The Pre Engineering Building Structures are the new way of construction. It’s a new technology for a reliable and cost-effective solution. Like any other technology, PEBs have both advantages and disadvantages. Let’s see some of the
Advantages and Disadvantages mentioned below.
Cost-effective: Save up to 40% as compared to conventional methods of construction.
Flexibility: It is extremely agile and flexible to transport, install, and maintain.
Reliable: It provides high strength and reliability.
Lightweight: Being lightweight it helps to reduce the load in a structure.
Simplicity: It is fast and simple to install in any weather conditions.
Optimization: High optimization and synchronization of land resources.
Low resistance to fire: Steel starts to melt at a temperature beyond 600 degrees Celsius. It loses its strength and collapses easily. However, to deal with this problem it is covered with concrete and ceramic as a fireproofing method.
Corrosion: This is another concern. To avoid it is coated with anti-rusting paint on the outside to prevent rusting and protect it.
The list of advantages offers value more to consider than the disadvantages it has. The PEBS is very different from the conventional method of building a structure.
When building a Pre Engineered Building Structures; it is very important to consider some major factors which will determine and govern the future of the project and the overall process of constructing it. These factors are broadly categorized as technical or practical. These categories are further categorized into subcategories which are as follows:
1. Project Design
2. Components Used
3. Materials Used
4. Applied Construction Load
1. Purpose of Structure
2. Site Complexity
3. Cost of material
4. Service Provider
A good design is an important factor to consider making a building long-lasting and a meaningful investment. It impacts every aspect of the project like cost, usability, etc. The design of a PEB is based on various aspects such as dimensions, geographical location, weather conditions, available open area, and other seismic conditions. Buildings with standard designs, dimensions, and sizes save a lot of cost as compared to unconventional designs.
The customization of design is done with size and shape using various components of PEB building. Even a small change in design can have a huge impact on the project. With experience and expertise, you can get different options to solve any design challenge.
In general, a design includes components like panels and fixtures, materials for interior and exterior, paints and coatings, windows and doors, roof, wall, Vents, and Overhangs. The different components are designed to optimize material usage and reduce the structural weight of the project. Apart from the business requirements the design also needs to consider various local regulations that can impact design very much.
STAAD.Pro is one of the most reliable and easy to use.
It is extremely user-friendly and intuitive 3D model generation software. It provides a powerful analysis and multi-material design facilities and seamless integration with other modeling and design software.
Different components are used to make a PEB steel building constructions. These components make the framework of the structure. Entire
Main or Primary Frame
The rigid steel frame at the center of a building is considered as Main Frames which comprises columns and rafters. The splice plate is then welded to each end of the tapered sections in the structure. The frame structure is erected with the splice plates which are connected with other sections of the structure with the help of bolts.
Purlins, Grits, Eave Struts
These are the secondary members in a structure that is used to support roof panels and walls. Purlins used on the roof, Grits used on walls, Eave Struts used at intersections.
The secondary member is used as struts that resist the applied loads on the structure such as wind or earthquake. They impose lateral support to the mainframe member flanges of the structure which increases the frame capacity.
The insulation panels are used for covering purposes. These panels are a generally corrugated steel sheet that is used as a roof, wall sheets, wall liners, room partitions, and soft sheets. Steel sheets are produced from steel coils of high tensile stress with a thickness of 0.40 mm to 0.80 mm.
The choice of materials determines the quality and usability of any PEB project. Materials are used for both interior and exterior purposes such as insulation, decoration, etc. These materials are often affordable and eco-friendly in nature. Different materials are used in PEB structures which are Steel, Aluminum, Wood, Fiberglass, etc.
Applied Construction Load
Overload or excess load in a structure can cause stress, displacement or can cause total structural failure. To avoid this situation, a thorough structural analysis is done to understand the effects of combined load on a structure.
Apart from civil structures the structural loads also apply to various mechanical structures like heavy machineries, ships, aircraft, rockets, submarines, satellites, space stations and many more. The evaluations of these structural loads are based upon various globally accepted and pre-determined technical standards, regulations, and specifications.
There are four types of load applied viz. The dead load, Live load, Impact load, and Cyclic load.
Dead loads: A static or stationary force which is constant for a longer period of time. The force can be compression or tension.
Live load: These are dynamic, variable and moving loads in nature. It involves factors such as vibrations, impact, fluid dynamics, momentum, etc.
Impact load: The application of impact load on the material is below 1/3rd of the natural vibration of that material.
Cyclic load: a Cyclic load is a form of reoccurring loads which occur due to vibration. It can lead to fatigue and damage or failure in a structure.
Different combinations of loads are applied to a structure.
There could be a combination of different type of loads can act at the same time on the structure. The combinations of these loads are added and termed as factored loads to calculate and decide the “required strength” in a structure. The dead load and live are usually combined. In every structure it is always specified different combinations of loads calculating expected load scenarios, factors and weights to ensure the safety of the structure.
Non Technical OR Practical
The success of a construction project depends on the detailed consideration and analysis of technical factors. These factors may be both direct mad applied in nature. However; most of the projects fail not due to the technical factors but due to not considering some important practical aspects of the projects.
There are many examples where in spite of having a perfect blueprint hand with all the technical know-how, men, money, and machineries; you simply cannot build a structure. This can happen for so many practical reasons.
Let’s understand some of those practical factors affecting constructing the Pre-Engineering Building Structures in detail.
Purpose of Building
PEB Structures can be used for both residential and commercial projects and it often proves to be the best option compared to other types of construction. In a residential project, PEB is used to build Apartments, DIY Homes, Churches, and other Community Structure. For commercial use, PEB is used to build and Industrial Structure like retail showrooms, canopies, workshops, etc.
The purpose of any PEB building greatly impacts factors like required designs, material selection, cost, time and many such other factors. Hence the purpose of a PEB is an important factor.
The choice of land is an extremely important factor to consider for a PEB Structure. The building process begins choosing the right land or plot for PEB. The land is surveyed professionally and it is marked for further process of leveling. The builders need to know everything about the plot like its boundary, soil-sand composition, and terrain, climatic and geographical challenges of the plot. Soil quality and land dimensions greatly influence design, foundation, and overall structure.
In spite of good design and well-done foundation a poor quality of soil can make the steel structures sink or shift its position while building it. It is less expensive to dig out the existing dirt and replace it with good quality soil.
Cost of Material
The cost is the ultimate factor to consider when planning building any PEB project. Cost is a derived factor that is affected by design, material, labor, time, proximity, availability, land cost, builder or service provider, etc. All these costs are extremely variable in nature. E.g. price of steel and other materials, the complexity of the design, time frame, availability of human resources, etc
Price of Steel
The prices of steel always change on a daily basis due to the rapid changes in global demand and supply. This impacts the overall cost of the project. The amount of steel required depends on the size and scale of the project. The cost per square foot of steel becomes low due to its scalability. Often a large building proves to more cost-effective as compared to a smaller structure.
The cost is inversely proportional to time. Every PEB project requires a specific time to be built.
Proximity of resources
The steel building kits travel from the manufacturer to the job site. It has a greater impact on the overall price. Hence, the proximity to raw materials is very important. It’s always not possible that the manufacturer is in the surroundings of the job site reducing the higher transportation costs.
Availability of resources
The steel building firms work with a number of trusted manufacturers at a given point in time. For every project, the companies send bidding requests to all vendors and partners for the lowest possible steel building prices. However, the firms always prefer that vendor or the manufacturer who can deliver the raw material the fastest at the lowest possible bid.
Vendor or Service Provider
When planning to construct a PEB Structure, someone needs to build it. The choice of service provider is an extremely important factor of all. Hiring an experienced provider with expertise can make a whole world of difference.
A one-point solution service provider is always recommended to have. The company can design, supply material and erect the structure. There are many companies like RituTech that provide end to end specialize the solution to any PEB project.
