PROCEDURES OF INTERVENTION


5/27

PROCEDURE OF INTERVENTIONMACRO(ADOPTED FROM BURRA CHARTER 1999)

Understand Significance

1. Identify building / monument / place to be conserved and its associations

- secure it, make it safe

2. Gather & record information about building / monument / place, sufficient

to understand significance

- documentary, oral & physical

3. Assess significance

4. Prepare a statement of significance


6/27


Develop Policy

5. Identify obligations arising from significance

- what tasks to be taken by stakeholders

6. Gather information about other factors affecting the future of building /monument / place

- anticipate the possible risks / developments

- needs, resources, external factors, physical condition

7. Develop policy

- identify & consider options- test their impacts on significance

8. Prepare a statement of policy


7/27


Manage

9. Manage building / monument / place in accordance with policy

- develop strategies

- implement strategies through a management plan

- record prior to any change

10. Monitor & review

- flexibility

- priority

9/27

Main Principles of Building Conservation1. Minimise interventions / disturbances

- to structure & fabric

2. Undertake scientific research & lab testing

- materials, structural integrity

3. Documentation of conservation efforts

- report, method statement, illustrations

- for future reference, to be kept safe

4. Application of methods and techniques

- of proven efficacy

- improve condition but not to disturb authenticity

PROCEDURE OF INTERVENTIONMICRO(ADOPTED FROM THE FRAMEWORK OF HISTORICAL BUILDING CONSERVATION BY PROF. Dr. A GHAFAR AHMAD, USM)


10/27

Work Programme of Building Conservation1. Preliminary research

- on reports & records of history, owners, occupants, architecture etc

- interviews with relevant parties

- to produce report for owners further actions: appoint steering committee &

consultants



11/27

Work Programme of Building Conservation2. Dilapidation survey

- materials, structural integrity etc

- multi-disciplinary, extensive, sometimes scientific- defects, causes, how to rectify

- measured drawings, illustrations



12/27

Work Programme of Building Conservation3. Preparation of tender document

- involvement of owner, steering committee and quantity surveyor to

scrutinise dilapidation survey- Bill of Quantity by QS

- other consultants to advise QS on scope of work, suitability of conservation

methods etc

- cost estimate could be reached



13/27

Work Programme of Building Conservation4. Building conservation works

- by experienced building conservation contractor

- he should have his own conservator as advisor & to liaise with consultants

- conservator to produce record, method statement, scientific report and lab

testing report

- regular site meeting

- contractor to follow principles of conservation

- to use method in Historical Architectural Building Survey (HABS) for

systematic recording of building before, during & after conservation effort

- HABS: 1 m2 grid system of surface recording



14/27

Work Programme of Building Conservation5. Heritage management

- periodical maintenance after conservation effort completes

- to consider other physical, social & economic factors surrounding building- to minimise impact from exposure to humans & environment

- through good management plan that involves all stake holders

DEGREES OF INTERVENTION


17/27

1. PREVENTION OF DETERIORATION

Control environment of cultural property

- prevent agents of decay/damage from becoming active

- need regular inspection

Control of internal humidity, temperature, light, measures to prevent fire, arson,

theft, vandalism, pollution, moisture

Reduction of atmospheric pollutants, noise, traffic vibration

Prevention of uneven ground settlements, rising damp


18/27

2. PRESERVATION OF EXISTING STATE

To keep cultural property in existing state

Repairs if necessary to prevent further decay

To prevent damage caused by water, chemical agents, pests, micro-organisms

Example:

damage on roof tiles water leakage into building

repair roof to prevent decay of other materials


19/27

3. CONSOLIDATION OF FABRIC

Physical addition or application into actual fabric of cultural property, ensure

continued durability / structural integrity

Supportive materials, injection of adhesive to secure detached material

Consolidation of existing materials to preserve strength of structural elements

must respect integrity of structural system and form

Modern approach over traditional skills and materials only if necessary, at

proper scale

Continuous repair and restoration for short-lived materials (mud, unbaked bricks,

wood)

Kinabalu Park, Malaysia


21/27

4. RESTORATION

To revive original concept or legibility of object

Must be based on original materials, archaeological evidence, original design,

authentic documents

Replacement to integrate with the whole, but still distinguishable from the old

Respect periodic contributions as historic documents

Revealing of underlying state of superimposed work of different periods must be

justified


22/27

5. REHABILITATION

To keep building in use with a certain degree of adaptive alteration

Original use is the best

Examples:

- shophouses to boutique hotels & eateries- Asian Heritage Row


23/27

6. RECONSTRUCTION

For buildings damaged by fire, earthquake, war, floods

Done based on accurate documentation and evidence

Examples:

- Candi Borobudur- Part of Fort Cornwallis


24/27

7. RELOCATION

Buildings moved to new site due to disturbance at

existing site

- floods, erosion, development

Examples:

- Masjid Kg. Laut- Rumah Penghulu Abu Seman

bldg 2) how to contrl visitors coming in 3) how to have progressive/periodical

maintenance (to produce manual) 4) how to make bldg adaptable to current +future devlpmt
