COOLING
TOWER SURVEYS
We
have an ongoing contract to carry out Shape Surveys and Ground Visual
Defect Surveys at various locations over the country.
Shape
Surveys
Since the collapse of a tower in the 80's remote measurement techniques
have been used to map the actual shape of the shells against their
original design and monitor any changes in the deformation by repeat
surveys on a rolling 3 year programme.
|
|
Recent
advances in instrumentation has allowed a move from twin instrument
optical observations to single instrument reflector less observations
reducing observation times whilst increasing accuracy. |
|
The
observed surface of each tower is then unwrapped and a contoured
plan of deviations from design produced along with
a detailed report.
Ground
Visual Defect Surveys
The survey comprises the recording of cracks and any other visible
defects on the tower shells, shell support columns and pond walls.
Defects
such as cracks, spalling, staining, etc are recorded 3 dimensionally
and plotted onto a projection of the tower. A written report with
photographs is also produced.

MACINTOSH
MILL, MANCHESTER
We were commissioned to undertake a full Topographical survey and
Measured Building survey of an old mill complex in Manchester City
Centre approximately 40, 000 sq metres in size prior to conversion to
apartments.
Data
was collected by a variety of methods depending on the size, shape
and accessibility of the building.
|
 |
|
Floor
Plans - Outline floor plans were produced indicating main walls,
columns, door openings, stairs, windows and indicative floor to
ceiling / beam heights.
Elevations - Detailed drawings were produced for each façade
of the building.
Sections
- Typical sections were produced through each building and AutoCAD
drawings produced.
Context
Photographs - of surrounding buildings were produced digitally,
critical heights were then added and the data supplied electronically
and in printed format.

LIMERICK
UNIVERSITY
Following
ratification of Manchester Commonwealth Games swimming pool we were
instructed to carry out a similar exercise on Ireland's first 50 m
pool at Limerick University.
For
the pool to be ratified as Olympic Standard it had to be constructed
to extremely precise dimensions. The most critical specification
was for length which had to be 50.015± 0.015 m at the minimum
point in each lane. The measurements had to be taken with the pool
in competition conditions i.e. full with water.
A high
precision survey of the tiling from 300 mm above, to 800 mm below
the waterline was undertaken using specially designed equipment
to determine the minimum length of each lane and primary control
points were established approximately 1050 mm outside the pools'
tiled faces.

GMPTE
- METROLINK EXTENSION
The
existing Greater Manchester Metrolink System which began running in
1992 has proved such a success that plans to expand the network
adding a further 7 routes, Oldham to Rochdale, Ashton Under Lyne,
Didsbury, Stockport, South Manchester and Manchester Airport,
Trafford Park and Lowry Spur came as exciting news, providing
excellent opportunities to become involved in one of the biggest
surveying contracts in this country in recent times.

After
a successful tender bid, N D Oliver & Co Ltd were commissioned
to undertake the contract and have just completed a full topographical
survey of all the additional routes ( over 70 kilometres of proposed
track ) including an aerially plotted context strip.
We produced elevation drawings for all existing over and under
bridges along the route with accompanying digital images and then
linked this information to the topographical survey using AutoCAD
Maps' attachment capabilities.
A digital
video survey showing the full length of all the routes included
in the topographical survey, background orthogonal and oblique photographs
were also produced.

MERSEYTRAVEL – TRAM SYSTEM
Following
the success of the Manchester Metrolink Phase III Extension
and Merseytram line 1 we were
awarded the contract to undertake a full topographical survey for the
initial phase of the proposed Merseytram line 2.
The
project was broadly similar to that of Merseytram Line 1 and covered 16
kilometres of existing highway plus small industrial areas with aerial photography
included. The survey
was completed to the client’s satisfaction and the scheme is now
moving through planning.

DEPARTMENT OF WORKS AND PENSIONS – PROJECT TIES
Our client
was instructed by the DWP to undertake a Due Diligence exercise on
approximately 1100 properties in connection with the proposed
privatisation of the Employment Service Estate.
The
exercise required a package of information to be provided for each
property including Nett Internal Area (NIA) surveys, condition
surveys, photographs, location maps, spreadsheet NIA summaries and on
529 properties full CAD floor plans.
We
initially assisted our client with his tender, providing costs and
proposals on the measured survey aspects of the work. The tenders
were submitted, assessed and the contract awarded to our client within
a two week period.
As usual
the timescales for the work were extremely challenging with the whole
project to be completed in six months.
As well as
undertaking 685 NIA surveys and 422 full CAD surveys ourselves, we
provided specification, samples and advice to the other survey
contractors working directly for our client. Due to the timescales we
employed another eight survey companies in subcontract roles and in
fact they did a large proportion of the work with ourselves managing
the project, and checking data and producing final reports.
The
following were produced for each property:
-
NIA line
diagram (with ITZA zoning)
-
Spreadsheet summary of area and other relevant details
-
Internal
and external photographs
-
O. S.
location map
-
Full CAD
floor plan (optional)
All the
data for the project was produced in digital format and submitted to
our clients website in a rolling program. All the other parties
involved in the project were allowed access to the website and could
therefore download data as soon as it became available.
In
summary, we provided NIA packages of data for approximately 6.0
million sq ft and full CAD floor plans of approximately 5.5 million sq
ft. The project is ongoing and our data is in use by a variety of
architects, consultants and surveyors throughout the country.

THE
MERCADO COMPLEX, LEEDS
We were
commissioned to undertake a full topographical survey and measured
building survey of a 28,00 square metre warehouse complex, prior to
relocation.
Once the
main framework of the control points had been observed instrumentally
a large amount of good old fashioned tape measuring was involved due
to the restrictions imposed by the stored material. Detailed section
drawings showing the layout of the roof trusses were also provided
along with a roof plan and 1.2 km of elevations. |

|
PUBLIC HOUSE SURVEYS
Under new licensing regulations public houses will have to provide more detailed information on their
premises. We have
recently completed surveying of 65 public houses (part of a 700+
chain) to provide this required data.
The
specification and presentation of the floor plan surveys were tailored
to suit the requirements of the new legislation an included plotting
locations of seating, fire safety equipment, drinking areas, games
machines and many other usual relevant details.
Drawings were provided as fuller layered AutoCAD drawing files
and submitted to the client in a rolling program.
