About the programme
Course Overview
Splitting a large project across multiple contractors reduces single-supplier risk but creates a new one: work that falls between packages, at boundaries no single contract fully owns. An interface is any point where the output of one contractor depends on the output, timing or information of another, and unmanaged interfaces are a leading cause of rework, disputes and schedule slippage on multi-contractor projects. This course sets out a complete interface management method: identifying physical, organisational and technical interfaces early, documenting them in an interface register and formal interface control documents, and governing resolution through joint interface committees rather than leaving contractors to negotiate boundaries informally. Participants work through the tools that make interfaces visible across parties, including interface numbering conventions and dashboard reporting of open and overdue items, and follow the process through to physical close-out, punch listing and the lessons that should shape how the next project is packaged and contracted.
Expected Learning Outcomes
Build an interface register that assigns a single owner and due date to every interface.
Draft an interface control document that both contracting parties can sign off against.
Chair a joint interface committee that resolves boundary disputes between contractors.
Prioritise interfaces by the consequence of late resolution rather than by raise date alone.
Track interface closure through dashboard reporting that exposes ageing and overdue items.
Close out interfaces at commissioning with verified as-built records against the interface control document.
Who Should Attend
Interface managers and coordinators appointed on multi-contractor capital projects.
Project managers overseeing packages delivered by more than one contractor.
Engineering leads whose systems or structures connect physically to another contractor's scope.
Contract administrators drafting interface obligations into contractor scopes of work.
Commissioning managers responsible for verifying interfaces before system handover.
Client-side project controls staff monitoring interface status across a project portfolio.

01Foundations of Interface Management on Complex Projects
2 sessions · 8 points
Session 1Defining Interfaces and Where They Arise
- Classify interfaces as physical, organisational, technical or contractual before assigning ownership.
- Identify battery limits and tie-in points between adjoining contractor packages.
- Explain why fragmented contracting increases interface risk compared with a single main contractor.
- Run an early interface identification workshop with all contractors shortly after award.
Session 2Governance Structure and Roles
- Define the interface coordinator's mandate and authority relative to individual contractors.
- Distinguish the interface owner from the action party responsible for closing an item.
- Set up a joint interface committee with representation from every affected contractor.
- Design an escalation path to the project steering group for interfaces that remain unresolved.
02Tools and Documentation for Interface Control
2 sessions · 8 points
Session 1The Interface Register and Interface Control Documents
- Design an interface register with fields for description, parties, due date and current status.
- Draft an interface control document that states technical parameters both parties must meet.
- Apply version control to interface control documents affected by later design changes.
- Link each interface's due date to the corresponding milestone in the master schedule.
Session 2Digital Interface Management Systems
- Select an interface management tool that gives every contractor visibility of shared items.
- Set a numbering and cross-referencing convention that stays consistent across all packages.
- Build dashboard reporting that shows open, closed and overdue interfaces by contractor.
- Maintain an audit trail of interface decisions for later reference during disputes.
03Running the Interface Process Day to Day
2 sessions · 8 points
Session 1Interface Identification and Risk Assessment
- Run structured interface-hunting workshops across disciplines rather than waiting for issues to surface.
- Assess interface risk by the consequence of late resolution on safety, cost or schedule.
- Prioritise safety-critical and schedule-critical interfaces ahead of lower-consequence items.
- Align interface close-out dates with the construction or installation sequence on site.
Session 2Resolving Conflicts and Change at Interfaces
- Assess how a design change on one contract ripples across interfaces into another contractor's scope.
- Mediate disputes between contractors over which party owns a disputed interface.
- Manage third-party interfaces with utilities, adjacent operators or public authorities.
- Apply the contractual mechanism that governs interface-related claims and cost recovery.
04Closing Out and Learning from Interfaces
2 sessions · 8 points
Session 1Interface Close-Out and Commissioning Readiness
- Conduct a physical interface walk-down and punch list before system handover.
- Link interface completion certificates to the wider system handover and commissioning plan.
- Verify that as-built conditions match the signed interface control document.
- Confirm interface readiness as a precondition for energisation or start-up.
Session 2Measuring Performance and Capturing Lessons
- Track interface KPIs including ageing, closure rate and reopened items across the project.
- Run a post-project lessons-learned workshop focused specifically on interface performance.
- Feed interface lessons into how the next project's work is packaged and contracted.
- Benchmark interface closure performance across projects to identify recurring root causes.
