Your Contractor Is Failing: A Worked Comparison of Fixing or Replacing

Replacing a contractor mid project feels decisive and costs more than owners expect. A worked example of the two routes with the numbers side by side.

A failing contractor presents two options: support and restructure the existing arrangement, or terminate and bring in a replacement. Termination is emotionally satisfying and commercially expensive, because a replacement prices the unknown, the site stands idle and your guarantees may not cover the gap. This example compares the routes on one project.

The situation

A building is 60 per cent complete against a SAR 18,000,000 contract. Progress has fallen to a crawl, subcontractors report late payment, and the contractor has asked for an advance against future work. The owner is deciding what to do.

Assumptions (illustrative)

• Contract sum: SAR 18,000,000, with SAR 11,200,000 certified and paid to date.
• Assessed value of work physically in place: SAR 10,400,000.
• Retention held: SAR 560,000. Performance bond: SAR 1,800,000.
• Estimated remaining work at original contract rates: SAR 7,600,000.
• Replacement contractors typically price completion of another build at a premium of 20 to 30 per cent over original rates.
• Owner cost of an idle site: SAR 150,000 per month in financing, fees and security.
• All amounts are illustrative assumptions used to compare the two routes.

Step 1: Establish the overpayment position

Paid SAR 11,200,000 against work in place of SAR 10,400,000 is SAR 800,000 paid ahead of the works, partly offset by retention of SAR 560,000.

Your net exposure before security is SAR 240,000, which tells you how much room you have to negotiate from strength.

Step 2: Price the replacement route

Remaining work of SAR 7,600,000 at a 25 per cent premium is SAR 9,500,000, an additional SAR 1,900,000 over the original rates.

A replacement contractor prices the risk of inheriting someone else work, and that premium is the main cost of termination.

Step 3: Add the idle period

Termination, tendering, mobilisation and survey of existing work realistically leaves the site idle for three months, at SAR 150,000 per month, which is SAR 450,000.

The gap is unavoidable, and it is the cost owners most consistently omit when they decide to terminate in a bad week.

Step 4: Total the replacement route

SAR 1,900,000 premium plus SAR 450,000 idle cost, less the SAR 1,800,000 bond if it is payable, gives a net additional cost of roughly SAR 550,000 before legal costs.

The bond is the variable that decides this arithmetic, and whether it pays out is a legal question rather than an assumption.

Step 5: Price the restructuring route

Paying subcontractors directly against assignment of their contracts, with payment moved to fortnightly certification and no further advance, might cost SAR 200,000 in administration and cash flow support.

Restructuring is usually far cheaper if the contractor problem is cash flow rather than competence or solvency.

Step 6: Identify the decisive question

Restructuring costs roughly SAR 200,000 and keeps the programme. Replacement costs roughly SAR 550,000 net plus three months, and only replacement solves a competence or solvency failure.

The decision is not about cost. It is about diagnosis: cash flow problems can be restructured, and insolvency or incompetence cannot.

What changes the answer

• If the bond is not payable on demand, the replacement route becomes far more expensive and slower.
• If the contractor enters insolvency, the choice disappears and preparation is the only thing that helps.
• If the remaining work is mostly finishes, the replacement premium tends to be lower than for structural work.
• If you have paid substantially ahead of the works, your negotiating position weakens in both routes.

What the numbers tell you

• Diagnose before deciding: cash flow, competence and solvency call for completely different responses.
• Never pay ahead of the work, because that gap is exactly what you lose in a failure.
• Check whether the bond is payable on demand before you rely on it in any arithmetic.
• Include the idle period in any termination decision, since it is a certainty rather than a risk.
