A PMI was issued for some additional works.
The Contractor is now claiming retrospectively for an additional boat and boatman to undertake the works for the CE by ferrying the workman around the site. However records show that during the CE works the boat was also used (75% of the time) to ferry workers for the contract works.
The Contractor is claiming the full costs, however, should the quote be adjusted to reflect an assessment of the time that the boat has been used on CE works? I.e. 25% of the cost?
