Two quotations can show different totals because they describe different work. A reliable comparison starts with scope, assumptions, exclusions and the process for approving variations—not with the final number alone.
How should you compare two shipyard quotations?
Compare the scope of work before the total price: included tasks, quantities, materials, component brands, estimated labour hours, subcontractors, haul-outs, testing, disposal, taxes and exclusions.
Then define how extras and change orders will be handled. Additional work should not proceed without a clear description, price or pricing basis, schedule impact and traceable approval.
Compare the same scope
Ensure that each supplier received the same information. Defect description, photographs, access, requested materials and expected outcome should be consistent.
Read quantities, materials and tasks
The principal activities, materials and relevant quantities should be understandable. Very broad wording makes both cost control and completion verification more difficult.
Identify exclusions
Haul-out, handling, protection, dismantling, reassembly, disposal, tests and travel may be included or excluded. Add exclusions to the comparison before judging the total.
Assess timing and dependencies
Start date, estimated duration, material availability and links with other work affect the overall programme. In a refit, one delay can influence several contractors.
Define variation approval
Hidden conditions can emerge. Agree how variations will be documented, priced and approved before they are carried out, and identify who is authorised to approve them.
Connect payments to progress
Payment stages should reflect activities, materials and progress. Keep the approved quotation, confirmations, photographs and delivery records together.
Agree completion evidence
Clarify which checks, tests or documents will demonstrate completion. The appropriate evidence depends on the work and should be agreed with the relevant professionals.
Use a comparison matrix
Record scope, amount, materials, exclusions, timing, stated warranties, payment terms and open questions. The matrix does not make the choice, but it makes the decision transparent.
Frequently asked questions about shipyard quotations
Is the lowest quotation always the best?
No. A lower total can reflect exclusions, different materials, fewer labour hours, omitted testing or a narrower scope.
How should change orders be managed?
Each variation should be approved before execution with cost, reason and impact on schedule documented.
What evidence should be requested before payment?
Photos, progress reports, functional tests, component documentation and final labour records help connect payments to completed work.
