dividing work among several contractors
Used in construction and public works contexts where a project is split among multiple contractors rather than awarded to a single general contractor.
This public works project is scheduled to proceed by dividing the work among several contractors.
Compound of 割り (wari, 'dividing') and 普請 (fushin, 'construction'). The exact historical derivation is uncertain, but the term reflects a practice of parceling out construction tasks.
