Your illumination spot check result
I checked the L5 corridor (643 SF), which has four 18W LED downlights. The Revit space calculation gives an average estimated illumination of 211 lux (about 20 fc). The target for a residential corridor is 50 to 100 lux (5 to 10 fc), so the corridor is over-lit by about two times. Cutting it to two fixtures would bring it close to 105 lux. The unit living areas came out at 66 to 108 lux against a 100 to 300 lux target, so the units need task lighting more than extra ceiling fixtures.

I ran the plumbing in Mech Shaft-1, the same shaft as the Module 7 DOAS duct. The bathroom in unit 501 is located right next to the shaft, and the bathrooms are stacked in the same location from Level 2 to Level 8. Because of this, I was able to run a 4-inch PVC sanitary stack straight down from the roof to Level 1 without any offsets. I also checked Level 8 because the unit layout changes there, but the bathroom location is still the same. The 2-inch cold water and 1.5-inch hot water risers also run through the same shaft, so I could keep the plumbing penetrations in one area.
Gravity drove the plumbing layout. The 3-inch sanitary branch needs a slope of 1/4 inch per foot, which means it drops about 2 inches over an 8-foot run. This works only because the bathroom is close to the shaft. If the toilet were another 10 or 15 feet away, I would probably have a problem with the ceiling height or need to consider another stack. I modeled the sanitary pipe first and then added the 3/4-inch hot and cold water lines around it.
Revit calculated the lighting demand using 1.0 W/sf, which gave me about 8.4 kVA for Level 5. Even though the building has large windows, daylight does not reduce that calculated demand. The 20 downlights I actually placed only use about 360 W in total. When I checked the lighting levels, the corridor came out at 211 lux, which is much higher than the 50 to 100 lux target. However, the units were only around 66 to 108 lux compared to the 100 to 300 lux target. The windows should help during the day. Daylight sensors could reduce electricity use, although they would not change the panel size calculated by Revit. Revit estimates about 19.4 kVA for Level 5 on panel LP-5.
One thing is still unresolved. The corridor currently has four light fixtures, and based on the lighting results, I think two would be enough, but I have not changed the model yet. I also ran into a problem with Model Coordination. Each MEP model included the linked architectural model in its published 3D view, which caused about 2,100 false clashes between each pair of MEP models. I hid the links in those views and republished, and the MEP clashes dropped to zero.
