Abstract - Construction activities around the world are growing at an incredible rate and costs are also rising day by day. Predefined buildings are an excellent solution to all the complicated problems associated with them Conventional steel and other types of buildings. Currently global building or predesigned PEB system, it is becoming a prominent segment in the construction sector. The pre-engineering building is less expensive than Conventional construction and can be designed according to specific requirements. Project development and construction Pre-engineering construction is cheap and takes less time. Default buildings can be disassembled and transported to another place to reassemble, if necessary. Premaintenance costs Technical buildings are low compared to the usual construction method. These buildings have a long life. the expectations and impact of steel on the environment are much lower than the use of a non-renewable resource and maintain the Minimum environmental impact. Like most of the materials used in the construction of pre-designed buildings are recyclable; conserves energy and has minimal impact on ecology and the environment. So pre-designed building It is the only remedy for the construction industry in creating an industrial, commercial, recreational or another type build unit within the deadline with limited use of material, energy, labor and without much damage to ecology and the environment.

Therefore, pre-designed buildings are the main contributors to the Sustainable development of the nation.

Key Words: PEB, Modern Technology, Conventional Construction 1. INTRODUCTION

India is a developed country which is the construction of mass housing taking place in various parts of the country.

From 30% of the Indian population, He lives in the city, so construction is more in urban places. The housing requirement is enormous, but there will always be a shortage of availability of the house since the current masonry construction technology cannot satisfy the growing demand every year. Therefore, an alternative must be thought of construction system as pre-designed steel buildings. India has an installed steel capacity from 35 to 40 million tons and the apparent consumption of steel is about 27-30 million tons. There is an excess capacity of flat steel Products available in India cold and hot-rolled sheets. There are Steel components that can be used in the construction of pre-designed buildings components.

The PEB concept originated in the United States. Until 1990, the use of the previous engineering buildings was mainly limited to North and Middle America. Since then, the use of pre-designed buildings has spread everywhere.

Asia and Africa, where the concept of construction in PEB has been widely spread Accepted and praised. This leads to steel savings and PEB development concepts. A growing number of major international contractor’s e Designers now enjoy significant cost and benefit savings just as quickly construction cycle deriving from this concept. The idea was that the section should be provided according to the momentum bending diagram (BMD).

In the pre-designed construction concept, the complete design is carried out in the factory and the building components are brought to the site in demolition conditions.

These components are fixed/articulated on the site and raised with the help of cranes. The pre-designed building requires a very fast construction of buildings with a good aesthetic appearance and quality construction. Predefined buildings can be widely used for the construction of industrial and residential buildings. PEB construction is 30 to 40% faster than traditional steel construction. Predefined buildings are the most appropriate alternatives to old conventional construction structures. These pre-designed configurations are not only inexpensive but also save valuable time that would otherwise have been spent pending completion of the building construction. Buildings can be multi-story (4-6 floors). These buildings are suitable for various environmental risks. PEB buildings offer a good insulating effect and would be very suitable for a tropical country like India.

A recent survey by the Metal Building Manufacturers Associations (MBMA) shows that around 60% of low-rise non-residential buildings in the United States are predesigned buildings. Pre-designed steel buildings provide the designer with innovative designs and implement them successfully since they can be built in places with limited space because they use the assembly process for construction. As for the design of the structure and the aesthetic aspect, India is far behind. Indian producers are trying to catch up; comparatively, PEB is a new concept in India. In addition, India is very good at production and other areas of the PEB. Compared to other countries, Indian codes for building design are strict but safer. IS standards are continuously updated.

1.1 PEB (Pre-Engineered Buildings) The scientific term that sounds pre-designed buildings emerged in the 1960s. The buildings were "pre-designed" because, like their ancestors, they relied on standard engineering projects for a limited number of standard configurations. Numerous factors have made this period significant for the history of metal construction. First, the improvement in technology has constantly expanded the maximum free space capacities of metal buildings. The first rigid frame buildings introduced in the late 1940s could only cover 40 feet. In a few years, 50, 60 and 70-foot buildings were made possible. In the late 1950s, rigid frames were made with 100-foot sections, corrugated metal panels available, allowing buildings to appear different from the old and tired corrugated appearance. Third, Strand-Steel Corp. introduced collar panels in the early 1960s, which allowed for a certain individuality in the design. At about the same time, cold-formed, cold-formed Z belts (also from Strand-Steel) was invented, the first factory insulated panels were developed by Butler and the first UL approved metal roof appeared on the market. But not least, the first metal buildings designed for computers also made their debut in the early 1960s. With the appearance of computerization, the plan chances became almost limitless. All these factors were combined to produce a new boom in the metal construction in the late 1950s and early 1960s. If the buyer can be limited to standard projects, buildings could be defined correctly predesigned. Once the industry started offering metal buildings custom designed to meet each customer's specific needs, the name of the pre-designed building became somewhat inappropriate. Furthermore, this term was uncomfortably close and easily confused with unsophisticated prefabricated buildings, which the new industry did not want to associate with. Even though the term preset buildings is still widely used and can also be found in this book, the industry now prefers to call its products metal construction systems.

Conventional steel buildings (CSB) are low-rise steel structures with truss roofing systems with roof covers.

Various types of roof trusses can be used for these structures depending on the tone of the truss. For large shades, a Fink type truss can be used; For the medium passage, it is possible to use a Puss truss and for small steps, it is possible to use a Howe truss. A skylight can be provided for daytime lighting and for greater daytime lighting, it is possible to use a quadrangular truss. The selection criteria for roof reinforcement also include roof inclination, production and transport methods, aesthetics, weather conditions, etc. It is also possible to select different types of economic reinforcement for composite and combined roofs, depending on the utility. Standard hot-rolled sections are generally used for reinforcing elements together with reinforcing plates.

The CSB framework of the structure considered in the study is as shown in Figure.

problem is more evident. Therefore, engineers must continually seek cost-effective solutions to reduce these costs.

3. PRO’S & CON’S of PEB (Pre-Engineered Buildings) 3.1 PRO’S: Technical competence is a critical basis and a necessity to survive in industrial competition. For the most part, companies that cannot invest in their internal research and development section are making an alliance with companies renowned for offering superior quality products. Therefore, instead of investing in their own research and development, this amount is used to purchase products and reward companies with the profits associated with the members. PEB construction is not recommended for skyscrapers, as it is not the ideal option for industrial buildings to withstand dead loads and very high loads. Therefore, the engineering experience offers low industrial buildings and their aesthetic needs with a large expansion capacity and other operational uses to put the company in better competition to manage the competition.

Currently, welded constructions are used more frequently, as they provide stiffer and stronger structures with a lower construction weight. The increase in the elastic limit of steel requires new innovative welding methods, since highstrength steels present greater welding difficulties without adversely affecting the ductility and performance of the structural system. Recently, the use of fully automatic and semi-automatic submerged arc welding leads to an increase in welding speed, as well as good quality. The elimination of smoke, smoke or any visible arch column offers ease of use and efficiency; Better quality and therefore encourages its application in the welding sector.

There are a repetitive production and supply process.

Therefore, the production arm and the supply arm should create a harmonious relationship. This raises the need for supply chain management which will help strengthen alliances with subcontractors and raw material suppliers, which would lead to a reduction in logistical costs for the company. This will bring the general economy to the project.

Steel production can be performed with expensive machines and with low-cost machines. This allows for open competition and not a barrier as a condition for newcomers.

Therefore, no company has a clear brand advantage like competition in the price ranges of Rs.75-95 / kg. Therefore, the main deciding factor is the shipping costs charged by the companies. Therefore, it is one of the main decisive concerns.

3.2 CON’S: Instability and stability are also the main concern in PEB. For this reason, the maximum gutter height is generally limited from 25 m to 30 m and stability is also fundamental due to the large distance.

Steel has a great tendency to corrode when exposed to the environment, resulting in deterioration, higher maintenance costs, and higher reconstruction costs. Although galvanization, paint, and coatings can provide corrosion protection, the overall manufacturing costs of the steel structure increase considerably. In hot and humid regions and in heavily industrially contaminated environments, the
