What's the actual span - 2400mm?

What's the floor load?

A Intel 2.7m lintel spanning a 2.4m opening is good for 22kn

It is supporting floor joists but the problem part may be through blockeork that is also supporting roof trusses I am told so may need to be heavy duty but builder says no so will be getting the loads worked out properly before paying my balance
