The accuracy and simplicity of the geospatial data technology and solutions Laing O’ Rourke has been using as part of their contract with Severn Trent Water, has saved the company both time and money on the project to collect data on new and existing water mains and fittings.
The equipment, which was supplied and is supported by MGISS, is being used on a daily basis. Laing O’ Rourke has implemented the ProMark 220 and Digiterra workflows and had training from MGISS in order to do this.
Locating assets, such as new and existing water mains and fittings, have historically been hard to find as the accuracy cannot be pinpointed within a close enough range using OS maps and pen and paper. Very often this results in more time and money being spent to find the correct location whilst avoiding hitting other services running next to the water supply.With the ProMark 220 and Digiterra workflows in action, once the data is collected on site, it is then downloaded and a scale drawing created through the CAD mapping system. This shows the X, Y coordinates and fitting details, to produce an ‘As Built’ record. This is then sent to STW who use it to update their records.
This accurate records system allows Laing O’Rourke to offer the client confidence they are able to locate assets quickly consequently saving them time and money. It means less revisits to site and less time spent in the office and comparing readings with drawings and site sketches. They are confident the drawings are right first time.
Peter Colquhoun, an Aslaid Technician for Laing O’ Rourke Infrastructure said:
“STW has been delighted with the progress so far. The accurate drawings our equipment produces means the client can take them to site and quickly and efficiently locate them. It is allowing us to achieve much more in a shorter timeframe.
The technology reduces the risk of compromising other services in place whilst digging to locate and allows quick identification and assessment of any leaks thus cutting the time customers are without water.
The training carried out by MGISS on site was really beneficial both to those using the ProMark and to the team in the office downloading it and producing the As Built drawings. The training has given us the knowledge and the confidence to tailor the outputs in-house to suit our requirements. We have found MGISS very easy to work with, nothing is too much trouble.”
Laing O’ Rourke is also starting to use the technology in upfront surveys to locate existing water fittings and other utilities. It is also making a saving by taking levels on site using the ProMark 220 when in the past the company has had to employ other parties to do this work.
Laing O’ Rourke are continuing to use this type of technology in the future and are currently looking to utilise the MGISS technology further by adapting the way it, and the company’s GIS packages interact, to create a more intelligent ‘As built’ solution.
