Our role on energy & power projects.
Mattis supports integrated scheduling and reporting tailored to project delivery methods, contract requirements and available technical expertise.
- 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.
Utility interfaces
Interconnection, utility works and third-party approvals are often outside the project team’s control and need careful tracking.
Outages
Planned outages have fixed windows. Missing one can push work out by weeks or months.
Equipment procurement
Transformers, turbines, inverters and other major equipment have long lead times and strict delivery logistics.
Commissioning and milestones
Testing, energization and commercial operation milestones are tied to contractual and commercial obligations.
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 energy & power teams.

Integrated Master Scheduling
One coordinated view of design, procurement, construction, systems integration and turnover.

Integrated Project Controls
Connect schedule, progress, cost and risk into one consistent view of performance.
Explore →
Critical Path Analysis
Understand what truly drives completion: driving logic, path continuity, constraints and float.
Explore →
Delay Analysis
Technical schedule analysis that explains what happened, why, and what it means for completion.
Explore →How do you treat outage windows?
As fixed constraints with readiness logic planned backwards from each window, so the risk of missing one is visible early.
Can you integrate third-party utility schedules?
Yes. External milestones can be represented with interface logic and tracked in every update.
