Short answer: Two separate questions decide a building materials purchase: the specification question the architect asks at the design stage, and the supply and equivalent product question the project manager asks during construction. Building materials manufacturers earn AI visibility by publishing technical performance values, certifications and reference projects as text, and by providing evidence for both questions.
An architecture office in Istanbul is finishing the facade design of a 14-storey office building. The owner is targeting LEED certification. Before choosing the cladding material, the project architect asks AI:
Decision question · Architect · Specification
“Which facade cladding panels made in Turkey have an A2 fire rating, an EPD, and have been used on high-rise buildings?”
Six months later, on the same project, the project manager asks a different question under budget pressure:
Decision question · Project manager · Equivalent
“Which local facade panel manufacturers offer an equivalent to [specified product] with the same fire rating, shorter lead time and installation support?”
Neither answer includes a local manufacturer that has made this product for years and supplied dozens of high-rise projects. Its technical data sheet sits on the website as a PDF. The fire rating and EPD aren’t mentioned in the page text. Reference projects appear only in a photo gallery. The scenario is fictional, but the picture is common in the building materials sector.
Why is getting into the specification half the decision?
In building materials, the decision is made early. Once the architect writes a product into the specification at the design stage, the rest of the process largely follows that product or its “equivalent”. A manufacturer that doesn’t get specified has to compete on the equivalent question and faces price pressure.
At this stage, the architect asks by performance condition rather than product category: fire rating, thermal conductivity, acoustic performance, durability, sustainability certifications, aesthetic options. The model looks for evidence on each of these conditions.
What happens when the technical data sheet stays in a PDF?
Most building materials manufacturers already produce the technical information: data sheets, test reports, declarations of performance, EPDs. The problem is where that information lives. Values locked inside PDFs and images show up less in the model’s answers. A value written clearly in the page text matches the question’s condition directly.
“High fire resistance” answers no question. “A2-s1,d0 fire classification per EN 13501-1” does. The same applies to thermal conductivity, product dimensions, colors and finishes.
Recro classifies this as a Content GAP. It’s the building materials version of what we saw among industrial manufacturers: the information exists but can’t be read.
Architects and project managers look for different evidence
| Persona | Stage | Evidence sought | Common gap |
|---|---|---|---|
| Architect | Design, specification | Performance values, certifications, EPD, BIM objects, aesthetic options | Values only in PDFs; no BIM library |
| Project manager | Construction, supply | Lead time, stock, installation support, equivalence | No delivery or installation information on the site |
| Structural / fire consultant | Approval | Test reports, system details, code compliance | System details shared only on request |
The same manufacturer can appear in the architect’s question and disappear in the project manager’s equivalent question, or the other way around. Recro’s Persona GAP Analysis measures this split.
The equivalent question: opportunity or risk for local manufacturers?
The equivalent question is a major opportunity for local manufacturers, especially on projects where imported products are specified. The project manager looks for a local alternative because of lead time, currency risk and installation support. The evidence the model looks for is clear: the same performance values, the same certifications and comparable reference projects.
Even when a local product is technically equivalent, the model can’t make the connection unless the equivalence is stated. Content explaining which product class it corresponds to and which standards it meets with the same values produces a direct match. Care and accuracy are needed when using competitor brand names. Building the comparison around standards and performance values, rather than brands, is the safer approach.
Why are reference projects the strongest evidence?
Unlike law and consulting, references in construction are largely public. The building, location, architect and contractor can be shared. Even so, many manufacturers show references only as a photo gallery.
For the model, a strong reference includes the project name, city, building type, product used, area applied and completion year as text. The same project mentioned together with the product in architecture publications, project news and architects’ own websites provides external confirmation. Missing confirmation is an Authority GAP.
For which manufacturers is this less critical?
If all sales go through dealers and DIY stores to small contractors and the product isn’t specified, the architect’s question matters less. In that segment, dealer and installer questions lead. For every manufacturer that sells into projects, both the specification and equivalent questions connect directly to sales results.
How does Recro make this gap visible?
The Recro Insight Model simulates the building materials decision from design to construction, through the eyes of architects, project managers and consultants. Every question where the manufacturer is missing is turned into a technical content, reference or external source action.
One simulation · 4 key pillars · 90+ steps
What sets Recro apart is four pillars built from scratch for each brand. Together they form a single simulation of 90+ steps, with each pillar producing the input for the next.
- Persona builder: Decision-maker profiles that represent the brand’s real buyers, specific to its sector and sales structure.
- Question builder: The brand-specific decision questions these people ask AI along their buying journey.
- Report builder: A report that reads the answers against the brand’s goals and competitors, together with the sources behind them.
- Action recommendation builder: A prioritized list of actions that closes the sector-specific signal gaps.
Sample finding format · illustrative
- Question: Specification · Architect · “Insulation with A2 fire rating and EPD”
- Status: The manufacturer appears in none of the runs, although the product meets both conditions.
- Reason: Fire rating and EPD information exists only in the PDF data sheet.
- Class: Content GAP
- Action: Write performance values and certifications as text on product pages; publish BIM objects.
Executive summary
- Building materials decisions are made twice: in the architect’s specification question and in the project manager’s equivalent question.
- When technical values and certifications stay in PDFs, the model can’t match them to the question’s conditions. Writing values in the page text is the fastest-acting action.
- In construction, references are public. A reference written as text with project, product and area information is the strongest evidence.
Frequently asked questions
Can we keep offering data sheets as PDFs?
Yes, PDFs are needed for download. What’s missing is having the core performance values and certifications on the product page as text as well.
Do BIM objects contribute to AI visibility?
Being in BIM libraries makes it easier for architects to find the product at the design stage and creates an external signal. Mentioning the availability of BIM objects on the product page adds another matching point for architects’ questions.
Can we use a competitor’s product name in the equivalent question?
It can be used as long as the comparison is accurate and verifiable. The safer approach is to build the comparison around standards and performance values and to describe the product class.
How decisive are sustainability certifications?
On projects targeting LEED or BREEAM, EPDs and similar documents become specification requirements. Stating clearly which products they cover meets the screening condition in the architect’s question.
Does the same approach apply to projects abroad?
Yes, but the question and sources are in English. For exporting manufacturers, we cover this in what foreign buyers see when they ask AI about Turkish suppliers.
When an architect asks AI tomorrow about your product’s performance conditions, will your product be the one specified? Recro simulates specification and equivalent questions and shows the gaps before the project starts.
