I just entered the real estate industry to do personnel recruitment, and I want to ask some questions to professionals.

1. The positions you listed are all installation engineers. The professional names generally divided in universities are: electrical engineering (or building electricity), water supply and drainage engineering (also called environmental engineering), and HVAC engineering (equipment generally belongs to this major).

2. The installation contents of a complete project mainly include:

Water: water supply and drainage

Electricity: strong and weak electricity

Heating: ventilation

Some are also equipment engineers, who are mainly responsible for elevators, generators and other equipment.

3. A complete project must cover the job responsibilities within the above-mentioned scope of work. As for what is combined or divided, it depends on the characteristics of each project. This aspect is generally considered by the employing department.
