1. Develop Electrical and Water Installation Plans: Based on the designer's scheme, the electrical and water engineer creates installation plans, determining the layout and installation locations of water and electrical piping.

2. Pipeline Layout: Based on the electrical and water installation drawings, workers mark the locations and lengths of the water and electrical pipelines on walls and floors, determining the length of each pipe, bend angles, and connection methods.

3. Install embedded pipes: Construction workers install the embedded pipes onto the walls and ground according to the electrical and water drawings.

4. Installation of Water and Electricity Equipment: After the piping is completed, the construction crew begins to install water and electricity 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, which include water pipe pressure tests, water meter tests, and electrical wire tests, etc.

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 work not meeting specifications or defects, the construction crew must promptly address and repair them.

9. Completion Inspection: Upon completion of the electrical and plumbing work, conduct a final inspection to ensure the quality and safety of the project meet requirements. Any discrepancies must be corrected promptly.
