Installation of Balustrades





Each of the balustrades were cut to fit between the outer and inner beam, on site. The two beam faces had already been made as near vertical as possible when we cut and fitted the noggins. All we had to do was scribe the inner-beam face onto the toe of each noggin and cut off the surplus. Not as easy as it sounds as it always take two or more attempts to get it right.



The balustrades were each set with a lean towards the end of the bridge - at multiples of 5 degrees. So the middle balustrade was anchored at 90 degrees with the furthermost balustrade ending up at 125 degrees.



The heel and toe of the balustrade was then painted with bitumen by Alastair, as done on the noggins to minimise water penetration.



The balustrades were secured with stainless steel threaded rod from the outside beam through the foot of the balustrade and out through the other side of the inner beam. We also used stainless steel coach bolts to secure through the outer beam and into the leg of the balustrade. This gives a very strong hold.

The excellent team was ably assisted and inspired by Alastair & Tim Fison and Robin Le Mare.
