Built in Faye-l’Abbesse by Bouygues Batiment Great West, The hospital Center of North Deux-Sèvres will be raised on four levels. The MaxiDalle system, formwork panels Alphi, perfectly matched to this type of work, has been chosen for the construction of the 28 000 m² floor of the building. A new lifting tool, the MaxUpDown, has been developed on this occasion.
The project
The hospital Center of North Deux-Sèvres, scheduled to open
during this spring, will regroup the surgical activity of the three
current hospitals of Parthenay Bressuire and Thouars. It will
accommodate more than 290 beds. The main constructive constraints of
this new building resided in its location in a category 4 seismic zone
and in the density of the structure, constraining its overflight by the
cranes. For this reason, the cast-in-place solution has been favored,
more easily controlled, and more flexible in terms of organization than a
precast-slabs solution.
Safety = productivity
Alphi’s
vision of « designing and manufacturing the most productive products in
terms of productivity through user safety and the fight against
painfulness » is one of the major issues facing Bouygues. Thus, Alphi’s
R&D department was able to provide an innovative and immediate
answer to the question raised by the site manager: “how can we eliminate
the painfulness for the workers when installing and removing the
formwork panels?” So MaxUpDown was born, a tool for lifting the MaxiDalle
which, beyond the removal of manual handling of loads, the fight
against the painfulness and the reduction of the MSD, allows a gain of
productivity of + 33 %.
The point of view of Etienne Poignant
“This was for me the fourth collaboration with Alphi,
the first three projects dealt with the company have been realized with
TopDalle. We enjoyed working again closely with Alphi on this “first” in
MaxiDalle. In fact, we have retained this panel formwork system for the
Hospital Center North Deux-Sèvres for three reasons. Above all –
Safety: Alphi has a good knowledge of the requirements expected by the
Bouygues Group in this domain. The ergonomics side of the material: when
the installation is at 3.80 m high, as it was the case in this site,
the work of the companions is particularly physical and we are attentive
to any initiative to facilitate their work. With this in mind, Alphi
has developed the MaxUpDown. The tool was delivered at the start of the
construction and tested in real configuration, allowing continuous
adjustments and improvement throughout the work. A “win-win”
collaboration! Third argument: the productivity, proven, as the formwork
was laid at a high rate of 150 m²/day to solve a very tight schedule.”
