Looking at 好色先生TV鈥檚 headlines over recent weeks, you could be forgiven for feeling gloomy about the future of the construction industry. Social distancing rules have wreaked havoc on sites across the country and seem likely to stay in some form until a vaccine for covid-19 is found.

Stark figures from the Office for National Statistics for 4-17 May revealed that more than one-third of firms in the construction sector saw their turnover down by at least half compared with before the pandemic, while the Construction Products Association has estimated that sector output will drop by 25% this year.

In early June, two of the UK鈥檚 largest brickmakers announced plans to lay off a combined 600 staff, while housebuilder Taylor Wimpey reported its sales were down by 40% in the first five months of 2020, compared with the same period a year earlier. And just this week Travis Perkins has announced the loss of 2,500 jobs while Multiplex is consulting with staff, 20% of whom are thought to be at risk.

The furlough scheme may have staved off the worst for now, but in an industry famously dependent on cash flow, alarm bells will be ringing for many.

However, the gloom was not shared by a panel of industry experts who spoke at a recent webinar chaired by 好色先生TV鈥檚 editor, Chlo毛 McCulloch. Hosted in association with law firm Fenwick Elliott, the four tech specialists invited to discuss how the industry can use technology to plot a route out of the covid-19 quagmire were decidedly optimistic.

On the panel were Andrew Gamblen, digital manager at Willmott Dixon, Stacy Sinclair, head of technology and innovation at Fenwick Elliott, Sam Stacey, challenge director for transforming construction at government agency UK Research and Innovation, and Neil Thompson, digital construction director for the UK and Europe at consultant Atkins.

Each panellist delivered a short presentation about how the industry can adapt to social distancing rules. Where new procedures have been applied, the adjustment has in most cases been rapid. All the experts agreed that the success of many firms in keeping their operations going in the changed circumstances proves the sector鈥檚 ability to adapt. Far from crushing the industry, the lockdown has shown what it is capable of when pushed.

The problems

Construction鈥檚 age-old problems are well known, but the difficulties brought about by social distancing rules are entirely new. 鈥淲e really are feeling our way forwards,鈥� said Gamblen. 鈥淲e are in an unprecedented time of adversity, and we are learning a lot very, very quickly.鈥�

An immediate challenges facing firms is how to get productivity on sites back up to somewhere approaching sustainable levels. In many cases, the nature of building sites, with groups of workers required to be in close proximity, makes this almost impossible.

Indeed, Gamblen warned that no amount of new technology could enable a site to reach 100% productivity while social distancing rules are in place. He said: 鈥淯ntil that restriction comes off, it鈥檚 going to be very difficult to get back up to fully 100% because you will need more [workers] on site and it鈥檚 just not safe to keep that many people that close together.鈥�

Even the larger lifts at high-rise sites like Multiplex鈥檚 22 Bishopsgate, which shut down in March, could carry only about four workers at a time with all occupants standing 2m apart. Maximising output in these circumstances 鈥� and even when the 2m rule changes to 1m from 4 July 鈥� requires imagination and the streamlining of every process.

For Thompson, the loss of productivity is driven by behavioural as well as physical factors. He said: 鈥淚n locking people down and essentially working from home, we have slowed down that ability to share information. We have missed the opportunity for those serendipitous connections with people on building sites and in the office.鈥�

The process of decision-making when working at home, split across myriad interfaces and communication channels and all dependent on an internet connection, has dragged down productivity for offsite staff.

The solutions

For tackling this, said Thompson, 鈥渢here is no silver bullet. You can鈥檛 just go and buy one software package.鈥� Instead, to boost the efficiency of remote working, firms 鈥渘eed to start thinking about the user-experience design of making a decision, to reduce the digital touchpoints鈥�.

Preventing the spread of the virus on site will require the rapid deployment of contactless technology, according to Stacey. This includes face recognition systems as workers enter and leave sites and the use of digitalised, paperless processing of materials and waste logistics. Echoing Stacey, Gamblen said: 鈥淭hose that have undertaken this kind of digitisation previously are in a much better position to handle situations like covid.鈥�

Meanwhile, wearable tech installed with bluetooth location tags could keep a check on social distancing on site and alert workers when the 2m rule has been breached. Since the tags would have a record of where the wearer has been, Stacey said that this could also help with contact tracing.

Remote site visits using virtual reality headsets are another workaround. Site inspectors walking around wearing these headsets could soon be a common sight, according to Stacey, who said: 鈥淚t鈥檚 something that has always been desirable for the industry, and I think we鈥檒l see a massive ramping up of that.鈥�

Sensors embedded within concrete, a technology trialled at London City airport, could also be used to predict strength remotely and 鈥渕uch more accurately鈥� than existing methods, Stacey said. The tech could be combined with automated construction, a new approach that will be used by Land Securities to build its 拢70m office development in Sumner Street, London, due to start on site this year. It requires 50% fewer workers on site, while reducing capital cost by 10% and materials cost and waste by 30%. UK Research & Innovation hopes the approach 鈥渨ill be adopted much more widely across the industry in due course鈥�, said Stacey.

Without a doubt it is an opportunity to accelerate that culture change in the industry and embed better ways of doing things which will benefit us in the long term

But according to Gamblen, the proper use of tech that is already widespread has helped Willmott Dixon鈥檚 sites get close to pre-lockdown productivity levels. Planning software such as Nureva Span and Dalux has helped offsite staff get back up to speed, while projects that use BIM have taken 鈥渕uch less of a productivity hit鈥� than those that do not. Gamblen said: 鈥淭he understanding of a project by the use of 3D models and the ability to visually communicate the issues in a much clearer fashion than on 2D paper has really helped people come together.鈥�

Echoing Gamblen, Sinclair said the use of existing tech is 鈥渞eally helping with efficiencies and productivities鈥� for remote working at Fenwick Elliott. She has seen a 鈥渉uge increase鈥� in the adoption of tools for video conferencing, document sharing and other collaboration platforms in the legal sector, and believes this uptake is 鈥渂ringing about quite an exciting transformation in the legal industry. A real sea change in the way we are working.鈥�

Innovations adopted by the legal industry include the use of virtual breakout rooms while pursuing dispute resolution procedures online, with parties and their solicitors and advisers all dialling in.

Sinclair has also witnessed the kind of behavioural change of which Thompson spoke. It has been a 鈥渢ransformation of the mindset for people, of the companies, of the cultures and the workflows鈥�, she said. 鈥淭he legal industry is much more open now to these ways of working. This transformation is really going to open a door for innovation.鈥�

An opportunity

Despite the grim prospect of a global economic slump, a glimmer of hope for the UK economy is that the construction sector may emerge from this crisis more efficient and productive than it has ever been.

鈥淭his period is really starting to showcase things and show better ways of working,鈥� said Gamblen, adding that, post-covid, he expects 鈥渢here will be a huge focus on what actually brings value to the process and removing old and outdated processes that just are not needed鈥�.

It鈥檚 a challenge that all panellists agree is needed, and for which the industry is now ready. 鈥淧eople say that construction isn鈥檛 innovative: I disagree. It鈥檚 excellent at firefighting  鈥� it鈥檚 very good at dealing with an immediate problem,鈥� said Thompson.

鈥淭he construction industry often gets a bad rap for not innovating enough, but we鈥檙e fantastically good at solving problems quickly,鈥� Stacey added.

For Stacey, the time for reform has come: 鈥淲e have got this horrible crisis at the moment, but without a doubt it is an opportunity to accelerate that culture change in the industry and embed better ways of doing things which will benefit us in the long term.

鈥淚 think the net result will be a real step forward for the industry. I see this as giving a real boost to a lot of good things which are happening in the industry and, I hope, building up a sense of momentum around positive changes 鈥� with significant benefits for all the stakeholders involved in the built environment.鈥�
