“...counter argument which is in favour of restoration because of the functions served by the Tower prior to its collapse, but most importantly its cultural significance since many architectural landmarks become associated with the identity of the city they are located in. In case there are compelling reasons for restoration, the questions worthy of answer are: what strategy should be adopted for restoration? Should it be restored to its original design, shape and size? What should be the choice of materials in order to prevent its collapse in the future? What structural aspects need to be improved to withstand earthquakes of similar magnitude in future and how? These are some of the aspects that need to be pondered upon, if restoration is the most suitable option.
Not very far from Kathmandu (only about 235 km) is the ancient city of Patna, the capital of the Indian state of Bihar which has its northern boundary adjoining the Himalayan nation. This boundary is located along the junction of the...”

“...minimizes damage by preventing its components to work against each other.
Temporal discontinuities in restoration are liable to cause
natural breaks in construction, putting a question mark on behavioural strength and stability of buildings. Hence this architectural legacy, reminiscent of the reign of one of the greatest Master Builders of India in the historic city of Patna may still be seismically vulnerable. Inappropriate restoration without due architectural consideration in terms of style, materials used changes in structural elements and altering the shapes and sized of its parts and embellishments has also reduced its architectural value and its potential for tourism.
2. Gol Ghar, Patna (1786)
This granary was constructed in response to the devastating famine of 1770 in which nearly 10 million people had died of starvation in Bihar and Bengal. Warren Hastings, the Governor-General of India at that time, ordered its construction for storing grains for the British Army. Designed in Stupa...”

“...post-disaster damage review. Appropriate restoration of buildings damaged by earthquakes can only be done if comprehensive prior documentation of the buildings is carried out and such documents are made readily available to all stakeholders.
Architectural and structural drawings with measurements, details of the construction materials and specifications of each heritage structure must be prepared, supported by photography, videography and descriptive text to include structural design, structural systems and construction techniques used, detailed documentation of its architectural styles, sizes and shapes of its components, its history, year of first construction, age, materials used, details of restorations carried out, if any, along with evaluation of structural conditions of various parts. This may be used not only as a guide towards retrofitting of those heritage buildings which have higher probability of damage or for their restoration in case of damage. For these The Handbook

“...changes are acceptable, drastic changes in the interiors may lead to some loss in its architectural value.
Change in materials and finishes: Preserving authenticity of elements, features and materials is an important aspect of restoration which may pose several challenges with traditional masonry structures subjected to earthquakes. At times, it becomes necessary to use materials different from those used during original construction, particularly for repair or structural strengthening or during refurbishment required for a changed function. However, it must be ensured that the substitutes used are durable as well as compatible.
Familiarity with latest researches: Extensive experimental, theoretical and computational researches have made available several alternative solutions to structural problems.31 There is a deluge of literature available on the different materials and techniques that can be applied for

“...Necessity of proper supervision and inspection: It is a
well-established fact that even the most perfect of structural designs can be flawed if it is not executed properly. Therefore, meticulous supervision of construction works must be done by professional architects and engineers on regular basis along with frequent inspections to ensure that all relevant codes are followed and to ensure materials and workmanship for ensuring its strength and stability.
Ensuring revenue generation for self-sustenance:
Restoration costs are usually much higher than fresh construction since restoration requires materials, craftsmanship and labour, particularly those that were prevalent in a bygone era. High cost is generally a deterrent in restoration and becomes particularly prohibitive in developing countries such as India. Hence, proposal for restoration must provide mechanism that supports not only cost recovery, but also generates revenue for regular operation and maintenance so that they do not remain...”
