Summary of project

Riverstone Crossing is set in an idyllic location with varying terrain, a mountainous backdrop and tranquility of the riverfront in the northern part of the Gold Coast. Mortons Urban Solutions have been involved with the site since its inception providing due diligence and preliminary engineering advice. They were then commissioned to form part of the consultant team responsible for obtaining the relevant development approvals, engineering design and construction.

Development of the site is constrained by topographical and hydraulic considerations. Mortons Urban Solutions has been responsible for providing engineering solutions and a design which is sympathetic to these constraints, whilst maximising the developable footprint and balancing the environmental sustainability of the development. Mortons Urban Solutions’ input was instrumental in this project winning a Stormwater Industry Association award (2008 National Award for Excellence in Stormwater Harvesting and Reuse).

Mortons Urban Solutions’ ongoing role on this project is for the engineering of civil design, contract administration and inspection.


Status
