The Traverse Chemical Injection Factory marked the progress of the railway industry in Turkey. Established in the 1930s, this factory was used to treat timber that would eventually become part of railroad tracks. This facility held equipment imported from Germany, much of which still remains intact in the building. The building was part of a group of historical buildings belonging to the Turkish railway department in the seaport district of Derince. It is a relic of the railway heritage of Turkey and has been recognized as an immovable cultural asset by the Government of Turkey. The factory is also one of the very few buildings to have survived a magnitude 7.4 earthquake that had struck Izmit in 1999.
Following the new provisions introduced to the legal framework of Turkey in 2004 to aid architectural conservation and the current trend of adaptive reuse in the country. The proposal for the former industrial site envisions it as the new urban center for the suburban town of Derince. The factory is proposed to be a themed restaurant that forms an integral part of the proposed urban development in the area. The proposal includes preservation of the systems and materials of the factory to showcase the legacy of the past. The challenging aspect of the project is the perpetual risk of earthquake due to the building’s location near the North Anatolian Faultline. Any proposal for intervention needs to be analyzed thoroughly in advance in order to avoid additional damage in the future.
The paper elaborates on the operational approach from investigation of existing conditions to the proposal of interventions for the former industrial building. The process starts with preliminary assessments of the materials and damages, which were then backed by non-destructive diagnostic testing methods such as infrared thermography and ultra-sound testing. Flat-jack testing was also conducted to identify the mechanical properties of the materials. Dynamic loading was assumed using the ground movement measurements of the 1999 earthquake recorded by monitoring stations in Izmit. This complete set of data was used in the linear elastic analysis of the masonry structure to determine the most vulnerable parts and help suggest interventions to strengthen these areas. The analysis was simulated in the before and after cases to validate the chosen interventions. The possibility of using this method of triage in other similar contexts is also discussed.
- identify the diagnostic tests that are appropriate for un-reinforced masonry buildings
- understand that data from diagnostic tests can be very comprehensive and help propose accurate interventions for preservation
- demonstrate a method for seismic analysis that can help anticipate future problems in the building
- describe the approach of understanding all parameters that contribute to the deterioration of a building to help make better conservation decisions.
