What was done
Plumbing renovation to 70s element concrete apartment building. The project consisted of renewal of sewage and fresh water lines, new surfaces and and water proofing to bathrooms. The walls were also redone because the old metal elements bathrooms were removed.
How it was done
The project was done with 1 day takt length, and a takt area of one apartment. The working was executed from top to bottom on each line. Almost all of the work inside the apartments was done with takt time, starting from the demolition.
The success of takt time production methods required efforts in establishing routines for takt control. Daily meetings, and early involvement of subcontractors in takt time scheduling were major success factors for the project.
“The use of takt time highlighted the need for good preparation of work. Design, resources and previous work had to be made ready on time. A good tool to keep everybody on the project up to date was to have meetings every morning. The one day takt length definitely showed its sensitivity and challenges, but it also proved the potential of takt time. Takt is a good base for production development.”
- Jarmo Mattsson, supervisor, Respect Project
Archieved the following reductions in working times:
Per apartment: traditional 10 weeks versus takt 5-8 weeks
Per whole project: traditional 12 months versus takt 6 months
Thanks to the good results in the project, Respect Project started to implementing takt time in all of their projects. While doing that, they decided to start implementing takt also in projects without clear repetitiveness, to increase stability and risk control.
