Stacker is an innovative mobile app that will extend construction workers reality with ‘intelligent’ Building Information Modelling (BIM) data. With Stacker, Exergy aims to foster a reduction in construction installation errors, time and waste whilst making useful immersive content available.
Our tool is specially designed to respond to the needs of the prefabricated construction industry (also known as off-site) in order to improve the efficiency of construction processes throughout the value chain.
Stacker will provide access to animated installation sequence that can be viewed directly through Augmented Reality (AR) via a smartphone application.
It will also facilitate the access to streams of communication between manufacturers, constructors and sub-contractors with built-in functionalities.
Stacker’s users will be able to:
Stacker mobile app will extend users reality with ‘intelligent’ Building Information Modelling (BIM) data, making useful immersive content available. We aim to reduce construction installation errors, time and resource waste.
With Stacker construction workers will be able to collect, store and display work package tasks and deliverables information and also track work package installation progress.
Users can visualise animated sequence of products in AR via mobile phones. Users have access to BIM data in a user- friendly and intuitive manner and capture on-site progress via photos and videos to reduce construction rework.
Digital installation will become accessible through: i) AR-enabled
BIM objects ; ii) ‘Pinformation’ using existing camera functionality to identify installation information in AR; iii) camera as a browser using computer vision.
With Stacker, constructors can simply click and drag for step-by-step visualisation and use ‘camera as a browser’ assisted AR on their smartphones.
There is clearly untapped potential in the use of immersive technologies to improve the installation of pre-fabricated products and eliminate incessant waste of building materials, resources and time due to un-skilled workers and misinstalled products.
The majority of the workforce will gain access to a valuable yet affordable product and eliminate the need for expensive high spec. desktop computers or high processing powers required from tablets.
‘Getting it right the first time’ with Stacker will mean an opportunity to benefit from cost reductions in housing, an improvement of quality within the construction industry and a contribution towards a better environment for current and future generations.
Stacker will not only benefit off-site constructors in the better management of construction projects in terms of the project management triangle: time, cost and quality. Instead, it will also serve our greater mission in the reduction of resource and construction waste. In the UK, poor design and management leads to approximately 13% (approx. 10 million tonnes) of wasted construction materials which frequently end-up in landfills for which the construction industry is also seen as the largest generator of industrial waste.
The offsite construction industry, together with digitalisation, is considered the future of construction. The Construction Leadership Council identified the use of artificial intelligence, digital techniques and off-site manufacturing as key strategies to deliver the government’s Construction Sector Deal.
iConkrete, our Spanish off-site construction partner will put Stacker to the test
We are using current state-of-art Android AR API development and computer vision toolkits. Digital installation manuals will become accessible for operators through:
We already have a prototype! Stacker capabilities include:
Our next step is enhancing these capabilities with a software neutral Industry Foundation Classes (IFC) sequencer.
We have presented our prototype among potential customers who are already perceiving the value of Stacker. The beta version presented to over 40 stakeholders has seen expressions of interest.
In November 2019, Stacker will be demonstrated among 50 participants in collaboration with Coventry University and showcased at the Digital Construction Week in London.
