koostava

Koostava is a Russian term used to describe a specific type of construction contract used in the construction industry. In essence, a koostava is a kind of construction agreement where the contractor is responsible for both design and construction of a project. This contrasts with other types of contracts where the design is carried out by a third-party designer or engineer.

The word "koostava" is derived from the Russian word "коствать," which roughly translates to "to design and construct." The koostava contract grew out of the Soviet-era practice of assigning construction projects to a single entity responsible for both design and execution. In this arrangement, the builder takes on the responsibility of designing the project from the ground up.

The koostava contract involves the contractor offering a complete solution to the project owner, including both the preliminary design and the final construction. This means that the contractor not only builds the project but also creates the plans and specifications that detail the project's requirements. Koostava contracts can be seen as an integrated form of project delivery, where the responsibility of design and construction are merged.

In modern times, the koostava contract is adapted in many countries as it simplifies the design and construction process and improves control. It is commonly used for urban development, building infrastructure and projects, such as construction of buildings.
