THE SARNZ PLATFORM | SPRING 20183

FROM THE GENERAL MANAGER Spring 2018

Since our last issue a lot has changed! Nikki and Bridget have left the office, Graham as taken a step back, you’ll still see him around the place but in a different capacity focusing on getting our voice heard more on a national level. Trina and I are new to the office and have big plans in store, many of which have already started to come in to place. The biggest thing to note is the new website where more and more of what SARNZ offers is being put online for speed improvements and to increase our ability to offer you more. A big focus for myself, leading SARNZ has been delving into what it truly means to be a SARNZ member and how can we build on this and then market it to our clients so that we are the only choice, how can we get more involved with local communities so what we do and who we are is not a big question mark, how can we increase the recruitment pool and so many more exciting things. A massive part of this requires your input and feedback so please at any point get in touch if there is something you want us to focus more on, assist you on or promote more of.

We started August off with a bang! Our Diversity 2018 Conference was the biggest and best yet, we heard from some great speakers and began to delve into the ideas around what is diversity and how can we better work towards diverse work culture. We also touched on youth employment, this is our future. Giving youth, especially local youth the opportunity to be in an environment where they are nurtured, coached and given guidance will equal long term business success and this is something I will continue to promote and educate on as it is the way forward for us. Thank you once again to everyone who attended and supported our conference and a special thanks to our Gold and Silver sponsors as well as our associate members who went the extra mile to provide us with the tools necessary to pull this off.

Our next Platform edition will be the Summer edition. I am continuously evolving our marketing materials and communication to you all, so it may again look different. What I would really love is more profiles on people you think really make a difference in your workplace, feel free to send these through to me and we can look at putting something together for the next Platform. Our next magazine will also have a thorough breakdown of all the new features of our website. If you have any issues or questions please get in touch with me.

Thank you for the feedback given post conference, I am using this to ensure our next conference is even better and covers the issues you want it to.

Thank you all for being so welcoming!

Jessica

Technical Report: Environmental Loads on Scaffolds By Graham Burke

Over the last year there have been some high profile scaffold failures due to weather events in NZ. There have been many more that have not made it to the media. Fortunately, there have not been any serious injuries resulting from these incidents, but any one of them could have resulted in serious harm or a fatality.

SARNZ and WorkSafe have made presentations in Auckland, Wellington and Christchurch to highlight the problems but there is still a major issue with scaffolds being erected with no regard to the effects of weather on the scaffold while it is in place.

All scaffolds, no matter the size or complexity must be designed to allow for the dead loads and live loads imposed on them. Planks and other decking components must be lashed or fixed to the scaffold and other components such as toeboards must also be secured. Loose materials must not be left on the scaffold if they can be dislodged by wind or earthquake.

Dead loads (Or self-loads) are made up of all the components and accessories which are part of the scaffold structure, including:

• all structural components, platforms, guardrails and toeboards.• debris netting, sheeting, shrinkwrap or other scaffold wrap.• ballast or counterweights.• hoists, suspension and secondary cables and power leads on suspended scaffolds.

Live loads are made up of duty loads, environmental loads and impact loads. These may act individually or in combination.

Hobsonville Point, Auckland 2018


Duty loads are comprised of people, equipment and material stacked on the scaffold. Duty loads are rated either light, medium, heavy or special and should be managed by the user of the scaffold as detailed in the handover certificate. The scaffold company and the scaffold user should ensure these loads are incorporated in the design of the scaffold and managed throughout its use to prevent overloading.

Environmental loads are made up of the forces imposed on the scaffold (And any material stacked on or fixed to it.) by wind, rain and earthquake. These forces cannot be controlled and must be calculated to allow for the worst that is likely to be expected. Impact loads are short sudden loads that occur when the scaffold is struck by loads being dropped onto it or sheeting billowing and pounding.

Wind loads are produced by the flow of wind around the scaffold structure. The magnitude of the load will be determined by the height and shape of the structure, maximum wind speeds, terrain and location. Calculating expected wind loads is complex and must include factors of safety which will consider the levels of importance of the structure and potential outcomes of a failure.

Depending on the shape of the structure, wind direction and location, wind loads may act on the structure as pressure (Pushing onto the structure) or suction (Pulling away from the structure). In some cases, such as a temporary roof, the structure may have pressure on one side and suction on the other. This may amplify the wind loads and should be considered when designing bracing, ties and ballast.

Central Auckland 2017




Rain can increase loads on scaffolds due to soaking into planks and stacked material, and pooling in packaging or in sheeting. There have been incidents where roofs have collapsed because rainwater has pooled in shrinkwrap. Once pooling starts, the wrap will stretch and the amount of water trapped can increase rapidly, potentially leading to failure of the structure. Rain can also destabilise the scaffold foundation by either washing away material at the base or soaking in and weakening the soil.

This can be worsened when a scaffold is wrapped and the runoff is concentrated along the edge of the scaffold. Snow and ice can build up on platforms and roof sheeting. In areas prone to snow, consideration must be made of potential snow loads and methods to remove snow deposits. Flat roof pitches should not be used in snow prone areas.

Impact loads should be considered in the scaffold design. Common causes of impact loading are workers jumping from roof edges onto platforms, material being craned onto loading bays and scaffold hoists starting and stopping suddenly. Scaffold sheeting that billows and pounds on the scaffold structure creates a significant impact load and should be factored into the scaffold design. These loads can have a detrimental effect on ties and other structural members. Ties need to be positioned to ensure forces on the scaffold are transferred directly to them. Problems can occur when shrinkwrap is attached in large sheets and only fixed at the edges. This directs all the load to the structure at the lines of the sheet edges, as well as increasing loads due to billowing and pounding. Shrinkwrap or sheeting should be attached to the supporting structure at centres as close as possible, like the fixings on a permanent roof.

Loads should be calculated following the principles set out in Scaffolding NZ Good Practice Guidelines, AS/NZS 1576.1 Scaffold General Requirements, AS/NZS 1170.2 Wind actions, AS/NZS1170.3 Snow and Ice actions and AS/NZS1170.5 Earthquake actions. Loads need to be calculated to allow for events as below:

Wind Snow and ice Earthquake

1:100 1:50 1:100 (Source AS/NZS1576.1 General requirements)

Load combinations for strength limit states can be calculated as:

(1.5 x Dead Load) + (1.5 x Live Load) Live load includes duty, environmental and impact loads. (Source Scaffolding NZ Good Practice Guidelines) Cont...

Central Wellington 2010

Scaffolding NZ Good Practice Guidelines state that Screened scaffolds must be designed by a Chartered Professional Engineer, unless enough information is available using manufacturer’s information and known or calculated loads.

In effect this means that all the dead and live loads and their direction (Horizontal, upward and downward) need to be calculated. The scaffold needs to be designed to withstand all these loads with the combined factor of safety which will require calculations for the strength of the structure plus any additional ties, ballast and so on. Calculations may also be required to determine the strength of any supporting structure used to support or restrain the scaffold.

On a small and simple structure with little risk in the event of a failure, these calculations may be able to be made by a scaffolder or other competent person. Unless that person can competently carry out all the required calculations and design, a Chartered Professional Engineer (CPEng)must be used. In many cases, a competent person may provide a preliminary design and then refer to a CPEng to make or confirm calculations and design elements.

Scaffold structures must be fully completed and checked against the design before they are wrapped. This includes inspection by a CPEng if this is a requirement of the design.

WorkSafe Inspectors are asking to see calculations and designs for all wrapped scaffolds and temporary roofs and enforcement actions are being taken when these cannot be provided. If a scaffold company does not have the capacity to produce calculations and designs in-house, they should engage a CPEng at the planning stage of the project, before work begins erecting the scaffold.





Opinion: People don’t like “change”.

Or so I keep hearing.

Over twenty five years ago, my daughter Tayla was born. She is one of the best things that has ever happened to us, that was a change. And I loved that change.

A couple of years before that, my wife Peggy and I got married. That was a change. And we loved that (most of the time…)

More recently, in the last month, I started working with four new customers. That’s a change. And I loved that too.

So, I think “change” can be a good thing…

…if the BENEFITS are clear

In other words, people need to have a GOOD REASON WHY and SOME PROOF that it will work, those TWO things will help them with the reason WHY they should change what they are doing now!!

When you’re ’SELLING CHANGE’ to others, here’s a great way to do it. It’s a combination of some Harvard research, plus things I found worked brilliantly with our new customers.



There are five steps:

#1 Why it’s Needed

Start by explaining the key drivers for change.

In other words, why change is better than staying as you are. This will be one of or both of:

• the problem with the way things are now and/or• an opportunity to take advantage for the future

And, as you explain these, be crystal clear on how they impact the people you’re speaking to.

Remember: you want people thinking ‘I’ll be better off if we make a change’.

EXAMPLE #1: We are including scissor lifts in our product range because we are missing out on some suspended scaffolding work because it's to expensive for clients and we can’t always hire this equipment when we need it. The scissor lifts now have ground stabilisation hydraulic footings and can be left in place for extended periods which allows us to offer different scaffold building techniques and SAFER and FASTER methods for you our staff. You will get free training in a new technology which will be good for your career as well.

#2 The Future Vision

Now, explain what their world will be like after the change. In other words, be clear about the future state they can expect once the change has happened. Again, adapt your messaging so people understand how this future will benefit them personally.

EXAMPLE #1: This roof edge product will enhance our scaffold safety and make it safer for you and the public. This stuff clips on and SAVES you hours on any roof edge project. It is safer and faster and LESS lifting of heavy equipment is required. YOU WON’T be doing the old process of having to build a scaffold first.

Looking Ahead Profile - Maggie Myocevich South Pacific Scaffolding LTD

Maggie was a part of the Diversity Panel at our most recent conference. We thought she represented a lot of what the future of scaffolding is all about so wanted to get to know her better!

What do you like to do in your spare time? Spending time with my kids and going up home to Whangarei to enjoy the beautiful beaches, fishing or just a BBQ and beers with friends and family.

What is your role currently? I’m an elementary/general ticketed scaffolder in the role of team leader also health and safety rep for our company.

How did you get into that role? I believe that my hard work positive attitude and being a natural leader got me to the position I hold today.

What is an important lesson that you have learnt in your working life? Never to give up or be disheartened by anything or anyone just believe in yourself and keep pushing forward, if I had given up after being told something wasn’t going to happen I would have missed the opportunity to be where I am in a job I love.




What are a couple of major challenges you have faced? I’d say the biggest one would be building the strength physically to carry the scaffold around comfortably, also the initial worry of not being accepted in my role as I am female but that was overcome very fast as I have experienced nothing but support and positive prompting from all those I have come across.

What do you think a successfully implemented diversity culture/policy looks like in the workplace? A company/business/team that has overlooked what barriers and hurdles that having a range of people (race, religion, sex etc) may bring and has instead looked at the range of qualities they bring and works with them in helping them move forward in the workplace with the skills and experience they have. Helping everyone see positively the value of each other no matter what their race, religion, sex etc is.

What more do you think our industry should be doing to increase youth employment? Making it known that scaffolding/rigging are options for careers, attending careers days to talk to our youth about our industry, giving opportunities for work experience, the list goes on of the ways we can help our youth we just need to put into action our brainstorms of ideas.

What barriers do you see towards training in our industry? The high demand for scaffolding I believe puts a hold on those that want to start training and become qualified as the ones with ability to train are under pressure and busy reaching targets etc on jobs also the number of providers is low so the wait for starting courses can be lengthy.

If you could give one piece of advice to your past self what would it be? Go to the gym (joking) I would have liked to have found my career path earlier so I’d tell myself to stop wasting time looking in hospo/retail and just get out there in the “man’s world” where you think/know you can do well and do it.




Wind effects on Scaffolding and Rigging

Sydney-based Engineer for SafeSmart Access, Joseph Lo Presti is also a member of Standards Australia Joint Technical Committee BD-036, Scaffolding.

Joseph presented at the recent SARNZ conference on the effects of wind on scaffolding and rigging. While it induced some scratching of mathematical heads at times for some, many of the members found it extremely useful. Here is a summary of Joseph’s key points.

➢ AS/NZS 1170.2 gives requirements for wind load determination;

➢ The Design Wind Speed for most areas of New Zealand is 41m/s (154kmh), and 47m/s(169km/h) for Wellington;

➢ You only need one gust to bring down a scaffold;

➢ To determine the load on a scaffold tie, the wind speed must be converted to wind force asper AS/NZS1170.2;

➢ The higher you go on the scaffold, the stronger the wind becomes;

➢ The shape of the scaffold has an effect on the wind pressure;

➢ The shape of the structure immediately adjacent to the scaffold has an effect on the windpressure;

➢ Where the scaffold is located relative to adjacent structures has an effect on the windpressure;

➢ Geography affects the wind pressure;

➢ Time of year affects the wind pressure design;

➢ Project duration affect the wind pressure design;

➢ Scaffold importance affects the wind pressure design;

➢ Fully enclosed versus partially enclosed scaffolds have an effect on wind pressure and tieloads;

➢ The pressure on the enclosure at the corner of a scaffold can be twice what it is in themiddle of the scaffold;


➢ The pressure on the enclosure at the top of the scaffold can be three times what is in themiddle of the scaffold;

➢ Scaffold ties must be able to transmit the forces imposed by wind to a building or suitablestructure.

➢ Feeling lucky has no positive effect on reducing the wind pressure
