Develop electrical and water installation blueprints: Based on the designer's plans, electrical engineers draft the installation blueprints, determining the layout and installation locations of electrical and water pipelines.

2. Pipeline Layout: Construction personnel mark the locations and lengths of water and electricity pipelines on walls and floors according to the construction drawings, determining the length, bend angle, and connection method for each pipe.

3. Install Pre-embedded Pipes: Workers install pre-embedded pipes in walls and on the ground according to the plumbing and electrical drawings.

4. Installation of Water and Electrical Equipment: After the pipeline installation is completed, the construction crew begins to install water and electrical equipment and appliances.

5. Pipeline Connection: After the installation of the pipeline and equipment is completed, the construction crew begins the pipeline connection work.

6. Conduct electrical and water tests: After the installation and connection of water and electrical pipelines, the construction crew performs electrical and water tests, including water pipe pressure tests, water meter tests, and wire tests, etc.

7. Organize plumbing and electrical conduits: After testing, the construction crew will organize the plumbing and electrical conduits.

8. Defect Repair: During the construction process, if there are issues such as electrical and water pipelines not meeting the requirements or having defects, the construction personnel must promptly repair them.

9. Completion and Acceptance Inspection: After the completion of the water and electricity installation, conduct a completion and acceptance inspection to ensure the quality and safety of the water and electricity project meet the requirements. Any non-compliance issues must be addressed promptly.
