Land Surveying and Mapping
Site surveys and topographical mapping can be undertaken to any desired scale
and degree of detail specification.
- Large scale -
These can be produced at scales up to 1:100 or larger. Selection of scale and
degree of detail to be shown will take into account the size of the area.
- Small & medium
scale - Contours
and spot heights can be added to UK Ordnance Survey maps at 1/1250 or 1/2500 scales.
A careful balance must be struck between the need to show clearly all the desired
information, keeping the number of plans manageable and fulfilling the needs of
the design project and of budgetary constraints.
- Additional information
- such as longitudinal or cross-sections in drawn or tabular forms, volumetric earthworks
quantities and digital terrain models can be produced as a by-product of the
mapping process to meet the special needs of the clients.
- Consultation -
Many years experience, working in close day-to-day liaison with design teams,
has proved to us the inadequacy of working to generalised 'standard specifications'.
No two projects have identical needs, so we aim for a flexible approach in determining
We will supply to clients, on request, a printed pro-forma listing typical specification
options available (such as scales; grids and datums; degrees of planimetric information;
height information; underground services and methods of presentation of results)
from which items not required can simply be deleted.

All types and scales of mapping require the establishment of an accurate framework of
control points, established by GPS or Total Station/EDM equipment.
The types of mapping
projects undertaken by Glen Surveys include:
- Revision and contouring
of existing maps for planning purposes.
- Site surveys for
housing authorities and estate developers
- Town centre redevelopment
- Route plans and
profiles for power lines and pipelines
- Engineering surveys
for highways and bridges; docks and harbours; tunnels; railways; airports; oil
installations; power stations; sewerage schemes; irrigation; water supply; industrial
and residential development

- A one-off fee
can be negotiated for the entire operation
- Fully equipped
survey teams can be provided on inclusive time rates
Glen Surveys can
carry out a proving survey to check the design control framework and to ensure
that the project fits the site. Initial setting out can be followed up with periodic
visits to check and maintain progress. As-built surveys can also be carried out
on completion of the setting out as part of our quality control procedures.
can be seconded to work directly under the client's own control and supervision.
This can be for various periods of time and charges can be negotiated at flat
rates with no hidden extras.
We would emphasise
that Glen Surveys is a professional survey company, not an agency. Staff
provided on secondment to clients are qualified land surveyors and have the full
range of equipment and technical resources at their disposal.

Architectural and Structural Surveys
Large scale floor plans, elevations and sections of existing buildings can be
provided for reconstruction or refurbishment projects. Floor plans can be related to a rigid control
framework for three-dimensional structural engineering design, or more economical
individual plans of each floor can be provided for architectural, refurbishment
or letting purposes.
showing main outlines with window and door openings can be produced economically
by conventional survey techniques using remote methods and reflectorless instruments.
If detailed elevations, including all architectural embellishments are required,
we can arrange the use of specialised terrestrial photogrammetry or laser scanning.

High Precision Measurement and Monitoring
New and old structures can sometimes be subject to settlement or subsidence resulting
in structural movement or deformation, both during and after construction.
Glen Surveys has,
on many occasions, undertaken precise measurement using specially calibrated tapes,
electronic equipment, geodetic levels with parallel plate micrometers and invar
staves, precise digital levels with invar bar coded staves, in order to monitor movement on a regular basis over a period of time.
We have considerable experience in preparing contoured topographical plans in
2D or 3D for modelling purposes, using vertical aerial photography and computerised
This method is
particularly economical for large areas of township or rural environment or where
access is difficult or prohibited on the ground. Stereo aerial photography provides
a powerful source material for infra-structure mapping at both large and small
scales, with output in MOSS or AUTOCAD formats.
We are able to undertake the location of underground services by visual inspection
or by electronic tracing methods, and record their condition using CCTV methods.
Manhole depths and positions can also be recorded and superimposed onto our topographical
surveys of the ground above. By using up to the minute electro-magnetic survey
equipment we can detect underground metallic pipes, cables and drains to show
their exact position, depth and if required photographic evidence, plotted on
to a survey drawing.

In cases where two parties are in dispute over property boundaries, or planning
application issues, Glen Surveys can provide a professional qualified Land Surveyor to act as an independant expert witness in accordance with the Civil
Procedure Rules 1998 with overriding duty to the court.
Our surveyor will examine the existing documentation, carry out a measured survey
on the site and prepare plans and reports for the court, and if necessary, determine the boundary line for H.M. Land Registry and give
evidence as an Expert Witness.

CAD & Digital
All field survey observations are processed at our Sidcup offices, using experienced
CAD operators and state of the art computing technology, enabling us to offer
a fast, efficient and versatile service. Increased accuracy, enhanced
productivity and less risk of human error result in faster job turnaround times
using the latest AUTOCAD software package and online precision colour plotter.
