A library in motion.

A material library looks static. Shelves of samples, each in its place, each with its data. But the reality behind it moves. Manufacturers revise ranges, fire classes are re-certified, products are replaced or discontinued. Working with outdated data risks specifications that fail at tender stage.

What changes.

Three data types change particularly frequently.

Availability. Materials go out of the range, new ones are added. For natural materials, sources change as quarries are exhausted or new ones are opened. For industrial materials, collections are revised every few years.

Certificates. Fire protection classes are time-limited. Five to ten years is common. When the certificate expires, the material must be re-tested, often with slightly different results. A B-s1, d0 classification can become B-s2, d0 after re-certification. That is not a deterioration of the material, but a consequence of today's more rigorous test methods.

Prices. Prices are not the most important thing, but they change. For natural materials they are driven by raw material costs, for industrial materials by production costs. A specification based on a price from two years ago can lead to surprises at tender.

How to keep a library current.

There are three approaches.

The first is passive. The library stays as it is, and the practice checks individually at each specification. For every question about a fire class, every question about availability, every price enquiry. This is labour-intensive and prone to error.

The second is semi-active. The practice maintains its library itself, regularly asking suppliers for updates. Quality depends on how systematically the maintenance is carried out. In practice the effort tends to drop off as other tasks take priority.

The third is systematic. Maintenance is part of a service. A provider, in our case Material Concierge, keeps the data current, checks it for plausibility, updates certificates. The information comes from the suppliers and is bundled in one place.

Why it matters in practice.

Working with outdated fire classes in a tender means specifying, having it checked, correcting it, re-specifying. That costs days. In unfavourable cases, weeks.

A current library shortens this cycle to minutes. The specification is in place, the data is correct, the project moves forward.

That is the difference between a library that is organised and one that actively works with you.
