Historic surroundings in which cultures are built that identify a process, a way of life and the development of
society as the most obvious example of the level of production and significant savings should be handled down to
future generations. In a globalized world in which cities have quickly begun to resemble each other, the
distinguishing depicting of the history of mankind that makes it special and historic buildings and environments are
now recognized as world heritage sites the conservation of which is managed by international decisions.
We cannot deny the role of notion in architectural practice which goes beyond designing and building process. In
renovation studies concerning the maintenance, repair and protection of existing buildings, notion is meaningful
when it is fed by knowledge which comes from practice, because the most important point is to preserve structures
for the future without damaging their unique features. Determining, describing and documentation of the historical
structure’s plan and façade schemes in their own ratio in an accurate way is the most important phase of the
conservation process.
The importance of the renovation phase, which can be defined as establishing the present situation of a historical
structure and transforming it to drawings, is very significant in the total process. The simplest mistake made during
this phase can cause major problems like miscalculating building ratios which cannot be fixed even if all the other
phases are performed correctly. In this point we can clearly see the importance of the measuring process which
forms the basis of renovation. The simplest mistake made while taking measurements will affect all the whole
process in a negative way and cause waste labor and money. As can be understood from the explanation, conducting
renovation work according to international standards is directly related with minimizing the error margin in
renovation. In order to achieve more accurate results it is essential to use modern methods instead of traditional
methods.
However in this point, we must not forget that to improve the quality of work in keeping with international
standards the problems faced should be solved with instant decisions, responsibility, sensitivity and knowledge
because every structure has its own unique problems. In the process the renovator chooses or combines the hardware
and methods he/she will use.
