Tekfen Alanar Fruit Handling Facility, Manisa

​The new fruit handling facility of Tekfen Alanar will be located in Manisa. The Doxa87 has been providing design and consultancy service for the project in close coordination with Tekfen Engineering design team. The design of the facility follows high hygiene quality and conformity to EHEDG standards. As a part of the Tekfen's sustainability commitment, LEED requirements will also be followed to achieve best possible certification level in addition to the zero-waste design approach and on-site renewable energy generation. The facility consists of large scale refrigerated storages and process halls which are the most energy-intensive part of the project. The mechanical design of the facility address the challenges in terms of energy demand. The features of the mechanical design include zero ODP and GWP ammonia refrigeration plant, high-efficiency variable-speed compressors, air-side heat recovery, rainwater harvesting, condensation water collection, hygenic ventilation, condenser heat recovery for hot propylene glycol defrost system.

Arda Serim Houses, Datça

​The small scale sustainable housing development consists of two houses located in outside of Yaka Village on Datça Peninsula. The project occupies a steep hillside site featuring view to Eagen Sea. The site is characterized by a hot and arid climate which requires unique consideration in terms of water management. Doxa87 is carefully designed a rainwater harvesting system combined with the deep-well installation. The project has also followed the local practice to utilize natural ventilation to minimize mechanical cooling. As a key to sustainable thinking, Doxa87 team applied a deliberately simple approach like to utilize forced draft fireplace for winter heating with local biomass material. For the future-proofing purpose and full-time occupancy, the design also includes provisions for solar PV installation.

TANAP Compressor Stations, Turkey

​Trans Anatolian Natural Gas Pipeline Project have many significant challenges in terms of the scale and complexity of this project, including the remote mountainous terrain, high seismicity, cold climate. As a part of detailed design, DOXA87 was responsible to coordinate compressor station HVAC system documents and specification to ensure subcontractors  produce a fully functional, clash free design for construction. We utilized innovative design solutions including BIM based based coordination tools.

Çiftçi Towers, Istanbul

Mixed used development has been designed by John McAslan, Tunca and Mixity. Arup was the prime agent, providing project management complete design and executive architecture services for this project. The project includes two residential towers, with the lower floors of one of the tower occupied as offices, retail, and underground car parking.​Utku Başyazıcı was lead MEP engineer as part of Arup design team throughout all design and tender period.

​The building is characterized with cutting edge and sustainable mechanical design solutions including low-noise multiple room EC fan coils, rey and rainwater reclamation, high efficiency screw and centrifugal chiller plant.

Akasya Acıbadem, Istanbul 

The facade wind load analysis services for the mixed-used development including high rise towers. The CFD analyses investigates how the facade system and buildings are affected by the wind at different speeds and directions. Detailed modelling was carried out to measure the facade design pressures for all critical buildings accurately.

The CFD team also carried out a detailed wind environment study to ensure that adequate wind comfort was achieved for all accessible areas within and around the development site.

Kocaeli Light Rail, Kocaeli
​
In this ambitious project, full multi-disciplinary design services including planning, civil, geotechnical, SMEP and tunnelling and fire engineering has been provided by Arup for 32 km new light rail system. When complete, the new, twin-track line will include 23 new underground stations. It will comprise bored and cut-and-cover tunnels, mined and cut-and-cover and overground stations. MEP design service includes specialist tunnel ventilation system strategy development. As a part of Arup design team, Utku Başyazıcı has been lead MEP engineer for both station mechanical design and tunnel ventilation works in collaboration with Arup tunnel ventilation experts.
