Netherlands – Works for complete or part construction and civil engineering work – Renovatie binnenvaartkade EECV Dintelhaven noordzijde

HbR aims to extend the lifespan of the inland waterway quay (north side) by at least 25 years and to reduce maintenance and repair costs, with the execution disrupting the client's operations as little as possible. After evaluating various options, HbR has chosen prefabricated facing wall (fibre-reinforced and high-strength concrete) as the preferred variant for renovation. The feasibility of this variant has been investigated by HbR in a feasibility study. The scope of the project realization consists of (non-exhaustive list):

- Installation of a prefabricated facing wall over a length of 600 m of the eastern part of the inland waterway quay

- Repair of holes in the quay wall and filling of hollow space behind the quay wall

- Repair of the drainage of the quay wall

- Installation of a concrete cover slab and associated quay furniture

- Removal of the retaining wall and reinstatement of the raised retaining wall

- Optionally: a similar scope for the eastern part of the inland waterway quay is also possible for the western part of the inland waterway quay, plus the installation of anchors over a length of 300 m.

For the realization of the project, the following activities are expected during the design team phase:

- Optimizing the design of high-strength concrete facing wall with regard to feasibility with limited space between the existing structure

- Mitigating identified risks

- Evaluating the execution method (possibly dry cofferdam or use of caisson)

- Developing phasing in relation to operations at the terminal

Furthermore, HbR expects that during the design team phase, new aspects may come to light that need to be further investigated, which may also affect the scope to ultimately achieve the project result. As a result of the design team phase, the design will be further elaborated in a RAW specification, after which the Contractor may submit a price for this realization. It is noted that the final design may differ from the Preliminary Design as a result of insights gained in the design team. In the ultimate case, a new quay wall must be designed and realized if it turns out that renovation of the quay is not possible for any reason.
