Economic-Cost Benefit Analysis for Road Construction in New Zealand

The Project background

The Project background

The New Zealand Government, Te K?wanatanga o Aotearoa (NZG),�considers constructing additional lanes on a two-lane single carriageway for a motorway network of 2,033 kilometres. The motorway links the North Island and South Island, and the project delivery consists of two stages. Stage �1 �will complete the South Island section (952 km), constructed between �2021 and 2024. Stage 2 will begin in 2024 and complete the �North �Island section�(1,081�km�Km)�by�2026.�Figure�1 illustrates�the route.

Figure 1: Map Showing Route of the Planned Motorway

Motorway construction is not the core business of the government, and NZG and a private company (PC) share the project service delivery. The PC will operate the Project under Build-Operate-Transfer (BOT) contracting strategy. Table 1 shows the PC service delivery, Table 2 depicts the private company service delivery durations, while Table 3 presents the NZG service delivery and durations.

The government purchased the land at the start of each stage of construction and part of NZG capital cost at the market price.

Assume that the land cost at stage 1and stage 2 is NZD 800 million�each.

1.1.2�Motorway construction at an efficiency�price

  1. Assume that the project efficiency labour shareas:
    1. 60% unskilled locallabour
    2. 50% skilled locallabour
    3. 100% foreignlabour
  1. Assume that the marginal project inputs from sales tax on local equipment and material are15%.

  2. Assume that the marginal project inputs for import duty on foreign material and equipment are5%.

  3. The opportunity cost of land is approximately 50% of the cost paid to the previous occupants of the land.
  1. The shadow priceof unskilled labour is 20% of the wage, and the shadow price of skilled labour (local and foreign) is 100% of theirwage.
  2. NZG does not levy tax (GST) on imports

1.2�Investment cost breakdown for toll plaza�construction

The concessionaire means of recouping its investment is by the benefits from the toll during the concession.

1.2.1�Toll Plaza Construction At market�price

The Project has two toll plazas one constructed in 2024 and the remaining in 2026. Each toll plaza costs NZD 75 million. The construction cost composition includes 30% imported materials, 40% local materials, 10% skilled labour, and 20% unskilled labour.

1.2.2�Toll Plaza Construction At market�price�

The shadow price of the two tolls are:

  1. Assume the same marginal project input for Imported material is5%
  2. Assume that the marginal project inputs from sales tax on local equipment and material are 15%
  3. Assume the same shadow price in 1.1.2, and number6

1.3�Motorway�and�Toll�Operation�and�Maintenance�and�Salvage cost�

1.3.1�Motorway�

  • Motorway operation and maintenance cost at marketprice

The�operation�and�maintenance�cost�of�the�motorway�is�NZD150�million�per�annum. The cost composition is the same as the composition of its capital construction at market�price.

1.3.1.2�Motorway operation and maintenance cost at efficiency�price

The operation and maintenance efficiency cost of the motorway is the same for its capital construction.

1.3.2�Toll

  • Toll operation and maintenance cost at marketprice

The toll requires regular maintenance and periodic rehabilitation that amounts to 5% of the cost of the toll construction. The operation of the toll begins from 2024 for the first toll and 2026 for the second toll.

1.3.2.2�Toll operation and maintenance cost at efficiency�price

The operation and maintenance efficiency cost of the toll plazas is the same for its capital construction.

1.3.3�Salvage�Value

  • Salvage value at marketprice

The motorway and toll plazas salvage value at market price is 50% of their initial cost at the end of the concession, accrued to NZG.

1.3.3.2�Salvage value at efficiency�price

The motorway and toll plazas salvage value at efficiency price is 50% of their initial cost at the end of the concession, accrued to NZG.

1.4�Benefits of the Motorway�Construction

  1. Time value saved by drivers andpassengers
  2. Toll revenue received by the concessionaire andNZG
