Excavation & Earthwork Quantities
Cut/fill, bulkings, disposal vs import—introductory notes for earthworks measurement.
Measurement notes
Define whether volumes are in situ, loose, or compacted. Bulking factors affect haul and disposal costs.
Strata assumptions drive method; geotech reports should align with BOQ descriptions.
Split bulk excavation, trenching, and pit excavation if rates differ; benching and batter slopes change volumes versus simple prisms.
Disposal vs reuse
On-site stockpile, off-site disposal, and import fill are different cost lines—quantities and haul distance assumptions must match.
Contaminated or hazardous material needs separate classification and often measured by weight or truck loads.
Temporary works interaction
Shoring, dewatering, and sheet piling may be preliminaries or measured items—read the preamble.
Working space around excavations affects plant choice; that can live in method-related charges rather than m³ lines.
