#2 Buffer Setback and capacity

Today i started with an idea to do a flowchart and began with the ubiquitous staircase. To understand a typical capacity of a 2m wide stair with 1m width and its capacity. Refer to #1 of Sg Code for the steps. With the most recent council flats Grenfell tower: with 6 apartments per floor, 8 pax/unit, about 50 people per floor, going by just the fire escape code, capacity is sufficient. however this is w/o the highrise code in.

For factory, shop and office, per unit width of 0.5m; capacity is 60pax. For resi is 30pax. Hence for typical stair at 1m, capacity is 120m2. Roughly at 10m2/ pax; that is a floor plate of 1200m2.

Travel distance for sprinkled, was also reviewed with 1 way and 2 way. Factory and shop at 1way: 25m, 2 way: 60m, office and resi at 1way: 30m, 2 way at 75m. this is important because when considering any cluster bigger than 1 unit, what would be an efficient module to have per block so as to reduce the stairs without being a hazard

Another thing was the setbacks for landed housing. I read about detach, terrace 1 and 2 and GCB, with the land size and also min widths. This is useful for master planning and concept design for designing min modules of land parcels. And also understanding what gives an urban city a certain perspective. The view of a perspective.
