Westlink M7
The M7 Motorway was privately funded through an innovative construction contract method known as a "deed" to facilitate the expedition of the tendering phase; several deeds were drawn up based on the contractors proposals. The deed was for the full design, construction, operation and maintenance of the motorway including more than 40 kilometres (25 mi) of continuously reinforced concrete (CRCP) and asphalt roads, upgrading of local roads, the longest free-flowing (no toll booths) toll road in the world at the time. More than 90 bridges (of four different types) and the largest shared path network in the southern hemisphere. The design, construct, operate and maintain contract worth at least A$2.0 billion was awarded to WSO (Western Sydney Orbital Pty Ltd) by the Roads & Traffic Authority. The design and construct portion of the contract valued at A$1.8 billion was awarded to a joint venture between Abigroup and Leighton Contractors (ALJV) with design work undertaken by a further joint venture by Maunsell AECOM and SMEC (Snowy Mountains Engineering Corporation) with further subcontracting to other designers (Arup) and independent verification by Sinclair Knight Merz (SKM).
