Administrative Centre Soccer Federation - Rio Grande do Sul, Brazil
The building, designed for a regional soccer federation,
has 4 floors, an auditorium, basement, podium and
administrative rooms. The roofs was made with
concrete slabs interconnected with steel domes
The biggest challenge in designing the project was to
set all levels in the right position and the connections
between the precast parts. The project had little
or almost no repetition, and each precast piece
demanded a specific detailing. There were concrete
foundation walls, beams for bleachers, prestressed
hollow core slabs, post-tensioned beams, prestressed
beams, an access ramp, two elevator towers, and a
facade with prestressed hollow core walls in balance,
interaction with steel frames and stairs “in loco”. All
in all, a project extremely complex and difficult to
implement in precast concrete. Besides these factors,
the short deadline for the design, production and
assembly of parts of the structure was a significant
A lot of information was received early in the project:
information about the slabs and stairs that would
be executed “in loco”, the steel structures of roofs
and front facade with glass skin, the machinery of
elevators, etc. Unfortunately, the information was
isolated, not worked into an interconnected system of
information, which made us lose precious time joining
and matching it.
Our strategy was to work to reconcile the initial
information, check the interference and discuss them
with the client and project stakeholders (structural
designer for the “in loco” services, company supplier of
elevators, and architects).
The project design was thorough, preventing errors in
production and assembling of parts. It was possible to
identify several interferences by using the 3D model
Allplan Precast.
The main advantage in using Allplan Precast was
error prevention and identification of interference at
the time of preparing the executive project. Several
cases of incompatibility were identified using the
three-dimensional tool. Several pieces were detailed
quickly because we already had a library with similar
pieces. The design and detailing of prestressed
hollow core walls and prestressed hollow core slabs
were optimised due to software facilities. Using Scia
Engineer was vital for the calculation of post-tensioning
beams. The beams had cables with a parabolic path in
the longitudinal direction, besides the lateral movement
along the length of the beam. This modelling was only
possible with the use of this software.
