Examining the 2021 construction materials shortage
The session opened with Peter Caplehorn, Chief Executive, Construction Products Association (CPA). Caplehorn is also co-chair of the Construction Leadership Council’s (CLC) Brexit Movement of Building Products and Materials Group, which was started in mid-2020 over concerns about issues related specifically to Brexit.
Since that time, other issues have arisen. Noting that many of the issues are global, he predicted the trend would continue for some time.
Caplehorn said, “it’s perfectly fair to describe it as a perfect storm,” due to several situations affecting the availability of products.
In an examination of the 2020/2021 COVID-19 pandemic’s effect on different countries, Caplehorn noted that the Chinese and US economies appear to be recovering earlier than other countries. As a result, they are “sucking up large amounts of global commodities,” he said.
This action is having an impact on the availability of several products, including steel, aluminium and timber as well as the components related to these materials. He also noted that the timber shortage - which started before the pandemic - was made even worse by production issues caused by earlier warm weather in Scandinavia.
The placement of shipping containers around the world has also had an impact on materials. At the end of 2020, there were a large number of empty containers in Europe and the US; correcting that balance has taken several months. This pushed up the cost of containers significantly.
This issue was exacerbated by the ship that blocked the Suez Canal, which had a ripple effect on deliveries throughout the world. Rebalancing the location of those containers has required additional measures.
 Continuation of construction
In manufacturing, the pandemic has had an impact on shift patterns, which has added to production challenges. Caplehorn acknowledged that measures have been effective, but “...supply chains that normally run smoothly through the UK have been patchy.”
At the beginning of 2021 there were some issues with border crossings. This has been resolved for the most part, except in Northern Ireland (which continues to be an unresolved problem). However, SMEs may continue to struggle with the administrative changes brought on by Brexit.
There has also been an issue with drivers, and the haulage industry is feeling challenged by changes to the way businesses operate. As a result, drivers are being enticed away from construction and over to the supermarket sector, which has experienced increased customer demand for at home deliveries.
 CA mark transition
Another Brexit related materials availability issue is the rollout of the CA mark. The transition from CE to CA is meant to be complete by the end of 2021, but what has been uncovered in the process is that “...the UK does not have all of the testing and certification and capability and capacity that it actually needs,” Caplehorn explained.
If the UK intends to meet the 1 January 2022 deadline, “...there will be no testing and certification for certain products,” he added. Unless certain strategic measures are put in place, he predicts additional product delivery disruptions.
To clarify, he stated, “...products can’t be placed on the market because they’ve not got a CA mark. And because we transition over to a CA mark only, it means that products from Europe that are CE marked will also not be allowed onto the market.”
European manufacturers have not rushed to address the issue and are expecting the UK to provide the relevant certificates. In certain product areas, the capacity to deliver the information doesn’t exist at all, he admitted.
According to Caplehorn, some of the types of products that could include radiators, types of ironmongery, sealants and adhesives, specialist glass and new forms of glazing. He also mentioned a similar problem with chemicals covered by the REACH certification and testing process.
As a 30+-year veteran of the industry, Dean Averies, Director, Beard Construction, said, “I’ve been through some boom times and some recessions, but I don’t ever recall being in this situation where supply and demand is so out of balance.”
Averies cited an unusual example of issues with cement, where it is not the material itself in short supply, but it’s the plastic packaging (which comes from China). A fire in a factory in China had a major impact on the supply of plastic packaging, as did the weather-related problems in Texas earlier in 2021; some of the ingredients that go into plastics are produced in Texan factories that had to shut down.
 Creative options
Unlocking the potential of existing buildings was the focus of the materials shortage approach presented by Rachel Hoolahan, Architect, Orms Architects. Although she admitted that not all buildings could be reused, she stressed the importance of evaluating the reuse option at the outset, particularly in terms of carbon impact.
While material reuse is not a solution to supply issues, Hoolahan stated that it could help. “We have got to stop pulling virgin materials from the earth, and we need to move towards a circular economy,” she added.
One way forward for materials reuse is a Material Passport. Hoolahan explained how the process of deconstruction could be based on the concept of viewing a building as a potential material bank. Rather than seeing an existing building as a structure, she suggested evaluating it as “...a repository or a stockpile of valuable, high quality materials that can easily be taken apart and recovered.”
Obstacles to reuse include cost, current design and construction processes and lack of knowledge about - or trust in - the reused materials. The Material Passport would address the trust obstacle by providing information about key aspects of the product. A database of products with Material Passports would make it possible for designers to base their projects on what items are available.
