The Royal Motor Yacht Club of NSW was a complex project undertaken in a live environment with expert precision. The temporary measures implemented by the builder to minimise disruption and optimise user experience were well received by the club. Real-time change management considered buildability and durability to achieve the architectural design intent within budget and program control. The high-end finishes achieved are exemplary, with European oak, aged brass and leather featured extensively throughout.  Due to the steep terrain on the site it was important that the existing members’ corridor alignment was maintained. Incorporated into the site establishment plan was an access corridor supported by formwork above the steep terrain. The scaffolding had to bear on rock and the existing staircase. The club provided a function schedule at the date of the contract but additional functions were booked during the construction period. Accommodating numerous functions per week required all works to cease and often with little notice, the flow of trades on site was disjointed, and organising trade availability was constantly changing. The builder was able to maintain this access despite the delay for up to three or four functions per week. Issues were met with existing multiple floor level changes and limited documentation considering compliance requirements. Procurement of specified products from overseas required direct contact by the builder to achieve the programmed delivery and installation dates. Also included in the contract was concrete cancer repairs. Years of harsh harbour elements had allowed concrete cancer to flourish.
