Recent requirements to enhance gas asset management data at National Grid meant it was necessary to obtain Laser Scanning equipment in order to support the capture of detailed asset data.
The data capture is managed through an internal project as part of a larger business improvement programme, which will allow National Grid to fulfil requirements such as the development of a more targeted schedule for gas asset maintenance and replacement work.
Various options for asset capture and recognition were considered for use in 3D modelling, including basic photogrammetry. However it was decided that laser scanning output provides a more operationally valuable and accurate model at the same time as high quality collection of asset data and condition.
The FARO X130 Laser Scanner and the NCtech iSTAR Panoramic Camera were first choice as the two instruments work in conjunction to provide colourised 3D point clouds and 360-degree images of the scanned area.
The instruments are on long-term hire from Opti-cal for a total of 70 weeks. The package also includes 16-days of scanner/camera training, which will allow the deployment of the equipment by blended teams of Operational and Project staff team nationwide to utilise the equipment to its full potential.
