A spokesman for Dublin City Council is confident that maintenance work on the Spire will get under way tomorrow morning.
A 120m high crane will be used to work on the structure's lighting and to clean it from top to bottom.
Up to eight maintenance workers will use power washers and spray-on cleaning agents to polish the Spire.
The two-day project is subject to weather conditions but Central Area Manager with Dublin City Council, Charlie Lowe, says is confident it will go ahead as planned.
Traffic restrictions will apply in the vicinity of O'Connell Street during the works.
