Time saving in a hand-off
Based on a 2022 process-management study. The time saving is an estimate in the proposed future-state process, not a verified result. No realised performance improvement was measured.

Context
At A.Hak's Doetinchem branch, work preparers arrange KLIC notifications while preparing excavation work packs for underground infrastructure projects. The notification helps identify existing cables, pipes and other site risks before crews begin work.
Project scope
The study focused on the KLIC notification within the work preparation process for the solo pipeline department, rather than the entire construction project lifecycle.
Why it matters
Incomplete drawings, missing information or unresolved precautionary requirements can delay the work pack and leave excavation crews without a clear picture of site conditions.
