Core SUE Services:
•Utility Background Research
•3D Subsurface Mapping
•Ground Penetrating Radar
•Vacuum Excavation Services
Initial Cost: SUE costs average about 2% of a project’s total budget.
Example of Cost Savings to V&M Client:
City of Greenville, SC – West End Wastewater Project
• Actual Construction Cost – $20,000 under budgeted cost
• Construction Time Period – 20% ahead of schedule
“If we had encountered these utilities or the amount of granite that needed to be removed after the project had begun, rather that pre-planning for them, then the $750,000 project could have easily turned into a $1.5M or $2M project.
- Matthew Maxey, PE, the superintendent of Wastewater Operations, City of Greenville, SC
Subsurface utility engineering (SUE) provides time and money-saving information, providing essential information and storing it in an ever-living database. Information gathered by SUE specialists detail highly accurate mapping of existing underground utilities in three dimensions. So, rather than “finding out the hard way” that plotted utility information was inaccurate, large projects save time and money using this cutting edge technology. It takes the guesswork out of groundwork.
Our SUE experts begin with researching available utility records. Then, utilizing the highly precise, UTILOCATOR, our experts find and paint the utility at the ground’s surface. A vacuum excavator locates and exposes all utilities in both horizontal and vertical planes for extreme accuracy. Loosened soil and rock are then removed from the hole by the vacuum. This excavates a 12”x12” hole, as deep as required, to safely expose the buried utility.
Advantages of SUE
Knowing the exact location, including the depth, of underground utilities is critical to both design & construction. Previous to today's groundbreaking technology, utilities were often poorly documented, hard to find, potentially dangerous, as well as being serious time and money wasters.
Reducing cost & time to expose utilities
Reducing risk of damage to the utility during the location process
Avoiding costs & damage of conventional location process
Reducing utility location costs
Reducing costs of plan revisions
Coordinating utility relocation before construction begins
Avoiding project delays & construction change orders for utility conflicts
Reducing damage claims and risk of potentially lethal injuries
