привлеченными им

[freelancer_06]

Пожалуйста, помогите перевести.
Подрядчик несет в полном объеме ответственность за качество и сроки выполнения Работ привлеченными им Субподрядчиками.
The Contractor shall be fully liable for quality and time of execution of works by Subcontractors mobilized by it.

вот это mobilized (engaged, involved) by it. не нравится вовсе
пишу by it , а не By him, так как слвоо "его" (всмысле заказчика ) переводил как its

нужна правка

IMO
.. liable for works subcontracted to third parties

[Alex16]

The Contractor shall be fully liable for the quality and timely performance of Work(s) by Subcontractors engaged by the Contractor (by IT).

[donkey_hot]

Where work is subcontracted, Contractor shall be held responsible for quality and timeliness of works subcontracted.
imo

[Medsestrichka]

I would use simply "hired"
The Contracto is fully liable for quality and timely execution of work completed by his Subcontractors .

[donkey_hot]

Мона и 'hired', но без 'simply':)

...by ITS (Contractor's) Subcontractors

[Medsestrichka]

Contract is not an object, so it can;t be ITS, has to be his/her etc
