Is the construction unit that fills in the concealed engineering acceptance record form our own unit or the general contractor? Should our company fill in subcontractors?

If your subcontracting is approved by the owner, your information should be filled in by your own company. But if your information is stamped by the general contractor, then the construction unit should fill in the general contractor, because your name should not appear without your seal. You can ask the general contractor or the supervision unit about this matter ... don't make your own decisions, so as not to make it again.
