Draft Docs\6.1 Reports\Final\Inner City Routes Report Final.docx 13-Nov-2017 Prepared for – Wellington City Council – ABN: N/A AECOM Scenario Costing 1 Let's Get Welly Moving 1.0 Introduction 1.1 Purpose of this report AECOM is currently assisting Let’s Get Wellington Moving (LGWM) who are investigating a number of scenarios and interventions for improving the transport and urban planning outcomes for Wellington City. AECOM has been tasked with providing high level costing information for interventions (projects) associated with the different scenarios that LGWM is investigating. As well as providing rough order costs for the interventions and scenarios, this report sets out the high level assumptions and constraints identified to date which have been used to inform the cost estimates. Detailed design for the large interventions has not been undertaken and there will be a range of possible options for most of the interventions. This report bases the cost estimation at this stage on one of the possible options for each intervention. 1.1.1 Structure The structure of this report is as follows: Section 2 – Interventions Associated with Scenarios Section 3 – Assumptions about interventions; Section 3 – Constructability effects and constraints; Section 4 – Estimates. 2.0 Interventions Associated With Scenarios 2.1 Scenarios The following scenarios have been identified by LGWM: Scenario A – minimal infrastructure investment in conjunction with network priority and management changes, with the focus on improvements to public transport (PT) and active mode performance without significant road infrastructure investment; Scenario B - moderate infrastructure investment in conjunction with network priority and management changes, with the focus on maximising PT performance and conditions for active modes, while improving state highway 1 (SH1) resilience and reducing conflict between SH1 traffic and other modes; Scenario C – moderate to high infrastructure investment in conjunction with network priority and management changes, with the focus on improving PT performance and conditions for active modes, while improving urban amenity, SH1 resilience and reducing conflict between SH1 traffic and other modes; Scenario D - maximum infrastructure investment in conjunction with network priority and management changes, with the focus on improving PT performance and conditions for active modes, while delivering major improvements to urban amenity, SH1 resilience reducing conflict between SH1 traffic and other modes.
