With the advent of Industrialized Building System (IBS), there is one aspect of the supply chain that has remained unregulated and subject to risk of poor quality solutions creeping in to the market place that might be structurally unsound. This largely comes from the fact that the metallurgy of these connections is critical to their suitability, so the selection of the right steel is vital to ensure their performance.

Metallurgy plays a crucial role in enabling sustainability

When construction methods changed to IBS, there was a sudden influx of new technologies to assist in the connections of the precast element; but there is a natural lag before product codes can catch up and provide the same level of total robustness as traditional construction methods.

IBS approach has been widely adopted, as it reduces construction time frames compared with conventional methods.

While the scope of BS8110 did not cover all of these new connections, at least there were some minimum requirements for the mechanical splicing of reinforcing bars.

Why is CREAM Certification important?

Ever since the adoption of Eurocode 2 (EN 1992-1-1) in 2015 the requirements for these mechanical connections became lost largely due to the fact that Europe has separate National regulations for these items provided by such organisations as CARES in UK and AFCAB in France.

Thankfully, the CIDB in Malaysia realised that there was a gap and has identified CREAM* as a certification body who can provide the same service locally to provide confidence to the users, purchasers and specifiers of constructional steels and to ensure its safety and reliability, government, private and/or non-profit bodies. However, for other more advanced technologies, where no standards exist today, this type of certification is not possible as CREAM needs a standard to audit against.

For these the engineering community needs to better understand the metallurgy and ensure that the products are fit for purpose. But at least for mechanical splices, the publication of ISO 15835:2018 means that CREAM certification is now possible.

*The Construction Research Institute of Malaysia (CREAM) is a research and development (R & D) institution for the construction industry in Malaysia. Committed to ensure that R & D programs meet the needs and requirements of the national construction industry by implementing quality management systems that meet MS ISO 9001.
