(Hello I extended this assignment)

My model includes three restrooms (Level 1 has two, level 2 has one), and each restroom is equipped with the necessary features. More importantly, I designed a greywater collection system to save water. In addition, the fire-wet protection system was designed for safety reasons. During creating the fire protection system, I met some challenges with setting the sprinkler’s elevation.

For my northwestern side restroom, I have a 5’ 4’’ wide utility room for the pipes, the partition wall is 5’’ thick. Each level’s restroom has a small utility room to store the pipes. The east side restroom only has a 2’ 6’’ wide utility room which is quite small.

Plumbing System Element

• Water closet

• Urinal

• Lavatory

• Domestic Cold and Hot Water, I only connected my cold water to the lavatory since I have a greywater collection system.
• Sanitary Pipe, connected to all water closet and urinal and only collect wastewater
• Greywater collection supply, I connect the greywater collection pipe with my lavatory so that the greywater can be collected and reused from the greywater supply (supply for water closet and urinal)
• Fire wet protection pipe, I set the center pipe in the utility room.

Plumbing System Challenges

1. The fire wet protection system. I cannot change the fire sprinkler system elevation. I searched for several solutions and turned out I still cannot solve it. The pipes network arrangement is also hard since I need to consider my HVAC duct and structure.
2. The connection between pipes is really challenging and time-consuming. Sometimes Revit cannot provide an automatic solution so we have to calibrate the layout for a long time. If the water closet distance is close, connecting them with the sanitary pipes, greywater supply pipes are extremely time-consuming.
