What is the fixture unit count for an 18 storey dormitory building with 6 bathroom groups on each floor in class 2?

To determine the fixture unit count for an 18-storey dormitory with 6 bathroom groups on each floor classified as class 2, a systematic approach is required.

First, assess the components of each bathroom group for their contribution in terms of fixture units. Typically, in plumbing design, each type of fixture (toilets, sinks, showers, etc.) is assigned a specific value known as a fixture unit, which reflects its demand on the plumbing system. The fixture unit count is calculated by multiplying the number of bathroom groups by the number of floors and then summing the fixture units for each fixture in the groups.

In this scenario, if we assume that a standard bathroom group might consist of a few essential fixtures (for instance, a toilet and a sink), we then ascertain the total number of these bathroom groups in the building. With 6 bathroom groups per floor and 18 floors, the calculation would be as follows:

Total bathroom groups = 6 groups/floor × 18 floors = 108 groups

Next, if we assume each bathroom group equates to a specific number of fixture units based on the class of building (class 2), we would multiply the number of bathroom groups by the total fixture unit value assigned per group
