Price the terms you cannot change

Every clause that stays in the subcontract has a cost, paid in cash flow, in risk or in margin, so it belongs in your price. Put a figure on each one you could not get changed.

Why it matters

Terms are often treated as the lawyer's part of a subcontract and the price as the estimator's, and the two never meet. Yet a 60 day payment period ties up working capital every month. Retention held until the whole project completes costs a year or more of financing. Uncapped damages carry a risk your margin was never built to absorb. When the terms cannot be changed, the price is the only place left to deal with them.

How to do it

  1. Take the clauses you asked to change and could not, and the ones you chose not to raise.
  2. Put a financing cost on each payment and retention term: the sum held, for how long, at your cost of borrowing.
  3. Put a risk allowance on each liability term, from a realistic worst case on this programme and how likely it is.
  4. Keep the total as a line of its own in your price build-up, so it is not discounted away in negotiation.

Example

Illustrative example. The scenario and figures are invented.

The facts

A flooring subcontractor is about to sign a £270,000 subcontract. The main contractor will not shorten its 60 day payment period or release retention before the whole project completes. Nor will it lengthen a 5 day notice period for variations.

What happens

  1. The subcontractor works out the financing. Payment 30 days later than its quote assumed holds back about one month's value, £30,000, across the 9 month programme. At 9 per cent a year, that costs about £2,000.
  2. Retention of 3 per cent, £8,100, held for about 14 months after the flooring is finished, costs about £850.
  3. It sets a risk allowance of £2,500 for variations lost to the 5 day notice period.
  4. The £5,350 goes into the price build-up as a line of its own.

The cost of the terms

ItemAmount
Later payment, financing£2,000
Retention held to project completion, financing£850
Risk allowance, variation notice period£2,500
Added to the price£5,350

The outcome

The terms the main contractor would not change are paid for in the price. Otherwise they would have come out of a 6 per cent margin of £16,200, cutting it by about a third.
