The mosaic was last repaired, following my request, in 2006.
I contacted the Director of City Development about the latest concerns and have been given the following and positive feedback :
I can confirm that as part of the Public Realm Improvements recently completed in South Tay Street it is planned to undertake repairs to the damaged mosaic paving in Tay Square. An artist has been commissioned to carry out the mosaic repairs and this work is scheduled to commence on Thursday 29 July. It is anticipated that the works will take one week to complete although this is weather dependant."
