Just minor suggestionsهذه محاولتي:
خطة قبول تشمل كافة المواعيد والمتطلبات والمراجعات والفعاليات بغرض الإكمال الدقيق والسريع لبنود العقد
You may have noticed that this not exactly literal, that would be very difficult and you would probably need to check with the technical people (contract for what? trade? construction? manufacturing? there are technical people in all these) for the exact meaning. This is what i understood:
Acceptance plan: I have no idea what it is, so I translated it literally
Milestones: dates in which certain parts of the work contracted upon must be completed (ex. by 12th April the government licnese must be obtained).
Deliverables: what needs to be delivered in order to fulfil the contract. (ex. if it's a construction contract, all construction related drawings, BOQs, specification, schedules..etc. are deliverables)
Reveiw: once the deliverables are delivered (i.e., the drawings submitted) they should be reviewed to make sure they have no mistakes.
Activities: whatever must be done (ex. pouring concrete is an activity).
Dependencies: I have no idea, I also did not translate it because it made no sense.
