This picture shows a bird's eye view of the main pool.  The small concrete circles in the middle of the squares are the tops of the structural piles.  The 2 slightly smaller squares are part of the filtration system that will help keep the pool water fresh and clean.

The steel beams in the front of the picture span over the main pool and are approximately 16m long.  The roof over this area will be constructed from structural timber 75mm thick.  A combination of cell beams (beams with holes in) and timber were mainly chosen for their aesthetic appearance (we hope the people who are looking up at the ceiling whilst swimming back-stroke will appreciate the work involved!)  but they will also be extremely strong and durable.

This is another picture of the steel over the main pool.  The "Y" shaped columns were originally designed to be manufactured in one piece.  However, after a pre-delivery survey and a chat with the local traffic police, a decision was taken to manufacture these in 3 parts and bolt them together on site.  As I'm sure you are aware, the roads around York can be quite narrow and very busy.  We didn't think our neighbours would appreciate the traffic jam that we would have caused!

Here is the roof over the changing village and the steel work along the side of the existing sports centre.  Due to extensive planning and coordination with the sports centre staff, there will be minimal disturbance to the existing facilities.  In the bottom right hand side of the picture, you can see where the outer skin of cladding was removed to enable the initial tie-in of the structures.

Here is the foundation for the entrance canopy.  You can see the "ground workers" in the top of the picture laying the pipes.  These are to carry away the rainwater that lands on the top of canopy.  The wooden boxes are the form work (like moulds) that concrete will be poured in to.  These will form the plinths that the steel columns will fit on.  Each of the six columns is bolted to the ground with 8 no steel bolts.  These bolts will be placed to an accuracy of +/- 2mm horizontally and +/- 4mm vertically.
