Olympic Stadium
Construct 19 no holding down bolt boxes for test erection of the new flexible seating conversion to
a football stadium for West Ham Utd. Seating is also removable and re-configures for athletics. Stadium will be used for 2015 Rugby World Cup.
The contract was awarded on Thursday 13th March 2014, on Friday 14th work on site with 2 men. 12 boxes were ready and poured on Monday 17th and the last of the boxes was poured at 1pm on Tuesday 18th March. All shutters stripped and removed from site by 9.30am Wednesday 19th March. Huge savings in cost due to lower hire and reduced labour.
Brief
Fast-Form Systems Ltd were approached by Brett Noble MD of BDN Construction Ltd to supply a formwork system to construct 19 no bolt bases ranging in sizes from 1.3m x 1.3m x .9m deep to 3.9m x.1.9m x .9m deep, including hire of all ply (Wysaform MDO used) and materials required delivered to site in Newark in 2 days time.
The other systems considered were traditional timber shutters and well known panel system so we are able to show cost & time comparisons which are shown below.
Fast-Form provided the lowest quotation for the works and was also asked to install the system, this was then passed to one of our nominated who undertook the contract on a supply and fix basis. The boxes had to be finished by Wednesday 19th March at the latest for the steel contractor to start erecting the seating. All boxes had to be shuttered at once so no re-use of materials!

All shutters stripped and removed from site by 9.30am Wednesday 19th March. Huge savings in cost due to lower hire and reduced labour.
You will see from the photo’s that we have used timber rails to extend the centres of the brackets to reduce the number of brackets per base this was in part due to the short notice of the order which meant we were low on stock and also to show how less brackets can be used if you use a rail.
We also we tested smaller brackets strength by extending their height with 4 x 2 so a 600mm high bracket poured a 900mm high base proving the bracket can take much more than its own height in pressure. Normally ply would be applied directly to the brackets with no timber rails but at closer centres.
Alkus ply was used to demonstrate the strength of the new German ply with no rails at 600mm centres. Alkus will shortly be offered on a hire and sale basis.

| Speed of system |
Lightweight and fast to erect, no make-up required
|
Metal panels and rigid sizes mean oversizing some bases resulting in higher concrete costs or ply inserts resulting in more time to fit
|
Make up of shutters double duration of the contract, also timber needs stripping and de-nailing and needs to removed from site |
