Company fined after falling scaffold clip hits pedestrian

0

A scaffolding company was sentenced today for safety breaches after a scaffold clip fell approximately 20m (60 ft.) and hit a member of the public walking below.

Westminster Magistrates Court heard that, on 20 March 2017, the injured person was walking along Upper Street in Islington, London when he was hit on the head by the clip. He sustained numerous cuts to his head and face, a broken nose and a severely bruised skull. The Health and Safety Executive (HSE) prosecuted the firm over the incident.

Alandale Plant & Scaffolding Ltd of Beckenham, Kent pleaded guilty to breaching Section 3(1) of the Health and Safety at Work Act 1974. The company was fined £160,000 and ordered to pay costs of £7,059.08 and a victim surcharge of £170.

Speaking after the hearing, HSE inspector Sarah Robinson commented: “This incident could so easily have been avoided by simply carrying out correct control measures and safe working practices.

“On this occasion the company did not follow their own risk assessments or method statements.”

Cutting Roof Timbers – Capel Build #4

0

This is the fourth part of our second building project series on Skill Builder where we look at cutting roof timbers.

The Capel Build sees carpenter and builder Robin Clevett renovate and extend an unusual property in Surrey.

In Part 3 we saw Robin getting the timbers together, in this next instalment we see him get stuck into the post and beam construction.

Robin discusses some of the challenges associated with cutting roof timbers for a timber frame home and shares some useful tips for making the job easier.

“It’s a little bit fiddly when you’re marking out rafters on your own, but it’s all about technique,” explains Robin.

For example, Robin has two circular saws so he doesn’t have to constantly walk back and forwards with one.

We love watching a craftsman at work and the gale-force winds didn’t stop Robin working or us following him for the day. We hope you enjoy this update on The Capel Build.

Why did we make an impact driver test?

On Friday 9th February we released our showdown of eight of the big players in the impact driver arena to help you identify the best impact driver for your needs.

Roger Bisby put drivers from Bosch, Dewalt, Hitachi, Hilti, Makita, Metabo, Milwaukee and Panasonic through their paces.

Explaining the thinking behind the latest test, Roger comments: “We set this test up with different machines because most tests run near identical machines against each other and it tells the viewer nothing.

“We wanted to find out just how different the machines could be and run them across a variety of tasks. We also took them out on site to do some real work.

All the machines were phenomenal but some more so than others.

“One of the challenges was finding a consistent test. Some people said concrete is better than oak in this respect but we found that some impact drivers stripped the concrete thread more than others so we came up with a solid piece of seasoned Engish Oak. To give you some idea of how hard this is, we couldn’t even get the screws to turn with a socket set. All the machines were phenomenal but some more so than others.

“We put the test out there and we tried to be fair but some people are questioning the results and it looks like a re-run may be needed. We are asking viewers for suggestions on how to make it fairer.

Roger concludes: “Everyone has been asking us for this test and, to their credit, the manufacturers were all up for it. The DeWalt was impressive, no doubt, but is the difference enough to make you abandon your favourite brand​?”

The recent introduction of quiet fluid drives into impact drivers which have traditionally been notoriously noisy is also worth highlighting. In certain areas where noise is an issue and considerate construction is a priority the quiet fluid drive is likely to be a real bonus.

As well as the impact driver test conclusion above, links to the full reviews of each impact driver are listed below.

As always we would love your feedback and suggestions for the next test – please share your thoughts on our YouTube channel or in the comments below.

SGN partners with SmartWater to prevent tool theft

0

UK gas distribution company SGN has teamed up with SmartWater to combat the growing trend of tool and van theft.

The utility provider, which provides gas to 6 million homes, has applied SmartWater’s forensic traceable liquid to all its liveried vehicles and the tools and equipment onboard. The forensic formula contains a unique identifying code, like DNA, registered to SGN.

If SGN assets are then stolen and later recovered, irrefutable ownership can be established, and the offender can be returned to the scene of the crime.

Senior Security Manager Andrew Sindall said: “SmartWater is a global product and has been used extensively in the UK and abroad to tackle theft.

The deterrent power of this well-known brand is recognised in the criminal fraternity. Academic studies have shown that 74% of criminals, when interviewed, would not go near or target anything displaying SmartWater signs.

academic studies have shown that 74% of criminals when interviewed, would not go near or target anything displaying SmartWater signs

“We have already been working with SmartWater for several years around the prevention of metal theft from our sites. As a result, we’ve seen a decrease in the number of reported incidents. Given these successes, we were keen to extend our partnership further to provide even greater protection for our vehicles and high-value tools and equipment.”

SmartWater CEO and Co-Founder Phil Cleary added: “Tool and van theft continues to be a major issue for much of the UK, and so I commend the positive steps taken by our clients to try and reduce the risk to their assets and commercial vehicles.

This latest initiative is a great example of our two companies’ strong, proactive working relationship. It is a testament to the value of the SmartWater brand as an effective and proven deterrent.

Consequently, a powerful warning has now been issued to thieves looking to target SGN assets, as they are unlikely to challenge our 100% conviction rate, allowing SGN to continue to deliver key services uninterrupted.”

Adrenaline Boost Meets Comprehensive Safety

0

On a treasure hunt with the smallest submarine in the world – and networked power tools from Bosch.

He wears his passion on his sleeve like a tattoo: Andi Peters, wreck diver and treasure-hunter, owns the smallest submarine in the world. It is 2.80 m long, 80 cm high and you squeeze into it as if it were a tailor-made suit.

From the access hatch, which he climbs through like a contortionist, to the emergency exit via the dome, the front window on the submarine, which can be opened using a 3.6 V cordless screwdriver following pressure equalization, Andi Peters has thought of everything, right down to the smallest detail.

“As an adventurer, you take many risks, but the fun stops when it comes to safety. The same is true for the tool that I have to rely on,” he explains. His work as an independent treasure hunter has a solid basis: He is a trained metalworker, Chief Mate with a captain’s license and he also reports on his travels into the deep as an author and through TV documentaries.

He knows the adrenaline boost that one gets from adventures just as well as he knows the dangers that arise under water: Drifting fishing nets and poor vision, particularly in the North Sea, which are part and parcel of his chosen line of work.

In these murky waters, as the fishermen call this turbulent, cloudy sea, you can barely see your hands in front of your face. And then there are the tides, with their dangerous currents.

There is usually only a very narrow window of time for the dive. This was also the case for his greatest find – the wreck of the “German Titanic”, the steamer “Cimbria”, which was on its way from Hamburg to New York on an icy, foggy night in 1883 when it sank near the North Sea island of Borkum with more than 400 passengers on board.

Stories such as these are equally as thrilling for Andi Peters as his regular training or those leisurely dives where he can simply enjoy floating along the sea bed.

Cordless drill/driver and angle grinder for preparing the dive

A training dive is also part of today’s program. Depending on the water and the current, he also involves two safety divers, who accompany the submarine.

The crew also includes two indispensable tools: The GSR 18 V-60 C Professional cordless drill/driver and the GWS 18 V-125 SC Professional cordless angle grinder.

Both devices belong to the series of networked power tools from Bosch for professionals. “These are exactly the tools that I need for my preparations.

I can use the cordless drill/driver to secure the oxygen bottles to the outer wall, for example. The angle grinder is my all-rounder: For cutting rusty screws on the transport trailer or sanding the blades on the drive rotors so that they are perfectly positioned.

If you have these two tools with you, you can repair and adjust everything, independently of power sources, which you do not have access to when on a beach,” explains Andi Peters.

Everything under control thanks to networking and user protection

The topic of safety is always a priority for the treasure hunter. He pays particular attention to the user protection offered by the tools. “The emergency stop function on the angle grinder is a super, super, safety feature,” he explains.

The Bosch GWS 18 V-125 SC Professional is the world’s first angle grinder with “Drop Control”. If the tool falls, this function immediately switches it off as soon as it hits the floor.

The cordless angle grinder also has “KickBack Control”: If the integrated sensor detects a sudden blockage of the angle grinder – for example if the disk jams – the integrated sensor immediately switches off the motor. And the tool has lots more to offer.

The angle grinder is also the first of it’s kind to come with a connectivity function. Thanks to an integrated Bluetooth module and the “MyTools” function in the Bosch Toolbox app, it can be connected to a smartphone – for example, to personalise it or call up tool information.

You can also use the networking to receive troubleshooting tips, for example, if a tool switches off because it has overheated. And you can adjust the tool settings to suit the relevant application.

These functions also include soft start, which Andi Peters selects so as not to start “too hard too quickly” when working on the rotor blades. He can also see the tool status, such as the battery charge status, directly on the tool via the multi-functional user interface. In this interface, he can also easily preselect the speed.

Time to dive

One last safety check with the accompanying divers; the route and the rescue chain (just in case) are discussed – diving involves teamwork.

Andi Peters warms up and starts up the submarine’s ventilation system so that the carbon dioxide filter will work correctly underwater.

He then agilely enters the small submarine, wedges an emergency oxygen bottle between his legs and starts up the motor. He secretly dreams of a submarine version 2.0, which would have a comfortable seat and a diving depth of 300 meters.

He already has the right tool for the job. But first: Dive, lie at the bottom of the sea, and observe the crabs and jellyfish. “That is pure pleasure. Money can’t buy the things that I get to experience,” he says as he closes the hatch.

BS 8612 – A Watershed For Pitched Roofing

Redland – the company that invented dry-fixed roofing systems, with patents dating back to 1966 – has welcomed the introduction of BS 8612 Dry-fixed Ridge, Hip and Verge Systems for Slating and Tiling, published on January 31st.

The new standard is a product specification which frames minimum performance requirements for dry-fix roofing components: establishing that they are both fit for purpose and are delivered with sufficient information to ensure correct installation.

The introduction of BS 8612 is a response to an increasing number of, particularly, dry verge failures; primarily because of installation errors, but also contributed to by product design.

In 2011, NHBC analysed its claims figures and discovered that 60% of them were related to roofs and of all roof-related claims, over half involved mortar which led to the changes in NHBC guidance in 2012

Dr Kevin Ley, Technical Manager of Redland, says: “Since BS 5534: 2014 – which brought about a step-change in the requirements for fixing of pitched roofs both for roof tiles and ridge, hip and verges – we have seen an acceleration in the move away from traditional mortar fixing to modern dry-fix.

Unfortunately, the resulting increased demand for dry-fix products and a lack of standardised performance requirements allowed products of questionable fitness for purpose to enter the market. The resulting problems meant there was a significant risk that past mistakes concerning mortar fix failures would be repeated”.

Many developers have migrated to dry-fix systems as they are far faster to fit than double-fixed wet systems but poorly performing and poorly installed dry fix systems have been leading to roofs with problems

Though dry-fixed products have been on the market for decades, demand has burgeoned over the last five years. As a result, there’s also been a growth in the number of companies supplying lower cost, and often lower quality, products. The switch from traditional wet fix to dry fix was initially driven by changes to NHBC guidance. In 2011, NHBC analysed its claims figures and discovered that 60% of them were related to roofs and of all roof-related claims, over half involved mortar.

This led to changes in NHBC guidance in 2012 which said that all bedded ridge and hip tiles had to be mechanically fixed, and then ultimately to the 2014 revised version of BS 5534 Slating and Tiling for Pitched Roofs and Vertical Cladding – Code of Practice which standardised these changes.

Problems include ridge and/or hip tiles blown off by the wind; dry verges hanging from roof edges, or unsightly black staining down gable-end walls

As a result, many developers have migrated to dry-fix systems as they are far faster to fit than double-fixed wet systems. However, the purchase of poor performing dry fix systems, or the failure to install quality components correctly, leads to roofs with problems. For example, this may mean ridge and/or hip tiles blown off by the wind; dry verges hanging from roof edges, or unsightly black staining down gable-end walls due to verges which do not shed rainwater properly. The latter problem of verge failure to shed rainwater away from the wall at worst can lead to penetrating damp and compromise cavity wall insulation.

The introduction of BS 8612 is a response to an increasing number of, particularly, dry verge failures; primarily because of installation errors, but also contributed to by product design

Dr Ley concludes: “The publication of BS 8612, the first-ever product standard for dry-fixed ridge, hip and verge products in the UK, is, therefore, an essential and welcome landmark for the industry. Not only will it ensure that dry-fix design and installation standards are raised; but also that developers, contractors and building owners get the product quality and performance they deserve”.

How Secure is Your Van? – The Truth & Solutions

0

Skill Builder shares some essential information about van security and takes a look at the shocking vulnerabilities of the Ford Transit.

In this video, we visit Sussex Installations to get the ultimate low-down on van security and make Roger’s Vauxhall Vivaro more theft-proof.

After a recent break-in Roger was reassured to be able to upgrade the security on his van but ultimately we believe you shouldn’t have to.

Like many in the industry, we feel strongly that more needs to be done to prevent van break-ins and to help tradespeople protect their livelihoods.

We are baffled as to why van manufacturers aren’t prioritising van security? What we really need is a safe on wheels and most of us would be happy to forego other features if a van manufacturer could supply this.

Stronger punishment for perpetrators of tool thefts would also help – to this end carpenter Mark Riley has created a petition calling for greater penalties. Sign it here: https://bit.ly/2FxaH6w

We would love to hear your stories about van theft and any tips you have to counter the issue.

Carillion contracts worth 7.5 billion

0

As the economy continues to come to terms with the collapse of Carillion, the latest figures suggest that on the day of liquidation, the industry giant was the main contractor on 57 construction projects worth a total of £5.7 billion, including a £1.3 billion HS2 contract.

This latest information comes from construction industry analysts Barbour ABI, who outlined that ten of the 57 projects were each individually worth more than £150 million, such as the Royal Liverpool hospital and an Army basing programme in Salisbury worth £450 million and £340 million respectively. Carillion was involved in 16 framework contracts as part of a list of companies pre-selected or pre-qualified to undertake works for an organisation. These framework contracts are not included as part of the final 57 projects as there is no guarantee that they had won any work from the framework.

If the reason Carillion went bust was due to under-bidding then it stands to reason that the financial terms will have to be renegotiated. There is no doubt this will happen but will it happen quickly enough to save the many firms in the Carillion supply chain?

Commenting on these findings, Michael Dall, Lead Economist at Barbour ABI, said: “Carillion were deeply embedded within the construction industry – they were the second biggest contractor in the UK by revenue. Our records show that they were the main contractor on almost 60 schemes worth a total value of £5.7 billion. That is not to mention the plethora of other contracts where they were carrying out other construction roles.”

“The sector where Carillion had the largest presence was infrastructure – road and rail projects were a particular speciality for the firm. In addition, Carillion were in the process of delivering two new hospitals and were also responsible for various school improvement projects. What happens to these projects is a matter for conjecture. If the reason Carillion went bust was due to under-bidding then it stands to reason that the financial terms will have to be renegotiated. There is no doubt this will happen but will it happen quickly enough to save the many firms in the Carillion supply chain?”

Bricky and chippy shortage reaches record high

0

Two-thirds of those running small and medium-sized (SME) construction firms are struggling to hire bricklayers and carpenters as construction skills shortages hit a ‘record high’, according to the Federation of Master Builders (FMB).
 
Key results from the FMB’s latest State of Trade Survey, the quarterly assessment of the UK-wide SME construction sector, include:

  • More than two-thirds (68%) of construction SMEs are struggling to hire bricklayers and 63% are struggling to hire carpenters and joiners – the highest figures since records began in 2008;
  • The number of firms reporting difficulties hiring plumbers and electricians (48%), plasterers (46%) and floorers (30%) also reached record highs;
  • Construction SME workloads grew at a slightly slower rate than in Q3 2017, but new enquiries and expected workloads slowed more sharply; expected workloads among those firms building new homes showed a negative net balance for the first time since 2013;
  • Fewer construction SMEs predict rising workloads in the coming three months, down from 41% in the previous quarter to 38% in Q4 2017;
  • 87% of builders believe that material prices will rise in the next six months, up from 82% in the previous quarter;
  • Nearly two-thirds (61%) of construction SMEs expect salaries and wages to increase in the next six months.

Brian Berry, Chief Executive of the FMB, said: “Skills shortages are sky rocketing and it begs the question, who will build the new homes and infrastructure projects the Government is crying out for. The Government has set itself an ambitious target to build 300,000 homes every year in England alone.

“More than two-thirds of construction SMEs are struggling to hire bricklayers which is one of the key trades in the building industry. This has increased by nearly 10% in just three months which points to a rapid worsening of an already dire situation. What’s more, nearly as many are facing difficulties hiring carpenters and joiners.

“These figures are the highest we’ve noted since records began a decade ago. As a result, the wages for these increasingly scarce skilled tradespeople continue to rise sharply; that’s a simple consequence of supply and demand. This, coupled with the fact that small construction firms continue to face significant material price increases, will inevitably squeeze their margins and put a brake on growth.”

Berry continued: “The Government must take account of the worsening construction skills shortage with Brexit looming large on the horizon. The Prime Minister must ensure that the immigration system that replaces the free movement of people can take account of the particular needs of key sectors such as construction and house building. Without skilled labour from the EU, the skills shortages we face would be considerably worse, and it is not in anyone’s best interest to pull the rug out from under the sector by introducing an inflexible and unresponsive immigration system. On the domestic front and in the longer term, to ensure we have an ample supply of skilled workers in the future, the Government must continue to work with industry to set the right framework in terms of T-Levels and apprenticeships.”

Berry concluded: “The silver lining to current skills shortages among construction SMEs is that the numerous tradespeople and professionals, who may find themselves out of work following the collapse of Carillion, have a ready supply of alternative employers. The FMB is working with the Department for Work and Pensions and the Construction Industry Training Board to match-make ex-Carillion workers with small construction employers in need of skilled workers. We’re also working hard as an industry to re-home the 1,200 Carillion apprentices who are the innocent victims of the major contractor’s demise. It’s in everyone’s interests to ensure that these young people continue on their path to a rewarding career in construction.”

Safety Stand-Down to Cover Whole of Construction Sector

0

Following a successful launch in 2017, the first UK-wide stand-down for the infrastructure sector has plans for growth in 2018 with plant safety and mental wellbeing two key priorities for the coming year.

Last April more than 60,000 workers on more than 1000 sites took part in events to support Stop. Make a Change. The initiative saw sites, offices and production facilities stop work for focussed discussions on four key issues – mental health, fatigue, plant safety and respiratory health.

More than 50 clients, contractors and suppliers took part, with many making specific commitments to drive improved performance in the priority areas.

Following feedback from these companies, it has been agreed to expand Stop. Make a Change in 2018 to cover the whole construction sector rather than solely infrastructure. This is intended to increase the impact and share the best practice that has been developed more widely.

In a change to 2017, Stop. Make a Change events will now take place across a two-week period from 16-28 April, rather than a single day. This is to support organisations who faced challenges in standing down their entire workforce at once.

Construction Sector

A vote among those organisations that took part last year has identified plant safety and mental wellbeing as the two key priorities for 2018. The smaller number of priorities will allow organisations to provide more time to focus on these issues in detail during events.

Stop. Make a Change has been supported by CITB’s Structured Fund as part of Infrastructure 21, a Civil Engineering Contractors Association-led project to help ensure that civils suppliers are primed ready for expected growth in the sector in the coming years.

Companies from across the wider construction sector are invited to take part in Stop. Make a Change. Full details including joining instructions and useful resources can be found at www.stopmakeachange.co.uk

Banks Must Show Leniency to Carillion’s SME Supply Chain

0

Banks must show leniency to the thousands of SMEs in Carillion’s supply chain, according to the Federation of Master Builders (FMB).

Commenting on UK Finance’s announcement that the major banks and the Government are working closely to limit the impact of Carillion’s liquidation on small and medium-sized builders (SME) firms, Brian Berry, Chief Executive of the FMB, said:

“It’s absolutely critical that the banks give the innocent victims in Carillion’s supply chain as much leeway as possible in the short to medium term. We therefore welcome UK Finance’s announcement late this afternoon that lenders are putting in place emergency measures, including overdraft extensions, payment holidays and fee waivers, to ensure those facing issues relating to Carillion’s liquidation can stay on track.

“Leniency from the major banks will make all the difference to the thousands of firms in Carillion’s supply chain as to whether they survive its collapse, or follow suit. The construction industry is the cornerstone of the UK economy so it’s in all of our interests to do what we can to support these small companies and limit the domino effect that Carillion’s demise could have.”

Carillion collapse must be a catalyst for change, says BIFM

0

Following the news that Carillion has gone into liquidation the British Institute of Facilities Management (BIFM) has issued a statement stressing the need to learn from the event and to use it as a catalyst for change.

In its statement Carillion said:

The news that Carillion has ceased trading is both sad and shocking.

The clear priority is to ensure that the work the construction and services firm is contracted to do can be completed and the impact for the thousands of Carillion workers, as well as its customers and suppliers, can be minimised.

BIFM will be reaching out to its members affected by this development.  Chief Executive Linda Hausmanis has written to reassure the learners from Carillion currently studying for a BIFM qualification in Facilities Management that their situation is unaffected by the news and encouraging them to complete their studies as normal.

the case is already raising questions around the now established arrangements in our economy where outsourcing is a mainstay of so much public and private service provision

It is too early to draw conclusions about what the collapse of Carillion means for the wider outsourced services industry.  Beyond the widespread concern for the thousands of people directly affected that BIFM shares; the case is already raising questions around the now established arrangements in our economy where outsourcing is a mainstay of so much public and private service provision, not least facilities management.

The BIFM has already begun to reflect on the evolving landscape for FM.

Last week the Crown Commercial Service (CCS) published the first phase of a new £12 billion Facilities Management Framework.  The welcome intention behind the much-simplified process, expected to launch in May, is that more SMEs will enter the supply chain.  The inclusion of components such as ‘social value’ into tender specifications can assist firms who might otherwise fail where lowest cost is the primary denominator.  In the light of this week’s events especially, BIFM will be working with members to scrutinise the framework.

BIFM’s Spring conference Think ‘Beyond’ FM – Adapt or Disappear will explore the major disrupters in facilities management.  A dedicated session entitled ‘The Age of Uncertainty’ will focus on outsourcing and public private partnerships to understand how game changers, such as policy proposals to revoke PFIs or the impact from a market shock, are affecting facilities managers today; and how BIFM members can navigate the surest path.

Whatever the future, BIFM will be reaching out to its members to understand what is happening in their contracts now. There will be important learnings for our industry.

Linda Hausmanis said: “The news of Carillion is indeed a sad moment for all those affected.  BIFM’s immediate priority has been to reassure the learners from Carillion studying for qualifications in Facilities Management that their situation is unchanged. I want to encourage them to continue their self-development and I wish them luck.

“We can’t change what has happened; but we must learn from this event and use it as catalyst for change.  The case can and must be made to change from a model of service delivery that is driven by cost alone to one that is driven by value”.

What’s the Best Mix for Rendering?

Roger helps you get the best mix

The best mix for rendering depends on what you’re rendering on to and the golden rule is you never make the mix stronger than the material that you’re going on to.

For example, lightweight concrete block that’s 3.6kN so we don’t want a really strong mix for this because if the wall moves, which it will as you always get some expansion and contraction as the seasons change.

You don’t want the render to be the thing that stops the wall from moving otherwise the render will crack. If you’ve ever wondered why does render crack, often this is a reason.

Also if you put too much cement in render it shrinks back and it will crack. People don’t always believe that, lots of people do a 3:1 mix and say it’s nice and strong but that won’t stop it cracking because there’s no real tensile strength in it so there’s no point putting too much cement in.

Best Mix for Rendering

Why lime helps make the best mix for rendering

Instead, we make a 6:1:1 which is six parts of sand, one part of cement and one part of hydrated lime.

The sand must be plastering sand or rendering sand, not building sand – do not use building sand for rendering because it shrinks and cracks.

Sometimes you can add some building sand to the mix for the base coat but it shouldn’t be your primary sand. It’s important not to put more than one part lime to one part cement because hydrated lime won’t set on its own, you need the cement to help it set.

The lime does give the mix body and make it creamy and gives it a certain amount of elasticity so that if the building moves the render will go with it a bit and if you do get a crack the lime in the mix will move into the crack and re-calcify to some extent. In a way, it is self-curing and self rendering.

A lot of renderers don’t use it and prefer to use plasticiser which puts lots of bubbles into the mix which is a good thing but the lime is better as we demonstrate in this video.

Roger also discusses the best weather for rendering.

forbidden forest – September 2019

Too many young builders get caught in the ‘brand new transit van and nagging wife for a bigger house’ brigade and before they know it they’re working 7 days a week and ripping everyone off so they can take their spoilt kids on a dull tour of Disney Land because their wife thinks they’ll like them more. Well here’s a message to busy builders everywhere – forget Disney land and a dull pile of plastic presents: buy your kids some second-hand books to read as this’ll give them the best life imaginable, then work 4 days a week so you can spend time with your family as opposed to throwing sh*t on walls all day while listening to talk sport and talking about talk sport.

stewie3ify – October 2019

I’ve got a house that’s been rendered on to concrete blocks and I’ve had quite a few long cracks I’ve had to chop the cracks out and patch them and this time I used plastering sand cement and lime I’ve been a plasterer for 16 years and the first thing I was taught when floating and rendering was the mix it’s important to always put lime in the mix never use building sand I’ve always done a 5:1:1 mix I hardly render these days but it’s fact to much cement and the wrong sand will make your render crack in time.

Fall Protection – Making the Complex Simple

0

Andrew Pass, Global Engineering Manager for Fall Protection Engineered systems at MSA Safety explains why he believes engineered simplicity is fundamental to success in fall protection and explains how this has driven the design of the company’s new V-Series range.

Fall Protection – A Tall Order

With new designs and modern substrates, fall protection systems need the agility to perform when working on different, often lighter and more flexible, materials. Product innovation means being able to re-engineer products and systems to meet these needs while still maximising performance.

Leaving nothing to chance

The basic rule underpinning fall protection is that nothing is left to chance. That means every new product or link in a fall protection system has to comply with stringent regulations, to ensure maximum safety.

When structural materials change, so too do the forces at play if someone falls. Fall protection technology needs to continuously change to reflect these altered circumstances.

The basic rule underpinning fall protection is that nothing is left to chance. That means every new product or link in a fall protection system has to comply with stringent regulations

It’s not just different materials that need to be accounted for, it’s also changing working practices. A good example of this is the transmission tower.

In the past, workers had to physically climb the structures to maintain them. Today, maintenance departments investigate and utilise MEWPs (Mobile Elevated Work Platforms) where appropriate, which need completely different fall protection solutions.

As these new solutions evolve it naturally means that more and more systems are being used for fall protection. This can lead to confusion when selecting an effective combination of products.

Plus there is the increased risk associated with choosing non-compatible products. For this reason our skilled engineers create solutions that, while meeting complex needs, are still simple to understand and use.

The new MSA Safety V-Series range of Personal Protective Equipment demonstrates our principle of simplification.

Individual V-Series elements (harnesses, lifelines, helmets etc) work seamlessly together, and also with many of our other products, such as our Latchways engineered lifeline range. This simple ‘ecosystem’ is both easy to use and understand and provides one of the highest levels of protection available.

When we began to develop the V-Series, our priority was to use intricate engineering to enable customers to make a simple choice. We considered each and every fall protection requirement and looked in detail at how, why and where a system would be used.

It’s only by truly understanding the engineering complexities of fall protection needs that you can design a purposeful solution.

Solutions designed to meet a need

Our specialist engineers work closely with our customers in order to appreciate the detailed needs of the application rather than starting from the perspective of providing a solution that is in search of a problem.

To ensure we deliver truly great products, we have engineers dedicated to specific industries, for example, offshore wind farms. If you have a Self-Retracting Lifeline out at sea, how do you reduce the time and cost needed for the repairs?

The solution we found was to engineer products that can be serviced in 15 minutes on location. This meets a real user need that can only be fully understood by experiencing the environment first hand.

We take a lot of inspiration from other industries. Take automotive for example – in Formula One racing, safety is paramount and racecars are built with the most intricate, detailed engineering you can image – you of course can’t see that detail in the final car.

Fall protection is the same, it is developed around the most advanced engineering, yet customers ultimately get a simple, easy to use product.

Setting the standard, looking ahead

Fall protection standards are evolving at pace and MSA is involved in keeping that impetus going. Our UK Centre of Excellence and the Global strength of the MSA brand help us lead the way in terms of developmental and batch performance testing.

Even products launched 20 years ago still exceed the standards and test requirements required today.

In many ways, everything we do at MSA Safety is about taking the complex and making it simple. Precision engineering, sophisticated enough to do the work for you.

Innovation – learning from other industries and pushing the boundaries. And of course, testing above and beyond the latest standards.

When it comes to fall protection, ongoing evolution is imperative. Materials, designs and the built environment change constantly and this calls for a continuous cycle of newer and better products.

All of these have engineered simplicity at their heart – simplicity of use, simplicity of choice, simplicity of peace of mind. It’s what gets workers safely home to their families every night.

It’s what V-Series is all about. And it’s our message to the industry – get your engineering right, and everything else will fall into place.

Worker Killed Falling Through Skylight

A company has been fined after an employee died following a fall through a skylight.

Leicester Crown Court heard how the deceased was working with another employee on the roof, re-siting a heater and new chimney flue when the incident occurred.

He suffered severe injuries and died from these injuries approximately 6 months later.

An investigation by the Health and Safety Executive (HSE) into the incident, which occurred on 31 October 2014, found that the work at height on a fragile roof was not appropriately planned, supervised or carried out in a safe manner.

IKO-Design Ltd of Parker Drive, Leicester pleaded guilty of breaching Regulation 4 and Regulation 9(2) of the Work at Height Regulations 2005 and have been fined £100,000 and ordered to pay costs of £35,000.

Speaking after the hearing HSE inspector Michelle Morrison said: “A well-planned job would have identified the risks from working on a fragile roof so that steps could have been taken to prevent the risk of anyone falling from height. This tragic incident was entirely avoidable if appropriate controls had been put in place.

“Proper precautions should be taken when working on roofs and near fragile skylights, even for short-duration work. Companies should be aware that HSE will not hesitate to take appropriate enforcement action against those that fall below the required standards.”

Bosch launches thermal camera

0

Bosch Professional has added a high-quality thermal camera to its measuring device range.

Its development is said to draw on the manufacturer’s deep understanding of practical problems faced by electricians, plumbers, builders and other trade professionals. The Bosch GTC 400 C Professional Thermal Camera is designed to bring competitive advantage to their businesses at an affordable price.

Multiple uses
It is designed for numerous applications, including installation and maintenance of heating, air-conditioning, electrical systems, windows, drywalls and building insulation. Just point the device at the work area to quickly gain a clear and reliable picture of the conditions you have to tackle. Its measurements, which include thermal images, visual images and temperature values, accurately show the pattern of heat distribution across the room or feature surveyed.

The thermal camera will reveal, for example:

  • Locations and courses of cables and heating pipes in walls and floors
  • Sources of draughts, dampness, water intrusion and pipe leakage
  • Weak points and overloads in electrical installations
  • Condition and effectiveness of heat insulation
  • Functionality of heating systems, and presence of radiator vents

Clarity
Issues which are difficult or impossible to see with the naked eye become clearly evident through high-resolution coloured pictures which are easy to interpret and demonstrate to your client. Visualisation is exceptionally sharp thanks to high pixel counts.

The device is equipped with a visual camera as well as an infrared sensor. This allows a thermal image to be easily superimposed onto a photo of the workplace, helping to put the data into context.

Speed
Bosch connectivity enables rapid transmission of images and data, wirelessly, to your smartphone or tablet, via the thermal camera’s inbuilt WiFi Hotspot and the Bosch Measuring Master app. You can share them immediately with your client, even while you are still on site. The device also has a micro USB, through which you can quickly move those files to your computer, using GTC transfer software, and on to your client in a report format.

The Capel Build Part 3 – Timber Frames

0

This is the third part of our second building project series on Skill Builder. The Capel Build sees carpenter and builder Robin Clevett renovate and extend an unusual property in Surrey. In this episode we look at the timber frames.

Robin has now taken delivery of the timber frame which was a day’s work in itself as some of the timber beams were huge. All of the timber came loose and everything was assembled on site.

Robin explains why it’s critical when building a timber frame home to set everything out perfectly and repeatedly checking everything, right from positioning the sole plates and checking the corners.

Robin is pleased with the quality of the timber frame as most of it fitted together perfectly. There were a couple of minor issues with four of the trusses but within 24hours or discovering the issues the manufacturer had made new ones, delivered them to the site and taken the old ones away so it didn’t hinder the build. The glue laminated beams were good fun. The joints were put together using a combination of Simpson Strong Tie products including the TUBSR Concealed Beam Hanger and the TU28 Concealed Beam Hanger which offer a completely invisible assembly.  It is a butt joint which will offend some purists who would like to see some tennons into those posts but the key thing is that it works and makes a strong joint.

Robin talks through some of the installation process which includes:

TU28 Concealed Beam Installation

  • Make a vertical notch in the joist end (width 6mm for TU12 and 9mm for TU16 to TU28),
  • Mark the position of the dowels on the joist before drilling holes – diameter of the hole according to the diameter of the dowel
  • Insert the top dowel in the joist
  • Route a  6mm deep pocket in either the joist end or the header. This is not compulsory, but is  improves the aesthetic of the connection making it tight to the post.
  • The hanger is screwed into the post and the joist is lowered onto the hanger.
  • Hammer in the stainless steel dowels

TUBSR Concealed Beam Installation

  1. Make a vertical notch in the joist end (width 6mm for TU12 and 9mm for TU16 to TU28),
  2. Mark the position of the dowels on the joist before drilling holes – diameter of the hole according to the diameter of the dowel
  3. Insert the top dowel in the joist
  4. Route a  6mm deep pocket in either the joist end or the header. This is not compulsory, it is used to improve the aesthetic of the connection
  5. Fix Install the joist onto the concealed beam hanger by hooking the joist onto the concealed beam hanger.  Top dowel hooks into slotted top hole on the concealed beam hanger.
  6. Install reamining dowels.the concealed beam hanger to the header with nails or screws

The next job for Robin is cutting the rafters and pitching the roof. Subscribe to the Skill Builder YouTube channel to stay up-to-date with this project.

What Will The New Year Have in Store for the Construction Industry?

0

Ian Anfield, Managing Director for construction audit and contract provider, Hudson Contract, shares his construction industry predictions.

“This time last year, I shared my thoughts on what would dominate the construction agenda in 2017. Some of the observations I made, such as Brexit being linked to skills shortages, were fairly safe, while others, like losing one of the major contractors due to decreased investor confidence, were a little more risky.

“Unfortunately, I imagine Brexit will continue to be blamed for every ill running through 2018, and Carillion limps on despite being morally and financially bankrupt.

At the moment, the company is being propped up by government contracts but surely this can’t spoil my predictions again and continue into 2019 – I foresee an end to Carillion’s long and painful death by June 2018.

As predicted last year, the cost of materials will continue to rise through 2018, the oil price, demand and poor old Brexit being blamed as the main drivers.

“As predicted last year, the cost of materials will continue to rise through 2018, the oil price, demand and poor old Brexit being blamed as the main drivers.

“This time last year, I projected that subcontractor rates would climb by 3% and in fact they went up by 3.8%, which is above inflation.

Therefore, unlike the rest of the UK workforce, if you believe government figures, on average, self-employed construction workers are better off now than they were 12 months ago.

Let’s hope it carries on and go for a prediction of another 4% next year taking the average earnings to £870 per week.

“As expected, the government has made lots of noise about penalties for land banking and relaxing planning laws, but ultimately the housebuilders will continue to build at a pace that minimises their risks and maximises their profits.

Reaching the government target of building 300,000 new homes next year will depend on how many schemes are designed to lend money to people who can’t afford to borrow it, rather than government policy on affordable homes, or the new City and Metro Mayors building a few council houses here and there.

It looks like the crash of 2008 is long forgotten and we may be building our debt pile ready for the next one.

“The London property bubble continues to float and will do so throughout 2018 as long as the Conservatives cling to power.

I have heard from a very good source that the foreign investors, who buy London property for their retirement pot, are far more worried about the damage Jeremy Corbyn and Labour could wreak on the economy than they are about Brexit.

And the banks are setting up satellite offices in the EU rather than moving lock, stock and barrel, so no shortage of potential purchasers to buy up the flats around the fringes.

Offsite construction is the new buzz for policymakers and commentators who seem to think we have never tried it before, or this time it will work much better and be more efficient

“Offsite construction is the new buzz for policymakers and commentators who seem to think we have never tried it before or this time it will work much better and be more efficient – and maybe they are right, we will have to wait and see, but I doubt 2018 will see a huge shift mostly because the cash-flow system does not work for heavy factory based outlay, and consumers are sceptical.

“Payment terms should be top of the agenda but with the government’s Construction Leadership Council dominated by major contractors and the consulting engineers who work with them, nothing significant will change in 2018.

“The most disappointing part of reading back through last year’s predictions was seeing the hopeful words around ending the CITB levy.

Despite the CITB being the most toxic brand in construction – hated by those who are forced to pay a levy under the threat of legal action and who get no help with training in return – the government seem to like them and look set to give them another 3 years to ‘reform’.

“In 2018, Hudson clients will continue to create their own success despite government policy rather than because of it, and the freelance builders who sell their services under Hudson will crack on and continue to out-perform the rest of the economy in terms of income.”
