解决具有挑战性的布局

Author:Tamara Stakic

这construction industry is embracing digital robotic total stations为了建立元素的布局和由于经过验证financial and time benefits– replacing the laborious tape measure and stringline approach.

传统上，现场建筑服务的布局涉及基于提供的纸张图纸的工作。这些图纸与胶带测量，水平和网格结合使用，以识别元素的位置点，例如穿透，管道和电缆托盘。这一切都在改变。

Digitising building construction layout

总部位于澳大利亚墨尔本，V结构专门研究高住宅和商业建设。他们最近的许多项目都采用复杂的设计，带有弯曲的墙壁和建筑物，并带有预制材料和非正交空间。寻求提高效率，确保准确性并提供质量控制，V结构购买了Leica iCON robotic total station后被任命为主要承包商Holme apartments development; a14-floor mixed-use developmentcomprising of continuously curved slabs, glazed curtain walls and balconies.

v构造，一个长期客户C.R. Kennedy, Leica Geosystems distributor in Australia, understood the need to adopt a digital workflow to work with complex shapes and move forward with the project faster than traditional methods. The company had little time to switch to a digital workflow after finding out it won the project.

“We needed a solution that was easy to adopt, user-friendly and required minimal onboarding time,”said Douglas Thirkell, senior surveyor at V Constructions.切换到数字工作流并采用乐器很容易thanks to C.R. Kennedy who provided technical support on site as the team implemented the iCON robotic total station from day one of the project.“产品是easy to pick up and use straight away by the team,”said Thirkell.

由屡获殊荣的约翰·沃德尔（John Wardle）建筑师（JWA）设计，雕刻设计包括154套公寓，地面上方的商业和零售空间，以及160-car parkwithin three basement levels. The building façade is a standout feature of the development with the original 1920s Art Deco façade being retained on the lower floor frontages and alongside a new suspended brickwork façade.

在图标机器人总站的帮助下，V结构为providing the accurate positioning of building structure, steel reinforcement, concrete layout and the finished levels。建筑物设计的复杂性质将使V构造团队几乎不可能使用传统方法布局。

切换到数字工作流程

V结构traditionally used Leica Geosystems total stations (Leica TCR407 and Leica Builder) for previous building construction projects. The complexity of the Holme apartments project made it necessary for the team toinvest in a layout instrument in order to be more efficient on the site。

Due to the complex nature of the building, each apartment is unique – there are42 different sizes of wet areasand not many repetitions of the apartments on each floor. This sophisticated structure involved a greater amount of work for V Constructions surveyors Thirkell and Brian McLoughlin as they had to layout each individual piece. The图标机器人总站允许团队以简单性和效率布局金属部分和制造的混凝土曲线。

“What was key for us when evaluating the technology investment is that the instrument had to be robotic and a one-person operation,”said Thirkell.

Tackling complex layout challenges with efficiently and accuracy

这team at V Constructions set up multiple survey control points on site for instrument orientation purposes at any location around the curved structure. This technique meant they did not need to use grids for orientation when completing layout tasks.

经过采用数字工作流程，V结构能够确保仪器的设置快速准确地完成andall plan data was immediately available on the controller。这确保了快速准确的布局过程were followed and there was no need to worry about some of the variables and the inaccuracies that come with using traditional methods involving stringlines, tape measures and spirt levels.

每个小错误都会导致潜在的严重后果。在一定程度上脱颖而出可能会导致预制的系统在安装它们时不适合。同样，错误的布局可能会导致与其他建筑要素或服务发生冲突，从而破坏施工时间表，产生不必要的作品以及浪费材料，时间和金钱。

On the Holme site, the windows of the building contained curves and the glaziers relied on the accuracy of the placement of the hobs to place windows – the hobs are premade and fixed to the form work. There was no room for error for the V Constructions team andonly a digital method could provide the team the confidence in accuracy needed– there was not a tape measure or stringline to be seen on the site.

“The traditional approach [to layout] is laborious and time-consuming, and any delays can affect the work of other teams.Adopting digitisation and the Leica iCON robotic total station is really the way of future for us，”said Thirkell.

加速计划

One of the key stages of the project that had tremendous efficiency gains was the as-built plans.

Thirkell and McLoughlin were required to complete an as-built survey for every slab. Traditionally, they would set up a laser level and take a reading, manually creating a plan of the completed slab in the office. With the iCON robotic total station,the team can record the data and within an hour upload it into CAD where it would be cleaned up and used to prepare the as-built plan。

量化生产率的提高，adopting an iCON robotic total station has saved V Constructions one person per day。这se are the considerabletime savings that may ultimately reduce the number of operatives requiredon the project and reduce labour costs.

Expanding productivity gains

V结构realised the productivity gained by implementing a digital workflow during the Holme project and invested in its second iCON robotic total station for a new project – a chancellery building at Monash University. Located at the Clayton campus, the10,000-square-metre building将包括一个用于停车场，地面公共空间，两个级别的办公空间和第三层的地下室级别，可以容纳大学高管。该建筑物包括一个功能钢制遮阳屏屏幕，该屏幕包裹着热增强立面的所有高程。
