Table 4.

Key cost drivers

Project no.	Key cost drivers
1	Detailed design, mitigation and relocation of existing urban infrastructure, expenses due to polluted soil remediation and intricate traffic management during construction
2	Changing scope design and raising quality requirements
3	Raising quality requirements, extending the tram length, augmenting the number of stops and modifying the design requirements, mitigating and relocating existing urban infrastructure and increasing quantity of traffic arrangements during construction
4	Inclusion of an extra road junction (scope change) and the design development
5	Designs and technical solution development
6	Increase in design volume, raised quality requirements, increase in construction costs and client-initiated changes (in scope and quality)
7	Not publicly available
8	Design development, missing initial information from design, design changes, construction cost increases due to the COVID-19 pandemic and the Ukraine War and project delay
9	Not publicly available
10	Work efficiency innovations, effective risk management, systematic optimisation of project scope, the optimisation of soil material use, successful coordination of work phases with train operations and a flexible timetable
