What is PEB ?

PEB stands for Pre Engineered Buildings. It can fulfill a wide range of structural and aesthetic design requirements.

This flexibility allows PEBs to fulfill a vast range of building configurations, custom designs, requirements and applications.

The technology offers several advantages over conventional concrete or steel structures, both in terms of cost and time savings.

The Process

PEBs are primarily made up of:

Built-up “I” shaped primary structural framing members (columns & rafters),
Cold-formed “Z” & “C” shaped secondary structural members (roof purlin, eave struts & wall girts),
and Roll formed profiled sheeting (roof & wall panels).

Other features include:

Mezzanine floors,
Crane runway beams,
Roof platforms,
Catwalks,
Fascias,
Parapets,
canopies,
and Roof extensions

The PEB Advantage

Large spans

Up to 60 meters without any columns in between

Faster construction

Time is money. PEB can save up to 50% construction time compared to conventional methods. A 50,000 sqft building can be made ready for occupation within 10-12 weeks.

Cost effective

Optimum utilization of materials, built-to-design steel sections, and faster construction, all lead to direct & indirect cost savings. Lower foundation cost with wider bay spacing.

Re-locatable

PEB permits future expansion & relocation

Single source responsibility

Project co-ordination, construction management, cash flow management etc. become easy, effective & predictable since you avoid dealing with several agencies. This can be a big relief for the client

Custom designs

To suit specific needs of the customer & the location

Green buildings

Steel is one of the most sustainable building materials in the world. All steel can be recovered and recycled again and again into new high quality products

PEB vs Conventional Buildings

	PEB	Conventional Buildings
Structure weight	30% lighter through optimum use of steel, Primary framing members are varying depth sections with larger depths in areas of high stress Secondary members are light gauge (light weight) roll formed 'Z' or 'C' shaped members	Primary members selected from standard sections, which can be heavier than required, Members have constant cross-sections regardless of local stresses along member length Secondary members are selected from standard hot rolled 'I' or 'C' sections, which are heavier
Design	Quick and efficient, since basic designs can be reused and built upon Specialized computer analysis and design programs optimize material required. Computerized drafting using standard details minimizes custom details. PEB engineers design & detail almost every day throughout the year resulting in faster & more efficient designs.	Each structure designed from scratch Substantial engineering & detailing required on every project. Generalized computer analysis is require extensive input/output & design alterations. Each project is a separate case, engineers need more time to develop the design & details of the unique structure.
Delivery	6 to 8 weeks on average	20 to 26 weeks on average
Foundations	Simple design, easy to construct	Extensive, heavy foundations required
Erection cost and Time	Both costs & erection time are accurately known. Erected by specialized PEB builders with extensive experience in erection of similar buildings. A stock of standard components enables on-time job completion should any shortage or on-site damage occur to materials. Erection process is easy, fast, step-by-step and with minimum equipment requirement	In most cases, erection costs and time are not estimated accurately Erection is slow and extensive since more field labour and heavy equipment are often required
Seismic Resistance	Low-weight, flexible frames offer higher resistance to seismic forces	Heavy, rigid structures do not perform well in high-risk seismic zones
Overall Price	Price per square meter may be up to 30% lower than conventional buildings	They have a higher price per square meter than PEB
Architectural Design	Outstanding architectural design can be achieved at low cost using standard architectural features and interface details.	Special architectural design and features must be developed for each project, which often require research and thus resulting in much higher costs.
Sourcing & Coordination	Building is supplied complete with cladding and all accessories including erection (if desired) from one single source.	Many sources of supply, project management time is required to coordinate suppliers and sub-contractors.
Responsibility	Single source of supply results in total responsibility by one supplier, including design liability. PEB manufacturers can be relied upon to service their buildings long after they are supplied to protect their reputation.	Multiple responsibilities can result in questions of who is responsible when components do not fit properly, insufficient material is supplied, or materials fail to perform, particularly at the supplier/contractor interface. The consultant carries total design liability.
Performance	All components are designed specifically to act together as a system, for maximum efficiency, precise fit, and peak performance in the field. Experience with similar buildings, in actual field conditions, has resulted in design improvements overtime, which allow dependable prediction of performance.	Components are custom designed for a specific application on a specific job. Design and detailing errors possible when assembling the diverse components into unique buildings. Each building design is unique, so prediction of how components will perform together is uncertain. Materials which have performed well in some climates may not do so in other environments.
