Dipu Insaat | Urban Transformation, Seismic Testing and Retrofitting

Established in June 2012 by Civil Engineer MSc. Özcan Öz and Civil Engineer Mustafa Öz, Dipu İnşaat Proje ve Uygulama Ltd. Şti. is an engineering consultancy, structural design, and construction contracting firm based in Istanbul. Operating as a licensed institution authorized by the Ministry of Environment, Urbanisation and Climate Change under Law No. 6306 on the Transformation of Areas Under Disaster Risk, the company delivers engineering solutions ranging from building safety assessments to structural retrofitting and turnkey construction. Through its sister entities, including Dipu Kentsel Dönüşüm Proje Müşavirlik and the Çatalzeytin, Kastamonu office of Dipu Mimarlık Mühendislik, it manages the structural engineering process in an integrated manner.

Drawing upon more than two decades of civil engineering experience and modern technological infrastructure, Dipu Insaat evaluates the seismic resilience and integrity of residential, commercial, industrial, and public buildings in accordance with the 2018 Turkish Building Earthquake Code (TBDY 2018).

Seismic Testing and Building Performance Analysis

The company evaluates existing building stock by employing non-destructive testing (NDT) methodologies that protect structural integrity while gathering essential physical data. These assessments are critical for commercial permits, structural modifications, or statutory disaster risk evaluations:

• Non-Destructive Field Measurements: Evaluating concrete quality and using scanning equipment to detect reinforcement placement, rebar diameter, and corrosion levels within structural elements.
• Soil Investigation and Site Data: Evaluating geotechnical parameters and soil mechanics data from accredited laboratory tests to incorporate accurate ground conditions into engineering analyses.
• TBDY 2018 Performance Reporting: Modeling structures through licensed engineering software to analyze building behavior under seismic loads and generating certified performance reports for administrative and private approval.
• Official Risk Reports Under Law No. 6306: Authorizing mandatory urban renewal reports that allow property owners to access state subsidies, rental assistance, loan facilities, and municipal fee exemptions.

Structural, Architectural, and Retrofitting Design

Dipu Insaat translates structural diagnostic findings into practical architectural and engineering designs:

• Structural Engineering Design: Static and dynamic structural calculations for reinforced concrete, structural steel, masonry, and timber construction systems compliant with international and national safety codes.
• Retrofitting Projects: Formulating customized structural reinforcement designs, such as concrete jacketing, shear wall additions, and steel braces, ensuring enhanced load-bearing capacity without unnecessarily disrupting architectural functionality.
• Architectural Design and Permitting: Preparing spatial layouts and documentation, while overseeing administrative permit approvals with local authorities and municipalities.

Contracting, Building Construction, and Technical Consultancy

Beyond technical reports and digital modeling, the firm undertakes physical execution and consultancy across diverse real estate segments:

• Building Construction and Renovation: Managing structural shell contracting (rough construction) as well as comprehensive interior renovations and turnkey rebuilding projects.
• Urban Transformation Consultancy: Assisting apartment buildings, residential complexes, and urban block developments in mediating owner agreements, legal structuring, and technical compliance.
• Energy Performance Certificates (EKB): Classifying building energy efficiency and issuing compulsory energy certificates required for real estate sales and leases.
• Real Estate Valuation Support: Collaborating with licensed valuation appraisers to determine fair market property valuations for official and financial transactions.

The firm’s documented portfolio encompasses commercial centers, educational facilities, public infrastructure, and private residences, including projects such as the Directorate General of Coastal Safety (Kıyı Emniyeti Genel Müdürlüğü), Tuncel Business Center, Söyleyici Business Center, Keşan Student Dormitory, Deriş Residence, and the Tuzla Villa Project.
