Common excavation problems:
- Improperly marked or hidden utility lines
- Forgotten building remains and construction debris
- Unexpected groundwater
How experienced contractors solve site challenges:

- Performing underground image scans and using test pits to identify buried artifacts
- Combining historic and real-time groundwater data to develop a custom water management plan
Common Excavation Problems and How Experienced Contractors Solve Them
Excavation is the first and most important step in your residential or commercial construction project, setting the stage for a stable foundation. But no two sites are alike, so challenges should be expected. Among the most common are:
Improperly marked or hidden utility lines
Striking unmarked utility lines during excavation happens fairly often because of outdated or incomplete maps and documents, as well as utility-marking errors.
Buried debris
It's not uncommon for our groundwork contractors to unearth long-forgotten building remains, abandoned septic tanks and cisterns, utility pipes, construction materials, yard waste and other debris during land clearing and excavation.
Unexpected groundwater
Water can disrupt excavation like nothing else, undermining site integrity and increasing the likelihood of trench collapse, equipment and foundation damage, and work delays.

How Our Excavation Team Prevents Groundwork Mishaps
Our groundwork team understands the importance of proper planning and preparation before digging. Here is how we handle each problem.
Identifying marked or hidden utility lines
Following up a call to 811, the national call-before-you-dig program, with a ground-penetrating radar scan helps our contractors avoid hazards and delays caused by water, gas and electrical lines.
Surveying for buried artifacts
Underground imaging and test pits (small, strategic digs) let us identify anomalies before they lead to damaged equipment and unexpected waste-disposal work that inflates project timelines and costs.
Researching and planning for water management
Hydrological surveys, real-time groundwater assessments and test pits help us safeguard your site and put the best combination of water management, soil stabilization and erosion control measures in place against current and future water damage.
