Luton Outlaws - Independent Message Board for Luton Town FC

From an estimating perspective design and build is often more expensive. There is no design and so contractors do a design but add lots of financial fat as the onus is always on them and they have to include costs for things they may not have thought of.

Best practice is to offer a fully designed job (generally to stage 4) and then you will get both consistency of pricing, and everything will be picked up, or clarified.

Problem with designing to stage 4 is that the client has to pay for it. It's not cheap but in my opinion it's the best option.

Problem with D&B is that you can get all manor of shite.
