Identified Priority 2 Concerns
− Main Building – Loading plan.
− Main Building – Cantilever.
− Main Building – Foot bridge between the original ant
the extension.
1st Priority 2 Concern
Uncontrolled loading was observed at
Main building. Most of the area of that
flood had more than 2.00 Kpa of live
loads on it. There were no loading plans
and no method of monitoring the live
load of each floor.
2nd Priority 2 Concern
The cantilever slab of the main building is about 1.50m long. It had more than 2.00Kpa
load on it in some floors. Structural details for the cantilever portions were missing in the
documents.
3rd Priority 2 Concern
The two parts of the main building were
connected by a number of foot bridges.
Our concerns are due to the following
elements seen during our survey:
- The connection pattern between the
steel bridge and the R.C building is
unknown.
- It is not clear how much live load can
the bridges can support.
-The bridges may be venerable against
seismic loads.
Identified Priority 3 Concerns
− Boiler and generator shed – Structural steel roof.
− Main Building Overall stability.
1st Priority 3 Concern
The Boiler and Generator shed contains a structural steel roof.
Our concerns are due to the following elements seen during our survey:
- Some trusses were supported by a brick lintel.
- Steel members are not restrained and are not tie down for uplift forces due to wind
- Improvised support detail for some truss
Building Extents – Overall Stability System
Sway stability of the Main
Building could be expected
from rigid frame system
(beam and column
participation) although no
ductile detailing is provided
in structural plans.
Brick infill is unrestrained
and should not be
considered.
We require that the lateral
support system is
investigated as part of a
Engineering Assessment.
Roof Waterproofing System
at Main Building
No waterproofing membrane was visible on the roof of the building. This means that any
cracks in the surface finishes on the roof will allow water to seep into the concrete slab
beneath the finishes, and cause long-term soaking of the slab. Same goes for water
tanks at roof.
Problems Observed Summary ITEM 1: Priority 2: − Main Building – Loading plan. ITEM 2: Priority 2: − Main Building – Cantilever. ITEM 3: Priority 2: − Main Building – Foot bridge between the original and the extension. ITEM 4: Priority 3: − Boiler and generator shed – Structural steel roof. ITEM 5: Priority 3: − Main Building Overall stability system.
Item No. Observation Recommended Action Plan Recommended Timeline
1 Priority 2 - Main Building - Loading plan.
Factory engineer should develop a loading plan according to existing
site condition.
Monitor the buildings live load in each floor and maintain the loading
plan.
6-weeks
2 Priority 2 - Main Building - Cantilever.Remove all kinds of live loads from the cantilever slab and keep it open
only for walking.6-weeks
3 Priority 2 - Main Building - Cantilever.Updated the drawing of Main Building and mention the cantilever slabs
area reinforcement details.6-months
4Priority 2 - Main Building - Foot bridge between the
original and the extension.
The Factory Engineer is to carry out an assessment of the foot bridges
between the original ant the extension and also update the as built
drawing.
6-weeks
5Priority 2 - Main Building - Foot bridge between the
original and the extension.
If deemed necessary by Factory Engineer, carry out any remedial works
recommended.6-months
6 Priority 3 - Boiler and generator shed - Structural steel roof.Have a Factory Engineer provide details to reinforce and stabilise the
structural elements.6-weeks
7 Priority 3 - Boiler and generator shed - Structural steel roof. Carry out any remedial work required by the Factory Engineer 6-months
8 Priority 3 - Main Building - Overall stability system.Carry out engineering assessment on the Main Building to verify that it is
stable under lateral loading.6-weeks
9 Priority 3 - Main Building - Overall stability system. Carry out recommendations of engineering assessment. 6-months
