Прошу помочь с переводом слова build-up

The Build Up group takes over different parts of the building on different dates. It is therefore necessary that a programme is prepared for each building zone and carefully monitored, and the construction activities in the different zones well coordinated.

The Build Up group dates and the store opening date are difficult to influence once the construction process has commenced.

The retailer normally requires 8-10 weeks for the build up.

еще встречается в таком предложении:

All health and safety requirements and measures are also applicable for
visitors and all staff when the early build up works overlap the
construction phase.

Заранее спасибо
