A signed contract establishes a commitment. It does not, by itself, establish that a marine worksite is ready to receive people, equipment and materials.
That distinction deserves attention before the first mobilisation invoice is approved. At an operating waterfront, the contractor's work is only one part of the environment. Vessel movements, berth use, public access, utilities and other service providers may continue around the project. If these interfaces have not been resolved, bringing resources to site can increase cost without increasing productive progress.
My position is that mobilisation should follow a documented readiness decision. The owner needs evidence that the first planned work can proceed and that the responsibilities around it are understood. A date on the programme is insufficient.
The operating site must be part of the project plan
Start with the activity that the facility must continue to support. Identify the areas that can be released for construction, the restrictions that remain and the conditions under which access may change. The operator and contractor should agree those boundaries before they become a daily negotiation.
An access arrangement needs more detail than permission to enter. It should cover the working area, delivery and storage arrangements, affected users, permissible working periods and the route for resolving conflicts. Where an interruption to an existing service is required, the relevant owner must confirm the authorised arrangement.
Technical and environmental requirements must be established by the appointed professionals and responsible authorities. IFC's guidance for ports, harbours and terminals is a useful international reference for identifying relevant environmental, health and safety considerations. It does not establish the approvals for a particular Sint Maarten site, and it is not a substitute for an assignment-specific assessment.
The management responsibility is to ensure that required decisions have owners and evidence. It should be possible to distinguish an approval received, a submission under review and an assumption that has not yet been tested.
Readiness is specific to the work being released
It is rarely helpful to call an entire project ready when only part of the scope has been resolved. Equally, one unresolved later-stage item need not prevent a genuinely independent package from proceeding.
The practical approach is to assess the proposed release of work. Are the applicable design details available? Has the required access been agreed? Are the necessary approvals in place? Can the materials be received and used as intended? Have the responsible parties accepted the work method and the operational restrictions relevant to that package?
A conditional release should say exactly what is authorised and where the boundary lies. Otherwise, a limited permission can be interpreted as approval to proceed further than the evidence supports. Conditions need a named owner, a resolution date and a clear instruction about which work must wait.
This is where a project manager adds value: turning several separate professional and operational decisions into a sequence that the delivery team can use.
Put a price on unresolved dependencies
An unanswered question has a commercial effect when it prevents a planned activity. The report should identify that effect early enough for the owner to act.
If specialist equipment is due to arrive before access is confirmed, the relevant exposure may include standby, storage, additional handling or remobilisation. If a design decision is late, it may affect both procurement and the available installation window. These are potential consequences to assess against the actual arrangements, not automatic entitlements.
Keep the contractual position separate from the management forecast. The project needs visibility of likely cost exposure even when responsibility for that cost remains under discussion. Conversely, recognising an exposure in a forecast should not imply acceptance of a claim.
GAO's schedule guidance explains the relationship between programme delay and cost. For an owner, the practical application is to require the proposed sequence and the cost forecast to tell the same story. A completion date that assumes uninterrupted access cannot credibly support a budget that ignores the cost of restricted access.
Define acceptance before resources arrive
The end of the project should influence its beginning. Agree what the operator needs to accept the completed work: the relevant inspections, test results, records, operating information and resolution of defects. Assign responsibility for assembling these deliverables during execution.
Physical completion and operational handover can occur on different dates. If the facility cannot return to its intended use until documentation or commissioning is complete, that interval belongs in the programme and financial planning.
At the mobilisation meeting, I would expect three clear conclusions: which work can start, which conditions remain outstanding and who can authorise changes. Those conclusions should be supported by the current documents, rather than left in meeting recollections.
Marine projects involve genuine uncertainty. Management cannot remove all of it. It can prevent unexamined uncertainty from being treated as readiness, and it can ensure that scarce resources arrive when the project is prepared to use them.
