JCT Mini-Series: Dangerous Amendments - Ten Common Amendments That Threaten Your Profitability

from The Subcontractors Blueprint · host Jacob Austin

In episode 133 of The Subcontractors Blueprint podcast, host Jacob Austin continues his mini-series on JCT subcontracts. He details the ten most dangerous amendments main contractors often add to JCT subcontracts, explaining their risks and how subcontractors can protect themselves. Jacob stresses the importance of reviewing and negotiating contract terms before starting work to avoid severe financial pitfalls. The episode aims to educate subcontractors on managing contractual risks, ensuring profitability, and safeguarding their businesses by understanding and challenging unfavourable amendments.  KEY TAKEAWAYS: Main contractors often amend JCT subcontracts, stripping out standard protections and shifting significant risk onto subcontractors. The episode highlights the ten most dangerous amendments, including pay when paid clauses, extended payment periods, and removal of suspension rights. Other key risks include shortened claim notice periods, main contract liquidated damages passing down, and linking practical completion and retention to the main contract. Amendments can also delete relevant events for extensions of time and transfer unforeseen ground risk entirely to the subcontractor. Subcontractors are urged to always compare amendments against the unamended standard form before signing and to negotiate or price in any added risk. Starting work without reviewing and challenging amendments can mean you are legally bound by highly unfavourable terms. BEST MOMENTS: "What's left looks like JCT on the cover, and it reads like something completely different in the clauses that matter." "If you start on site before you've read and understand every amendment to that subcontract, you may be deemed to have accepted those terms by your conduct." Some lists of amendments are as long as the subcontract started itself and effectively completely rewrite it in a no clause left untouched fashion." "If your subcontract starts tying your payment in any way to an upstream event, then get it reviewed." "Every invoice you raise becomes exposed to deductions that have no defined ceiling." "Your delay, real or alleged, becomes exposure to a liability calculated by reference to a contract that you've probably never seen against a completion date you've got no hand in setting."
