Multi-package infrastructure delivery distributes scope across many contracts, which distributes float in ways nobody owns. On the programs we support, the majority of critical delay traces to interface events: late access, incomplete predecessor scope, or systems requirements discovered during commissioning.
Interface risk responds well to structural treatment. Mapping interfaces explicitly, assigning each an owner and a date, and integrating them into the master schedule as tracked constraints converts a coordination problem into a controls problem.
Programs that treat commissioning and systems completion as a planning input from day one consistently outperform those that treat it as the last phase of construction.
What we recommend
- Register every inter-package interface with an owner, date and dependency.
- Plan systems completion and closeout requirements from initiation.
- Simulate access and logistics in 4D before mobilisation.
