Frequently Asked Questions
About Pre Engineered Buildings
How much cost variation is there between PEB and conventional buildings?
Pre Engineered Buildings (PEB) are typically 20% to 30% less expensive than conventional constructions due to longer bay spacing, use of color-coated PPGL sheets instead of brick walls, and faster completion times. This leads to quicker returns on investment for owners.
Will PEB withstand all weather conditions?
Kishore PEBs are designed based on the site’s geographic location, considering wind speeds and seismic loads. We account for regional wind speeds, snow, proximity to the sea, heavy rainfall, and extreme temperatures during the design process.
What facilities should be arranged at the site by the owner?
The owner must provide water, power, and accommodation for the crew close to or within the site. Food is arranged by the erection contractors. A crane is required for erections, and while contractors can assist in finding one locally, crane charges are borne by the contractors as per the agreed terms.
What should be the ideal height of the shed?
Shed heights are determined by their application. For factories, machinery setup and processes influence the height. Designs can optimize high bays in machinery regions and low bays in utility and storage areas. Clear Eave heights and Eave heights must be distinguished when deciding shed height.
What is the typical slope of PEB roofing?
PEB roofing is usually planned at a 1:10 ratio for an optimized design. Other ratios can be considered upon request.
How do you calculate the center height (ridge height)?
The formula for calculating ridge height (RH) is: RH = (Width / (Slope x 2)) + Eave Height. For example, with a slope of 1:10, a width of 100’, and an eave height of 25’, the ridge height would be RH = (100’ / (10 x 2)) + 25’ = 5’ + 25’ = 30’.
Is a brick wall required?
Wall cladding is generally done above a brick wall, though it can be done to the bottom without brick walls. Most owners prefer a 10’ wall height for convenience in fixing windows, lintels, rolling shutters, and doors. Wall height is determined by process or stacking support requirements.
How fast can PEB be executed?
For up to 100,000 sq. ft., material production takes about 30 days from approval, with another 30 days for erection, totalling approximately 60 days.
What if local masons are not technically strong to execute civil foundations for PEB?
We provide detailed foundation drawings based on the soil bearing capacity, including dimensions, steel cross-sections, and cement grades. Our engineer visits the site before starting the marking or foundation work to clarify details to the civil contractor or mason.
Can PEB be relocated?
Yes, PEBs can be relocated easily. In cases where factories or warehouses need to be moved, the entire structure can be reused, providing value for the investment. Conventional constructions, once demolished, are considered debris and cannot be reused effectively.
Is PEB suitable for rural godowns?
Yes, PEBs are superior to conventional constructions and are acceptable by NABARD, making them eligible for subsidies.
What is the ideal clear span (without intermediate columns)?
PEB can be designed for clear spans up to 100 meters. For cost optimization, an ideal clear span is up to 80’.
What is the finishing of primary structures?
Primary structures arrive on-site with two coats of primer. Enamel paints, supplied by the customer, are applied before or after erection by the erection contractor.
Can existing conventional building foundations be used for PEB?
Conventional shed foundations have different bay spacings compared to PEB. Whether the same foundations can be used depends on the specific foundation details.
Does wall cladding affect the ambient temperature inside the shed?
Sheet-clad sheds are typically 2 to 3 degrees Celsius warmer than fully brick wall-constructed sheds. Temperature can be controlled using Turbo Ventilators or Ridge Ventilators.
What details are needed to get the best quote for PEB?
To get the best price, provide details such as the length, width, eave height, brick wall height, number of openings required, and the location of the site.
Can an existing conventional building be extended with PEB?
Yes, existing conventional buildings can be extended with PEB. On-site measurements, existing column placements, cross-section details, and foundation details are required for design calculations.
