The Constantine Group's Subsurface Utility Engineering provides a full suite of mapping services which include surface and buried assets. We help the client design a mapping solution based on many factors, but mostly it is based off what they currently have, or in most cases, what they don't have. We can help build the skeleton of the client's system by shooting the surface features with a sub-meter GPS and then use record drawings, system knowledge and experience to build the line work. In some cases, the client needs more accurate data depicted within their GIS which usually means horizontal line verification using a ground penetrating radar or a conductive locating device. Constantine Engineering uses non-intrusive means to locate the buried assets by use of electromagnetic locators and ground penetrating radar (GPR). These means of locating help to prevent damages to the buried utilities by giving us a virtual dig site. In some cases, the client may only want the virtual dig site GPS'd and entered in to the GIS which would make the GIS more accurate than just shooting the surface features. The Constantine Group's Subsurface Utility Engineering can take the whole process another step further by using soft dig technology to verify the top dead center of the buried utility. This method provides the most accurate data by which our field crews would be able to verify not only the size and type of the buried asset but also the depth if desired. The depth is measured from top of buried utility to top of ground using a standard tape measure and entered into the GIS in inches. If the client should want the depth collected in another format such as tenths using a level rod, Constantine Engineering will provide the data to suit. The Constantine Group's Subsurface Utility Engineering is very detail oriented which means that all data collected goes through a rigorous QA/QC process prior to delivery to the client.

Disaster Relief Assistance
Mapping buried assets provides invaluable information before and after natural or man made disasters. Information collected during the mapping process helps managers determine if or when they may need to shut down services in specific areas due to the inherent dangers during and after the disaster. Having the information readily available, the data that mapping provides, disaster recovery is expedited and usually decreases the outage of services measurably. One example of our disaster relief support is after the devastation of hurricane Ivan hit the City of Gulf Port, we assisted in their recovery efforts by locating their buried utilities and mapping the areas that needed isolation valves. This process eased the stress of the utilities managers and workers alike because they now had a place to start. Constantine Engineering is very experienced with disaster preparedness and recovery and is prepared to deploy at a moments notice.
