AAC and ALC Buyer Inquiry Checklist: What to Prepare Before Requesting a Quote

When a project team requests a quotation for AAC blocks or ALC panels, the quality of the first inquiry has a direct effect on the quality of the reply. A clear inquiry helps the supplier understand the intended wall application, prepare the correct product options and explain the commercial scope without relying on assumptions. It also gives the buyer a practical basis for comparing offers from different suppliers.

This checklist is designed for contractors, distributors and project buyers who are preparing an AAC or ALC purchase discussion. It does not replace project drawings, local code requirements or the advice of the responsible designer. Instead, it identifies the information that should be organised before the quotation process starts.

1. Identify the project and wall application

Begin with the project location, building type and the function of the wall. State whether the materials are intended for external infill, internal partitions, shaft walls, parapets or another specific application. AAC blocks and ALC panels are both cellular concrete products, but the suitable system, dimensions and handling approach depend on how the wall will be used.

A short project description is usually enough for an initial discussion. Include the project stage, the expected installation period and whether the buyer is a contractor, distributor or owner representative. If drawings are available, indicate the relevant wall areas or attach the wall schedule. This gives the supplier context without requiring the buyer to disclose unnecessary commercial detail.

2. Separate AAC block and ALC panel requirements

Do not combine all lightweight wall materials into one line item. List AAC blocks and ALC panels separately, and separate different wall thicknesses or dimensions into their own lines. For each line, note the intended wall location and the approximate quantity or wall area. This makes it easier to confirm whether a proposed material matches the application.

For an early comparison of the two systems, see the AAC blocks and ALC panels guide. The main purpose at inquiry stage is not to finalise every detail immediately; it is to make the product scope visible so that questions can be resolved in a structured order.

3. Provide dimensions and performance requirements where specified

State the requested thickness, length and height where these are already defined in the drawings or specification. If the project has requirements relating to density, compressive strength, fire resistance, thermal performance, acoustic performance or another design criterion, provide the exact wording from the project documentation. Avoid replacing a specified requirement with a general description such as “high quality” or “standard grade.”

Requirements should be reviewed against the wall design and local authority process by the responsible project team. A supplier can discuss available product options, but a quotation should not be treated as engineering approval. Clear source documents reduce the risk that two quotations refer to different material bases.

4. Build quantities from a wall schedule

The most useful quantity information comes from a wall schedule or a calculation based on net wall area. Record each wall type separately, deduct major openings and identify special areas such as shafts or parapets. Where the project is still at concept stage, an estimated wall area is acceptable, provided it is marked as preliminary.

The article How to Estimate AAC Block Quantity for a Construction Project explains a practical way to organise this information. Buyers should also identify whether the request is for blocks or panels only, or whether it may include adhesive, accessories, lifting provisions, reinforcing elements or finishing-related items. Keeping these items distinct makes a later scope review much easier.

5. Explain the site and installation constraints

Material selection is affected by how the site will receive, store and install the product. Share any known constraints: limited storage space, restricted vehicle access, phased deliveries, upper-floor handling, crane access, forklift availability or a fixed programme date. For ALC panels in particular, planned lifting and installation sequencing should be discussed early with the construction team.

For blockwork, the project team should also identify whether a thin-bed adhesive system is intended and whether the first course, openings and service penetrations have been coordinated. The AAC Block Installation Planning checklist covers the site questions that should be resolved before work starts. Giving the supplier this context helps avoid an offer that looks complete but does not suit site logistics.

6. Specify the delivery destination and commercial scope

A usable quotation needs a destination. Provide the country, city or project area, destination port where relevant, and the preferred delivery term if one has already been agreed internally. If the buyer is unsure whether to request FOB, CIF, DDP or another term, say so rather than guessing. The supplier can then explain the information needed to price the relevant scope.

Include the target delivery window and whether the requirement is a single shipment or phased supply. If the project has a preferred packing method, pallet requirement, labelling format or unloading limitation, list it. Export planning is more reliable when packing, documents, shipping responsibility and site readiness are discussed before production is scheduled. The export planning guide outlines the main questions for an international shipment.

7. Ask for a comparable quotation

When contacting more than one supplier, send the same product schedule and delivery information to each one. Ask each supplier to state the material dimensions, quantity basis, packing basis, delivery term, quotation validity and exclusions. This does not guarantee that every offer will be identical, but it makes meaningful differences visible.

Price should be reviewed together with scope. A lower price may cover a different size, packing method, shipping term or set of accessories. Buyers should note unanswered questions instead of assuming that an item is included. A simple comparison sheet with one row per item is often more useful than relying on an email thread.

8. Keep the inquiry current as the project develops

Construction projects change. Update the supplier when the drawings, quantities, destination, required delivery date or purchasing authority changes. A revised inquiry should clearly identify what changed from the earlier version. This prevents outdated quantities or commercial assumptions from being carried forward into a later offer.

Before placing an order, the buyer and supplier should confirm the final material schedule, shipping scope, packing arrangement and required documents in writing. The project team should separately confirm that the selected system aligns with approved drawings, specifications and local requirements.

A practical inquiry template

For a first AAC or ALC quotation request, prepare the following:

• Project location, building type and buyer role
• Wall application for each AAC block or ALC panel item
• Requested dimensions and specified performance requirements
• Estimated quantity or net wall area, marked preliminary where necessary
• Site handling, storage and delivery constraints
• Destination, target delivery window and preferred trade term
• Any required packing, labelling or document requirements
