VolkerWessels company Volker Staal en Funderingen (VSF) has won the contract for the underground expansion of the Paleis Het Loo museum in Apeldoorn. The former royal palace will undergo extensive renovation and refurbishment over the next few years. The contract for the underground concrete construction pits, structures and auxiliary structures, and (new) foundations is one of six contracts relating to the total renovation and expansion.
The underground expansion will connect the wings of the existing palace to the main building, the Corps de Logis. The expansion will comprise the addition of a spacious entrance area and new exhibition rooms, creating a splendid ensemble with the palace, the gardens, the exhibition rooms, the Junior Palace for children and the House of Orange, with ample space for both the permanent collection and temporary exhibitions.
The underground expansion of the museum will involve building a construction pit around 10 metres deep and with an area of nearly 4,500 m². This will involve anchoring 4,000 m³ of steel fibre reinforced underwater concrete using around 400 GEWI piles. The 400 meter-long anchored pit walls will be installed around the whole courtyard as well as underneath four sections of the existing monumental buildings. The entire job will involve the excavation of around 45,000 m³ of royal soil.
Construction work for the underground expansion will start in January 2018, with the grand reopening of the fully renovated palace scheduled for the spring of 2021.
