Quay wall refurbishment in Hamburg’s Speicherstadt

An urban infrastructure under pressure

The Speicherstadt is more than a historic landmark. It is an interconnected urban system of waterways, built structures, public and commercial uses, tourism, and heritage conservation. When such a system comes under pressure, the issue is not only the physical fabric itself, but also safety, identity, quality of place, and the long-term functionality of the urban environment.

A greater tidal range in the Elbe, human intervention in the ecosystem, and rising sea levels as a result of climate change, along with age-related weakening of the bearing piles and changes to the fleet bed, are all affecting the stability of the quay walls. Here, resilience means the ability to adapt under pressure: a historic structure must be upgraded in a way that ensures it remains robust, safe, and usable in the future—without losing its listed heritage quality.

Resilience through precise planning

For the quay wall refurbishment, Ramboll is responsible for object and structural design across HOAI service phases 1–8, as well as local site supervision and construction management. The refurbishment programme developed combines.

• Tie-back anchoring of the quay walls: Implementation of micropiles up to 30 metres long to stabilise the quay walls
• Raising the current fleet bed by approximately 0.5 to 1 metre
• Ground improvement where required to strengthen the earth support

The result is a solution that goes far beyond straightforward repair: it stabilises a sensitive urban system, protects historic fabric, and strengthens the future viability of an important inner-city area.

The quay wall refurbishment combines technical precision with long-term value for the urban space. The measures enhance structural stability, reduce risks to the historic built fabric, and create the conditions required for the Speicherstadt to continue functioning as a robust, safe, and identity-shaping place in the future.

Added value through integrated thinking

Particularly demanding are the complex geometry and challenging construction conditions of the quay walls. To reliably verify load-bearing capacity and stability, Ramboll uses advanced three-dimensional finite element models. This data-based planning enables precise decisions, limits interventions to what is strictly necessary, and increases the adaptability of the system under changing framework conditions.

A key objective during the refurbishment is to keep the impact of construction works as low as possible. Unavoidable deformations of the quay walls are deliberately minimised in order to protect the historic warehouse buildings above them. In this way, the project safeguards not only structural stability, but also the spatial continuity, quality of place, and recognisability of an urban space that, as part of Hamburg’s UNESCO World Heritage property, is of major cultural and social significance.

Resilient infrastructure emerges where infrastructure, heritage value, the environment, and use are considered together—and where measures create added value beyond their immediate function.
