Interim Contract Manager for Capital Projects and Operations

Senior contracting and procurement capacity from the early project phase through execution and operations. Short or long term, part-time or full-time.

In an interim role I take ownership from the first day, as part of the team rather than alongside it, without losing sight of what the organisation needs after I leave. I pay particular attention to the early phase: it is often under-resourced, while this is where the most important contractual choices are made.

Ernst Rietmeijer

Experienced Capacity at the Moments That Matter

Early phase

Capacity before the organisation is in place

Contract strategy, package structure and tender documents are needed while budget and a contracts function are not yet in place.

Tender & award

Critical project phase

A project enters tendering, award or execution without senior capacity for contract management, changes and claims.

Any phase

Sudden vacancy

A key contract manager leaves mid-project: continuity is needed quickly in contract management, changes and claims.

Execution

Turnaround or shutdown

Dedicated contracting and contractor coordination for a turnaround or shutdown.

Operations

MRO contract renewal

Existing maintenance contracts need restructuring around performance and cost efficiency.

Any phase

Independent review

A contract strategy or tender approach needs an independent check before a key commitment.

The Right Interim Role for Each Phase, from Early Phase to Operations

From contract strategy in the early phase to supplier performance in operations: the interim role follows the phase the project or asset is in.

FEL 3 & ExecutionInterim Contract ManagerTender and firm prices before the investment decision; award, contract management, changes and claims
Execution & OperationsInterim Procurement ManagerSourcing, MRO contracts, framework agreements and supplier performance

In most capital projects the main contracts are tendered in FEL 3, so that firm prices and a fixed budget support the investment decision (FID). Award and contract management follow in execution. Each role can be filled part-time or full-time, for a single phase or across several.

Deliverables in Each Area

Four areas in which contractual and commercial choices shape outcomes, each with concrete deliverables for the project or organisation.

Early phase

Early Phase Contract Strategy & Procurement Readiness

In the early phase of a project, budget and organisation are often not yet in place, while this is exactly when contract strategy, scope allocation and market approach are decided, before FID or any other investment decision. Bringing senior capacity in early helps the project reach procurement readiness before execution risk is locked in.

Deliverables
  • Contract strategy
  • Package and interface matrix
  • Risk allocation principles
  • Procurement roadmap
Execution

Project Contracting & Contract Management

Mid-sized and major projects alike depend on sound tender execution, commercial alignment and disciplined contract structures. Senior support strengthens project organisations in the phases in which contract structures are set.

Deliverables
  • Tender plan and evaluation framework
  • Commercial bid comparison and negotiation
  • Contract management during execution
  • Change and claim management
Operations

MRO Strategy & Contract Optimisation

In operational environments, the challenge is less about building new structures and more about improving what already exists. The focus is on aligning maintenance and procurement around a clear, workable strategy.

Deliverables
  • Contract assessment
  • Supplier model
  • KPI framework
  • Improvement roadmap
Governance

Contract Governance & Commercial Frameworks

Supporting organisations in developing and strengthening the contractual frameworks that underpin consistent procurement and supplier management, including contract documentation, procurement procedures, supplier evaluation frameworks and governance models for framework agreements and long-term service contracts.

Deliverables
  • Approval matrix
  • Procurement procedures
  • Contract templates
  • Supplier review framework
