Old beams and new norms – The conservation of steel structures III

My Session Status

Regular session
3:30 PM, lunes 29 ago 2022 (1 hour 30 minutos)
Break : Sugar Shack Event   05:00 PM to 05:30 PM (30 minutos)

This session is about the “hard facts” of conservation. It aims to draw together technical knowledge from related fields. Industrial conservation specialists rely on specialised knowledge and may sometimes not be aware that there is expertise and proven good or best practice in related fields. The transferring of knowledge from related engineering, construction preservation and architectural conservation specialists can serve the purpose of promoting and securing future preservation of industrial buildings, structures and historic engineering.


Since the 1990s knowledge hast been accumulated amongst practitioners in architecture and building engineering to preserve and deal with historic constructions. Only some of this knowledge and practice has penetrated into Industrial Heritage preservation, despite obviously similar conservation challenges facing steel concrete, thermal efficiency, fire prevention, security and accessibility.

The focus of conservation in both fields is generally adaptive re-use projects, which are than planned and managed under laws and standards designed for new buildings. So, engineers have developed strategies for preservation management to enable the convergence of conservation activity, bringing together safety regulations and norms appropriate for industrial heritage. For example, in Berlin, an old steel bridge was recently measured and analysed by engineerThomas Klähneenabling the modelling of stresses throughout the structure. This model could classify the bridge under a contemporary norm (DIN-EN). These resulting predictive models made it possible to keep the bridge in use and permitted its renovation with only minimal changes. Such management methods and techniques may be transmitted from one field to another. This session will therefore bring knowledge from engineers who have not necessarily worked in industrial heritage preservation to industrial heritage engineering specialists participating in the TICCIH 2021 conference. The session also brings them together to promote bilateral cooperation.

This second block of the two-parts session addresses the challenges of steel coatings.

Coatings play a fundamental role in Engineering Heritage Conservation, raising questions differing greatly from problems perceived in conventional industrial coating techniques. 

In this section we will come to the coating of the Pont the Québec with the Termarust technology, an inhibitor-based system specifically designed to deal with structure critical components which often occur in historical steel works. We will also show new trials in the pigmented or unpigmented coating of harbour cranes, likewise relying on inhibitive corrosion control.

Industrial heritage holds big challenges for conservators, being mostly exposed to free weathering conditions. Often industrial methods are chosen for the protection of historic industrial structures. They are carried out following modern engineer standards: the surface of steel objects is cleaned to create a homogenous substrate which is then coated in several layers. However, overcoating is a delicate topic. Modern...
