For many decades, the A2 motorway ran straight through Maastricht at ground level, dividing the city in two. This was, of course, an undesirable situation. Yet it took many years before the problem was actually addressed. Ultimately, this resulted in the construction of a unique double-layer tunnel. The roof of the tunnel will be developed as a park to reunite the two halves of the city. Hans Grabandt contributed during the tender phase, working on the winning design on the contractor\u2019s side.<\/p>\n

The Hanzelijn is the new railway line between Lelystad and Zwolle: a 50 km rail connection with crossing infrastructure, a rail tunnel under Lake Drontermeer, modifications to the A6 near Lelystad and the N50\/A50 near Kampen, construction of a new railway bridge over the IJssel in Zwolle, and adjustments to the railway junction at Zwolle. Hans Grabandt was responsible for contract preparation, contracting, and execution of several subcontracts, including the Kampen\u2013Zwolle section and the new IJssel railway bridge. These were among the first major D&C contracts ever tendered in the Netherlands.<\/p>\n

Weirs and locks are vital structures for water level management and have been in use in the Netherlands for centuries. What is new is that the replacement of multiple weirs and the renovation of locks are now being tendered under E&C and D&C contracts. With his extensive expertise in this field, Hans Grabandt took the lead in introducing these contract forms at Waterschap Hollandse Delta for this type of project.<\/p>\n
