There are many advantages of pre-engineered building systems, but all advantages lead to reduced construction time. Following are advantages of Pre-Engineered Building Systems:
Reduced Construction Time:
PEB (Pre-engineered building) are a predetermined inventory of raw materials that has proven over time to satisfy a wide range of structural and aesthetic requirements. The components are engineered beforehand and standardized. Use of these standard components reduces the engineering, production and erection time. Use of customized software for design & drafting increases the speed of the project.
It can reduce total construction time on a project by at least 50% of conventional construction time. This will allow faster occupancy and earlier realization of revenue.
Since PEB’s are mainly form of standard sections and connections, the design time has been significantly reduced. Specialized computer analysis and design programs optimizes material requirement. Drafting’s are also computerized which using standard details that minimizes project custom details. The low-weight flexible frames offer higher resistance to seismic forces.
Due to the systems approach, there is a significant saving in design, manufacturing and site erection cost. The structural elements are shaped to follow the stress diagram of the member, thus reducing weight, cost and load to foundations. The secondary members
and cladding nest together reducing transportation cost. The overall price per square meter may be reduced as much as 30% lower than conventional steel.
PEB are about 30% lighter than the conventional steel structures. Hence, the foundations are of simple design, easy to construct and lighter weights.
Since all the connections of the different components are standard, the erection time is faster than the conventional time.
Flexibility of Expansion:
Buildings can be easily expanded in length by adding additional bays. Also, expansion in width and height is possible by pre-designing for future expansion.
Large Clear Spans:
Buildings can be supplied to around 90M clear spans.
As buildings are being manufactured completely in the factory under controlled conditions, the quality is assured.
Buildings are being supplied with high quality paint systems for cladding and steel to suit ambient conditions at site, which results in long durability and low maintenance costs.
Energy Efficient Roof and Wall Systems:
Buildings can be supplied with polyurethane insulated panels or fiberglass blanket insulation to achieve required ‘U’ values.
Buildings can be supplied with various types of fascias, canopies, and curved eaves and designed to receive pre-cast concrete wall panels, curtain walls, block walls and other wall systems.
Single Source Responsibility:
As the complete building package is supplied by a single vendor compatibility of all the building components and accessories is assured. This is one of the major benefits of the PEB systems.
