Nine cost drivers
Access, soil type, groundwater, buried obstructions, haul distance, disposal class, imported material, required compaction and project sequencing all affect resources. Weather and working-hour limits can compound them.
Reduce uncertainty
Provide surveys, geotechnical information, utility records and clear finish elevations. Identify disposal destinations and testing requirements. Where quantities remain unknown, agree on measurable unit rates.
Read the exclusions
A low total may exclude dewatering, rock, contaminated soil, traffic control, permits or restoration. Compare inclusions and assumptions before comparing totals.
Safety note: Utility locating does not replace safe excavation practice. Requirements differ by location and conditions; use qualified professionals and follow the authority having jurisdiction.
Questions to ask
- What information or assumptions is this plan based on?
- Who is responsible for locates, permits, survey control and inspection?
- What site condition would stop or change the work?
- How are quantities, changes and disposal documented?
- What records remain when the work is complete?
