Commercial Projects
High Precision, Large Scale
-
Larger Scale:
Commercial projects usually involve large, complex sites, such as office buildings, industrial complexes, shopping centers, or multi-story developments. These sites often cover a large area and may have multiple utility systems running in different directions and at varying depths.
-
Multiple Utility Systems:
A commercial project may involve multiple utility systems (water, gas, electricity, telecommunications, sewer, etc.), often with overlapping and sometimes conflicting infrastructures. As a result, more extensive utility locating (including QL-B and QL-A) may be required to ensure accuracy and prevent conflicts during construction.
-
Higher Need for Detailed Mapping
Commercial projects often require detailed utility maps and verification due to the complexity and potential for utility conflicts during construction. QL-A (the highest level of utility location accuracy) is more common in commercial projects, especially in urban or high-risk areas.
Residential Projects
High Precision, Small Scale
-
Smaller Scale
Residential projects tend to be smaller in size, such as single-family homes, small multi-family buildings (duplexes, townhouses), or residential subdivisions. The area being surveyed is typically much smaller, and the number of utilities involved is fewer and more predictable.
-
Simpler Utility Systems
Residential developments usually have more straightforward utility networks (water, gas, electricity, and sewage), often running in established public easements. The need for advanced locating methods is generally less critical.​
