#Letterbox
-Note circulation to avoid dead end
-note recess underneath for handicap, min 230mm
-clear space between 2 back to back to be min 1200mm. as it is term as " secondary access"
#Sunken Planter
- so as not to block view, as raised planter, will have raised railing
-but note if sunken, soil has to be enough to plant .
#Lift Lobby
-Height max 3m? by TMArch? as services above head, vendor has feedback that need to have ladder to reach.
-*Telecom cable tray routing, services needs to be firmed up early, so as to avoid routing through lift lobby. If services, "services running though corridor to be in fire-rated board"
-As even if design allows for high void, if this is not taken care, lobby height has to be low, here is 2600mm.
-note size of tiles above head, more than 2.4m, no need tiles?
-Lift Motor-room if present, then last 2 floors don't need to have E&I & TMS detail.
#Self-Tapping screws vs Self drilling
-self drilling needs a pre-drilled hole
-note for self tapping, suitable depth of bit is dependent on thickness of material to drill through.
-self tapping screw
-Entirely done off-site is best: As this increases productivity, and with less people on site, less to safeguard
#Accessible Toilet
-2x2m clear so that it includes tile thickness
-note critical dimension of 750mm, rigel has a 750mm, note behind it needs a space for cistern
-note basin needs to have enough depth for leg space
-clear space outside 1.2m, if no accessible wc inside
#Lower roof (note RVO..penalty)?
-"lower roof slab ends at corridor, solution was to add a roof gutter". extend floor edge for rwdp
-key issue is how to address "roof gutter" at lower roof.
-note when u say floor edge-->parapet
-aircon ledge has a vent pipe. note location of this may overlap with location of gondolo stumps.
##Perspective##:
-If its done wrongly, so what?
-whose responsibility is it?
