Approved Plans To Detailed Drawings
Posted 09 November 2015 - 05:39 PM
Once I've got approved plans, do I have to use an architect to do the detailed/working drawings? I don't think my architect was too keen when I originally told her I was looking to build in ICF, maybe because she has never worked with it at all.
I'm sure I read somewhere that there are different types of architects who can do the detailed plans from approved plans? So I'm just trying to prepare and get quotes.

"Architectural Technician" can't call themselves Architect but could do the drawings you need..
I'd look for someone that has used ICF before. Perhaps ask the ICF suppliers if they can recommend someone?
Might also be worth giving Building Control a call. Ask if they are aware of any houses in your area built using ICF and what drawings/calculations were required.

Your engineer should be providing details of any structural points and specify lintels, steels etc...in a similar manner to any other construction.
The details for openings are all very similar albeit different dimensions.
Your engineer should spec- wall thickness. For domestic above ground, 150mm. Lintel depth per opening and rebar to be placed. Any other reinforcing needed. Grade of concrete to be used, slump, strength etc.... The detail os each opening will be as per the product chosen.
We didn't use any construction drawings for the ICF, but have used them for other things unrelated e.g timber frame, setting out and soil pipes.
As I say, just remember that all it is is a poured concrete wall. Don't let anyone make it out to be more complex than it is.

Jamie, just reading what you wrote simplifies it completely and you are absolutely right. Some people are just scared of what they don't know though, where I would look at it as a way of gaining new knowledge.

For the widths, again, make sure these are in increments of the modules the OCF can be trimmed at - generally 25mm or 50mm (except for PW which you can cut to any width).
So as well as knowing your levels, make sure you know the lintel depths. Our engineer originally specced 400mm depth lintels with 2x16mm rebar and 200mm 'bearing' cast in - we only realise later that neither the engineer nor architect had taken this into account which caused issues with two openings where we couldn't get the 400mm - (although for those two he calculated 250mm would suffice). Again, same as masonry wall but good to know upfront.
I'll post pictures of our openings once we break out the timbers, which we will start doing soon.

A Chartered Architectural Technologist (MCIAT) is best explained on the Chartered Institute of Architectural Technologists web site - http://www.ciat.org....echnologist.cfm
An architectural technician is typically the office draftsperson / cad technician. They don't necessary have any training in construction or building technologies, they don't always carry insurance and aren't required to be registered with a controlling body. That said there can be plenty of knowledgeable ones out there that can provide a decent service, so compare what is being provided.
Never engage any construction consultant who isn't adequately insured for the work they are doing for you.
