Stone cleaning and restoration work relies upon a knowledgeable and sympathetic awareness from all who are involved. Not only does the Planning Consultant have to be able to communicate with the contractor - that communication needs to be clearly understood and passed on clearly to on-site operators so that possible misinterpretations are eliminated.
It is invaluable for architects to be able to get positive input from the contractor during a site survey or at various stages during a contract. This type of contribution often based upon long-term experience can help to provide solutions to some of the inevitable problems, which appear on-site often after a contract has started.
