The Dublin Port Company has started construction of primary border control infrastructure in preparation for Brexit.
The port company said it is co-ordinating closely with agencies that will be tasked with carrying out inspections on UK freight once Brexit happens.
The company said it needs to press ahead with its key infrastructure projects despite the uncertainties of Brexit.
The Dublin Port Company also published figures for the first nine months of the year, which showed that cargo volumes up almost 5% to 28.4 million gross tonnes.
Within this total, imports grew by 6% and exports by 3%.
The company pointed out that 82% of the port's volumes are in Ro-Ro trailers or Lo-Lo containers.
It said that Ro-Ro volumes grew by 4.3% to 768,000 units in the first three quarters of 2018 while Lo-Lo containers grew by 5.5% to 544,000 TEU.

Meanwhile, imports of new vehicles grew by 6% to 78,000.
It also noted that trade in Bulk Solid commodities increased by 15.9% to 1.7 million tonnes on the back of increased imports of animal feeds due to the combination of a very dry summer following the very harsh winter.
On the tourism side, Dublin Port said that passenger numbers on ferries coming into Dublin were ahead by 3.3% with the growth coming from cruise passengers.
Eamonn O'Reilly, the chief executive of Dublin Port Company, said that port volumes in Dublin continue to grow at an "extraordinary rate".
He said that by the end of this year the company is looking at 36% growth in just six years.
"This rate is outstripping our long-term masterplan growth rate of 3.3% per annum and underpins the need for us to accelerate our capital investment programme to ensure that Dublin Port has sufficient capacity for future growth," Mr O'Reilly said.
"After decades of underinvestment in port infrastructure, we need to invest €1 billion in the next ten years. This year alone, we are investing €132m, guided by our Masterplan 2040," he added.
