Construction industry inundeniably is the mosthazardous industry inMalaysia.

SOCSO report (2000)

Fatality rate more than 3times of all workplaces(3.3% compared to all

workplaces of 1.1%).

The safety cost is one of the factors affecting the safety

standard at construction sites.

It is a duty of all employers to provide safety andhealth environment at work place as highlighted in theOccupational Safety and Health Act 1994 Section 15

(1) and (2).

1

The assessment of safety cost for scaffolding thatmeet safety requirements need to be addressed inorder for contractors to provide good safety practiceat construction site.

2

However, most of the contractors are unawareabout how much the safety progress in scaffoldingcost and how it affects the project budget. Lack ofknowledge about cost of safety and its portion ofthe project budget may have significant impact onthe profit margin and may increase the risk offinancial difficulties.

Focused on safety cost inscaffolding works specific in

building construction.

The study will be limitedto the site work ofprovide scaffoldingworks in Johor andKuala Lumpur.

INFORMATION AND DATA COLLECTION

DOCUMENTSSTUDY

Malaysian enacted acts, regulations, books and journals, andinterviews with scaffolding instructor from CIDB in order toidentify the safety and health requirements in the scaffoldingworks.

Interview was also done with DOSH Federal Territorys Officer

to verify the requirements compiled.

PILOT STUDY

In order to get the appropriate proportion of cost,questionnaires have been distributed to five construction

projects with variety project cost. The results obtained in thispreliminary survey were used to determine the mostappropriate percentage of cost choices. The finalizedquestionnaire is then used to execute the survey.

INFORMATION AND DATA COLLECTION

QUESTIONNAIRES

Interviews using structured questions to identifythe safety cost portion of project budget based onrespondents experiences. T

hey were required to determine the cost of every

elements of safety requirements in scaffoldingworks by choosing the most appropriate answer offour ranging cost given in the questionnaire,described as 1) 0 0.2%; 2) 0.2 0.5%; 3) 0.5 1 %;and 4) more than 1%.

Majority of respondents agreed that

safety cost allocated in thoserequirements were not more than 0.2%

for each elements.

- From the figure,

all respondents agreedthat the cost of theserequirements: DesignatedPerson; Documentation;Safety and HealthCommittee; Inspection /Investigation; andPersonal ProtectiveEquipment (PPE); and alltheir breakdowns werenot more than 0.2% foreach elements.

- The cost for theserequirements: Design ofScaffolding; ScaffoldingWorks; and Signage, Toolsand Equipments; and theirentire breakdowns were

seemed to be varies fromrange 0 - 0.2%, 0 - 0.5%and more than 1%.

- However, majority ofrespondents hasresponded that the safetycost allocated in thoserequirements were not

more than 0.2% for eachelements.

IVE1

- The safety and healthrequirements inscaffolding works have

been identified.- The requirements can becategorized into 8 groupswhere each groupconsists of breakdown

elements. The safety costof scaffolding works isidentified based on thesebreakdowns.

BJECT

IVE2

- From the survey andanalysis, most of therequirements wereallocated not more than0.2%, where several of them

allocated not more than0.5% and more than 1%.

- The reason of this to occuris because the contractorsdo not keep the actual cost

for erecting scaffolding forall projects. In addition, allprojects do not keepapportion of safety cost forerecting scaffolding.
