Policy and Planning MWHProgramme, Indicative, and Detailed Business Cases for your infrastructure needs.

MWH, now part of Stantec, is a leader in preparing Business Cases for transportation clients within New Zealand. Our integration with Stantec further enhances our capability with vast international transport planning and design expertise.

We employ specialist consultants with expertise in all areas from programme business cases (PBC) through to indicative business cases (IBC) and detailed business cases (DBC).
Our local experience in this area has enabled us to streamline our services to ensure a robust strategic case is made, a wide range of alternatives and options are considered, and our reports are prepared in a clear and concise manner.

Recent Business Case Experience

Otaki to Levin PBC, IBC, DBC
Client: NZ Transport Agency
This study looked to determine a preferred alignment for an expressway between Otaki and Levin. The scoping report, however, indicated that an expressway was not appropriate based on demand. As a result, the programme of work now comprises a number of sub-projects which are being developed through the business case process. This has involved one Programme Business Case, one Indicative Business Case and two Detailed Business Cases.

In preparing these Business Cases, MWH undertakes robust option identification and selection processes. When selecting the recommended options, MWH balance safety, efficiency and local community objectives. As the projects
are in a sensitive area, the team integrate planning, environmental, cultural and social aspects with the optioneering and design from the start. On-going consultation with stakeholders, including Iwi, occurs throughout the business case process, and stakeholders provide valuable and meaningful input into the MCA.

Waitarere Beach Road Curves (Otaki to Levin) DBC
Client: NZ Transport Agency
This Otaki to Levin sub-project identified a preferred option to address the fatal and serious crashes at the curves on SH1 in the vicinity of Waitarere Beach Road, north of Levin. The project comprises a 2.5km road realignment through a culturally sensitive area.

MWH was responsible for the implementation of business case processes considering multiple alignments, geometrics, pavement, drainage, landscape, signage and delineation. Important planning, environmental, cultural and social aspects were integrated with design from the start, along with ongoing programmed consultation with stakeholders including Iwi. The resulting solution was considered ‘best for project’ and economically viable.

NgaurangaSH2 Ngauranga to Te Marua PBC
Client: NZ Transport Agency

MWH has undertaken the Strategic Case and almost completed the Programme Business Case for SH2 Ngauranga to Te Marua in Wellington. As part of this work we have identified and confirmed the major problems with strong and justified evidence in terms of efficiency, safety and resilience issues. We have undertaken option identification, option development, option sieving and programme development processes which are critical parts of the business case process. It also included facilitated workshops with key stakeholders who have praised MWH’s approach.

This robust application of processes can be applied to any Programme Business Case and is also useful at the Indicative
Business Case stage. This was part of NZ Transport Agency’s PBC Panel which included a ‘One Team’ approach with Agency staff in the regional offices, national office and planning and investment areas. As a result, MWH has developed and understanding of the needs and aspirations of different parts of the Agency.

DunedinSH1 Dunedin Separated Cycle Lanes DBC
Client: NZ Transport Agency
This initiative provides fully separated cycling facilities through central Dunedin SH1 between Queens Gardens and Pine Hill. MWH provided expertise around option investigation, stakeholder consultation, detailed business case production, scheme design, modelling, reporting, economic evaluation and cost estimation.

The project involved the reallocation of existing road space to uni-directional, fully separated cycling facilities midblock, along with various works at 25 signalled intersections and five unsignalled locations along the corridor. A
key requirement was to ensure the level of service was not diminished for vehicle traffic using the SH1 one-way system
which has been successfully achieved. There are few examples of complete DBC’s across New Zealand, and even less which specifically relate to a cycling project. MWH’s involvement in this project and the understanding we have
gained of the detail and approach required to achieve an approved DBC is unparalleled.

NelsonNelson Arterial Traffic Study
Client: Nelson City Council
The objective of the Nelson Arterial Traffic Study (ATS) was to determine the best transport system configuration to improve the city as a whole. It included an assessment of the existing arterial routes in meeting the needs of road users as well as adjacent communities. It progressively narrowed down an extensive list of options to four and assessed these in relation to transport impacts and other economic, social, environmental and cultural impacts, before making final recommendations. MWH led and undertook the vast majority of work related to this study. As part of the process, significant public and key stakeholder consultation was undertaken through facilitated workshops to bring the
community and decision makers along with the process.

Outputs from the studies included a four stage reporting process: evaluation of existing routes, selection of short
list options, evaluation of short list options, and determination of preferred configuration. This project outlines our ability to work through a robust, transparent and repeatable process for option development evaluation and selection as required for the Business Case approach.

Pyramid Bridge DBC
Client: Gore District Council
A strategic business case was completed by MWH in May 2014 documenting the case for changing access across the Mataura River near Riversdale. Pyramid Bridge is a single lane bridge built in 1930 on a low volume road with high local economic and socio-economic importance. The age and type of bridge means it is no longer fit for purpose and the continuing deterioration of the bridge increases the risk of failure. The local topography and historic location, however, means the bridge provides a key crossing for the area.

A number of defective structural components were identified on the bridge and a business case was required to determine an appropriate solution to address these issues. MWH proposed to Gore District Council, Southland District Council (joint owners) and the NZ Transport Agency that phase two could involve a combined Indicative Business Case (IBC) and Detailed Business Case (DBC). This is currently underway and is delivering cost savings with a streamlined process, while still allowing for an appropriate level of stakeholder engagement.
