Our project involves the completion of the remaining concreting works for 3 towers This project was suspended before and our company will be the one to continue it. These 3 towers are partially complete so we will just complete those not yet done. The duration is 160 days.. The client said there should only be one critical path since the duration is for all towers. But since we can work on three towers at the same time and independently, is it possible to have only one critical path?
