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的内部装修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。现在都在改变。

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弯曲的墙壁和建筑物的复杂设计，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 stationafter being appointed as main contractors for the 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.“The product was easy to pick up and use straight away by the team,”said Thirkell.

由award-wi设计nning John Wardle Architects (JWA), the sculptured design includes 154 apartments, commercial and retail spaces above ground, and a160-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。这complex nature of the building design would have made it near impossible for the V Constructions team to layout using traditional methods.

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.

“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.

加快计划的计划

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 buildingwill comprise of a single basement level for car parking, ground level public spaces, two levels of office space and a third level to house the University executive. The building includes a feature steel sunshade screen that wraps all elevations of the thermally-enhanced façade.
