What does a project buyer check before specifying your material?
Answer
They check the performance class against the specification, the test report behind it, and whether you can supply the project's quantity to its schedule. A performance claim without a test report cannot be written into a specification, so it is treated as marketing.
A specifier is writing a materials schedule and needs a product whose numbers can survive a consultant's review.
Information to make clear
Use the fields that affect this buying decision. Leave unsupported claims out.
- Product type and standard
- The standard is what the specification will reference.
- Grade or performance class
- Strength, thermal, acoustic or fire class: the value the specifier writes down.
- Dimensions and tolerances
- Determines fit with the rest of the detail.
- Test values with the test method named
- A number without its method cannot be compared with a competitor's.
- Application and exposure conditions
- Prevents specification in a condition the product cannot survive.
- Packing, unit and delivery format
- Site handling and logistics planning.
- Production capacity per month
- Project buyers need to know the schedule can be met.
Documents to prepare
State what can be published, shared on request or issued with an order.
| Document | What it supports | Suggested handling |
|---|---|---|
| Test report against the named standardMay be requested at: specification stage | The claimed performance, measured by a stated method at a stated lab | Publish |
| BIS licence or CE marking with Declaration of PerformanceMay be requested at: approval and tender | Conformity to the market's regulatory framework for construction products | Publish |
| Batch or lot test certificateMay be requested at: with delivery | That the delivered material matches the type-tested product | Issue per shipment |
| Technical datasheetMay be requested at: first evaluation | Performance values, application method and limitations in one document | Publish |
| Environmental Product DeclarationMay be requested at: green-rated and public projects | Life-cycle environmental data, increasingly requested on large projects | Publish |
| Warranty termsMay be requested at: before specification is locked | What is actually covered, for how long, and under what conditions | Publish |
| Project reference listMay be requested at: risk assessment | That the product has performed at comparable scale | Publish |
Details to ask in an enquiry
Collect only the information needed to assess the request and respond.
- Product and grade required
- Determines whether you can quote.
- Quantity and delivery schedule
- Project supply is a schedule problem before it is a price problem.
- Project location
- Freight is a large share of delivered cost in this industry.
- Specified standard
- The specification is the real customer.
- Test certificate requirement
- Some projects require third-party testing.
- Project stage
- Design, tender and execution are three different conversations.
Related questions
Should we publish test reports in full?
Publish the summary values with the test method and standard named, and make the full report available on request. Specifiers need the numbers to compare products; the full report is what their consultant asks for once you are on the shortlist.
How do we present project references without breaching confidentiality?
Project type, city, year, product supplied and quantity is usually enough to establish relevance, and rarely needs permission. Named marquee projects are stronger, but only with written approval on file.
Is a downloadable technical datasheet still worth having?
Yes, and it should be a real PDF with the values, the standard and a revision date. It gets attached to internal emails, filed against the project and read six months later, which is a reach no web page has.
