Before any work is about to start as part of property maintenance, especially when it comes to repair and restore of existing structures in the building, accurate measurements need to be taken. Apart from this, there is the type of masonry that was originally used in the construction that has to be considered, along with the bedding material and the constituent parts.

Preparing the specific plan will have to show the kind of work that will be developed as well as the extreme care regarding the number or even the sequence of the units (bricks or stones) that have to be rescued. These ones should be stated in the plan and they should be carefully numbered when t hey are taken out and cleaned for storing into later re-use.
