A comprehensive guide covering every stage of the construction contracting process, from site survey, design and permits, and the contract to structural works, finishing and turnkey handover.
What Is the Construction Contracting Process?
Construction contracting is the undertaking of a building's completion by a contractor under agreed budget, quality and schedule conditions. A well-structured contracting process reduces the client's risk and keeps progress predictable from start to finish. In the turnkey construction model in particular, where all responsibility rests with a single party, managing each phase transparently becomes essential. As Esas Yapı, based in Kadikoy, Istanbul, we run this process through a disciplined methodology on corporate and premium projects.
The Contracting Phases Step by Step
1. Site Survey and Feasibility
Every sound contract begins with an on-site examination of the plot and any existing structure. Soil conditions, zoning rules, infrastructure connections and the client's expectations are clarified at this stage. The preliminary feasibility that follows sets out the project's approximate cost and duration, so decisions rest on concrete data.
2. Design and Permits
Architectural, structural and MEP designs are developed in coordination. Design preferences, material decisions and room schedules are established here, after which the building permit is obtained from the relevant municipality. Because Esas Yapi's architectural design team and contracting team work under one roof, the transition from design to execution avoids any loss of information.
3. The Construction Contract
The rights and obligations of both parties are secured through the construction contract. A strong general contracting agreement defines not only price, but also scope, delivery time, delay penalties and guarantees.
- Detailed definition of scope and the room schedule
- Clarifying whether the budget is fixed-price or unit-price
- Work schedule, interim milestones and delay penalties
- Progress payment periods and payment terms
- Material quality standards and brand approval procedures
- Warranty, security and final acceptance conditions
4. Structural (Shell) Works
Once the permit and contract are in place, load-bearing works such as foundations, columns, beams, slabs and the roof are executed. The shell phase determines the structural safety of the building, so concrete quality, reinforcement and formwork are inspected meticulously.
5. Finishing Works
When the shell is complete, plaster, screed, mechanical and electrical installations, insulation, paint, tiling and final claddings come into play. The perceived quality of a project is largely determined during finishing works. Esas Yapi's expertise in project execution and finishing stands out especially in facade cladding and natural stone applications; reference projects such as the Istanbul Chamber of Commerce facade cladding and Zumrut Plaza reflect this attention to detail.
6. Turnkey Handover
Once all works are finished, the building is cleaned, systems are tested and the snag list is closed. After final acceptance, the structure is handed over to the client ready for use. The turnkey model relieves the client of the burden of coordinating multiple subcontractors.
Cost Management and Work Scheduling
Successful contracting means cost management without surprises. A realistic budget based on quantity take-offs and survey summaries provides foresight against fluctuations in material prices. The work schedule, in turn, shows the logical sequence of activities and resource planning; timing the transitions between shell and finishing works correctly prevents delays and cost overruns.
The Progress Payment System
Payments are made through regular progress reports based on the volume of completed work. This approach lets the client see on site the value of what they pay for, while keeping the contractor's cash flow healthy. Transparent progress payments are the foundation of trust between the parties.
Choosing a Reliable Contracting Firm in Istanbul
Selecting the right construction contracting firm in Istanbul is a decisive choice. The firm's references, the quality of completed projects, its engineering staff and its habit of transparent reporting should all be assessed. Projects we have completed at different scales, such as Alkent 2000 Villa, Beymed Eye Hospital and Avek Automotive, demonstrate Esas Yapi's contracting experience spanning residential to corporate buildings. A properly planned construction contracting process produces not just a building, but a durable, reliable investment that retains its value.
