When you receive a scope of works or bill of quantities from a surveyor, she has told you in no uncertain circumstances that you are a commodity. Put your prices down for each item, you’ll be measured like for like against your competition and the cheapest wins. Your price is simply the only element in this exchange which is used to differentiate you.
There is no amount of marketing or clever tactics that changes this. If you don’t want to be a commodity, don’t price for work that comes with a bill of quantities.
