The Bridge manual sets out the criteria for the design and evaluation of bridges, culverts, stock underpasses and subways and the design of earthworks and retaining structures. The manual has been developed by the NZ Transport Agency for use on state highways or for the design of other new or replacement bridges proposed for funding from the National Land Transport Fund (NLTF). Use of the manual on other highways, including private highways, may be considered appropriate with the agreement of the relevant road controlling authority, client or landowner.

Specification and guidance notes for pipe culverts including the construction of trenches, supply and placement of bedding, supply and laying of pipes, jointing of the pipes, construction of headwalls, wing-walls, aprons, drops, and intakes and outlet structures, the construction of connecting and outlet drains, as well as backfill of trenches and reinstatement. Consideration should be given in specifying in the specific contract documents the pipe installation in accordance with a relevant standard that will result in improved methods for construction, for example, NZS 4406: 1984.

This report presents a summary of the outcomes of a follow-on project to a research project commissioned by the NZ Transport Agency that culminated in the publication of research report 553 The development of design guidance for bridges in New Zealand for liquefaction and lateral spreading effects.
This project has involved summarising the pseudo-static approach developed in the research project for the analysis of bridge foundations on sites prone to liquefaction and presents two examples of the evaluation of the liquefaction hazard and two examples of the analysis of piled bridges on sites prone to liquefaction. This report is intended for engineers who are familiar with geotechnical and structural design practice for static and seismic loading of bridges.
