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; 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.
