DNV-GL is currently developing the Basic Design for TenneT into a Final Design for the new lattice masts to be built in the ZWO project. TenneT is supported in this by DNV-GL. The Final Design must then be elaborated into a Performance Design / workshop drawings. TenneT will have the steel profiles for the lattice towers produced on the basis of these workshop drawings.
TenneT wishes to attract three parties through this tender to draw up the Implementation Design (UO) / workshop drawings.
