RM调查，为商业，资源和住宅行业提供端到端调查解决方案的澳大利亚公司很高兴成为新的一部分Western Australian Museum建筑项目。这项395.9澳元的项目包括设计和建造与现有遗产建筑集成的新建筑物；遗产修复适用于老守高，禧年，博福特和哈克特建筑物；以及新西澳大利亚博物馆网站的公共艺术项目。

The dramatic new design links contemporary architecture with historic and heritage-listed buildings. The architects' main task was to merge the historic and heritage-listed buildings with the new state-of-the-art structures.

The task? Four, heritage buildings initially made from timber required structural steel to reinforce and enable improved exhibits. RM Surveys were tasked with the laser scanning component of the project, which includes the large halls featuring 6,000 square metres of galleries to stage large scale special exhibitions, learning studios, spaces to experience behind the scenes work of the Western Australian Museum.

Going where no other laser scanner has gone before

RM调查团队使用了一些Leica Geosystems解决方案来捕获，建模和分析数据。从Leica ScanStation P40调查级3D激光扫描仪，测量师在大型大厅中使用了扫描仪P40，因为它在大空间中的准确性很高。

The Western Australian Museum project was the first opportunity to integrate their newLeica BLK360imaging laser scanner into the project workflow.

The team captured the roof space and the timber beams for a fabricated steel substructure which would be prefabricated and installed to support the 100-year-old timber beams and roof structure.

For this portion of the project, the BLK360 was the only laser scanner for the job as no other product could match the portability and access the confined hazardous work environment. The team also needed to navigate using the equipment while wearing special PPE and fall arrest devices.

“This project allowed us to learn about the capabilities of the BLK360 in small spaces. It was the only option our team had to capture the confined spaces, with the challenge being to maintain safety, accuracy and scope,” said Matthew Dowell, RM Surveys Laser Scanning/GIS lead.

The other challenge aside from navigating the tight space was the difficulty to gain survey control in the roof. Being a heritage building meant that the team could not cut or make any roof penetrations.

团队通过使用狮子旋风点云的云到云登记。由于屋顶空间的限制性质，调查控制只能放置在访问权限和出口指向“爬行”空间。对于细长的屋顶空间，团队可以在远端拆除几个瓷砖，并从街道上射击控制。这是为了确保数据集的准确性（主要是方向），因为团队向下移动空间（云到云可以将方向逐渐消失）。

新的西澳大利亚博物馆于11月21日（星期六）向公众开放，并提供了新的建筑物和新名称：西澳博物馆Boola Bardip。该博物馆是由Multiplex和Hassell + Oma设计和建造的，最近入围了澳大利亚建筑成就奖。
