Procurement Method Details
Direct award
Why this procedure was chosen
Under Schedule 5, a direct award is permissible where: • Only a particular supplier can supply the goods, services, or works required due to technical reasons, and • There are no reasonable alternatives or substitutes. For this case: • The odorant injection systems are proprietary to the Supplier, meaning the Supplier holds exclusive rights and technical know-how for these systems. • Integration with existing NJEX infrastructure and compatibility requirements eliminate the possibility of alternative suppliers without incurring disproportionate technical risk or operational disruption. • The scope includes commissioning and FAT by the Supplier, reinforcing that only Supplier can deliver the full requirement to specification. This aligns with the clause in Schedule 5 covering single supplier scenarios due to exclusive rights or technical constraints. Risks of incompatibility and operational failure if another supplier were engaged. The original procurement for initial equipment was competitively tendered for under UCR2016
