Wonder material Graphene could revolutionise the construction industry

April 25, 2018/0 Comments/in Home Page news feed, News /by joannevickers

Scientists say a greener, stronger and more durable concrete made using “wonder-material” graphene could revolutionise the construction industry.

Graphene is a form of carbon first reliably produced at the University of Manchester by researchers in 2004, work which led to two Nobel prizes. It is made up of a single layer of carbon atoms in a hexagonal lattice. Its structure gives it important physical qualities, including efficient conductance of heat and electricity and unusual strength.

A research team at the University of Exeter, which includes Cast Consultancy’s Dimitar Dimov, has developed a technique which uses nanoengineering technology to incorporate graphene into traditional concrete production.

The researchers say the new composite material is more than twice as strong and four times more water resistant than existing concretes, and has been tested using British and European industry standards.

The graphene-reinforced concentre material also reduces the carbon footprint of conventional concrete production methods, according to the University of Exeter scientists. They add that the technique could pave the way for other nanomaterials to be incorporated into concrete.

Dimitar Dimov, lead author, who works at the University of Exeter engineering department and with construction consultancy Cast, said: “This research is important as it can be applied to large-scale manufacturing and construction. The industry has to be modernised by incorporating not only offsite manufacturing, but innovative new materials as well.

“Finding greener ways to build is a crucial step forward in reducing carbon emissions around the world and so help protect our environment as much as possible. It is the first step, but a crucial step in the right direction to make a more sustainable construction industry for the future.”

Professor Monica Craciun, co-author of the paper and also from Exeter’s engineering department, said: “This new composite material is an absolute game-changer in terms of reinforcing traditional concrete to meets these needs. Not only is it stronger and more durable, but it is also more resistant to water, making it uniquely suitable for construction in areas which require maintenance work and are difficult to be accessed.

“Yet perhaps more importantly, by including graphene we can reduce the amount of materials required to make concrete by around 50% – leading to a significant reduction of 446kg per tonne of the carbon emissions.”

The paper, Ultrahigh Performance nanoengineered Graphene-Concrete Composites for Multifunctional Applications, is published in the journal Advanced Functional Materials.

The research was supported by the UK’s Engineering and Physical Sciences Research Council.

Cement-making accounts for 6% of global carbon emissions, and manufacturers must make sharp reductions if the Paris climate goals are to be met, according to the Carbon Disclosure Project, in a recent study.

UK Construction week unveils its Role Models campaign

April 18, 2018/0 Comments/in Home Page news feed, News /by joannevickers

UK Construction Week is launching a new initiative for 2018 to help the industry compete for talent and improve recruitment. It will do this by taking role models in the industry and elevating their profile and their story in a nationwide publicity campaign through trade and consumer media.

Nathan Garnett, Event Director for UKCW explains: “There are some amazing people working in the sector and their stories can be inspirational to others. So we are planning for UK Construction Week to act as a platform to do just that, inspire a new generation of construction professionals to join this rewarding and exciting industry.”

Role models will also be asked to take part in an outreach programme, going to colleges and schools in the coming months to talk to students and teachers at key stages of their education to explain what inspired them to choose construction as a career and bust any myths around the image of construction.

UK Construction Week is looking for professionals to apply or to be nominated. This is an opportunity for people to raise their own profile if they feel they deserve it, or for colleagues to nominate professionals they feel deserve recognition. This is a great chance for a company to raise its profile by showcasing its talent, as well as for unsung heroes to gain valuable encouragement, as well as help recruit a whole new generation of construction professionals.

This is aimed at all walks of the sector, whether you are a newly qualified apprentice, or someone who has transferred into the sector from the military or automotive industries. You could be working in facilities management, architecture, energy management, civil engineering, site management, bricklaying, digital construction, electro technical installation, roofing… the list goes on! UKCW want a diverse and representative selection to show the world the myriad of opportunities and talent the sector holds.

Successful UKCW Role Models will be asked to speak at UK Construction Week on the main stage or individual show stages, to take part in the UKCW student initiative, and they will be asked to write for the Construction Matters blog. They will also be invited to selected events in the coming months, as well as being VIPs at the main event in October.

Whilst all those selected in the group will gain significant profile from the campaign, there will be awards presented at the event itself to those who have been selected by the UKCW Advisory Committee to have been deemed the UKCW Role Models of the year. These will be presented at UK Construction Week on Tuesday 9th October in front of the journalists and industry VIPs.

Deadline for Nominations is Friday 27th April.

To enter or nominate, visit https://www.ukconstructionweek.com/news/show-news/2189-role-models and submit a 300 word max biog and short summary (under 300 words) on why you or your nomination should be selected.

Trade companies to support Macmillan men with cancer campaign

April 11, 2018/0 Comments/in Home Page news feed, News /by joannevickers

Macmillan Cancer Support is uniting with nine companies across the sector for their ‘Just Say the Word’ male cancer campaign.

Companies taking part include Benchmarx Kitchens and Joinery, CEF, ISG plc, Mace, Selco Builders Warehouse, telent Technology Services, Topps Tiles, Travis Perkins and Wolseley, who have joined forces with the charity to raise awareness of the impact of cancer on men and encourage those who need it to access support.

New Macmillan and Toluna research reveals that 26 per cent of tradesmen wouldn’t feel comfortable having a serious conversation regarding their health with their work colleagues.

Dave Watkins, 59, is an Associate Director at Mace and was diagnosed with prostate cancer in 2016. “When I was diagnosed, I initially found it really difficult to talk to others about my cancer and the emotional toll it was taking. Mentally, I found it difficult to come to terms with cancer and was in a dark place. But my experience really improved when I published my story on Mace’s staff intranet. My company and colleagues were incredibly supportive and helped my drive to stay positive.”

In its third year running, ‘Just Say the Word’ has had a great response previously and had inspired colleagues and customers to seek medical support.

Carine Jessamine, marketing director at Selco Builders Warehouse, said: “We are long-standing supporters of Macmillan Cancer Support and, through the amazing efforts of our staff, customers and suppliers, have raised over £500,000 for the charity within the last five years. We are all as motivated as ever to keep up the fundraising and we are also delighted to support the ‘Just Say the Word’ campaign to help spread key messages to people operating in the trade.”

Of the tradesmen that participated in the survey, 36 per cent of those with cancer also experienced depression, 40 per cent anxiety and 12 per cent shame, after they were diagnosed.

‘Just Say the Word’ runs from 23rd April to 6th May, and will have a visible presence in branches and sites of the nine participating partners. Posters and leaflets will be publicised, encouraging those with health concerns to get support. Fundraising for Macmillan will take place over the two weeks within the sector, raising money to help the charity provide support to people living with cancer across the UK.

Contractors who don’t pay on time to be banned from public works

April 3, 2018/0 Comments/in Home Page news feed /by joannevickers

Main contractors who do not pay their supplier promptly are to be banned from bidding for public sector contracts according to the Government.

The measure is among a package of proposed measures to help smaller businesses win public sector and government contracts.

Under the proposals, tier one contractors on government contracts, including construction projects, will be forced to demonstrate “fair and effective payment practices with their subcontractors”, otherwise they will not be allowed to bid for work.

Other plans include allowing subcontractors to have greater access to buying authorities to report poor payment performance.

Further requirements mean suppliers will have to advertise subcontracting opportunities via the government’s Contracts Finder procurement website. They will also have to provide the government with data showing how businesses in their supply chain, including small businesses, are benefiting from supplying to central government.

In addition, each government department has been directed to nominate a minister as small business champion.

No timetable has been given for implementation of the proposals.

Cabinet Office minister Oliver Dowden said: “This government is listening to the business community and is committed to levelling the playing field for smaller suppliers to win work in the public sector.

“We have set a challenging aspiration that 33% of procurement spend should be with small businesses by 2022 – and are doing more than ever to break down barriers for smaller firms. Small businesses are the backbone of the UK economy, and play a key role in helping us to build a strong, viable private sector that delivers value for taxpayers and jobs for millions all over the UK.”

Federation of Small Businesses national chairman Mike Cherry said: “Each year, the UK public sector spends over £200bn on goods and services from third parties. As such a large and prominent customer in the economy, the government has a pivotal role to play in demonstrating what it is to be a good client.

“It is right then that the government today announces, as part of a new package to boost SME procurement, that it will clamp down on poor payment practice throughout public procurement supply chains. Companies who pay late should not be rewarded with public sector contracts.

We need a robust public procurement process that holds larger companies to account for their payment practices.”

The Specialist Engineering Contractors’ (SEC) Group also welcomed the proposals. SEC Group chief executive Rudi Klein said that he was particularly pleased by the government’s promise to exclude poor payers from government procurement.

“We have been urging the government to introduce a yellow/red card system for a long time. The yellow card is a warning to improve payment performance and the red card excludes a continuing poor performer from bidding for government contracts for a period of 2 to 3 years.”

Rudi Klein added that if such a system had already been in place Carillion would have been excluded from government contracts.

However SEC Group believes that on payment security the government needs to go further and legislate to require that project bank accounts are put in place for all public sector projects. It also wants the government to back the Private Member’s Bill (now in the House of Commons) that will protect cash retentions.

“The Carillion debacle has revealed the appalling level of abuse heaped on construction supply chains,” Rudi Klein said. “We should also be considering the introduction of a statutory regulator to challenge the behaviour of large firms and, if necessary, fine them in the worst cases of abuse.”
