I realise this is fairly common practice, but is there a rule-of-thumb in terms of where I can safely make service holes in the web of a 203.102.23KGx5600mm beam - similar to the Part A joist notching rules?
Ideally I'd like a set of three 30mm holes in the centre of the web, around 600mm from the end of the beam.
Is there a standard approach that a BCO will accept or would he need me to demonstrate that my SE has designed the holes in?
How far from the ends of the beam must they be?
How far apart from each other should they be?
Thanks
Gary
