The following four images show the internals of the bulkheads that run around the outside of the building. Their purpose is to provide large external gutters with a structure and to encase associated spouting.
 |
| The bulheads are made up of a series of 600mm x 660mm ply boxes set roughly 900mm apart. This photo is looking up from below the structure and the H3.2 treated boards that create the base of the soon to be laid guttering can be seen |
 |
| When the boxes have been bolted on to the internal framing of the building (we frame specifically for these boxes inside the building line) we wrap the boxes in weather proof paper and then overlay 7.5mm Hardiboard. |
 |
| This shows the boards laid across the top of the bulhead on which the guttering (coloursteel profile) is to be laid) |
 |
| Cavity battens set to take linear board over the top. |
