Many land development projects end up being short or long, and solving these problems in the late stage of the project may cost a lot of time and money.

• Inaccurate original ground topography
• Incomplete knowledge of what is underground and/or in the ground
• Limited number of topography updates throughout the life of the project
• Inconsistent Soil Types

Design Stage - Designing the site with a balance area to deal with the excess/shortage of dirt helps avoid the off-haul but not long-hauls AND Soil tests from a limited number of borings don't provide sufficient data to predict the behavior of dirt during grading

Construction Stage - Aerial or conventional topos are expensive and time consuming making them impractical to conduct on a regular basis to spot issues early on AND changes in design can ensure that site remains balanced throughout the life of the project.
