The term “Dismantling” means to carefully take apart one or more parts of a building or structure without damaging the other parts.
The term ‘Demolition’ on the other hand implies breaking up.
The work may comprise dismantling/demolishing whole or part of work including all relevant items consisting of but not limited to stone work.
The work should generally be performed in reverse order of the one in which the structure was constructed.
Necessary propping, shoring and or under pinning shall be provided to ensure the safety of the adjoining work or property before dismantling.
The contractor shall maintain/ disconnect existing services, whether temporary or permanent.
No demolition work should be carried out at night especially when the building or structure to be demolished is in an inhabited area.
Screens shall be placed where necessary to prevent injuries due to falling pieces. Water may be used to reduce dust while tearing down plaster from brick work.
Safety belts shall be used by labourers while working at higher level to prevent falling from the structure.
First-aid equipment shall be got available at all demolition works of any magnitude.
Full time supervision should be given by experienced persons fully conversant in the type of work to ensure that the structure is stable at all times.
Dead loads as much as possible may be removed provided it does not interfere with the stability of the main arch rings but it should be noted that the load-carrying capacity of many old arches relies on the filling between the spandrels.
