NHIG needs your help! In 2013 NHIG published its 15 Conservation Principles and is now endeavouring to create an illustrated guide to these. In order to achieve this we need real life photographic evidence. If you are able to contribute to this please send us photographs of any relevant work with a brief description. We will do the editing. As can be seen some of these principles will not be easy to evidence by photographs alone, so if you are able to contribute other information that could be useful it will be much appreciated.
If you are able to contribute a complete case study we would be extremely grateful.
Can you help NHIG with this project?
Do you have any images that illustrate the NHIG Conservation Principles?
- Consideration and understanding of significance: Significance is the historic, aesthetic, technological or social value for past, present or future generations.
- Retention of as much existing material as possible: This is a fundamental requirement of conservation work and takes priority over cost, serviceability and aesthetics.
- Use of techniques and materials as originally used: Details of the original materials and techniques used should be identified and preferably adopted for new parts.
- New material should be identifiable: The name of the Conservator and the date of the work should be identified on replacement components where practical.
- Parts and materials that cannot be re-used: Components, including wasted / rusted fragments, and samples of original materials that cannot be retained in use, must be stored in a secure and stable environment, preferably close to where they originated.
- Improvement of immediate environment: Where practicable, the environment of historic ironwork should be improved by protection from the elements
- Relocation to a less destructive environment: Historic ironwork should be retained in its original location, protected from damage, deterioration and theft.
- Protection of surfaces: The corrosion of surfaces is a threat to the survival of ironwork in an exposed environment
- Use of additional materials or structure for strength or support: Where ironwork is weakened or subject to increased stresses that cannot be relieved, structures may be strengthened by applying additional props, stays, ties or materials bonded on.
- Use of replicas: In exceptional circumstances use of replicas may be considered, for example where ironwork is subject to wear, or is at risk of serious damage and corrosion or theft, its on-going preservation may best be achieved by creating a replica, and retiring the original from service.
- Planned maintenance: Maintenance is vital to minimise the rate of deterioration of historic materials.
- Selection and proper training of suitable practitioners: Craftspeople, managers and professionals must be competent in the theory and practice of ironwork conservation.
- Detailed recording: An historic object, and all work to it, must be recorded before, during and after conservation.
- Comprehensive written maintenance schedules and operation guidelines: These are needed to facilitate planned maintenance and minimise the potential deterioration and damage to historic ironwork and the danger to those who use or come into contact with the ironwork.
- Specification of all stages of work in accordance with good conservation practice: Specifications, drawings and schedules of work define the scope and standard of work required and provide a basis for payment.
