HS2 commissioned the DAM team to develop a tool that supported analysis of the whole Life Cycle Cost of HS2. The tool was used in comparing early design phase options for various asset types, including structures. The DAM team developed a scenario-builder that incorporated initial construction cost and future Operations and Maintenance (O&M) costs, such as inspection, maintenance and replacement of components.
Creating the tool required the team to utilise their engineering judgement and experience to produce indicative direct works costs. Consultation with the corresponding HS2 technical leads ensured that the correct interventions were being modelled to meet their needs.
