A-11 Transport of construction workers – screening and simplified LCA

Aspect A-11 Transport of construction workers – screening and simplified LCA
Description
This aspect concerns the transportation of construction workers from home to work and to the construction site. Under specific goal and scope, this aspect might be interesting for, say, a construction company that needs to identify the hotspots of its construction site.

Provisions The transport of construction workers may be included in screening and simplified LCA if it is 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).Transportation of workers to construction site may be included for screening and simplified LCA if it is in the focus of the study. Refer to cut-off rules, and use default values (such as ratios).
Rules from:
EN 15978No specific rule is defined (8.5 Scenarios for the construction process stage (Modules A4–A5))
Guidance
The practitioner should use default values (generic data, ratios) for simplified LCA. Such data can be defined with stakeholders.This aspect may be neglected for most building LCA studies, because it may fall outside the goal and scope. However, specific building stakeholders, such as construction companies, may have a special interest and thus will take it into account.If taken into account, this aspect is likely to fall under cut-off-rules for most construction projects. Such a statement should be supported through detailed studies of the construction stage. It will be revised if more evidence is available.
