Ordering sandwich panels: how to prepare a comparable quotation request

One table can hold the enquiry, provided changes have a defined place. Columns headed “required”, “offered” and “to clarify” help distinguish compliance with the specification from a proposal for a different solution.

Begin by stating whether the order concerns wall cladding, a roof covering or another arrangement specified by the design. Give the reference and date of the documentation behind the enquiry. If panel selection is incomplete, identify the request as an exploration of options. Do not present an initial idea as an approved specification merely to obtain a price sooner.

Identify the panel type, core, thickness and both facings. Separate colour from coating type and indicate which face will be internal. Available combinations depend on the particular product. “White PIR panel” leaves too many possibilities to treat two replies as quotations for an identical element.

Record thermal, fire or acoustic requirements with their design reference, rather than as isolated keywords. Request the document supporting the offered solution for the required application. If a supplier proposes a different core or fixing arrangement, treat it as an alternative requiring assessment. A similar commercial name is not sufficient confirmation of compliance.

Where an agreed panel schedule exists, list quantities as pieces of specified lengths. For an area figure, state the width used to calculate it and how the supplier prices the item. Do not combine façade area, ordered panel area and material left after cutting into one unexplained total. They answer different questions.

Show any order allowance separately and explain its purpose. It may cover planned cutting or an agreed reserve, but should not result from automatically adding the same allowance to every project. If there is no panel layout yet, label the quantity as an estimate. Checking it before confirming delivery remains an outstanding task.

Give flashings, fasteners and seals separate lines describing their scope. State which items the installer selects and which belong in the material delivery. Avoid an undefined “accessories package” without an accompanying list. The same phrase can describe substantially different contents in two quotations.

Record delivery arrangements alongside the materials without hiding them inside a unit price. Agree the address, unloading arrangements and responsibility for the necessary equipment. Clarify whether the quotation covers a single delivery or several agreed batches. Transport should not be assumed to include unloading at the eventual installation position.

Transfer replies into matching rows while retaining currency, unit and whether prices include tax. Mark a line without a price as unpriced until its status is clarified. Missing information is not a zero cost. Only after the scope has been checked can the total show a price difference rather than a difference between a full offer and a partial one.

Collect departures from the enquiry in one place. For each proposal, record what changes, who must review it and whether other items are affected. A different panel type can require the complete package to be checked again, not merely its price difference. Retain the base option so later negotiations do not erase the original requirements.

Before ordering, request one confirmation containing the agreed schedule and accepted clarifications. Identify its revision and date. Put any unresolved correspondence item on an open-issues list. Silence after a revised enquiry is sent should not be treated as confirmation that the other party has incorporated the change into the order.

Use the approved schedule when the delivery arrives, not the first indicative quotation. Compare identifiers, piece counts and documents, recording discrepancies against the relevant line item. Photographs and a clear written record help subsequent clarification. Delivery checking is a further purchasing step; it does not replace assessment of the completed cladding installation.
