Mind the gap - curtain walling FFS

[Moonshine]

How stuffed is this situation?

 

We have a massive curtain walling system going at the front of our house, and right from the start the glazing company has been very clear the structural opening needs to be bob on vertical and the correct openings, we have been told that it needs a certain tolerance in the width and we were working to that

 

The agreed quote states this

 

Quote

Smarts MC600 curtain wall Anthracite grey/grey in Triple glazed 6/6/6 tuff Oversized handling/delivery Supply & install AGREED SIZES

 

With the agreed size provided in the quote as below, so i have been working to a structural opening of about 1820-1830mm x ~7530mm. My specification of windows provided for the quote stated outer frame dimensions, which are mirrored as per the quote agreed dimensions below

 

The frame has been fitted today, and i get home to find there is a massive gap down one side measuring about 30mm from the cavity closer (windows guys have left site)

 

I have measured the frame with a tape measure and the frame is 1770mm wide and 7480mm high.

 

Its like someone has taken the structural opening tolerances off the agreed frame size.

 

The company has the following in their quote T&C's

 

Quote

All frames are AGREED SIZES, therefore the responsibility of the client. 'the window company' will not take liability for any incorrect sizes.

New and altered apertures are to be the responsibility of others.

'the window company' will fit into prepared apertures which must be square, level and plumb

 

The glass for the curtain walling isn't on site yet, but either it fits this frame, or the glass is going to be too big for the frame fitted.

 

All the windows ordered through the company have all been the right size for the apertures.

 

he window company ordered the curtain walling frame so it seems that if they haven't provided the correct frame size as per the quote its on them, their supplier.

 

Tried to call the guy but his phone is off (suspicious), what the f&^k to do.

That’s crap - I expect they have applied tolerance at their end in the system. It’s why I always ask for the job sheet to approve with the actual sizes on it as their design systems can do this automatically.

The window fitter doing the order or their supplier?

 

All the window and bi-folds outer frames (different suppliers) which have turned up on site have been bang on the dimensions of the spec I provided and quote (no tolerance added).

 

If anything, i think that the curtain walling supplier has added the tolerances, especially as i have gone through loads with the window fitters what tolerances they needed for apertures.

I am tempted to text him to ask why the frame is 30mm thinner than the agreed size detailed in the quote.

I’ll tell you exactly what has happened, tolerance has been deducted from frame size. Simple as that to be honest.

 

Shit situation but did you receive and approve the final drawing sizes? They surely sent you them for approval? If you supplied them with specific information that the physical frame size was 1800mm and your structural opening would be 1820/1830. Then they have simply ****ed up.

 

Hopefully you’ll have this in writing regarding structural opening/frame size?

 

Don’t worry about glass, it will definitely be based on the supplied frame size 🤞🏻

 

You would be within your rights to request it be rectified or a solution found at their expense.

The image attached to my first post is the only dimension information i got from the window company. I didnt recieve any final design drawings for the curtain walling, i did for the bifold and windows and approved them (i was on these like a hawk and found a couple of errors)

 

Below is my window spec i provided to them via email (excel) for them to quote. W1 - W4 is the curtain wall (minus the door) which shows the outer frame diameter and opening widths

 

 

During the early stages of the build i emailed them that the as built strutural opening upto 2800mm above block and beam was around 1818mm - 1826mm.

 

Would the glass come from the same supplier as the curtain wall frame supplier? Next nightmare would be the glass being too big for the small frame.

If that's what you sent them, then the error is clearly at there side. Glass I would have expected to be delivered with the frame but it will likely be a separate glass supplier delivered to manufacturer or direct to site.

You say nightmare but wouldn't that be a good thing? They could manufacture a new frame that properly fits your opening and the glass wouldn't go to waste.
