i) provide temporary protection on the site to ensure
that the existing building elements and spontaneous
plants were not further damaged during construction.
(See Figure 4 & 5)

ii) use appropriate construction methods and material
that will retain the authenticity of the building in
terms of design, materials, workmanship and setting.
Replacements should be as close as possible to the
original materials.
iii) consider the conservation principal of minimum
intervention, even though it is hardly appropriate for
a re-building project. In order to upgrade the
facilities, it was necessary to comply with the latest
services and law requirement such as fire fighting
equipment, accessibility and facilities for disabled
people, mechanical and electrical system, sewerage
and piping facilities, stage facilities etc.
2.3 Construction Period
The initial work of the building reinstatement started in August,
2001 when the building teams were appointed. The entire
project took almost a year (initial concept to hand over) and the
construction period was 4 months and 3 weeks (handing over in
August 2002). The entire project cost was estimated of about
Ringgit Malaysia 13.8 million. The building was officially
launched for its second time on 20 th August 2002 by the
Malaysia Deputy Prime Minister, Datuk Seri Abdullah Ahmad
Badawi.
2.4 Construction Stages
a) First Stage - Structural Repair, Crack Repair & New
Roof Design
The damaged structural elements such as column and beams
were repaired to their original state. The structural repair for all
the concrete elements was done carefully in order to retain the
authenticity of the original design. The methods used were not
only to regain the structural strength as designed and verified
by the structure engineers, but also to regain the original
appearance of the elements.
After hacking and repairing the steel reinforcement bar of the
concrete and beams (refer to Figure 6), a few layers of bonding
agent called ‘Nittobond EP’ were placed to cover the exposed
structure (refer to Figure 7). Then the formwork was prepared
from layers of timbers line up to produce a textured surface as
to its original design. The ‘Renderoc LA Concrete’ was filled
up and hardened until the required strength about 60KN was
achieved. Once concrete hardening, formworks were removed
and surfaces were refined.

Ninety percent of the existing concrete elements surfaces were
covered with soot mark and they required to be cleaned.
Appropriate methods of cleaning were used. At the beginning,
water jetting system was used to the entire surfaces (See Figure
8). It was found that the soot mark were embedded into the
surfaces and difficult to remove especially at certain elements
and remote area such as concrete fins, slab soffits, staircases
