Website
Baudin Chateauneuf was founded in 1919. From its beginnings in the
production of electrical towers and farm sheds, the company moved into
the construction of steel bridges. In 1954, the company sought to diversify
its activity. Its mastery of metal logically led Baudin into the field of metal
frames. Nowadays Baudin offers a full range of services at the highest
technological level in a lot of business areas: construction and renovation
of civil engineering work, steel structures, mechanical engineering and as
a general contractor.

Construction Period 09/2014 - 06/2016
As a part of the building of the Cité Musicale in Boulogne-Billancourt
near Paris, Baudin is responsible for this special project. These are two
symmetrical three-dimensional truss structures composed of tubular
connections. Each one is 18 m long and more than 40 m high. These
structures support 880 m
2
of photovoltaic panels. The crucial aspect is the
motorization, which enables the structure to follow the path of the sun.
The first difficulty encountered was due to the complex shape of the
structure. The model was designed in SCIA Engineer on the basis of the
CAD file of the architect. The DWG file was transferred to SCIA Engineer.
The intensities of wind loads on the photovoltaic panels were
determined by wind tunnel tests. It represents 146 wind load cases for
302 photovoltaic panels. The wind, excluding all other cases of loads,
represents 132276 point-loads. This data was imported into the design
model using the Table Input tool.
The possibility to input files was a big advantage, as it enabled the 3D
structure to be formed quickly, easily and exactly in SCIA Engineer.
Production will start in spring and will be followed by the assembly on
the site in September 2015. In this way Baudin will demonstrate its
multidisciplinary competence in carrying out a new “above-standards”
construction work.
