Activities for renovation and new construction for maintenance on trains The project "Nieuwbouw Onderhoudsbedrijf Leidschendam" (New Construction Maintenance Company Leidschendam) comprises the main activities for the demolition and renovation and new construction of the NedTrain Maintenance Company in Leidschendam. These modifications will enable NedTrain in Leidschendam to carry out maintenance on new and extra trains.

The work for Strukton Milieutechniek consisted of the remediation of the heavily contaminated soil with heavy metals, PAH, mineral oil and asbestos. And the groundwork for the construction pit, the construction of waste water and rainwater drainage, oil separator and paving, including the associated work such as design, permits and drainage.

The construction work for the renovation of the NedTrain maintenance warehouse could be completed within the set deadlines.

Soil remediation Leidschendam


The soil remediation has been carried out safely and in accordance with current legislation and regulations. Partly as a result of Strukton Milieutechniek's contribution, the construction work for the renovation and new construction of the maintenance warehouse for NedTrain was completed within the set deadlines and NedTrain is able to carry out maintenance on its equipment here.

The work was carried out on the NedTrain Leidschendam yard, while part of the site was still in use.

Implementation while the site was still in use The work was carried out on the NedTrain Leidschendam yard, while part of the site was still in use. The cofferdam was excavated in phases, while the sheet piling was installed and the cellars and floor were already partly poured. The groundwater level reduction for the excavation pit was monitored online. Due to the poor accessibility of the site, a great deal of coordination was required with regard to the execution of the work. Strukton Milieutechniek took care of the notifications and permits for the work it carried out, but also drew up the design and the as-built drawings.
