ABSTRACT

Bali has been well-known as a tourism place; therefore the development of infrastructures including building projects

in this area has also increased significantly.

Constructing a building project particularly in the southern part of Bali, which is

recognized as a heavy congested area of tourism activities, is likely to face difficulties and risks related to the access and the

delivery of materials and equipment to the project location, as well as problems dealing with social, political and regulations.

This paper aims to evaluate and assess risk factors that impact on the construction of building projects in Bali. A

questionnaire survey was developed based on extensive literature review. The survey involved 20 participants that were

selected based on purposive sampling method. It covered contractors, clients (project owners), and consultants those have

experienced on constructing building projects located in this particular area. The collected data was analysed using

descriptive statistic to identify and calculate the likelihood and consequences of risks. Mitigation actions were formulated

after classifying risk in terms of risk acceptability. The findings indicates that the identified risks covers three negligible risks,

six acceptable risks, twelve undesirable risks and eight unacceptable risks. Risk mitigation should be taken to address the

major risks (undesirable and unacceptable risks) that mainly rooted from four sources, i.e. Social, political and regulations;

environm ent and nature; finance; and technical of the project.

Keywords: risk assessment, building projects, likelihood, consequences, major risks

1. INTRODUCTION

The economic development in the southern part of Bali has grown-up rapidly, which is dominated by tourism

business. It can be seen by the increasing numbers of infrastructure and building projects such as hotels that particularly

located in Badung regency. This situation indicates that construction business in this area is well-promised. Badung regency

is known as a congested area thus it generates challenges when constructing a building in this location. For instance, heavy

traffic jam can impact on the accessibility to the project location, difficulties to load materials and equipm ent, the noise and

pollutant impact on the environment and other technical risks during the constructions period. Contractors should be able to

manage these risks, so, they can achieve the project’s objectives, i.e.: to meet time, cost and quality as being planned.

Practically, realizing these three objectives often becom es a critical issue.

There are many factors that influence the success of a project completion. Risks that particularly related to the

construction of the project are one of the factors that should be identified in order to minimize the consequences that likely

impact on the project completion. Therefore, identification of risks that likely occurred during the construction phase is an

important early stage prior formulating strategies for managing them. This paper aims to identify and assess risk factors

related to construction of building projects in Bali. The identification of risk factors was conducted based on an extensive

literature review. Subsequently, the identified risks were examined through a questionnaire survey. It involved 20 participants

(contractors, consultants, and clients) those experienced on constructing building projects in the area of Badung Regency

(i.e.: Seminyak, Legian, Kuta, and Tuban). This paper begins with a review on risk identification in construction industry and

risk assessment.

2. RISKS FACTORS IN CONSTRUCTION INDUSTRY

Construction industry has often faced the negative effects of change that lead to the failures of many projects to

achieve the deadline, cost and quality as being set. Risk occurs due to uncertainty that lead to the possibility of adverse

events. However, Al-Shibly

,

et al [1] argue that if it was practiced in the correct way, risk can becom e a positive key factor for

the company

.

Smith

,

et al [2] suggest that employing the principles of risk management will enable engineers to improve the

management of this change effectively.

3. RISK ASSESSMENT

The first step of risk assessment is by determining the degree of likelihood and consequence of each risk factor. It

can be represented by the frequency of mode in descriptive statistics. Multiplication between the mode score of likelihood

and consequence will result the degree of risk or called as risk index (RI). The value of RI indicates the level of risk

acceptability. Godfrey [7] provides a guidance for classifying risk acceptability level based on the value of RI, as depicted in

Table 2.

Accordingly, risk assessment can be formulated as [7]:

RI = P x I

where:

RI –

the degree of risk (Risk Index)

P –

Probability (or likelihood) of occurrence of a risk.

I –

the consequence or perceived impact on a project

which is associated with the degree of risk. Norman and Flanagan[4] suggest four methods for risk mitigation that includes

risk retention, risk reduction, risk transfer and risk avoidance. Based on the degree of risk categorised by Godfrey [7],

acceptable and negligible risk are indicated as low risks, so, risk retention can be taken. Meanwhile, unacceptable and

undesirable risks have higher degree of risk, therefore proper mitigation actions should be focused on these types of risk.

Finally, risk ownership must be defined to specify the parties that responsible and control the risks[4].

4. METHODS

The identified risk factors from the literature were used to develop a questionnaire that consists of 29 questions that

were derived from 5 (five) sources of risk. The questionnaire was distributed to 20 participants, involved contractors,

consultants and clients those experience on constructing building projects in the area Badung Regency (i.e.: Seminyak,

Legian, Kuta, and Tuban). The questionnaire used Likert scale format for measuring respondents’ opinion related to risk

likelihood (probability) and risk consequence. The scale used for measuring risk likelihood is: 1(never), 2(rarely),

3(sometimes),

4(often), 5(very often); while, for measuring consequence is: 1(very low), 2(low); 3(moderate), 4(high), 5(very

high). The retrieved data was tabulated based on its frequencies (mode). The mode score of likelihood and consequence

was multiplied in order to define the degree of risk and to classify the level of risk acceptability. Then, formulation of risk

mitigation was focussed on major risks (undesirable and unacceptable), which followed by specifying of risk ownership.

5. RESULTS AND DISCUSSION

The responses retrieved from 20 participants of the questionaire survey was tabulated. Reliability and validity test was

conducted and confirm ed that the instrument (questionaire) is reliable and valid. This was indicated by the values of

Cronbach’s alpha that above 0.70 and the calculated ”r” that above 0.444 (r table)[11]. Subsequently, the data was analyzed

using descriptive statistics (employed SPSS version 19) to determine the mode (frequency) of ”likelyhood” and

”consequences”. Risk index (RI) was obtained by multiplying them. The result is presented in

Table

3

. This table also indicates risk acceptability that classified into: three negligible risks, six acceptable risks,

twelve undesirable risks and eight unacceptable risks. Risk mitigation was focused on major risks that cover undesirable and

unacceptable risks.

6. CONCLUSION

The related parties (contractors, consultants and project owners) those will be involved in constructing a building

project located in a congested area as like as in the south of Bali, should consider these risk factors. The suggested actions

need to be taken by the risk owner for mitigating the adverse impacts on project completion, which particularly embedded

from four sources, i.e.: Social, Political and regulations; Environment and Nature; and Technical of the project.
