E. Klink, the HVAC team of the Per Aarsleff Group, is a pioneer in the field of building and maintaining energy-optimised ventilation systems. For over 75 years, the company has performed ventilation undertakings on some of Denmark's most complex construction projects, ranging from hospitals and laboratories, to enterprise HQs and museums.
In 2019, the company launched a new initiative called Digital Design with 3D BIM technology, with the aim to ensure high quality during the project design phase.
However, throughout the actual construction phase, site inspections for quality control of piping systems and air terminals were still majorly done through manual spot checks. These methods are too slow and subjective to document the As Built status, covering only a small percentage of the entire project. As a result, these bore a high risk of issues staying overlooked, with severe complications and costs surfacing only later in the project.
While looking for better ways of conducting construction site inspections during the building phase and mitigate this risk, E.Klink learned about the Norwegian technology company Imerso.
In two projects spanning over 110 000 m2, Imerso analysed laser scans taken by E. Klink’s own teams. This allowed immediate verification that ducts and air terminals are located correctly, by comparing the As-Built status directly to corresponding BIM models and highlighting work deviations.
