The implementation time for a "turnkey" modular building project can vary significantly depending on several factors, including the size of the building, design complexity, availability of materials, weather conditions, permit procedures, and other circumstances. However, in general, a "turnkey" project can take anywhere from a few weeks to 2-4 months.

Some key stages of the "turnkey" project implementation include:

• Design and planning. This stage can take from a few days to a few weeks, depending on the complexity of the project and the time needed for design approval.

• Manufacturing of modules. The time for module production can also vary, usually from a few weeks to a few months, depending on the volume of work and material availability.

• Transportation of modules and assembly on-site. This process can take anywhere from a few days to a few weeks, depending on the distance to the site and the complexity of the installation.

• Interior finishing and completion of construction. This stage involves the actual assembly of modules and finishing the interior, which can take from a few days to a few weeks, depending on the amount of work.

In general, a "turnkey" project can take from a few weeks to several months, depending on all these factors.
