Saglemi Housing Project, Ghana

In Ghana, affordable housing was realized in a very short period of time by means of the monolithic construction method with the UNO Housing Formwork system.
Over 500 complete floors were completed with the UNO Housing Formwork using a monolithic construction method.
The window and door box-outs as well as the beams were integrated in the PERI solution.
After the hardening first the walls, then the slabs were struck.
The lightweight UNO elements together with only a minimum of different individual components simplified the handling and logistics.
The monolithic construction method with the UNO housing formwork allows for the industrialized manufacturing of shell structures. Installation work takes place at the same time as the reinforcement.
The support provided by the PERI specialists shortened the familiarization phase and accelerated the construction sequence.

Project data

Location: Prampram, Ghana

We opted for the UNO Formwork because the system is simple to use and very user-friendly. After a very short time, the floors could be concreted in regular 3-day cycles; as a result, we are able to stay ahead of the originally planned monthly schedule.
