8.1.8. Change of order
Due to standardized design, PEB manufacturers are able to stock large amount of elements and
accessories which can be flexibly used in many types of PEB construction. Hence change of order can
be fulfilled easily at any stage of construction, explicitly as in [15]. Cost for change of order is also
lesser in this case. In case of CSB, change of order is expensive and time consuming as substitute
sections are infrequently rolled by mills, in passing [12].
8.1.9. Future expansion
Single sourcing of PEB is advantageous for future expansion whereas multiple sourcing of CSB poses
difficulty, as in [13]. Future expansion is easy and simple for PEB whereas it is most tedious and
costly for CSB.
8.1.10. Performance
All components of the PEB system are specially designed to act together as a system for highest
efficiency. PEB designs are revised regularly with respect to the actual field conditions and in
accordance with various country codes, which resulted in improved standardized designs leading to
high performance of the structure, as in [11]. CSB system components are conventionally designed
for a specific project and the performance depends on how the individual project is designed.
8.2. Advantages of PEB
The concept of Pre-Engineered Buildings is extensively used for the construction single storey
industrial steel buildings. This system has many benefits than the conventional construction concepts
that have been using. PEB systems have numerous advantages including cost effectiveness, quality
control, speed in construction, ease in expansion, achievement of large span, long durability,
exceptional architecture, standardization of materials, standardization of design, single sourcing and
co-ordination, speed in delivery, etc, in passing [3]. By understanding the preliminary design
concepts, it is easy to achieve the design of PEB system.
8.3. Applications
Pre-Engineered Building concept have wide applications including warehouses, factories, offices,
workshops, gas stations, showrooms, vehicle parking sheds, aircraft hangars, metro stations, schools,
recreational buildings, indoor stadium roofs, outdoor stadium canopies, railway platform shelters,
bridges, auditoriums, etc, explicitly as in [13]. PEB structures can also be designed as re-locatable
structures.
IX. CONCLUSION
This paper effectively conveys that PEB structures can be easily designed by simple design
procedures in accordance with country standards. In light of the study, it can be concluded that PEB
structures are more advantageous than CSB structures in terms of cost effectiveness, quality control
speed in construction and simplicity in erection. The paper also imparts simple and economical ideas
on preliminary design concepts of PEBs. The concept depicted is helpful in understanding the design
procedure of PEB concept.
