The Warrell Creek to Nambucca Heads Pacific Highway Upgrade is a $600M D+C project that includes a 19.5km new dual carriageway road; new interchanges; and new bridges including an 800mm bridge over the Nambucca River. RBG was engaged by the Acciona-Ferrovial Joint Venture (Pacifico) for civil and structural temporary works design, including the design of an 8ha pre-cast facility.

The facility included design of earthworks and high-load pavements in backwater swamp conditions; access roads for light and over-sized vehicles; precast shed with girder forms and girder storage; and drainage systems with water quality management measures. RBG prepared multiple earthworks modelling scenarios to gain efficiencies in the earthworks for a complicated site with poor ground conditions. RBG undertook flood analysis to determine appropriate flood protection levels for the facility, as the site was located in an area prone to flooding. RBG also provided building design services for the casting shed using a specialist sub-consultant.
