4. PERFORMING THE CIVIL ENGINEERING WORK
The purpose of this part about civil engineering works is to define the general principles of construction and
the time schedule for building the shell required to install the Xpedia 360 EX External Rotary Milking Parlour. It
specifies the geometric and mechanical parameters to be adopted in order to complete this shell, as well as the
required characteristics of the materials (concrete and steel) for building the various parts (foundations, walls,
apron, flooring). The system must be installed according to the technical description given in this manual so as to
precisely define the system’s geometric parameters (depending on the number of cows on the rotating apron).
Throughout this manual, X will indicate the diameter in mm, of the outer curb of the rotating apron.

The external rotary system is characterized by the fact that the operator stands outside the rotating apron on
which the cows are positioned. The general level of the concrete floor of the milking parlour is level with the
operator’s feet, that is, about 1050mm below the level of the rotating apron on which the cows are standing. The
cows are arranged radially on the rotating apron with their heads facing inwards into the circle. An access platform
with a shoulder wall and a finished height of 1050mm must be created between the “Holding Pen/Return Corridor”
and the “Milking Parlour” area to allow the cows to access the apron.
The procedure for building the shell is as follows:
1. Generally excavating the milking parlour to a level of -1250mm/finished level of outer edge of rotating
apron.
2. Excavating a 1000mm wide 200mm deep circular strip footing to support the metalwork of the rotating
apron. The external radius of the footing is Rext=X/2-550mm and the internal radius of the footing is
Rint=X/2-1150mm.
3. Digging trenches and running seven 40mm diameter internal electrical conduits connecting the machine
room (plant room) to the milking parlour.
Two conduits allow each of the drive motors to be connected to the machine rooms, two conduits connect
the detection cells to the machine room, one conduit connects the milking station to the machine room, a
sixth conduit connects the cow entry and exit gates to the machine room, and a seventh conduit connects
the safety panel to the machine room (see Figure 4).
These trenches can also be used to run the water-supply conduits to the milking parlour from the machine
room (washing the platforms) as well as a copper cable, providing the general earth for the milking system
(cross-section of the copper cable to be determined by the milking equipment fitter).
All of the reinforced concrete reinforcing bars (reinforcements for the footings, walls and floor slabs), as well
as all the metal parts that form the machine’s framework, must be connected to this single earthing line.
4. Digging trenches and running 125mm diameter PVC wastewater (washing) pipes from the milking parlour
to a slurry storage pit. There will be four evacuation outlets at the bottom of the milking pit whose axes will
lie on a circle with a radius of R=X/2-1800mm and will be arranged round two perpendicular diameters.
5. Installing the reinforcements for the circular footing. The reinforcements for the circular footing will
comprise 6mm diameter, 900mm wide, 300mm high HBS steel deformed-bar frames, arranged radially
every 200mm, plus ten 8mm diameter HBS steel deformed-bar fe E 500 curved strip rods.
Five of the strip rods will be welded to the bottom of the frames and five to the top of the frames. These
