How much is the first-class constructor (electromechanical) affiliated?

The annual fee for the first-class certificate of mechanical and electrical specialty in Beijing and Shanghai is around 35,000, and that in most other cities is around 30,000, depending on whether the certificate-using unit is in urgent need. If it is urgent, the charge can be higher, depending on your luck. This is usually paid annually instead of monthly, and paid directly after signing the agreement.

Natural endowment

For example, a large number of contractors or enterprises have mastered certain social relations resources. They either have no construction qualification at all, or only have professional subcontracting qualification or labor subcontracting qualification, or only have low-level general contracting construction qualification, so they can't participate in the project bidding that only high-level qualified construction enterprises can be shortlisted.

competence

The affiliated construction enterprises have the qualification certificates suitable for the requirements of construction projects, but they often lack the ability to undertake projects, or even if they have the construction ability, because of the black-box operation of a large number of project bidding, the probability of bidding and winning the bid by themselves is almost zero, so the construction enterprises need to "cooperate" with powerful and related affiliated enterprises.
