The document discusses live load management in buildings such as ready-made garment factories. It defines different types of live loads and provides examples of typical live loads from equipment, materials, and workers. It emphasizes that live load management is important when the structural capacity is below code compliance. Exceeding the structural capacity can cause damage or failure. It also provides guidance on monitoring live loads, relocating excess loads, and record keeping to help manage live loads.

2. TYPES OF LOAD
LIVE LOADS
DEAD LOADS
FURNITURE
EQUIPMENTS &
SEWING MACHINES
FEBRIC & FINISHED
GOODS

3. LIVE LOAD MANAGEMENT
Load Management is of Paramount
Importance in Buildings Where the
Assessed Structural Capacity is below
code compliance for the Intended Use.

4. LIVE LOAD MANAGEMENT
Load exceeding the
structural capacity may lead
to structural damage and
potential failure .
Some structural elements
may not show signs of
distress(brittle failure).

5. Operational Live Load in RMG Buildings
Operational live load is
Estimated at 2kpa(200kg/m2)
Breakdown of Operational Live Load
In RMG Buildings
Description Weight Weight
Furniture 20-40 kg 10-20
Sewing Machine 10-20 kg 5-10
Fabric 10-40 kg 5-20
Workers 74-270 kg 37-135
Total 115-370 57- 185
!! No Margin for Storage,
Heavy equipment, water tanks

6. Structural Risk Rating vs Structural Capacity

7. Assessment of Superimposed Dead Loads
 The Factory assignment Load
Manager or factory appointed
Engineer must ensure the finishes
are within the capacity of
supporting structural members.
Tiling or light finishes typically 50-
75mm thick.
Internal partitions and thicker
finishes are sometimes
Provided in the toilets areas and
Other ancillary rooms.

8. Stacking of Fabric rolls
Equivalent for calculations

9. Examples
 31x 22.5 x 4 = 2790 kg 2790 x 2/(1.7+1.7+3.6) x
2=398>200kg/m2.
Stacking of fabric rolls calculation
Each compartment is 2m long.
Total weight per m2
Maximum 31 rolls are
stacked in one
compartment
Each roll Weighting
20-25kg => Average of 22.5 kg.
3 compartments are used in height
+ stacked rolls
on the top shelf = 4 compartments.
Compartments are positioned
Back to back , therefore twice the weight.
Stacked material shall
not exceed 2 shelves.

12. When load management is required?
If the structural load capacity is well below the compliant
load.(St2/St3)
Possibility of excessive load i.e. heavy machines, heavy stack
of raw fabrics on suspended floors, heavy suspended
services etc.
Storage Areas where the load is excessive and may vary
overtime.

13. How to monitor
 Factory to assign a full time live load manager and provide him with training.
 Factory Engineer to prepare live load plans and display them on floors.
 Provide load marking on all floors.
 Relocate excess loads (beyond capacity) to ground floors.
 Keep minimum required fabrics in sewing lines and remove completed items
on regular basis.
 Keep record of, Daily checked of live load , Database sheets of heavy
equipment's, Calculation of live load in critical areas(storage, water tanks etc.)
Engineer calculations/certifications that demonstrates the structural capacity.

14. Benefits of live load management
Preserving lives
Preserving assets and enhancing its longevity
Install good practice within workers
Organized and tidy layout
Comply NTPA requirement
