Onerous clauses don't get renegotiated post-signature
Time-bar clauses that operate as absolute waivers. Fitness-for-purpose obligations that override professional-standard care. Consequential loss carve-outs that swallow the exclusion. LD regimes with no cap. Warranty periods that outlast the contractor's insurance. Every one of these is negotiable before signature and effectively immovable after. Identifying them at bid stage is where the value is.
