them. The debris of the roof parapet, cornice and brick masonry
wall is collected on and underneath the east facade balcony.
The corners of the roof parapet are cracked and split as much as
30cm. The exterior and interior walls of the building bear
cracks of various shapes in 0-7cm range whereas some lean as
much as 10cm from the vertical.
The timber plaster lathing on the ceilings has partially decayed
in time; the lack of repair and maintenance and the parts
collapsed because of the earthquake have increased the rate of
deterioration due to exposure to rainwater, as a result of which
the original decoration has been partially destroyed. The roof
waters have reached the intermediate floor level as well,
causing the swelling of the timber cladding and the loss of
decorated plaster on the ground storey ceilings below. The
synthetic-based paints used in the latest repair have also caused
flaking and loss of the ceiling decoration in large pieces.
decay of various timber elements as well.
The tuff blocks used for the facade claddings are pitted, flaking
and deteriorating as a result of the effects of climatic conditions
and air pollution. The use of artificial stone panels instead of
natural ones in the recent interventions and plaster repairs with
Portland cement mixtures on the faces of the less severely
damaged natural stone panels have not only destroyed the
visual esthetical uniformity of the facades but have also caused
further deterioration due to the effects of dampness and water
soluble salts.
4. SURVEY AND DOCUMENTATION
The study was initiated with a set of 1:50 scaled survey
drawings of the building, which have been prepared following
the earthquake. These drawings, would have been acceptable
for the purposes of documentation, however they were
inadequate for the restoration of a building so intricately
decorated and so severely damaged. In order to determine the
documentation of the types, levels of damage and their causes
was crucial. As a result of these considerations, various high-
tech and traditional methods of survey had to be used together
for a proper assessment of the damage. These were classified
and analysed in terms of material deterioration, structural
deformation and causes were sought. The types, characteristics,
uses and hierarchy of materials were determined, and the
original and repair materials were separately evaluated.
