Shipbuilding Milestone, Change Order, Yard Delay & Payment Exposure Tool

Connect construction work packages, owner/yard milestones, approved variations and payment evidence. Model the likely delivery date under resource constraints, trace schedule drivers and keep contractual extensions, pending change orders and financial exposure separate.

Fast delivery and cash exposure screen: 12 inputsCompare physical progress with the contract schedule. The forecast extrapolates achieved progress only as a planning assumption, not as a binding delivery forecast.

Project controls and owner/yard reviewSet the contract basis, then edit work packages, trade capacity, changes, payment milestones, interruptions and acceptance gates below. Completed packages are treated as historical and unfinished work is scheduled from the entered status day.

Contract / class boundary: The tool does not certify construction progress, issue a payment certificate, grant an extension of time, decide concurrent delay, establish liquidated-damages entitlement or authorize delivery. The operative contract, change orders, guarantees, class/flag approvals and acceptance records govern.

Work Packages & Predecessor Register

Unique work IDs, comma-separated predecessor IDs, planned duration, physical completion, trade and crew need. Approved change-order effort is attached to its named package; time extension is entered separately.

Use	Work ID	Work package	Predecessor IDs	Baseline days	Complete %	Trade	Crews needed	Remove

Yard Trade & Crew Availability

Model shared trade capacity across parallel packages. The recovery scenarios add one crew slot per trade or improve future production, without changing the contractual delivery date.

Use	Trade code	Available crews	Work efficiency multiplier	Remove

Variation / Change Order Register

Approved changes adjust the modeled contract price and work effort. Pending proposals are tracked separately and used only in the explicit risk scenario. A signed variation does not automatically grant an extension of time.

Use	CO ID	Scope description	Attached work ID	Cost USD	Extra work days	Approval status	Remove

Progress Payment & Certificate Register

Installment percentages are applied to the revised approved contract price. A payment is "earned / verified" here only when supporting evidence is verified and its work trigger is complete. Actual paid cash is reported independently.

Use	Payment milestone	Work trigger ID	Scheduled day	Contract %	Cash paid USD	Evidence	Remove

Yard Interruptions & Access Restrictions

Verified downtime blocks the selected trade or all active trades. Pending interruptions are monitored but not treated as certain downtime.

Use	Cause / event	Starting project day	Duration days	Affected trade	Status	Remove

Class, Owner & Delivery Readiness Gates

Unverified critical approvals block a "ready" status, even if the financial model shows a favorable delivery date. These are user-supplied statuses, not real-time class verification.

Use	Evidence / gate	Category	Critical?	Status	Owner / document reference	Remove
