Karma Rottnest Lodge Rottnest Island

PROJECT: Karma Rottnest Lodge Development | Rottnest Island, Western Australia

CLIENT: Place Development

THE SITE

Karma Rottnest Lodge is a resort facility offering heritage style accommodation, located on the picturesque Rottnest Island. The A-Class nature reserve is situated 19km offshore from the city of Perth in Western Australia. The island boasts pristine beaches and coastline and is home to the Quokka, a small wallaby-like marsupial.

THE CHALLENGE

As a fully operational luxury hotel comprising of six individual buildings spread across 1.7ha with over 100 guests and 50 staff, creating a detailed 3D model with minimal disruption was a major challenge. To support a major upgrade to the hotel grounds and facilities the 3D model was required to cover internal rooms as well as the surrounding areas including courtyards, pathways and roads.

Sensitivity relating to guests’ rooms, wellness facilities and dining rooms were paramount in the project requirements. In addition to this the operational areas of the hotel from the kitchens, to reception had staff working throughout the day. Minimising the impact on their day was also a major consideration for the project.

The hotel is set amongst significant trees which were to be included within the model to ensure they were preserved, to be incorporated and featured within the upgraded complex. Furthermore, the hotel is located within an A-Class nature reserve with significant aboriginal heritage, and its impact on the surrounding environment was to be minimised at all times.

THE SOLUTION

Bearing in mind the project requirements and constraints a unique solution was required to execute the project and deliver a high accuracy 3D model. The key to success for the project was rapid data capture to minimise time spent in the hotel, both inside and the surrounding area.

MNG utilised their mobile mapping systems including the HALO-11 for indoor capture in conjunction with a terrestrial laser scanner for the surrounding grounds and to connect the model to the surrounding survey network.

Mapping throughout the internal rooms of the hotel was achieved using Simultaneous Localisation and Mapping (SLAM) technology to minimise intrusion through the hotel.

Additionally, a mobile 360° spherical camera was used to record high-resolution panoramic imagery throughout the courtyards, pathways and roads. This was a major benefit as it enabled other consultants to virtually visit the hotel without travelling to Rottnest Island.

The internal and external data sets were combined to create a highly accurate 3D model of the hotel.

THE OUTCOME

One homogenous 3D model was created for all buildings throughout the hotel to a level of detail that has allowed the architectural design to be undertaken for the project. A critical aspect of the 3D model is that all internal rooms were mapped to a level of accuracy to minimise any repeat visits to the site to gather additional data that was not foreseen at the outset of the project.

In addition to this, the 3D model enabled the landscape architects to develop their models for the hotel grounds. All trees could be accurately mapped for canopy and trunk sizes, along with limestone walls that are featured throughout the hotel. The panoramic imagery proved to be highly beneficial in this respect.

Finally, the survey was completed with a near-zero impact on the hotel guests which was one of the key criteria for the project.
