Subcontract claim defence on an MEP package dispute
A main contractor faced a USD 6.8M claim from a specialist MEP subcontractor over disputed programme, variations and back-charges. Ashforte built the defence position and negotiated a materially reduced settlement.
The situation
A specialist MEP subcontractor on a mixed-use development submitted a formal claim of USD 6.8M covering alleged programme disruption, unpaid variations, and disputed back-charges. The main contractor had rejected the claim in principle but had not built a defensible position.
The main contractor's internal team was capable but the subcontract administration through the project had been inconsistent. Back-to-back positioning between the main contract and the subcontract had never been formally verified.
The main contractor engaged Ashforte to build the defence position, verify subcontract exposure and lead the without-prejudice negotiation to settle the dispute without escalation.
Ashforte's intervention
The engagement was structured around the following workstreams, delivered by a senior-led team operating to Ashforte's standardized delivery protocols.
Subcontract audit
- Full subcontract clause-by-clause review
- Back-to-back position mapping against the main contract
- Time-bar analysis on the subcontractor's claim events
- Notice discipline audit — subcontractor's notice compliance
Defence positioning
- Point-by-point response to the claim
- Variation entitlement analysis — where the subcontractor had entitlement, where they didn't
- Back-charge substantiation for main contractor position
- Concurrent-cause and mitigation-of-loss argument
Negotiation
- Formal rebuttal issued
- Without-prejudice discussions across three sessions
- Package settlement framework covering all disputed items
- Escalation trigger to adjudication if settlement failed
The result
Settlement reached at approximately USD 1.9M — a 72% reduction from the original claim. Settlement included release of all disputed items and mutual withdrawal of any counter-positions.
Ongoing commercial relationship preserved. The MEP subcontractor was engaged on a subsequent project under revised subcontract terms.
The main contractor engaged Ashforte on a Portfolio Retainer with particular focus on subcontract administration discipline across their live projects — to prevent similar disputes emerging on other packages.
Lessons
The lessons from an engagement are usually more transferable than the specific results. What Ashforte's clients typically take away from case studies like this one:
Time-bar discipline on the subcontractor's notification cut the recoverable claim scope materially. This was contractual, not positional — the subcontractor had missed notification windows.
Undisciplined subcontract administration produces disputes that are recoverable but expensive to defend. Portfolio-wide subcontract discipline is materially cheaper than case-by-case defence.
Preserving the commercial relationship was worth accepting a settlement above the strict defensible position. Not every dispute goes to full defensive recovery — commercial judgment is part of the discipline.
This engagement sat within Contract Management.
Contract discipline across every live project — reviewed, tracked, defensible.
