How long will the supervision start after winning the bid?

There is no fixed time limit for this time. Before the construction of supervision bidding is in place, construction cannot be started.

In order to ensure the engineering quality, the supervision company should know the construction design scheme in advance and master the requirements of engineering construction. Therefore, we generally require the supervisor to be in place at least one month before the project starts. In practical work, bidding for construction projects can only be carried out after the completion of supervision bidding. If all goes well, the supervision company will be in place, at least three months away from the construction unit.
