• Main definitions as per the decree 7964:

– The technical control:

– The technical controller: 4 categories

Apave was among the first accredited Technical Control Office in Lebanon by Decision #1139 dated 2/11/2012 as 1st category.

• Main definitions as per the decree 7964:

– The norms and standards adopted:

Libnor:

LIBNOR is a public institution attached to the Ministry of Industry. It is

the sole authority to issue, publish and amend Lebanese standards and to give the right to use the Lebanese Conformity Mark (NL Mark).

Apave is a member in 3 committees and the head of the fire safety committee. 4


• Applicable on:

– New buildings that do not have permit yet.

– Buildings under construction that need a new permit (adding new building above existing building, adjusting the occupancy…).

Cases under discussion!

Technical third Party


• The missions – مهّمات الّتدقيق الفّني: – Mission L:

Solidity of the building and the equipments that are part of the structure, including the closing walls and coverage “clos et couverts” (curtain walls, cladding, waterproofing…).

Shoring and excavation works are not part of the mission.

– Mission PS: Seismic stability.

7


Seismic

Changing the seismic acceleration coefficient to 0,25G

0.25 g Horizontal Acceleration – Moderate seismic Risk

Adopted Norms and Standards

9

• French Norms (PS92, BAEL, DTU...).

• American Norms (UBC or IBC, ACI..).

Adaptation to French Referenced Documents (according to Libnor - NL 135)

10

• Apply the Seismic Design Rules PS92 & Guide AFPS 1992 considering a minimum value of the peak ground acceleration (accélération nominale) equal to aN = 2.5m/s2 corresponding to seismic zone II (zone de sismicité II) and to an occupancy category of normal hazard (catégorie d’ouvrages dits à risque normal). The above mentioned value is subject to an increase based on the class of hazard of the structure.

Adaptation to American Referenced Documents (according to Libnor - NL 135)

Wind

• For the calculation of the wind loads on Buildings, Structures (excluding bridges) and every portion thereof, the value of the Basic Wind Speed (or Reference Wind Speed) shall be taken from the relevant Lebanese Meteorological Authority in form of “National Wind Map”

16

Basic Wind speed (Libnor – NL 137 – draft version)

• This value shall be as per the definition of the “Basic Wind Speed” for every Referenced Documents (American UBC, IBC or French NV65).

• It is recommended that the minimum Basic Wind Speed value not be less than the value here below ( for Beirut area):

17

Basic Wind speed (Libnor – NL 137 – draft version)

• Uniform Building Code “UBC97” : Vfm = 38 m/s .

• Design under the International Building Code “IBC 2009”: V3s = 45 m/s .

• Design under the French Document “Règles NV65: 2009”: Vnormal = 35 m/s

• European Standard - Eurocode 1: Vb,0 = 26 m/s

18

• The missions:

– Mission S:

Fire safety of the project including fire resistance of the structure, architectural arrangements and electromechanical systems.

This mission also includes protection against falling : guardrails, facades, windows…

This mission does not include safety during construction.
