FREQUENTLY ASKED QUESTIONS

Are PEB systems suitable for all kinds of weather conditions?

Yes, LOYA PEB has supplied buildings for a range of weather conditions including snow conditions, high desert temperatures, high humidity, proximity to sea, heavy rainfall, cyclone wind speeds, seismic loads, etc. Based on ambient conditions at the site and building usage, we design and manufacture the building to the specified requirements.

Do you provide a complete building package? What about flooring?

We can supply the complete steel building including standard accessories. Accessories that are not manufactured by us can be supplied as buy outs (Rolled-up doors, cranes, etc.) and can be included in our scope of supply. For mezzanine floors we will provide the steel framing and steel deck. If the flooring is of pre-cast concrete panels, we will provide the floor supports beams.

Is there any limitation on the minimum size of building?

No, we can provide anything from a small car park shed to massive industrial complexes over thousands of square meters.

How much is the saving in foundations?

The saving would be basically due to less number of column foundations due to large spans and bay spacing plus reduction in column reactions due to less dead load of steel. It is not possible to accurately quantify the cost savings as it would vary by type of project. Pre-engineered buildings utilize pierced (column) beam as a general rule, which results in lighter foundations.

How do Indian (IS) codes compare with American codes?

IS codes are of an old vintage. Design and serviceability criteria are based on older materials and do not take into account cost saving with finding high strength materials. We recommend accepting latest International design codes as these have been used literally in millions of PEB buildings in North America and other parts of the world and have a proven record of safety. Each year in the US alone, about 2 Million tons of PEBs are sold based on International codes. Also, American codes are continually updated based on the latest research findings. Hence these codes result in a safer and more economical building. IS codes are more conservative and increase weight and cost without adding value. However, if a client insists on IS codes we will design and supply in accordance with these or any other codes.

How do I obtain a quotation?

The inquiry should be sent to our sales office in your region or at sales@loyapeb.com. We will design and price each project based on the specifications provided. We will then submit a proposal offer with detailed scope of supply, price, delivery and payment terms. Proposal drawings with column reactions are provided on request.

Do you also design the foundation?

Yes, we will provide column reactions and base plate details on an Anchor Bolt plan drawing. It is our responsibility to design the foundations to support the column reactions based on local conditions.

Do you provide design calculations?

Yes, we will provide design calculations for the building, whenever requested, for approval by the consultant/client.

Are your connections on-site bolted or welded?

All field connections are bolted. There is no site welding required. This considerably reduces building erection time.

Can you provide portable units for field offices, stores and small workshops?

Since the building is assembled on-site using nuts and bolts, units can be dismantled and shifted to new locations and reassembled. We can also provide small portable units that can be transported on trucks in one piece from place to place.

It appears that you have to predetermine all requirements before ordering the building. Since this may not be possible sometimes, what is the flexibility available for any change in requirements later?

It is more economical to initially design the building incorporating future requirements like future increase in width, length, loading additional cranes, etc. This will avoid any site modification work later. However, in cases where clients require building modifications that were not previously considered, this can be done on a case-by-case basis through on-site modifications. To avoid this, consultants usually take a conservative approach and initially specify higher design loads to cover for future requirements.

How do you quote rates? What is the mode of payment?

We do not quote unit rates. LOYA PEB will design and price the building and sign the contract based on a fixed lump sum price. The standard mode of payment is 20% down payment and balance by L/C.

What sort of details are provided by you for erection assistance?

We provide detailed erection drawings, erection procedures manual, and free technical assistance through site visits by our technical representatives during erection.

Is it possible to dismantle the building and reconstruct it at another place? What will be the cost of the new and reassembled building?

Yes, it is possible to dismantle and rebuild at a new location. The costs would have to be worked out on a case-by-case basis depending on size, complexity and distance to new location.

Can we have a masonry wall as exterior skin/interior partition as in the case of residential buildings - from a bondage point of view between structural steel and masonry walls?

Yes, masonry walls can be tied to the Building Steel columns with ties for lateral support. In such cases we design the structure with low horizontal deflections to prevent cracking of masonry. Sometimes consultants will detail the masonry wall to be isolated from the steel structure which will allow for more optimization of the steel building and lower cost. When required, we can also provide beams to support masonry walls above openings etc. We will follow the requirements of the architectural drawings on any project.

Is it possible to have concrete slabs for different floors and how is the slab laid above the steel structure?

Yes, we provide steel decks over steel floor framing to cast in slabs. The steel deck acts as shuttering to support the wet concrete. The slab would be reinforced and designed for the total floor loads.

What is the alternative to rod bracing, if they are to be avoided?

We can provide angle bracing instead of rod bracing when required. At walls where rod bracing is not allowed due to access or other reasons, we will provide portal bracing as per design requirements.

How do you control temperature inside the building?

We can provide insulation at roofs and walls to achieve the required temperature value. To control the temperature inside the building beyond this requires the client to provide a suitably designed HVAC system.

Please explain compatibility of main structural frames, covering, etc. to fire resistance requirements

Fire resistance on steel structure can be achieved by enclosing the steel with a fire protection system. This can be done by spray application of fire resistance coating on steel members or enclosing the steel with gypsum board as per UL approved details. We will design the system to achieve the required fire rating.

Are modifications to the existing structure done by welding or bolting?

To field stiffen an existing structural member, it is normal practice to weld cover plates, angles, web stiffeners, etc. as per design requirements. We can provide these details if required.
