Quoting for large decking job?

[Frimley111R]

One of our contractors has been asked about a 400 square meter decking job and although the materials are relatively easy to work out they have no idea how long it will take them, to the point that they'd prefer not to quote and leave them with a big job and no profit. They said that based on their last decking job the cost would be over £100K!! (Obviously not realistic). This is out of my area so to speak so thought someone on here may be able to help?

Well they can do it but this is the biggest one they've been asked about. Everyone has to start somewhere.

Can you compare to a smaller job you have done and multiply up into this one, at least as a reference point?

They did but that came in at over £100K. I guess there are economies of scale to be had!
