Design memo of 250 to 400 words: what your calculated field computes and what it told you, and what you learned about your own design from having to document it.
My calculated field computes the estimated number of occupants in each room. It takes the area of the room and divides it by the occupancy factor. I forgot to round the result to a whole number, so the schedule shows values like 3.16 people, which doesn’t make sense. As a structural engineer, I use this number to estimate how many people I can expect in each room so I can calculate the live loads. Residential rooms use a factor of 200, which means about one person for every 200 sqft. A denser room, like an assembly room, should have a lower factor. Initially, I thought it was the other way around, so I entered numbers higher than 200 for the rooms I expected to be denser. Looking at the schedule helped me realize something was off. The restaurant is very large in area but only comes out to about 24 people, which is too low for a space that should be one of the most crowded in the building. Documenting the field, seeing low numbers, and reflecting on the formula made me realize my mistake. It also shows that the schedule is only as reliable as whatever you input. The formula worked correctly, but my inputs were wrong, so the results were wrong too. In the next module, I can correct this, since it may affect the structural module. I will fix the factors for the commercial spaces, round the results, and recheck the live loads I based on them.
