I M & L provide asset location, concrete scanning,condition reports all provided in GIS format complete with GPS co –ordinates. This information can be provided in autocad or similar.
 
located assets can be laid onto existing survey drawings, Google Mapping or Deptarment of lands satellite imagry and can incorporate photos and brief comments if required. For the identification of buried assets I M & L Provide site investigation, asset capture, detection and mapping to suit asset managers and consultants requirements
The locating service provides critical information for:
- asset owners OH & S Information
- site redevelopment
- site acquisition technical due diligence
- construction planning + project management
- in conjunction with environmental or geotechnical surveys
- alterations and additions to existing structures
If site plans are not available for the property I M & L are able to undertake a site survey to determine property boundaries and the building footprint. All plans are created electronically to allow the mapping of the underground services and utilities. In addition to the services mapping a visual site assessment is undertaken to provide an analysis of the specific site conditions. This analysis identifies any relevant features that might affect the underground services/utility and proposed works.
Please review our Methodology for more detail INFRASTRUCTURE, MAPPING & LOCATING, DETECTING © METHODOLOGY
State of the art technology is used to undertake the underground investigation. The procedures are non invasive and non destructive to the property. However should further investigation be required following the survey of the site some excavation may be undertaken. All equipment used during the survey is safe for both the operator of the equipment and the property tenants.
VISUAL SITE ASSESSMENT
----------------------------------------------------------------------------------------------------------------------
Prior to the commencement of any investigation works on site a thorough visual site assessment is undertaken. This assessment identifi es any limitations or conditions that may affect the survey.
FERROMAGNETIC DETECTION
----------------------------------------------------------------------------------------------------------------------
A metal detector is used in the primary stages of the investigation to provide a quick ‘snap shot’ of the underground services/utilities on site. The detection device used has a wide range visual meter, along with a concurrent audible tone which indicates the edges and size of buried magnetic objects. Precise calibration eliminates false readings and rejects non- magnetic objects. The equipment is water resistance and can be used to probe mud.
APPLICATIONS FOR A FERROMAGNETIC DETECTOR INCLUDE:
- Ferrous objects
- Valve boxes
- Manhole, hydrant or valve cover
- Buried curb stops
- Rebar or studs in building structures
INFRASTRUCTURE DETECTION, MAPPING & LOCATING © CONDUCTIVE CABLE/PIPE LOCATION AND DEPTH
----------------------------------------------------------------------------------------------------------------------
A triple frequency line locator is used to locate and determine the depth of services that are housed in a conductive cable or pipe. These services generally include telecommunications and power. With a single button push this equipment is able to provide depth measurement to the centre of a pipe down to 600cm.
OTHER FEATURES INCLUDE:
- It is distance sensitive with left/right visual and audio guidance
- Current measurement indicates when you stray to another pipe or the pipe has forked
- Ability to trace Sondes, electric cables, cables and tracer wires
- Able to transmit three active frequencies
GROUND PENETRATING RADAR (GPR)
----------------------------------------------------------------------------------------------------------------------
 GPR is an underground imaging technology using radio waves to record many both natural and man-made features buried under the ground. The equipment is portable and controlled by an on site computer system. The operator is able to view and assess the results in real time on site. The GPR can detect all material types, both metallic and non-metallic, including plastics, concrete, ceramics and asphalt composite. The data obtained in the field provides the user with the location of cables, pipes, duct banks, conduits or depth to bedrock.
FIBRE OPTICS
----------------------------------------------------------------------------------------------------------------------
A GPR survey is able to locate non-conductive pipes. These underground pipes generally include fibre optics, sewer, stormwater pipes and water filled poly lines.
UNKNOWN SITE CONDITIONS
Also a GPR survey is required when a thorough investigation of the site is required. The equipment is able to provide information regarding unknown underground site conditions including:
- previous construction works on site such as old footings that have been concealed;
- voids due to backfilling
- foundation material and any differences in fill on the site
- redundant storage tanks
- buried waste

GPS ( Global positioning Systems )
----------------------------------------------------------------------------------------------------------------------
The use of GPS technology will play an ever increasing role in the management of infrastructure and can be used to provide coordinates for the location of services and assets both above the ground and below.
Furthermore GPs co-ordinates can be plotted onto the drawings with specific information added to each co-ordinate that indicates either the status of the asset or any changes in direction of the underground asset. For example we can supply co-ordinates for all fire hydrants on any given site and comments can be added as to the condition of the asset.
