i m sure that options (1) & (4) 應該唔駛FRR (re. "copy & paste" from fire code 2011)


Clause C7.3
Provided that the fire compartment area limitations in Table C1 are complied with, separation by fire barriers are not required between different occupancies for the following
uses:
(a) Use Classification 4a; or <--- offices
(b) Retail shops in Use Classification 4b.

For shopping arcade, retail shops are not required to be separated from the common arcade or mall area by fire barriers taking into account that the shops are under a common management and a common fire alarm system actuated by a sprinkler alarm or by break glass points is installed.


Clause C4.3
Where a single-storey building does not exceed 7,000m³ in volume and 7.5m in height, any steelwork construction may be unprotected, provided that the building is separated from any adjoining building or the site boundary by a clear unobstructed open space not less than 6m
in width.

Clause C15.1
A bridge may link two or more buildings and should comply with the following:-

(a) Where fire barrier is provided at each end of the bridge, the elements of construction of the bridge and such fire barriers should have the longest of the FRR of the storey(s) the bridge links. If the fire barriers are fire shutters, by-pass lobbies clearly indicated by exit signs should be provided. The external walls at the junctions of the bridge and the building(s) should comply with the requirements in Subsection C5.

(b) Where no fire barrier is provided at each end of the bridge and the bridge is unenclosed, i.e. both sides of the bridge are provided with, throughout its whole length, protective barriers or parapets not higher than 1.2m, it should be constructed of non-combustible materials and the elements of construction should have the longest of the FRR of the storey(s) it links.

(c) Where no fire barrier is provided at each end of the bridge and the bridge is not unenclosed, it will be regarded as an integral part of the fire compartment it links and should comply with the relevant requirements in this Code with regards to the building(s) it links.


it seems that no matter what situations (a), (b) & (c) are, FRR is required for linking bridge

I don't think the question is asking Elements of Construction. Coz FRR for EOC is always required.

我反而覺得(1)唔洗FRR

1. Shopping arcade同retail shop都係under classification 4b
2. Shopping arcade同retail shop可以係used for same occupancies
大家都係serve街客
比夠dv就已經足夠

今年畢業捱緊consultant,,希望各位前輩賜教下

could you please name 1 shopping arcade in hk which is “可以係used for same occupancies“ ？

我想問bs落唔落到地盤做apc or cow個啲

利申翻垃圾ive仔一個

都有，degree grad 通常做1／2年會搵到developer／client side既工可以跳槽

因為developer鐘意請有site exp既人，bs仔想入developer既可以諗諗

其實搵啲讀bs既人去做pc仲好過搵啲讀building studies / construction management 既人做pc仲好啦，bs又熟例又識畫圖

考唔到，因為contractor 極少數有chartered bs 幫你簽簿。你要預轉左入developer 先有人幫你簽。

其實，預左唔考牌既bs,係唔係去做pc仲大發圍？
