2 Transport Requirements
2.1 Freight-forwarding Company
Transport and unloading is coordinated by a freight-forwarding company. Normally, the freight-forwarding
company will arrange a day for delivery and unloading with the site management two weeks prior to the
planned delivery date.
2.2 Ambient Conditions
The transport route within the PV farm must be designed in such a way that the MV station can be transported
by a semi-trailer. The semi-trailer weighs 60 t with a length of 16 m, a width of 3 m, a height of 5 m and a
ground clearance of 0.25 m. At its final destination, the surface must be dry,solid and even.
The concrete station is lifted off the semi-trailer and set down on the foundation by a crane. The pivoting radius
of the crane is 7 m. The semi-trailer must be positioned as indicated in the following graphic.
If the ambient conditions cannot be fulfilled, it may be necessary to use a larger crane. The final crane size is
determined via a visit to the site.

2.3 Foundation
The building pit and foundation are to be set up on site in accordance with the foundation plan. The following
conditions must be fulfilled:
• The digging depth may not exceed 0.8 m.
• Exterior grounding installations are to be executed according to the instructions of the utility operator or
distribution grid operator.
• The work area must have a minimum circumference of 0.5 m.
• The corners of the building pit must be marked.
• Place the material dug out in such a way that the semi-trailer and the crane are not hindered during
transport.
• The ground must have the following properties:
‒ Approx. 100 mm high
‒ Compression ratio: 98 %
‒ Soil pressure: 150 kN/m²
‒ Planning levels deducted
Remove all obstacles prior to delivery such as fences, power lines, trees and such which could hinder
access by the semi-trailer and crane.
Delivery and transport using a crane of up to 7 m radius are included in the scope of delivery. Additional
costs can be accrued during delivery if
• traffic-control measures such as road blocks, police escorts, etc. are necessary.
• a crane with radius of over 7 m is required.
• an extra traction engine is required for steep inclines.
• excavator mats, etc. are needed.
