Subsurface Utility Engineering Services Gaining Momentum in Ontario
An accurate survey of surface features is an integral part of almost every construction project. These are features that can easily be seen with the naked eye. Why then are features that can't be seen ignored when they can cause cost overruns, delays, and safety concerns? With exception of picking up any valves and pedestals that give us only a rough idea as to their location, the position of utilities such as gas lines, telephone ducts, hydro cables, and watermains are usually ignored. Instead common practice is to rely on old maps and as-built drawings that may or may not reflect the true conditions that exist underground.

Proactive Utilities Management in Public Private Ventures: Plaguing the overwhelming number of projects dedicated to servicing and updating the nation’s aging and increasingly congested infrastructure, the seemingly unavoidable delays due to utility complications continue to retard progress and emaciate already tight budgets. Subsurface Utility Engineering, the branch of engineering that specializes in utility identification, location, and advising, is quickly becoming the modus operandi for transportation departments nationwide. It is over twenty years old and yet no organizational system has been widely applied to harness the full potential of Subsurface Utility Engineering. Conflict analysis is an organizational tool for Subsurface Utility Engineering. Working with utility companies, designers, transportation departments, and contractors and employing a powerful new data management tool, the Conflict Matrix, conflict analysis provides a greater sense of coordination. Utility Coordination is becoming a more prevalent service within the design build / PPV arena. Performing utility relocations as plans develop, presents many challenges to utility owners. Utility owners prefer to have complete plans to accommodate relocation efforts. This issue presents a challenge to utilities that typically relocate for projects in a design-bid-build environment. As PPV and PPP ventures look to minimize risk associated with firm fixed pricing contracts, innovative ideas in project delivery with respect to utility conflicts are becoming increasingly important. The coalescence of Subsurface Utility Engineering and conflict analysis, though a young concept, is beginning to reshape the industry. With this intimate connection, data transmission and management work in tandem, resulting in very little data loss and confusion. Higher data efficiency in turn propagates fewer missed conflicts. The potential of savings becomes obvious. By merging symbiotically to become one integrated entity, Subsurface Utility Engineering and conflict analysis form the nexus of proactive utilities management that efficiently reduces needless utility relocations, minimizes utility complications, and diminishes overall cost.
