Sigma offers a high level of expertise in all aspects of roading, including rehabilitation, reconstruction and associated services such as safety and technical auditing, peer review and strategic studies. Services cover preliminary feasibility reporting through scheme assessment/design to overseeing construction.

Roading projects range from small car parks for commercial and recreational sites, to specialist heavy duty pavements, local authority rural and urban roading, intersection and roundabout design, culverts and major bridges, and significant State Highway realignments.

Compliance with the Resource Management Act is mandatory for many of our projects. Reports and consent applications are prepared by Sigma, using specialist advice where necessary.
