A-07 Land preparation and earthwork during the construction process – screening and simplified LCA

Aspect A-07 Land preparation and earthwork during the construction process – screening and simplified 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 screening or simplified LCA?

Provisions The land preparation and earthwork may be included in screening and simplified LCA if they are relevant to 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 15978
7.4.3 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 default values (e.g. ratios or generic data) for screening and simplified LCA, and also refer to cut-off rules. Ratios can be defined with stakeholders. This aspect can be neglected for most construction projects, as it is of minor relevance.
