How to Request a PEB Quotation: What to Include
Requesting a PEB quotation means giving the supplier enough information about building use, site, dimensions, governing code, loads, envelope, openings and special features to prepare a preliminary design and price, so that competing offers can be compared on the same technical basis.
Key facts
- Building dimensions, clear height and roof slope define the basic geometry.
- Site location and governing code determine wind, snow and seismic loads.
- Collateral loads, cranes and mezzanines strongly influence frame size.
- Cladding, insulation and accessories are a significant share of the price.
- A clear scope split avoids gaps between supply, erection and site work.
Why a complete request leads to a better quotation
A pre-engineered building is designed to fit specific requirements, so the price depends directly on the information provided. Missing details force the supplier to assume, and different suppliers will assume different things. The result is offers that look comparable but describe different buildings.
A complete request saves time for everyone. It reduces rounds of clarification, makes offers easier to compare, and lowers the risk of costly changes after the contract is signed.
Building geometry and layout
State the overall width, length and eave height, and whether width and length are measured to the steel line or to the outside of the cladding. Indicate the roof slope, the frame type you prefer if any (clear span, multi-span, single slope), and whether interior columns are acceptable and where.
Include bay spacing requirements if there are constraints such as racking layouts or door positions, and note any lean-to buildings, canopies, roof extensions, fascias or parapets. A simple sketch with dimensions is often clearer than a long description.
Site, code and design loads
Give the project address so loads can be checked, and name the governing code, for example the IBC with ASCE 7, the NBCC with CSA S16, AS/NZS 1170 with AS 4100, or the Eurocodes. If the project engineer has already set wind speed, snow load, seismic parameters or exposure category, include them.
Describe collateral loads such as ceilings, lighting, ducts, sprinklers and solar panels, and any hanging equipment. These loads are easy to forget and important for purlin and frame design.
Envelope, openings and accessories
Specify roof and wall cladding type, whether standing seam or through-fastened, insulation requirements, liner panels, color preferences and coating type. List doors, windows, louvers, skylights and ridge ventilators with sizes and locations.
Note whether gutters are external or internal, and whether downspouts are required. If you have energy or condensation targets, state them so the insulation and vapor retarder can be selected accordingly.
Special features and scope of supply
Cranes need capacity, span, class of service and hook height. Mezzanines need area, live load, floor type and stair locations. Note any requirements for future expansion, fire protection or special coatings.
Finally, define the scope split: supply only, supply and erection, foundations, anchor bolt setting, delivery terms and site conditions. A clear split prevents gaps and overlaps between the supplier and other contractors.

- Known design loads and collateral loads.
- Cladding, insulation, coatings and colors.
- Doors, windows, skylights, louvers and vents with locations.
- Cranes, mezzanines, canopies and other special features.
- Scope split and delivery terms.
- Any plans for future expansion.
Frequently Asked Questions
Do I need an engineer before requesting a PEB quotation?
Not necessarily. Many owners start with a description and sketch, and the supplier prepares a preliminary design. However, a local engineer or consultant is valuable for confirming loads, foundations and permit requirements.
Why do PEB quotations from different suppliers vary so much?
Differences often come from different assumptions about loads, code, cladding, accessories and scope. Providing the same detailed request to all suppliers makes offers easier to compare.
Should I specify the steel weight?
Weight is a result of design, not a requirement. It is better to specify performance: code, loads, deflection limits and features. Then compare offers on whether they meet those requirements.
Engineering content is general guidance. Every World Steel building is designed by qualified engineers to the code and loads of the project.
