Project 2219 18mtr Covered Area GSG School Albany WA

Falling curved roof (free span 11.5mtr)

This project was finished recently, and this will help you understand the benefits of our system.

You will be able to see how quick the installation process is with our 74mm polycarbonate system, and how construction time is dramatically reduced. Installation time on this project was 3 days and four men were available on site. The supporting structure was already erected and in place.

Everbright E610 Opal was installed and covered a 18mtr area at the Great Southern Grammar School in Albany WA. Everbright E610 was extruded and supplied in complete 11.604mtr curved and 5.825mtr flat panels in 600mm configurations. Our panels simply clip together making the installation process rapid, as our product only requires to be joined every 600mm on site. E610 free spanned 11.5mtr, incorporating Locking System 2.5 on the curved area and free spanned 2.9mtr, incorporating Locking System 2.1 on the flat area (see design loads). The total area was 368sqm, the curved area was 11.604mtr x 21mtr with a 1068mm midpoint rise and flat area was 5.825mtr x 21mtr. Delivered to site were 70 panels.

The front fix method was used on the curved area, this is the preferred fixing method for larger span curved projects and is different from the top fix method. The front fix method provides more strength and stability. On this particular project the structure was set at a 13 and 30 degree angle to accommodate our panels.

E610 fixing accessories supplied as standard with large curved roofs;

a) Eaves angle EL16 supplied in 6mtr lengths and measures 40mm x 40mm x 4mm thick.

b) M8 x30 stainless steel bolts EL26.

c) E610 seals EL136.

d) Aluminium sleeves EL24 preassembled within the panels during the manufacturing process at 300mm centers.

The brief from our client for this project was for a product that was modern, could minimize structural requirements and had a long life span.

Our system was ideally suited for a project of this nature, due to E610’s free span capabilities, durability, and panel strength.

For developments of this nature E610’s additional benefit, is that in the unlikely event of students climbing on the roof or even falling from a big height, our polycarbonate system will not break or the joints separate. Making E610 one of the strongest translucent materials available in the world today.

Several other key factors were for a product that was rapid to construct, therefore keeping disturbance down to a minimum.

The Everbright E610 panels only needs to be joined every 600mm on site this makes the installations process very rapid.

Our 74mm polycarbonate system gives a unique visual appearance and modern uniformed look making use of all the natural light available.

All these factors made our system a excellent and obvious solution for this development.

Opal was the colour selected due to a 65 percent light transmission for visible light and a thermal performance of 1.85W/m"K.

Furthermore the client and project Architects we so delighted with the results on this project, that our 74mm polycarbonate system has been selected for a further two developments at the school where construction is scheduled for early 2010.

E610 LS2.5 Weight and dead load calculations;

Locking System LS2.5 = 14 kg/sqm with a dead load of 0.142kN/sqm.

E610 LS2.1 Weight and dead load calculations;

Locking System LS2.1 = 9 kg/sqm with a dead load of 0.091kN/sqm.

See design loads, which shows you in more detail the different locking systems available.

E610 polycarbonate panels incorporate as standard detailing an excellent safety factor. All loading criteria are based on 0.75kN/sqm and a 50% safety factor as part of a standard specification detailing.

Our polycarbonate system give a seamless and continuous line, with no steel frame work spoiling the visual effect. E610 Integral locking bars hide the aspect of where a panel starts and where it finishes, so it becomes a continuous system giving a uniformed and conformed design feature. Creating an architectural flare, that isn't possible with any other polycarbonate system available on the market. Other systems would necessitate the need for a framed grid work support system across the entire roof. On this project our system only needed to be secured to both sides of the eaves structure, all the joints are self sealing once the integral locking bar is fitted.

Our EL16 eaves angle is drilled on site at 200mm centers and is designed to fit our E610 panels. Once the eaves angle is secured, our panels drop in behind the eaves angle where the fixing bolts we supply are used to secure the roof to the angle.

Our 74mm polycarbonate panels are also fully trafficable, which makes a huge difference to construction time, and helps with general service and maintenance of the roof.

The construction process with E610 is very simple and is less time consuming to install on site. We can advise that there was a significant cost saving on the structure requirements with our system on this project.

Major Advantages:

Superior free span capabilities (see design loads)
Fully Trafficable.
Light weight product. Each panel could be easily lifted and locked into place on site.
E610 supplied in one complete flat or curved 12mtr length.
Less structure means less shadows created and as such the natural light translucency is at its full potential.
Great visual architectural effect.
Silicone free system. No possible leakage where product is sealed.
Translucent so that it maximizes natural light without excessive glaze.
Great thermal performance and sound reduction.
Self cleaning dome shape profile.

The geometry details on this project were:
Free span 11.5mtr / Internal radius 15.037mtr
Slopes 13 & 30 degrees
Midpoint height 1.068mtr
Curved length with eaves 11.604mtr
Length of drip nose eaves 90mm

This site is situated at the Great Southern Grammar School on Nanarup Road, Albany, WA and this project can be viewed should adequate notice be given.
