Scheduling for Mission-Critical Delivery.
Data center projects demand careful coordination of design, long-lead electrical and mechanical equipment, building construction, energization, commissioning and phased turnover.

Our role on data center projects.
Mattis supports milestone-driven planning, procurement integration, trade sequencing, system readiness, commissioning logic and schedule reporting to help teams maintain visibility across critical interfaces.
- 01
Define milestones and interfaces
Agree the milestones that matter and map the interfaces between design, procurement, construction, systems and turnover.
- 02
Establish construction-driven logic
Build sequences from how the work will actually be done, with the people who will do it.
- 03
Monitor procurement and execution
Track long-lead items and field progress against the plan in every update.
- 04
Identify critical and near-critical paths
Know which activities drive each milestone and which could take over.
- 05
Communicate schedule risk clearly
Reporting that tells field teams and executives what is changing and what to do next.
The interfaces that decide the finish date.
Complex phased energization
Permanent power often arrives in stages. Each data hall depends on the right switchgear, transformers and utility feed being energized in sequence.
Long-lead electrical equipment
Switchgear, generators, UPS and transformers can have lead times longer than the building programme, so procurement frequently drives the critical path.
Integrated systems testing
Commissioning progresses through levels, from factory witness tests to integrated systems testing. A failed test can cascade through everything after it.
Operational readiness
Ready-for-service dates link construction to customer commitments and revenue, so turnover must be planned as carefully as construction.
From notice to proceed to handover.
Click any milestone to see what we watch. Sequences vary by project; this is a representative path.
What teams typically receive.
Baseline or integrated master schedule
A logic-driven plan structured around this market's milestones and interfaces.
Progress update narrative
A clear explanation of progress, variance and outlook each period.
Milestone dashboard
The milestones that matter, with forecast, variance and trend.
Schedule review
An independent check of schedule quality and realism.
Recovery options assessment
Tested options when key milestones are threatened.
Every construction market has distinct interfaces, risks and delivery requirements.
We adapt our planning and controls approach to the technical and commercial realities of each project.
How we help data center teams.
Integrated Master Scheduling
One coordinated view of design, procurement, construction, systems integration and turnover.

Schedule Health Assessments
An independent review that finds schedule weaknesses before they become delivery risks.
Explore →Can you schedule multiple data halls in phases?
Yes. Phased programmes are structured so each hall or phase has its own path to energization and ready-for-service, with shared infrastructure linked across phases.
How do you treat commissioning in the schedule?
As logic-driven sequences tied to the systems they test, from factory witness testing through integrated systems testing, rather than a lump at the end.
