We are fortunately seeing it more often, our involvement in projects during the design phase. Especially for locations like these, it’s beneficial for us to contribute to devising the best method of foundation.
“The Laamens location, until recently used as a marina, has been redeveloped into a residential and recreational area with 90 apartments, 14 recreational arks and moorings for boats. Given the location and the surroundings, we were able to collaborate with Tervoort Egmond on the most optimal execution method”, according to Sandro Pronk.
In the vicinity of dwelling types A, B, and F, there is existing, older construction present. For this reason, a low-vibration piling system has been considered, in this case, DPA screw piles. The piles are produced on site, screwing into place with the use of concrete and reinforcement. For dwelling type A, where the houses are located adjacent to the water, the piles are partially implemented as mini piles; the piles are formed by connecting small steel segments together and then filling them with concrete reinforced with steel. As this is produced with a mini foundation machine and is therefore lighter in weight, it can operate close to the waterline. For the building blocks D and E, which ultimately stand partially in the Alkmaardermeer on a parking basement, prefab driven piles are used. To do this on dry land, steel sheet piles are first placed, after which the soft soil is excavated and bearing sand is brought in and applied for a load-bearing construction pit. The driven piles are driven one meter deep and, after excavating the basement, shortened by another one and a half meters.
The foundation work at the construction site is scheduled to start in mid-May/June 2024. In total, this will take about eight weeks.
