Yes you are right about this type of work, but, some smaller housing associations are more interested in smaller companies. I work for 3, but, there is still all the stuff required that john said & more. i invested a lot of time & money in training, h&s & business development, so do not fear these contracts. Recently tendered for hospitals that was the biggest yet, you need more work to look good on paper when they assess you.
Price wise you,re right you would be looking about half what you suggest, i,ve tendered for one called beth johnson as trial i qouted 25p per window because i had info on prices already charged, i didnt get alook in at that price, so your looking at about a fifth of what some people qoute on here.
