Subcontractor Management
Project Manager control of subcontractor scope, mobilisation, technical coordination, programme, quality, commercial interfaces, performance and close-out during yacht refit.
OVERVIEW
Subcontractors are central to most yacht refit projects. Their performance can directly affect programme, quality, safety, cost and client confidence. Effective subcontractor management therefore requires more than simply issuing a purchase order and waiting for completion.
The Project Manager must ensure that each subcontractor understands the agreed scope, interfaces, access requirements, technical standards, programme obligations, reporting expectations and commercial controls before work begins.
The objective of this module is to help the Project Manager establish clear subcontractor controls from mobilisation through execution, testing, documentation and final close-out.
KEY RESPONSIBILITIES
• Define a clear and measurable subcontractor scope of work.
• Confirm drawings, specifications, standards and acceptance criteria.
• Verify quotation assumptions, exclusions and commercial conditions.
• Confirm mobilisation dates and programme requirements.
• Identify interfaces with other subcontractors and yacht systems.
• Coordinate permits, access, security and working-area requirements.
• Confirm required qualifications, certifications and specialist competence.
• Review method statements and risk assessments where required.
• Establish reporting and communication arrangements.
• Track progress against the agreed programme.
• Monitor quality and workmanship throughout execution.
• Control changes, additional work and scope growth.
• Prevent unauthorised work from proceeding without approval.
• Record delays, constraints and subcontractor dependencies.
• Coordinate inspections, testing and commissioning.
• Record defects, punch-list items and corrective actions.
• Verify completion documentation before commercial close-out.
• Confirm warranties, certificates, manuals and service reports are received.
• Maintain clear records of decisions, instructions and approvals.
SUBCONTRACTOR CONTROL CHECK
Before mobilisation and during execution, the Project Manager should confirm the following where applicable:
• approved scope of work
• quotation and commercial terms
• exclusions and assumptions
• authorised variation procedure
• programme start and finish dates
• labour and resource requirements
• required materials and long-lead items
• drawings and technical information
• access arrangements
• permits and security requirements
• risk assessments and method statements
• insurance requirements
• certification and specialist qualifications
• interface with other contractors
• equipment shutdown and isolation requirements
• inspection and hold points
• test and commissioning requirements
• daily or weekly progress reporting
• defect and punch-list control
• documentation and handover requirements
• warranty obligations
CHANGE & ADDITIONAL WORK CONTROL
Additional work should not be allowed to develop informally. The Project Manager should ensure that any proposed variation is clearly described, technically justified, commercially identified and authorised through the agreed approval route before significant additional cost is committed.
Where urgent technical action is necessary, the PM should still create a traceable record of the instruction, reason, estimated commercial impact and responsible approving authority.
PROJECT MANAGER COMPETENCY TEST
Scenario 1 — Unclear Scope
A subcontractor arrives onboard to begin work on a deck system. Their quotation refers broadly to “repair and recommission equipment”, but the exact components, test requirements and completion criteria have not been defined.
Question:
What should the Project Manager do before allowing the work to proceed?
A. Allow the subcontractor to begin and clarify the scope later
B. Ask the Captain to supervise the work directly
C. Confirm the scope, technical requirements, interfaces and acceptance criteria before significant work begins
D. Let the subcontractor decide what work is necessary
Reveal answer & rationale
Correct answer: C
Why:
An unclear scope creates technical, programme and commercial risk. The PM should ensure that the required work, responsibilities, interfaces and completion criteria are sufficiently defined before the subcontractor commits labour, materials or additional cost.
Scenario 2 — Additional Work
While dismantling equipment, a subcontractor identifies additional defects and immediately begins extra repair work. The Captain has verbally agreed that the work appears necessary, but no commercial approval has been issued.
Question:
What should the Project Manager do?
A. Allow all additional work because the Captain agreed verbally
B. Stop or control the additional scope until the work, cost and approval route are documented, except where immediate action is required for safety or damage prevention
C. Let the subcontractor decide the final cost afterwards
D. Remove the additional work from the project records
Reveal answer & rationale
Correct answer: B
Why:
Additional work should be technically and commercially controlled. The PM should establish what has changed, why it is required, the likely cost and programme effect, and who has authority to approve the variation before uncontrolled expenditure develops.
Scenario 3 — Subcontractor Delay
A critical subcontractor is three days behind programme because they have assigned fewer technicians than originally planned. Their delay is now preventing two other work packages from starting.
Question:
What is the appropriate Project Manager response?
A. Wait until the subcontractor catches up naturally
B. Record the delay, assess the programme impact, agree a recovery action and coordinate the affected interfaces
C. Immediately terminate the subcontractor without discussion
D. Move the project completion date without informing stakeholders
Reveal answer & rationale
Correct answer: B
Why:
Subcontractor delay must be actively managed. The PM should identify the cause, quantify the effect on dependent activities, agree practical recovery measures and communicate the impact to the relevant project stakeholders.
Scenario 4 — Physical Work Complete
A subcontractor has completed a machinery-service package and requests final payment. The physical work appears complete, but the service report, test results and warranty information have not yet been provided.
Question:
Should the Project Manager close the subcontractor package?
A. Yes, because the physical work is finished
B. Yes, if the subcontractor promises to send the documents later
C. No. Confirm the agreed documentation, testing, defect close-out and handover requirements before final package closure
D. Close the package and allow the crew to obtain the records later
Reveal answer & rationale
Correct answer: C
Why:
Subcontractor completion includes more than physical work. Required test records, service reports, certificates, manuals, warranties and defect close-out form part of the project deliverable and should be controlled before final closure.
