Construction project management vs. general contracting
The project manager works for the owner; the general contractor builds the building. We compare the two roles, contract structures and when you need each.

Contracting and turnkey housing
Turnkey construction and contracting
On housing, mass and social housing, shopping centres and public buildings we run every trade from structure to handover under one contract and one coordination.
Illustrative imageWhat is this service?
In turnkey construction the contractor takes on the whole execution: foundations and structure, finishing works, mechanical and electrical services, infrastructure and landscaping all fall under one contract. The client does not look for a separate firm for each trade; one party is responsible for the result and the building is handed over ready for use.
DEMAFT applies this model to mass and social housing, shopping and lifestyle centres, public buildings and commercial buildings. We can take on the whole project or a single part of it, such as the structure, the finishing works or site management.
Turnkey construction and contracting
Which problems does it solve?
- 01
Interface problems between separate contractors: one crew cannot start before another finishes, and responsibility is split.
- 02
When trades are tendered one by one, the total cost and duration cannot be seen at the start.
- 03
Waiting time and rework on site when materials, crews and equipment are not planned in one place.
- 04
Disputes at handover over which firm owns which item on the snag list.
- 05
Meeting local regulations, climate and supply conditions on projects abroad.
How is it carried out?
Work starts with a survey of the site and the existing design. We then prepare an itemised quote with quantities and unit prices; the programme and payment plan are part of that quote. After the contract, the design and detail drawings, the work programme and the material and crew plan are finalised with the client.
On site, structure and finishing works run under the same coordination. Subcontractors and suppliers are tied to a single programme and progress is reported regularly. Before handover the works are inspected, snags are cleared and the building is handed over turnkey.
Which phases does it cover?
- 01
Survey and scope
The site, the existing condition and the design are reviewed; the client’s needs and budget are discussed.
- 02
Quote with quantities
The scope is defined item by item with quantities and unit prices; programme and payment plan are agreed.

Planning

- 06
Landscaping and handover
Landscaping and external works, final inspections, clearing snags and turnkey handover.

How DEMAFT runs it
DEMAFT delivered social housing projects of 5,100 and 1,016 homes in Oran, Algeria, and the 1,000-home KİPTAŞ project in Esenyurt, Istanbul; in Istanbul it also worked on the KoruFlorya Shopping and Living Centre and provided site management for the 22-storey Avcılar Municipality student guesthouse. In Yaoundé, Cameroon, it built a turnkey petrol station and the headquarters of Cameroon’s Telecommunications Regulatory Agency (ART). A total of 7,116 mass and social housing units shows that we know how to coordinate work at this scale.
Every project follows the same process: survey, quote with quantities, planning, execution and handover. Before work starts we assess the risks on site, we have materials and details approved, and we work with stage inspections and a pre-handover checklist.
