Betonmast is an innovative Norwegian turnkey contractor delivering all types of residential and commercial buildings. Established in 1995, the company has grown to become one of the largest construction companies in Norway, with expertise in building residential and commercial buildings, infrastructure, and renovation projects, and a focus on lean and digital construction.
The team around Head of Innovation Christopher Carlsen are always on the lookout to improve existing workflows with novel methods and technology, on the road toward a more efficient digital construction process.
Challenges with Structural and Prefabricated Constructions
A critical area has long been the installation of prefabricated concrete elements early in a project. Often, subcontractors are ordered to deliver pre-built structural elements such as slabs, walls and ceilings. These elements have tight contractual tolerances in terms of headroom, angles, and cracks, that must ensure a perfect fit to the built reality onsite.
Deviations from these tolerances have a range of consequences such as the need for leveling floors, different painting work, or even the redesign or re-engineering of entire setups. Overlooked errors made during this phase have costly impacts on the following phases that affect the entire project.
Betonmast bears the risk of extra expenses associated with delays, daily fines, rescheduling, extra work and material, and legal action. To avoid this, Carlsen seeks to ensure that the concrete works are delivered as planned, within the specified tolerances, and before the next construction phase begins.
Outdated construction site inspections
The company's typical approach to construction quality inspection in the past was to use a combination of checklists, spot checks, as well as manual surveys in areas where these methods are possible to carry out. The onsite teams would mark work changes with red-line As Built drawings combined with photo documentation.
“The quality control process was so time-consuming that only 10-15% of the total areas got controlled in this way. If the first inspections don't reveal discrepancies, the scope of inspections is further reduced. This leaves significant blind spots for areas without the necessary control." - Christopher Carlsen, Head of Innovation.
