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.
