Architectural disciplines shape the earth in every period with the structures they produce using technologies specific to that period. Building design and space planning, which started with the human need for shelter, is in constant change and transformation. The priorities always differ from the expectations of people throughout history. At first, there was only the need for shelter. As culture developed aesthetics played an important role in buildings and spaces.
SIGMA takes responsibility to protect cultural heritage which is a reflection of history, civilization, and the coexistence of multiple peoples and their ways of life. SIGMA ensures the continuity of the heritage by preserving the spirit of the buildings and spaces. Although the definition of conservation and methods change over the period, the loyalty to the heritage is essential that it is deeply seated in SIGMA’s character.
Restoration and renovation projects require history and technical knowledge with meticulous work. There are several differences between restoration and renovation. Restoration is the process in which you return the building to its original condition and aims to maintain the authenticity and original form, reproducing materials, and replicating techniques when possible. Renovation is the process in which you change the functions of the building or strengthen the bear loading system or add new extensions to provide up-to-date comfortable use. We take restoration seriously as it means bequeathing a cultural heritage to the next generations. Whereas function and suitability for purpose are the key elements of the renovation.
Surveys are perfect for identifying all aspects of a building including structural integrity, cracks and splits, fissures, lamination, concrete condition, lead roofing, and lightning protection. Our surveys are carried out by skilled operatives with years of experience. We use the latest technology in surveys like 3D laser scanning, UAV (Unmanned Aerial Vehicles), and Mobile Mapping Systems.
When buildings are examined with a 3D laser scanner, data is collected in the form of a point cloud at actual size so that restoration architects review and check if they comply with the statutes. Following, Damage Assessment is done to perform Material Analysis for restoration provisions.
History of restitution is documenting the remedies done on the building in periods aside from the original one. Restitution projects with Law No. 2863 on the Protection of Cultural and Natural Heritage in restitution projects.
We collaborate with Art Historians, Archaeologists, and Historians for restitution projects to prepare Building’s History Research Report.
We prepare Material Analysis Reports in Material Laboratories of universities or KUDEB (Conservation Application and Inspection Bureau) by obtaining the necessary permits and collecting sample materials from the buildings like stone, jointing, bedding, and plastering materials.
We prepare a Restitution Report containing information about the original building quoted by people who lived in the period if they are alive, findings from the Historical Building Archive, sample material analysis, archeological evidence, original design, and authentic documents
After understanding of nature of restoration problems and their remedial measures, our experts and consultants initiate the restoration works.
We select the restoration method not to damage the building structurally. We apply different methods of masonry, mixed and wooden structures.
Renovation is the modernization of one or several floors or even an entire existing structure by keeping or strengthening its load-bearing system while preserving its authenticity. It is important to get a detailed assessment of the condition of the building to use as data. In most renovation projects, the façade should be preserved as it is. Façade retention involves supporting existing façades or party walls to preserve the overall look of the building while new internal floor structures and layouts can be constructed to meet the needs of modern occupants. Alteration is the work intended to change the function or appearance of a building. Existing buildings often undergo alterations during their life to change, modify or improve their performance or the nature of their use. We also refurbish the buildings. Refurbishment is the process of improvement by cleaning, decorating, and re-equipping the building.
