Before the quotation
Plot and building areas, production and office needs, existing designs, material preferences and target programme are assessed together. Responsibilities for design, approvals and specialist equipment are defined.
SCOPE OF WORK
Turnkey Construction
We coordinate the entire construction process, from excavation and foundations to building services, finishes and landscaping, delivering your building ready for use within the agreed scope.
ENGINEERING AT OUR CORE
Turnkey construction means more than completing the structural shell. It means delivering a building ready for its intended use, including building services and finishes, within the agreed design and contract scope. Factories, offices and homes can be delivered on a turnkey basis using different structural systems.
We define the scope together at the outset
Design, material choices, work packages, programme and handover conditions are clarified at the start. Each party’s responsibilities and any excluded specialist equipment are documented.
Structure, services and finishes as one coordinated process
Excavation, foundations, the structural frame, roof and facade are followed by electrical and mechanical services, partitions, floor and wall finishes, painting and other finishing works. Construction is coordinated in line with approved designs and the agreed scope.
Handover ready for use
Final inspections and outstanding work are reviewed before handover. Necessary processes for the building’s use are coordinated according to each party’s responsibilities. The aim is to complete all agreed works.
Separating production equipment from construction
Factory production machinery and business-specific equipment may require procurement and installation processes separate from building construction. Their inclusion or exclusion is specified in the quotation and contract.
Turnkey scope
- Design and cost planning
- Structure, roofing and facade
- Electrical and mechanical services
- Finishes, final inspections and handover
SCOPE AND DELIVERY01 02 03
Making the scope of a factory investment clear
Our Ankara-based team approaches factory and office investments through a defined scope, from production space to external works. To make quotations comparable, we explain not only the total price but also the works to be delivered.
During construction
Foundations and structural frame, roofing and facade, building services and finishes are coordinated within a shared programme. The impact of subsequent client changes on scope, cost and programme is assessed separately.
At handover
Agreed works are checked, with outstanding items and a completion plan identified. System checks and handover documents are addressed according to contractual responsibilities. Building handover and commissioning production machinery are separate matters.

FREQUENTLY ASKED QUESTIONS
About Turnkey Construction
What does turnkey construction include?
The structural shell, roof, facade, electrical and mechanical services and finishes are coordinated within the contractual scope. Materials, responsibilities and handover conditions are explained at the quotation stage.
Is production machinery included?
Procurement and installation of production machinery and business-specific equipment are assessed separately. Included and excluded work is clearly stated in the contract.
Where can I see your turnkey projects?
Explore the areas, structural systems and work undertaken at Ahmet Tataroğlu 1 in Başkent OSB, Özkök Gıda in Saray GİMAT and Katermak in İvedik OSB. Each reference’s scope is explained on its own project page.
How should I compare turnkey factory quotations?
Compare quotations against the same design, area definition, material specifications and work schedule. Ensure that the inclusion or exclusion of roofing and facade, electrical and mechanical services, external works, specialist equipment, application responsibilities and handover conditions is documented.
Can the factory handover date be determined at the outset?
The programme is developed by assessing design preparation, site conditions, material procurement and delivery scope together. A previous project’s duration is not an automatic commitment for another investment. Client changes and phased handovers are planned separately.
Let’s define your building together.
Building type, structural system and delivery scope are three separate, complementary decisions.
