IOM Post Office is looking to create a bigger space for the operations at its headquarters.
The organisation is planning to extend its parcel hall as part of its mail strategy to improve facilities and to handle increasing post amounts.
The proposals are subject to planning approvals and officials are on the lookout for experienced contractors who could carry out the work needed.
Interested parties are being invited to put forward expressions of interest to the government portal before the deadline at 5pm on Monday, August 12.
