What do the limits of excavation for a contractor define?

• A. Site boundaries
• B. Neat Line
• C. Geotechnical Limits
• D. Security Perimeter

Answer: (B)

The limits of excavation for a contractor are defined by the neat line. This term refers to the designated edges of an excavation site, indicating where the excavation work is to begin and end. Neat lines are critical in construction because they clearly define the area to be excavated, ensuring that excavation activities stay within the specified parameters of the project. This helps in avoiding over-excavation, which can lead to unnecessary costs and potential structural issues.

While site boundaries outline the overall limits of the construction site, the neat line is more specific and directly related to the excavation work itself. Geotechnical limits refer to the depth and types of materials involved in excavation as determined by geotechnical studies, which do not define the physical limits of the excavation area. A security perimeter pertains to the safety and security of the construction site, ensuring that unauthorized individuals do not access the area but does not relate to the defined limits of excavation work.
