DokaXact interactive formwork positioning solution wins innovation award
By Jenny LescohierApril 14, 2021
DokaXact, an interactive sensor-based solution for accurately positioning wall formwork for vertical structures, has won an Innovation Award of Excellence from the Council on Tall Buildings and Urban Habitat (CTBUH).
CTBUH is a leading resource for professionals focused on the inception, design, construction, and operation of tall buildings and future cities. The annual CTBUH Tall + Urban Innovation Conference looks at the world’s best innovations in tall buildings, urban spaces, building technology and construction methods and rewards them with awards in over 20 categories. Doka will now compete for the Overall Category Winner at the CTBUH 2021 Conference in May.
DokaXact is a tool for surveyors and crews that allows site teams to quickly and precisely plumb and align wall formwork used with Doka climbing systems. The system was used first on Elephant Park in London and brought significant benefits, according to Wojciech Jawor, surveyor, AJ Morrisroe & Sons Ltd.
“The DokaXact system supported me ideally in my daily work as a surveyor. I did not need to be present for aligning and plumbing the formwork elements,” Jawor said. “However, I was able to monitor the site progress from anywhere at any time. This gave me more time and flexibility for other surveying processes on-site.”
The expectations on the precision of built in-situ concrete structures continue to rise. DokaXact supports this with its high system accuracy of ± 2mm. The system consists of multiple sensors attached to defined surveying points of the wall formwork, which communicate wirelessly with a centralized processing unit.
DokaXact assists and speeds up the surveying process before pouring. The site crew can align the formwork prior to the final position check by app assistance with predefined routines. This reduces the amount of re-measurements by the surveyor and possible formwork adjustments that would be required. The overall forming time will be accelerated
DokaXact provides a quality assurance tool to build more accurately. With the live monitoring function, potential movements of the formwork can be made visible at all phases - from the positioning to the pouring process. Site managers are now able to observe their building tolerances 24/7 from anywhere, allowing preventive actions to be taken in order to avoid cost intensive reworks after pouring.
On the DokaXact web portal, data are made accessible for site managers and surveying engineers. The portal is the reporting, monitoring and analyzing platform to improve and optimize the routines and processes for the cycle to come.
“DokaXact can help build in-situ concrete high-rise cores, bridge piers and pylons more accurately in combination with faster forming times,” said Dan Zvinca, business developer, DokaXact. “The actual position of the formwork is known at all times of the working cycle – starting from the positioning of the formwork to installing the reinforcement, pouring and curing of concrete. DokaXact digitalizes the positioning and monitoring of the entire wall formwork by transforming the traditional formwork survey method.”
