This document discusses and compares single-storey and multi-storey factory buildings. It notes that multi-storey buildings consist of several floors, allowing for machinery and equipment to be arranged vertically. While multi-storey buildings require less land area and provide more storage space, they have higher construction costs, more difficult material handling and supervision, poorer natural lighting, and limited expansion options compared to single-storey buildings. The document outlines key advantages and disadvantages of both multi-storey and single-storey factory building designs.

FACTORY BUILDING (Part 2)

2. INTRODUCTION
 Planning and construction of Factory
building is an important task.
 Building should be designed and built to
protect the property and workers.
 Factory building provide pleasant and
comfortable working environment.

3. MULTI STOREY or VERTICAL BUILDING

4. MULTI STOREY or VERTICAL BUILDING
 Multi storey building consist of several
floors.
 It is a vertical structure.
 Machinery and equipment are arranged
in different floors.
 Greater space is available offices can
also be situated in the same building.

5. ADVANTAGES
 LOW COST OF LAND
Multi storey building requires less
land area for construction.
In cities and towns – land prices are
high – overall cost of a multi storey
building is low.

6. Cont…
 MORE STORAGE SPACE
Greater space is available for storage.
Lofts can be built for storage purpose
 LOWER AIR CONDITIONING COST
Floor space is less, hence conditioning of air
can be done at optimum cost.

7. DISADVANTAGES
HIGH COST OF CONSTRUCTION
1. A vast amount of iron and steel, cement and
other expensive materials are used for
construction.
2. Heavy capital investment and considerable
time are required for construction

8. Cont…
 WASTAGE OF FLOOR SPACE
Considerable floor space is wasted in
constructing elevators.
Provision for fire escapes.
Additional expenditure is involved in making
these provisions.

9. Cont…
 HIGH COST OF SUPERVISION
More supervisors are required for different
floors.
Effective supervision becomes difficult.
Cost of supervision is increased.

10. Cont…
 POOR NATURAL LIGHTING
Sufficient natural light is not available to the
ground and middle floor of the building.
Arrangements of artificial lighting leads to
higher cost.

11. Cont….
 RIGID LAYOUT
Machinery and equipment are arranged on
each floor according to a particular plan.
It is very difficult to make the required changes
and shift machinery from one floor to another.

12. Cont…
 DIFFICULTY IN MATERIAL HANDLING
Raw materials and work in progress have been
moved from one floor to another.
Materials have to be move to and fro.
This increase cost and time in material
handling.

13. Cont..
 DIFFICULTY IN EXPANSION
Expansion is possible if it is included in the
initial designed process.
Else it is very expensive to expand the building
since it requires very strong foundations.
Horizontal expansion is not possible because
no extra space is available.

14. COMPARISION BETWEEN SINGLE STOREY AND MULTI
STOREY BUILDING
Point of comparision Single Storey Building Multi storey Building
Cost of construction Low High
Conservation of floor
space
High Low
Material Handling Easy Difficult
Factory Layout Flexible Rigid
Natural Lighting Good Poor
Supervision Efficient Inefficient
Fire hazards High Low
Scope of expansion Considerable Limited
Land area required Less More
Storage space Greater Lesser
