We’ve seen it literally dozens of times: clients with planning permission and a set of drawings from the architect and engineer. The same information goes to three builders and in return they receive a spread of prices:
£800k
£1.1m
£1.3m
So which builder is expensive?
The answer looks obvious and so many clients fall into the trap of being drawn towards the most attractive number here, but it isn’t that simple.
Before going out to tender, we always encourage clients to create the most complete and most thorough scope of work they reasonably can for their project.
It is tedious. It takes time. It requires effort and decisions.
But, as with most things, if you don’t put the effort in at the beginning, you shouldn’t expect great results. The more developed your scope is, the greater the chance of receiving accurate pricing and, just as importantly, comparable pricing.
It is very easy to think, “I don’t know anything about building, so I’ll let the builders work it out.”
The problem is that three builders working it out independently can produce three different interpretations of the same project. As the client, you are then left trying to establish exactly what each price includes – and what it leaves out.
We have seen clients get themselves in a total mess at tender stage because of exactly this. Three prices arrive, all based on different assumptions, exclusions and allowances, and suddenly nobody really knows which way to turn.
Underdeveloped scopes leave you open to receiving very attractive prices which simply do not tell you the whole story, and we have all heard the cliché ‘miles over budget’. Whenever I hear this, I can’t help but smile. So often it isn’t ‘over budget’, it was under-priced for one reason or another.
The level of detail required in a fully developed project scope can be surprising. We can ask dozens of questions about a generic scope of work, all of which affect cost and programme. Even the simple items. Face brickwork. How do you want the mortar joint finished? Or painting. Which manufacturer? What product? What finish?
Trust me when I say I could go on (and on, and on).
This is one of the main reasons we are such strong advocates of proper pre-construction and early contractor involvement. An experienced construction-led party can work alongside the client and design team before tender, asking these questions, identifying the gaps and helping develop the information into something the market can price properly.
At Taylor Kings, this forms an important part of our pre-construction service.
We help develop and refine the scope, coordinate the required information, obtain realistic pricing from specialist subcontractors and suppliers, and review those costs with the client and wider team before construction begins.
We have a tongue-in-cheek saying when discussing this with clients: “Do you want our price to win the job, or finish the job?”
