The National Transport Authority (NTA) is seeking to enter into a single supplier work agreement for the supply of single-deck (shorter lengths) electric buses. While the NTA intends to acquire single-deck electric buses from the successful tenderer who is awarded the work Agreement, it intends to provide those buses to the operators of subvented public transport services, known as Public Service Obligation services, to operate in the performance of those services. Those operators include Dublin Bus, Bus Eireann, Go-Ahead Ireland and City Direct. As part of the provision of buses to the NTA, the Supplier will be required to enter into collateral agreements with the nominated operator in relation to vehicle warranties and other matters.
