$3M CAPEX Savings by early constraint identification

---

A large chemicals and energy company was executing a complex MegaProject involving the construction and start-up of multiple inderdependent chemical facilities. Commissioning activities required reliable access to utilities such as natural gas, steam, nitrogen, instrument air, and other site services, all of which needed to be available at the right time to support safe and efficient startup.

While a detailed construction schedule existed, the project lacked a clear, integrated view of when commissioning teams would actually need utilities versus when those utilities would be available based on construction progress. This misalignment created a significant risk of idle commissioning teams, rework, and schedule delays — each carrying substantial cost on a MegaProject scale.

Conducted structured interviews with commissioning teams across multiple process units to develop realistic, time-phased demand profiles for each major utility. These predicted consumption curves were mapped against the construction schedule to identify gaps where utility availability would fall short of commissioning needs.

By overlaying commissioning demand with construction progress, the analysis highlighted specific schedule conflicts and resource misallocations. This allowed the project owner to re-prioritize construction activities, shift resources to critical utility systems, and streamline the overall execution sequence.

The integrated schedule enabled earlier utility readiness, eliminated commissioning delays, and reduced unnecessary downtime. The refined plan shortened the overall project schedule by seven days, avoiding approximately $3M in projected MegaProject costs while improving coordination between construction and commissioning teams.
