WHAT IS MONUMENT RESTORATION??• It is an endeavor that seeks to

preserve, conserve and protect buildings, objects, landscapes or other artifacts of historical significance.

• It has many other names for the discipline or sub-disciplines

WHY RESTORE MONUMENTS ??• Decay is inevitable by law of nature. As construction

engineers, what we can do is to delay the process of decay. The restoration of old buildings represents an ecologically and economically valuable contribution to the quality of life.

HISTORY• Francesco petrarch (1307

– 74)

• The first Ancient Monuments Protection Act was adopted in 1882.

• PRESERVATION

• RESTORATION

• CLEANING

STEPS FOR RESTORING MONUMENTS

• Assess the monument's setting and condition.

• Look for evidence of ground settling, overgrown vegetation and water-runoff.

• Gentle cleaning

• Begin cleaning by removing loose debris with a soft-bristled brush.

• Use a weak cleaning solution if necessary. Orvus detergent is probably the least likely to cause damage to the monument's surface. Ammonia can be used on marble.

• Reset monuments that have sunken into the ground, but first have a plan ready for temporarily moving the monument as safely as possible.

• Hire a professional mason conservator to make any repairs.

• Seek recommendations for a qualified professional from the state historic preservation office, local museums, monument preservation firms, and monument manufacturers.

PAINT RESTORATION• If a painting is conserved relatively well, only

exfoliation-preventive measures are taken and no colors are added.

• New replacement wooden parts are painted to look old so that they cannot be immediately distinguished from the original parts.

• Exterior lacquer is mainly re-applied, and colors are also repainted in the original colors.

• If an original pattern is identified through minute study, even if it is badly exfoliated, some parts may be restored to their original colors.

• Reproductions and sketches of wall paintings and decorative patterns are created to retain records of the original state.

PAINT RESTORATION

SOME DO’S AND DONT’S• While cleaning can greatly improve a monument's appearance,

regular cleaning is not recommended as each cleaning episode is a potential cause of damage. The American Association of State and Local History recommends cleaning only once every several years.

• As a rule, it is best to leave a monument in its original location (especially grave markers). Only relocate if it is severely threatened. Moving a monument removes much of its historical integrity.

• Although we all hate to see monuments in poor condition, it is better to do nothing than to attempt an unskilled restoration and cause more harm over time.

METHODOLOGY FOLLOWED FOR RESTORATION

ISCARSAHOBJECTIVES:• To promote international cooperation in the establishment of a world

body gathering the various specializations of professionals in conservation and restoration concerned with integrating the contribution of structural engineering into conservation knowledge, so that a full understanding of structural typology and behaviour and of material characteristics become an intrinsic part of conservation practice.

• To establish guidelines and/or to formulate general recommendations to be regularly updated.

• To disseminate the knowledge acquired for the development of cempetency in conservation of historic structures in different countries.

EXAMPLE

• A comprehensive plan for restoration of the Samba Fort has been conceived at an estimated cost of over Rs 4.87 crore as part of efforts to preserve historic places by Jammu and Kashmir government.

• Over Rs 75 lakh have been spent on various works for the restoration of the fort believed to be first constructed in 13th century AD

• The government undertook restoration and conservation programme in March 2010.

• The works so far undertaken include partial restoration of outer fort wall, restoration of water tank, clearance of wild vegetation inside and outside the fort

RESTORATION OF RED FORT – NEW DELHI

• Delhi's Red Fort, where Mughal emperors ruled and Nehru made his first speech to independent India, is undergoing a makeover after conservationists discovered much of the world heritage site was actually originally white.

• According to conservation architects the symbol of Mughal power and Indian independence should be known as the 'Red and White fort' for the combination of colours favoured by its creator Shah Jahan.

• Craftsmen are now restoring three key buildings to its original colour with a traditional white 'Mughal plaster' made from ground marble, dhal pulses, lime and fruit juice after a study found they had been painted red in the mid-nineteenth century.

CONCLUSION• Constraints to be considered in the use of advanced modeling

are the cost , the need of an experienced user / engineer, the level of accuracy required, the availability of input data, the need for validation and the use of the results.

• The key message is that research and innovation are strongly needed to assess the vulnerability of existing constructions and to define economical rational strengthening approaches. Without this, the ancient household and the preservation of the architectural heritage remain at risk.
