Istanbul hosted many civilizations and cultures in BC. The first church, built during the Byzantine Empire, was opened to worship in 360 AD and then collapsed in 404 as a result of a riot. After the destruction of the first church, the second church, called Dromikos, built by the architect Ruffinos during the reign of Emperor Theodosios II, was built on the foundations of the first church. It was opened to worship in 415. Again, this structure with a basilic plan was burned in 532 during the Nika Revolution. Emperor Justinian I (527-565) wanted to build a larger church than the first two Hagia Sophia. And upon his request, Isidoros of Miletos and Anthemios of Tralles, one of the famous architects of that age, built the Hagia Sophia that survived until today. Columns, capitals, marbles and colored stones from the ancient city ruins of Anatolia were brought to Istanbul to be used in Hagia Sophia. This building, which was called Hagia Sophia during the Justinian period, has a domed and basilic plan. There is a prayer area in the middle and naves on both sides. The upper floor is reached by four ramps and there is a gallery on the upper floor. The prayer area is approximately 79.30x 69.50 meters and 100x70 meters including the narthex.
The church started to be used as a mosque after the Ottoman Empire Sultan Fatih Sultan Mehmet conquered Istanbul. Thus, during the reign of Fatih (1451-1481 AC), new arrangements were made in the church due to the change of belief. A wooden minaret, a cistern and a madrasa were built next to it. This important historical building, which was a museum after the Republic period, continues to be used as a mosque.
Hagia Sophia, which has existed for centuries, has been maintained and repaired many times. In one of these maintenance and repair works documented and projected by our company, the current state of the floor and northern interior of the building was documented and projected. Project areas were measured with a 3D scanning device and laser scanning method, structural damages were determined with GPR. In addition, the control of the prepared sketches of the surfaces is done in place, preventing the occurrence of measurement errors that may be caused by scanning.
In the digital environment working phase, correct detection of surface distortions has been achieved by overlapping photographs on orthophoto images obtained from 3D scanning and on-site controls. With these studies, the building survey, damage analysis and material analysis projects of the project areas were prepared and their reports were prepared under the consultancy of the scientific board.
In the damage analysis project prepared, the intervention methods needed for the maintenance and repair of Hagia Sophia were determined and designed by joint studies and tests with various laboratories. The intervention report was prepared under the consultancy of the scientific committee with the project design phase, in which international protection-repair principles and techniques were applied, avoiding interventions that would harm the original structure.
