ORGANIZATION OF THE WORKSITES
The worksite of a monument is the term used for the aggregate of material and technical infrastructure that supports the work of conservation and restoration of the monument itself. Organizing a worksite is a complex operation comprising the choice of technical equipment, arrangement of the workplace and establishing the programme for the works. Where the restoration of monuments is concerned, the special character of the buildings themselves imposes limits. Respect for the historical and artistic value of the monument demands particular care in the study for the material and technical infrastructure. The area available for installing the necessary technical equipment is usually limited and frequently the approach and transportation of the machinery to the work area is difficult. Moreover, the presence of visitors while work is in process requires special adjustments. Whereas in an ordinary construction project the installations and technical means used are well known and readily available, for the restoration of monuments special systems have to be devised that will expedite the works, without damaging the monuments or interfering with them aesthetically.
Included among the technical means of the worksite are: hoisting systems for dismantling and resetting architectural members (cranes, bridge-cranes), fixtures for sculpting and working the members and fillings, copying machines (pantographs), special pointing devices, specially built equipment for matching and joining the members, systems for moving stones and transporting material and equipment, the necessary equipment for measuring and plotting, workshops and offices for the staff, special tools, etc.
In choosing the form of the worksite installations, the aim is:
Of great importance for the successful and safe performance of a work of anastelosis is the choice of a suitable hoisting system, for which the civil engineer of the project is responsible. At present the following hoisting systems are being used in the Acropolis worksites:
Particularly important in order to take full advantage of the worksite systems is the effective organizing of the works by the civil engineer of the project. The driving force for success of the whole effort lies in the consistent progression of the works, avoidance of overlapping and particularly the response of the human manpower.
