I want to take some photography material at a construction site. How can I get permission?

Negotiate with the leaders of the relevant departments and explain clearly the plan and purpose of shooting at the construction site. After the leaders agree, a specific time will be arranged for comrades from the publicity department to accompany them. Accompanied by them, wear a safety helmet, pay attention to the safety of people and equipment, and select a location for shooting without disturbing the normal construction. It's best to do it quickly.
