# Structural Calculations - Single storey Timber Frame extension

I am looking for a freelancer who can assist me with structural calculations for adding a timber frame extension onto an existing brick residential building. I'd like someone with experience of providing calcs to clients in the UK.

It's a self-build single storey extension with slab foundation. Foundation is down and walls are up.

I’ve already worked with an architect who gave good advice and I got calcs for the slab foundation, which we thought would be all building control would want but now they are asking for calcs for the walls.

Their exact words are:

"We need the timber wall to have plans and calcs associated to it so that we know that wall will hold up to the loads etc.

We also need the engineer to plan and calc for the wall openings."

There is a sketch on there of the stud layout, its not done in proper CAD so I can’t easily add all dimensions but it is what I used for the wall build so it does accurately show everything that’s there including the size of the openings.

No stud is more than 400mm centres.

Walls are 47 x100

Roof is 47 x 150

Opening headers are 47 x 150

All C24 timber

Sheets are 9mm ply EN636-3 durability.

The roof weighs an estimated 1028KG, that is very light but mostly due to my planned use of lightweight steel roof tiles (Brtimet Slate 2000).

The planning application drawings are on there but I have made a slight change to window positions so please use those dimensions for the calcs.

I’ve also included the locations of the M12 chemical anchors (Rawlplug R-Kem II) used to affix the timber to the brickwork. These are shown in blue. The architect has since requested extra anchors in the form of Thunderbolts to be placed in the locations shown in red.

So I need the minimum in terms of drawings, just enough for the calc, I don't need materials takeoff, just the loading calculations.

There will also be future jobs from me including structural modifications of the existing house followed by a second extension, for both of which I’ll be needing further calculations in the next couple of years.

Thank you.
