Remedial works to heritage structures bring similar pressures to any other project, specifically the need to deliver resilient and cost-effective solutions. But there are added dimensions that shift the emphasis of project delivery.
At the core is the need to apply the constraints and advantages of modern construction standards while preserving the character and integrity of the original structure.
Suttle Projects is frequently asked to carry out repairs and reconstruction of harbour walls and sea defences with an important heritage status. Here’s a brief snapshot of what we’ve learned.
Embrace The Heritage
Every civil engineering project has to be empathetic with its surroundings, with heritage structures this need is even more acute.
There’s a rich history and character that make the structure more significant than its simple function. A harbour wall in an historic dockyard is an integral part of the site’s narrative. That story is the starting point. There’s no blank canvas for designers to work with.
Resolving structural flaws and risks, for example with seawalls designed to resist coastal erosion, always has to be done in the context of preserving what’s special and unique.
Collaborate, And Keep Collaborating
Heritage and environmental groups are the guardians of the heritage. We need their help to understand the story and the significance of particular features. Collaboration needs to happen early and often with conservation officers, harbour commissioners and local interest groups to accommodate their priorities into the design.
Temporary Works Are Sensitive
Heritage structures bring added complications to the design of temporary works. We take great care to ensure that scaffolding, working platforms, cofferdams and other structures don’t overload or undermine potentially fragile building fabric.
These considerations extend to methods, machinery and fixing details we are able to use to ensure, for example, that excessive vibration does not weaken the surrounding structures. We also have to remain sensitive to the overall visual impact of temporary works.
Compatible Materials
However robust and resilient the repair, nobody’s going to thank us if it sticks out as an out-of-context eyesore. The methods and materials used in the original construction typically govern our choices. So our supply chain includes relevant specialists in traditional crafts such as stonemasonry.
Live Environments
Heritage structures such as harbour walls and bridges are still working assets that people rely on. So we typically plan for safe working in a live environment. This demands careful project phasing, traffic and pedestrian management, and clear communication with stakeholders so heritage assets stay safe and accessible while works progress.
