Innovation Award Submission 2

Posted on : October 28, 2011

Corrugated – a New Revolution

Shed Roofing Profile Innovation Submission 2

This entry to the Shedeye Innovation Award is slightly different to the others entries regarding new products in many ways. This product involves the cladding of sheds, residential & commercial roofing and also is an innovation in the rollforming industry. This is not the site to explain the importance of this new release of a profile sheet and its implications to the roofing, heritage, architectural and other areas of the steel roofing and cladding industry. Almost a reinvention of an iconic corrugated iron from as early as 1829 to the present, this product actually provides a new release of an old product but with superior spanning capabilities being produced on a uniquely designed current rollforming line based in South Australia. The technology utilised and patented by Revolution Roofing will return the “common” corrugated iron roof sheeting back to a rounder, fuller, shapely and deeper profile based on the original 19th century Walker “Gospel Oak” profile.

Once again the supplier and innovator of this product has had a difficult time in choosing which of the three new TRUE OAK designs to enter in the Shedeye Innovation Awards?  Their choice was between three of these revolutionary new profiles, True Oak Mid, True Oak Deep and True Oak ‘5’ and details available on their website REVOLUTION ROOFING.

True Oak Corrugated

But of the three – True Oak Deep was selected because of its ability to be used in sheds as a 0.35BMT product as roofing as it is the only roofing rollformer that has span tables (not cyclonic) for this gauge of roofing.  With the same cover as everyone else, and still  at a cover of 762mm – it offers a product for the shed industry without change to the sheeting layout in regard to the cladding and roofing. The only adjustment will that have to be made is flashings (only minimal), as the depth of the rib is 21mm which is the very reason for the increased strength.  The features of True Oak Deep are 40% deeper and 40% stronger than standard corrugated with the ability to go down to 3 degree pitch in roof. The profile is much stronger underfoot than standard corrugated and less susceptible to denting by foot traffic.

Here are the Span Tables for True Oak Deep:

True Oak Deep Span Tables

The best explanation as to the details of this profile is best explained in the diagram below with the comparison of True Oak Deep and Standard Corrugated.

Comparison

That’s the technical stuff in brief – but a photo paints a thousand ribs or less and deeper!

To top this new innovation off, Revolution Roofing is offering a True Oak 20 Year Watertight Installation Guarantee. This back to back material, corrosion warranty is only available when the product is installed by a Revolution Roofing Licensed Contractor. Not only will this benefit shed suppliers, but also shed erectors once they become an approved Revolution Roofing Licensed Contractor and supplier. New roof photo of church here in SA.

Of all the aspects of this exciting design re-invention is probably the foresight of the founder (Mr. J. Easling) to undertake LCA of this product which is a first in the rollforming industry. This is now the only roofing profile to be under review for the GREEN TAG certification (by Ecospecifier) and will be available to all architects and engineers.

ShedSafe

Posted on : August 31, 2011

Does ShedSafe guarantee that your shed is in fact safe?

No. If your shed complies to The Building Code of Australia then your chances are far higher.

Does ShedSafe publish or contribute to the Building Code of Australia?

No. It copies large slabs of it in the “Design Guide Portal Frame steel sheds and garages”.

Does ShedSafe own or contribute to the AS/NZS 1170.2 2011 (Structural Design Actions : Wind Actions)?

No it was prepared by Joint Technical Committee BD-006 and was approved on behalf of the Council of Standards Australia on 23 November 2010 (published on 30 March 2011).

Who owns ShedSafe?

Shedsafe is owned by the ASI (Australian Steel Institute). The ASI was started using some large grants from Bluescope and Stramit.

Has ShedSafe ever rejected an applicant?

There have been no documented or rumoured rejections. Not bad for an accreditation that has to be earned and can’t be purchased.

Is ShedSafe Independent?

No.

How is Shedsafe funded?

Shedsafe is a commercial operation, that is used to fund the wages of the operators. ShedSafe charges the shed suppliers (those that have the software and organise the materials) to have engineers review three of their shed designs. Now of course these three designs are not their typical shed, they are over engineered and would be under the meticulous watchful eye of the shed suppliers engineers. This does have the potential to pick up glaring errors, but as far as being representative of the typical shed supplied, there is no way!
To further increase the money revenue potential, ShedSafe charges around the $500.00 mark to each of the shed sellers or distributors. How does this shed seller accreditation get earned? Sit a simple test, a pop quiz on the AS/NZS 1170.2. Again ShedSafe is earned not purchased. Rubbish!

Is ShedSafe a Brand or an Accreditation Scheme?

It is clearly a Brand. Accreditation is a quality assurance system of all processes that ensure the end product is safe and sound – the Shedsafe system of accreditation does not achieve this.

What do Shed Suppliers and Sellers think of Shedsafe?

They think it is a necessity as if your competitor has it then you will loose sales as the consumer is being mislead.

What do Shed Buyers think of ShedSafe?

They think it is a regulatory body equivalent to the BCA or Australian Standards. Wrong, wrong, wrong!!!!

Is Shedsafe going to protect consumers?

In its current state there is no way consumers will be protected.

Does Shedsafe ensure a 15 year product roof warranty?

No – not even its benefactor does a warranty on 0.35BMT roofing, which is being supplied by some Shedsafe accredited members.

Are Shedsafe accredited suppliers allowed to use 0.35BMT on their roofs?

This is the key to this whole business, some do and some don’t! Shedsafe does not provide even basic consistency in shed supply.

ShedSafe – An Industry Body or A Brand – Part 1?

Posted on : August 28, 2011

ShedSafe – an offshoot of the ASI and The Shed Group!

This is a look at the Industry Body called ShedSafe and will raise many eyebrows in the shed industry through the dominance of its name. The presumed importance of a brand called ShedSafe with its accreditation deeming members have an exclusive right to the name is confusing to the consumer in the assumption it is a regulatory body. It is not such a body as all shed (Class 10A Buildings) constructions are governed by the BCA only. This fact is mentioned in the ShedSafe advertising.  The advertising aspect is the point of this investigation and the implications that this “ShedSafe Group” imply not to the customers – but to its members and opposition – Non-members of compliance of shed construction!

Lets go through some of the ShedSafe details advertised to the customer and also to prospective shed suppliers.

Is your shed..ShedSafe? If not why not? This is marketing and nothing else – the problem is in the wording as follows by one of the accredited suppliers. It implies that it is the industry standard benchmark. Just to confirm all the major brand users of this ShedSafe have similar branding advertisements.

ShedSafe Accredited Supplier Advert

 So we have an Industry body who commercially sprouts its advantages through its members directly aimed at customers through the statement above “This accreditation is the Industry Benchmark for Steel Sheds sold nationwide”!  Why are they saying this when in reality they are not the benchmark but simply a brand as discovered below!

This is on the literature to shed suppliers – so make no mistake as to the marketing intentions of this statement! Join up and you will influence the purchasing decisions of most, if not all consumers shopping for sheds! This is an unbelievable statement from an Industry body to gain membership. Yet on the following piece of information you have option of deflecting opposition to shed quotation by referring to the “ShedSafe Website”

 Yet in reality this is what you will receive from becoming a ShedSafe member – the below:

 

Not much promised to the customer who buys a shed except that the shed you have purchased is ShedSafe accredited. See some previous articles here on Shedeye for ShedSafe accredited sheds…

Next is a very important statement by ShedSafe conditions to shed suppliers:

Now this is an important concept – as all factors quoted must be performed by a licenced builder or a building certifier. Also an engineer may perform this duty. But how many quotes get published to customers without any inspection or site visit?  This is an area that ShedSafe has yet to address!

NOW THE LAST PART OF THIS ARTICLE!

Stay tuned for Part 2, a much harder hitting continuation of this article.

Insulation and your new Shed?

Posted on : June 13, 2011

Like everything in the shed industry, insulation is another area full of jargon.  When you break it all down it is not too complex, the only thing you need to make sure is that you are being sold insulation for your shed that is adequate for your area and you are happy to take on the increase in your shed price.

Shedeye has done a comprehensive analysis, you can Download the PDF here!

If this is too much for you to digest with your morning coffee, then all you need to focus on is the R value.  Effectively the higher R value the more thermal resistance (keeps heat in or out) that your insulation offers.  This is important if you are considering adding an air-conditioner or heating to your shed or garage.  The BCA (Building Code of Australia) has worked out the requirements based on your location and altitude for both the roof and wall.

The R values of the same roof or wall vary between summer and winter – depending on which way the heat is travelling.  It is best to achieve minimum R value in both seasons for the walls and roof.

Follow these steps to work out your minimum R value and how to select an appropriate insulation.

Step 1 : Use the BCA zone classification to work out your zone

 

Step 2 : Work out the minimum R value for your roof and wall based on BCA minimum R values.

Wall

Step 3 : Select a material that satisfies you minimum R-value in both winter and summer

Carport Exempt Developments

Posted on : April 8, 2011

NSW SEPP – Exempt Developments for steel Carports

Don’t be overwhelmed by the complexity of this flow chart, if you follow it step by step it is relatively straight forward!

Please click on the image for a larger view.

Where to start on this monster!

What is a class 7a building?  It is effectively a carpark for over 3 cars, this naturally excludes non-rural classifications  due to the 20 meters squared limit for non exempt developments.  It is interesting that the definition of a carport suitable for exemption is defined at least 2 open sides with at least 1/3 of the perimeter open.

Shedeye is not sure why some of these rules have not been applied to the Garden Shed exempt development for example

  • Must be at least 1 meter from any registered easement, sewer main or water main.
  • The roof of the development must be located at least 500mm from each lot boundary
  • 20 meters squared limit for allotments of less than 300 meters squared, and 25 meters squared limit for allotments greater than 300 meters squared

Why does a Garden Shed not require these rules, however a Carport does?

All in all the SEPP is a massive improvement and goes a long way to helping to improve the inconsistencies between councils in Australia.

Reflecting on Reflectivity

Posted on : April 6, 2011

Shedeye has questioned the ambiguity of the SEPP definition of “low reflectivity” and is going to expand more on this.  This article will explain the standards and map them to each other.  For a complete discussion go to the Shedeye Investigator  article.

The current requirements of reflectivity standards of metal cladding as seen in BASIX, BCA and SEPP all seem too ambiguous for correct applications and on site judgement and analysis. As explained below, the variations of each of these regulatory bodies will be apparent especially in the Class 10a or domestic shed/ garage construction and manufacturing industry. What are solar absorptance, reflectivity, gloss levels, heat transfer calculations, R Values, BASIX Scale, BCA Scale, and visual acceptability? All these factors play a role in the decision of colour choice (or ZINCALUME ®) of your shed metal cladding and roofing.

The standard by each authority vary and will cause some problems within the industry along with questions for the Building Certifier during the approval process. These variations on the choice of colour may affect the outcome of approval depending on which code is followed and whether or not the local council regulations agree or disagree with these codes.

Why is there a contradiction among something on coloured steel cladding when each colour has its own Solar Absorption Index Value? The reason for this is simple – each building (Class 10a) should be inspected individually prior to this decision of colour being made, to evaluate the different aspects of the codes above and the influence each requirement has on the following:

  • Visual Suitability (impact on neighbours)
  • Environmental Considerations (energy saving)
  • Personal choice (What colour you want?)
  • Building use (aspects of comfort levels within the building)
  • Building position (in reference to location of other building and aspect of sunlight etc)
  • Local Council requirements (necessary for approval)

As this spreadsheet describes the colours taken from the BlueScope website and lists four factors that are currently used in the building industry. How these play a part in colour choice for metal cladding on these buildings requires an understanding of each of the columns above. There are as follow:

  • Column 1. This is simply the list of ColorBond Colours, ZINCALUME and Metallic Colours from BlueScope.
  • Column 2. The Solar Absorption is simply a numerical index that shows the amount of solar “radiation” that is absorbed by that particular colour. This is not to be confused with reflectivity and the two are not inversely proportional to each other.
  • Column 3. SEPP is the body of government in NSW that has legislated the requirements of colour to be used in Class 10a buildings. The requirement is based on reflectivity and although not exactly stipulated – it only accepts Medium or Dark colours (low reflectivity).
  • Column 4. BCA has its own version of classification of colours in this list and refers to Very Light (VL), Light (L) and Dark (D).
  • Column 5. BASIX is the New South Wales Building and Sustainability Index body with its own colour classification and is as follows: Light (L), Medium (M) and Dark (D).

 

BASIX Solar Absorptance Scale

The BASIX scale is based on the following and is linked directly to the value of solar absorption index.

This can be located at http://www.basix.nsw.gov.au/docs/ under Thermal Comfort Protocols.


The Building Code of Australia (BCA) Colour Classification.

BCA has classified roof colour also on the basis of their solar absorptance, and referred simply as light, very light and dark. Very light is below 0.425 solar absorptance, Light is below 0.550 solar absorptance and Dark is above 0.550.

 

SEPP Colour Acceptance Scale.

This is quite simply stated as must be “low reflective material”. Being low reflective can only be Dark on the BCA Scale or Medium and Dark on the BASIX Scale. For the purpose of this investigation – the BCA scale has been used as this code is generally utilised by all local councils and Building Certifiers. The problem is not the cut off area – but simply in the statement of “low reflective material”.

NSW SEPP takes over from local councils on 1st September 2011

Posted on : March 29, 2011

Compliant and exempt developments will be determined by the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008, for all local councils from the 1 September 2011. This means that the SEPP will override ALL local environmental plans and development control plans for exempt and complying developments.

This a great piece of legislation, as any move to create consistency at the state or federal level is a brilliant initiative in Shedeye’s view! The BCA has made great inroads into standardising Building Codes for best practice and now the SEPP has moved to consistent approach for in applying Exempt and Complying Development Codes across NSW.

Can the regular human navigate this code easily, if you have a few hours to invest and have nothing better to read, then yes it is quite clear, with a few ambiguities thrown in for good measure. Where the SEPP is not clear is on how it all ties together, especially in the shed and garage playground.

There are a few surprises thrown in, for example a shed (not a carport) for any other purpose than a cabana, garden shed or a gazebo cannot be classified as an exempt development.  If you think a single car garage can come in as an exempt development then you have another thing coming! If you have a 3 meters wide x 6 meters long shed that is being used as a class 10a building and is not in one of the above then you are not building an exempt development, even though your floor area is less than 20 meters squared.

We have some more articles to demystify the SEPP soon.

Garden shed exempt developments

Posted on :

NSW SEPP for Exempt Developments for steel Garden Sheds

Shedeye has attempted to simplify the legislation around exempt Garden shed developments, not sure if we have, by creating a hopefully easy to follow flow chart.

Please click on the image for a larger view.

 

There is still some ambiguity in some of the legislations, for example what does low reflectivity mean?  Logic dictates that it means that you can not use zincalume in a residential setting (the classic tin shed), however what about the lightest of the colorbond (TM) colours, Classic Cream (TM)*, it has the highest reflectivity (the lowest solar absorption) with a Building Code of Australia (BCA) rating of very light.  If this is not allowed, a good quarter of Australian sheds would be in breach!

When a Shed is not a Shed!

Posted on : February 26, 2011

It is very important to get the classification of your shed, garage or carport correct (Class 1a or Class 10a) as per the previous article.

Take the following Development Tribunal decision from the Toowoomba City Council as an example of getting the classification wrong.

In this case a carport was used as an entertainment pavilion, however the council gave approval as a Class 10a building in the expectation that the structure was to be used as a carport.  When the builder went to sell the property, the carport was completed and used in the promotions for the sale of the property, by the builder, as an entertainment pavilion. The applicants bought the property on the understanding that the structure could be used as an entertainment pavilion.

The new owner’s decided to put in a pool that would block vehicular access to the Class 10a structure.  The council came to the conclusion that “…when used as an entertainment pavilion it is considered habitable i.e used as part of living in the residence.”

This case became complex and eventually the ruling from the Tribunal was “in accordance with Section 4.2.34(2)(b) of the Integrated Planning Act 1997, changes the decision of the Toowoomba City Council, dated 6 September 2006, by allowing the structure to remain in it’s current location and re-classifies the existing structure from a Class 10a carport to a Class 1a building subject to the structure remaining 100% open at all times”

Who was responsible for paying the additional fees to convert the building from a Class 10a to a Class 1a?  Not to mention the amount of time that was invested from the new owners, in presenting their case to the Council and Tribunal and the delays it caused to adding their pool!

There are a great many cases where the classification has been made incorrectly and it has caused a great deal time delays, and in some cases cost.

Take a look at this article where a building was funded from the federal stimulus program for Black Rock Primary School, it was incorrectly classified as a Class 1oa and it looks like it will have to be moved.  Try moving a $200,000 shed!!

What a pain, make sure you classify you shed correctly!

Is your shed a Class 1 or Class 10a Building?

Posted on : February 25, 2011

Class 10a and Class 1 Buildings

According to the BCA (Building Code of Australia) a Class 10a building Is defined as a non-habitable building being a private garage, carport, shed, or the like.

While the BCA defines a Class 1 as one or more buildings, which in association constitute—

(a) Class 1a — a single dwelling being—
(i) a detached house; or
(ii) one of a group of two or more attached dwellings, each being a building, separated by a fireresisting
wall, including a row house, terrace house, town house or villa unit;
or
(b) Class 1b — a boarding house, guest house, hostel or the like—
(i) with a total area of all floors not exceeding 300 m2 measured over the enclosing walls of the
Class 1b building; and
(ii) in which not more than 12 persons would ordinarily be resident,

When we are talking sheds, it is almost always the distinction between a Class 10a and Class 1a that cause confusion as Class 1b is unlikely to be a shed!

This makes the classification quite a simple task and it is all in the definition of Habitable and Non-Habitable rooms.

Class 1a building

If you have a room in your shed (even if the shed contains only a single room) that contains any of

  • Bedroom
  • Living Room
  • Lounge Room
  • Music Room
  • Television Room
  • Kitchen
  • Dining Room
  • Sewing Room
  • Study
  • Playroom
  • Family Room
  • Sun Room

Then you have a Class 1a building.

Class 10a building

And if all of your rooms in your shed contain only

  • Bathroom
  • Laundry
  • Water closet
  • Pantry
  • Walk-in robe
  • Corridor
  • Hallway
  • Lobby
  • Photographic darkroom
  • Clothes-drying room

Then you have a Class 10a building.

The only tricky bit

The only ambiguity left in the BCA definition of Habitable and Non-Habitable is the statement that rooms or “Spaces that are not occupied frequently or for extended periods” are Non-Habitable.
So what are items like a Cinema or theatre room defined as?  The are defined a Habitable under this definition (take a look at this advisory notice from the SA Government).

Why is this even important?  From a paperwork and regulation perspective it is far easier for Class 10a buildings!

What would The Ten Humble Uses for a Shed be classified as?
