This is the construction of projects, where responsibility for processing the project documentation is transferred to the construction contractor. Combining the functions of designer and supplier into one person brings interesting benefits, especially time savings and a guarantee of the implementer for the result.
For these projects, the long-term effect is often evaluated, so a higher initial investment with lower costs during the project life cycle may be preferred to the classic competition at the lowest price. There are also no problems with the requirements for the project documentation completion, missing items in the area reports and related additional work. The Design-Build method can be used in all cases where the investor has sufficient knowledge and technical expertise to determine the requirements for a future project.
