DokaXact is a tool for surveyors and crews, which allow site teams to quickly and precisely plumb and align wall formwork used with core formwork climbing systems. It consists of a wireless centralised processing unit, which communicates with multiple sensors attached to defined surveying points of the wall formwork.
When calculating the required position of formwork elements, the actual known as-built of the preceding casting section serves as the base, then the DokaXact app provides the site crew with instructions during the positioning process so that the formwork is plumbed and aligned with pin-point precision for the next casting section. By accessing the cloud, all stakeholders are able to view and record the live information related to plumbing and alignment, regardless of location.
The live monitoring function can also show how all measuring points in the same formwork section change when individual measuring points are plumbed and aligned. This is not an option when aligning formwork points with traditional sequential methods. The sensor system is accurate down to ± 2mm, therefore allowing the structure to be built more easily within the predefined structure tolerances. Time-consuming finishing work and resulting expenses for subsequent trades, such as from lift installers, are reduced.
The system’s intuitive operation gives site crews more autonomy when plumbing and aligning formwork of highrise cores. This process yields up to 75% savings in surveying services, as the majority of plumbing work can be undertaken without the need for a surveyor. The surveyor is most typically only required now for the as-built surveying, thus accelerating casting section production and potentially reducing downtime while inspectors attend. Digitising the process of plumbing and aligning the formwork also allows for seamless documentation that can be accessed by defined user groups regardless of time and location.
