General information:
* Building name: HOTEL SARINA
* Location: Kamal Ataturk Avenue, Banani
* Building type: Residential Hotel
* Storey : 22
* Office space per floor: 3825 sft
* No. of lifts: 3 ( 2 circulation lifts and 1 service lift )
* Main stair : No separate main stair only one stair as fire escape
* Fire escape: One
Criticism:
* -This building has only one stair , termed as "Fire Escape".-But according to The "Rajuk Building Construction Rules, 1996",rule no. 17/1 (pg.8), "each building should have an emergency exit separated from the main lift lobby and stair lobby, within 25m (75') from any point of the building."
* If this stair is the emergency exit then this building doesn't have any main stair. its vertical circulation is solely dependent upon the two passenger lifts and one service lift.
* Again this emergency exit, though within 35' from any point of the building, is just beside the lift lobby. The emergency door opens at a place which is not separated from the lift lobby. In case of fire hazard the workability of this stair as a fire escape is seriously jeopardized due to this non separation.
* Has no fire lobby.
* The rule of emergency exit says that all ppl should reach to safety within 2.5 minutes From this the width of the stair is calculated. Standard is, a 22" stair enables 40 persons to reach safety within 2.5 minutes.
According to the standard this building, with an occupancy of around 230, requires a stair of 126". That means atleast two stairs with 5' width But it has only one stair of 3'2".
* Emergency exit should not reach the basement. But here, as there is only one stair, it reaches the basement.
Rupayan Center
General information:
* Building name: RUPAYAN CENTER
* Location: Mahakhali, Wireless gate
* Building type: Commercial ( shopping cum office)
* Storey : 22
* No. of lifts: 3
* Main stair : One
* Fire escape: One
*Crticism:
* Though this building has a separate fire exit, its workability as an emergency exit could be seriously questioned
* The fire exit shares a common lobby with the main stair and lift core. In time of emergency one has to cross the lift lobby which is, as said earlier, the most vulnerable area during a fire attack.
* It has no standard fire to resist fire attack.
* It opens at ground floor lift lobby instead of any safe access.
* The diameter of the stair is 5'2" and riser is 10".Thsi proportion is very much unusual and puts its workability under serious question.
Concord Regency
General information:
* Building name: CONCORD REGENCY
* Location: Panthapath
* Building type: Mixeduse
* No. of lifts: 3 ( 1 capsule lift, 2 passenger lifts)
* Main stair : One
* Fire escape: One
Criticism:
* This building also has the same problem of having two stairs too close. Meaning sharing a common lobby. If fire attacks at this lobby then there is no escape way from any other part.
* A highrise building should be provided with minimum two stairs in opposite direction. So that in case of emergency atleast one could be used. Having two stairs sharing the same lobby is like having one stair , none of them could be used if the lobby is under attack. Which is very much possible cause fire travels fastest through the lift core.
* Again the fire escape reaches the basement which it should not.It should ive access to a safe place.
