this one is factory
large " one room" spaces. understanding more about smoke purging and compartmentation now...
if there is anything that can be convincing about a layout, it is a requirement. if one wants to do good design, one needs to understand the requirement well to support ones' case. As when a client has to choose between aesthetics and money. the clear answer is money. unless statutorily required.
A current example is now, doing a layout of a giant factory space of about 25,800m2, 3 storeys, each story is 8600 sqm. the ideal is one big space, however, think of the urban and human emotion when one looks at this big black box. unreadable, lack of any warmth, however if we can break it up into smaller blocks this would give rise to many opportunities of roof terrace, interlocking shade and shadow... Spotted in the brief, is a requirement for Smoke control of natural means. However, in the 2018 scdf, 7,4 says engineered smoke control is needed when aggregate floor area >5000sqm. here if we keep it to one giant space, 8600 is obviously > 5000 sqm.. and if this NV requirement is necessary, it would make more sense to break the giant massing into min 2 parts.
*** sala! Instead of the regular chapter3 for compartment, compartment for warehouse has a separate table at 9.8A, and smoke requirements in 9.8B where allowable area is much larger!
eg storage warehouse w sprinkler & vehicular ramp is 9000m2, n w/o is 6000sqm
For previous moh feasi one, after i presented my option 2, from a money perspective, mine was more expensive as toilet stack is further away from the entrance, hence longer and more piping cost. and that was it. probably 3 hours worth of thinking and doing just put away in less than a minute of thought and comment.
the 3 sisters. compartment, if exemption is to be have, smoke and sprinkler have to be fulfilled more.
-note compartment can be exempted ( saving of roller shutter cost?) if:
1.sprinkler can be complied;
2.smoke (7.4) n specific use cases compartment(9.8.3)
