A critical aspect to the project was to ensure that there would be no interruptions to customer operations throughout construction. All the work entailed coordination of critical shutdowns and tie-ins. DPR and the project team generated detailed Methods of Procedure (MOP’s) and coordination maps to clearly communicate all work onsite. Challenges also included working within occupied mechanical and electrical yards that had limited laydown and access. The project was completed in multiple phases so the total capacity and redundancy of N+1 was always maintained for the tier 3 active data center.
