Pacific Motorway Package 1 was one of five major design packages for the 43Km eight lane
upgrade of the existing Pacific Highway between Logan, south of Brisbane, and Nerang near the Gold
Coast. Package 1 consisted of 4.8 km of eight lanes of motorway, service roads and three major
interchanges at Logan Motorway, Beenleigh North and Beenleigh South. A total of 16 bridge
structures where required for the works including a large span single cell post-tensioned box
girder and a variety of "super-T" and "deck unit" concrete bridges.
SAM was used for the deck analysis and design for various "super-T" and "deck unit" type
bridges on the Pacific Motorway Project.
The software was also used for section analysis of the post-tensioned box girder structure
which included ultimate limit state checks of the box section, differential temperature analysis,
analysis for section properties and torsion stiffness, design for local effects in the box girder
slab, and design of the substructure columns in bi-axial bending.
According to Maunsell McIntyre associate director Peter Kouparitsas: "While we used the Pacific
Motorway Project to cost justify our initial SAM license, the benefits have continued to be
realised on our subsequent projects including South East Transit Project, and the current Brisbane
Inner City Bypass."
