LandScope Engineering have developed versatile solutions that address the challenges of bridge surveys and inspections. LandScope Engineering provides the capability to acquire high resolution LiDAR, photography, SoNAR and RaDAR from a number of methods which are best suited to the type of bridge, the bridge span and the location.

High Resolution LiDAR and Photography SolutionsLandScope is able to offer both terrestrial (static) based laser scanning and photographic system or a mobile mapping based solution. In each case the LiDAR and photographic datasets are accurately geo-referenced to ensure maximum possible value is derived by end users. Combined with total stations the terrestrial laser scanning may be used to provide the highest order of measurement accuracy in bridge modelling. The autoMAP mobile mapping system deployed on a small survey craft or RIB offers the ability to acquire LiDAR and photographic datasets in less accessible areas e.g. in and around piers, bridge undersides etc.

Applications include:• Movement monitoring• Visual condition assessment• Underwater sonar imaging• Scour assessment and condition survey• 3D modelling• Void mapping• Structural element survey

eSoNAR SolutionsBelow the waterline LandScope offers various sonar based technologies which may be readily integrated to top side survey and provide compelling high resolution deliverables as part of bridge survey and inspection programmes. 3D sector scanning sonar systems provide under-water point clouds from fixed survey positions whereas multibeam swath bathymetry systems provide high resolution datasets from a mobile survey platform. Additionally, traditional sidescan sonar and single beam echo-sounders may also be deployed.

RaDAR solutionsLandScope Engineering specialise in non destructive investigation using best available technology based primarily on ground penetrating radar to survey a wide variety of structures.

Our structural imaging services utilise the latest radar technology to accurately map out a wide variety of buried and covered features. As a Non-Destructive Testing technique it is assured that no damage will be inflicted upon the structure. The signal emitted from the radar is able to penetrate a wide variety of materials including concrete, stone, tarmac, wood, and many more. There are numerous applications for which non-destructive structural imaging may be used in bridge survey and inspection, including:

• Rebar location and mapping • Slab thickness measurement • Location of structural beams • Void Mapping • Retaining wall integrity assessment • River and sea defence analysis • Structural element mapping
