HERITAGE

Not only about built heritage

but includes certain distinctive open

areas, neighborhoods, and environs

which are of historical, aesthetic,

cultural or sociological interest and

value which we would like to preserve

for the posterity as they enrich our

history and traditions

CONSERVATION

Conserving and preserving the

Heritage of our historical possession

in its pristine and original form, so

that it continues to portray its original

beauty, distinctive character, unique

style or use or association with a

distinctive historical personality or

event.

CONSERVATION

PRECINCTS

Heritage characteristics to be preserved or conserved are

identified as elevational features, floor heights, cornices, special carvings designs, motifs,

architectural style, roof-scape etc.

PRECINTS

A neighbourhood or an area which has buildings of more or less similar

character, Style or Features, etc. and which collectively have a group value of special features. These provide a unique and distinctive character to such

neighbourhood or area as a whole and need to be preserved.

Examples are- Old village settlements like khotachi Wadi,

THE NEED

The majority of India’s architectural heritage and

sites are unprotected.

They constitute a unique

civilization legacy.

This unprotected heritage

embodies values of

enduring

relevance to contemporary Indian

society.

Conserving the

‘

living

’

heritage,

therefore, offers

the potential ways of conserving a building.

Conserving the unprotected architectural heritage

and sites ensures the

survival of the country

’

s

sense of place and its very character in a

globalizing environment.

This ‘living’ heritage also has

symbiotic

relationships with

the natural environments

within

which it originally evolved.

THE REVITALISATION OF THE

GARDENS OF EMPEROR HUMAYUN’S TOMB,

DELHI, INDIA

(29)

INTRODUCTION

The first privately funded restoration of a World Heritage

Site in India, March 2003

through the joint efforts of the Aga Khan Trust for

Culture (AKTC) and the Archaeological Survey of India

(ASI), under the aegis of the National Culture Fund.

Objective

The objective of the project was to revitalize the garden

according to the original plans of the builders.

(30)

HISTORY

The tomb is one of the 23 World Heritage Sites in India.

The chahâr-bâgh, or four-part paradise garden, is the earliest existing example.

tomb was built over nearly a decade beginning around 1565 (AH 973).

Influenced by Persian architecture.

The architect, Mirak Mirza Ghiyas, was a Persian from Herat, in current-day Afghanistan.

It is the earliest example of the use of red sandstone and white marble in such great quantities.

IMPLEMENTATION

Site works encompassed a variety of disciplines: Archaeological excavation

Application of conservation science Hydraulic engineering.

(31)

Features of implementation

Removal of truckloads of earth (12,000 cubic metres),

Planting of 12 hectares of lawn,

Re-setting and alignment of over 3,500 kilometres of path

kerbstones,

Preparation by some 60 stonecutters of 3,000 metres of

hand-dressed red sandstone slabs (to edge the channels),

Creation of 128 ground-water recharge pits and the de-silting and

creation of other wells.

Creation of a site exhibition,

Planning and installation of a new water-circulation system for the

walkway channels,

Planting of 2,500 trees and plants according to Mughal texts,

Repair of fountains, wells and rainwater-harvesting systems,

Provision of wheelchair access to a significant part of the site.

(32)

Illumination

Documentation

Wells

Earth Removal

Pathway Repair

Pathway surface: Over 25,000 square metres of

pathways in the garden enclosure were repaired.

edging stones: 3,200 metres of the large, Delhi

quartzite, pathway-edging stones were reset.

(33)

(34)

(35)

SUMMARY

The rehabilitation project included the following main elements:

· Reinstating the walkways and conserving the edging stones,

· Repair, extension and reactivation of the irrigation system,

· Establishing water sources for the water channels and irrigation

system, including a pump station for a water-recycling system,

· Conserving, repairing and rebuilding the water channel system,

· Re-leveling the planted zones and revitalizing them with species

and arrangements that conform to the customs and patterns of

Mughal sources.

The core area is conceived as the most valuable section of the precinct. This

area has undergone

minimum transformations

and has survived the urban

demand.

The conservation guidelines for development are as mentioned:

a)

Development plan

The boundaries of Khotachiwadi should be extended.

b) Amalgamation of plots

Clubbing of existing property shall not be permitted as this would lead to

high-rise construction.

c)

Demolition of buildings

No building in the area shall be allowed to demolish and if demolition is

absolutely necessary then the original status should be retained.

(45)

K

To reduce motorized traffic, no road

widening should be permitted as it

might damage the building line and also

The position and placement of the landmarks are to be retained but not necessarily their design.

No additional landmarks shall be permitted. g) Open spaces

All open spaces, whether private or public, shall be maintained. h) The allowable FSI is 1.33.

•Replacement should also be avoided, but if the building is completely in despair, duplication

should be sensitively treated.

(i) Modifications to the façade and architectural features f) Neighborhood landmarks and street shrines

(47)

j) Sign, signage and street furniture

Appropriate street furniture should be added.

K

The entrance to the precinct should be

highlighted by a

signage.

Road names

should appear at the end

of streets, demarcating a one-way or

two-way road.

(48)

As the integral nature of

khotachiwadi is of low-rise cluster of

permitted.

allowed.

(53)

Careful examination of the masonry

reveals different 'periods of construction and repair through the composition and detailing of bricks and mortar

Analyzing the nail technology can help establish the period of construction and provide

other important information.

In many cases, new materials or coverings are placed directly over existing exterior features preserving the original

materials underneath. Here, the removal of a modern shingle roof and its underpayment revealed an historic standing seam

metal roof.

Destructive investigation can be limited to small areas where evidence can be predicted

such as walls being re-built in a different location

Discarded items are routinely stored within attics, then forgotten only to be discovered during a later investigation.

Seemingly worthless debris may help answer many questions.

Raking light is used to show irregularities on flat surfaces.

Patches, repairs, and alterations can then be mapped by the shadows or ghosts they cast

Exploratory testing was used to verify the location of an abandoned fireplace.
