Builder V structural engineer who is responsible?

[PSC88]

Hi

 

i have a main contractor and SE.

 

SE has provided a package for all my steel calcs and also the construction drawings for BC.

 

the builder is asking for working drawings for the build. The SE is stating some of these are out of the scope of his work and are the builders responsibility.

 

an example being we have bay windows….
 

the builder wants a full working drawings of the bay windows how to attached to the structure and the roof etc.

 

the SE has provided details of the load and lintels and specs and also Given a cross sectional view of the window with insulation details etc.

 

builder saying not detailed enough need info on how to build the dormer out and link roof to structure?

 

SE saying any builder worth there salt should be able to do this ? And the builder can use him for Clarification if unsure but it’s not his scope of work to go into such details ?

 

Are the both correct? Is one being more pedantic than the other i?

If you haven't paid for construction drawings you will not get them. It's more normal for the architect to do them, again you pay extra.

Your architect should have already produced GA’s (general arrangements) and some basin storey rods.

 

Your builder is right, no recipe book, no cake, otherwise the design onus is on him whereas it should be on your architect aka principal designer (it is they who will underwrite everything).

 

Have you tried saving money with architect fees? Prob the worst saving; subject to you having a good architect.
