Atlas Copco’s intelligent and simple-to-use compaction system gives contractors real-time material stiffness readings to ensure superior soil and asphalt compaction. It maximises operator productivity, saving contractors significant time and money. Its touch screen capability makes the system user friendly and convenient.


Atlas Copco featured its [email protected] intelligent compaction system on the CC6200 asphalt roller at World of Asphalt in Nashville, Tennessee.


[email protected] uses a global navigation satellite system to track the number of completed passes and the precise position of the roller at all times. The unit’s drum-mounted accelerometer measures the surface’s relative material stiffness, and uses Evib readings to give operators immediate material stiffness results from within the cab and help minimise the number of passes.

 

When using [email protected] on asphalt the system uses two temperature sensors, one at each end of the roller, to register the surface temperature of the asphalt, giving operators consistent, relative stiffness readings. In addition, Atlas Copco’s intelligent compaction system helps contractors detect any loose materials so they can perform additional passes to reach the right compaction. This minimizes the risk of production related quality defects, which are time consuming and costly to remediate.


Contractors can use the intuitive system on a tablet to set project parameters and view compaction data. Once they achieve the optimal level of compaction, the program alerts the operator, so he or she can stop and reduce the risk of over compaction, which can affect the integrity of the material and damage the roller. The data storage also means contractors have

Will AR transform hospital construction?

The pandemic has focused minds on healthcare like never before with construction projects mushrooming globally.

The UK Government aims to build 48 new hospitals by 2030, committing £3.7 billion to projects so far, though a significant number are rebuilds. The full list is available here

Overall, the New Hospital Programme within the government’s long-term health infrastructure plan will help develop new sustainability standards, planning capabilities and care and workforce models. It will also implement "cutting-edge digital technologies" across the NHS, and will support an integrated approach to building new healthcare infrastructure using modern methods of construction. 

One of those technologies gathering momentum is Augmented Reality (AR), which projects virtual images into the user’s line of sight, and can be used on-site as a tool for creating the structure exactly as the design intended. 

According to a Research Dive report, the global AR in healthcare market is projected to generate revenue of $1,918.6 million by 2026, at a CAGR of 25.5% in the forecast period from 2019-2026.

London-based construction technology start-up XYZ Reality and UCL, were recently awarded a government grant, via UKRI and the Innovate UK Knowledge Transfer Partnership (KTP), to develop XYZ Reality’s AR solution. 

Founded in 2017, XYZ Reality developed Engineering-Grade AR to tackle some of the most pervasive and costly issues facing the construction industry. Its technology enables users to view hyperscale BIM models on-site in real-time and to millimetre accuracy, making it particularly beneficial for projects with complex MEP services, such as hospitals or data centres. 

Dr Grant Mills, Faculty Lead for Health and Associate Professor, said hospitals are complex construction environments because of the sheer range of MEP services involved. "This often leads to clashes and errors in the build phase, and the need for expensive and time-consuming re-work," he said.

Prof Duncan Wilson, Professor of Connected Environments in UCL Bartlett CASA, said the grant offers an important opportunity to understand how AR can help different users interact digitally with the environment in novel ways, and by doing so improve productivity, and deliver time and cost savings.

XYZ Reality’s founder and CEO David Mitchell said its Engineering-Grade AR technology is already being deployed on construction projects with the same levels of complexity as hospital builds, and is generating significant time and cost savings.

"I’m passionate about supporting the NHS, so I’m glad that this research will enable us to fully understand the benefits that our technology can offer these specific projects, and help those constructing UK hospitals to build it right, first time," he said. 

New technologies were key to delivering projects in double-quick time as the pandemic swept the world.

The North Lantau Hospital Hong Kong Infection Control Centre opened in late February following five months of construction. Using BIM, it produced 3D renditions of architectural projects, and shared layouts and other information with factories in mainland China, reducing on-site construction waste.

According to estimates by Goldman Sachs, AR and VR are expected to grow into a $95 billion market by 2025. 

But in terms of AR and new tech's benefits to healthcare, it's still early days. The King's Fund study published in April found "very little evidence of their impact on the health system to date, or benefits such as cost-effectiveness," though AR is being used for surgical planning and training.
