Criteria for Listing Heritage Building
The three key concepts need to be understood to determine whether a property is worthy of
listing.
1. Historic significance : It is the importance of a property to the history, architecture,
archaeology, engineering or culture of a community, region or nation.
2. Historic integrity : Property must be unique and have historic identity, evidenced by the
survival of physical characteristics that existed during the property's historic period.
3. Historic context : It is information about historic trends and properties grouped by an
important theme in the history of a community, region or nation during a particular period
of time.
4
Methodology for Listing :
1. Background research : It helps in identifying historic areas, historic developments in the
area, significance of the events that may have taken place at different times, important
persons who may have shaped historical developments, cultural developments, and similar
features that may be unique to the area.
2. Field work : Field work requires lot of work to scan the heritage properties and recording
information for each property in the prescribed format. This comprises of physically
inspecting the property as well as meeting local people such as owners of the property,
talking to other residents and local ward or panchayat members, and knowledgeable
residents and representatives of institutions.

Current Status
The grand central staircase is
extensively used and the corner
staircases are redundant – they are
inadvertently used as solid garbage
chutes
• Building undergoes degradation due to climatic and environmental changes
• Also degraded due to over stressed services (electrical, water-supply, sanitary, rain-water
drainage, fire-fighting, air-conditioning, solid waste disposal)
• These problems can be seen through visual inspection.
The Malad stones and more particularly the
limestone on all the elevations are unevenly
stained and in places architectural features
are hidden due to incongruous additions and
alterations caused due to emergent
necessities

Conservation Plan for CSMT Heritage Building
• Building - Truly historical and irreplaceable, intelligently designed and diligently constructed.
• Inspection - Visual inspection and laboratory analysis of the building stones.
• Disintegration cause - Physical, mechanical and chemical forces of nature & the man-made
problems of improper and inadequate repair, maintenance and use. The aggressive climate
and highly polluted micro environment of the traffic-ridden Mumbai, have left their tell tales
on the building fabric in the form of broken / cracked / eroded / disfigured / chemically
degraded stones ( particularly the reactive Marble & Lime stone ), precarious stain glass,
leaking roof structure, etc.
24
25
• A team of conservation architects, specialist engineers, architects, material scientists, and
historians was assembled for the work.
• Duration of Survey – 8 months (during both wet and dry conditions)
• Focuses on serious, services, structural, architectural and other problems.
• Only the C.S.T. main building and the platform no 1 towards Crawford market have been
detailed for surveys although the entire complex is a heritage site. This was done due to
constraints of time etc.
• The authentic principle and technique of repair is described with respect to typical
problems. The principle of 'Repair and avoid restoring' and 'repair with honesty, using like-
materials (same materials) where possible has been advocated echoing the best traditions
of conservation. 25
Brief Methodology of Plan
Conservation Principles
• A comprehensive awareness of the needs and clear approach to achieve the same aura of
the old and historical, & remainders of the past / passing era, that will be of educational /
cultural / socioeconomical value to the on-coming generations is the basic prerequisite for
any conservation activity.
• Conservation primarily, is a process which leads to the prolongation of the life of the cultural
property for its utilization now and in the future. All practical alternatives should be
explored and then evaluated in the light of theory in order to find the ‘least bad’ solution,
which must respect the qualities in the historic building.
26 26
Conservation Principles
Preservation:
Prolonging the life in its existing form by minimising intervention, this is the purest form of
conserving a heritage building and calls for high degree of restraint and tolerance
Redevelopment:
When in the case of extreme danger to the stability of the structure or for any other reason, the
whole building is rebuilt or extensively changed, it is termed redevelopment.
Restoration:
Technical term for authentic repairs includes specific necessary / inevitable interventions
conducted on a heritage building, covering routine to unique methods. The cleaning of buildings
is also a form of restoration and the displacement of missing decorative elements is another
Rehabilitation:
It is always desirable that the reuse shall be same as the designed use or in case of change of use
to squatting etc., to a compatible one.
27
Proposed concept of long term conservation plan
• It is proposed that a committee of the Central Railways under the chairmanship of the General
Manager, Central Rly. could coordinate the internationally significant conservation project.
• This could be done using a special conservation fund with inputs from public, private
international sources, if needed.
Restoration proposals:
The conservation project managers, nodal agency who will co-ordinate the entire
implementation of the plan besides being QA/QC agency. The specialised works such as the
building services modernisation needs to be planned with the additional expertise of the nodal
agency

WALLS
Due to leaking the plaster is in poor condition at many places, especially in the toilet
areas & verandas of the second floor. The plaster in these places needs to be chipped
off and repaired with a matching (1:3 lime putty, river sand) site prepared and stored lime
mortar in two layers. A bonding agent is useful for adhering new and old materials
STONE WEATHERING
• For limestone lime washing is recommended where major weathering of rocks are seen.
• Stone pointing should be done where ever joints are seen open.
• Stone cleaning 1 in 10 years should be done. And spot cleaning is preferred to total cleaning
• Minor surface consolidations can be done on stone cracks
33 33
FLOORS
The conservation needs require that all the tiles used should
be uniform and shall blend with the architecture of the
building. The choice will be made by the relevant
appropriate authority through the nodal agency proposed.
PAINTING DEFECTS
Paints Peeling off due to improper surface preparation
• Whitewashing to be done annually In the month of
October. In utility areas i.e. Toilets, kitchen
• Repairs of plaster should be done with lime mortar, if
necessary with the help of organic polymer binder.
34
TIMBER
Damaged timber to be removed and replaced with matching recycled timber General guidelines
• Anti-termite and wood preservative treatment, varnish and paint system - to be applied once a
year.
• Flat oil paint/lead based paint to be applied to the exterior wood.
METALS
• All metal surfaces should be painted with metal paints once in three years.
• Use of mild steel should be avoided in this building for corrosion instead non-ferrous plastic
metals are to be used like stainless steel, galvanised iron, copper.
35
36
ELECTRICAL SYSTEM
• Restoration and checking of earth-pits at substation and preventing leakages in the substation.
• Correcting the defects in the L.T. distribution panels.
• Replacing old wiring. It is strongly recommended that instead of doing a patchwork, total
electrical system for the whole building should be designed and implemented.
• Open wiring in corridors should be placed in box type channel throughout the building.
• Optionally, installation of capacitor-bank and Power Factor Monitoring Equipment to improve
P.F. of installation and save energy.
• Following tests for the installations safety should be carried out at the earliest:
a) Insulation resistance test
b) Earth Continuity test
36
WATER SUPPLY SYSTEM
• The whole of the water supply to the plumbing apparatus is required to be redesigned and the
distribution should be done through 2 centralised overhead tanks and a well designed terrace
loop system using non corrosive pipes having ultra violet rays stabilising properties.
• Internal water supply: Internal water supply inside the toilets also need total restoration as the
pipes used for feeding the apparatuses are very old. The piping should be concealed as
exposed piping is always subject to tempering and damage. The internal plumbing
should be either of 99.9% percent pure copper pipes of 0.9 mm thickness and of
bendable quality, minimising joints and avoiding the tempering.
• Vertical external drainage system: Vent, rainwater pipes etc. are also very old and
needs replacements in some cases.
37 37
38
PLUMBING AND SANITATION
• The present plumbing pattern is not only unorganised, but is also visually disturbing as
exposed pipes are seen in the main circulation corridors and on the main facade of the
building. Some pipes are seen to be running along the floor on the second floor where the
toilets are situated in the centre of space.
• Detailed plumbing plan has to be prepared for the building with a thorough mapping of all the
water outlets, rainwater discharge pipes and other plumbing fixtures. It is observed that the
position of the water tanks all along the flat areas of the terrace causes excess dead load,
hence showing distress in the timber joists on the second floor. These should ideally be
accommodated within one overhead tank fulfilling the water requirements for the entire
building.
38
AIR CONDITIONING
A.C. Window units shall be replaced by split A.C. units
in the long run as the AC window units may impact
load and obstruct natural air and light from
environment

All practical alternatives should be explored and then evaluated in the light of theory in order to find the ‘least bad’ solution, which must respect the qualities in the historic building. 26 26

    Conservation Principles Preservation: Prolonging thelife in its existing form by minimising intervention, this is the purest form of conserving a heritage building and calls for high degree of restraint and tolerance Redevelopment: When in the case of extreme danger to the stability of the structure or for any other reason, the whole building is rebuilt or extensively changed, it is termed redevelopment. Restoration: Technical term for authentic repairs includes specific necessary / inevitable interventions conducted on a heritage building, covering routine to unique methods. The cleaning of buildings is also a form of restoration and the displacement of missing decorative elements is another Rehabilitation: It is always desirable that the reuse shall be same as the designed use or in case of change of use to squatting etc., to a compatible one. 27

    Proposed concept oflong term conservation plan • It is proposed that a committee of the Central Railways under the chairmanship of the General Manager, Central Rly. could coordinate the internationally significant conservation project. • This could be done using a special conservation fund with inputs from public, private international sources, if needed. Restoration proposals: The conservation project managers, nodal agency who will co-ordinate the entire implementation of the plan besides being QA/QC agency. The specialised works such as the building services modernisation needs to be planned with the additional expertise of the nodal agency Roof - (sloping, flat terrace, ground surface), Floors, Walls, Finishings and interiors, Services such as - (i) Electrical (ii) Water supply (iii) Sanitary/plumbing (iv) Air-conditioning (v) Fire-fighting (vi) Landscaping and parking 28

    WALLS Due to leakingthe plaster is in poor condition at many places, especially in the toilet areas & verandas of the second floor. The plaster in these places needs to be chipped off and repaired with a matching (1:3 lime putty, river sand) site prepared and stored lime mortar in two layers. A bonding agent is useful for adhering new and old materials STONE WEATHERING • For limestone lime washing is recommended where major weathering of rocks are seen. • Stone pointing should be done where ever joints are seen open. • Stone cleaning 1 in 10 years should be done. And spot cleaning is preferred to total cleaning • Minor surface consolidations can be done on stone cracks 33 33

    FLOORS The conservation needsrequire that all the tiles used should be uniform and shall blend with the architecture of the building. The choice will be made by the relevant appropriate authority through the nodal agency proposed. PAINTING DEFECTS Paints Peeling off due to improper surface preparation • Whitewashing to be done annually In the month of October. In utility areas i.e. Toilets, kitchen • Repairs of plaster should be done with lime mortar, if necessary with the help of organic polymer binder. 34

    TIMBER Damaged timber tobe removed and replaced with matching recycled timber General guidelines • Anti-termite and wood preservative treatment, varnish and paint system - to be applied once a year. • Flat oil paint/lead based paint to be applied to the exterior wood. METALS • All metal surfaces should be painted with metal paints once in three years. • Use of mild steel should be avoided in this building for corrosion instead non-ferrous plastic metals are to be used like stainless steel, galvanised iron, copper. 35

    36 ELECTRICAL SYSTEM • Restorationand checking of earth-pits at substation and preventing leakages in the substation. • Correcting the defects in the L.T. distribution panels. • Replacing old wiring. It is strongly recommended that instead of doing a patchwork, total electrical system for the whole building should be designed and implemented. • Open wiring in corridors should be placed in box type channel throughout the building. • Optionally, installation of capacitor-bank and Power Factor Monitoring Equipment to improve P.F. of installation and save energy. • Following tests for the installations safety should be carried out at the earliest: a) Insulation resistance test b) Earth Continuity test 36
  • 37.
    WATER SUPPLY SYSTEM •The whole of the water supply to the plumbing apparatus is required to be redesigned and the distribution should be done through 2 centralised overhead tanks and a well designed terrace loop system using non corrosive pipes having ultra violet rays stabilising properties. • Internal water supply: Internal water supply inside the toilets also need total restoration as the pipes used for feeding the apparatuses are very old. The piping should be concealed as exposed piping is always subject to tempering and damage. The internal plumbing should be either of 99.9% percent pure copper pipes of 0.9 mm thickness and of bendable quality, minimising joints and avoiding the tempering. • Vertical external drainage system: Vent, rainwater pipes etc. are also very old and needs replacements in some cases. 37 37
  • 38.
    38 PLUMBING AND SANITATION •The present plumbing pattern is not only unorganised, but is also visually disturbing as exposed pipes are seen in the main circulation corridors and on the main facade of the building. Some pipes are seen to be running along the floor on the second floor where the toilets are situated in the centre of space. • Detailed plumbing plan has to be prepared for the building with a thorough mapping of all the water outlets, rainwater discharge pipes and other plumbing fixtures. It is observed that the position of the water tanks all along the flat areas of the terrace causes excess dead load, hence showing distress in the timber joists on the second floor. These should ideally be accommodated within one overhead tank fulfilling the water requirements for the entire building. 38
