A-08 Land preparation and earthwork during the construction process – complete LCA

Aspect A-08 Land preparation and earthwork during the construction process – complete LCA
Description
This aspect relates to the impact of site preparation, including the fuel consumption of, for example skid-steer loaders or bulldozers during the groundworks and landscaping. Under the specific goal and scope, this aspect might be interesting for, say, a construction company that needs to identify the hotspots of its construction site. Should the land preparation and earthwork during the construction process be considered in the context of a complete LCA?

Provisions The land preparation and earthwork should be included in complete LCA if they are relevant for the goal and scope of the study (e.g. a construction company might have more interest than a building designer in this aspect).
Rules from:
EN 159787.4.3 Boundaries of the construction process stage

8.5 Scenarios for the construction process stage (Modules A4–A5)

According to the rules from EN 15978, the system boundary for the construction process shall include the groundworks and landscaping

Guidance
The practitioner should use detailed calculation (based on specific  data) for complete LCA. The impact of land preparation and earthwork can be assessed using generic data accounting for the impact of the fuel consumption of construction machinery (e.g. skid-steer loaders or bulldozers).This aspect can be neglected for most construction projects, as it is of minor relevance.
