8.0 PROBLEM ENCOUNTRED AND SUGGESTED SOLUTION
Every structure's demolition procedure comprises taking down buildings to clear the area as
well as small operations such as rehabilitation or removing some components of the structure.
There are numerous challenges that may arise during the demolition process that are pretty
like those that may arise during any other form of building work. Therefore, in this demolition
project of Masjid Habib Al-Attas, the were problems encountered during the demolition proses.
Without a doubt both design team and the contract that is ‘Perniagaan Xmatrix’ able to find
the solution in time and successfully completed the demolition project within the project
timeline.

8.1 Problem and Solution 1.
Problem 1: Noise and Air Pollution.

The surrounding location of Masjib Habib Al-Attas was located near shop lots including
restaurants and hotels. In addition, the demolition of the building generates noise and air
pollution in the surrounding structures. If there are no preventative measures are made to
address this issue, noise pollution may cause persons in the surrounding area to feel
significant levels of stress or high blood pressure. Meanwhile, air pollution may have an impact
on the health of those living nearby. As a result, the contractor and design team took a few
steps to resolve this issue to avoid any disagreements or disputes with the surrounding shop
owners.
Solution 1: Use Suitable Equipment and Tools, Use Water Sprays or Sprinklers.

The design team decided to employ appropriate techniques and equipment that emit
a reduced spectrum of noise to reduce noise pollution. For example, for specific areas of the
construction, the use of large plant and machinery is minimized, and instruments such as a
sledgehammer are used. This could prevent surrounding residents from being overly disturbed
by the noise generated during the demolition process. Meanwhile, in terms of air pollution, the
design team chose to employ water sprays or sprinklers to regulate and prevent dust from
spreading throughout the demolition process. This could reduce the number of pollutants
emitted by the individuals living nearby.

8.2 Problem and Solution 2.

Problem 2: Disturbance to Nearby Road.

Generally, Masjid Habib Al-Attas was located by the roadside of Jalan Tun Abdul
Razak. As a result, the demolition process is a nuisance on the road and may cause damage
to passing vehicles or, in the worst-case scenario, death due to mishaps if safety procedures
are not taken. As a result, the design team must devise a better plan to avoid traffic congestion
and incidents caused by the mosque's deconstruction. This may result in a faster completion
of the demolition works.

Solution 2: Demolished Part by Part, Uses Netting and Hoarding.

The design team chose to dismantle the mosque in stages. For example, the mosque's
areas closest to the road will be demolished during the day when the road has the fewest
traffic passing by. This solution was made to ensure that the traffic on the road near the
mosque is not affected, especially during peak hours. This is done to keep the route from
becoming overcrowded and causing any conflict or disagreement with the locals. Aside from
that, the design team chose to surround the demolition area with netting and hoarding. This is
to prevent debris from flying out of the site and causing damage to vehicles going by. In the
worst-case scenario, the damage could result in incidents and death. As a result, utilizing
netting and hoarding helps ensure that all waste and debris is contained within the site.

Figure 13: Problem 2.

8.3 Problem and Solution 3.
Problem 3: Raining Season.
The demolition of the Masjid Habib Al-Attas takes place during Johor's rainy season. As a
result of the rain, the demolition process has been delayed several times. This is because if
the demolition process is continued even when it is pouring, it may damage the earth and the
mosque's foundation. Due to raining, it contributes to the condition of soil to be moist. Because
there is store lots near the mosque, the demolition operation may have an impact on their
foundation if it is extended because it may create vibration to neighboring structures.
Solution 3: Applying for Extension of Time (E.O.T).
Because there could be implications if the demolition process continued during the rainy
season, the contractor requested E.O.T to postpone the destruction. Even if it means a later
completion date for the demolition work, it is preferable to cause serious damage to
neighboring structures, which could lead to a dispute or worse, a lawsuit.

Table 3: Comparison Between Case Study 1 (Office Building) and Case Study 2 (Masjid).

25 | P a g e

An examination and comparison of two or more items or ideas is defined as a
comparative study. Comparative studies are conducted to demonstrate the capacity to
investigate, compare, and contrast subjects or concepts. A comparative research
demonstrates how two subjects are similar or how two subjects differ. Table … above shows
the comparison between Case Study 1 (Office Building) and Case Study 2 (Masjid) that we
conclude based on the parties involved in the demolition project, the types of demolition,
methods of construction, demolition procedures, material used, and problems occurred during
the demolition and its solution for both case study.

First and foremost, by referring to the table above we can see that Case Study 1 (Office
Building) took much shorter period to complete within 18 months with the total of
RM13,517,283.00 to complete the demolition project. Compared to Case Study 2 (Masjid)
took a longer completion period of 27 months in total with the project cost of RM8,500,000.00.
Generally, in this case if we compared Case Study 1 (Office Building) and Case Study 2
(Masjid) side by side, we could conclude that demolition project that took a shorter completion
period would cost substantially more than the project that took a longer completion period.

Next, if we look at the type of demolition used for Case Study 1 (Office Building) that
used the partial demolition works that where only some specifies section of the building is
being demolished. Compared to Case Study 2 (Masjid), hand demolition and pusher arm
demolition are two types of demolition used in this demolition project to fully take down the
whole building. Moreover, for Case Study 1 (Office Building) the demolition works take place
for existing ceiling finishes, doors, windows, partitions, and including make good and
maintaining works. On the other hand, for Case Study 2 (Masjid) the demolition works take
place for existing toilet fittings, demolition of brick wall, demolition of window and door,
demolition of finishes and other elements, including make good and maintaining works.

Furthermore, as stated in the table above the planning workflow for the methods used
to demolished both project of Case Study 1 (Office Building) and Case Study 2 (Masjid) is the
same. Firstly, as survey was conducted to examine all the elements. For example, examine
the wall and any electrical equipment that are connected to it before commencing any works
Secondly, the design team will plan the demolition process and then mark the part of the
elements that need to be demolished. Next, they will continue to demolish the required parts.
For, example demolished the toilet, doors, windows, ceilings, and brick walls. Finally, they will
make good, maintain, seal off with protection, cleaning the existing components to its
condition.

26 | P a g e

Next, we will be looking into the procedures that were used in both Case Study 1 (Office
Building) and Case Study 2 (Masjid) by referring to the table above. The procedures that take
place in Case Study 1 (Office Building) was divided in three stages that was pre-demolition
phase, demolition phase and post-demolition phase. On the contrary, Case Study 2 (Masjid)
begins with survey of the building for demolition, followed by the removal of hazardous
materials and preparation of the demolition plan. Finally, they ended it with safe measures that
need to be taken while performing the demolition works.

Moreover, in demolition and alterations works material used during the demolition
procedures would be one of the crucial components that need to be considered. Table above
shown that in Case Study 1 (Office Building), the materials used in the demolition works
consist of a wide range of tools and equipment such as scaffolding, Hilti breakers, angle
grinders, sledgehammers and many more. Meanwhile, for Case Study 2 (Masjid) the
equipment and tools used was mattock, angle grinder, crowbar, tower crane and excavator.
The wide range of equipment and tools used enough to answer why the cost of project for
Case Study 1 (Office Building) was higher-priced than Case Study 2 (Masjid).

Furthermore, based on the table above we compared both case study’s problem
occurred during the demolition project take place and the solutions taken to resolves the
following problems. Case Study 1 (Office Building) shows that there are four (4) problems that
had resolved by the design team during the demolition project that was firstly, there are taints
spotted in the development of drawing. In result, the decision made to resolve the problem
was before the work began, every drawing must be thoroughly revised. Secondly, there are
breakdown of some unacceptable demolition segment detected in the demolition project.
Using a satisfactory and adequate number of supports was used to prevent the demolition
segment to breakdown. Thirdly, there was a high risk of injuries that can happened on site.
For this reason, a number of security and safeguards was place nearby the site. Next,
restriction of sources would had disturbed the demolition project to run smoothly. In result, the
design team had analyzed thoroughly the building layout, structure of design and manage the
material.

Lastly, Case Study 2 (Masjid) had encountered a fewer problem if we compared to
Case Study 1 (Office Building). A total of three (3) problems and solutions was made during
the demolition proses. First, there was noise and pollution that can affect the surrounding for
the demolition site. To resolve the problem the design team decides to use suitable equipment
and tools, use water sprays or sprinklers to minimize the damage that can happened in the
surrounding. Next, the demolition works would cause a disturbance to nearby road and by
demolishing the structure parts by parts, use netting and hoarding during the demolition work

take place would avoid a further disturbance to nearby road. Finally, the demolition of Case
Study 2 (Masjid) take place during raining season. In result the design team had come into a
decision to apply for the Extension of Time (E.O.T) to ensure the demolition work run smoothly.

10.0 CONCLUSION
In a nutshell, demolition works are needed in Malaysia. In both case study, we can see the
operation and procedures of demolition works, types and methods of construction that being
used, demolition procedures, material and equipment used, construction process and safety
procedures that need to apply. Not to forget, we also explained about the problems that
occurred during the demolition works and steps that need to be taken care of to resolve the
problems.

Plus, both client in this project is government and there are also other teams that
involved too such as architects, and planning team. All the parties involved are responsible for
taking care and commencing the demolition works in accordance with all the regulations and
procedures. A skilled person or a person with a knowledge in demolition works are needed to
ensure that all of the demolition process runs well from the pre-demolition phase until the end
of the post-demolition phase.

Both case studies have shown us that there are differences in every demolition works.
Not all demolitions works are the same. Each of them had been chosen because of different
material used, problems encountered and many more. Plus, the size of work differs too.
Finally, demolition works bring benefit in helping Malaysia to progress towards achieving a
better status.
