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

2. Pipeline Layout: According to the electrical and water installation drawings, workers mark the locations and lengths of the water and electrical pipelines on the walls and floors, determining the length, bend angle, and connection method for each pipeline.

3. Install embedded pipes: Construction workers install embedded pipes into walls and floors according to the plumbing and electrical drawings.

4. Installation of Electrical and Water Supply Equipment: After the piping is completed, the construction crew begins installing electrical and water supply equipment and appliances.

5. Pipe Connection: After the installation of pipes and equipment is completed, construction workers begin the pipe connection process.

6. Conduct water and electricity tests: After the installation and connection of water and electricity pipelines, construction workers perform water and electricity tests, including pipe pressure tests, water meter tests, and wire tests.

7. Tidy up plumbing and electrical lines: After testing, the construction crew will organize the plumbing and electrical lines.

8. Defect Repair: During construction, if there are issues such as plumbing or electrical pipe installation not meeting requirements or existing defects, the construction crew 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 verify if the quality and safety of the water and electricity project meet the requirements. Any discrepancies must be rectified promptly.
