Project description:

Andy Mallard and David Cooke were engaged to provide capital cost estimates, cost planning, value management, cost in use studies, construction cost cash flows, risk management advice, contract documentation advice, procurement management, business plan input and financial reporting.

As Cost Manager, Andy Mallard was involved in the stadium project since its inception in 1995 following Wellington City Council decision to fund a regional facility rather than separate sport facilities.

Our approach

The client’s main objective was to create a world-class outdoor stadium to house major sporting activities (principally rugby union and cricket) as well as a venue for major entertainment events all within a limited budget. A priority was to ensure risk was managed at all levels and transferred where possible to contracting parties.

Two major areas of risk were identified very early on in the concept development; design responsibility and, as the stadium was to use neighbouring land as landing points for public egress, coordination with adjacent land owners.

The project management team, which Andy and David were an integral part of, decided after in-depth analysis of all the potential procurement methods, to adopt a variation of the design build process.

The concept was developed to a stage where a performance brief, along with sketch drawings and a cost plan, formed the basis of tendering for, and selecting, design/build contractors. Once engaged the chosen builder assumed responsibility for the delivery of the completed facility including all design work.

The ultimate procurement strategy necessitated complex contractor and designer agreements to ensure the transfer of risk, acceptance of design responsibility (via consultancy agreements, deeds of warranty, deeds of novation and service agreements), certainty of cost and the pre-determination of quality were clear and understood by all parties.
