavated below the Building to connect from the nearby Trocedero Development to the main underground concourse of the Piccadilly Tube Station

The Daily Telegraph Building Fleet Street:-
We set up a system of permanent ground points and inclinometers on structures to be retained and neighbouring buildings, to again record initial and periodic measurements to locate any movement horizontally or vertically during the construction of the Peterborough Court Development behind a retained facade to Fleet Street.

Bentalls Department Store, Kingston:-
The famous Aston Webb facade to the Bentalls store which has been retained, was again checked periodically against an initial set of horizontal and vertical dimensions, to monitor for any movement during the complete demolition, excavation and reconstruction of surrounding structures.

We are able to supplement topographical surveys with underground services surveys to plot the route and depth of all underground pipes and cables.

Electronic detection techniques will be used in the location of underground services. The results are not infallible and trial excavations must be carried out to confirm service identification, positions and particularly depths. Although all reasonable effort will be made in searching all available records, the completeness of the underground services survey cannot be guaranteed.

It is not possible to trace non metallic service routes, in the case of such services being present on site we will survey any visible trench scars and refer to existing records. Such detail will be suitably annotated to differentiate between survey information and record details.
