Work category 322: Replacement of bridges and structures

Introduction

This work category A type of activity – not confined to a particular activity class, e.g. new roads (work category 323) appears in:

* activity class 12 – local road improvements
* activity class 13 – state highways improvements provides for the upgrade or replacement of existing bridges A structure designed to carry a road or path over an obstacle by spanning it. This includes culverts with a cross-sectional area greater than or equal to 3.4 square metres. and other road structures, where this is the main purpose of the work.

Examples of qualifying activities

Examples of qualifying activities include, but may not be limited to:

• replacing a structurally inadequate bridge
• replacing a bridge for non-structural reasons, such as inadequate width or waterway
• modifying an existing bridge to increase its structural capacity to a level higher than originally provided
• widening an existing bridge
• approach work estimated to cost less than $50,000
• for local road projects property purchase costs less than $50,000
• replacing retaining structures, including sea walls, that support a road
• replacing tunnels
• replacing culverts One or more adjacent pipes or enclosed channels running across and below road formation level having a cross-sectional area less than 3.4 square metres. having a cross-sectional area of 3.4 square metres or greater, and
• sealing bridge approaches on unsealed roads, where:
  • the approach sealing is limited to a maximum distance of 50 metres from each abutment An end support of a bridge or similar structure. , and
  • the seal continues over the entire structure to ensure consistency of skid resistance.

Other potential activities not shown above should be discussed with the Transport Agency for eligibility.

Funding approval Approval given by the NZTA under section 20 of the LTMA. is subject to conditions as set out below.

Exclusions

Exclusions include:

• the provision of a new bridge or other structure where no structure presently exists – these are funded under Work category 323: New roads.
• replacement of a cattle stop – this is funded under Work category 215: Structures component replacements, and
• maintenance of existing retaining structures should be conducted under Work category 114: Structures maintenance.

Conditions of funding approval

The conditions of funding for replacement of bridges A structure designed to carry a road or path over an obstacle by spanning it. This includes culverts with a cross-sectional area greater than or equal to 3.4 square metres. and structures include:

• the cost of proposed replacement must be checked against the Transport Agency’s policy on uneconomic roading facilities prior to an application being submitted through Transport Investment Online.
• new or replacement bridges A structure designed to carry a road or path over an obstacle by spanning it. This includes culverts with a cross-sectional area greater than or equal to 3.4 square metres. proposed for funding from the National Land Transport Fund must conform to the requirements of the Transport Agency’s Bridge Manual. The Transport Agency may approve a specific departure from these design standards in terms of its policy on uneconomic roading facilities.

Funding assistance rate (FAR The usual contribution in percentage terms, that the NZTA augments funding of an approved organisation, for the delivery of an activity or combination of activities. )

The usual funding assistance rate is:

• the Approved Organisation's normal FAR,
• the Approved Organisation's special purpose road improvements FAR; or
• 100% of the Transport Agency's state highway costs.

Applying for funding approval

Applications for funding approval of proposed projects should be made through the 'Improvement activity' module in Transport Investment Online (TIO The NZTA's web-based funding allocation system. ). To be eligible for NLTF The fund established under section 10 of the LTMA funding, any new activity must be added to the relevant Regional Land Transport Plan and to the NLTP A National Land Transport Programme Interrelated and complementary combination of activities that, when delivered in a coordinated manner, produce synergies – can span more than one work category and more than one activity class, e.g. a programme could include a road improvement and public transport improvement activities. adopted by the NZTA under section 19 of the LTMA, as from time to time amended or varied .

End of year carryover

Transport Investment Online (TIO The NZTA's web-based funding allocation system. ) will automatically carryover the unspent allocation every year.  Therefore it is vital that Approved Organisations and the Transport Agency (State Highways) declare the unused allocation for completed projects by making a cost scope adjustment via the Reviews module in TIO The NZTA's web-based funding allocation system. .
