Basel: Topping-out ceremony for office tower Bau 2
High, higher, build 2! Now it’s official: the “Bau 2” high-rise project by F. Hoffmann La Roche in Basel – for which omniCon is responsible for construction management – is the tallest building in Switzerland at 205 meters. On December 1, 2020, the last concrete for the building designed by Herzog & de Meuron was poured and the shell was completed. A whole two months ahead of schedule. How was that possible?
“The consistent use of innovative and agile planning and control tools has a positive effect,” reports omniCon project manager Michael Horn.
This is largely due to Roche, a building owner open to innovation. The task for all project participants was to introduce the most modern and innovative methods currently available and to use them consistently to increase efficiency. “Even now, just over a year before construction is due to be completed, we are already seeing a significantly lower number of addenda or delays than in comparable projects in the past”. The project partners are also asked to measure and evaluate the effect of the new tools. In this way, the methods can be further developed and the findings can still be used in the project.
omniCon is responsible for the construction management and is therefore not only in an advisory capacity responsible for the tendering and awarding of all planning and implementation trades, but also for the control and smooth operation on the construction site. An essential tool in all processes from planning to implementation and the elimination of defects is the digital BIM methodology. The digital simulation of the building and all construction processes is used for planning meetings on the large screen as well as for mobile site inspections on the tablet. Not only planning errors can be identified much faster this way. Also the effects of changes in planning become immediately visible, economically, technically and also in their consequence on the construction schedule. To optimize the construction process, the agile “Lean Construction Management” methodology is also used in Bau 2.
“The whole project is a highlight,” summarizes Michael Horn.
“We work here with forward-looking methods that deliver measurable results. And working with this team is pure joy”. The trusting partnership between omniCon and the client Roche has now been in place for ten years – Bau 2 is already the second joint high-rise project after the neighbouring Bau 1. omniCon is on site with around 35 employees.
