Safety plays an important role in almost all the aspect of Civil Engineering. Safety procedures in construction site are well established, but the culture of a project site and workers attitudes often result in procedures not being followed to achieve the best safety outcome. The importance of safety as a cost controlling measure is often overlooked by

vi owners and contractors. As a means of reducing the risks associated with construction, safety can significantly impact the overall cost. A dedicated commitment to safety by both the owner and contractor helps to ensure the success of the project and can impact the bottomline considerably.

The present study focuses on the effectiveness of safety management in construction site with a help of a questionnaire. The questionnaire was designed based on the following factors, namely project nature, historic factors, organizational structure, management measures, individual involvement, economic investment, labour management relation, causes and remedy for accident. As an initial step the pilot survey with the help of questionnaire was conducted with four construction personnel.

The questionnaire was modified based on the feedback of the pilot survey. The survey was conducted with ninety construction companies in and around Chennai and other major cities in Tamilnadu. Fundamental statistical analysis was made with the surveyed questionnaire and the results were reported. A booklet of minimum safety precautions to be followed in construction sites has been prepared based on the available codes, guidelines and distributed to construction companies.

CHAPTER 1

INTRODUCTION 1.1 GENERAL

The significance of the construction industry to the economic and social life of the country is noteworthy. The industry needs much investment and involves various types of stakeholders and participants. From the point of view of safety the conditions normally encountered in the construction industry does not lend themselves to the degree of control, possible in other industries where more stable conditions are generally obtained. The construction industry is usually very large, complex, and different from other industries. Hence it is prone to numerous health hazards.

1.2 SAFETY

An accident can be defined as an “Unplanned, Undesired, Unexpected and Uncontrolled event in which the action or reaction of an object, substance, person, or radiation results in personal injury or the probability thereof in the course of the employment”. Hence there is a need for safety measures which can be defined as the absence of danger at work, which is possible by elimination of hazards that create the danger. More practically, “A thing is provisionally categorized as safe if its risks are deemed known and in the light of that knowledge, judge to be acceptable”.

1.3 IMPORTANCE OF SAFETY IN CONSTRUCTION

The construction industry has traditionally been considered as a hazardous occupation, due to the high incidence of occupational injuries and fatal accidents. The number of fatal occupational accidents in construction all over the world is not easy to quantify, as information on this issue is not available for most countries. The outlay on construction in successive five year plans of India has been in the range of 36% to 50%.

2 The construction industry, employing the largest labour force, has accounted for about 11% of all occupational injuries and 20% deaths resulting from occupational accidents. International Labour Organisation (ILO) has estimated that at least 60,000 fatalities occur at construction sites around the world every year. This means that one fatal accident occurs approximately every ten minutes in this sector. Most of these accidents are created due to unsafe behaviour and unsafe conditions.

1.4 NEED FOR SAFETY MANAGEMENT

The construction industry has some special features which have a direct bearing on the accident potential. In this trade the pattern of work is ever changing. The operations and physical circumstances change constantly unlike in the factories where the process, the method and the operations are generally repetive. Timings and schedules vary considerably from place to place. The most important changing factor is the change of men themselves. The inherent nature of construction jobs combined with the above factors make this industry as one with accident risks. Safety is a critical item on all construction projects for multiple reasons including protecting the welfare of employees, providing a safe work environment and controlling construction costs. However, the importance of safety as a cost controlling measure is often overlooked by owners and contractors. As a means of reducing the risks associated with construction, safety can significantly impact the overall cost. A dedicated commitment to safety by both the owner and contractor helps to ensure the success of the project and can impact the bottom-line considerably.

Safety precautions when properly enforced, it will help in minimising accidental injuries in the various operations involved in different types of construction works. Adoption of pre-determined safety measures in each of these operations will not only prevent or reduce accidents but also promote quicker and risk- free working of labourers resulting in increased efficiency along with reduced costs of constructions.

3 1.5 RESPONSIBILITY OF SAFETY

Modern construction management cannot expect to discover the single, allpurpose programs that will meet builder needs, mounting levels of concern by contractors facing tough new laws and spiraling costs. Yet no contractor may expect to enjoy the fruits of improved job safety without a firm, detailed, written statement of objectives, and carefully spelled out definitions of the ways and the means for achieving this improvement. No such policy can curb lost time accidents, hold down the compensation, or enhance worker attitudes, and performance without being specifically adapted to each contractorâ&#x20AC;&#x2122;s own attitudes and own area of work.

There are contracts of many trade involved in a construction project. Hence the main responsibilities for safety and health are upon the principal contractor, but that each employer is responsible for applying measures relating to workers under their own control. The construction industry demands the attention of everyone involved. It requires the government, trade unions, sectorâ&#x20AC;&#x2122;s associations, developers, architects, engineers, contractors, subcontractors and workers to play their role. All the members involved must work together to create a safe and healthy workplace for all.

To avoid the high losses caused by injuries, contractors are required to implement various safety procedures like fall protection, respiratory protection, confined space entry, competent person and other programs that control the causes of injuries. If the contractor is successful in preventing these injuries, overhead cost of insurance and hidden costs of accidents are significantly reduced, bringing more profit to the contractor. Hidden costs of an accident are four to ten times the actual costs of the claim and account for items such as employee replacement costs, loss of use, increased insurance costs, damaged product, etc. The direct cost of accidents only includes items such as doctorâ&#x20AC;&#x2122;s consultation fee, ambulance, as well as medicine costs.

4 1.6 SAFETY CLAUSES IN CONTRACT DOCUMENTS

All contract documents signed by the owner and contractor contains various safety clauses wherein the contractor is obligated to make provisions for the safety of men and structures, and the consequences for failure to do so. The contractor is already mandated by law to comply with state and national regulations. The owner has to demand that the contractor document and implement the proper safety programs that will protect employees working on the job site. Owners sometimes hesitate and feel that they are interfering with the contractor’s way of doing business if they express concerns over safety at a jobsite. In reality, owners have the absolute right to mandate that a good quality safety program be an important part of the selected contractor’s culture. The contract documents are an effective tool in conveying the owner’s safety requirements to the contractor. In addition, there are many benefits to prequalifying a contractor by comparing the firm’s safety record and other company statistics with the competition. A contractor with a good safety program is often a better choice even if the initial bid package is higher than the firm’s competitors. Poor safety compliance increases the owner’s risks and often inflates the final costs of a completed contract, and it is the final cost that need to be considered into this decision making process.

1.7 LEGAL REQUIREMENTS

Safety at construction sites is covered under many legal enactments. The Building and other Construction Workers Act, 1996 is a comprehensive piece of legislation that provides for registration of contractors, setting up of construction labour boards, regulation of working conditions, health and safety of construction workers etc. many other statutes are applicable to construction sites.

The repair workshops of contractors or those attached to construction sites are covered under the Factories Act, 1948. Quarries operated are covered under Mines Act, 1952. Vehicles plying to and fro at construction sites are subjected to Motor Vehicles Act, 1951. A contractor’s office is covered under the Shops and Commercial

5 establishment Act, 1962. The Contract labour Act, 1971, regulates the employment and working conditions of contractors labour. The immigrant labour is regulated under the Inter-State migrant Workers Act, 1971. The Workmenâ&#x20AC;&#x2122;s Compensation Act, 1923 is applicable to all construction sites throughout the country. It makes the employer liable to pay compensation and provide medical care to workers who meet with accident out of or in the course of employment. Child labour and maternity is dealt with under separate statutes.

Thus comprehensive safety legislation for the construction industry is yet to be framed. However, over the years, through practice as well as the decision handed down by various courts a set of ground rules describing safety practices that must be followed at construction sites have emerged.

There are four sources of legal requirements regarding safety as applicable to construction sites and construction industries. They are 1. Standards laid down by Bureau of Indian Standards. 2. Statutory provisions framed under various labour laws. 3. Contract conditions written into the contract document signed by the client and the contractor when the work is awarded. 4. Decisions, judgements and awards made by the judicial authorities from time to time.

1.8 SAFETY PROGRAMME

The safety programme of a construction organisation is a compact package which comprises a safety policy, safety department to implement the policy, and specially trained personnel to man it. Workers should be involved in the safety programme through bipartite safety committees and other participatory measures. Safety records, monitoring and training as well as periodic safety audit should be the essential aspects of such a programme. The general safety inspection program that has to be followed in construction site is shown in figure 1.1

1.9 SAFETY POLICY

An construction organisation which is concerned with establishing high standards of safety at work sites as well as throughout the organisation should have a safety policy which forms an integral part of the over all policy of the organisation. The safety policy comprises a statement of the organisations objective regarding safety of men in operation and at work sites. It also contains guidelines for action that will be taken at appropriate

7 levels to achieve the objectives. The safety policy will enjoy higher credibility and get better implemented if the safety reports reach the top management.

1.10 RESULTS OF AN ACCIDENT

Safety issues in construction injuries have a direct impact on the individuals involved in construction as well as on the work itself. Impacts include personal suffering of the injured worker, construction delays and productivity losses, higher insurance premiums that result from injuries, and the possible liability suits for all parties involved in the project. There are many other indirect impacts such as revenue losses on the part of the owner for late project delivery and reduced morale of the work force. The most frequent causes of injuries and deaths on construction sites are falls, being struck by an object, being caught in or between objects, electrocution, and others, such as toxic gases, drowning, and fire.

Generally, most companies follow established safety guidelines and policies that meet OSHA guidelines. However, most incidents and injuries on construction sites are a direct result of not adhering to the established safety procedures .Therefore, to ensure a successful safety program, three conditions must exist: •

Management commitment and leadership,

•

Safe working conditions, and

•

Safe work habits by all employees.

Some of the risks that are caused due to accidents both to owners and to contractors are listed below: •

Employee injuries and fatalities

•

Cost and time over-run

•

Damage to property

•

Unidentified repairs

•

Contract extensions

•

Bad publicity caused by incidents

•

Increased insurance costs.

8 Many of the research efforts in construction safety have been focused on safety management. These efforts have identified a variety of ways that supervisors and managers of construction companies can impact the safety performance on a construction project. For instance, as early as in1931Heinrich suggested that unsafe acts are the cause of a high percentage of accidents. His study found that 88% of all accidents were caused by people, while10% of accidents were attributed to unsafe conditions. Heinrich is the first to state that incidents are symptoms of a lack of management commitment to safety, and that 98% of accidents are preventable by management.Komakiin1986 reemphasized Heinrichs theory and suggested monitoring and providing feed back as attributes of effective management .Komaki added that the performance of management might affect workers performance and attitudes. Similarly, many studies have concluded that management’s commitment is a precursor to a successful safety program.

Furthermore, one study showed that there is no clear understanding or uniform agreement among designers/owners, contractors, and subcontractors safety roles at a construction site .Despite the fact that several research reports have emphasized the role of management in reducing injuries and fatalities on construction sites, the injury and illness rate in Construction continues to be one of the highest across all industry sectors.

1.11 HEINRICH’S DOMINO THEORY

Heinrich in 1931postulated that accidents were caused by either an unsafe act, an unsafe condition, or both. Termed the `Domino’ theory, this work provided the first sequential theory of the accident causation process. Heinrich’s Domino model of accident causation, but it also brought the interaction between behaviour and conditions (situation) into sharper focus for the first time. In essence, the Domino theory asserted that accidents were caused by a sequence of events which encompassed five discrete stages. This began with a person’s heredity and environment which predisposed that person to behave in certain ways (such as being an accident prone person), and which led to either an unsafe act or the creation of an unsafe condition. In turn, either of these caused an accident which resulted in an injury. Heinrich asserted that each stage of the accident process was

9 analogous to a row of dominos in line with each other. If one fell, it automatically knocked down all the other dominos. Neutralising any one of the first four would prevent the fifth: the injury. Heinrich concluded that the key domino was that pertaining to unsafe acts. This perhaps reflected his findings that approximately 80% of accidents were triggered by unsafe acts, with the remaining 20% being caused by unsafe conditions (known as the 80:20 rule).Heinrich concluded that unsafe acts were caused by poor attitudes, a lack of knowledge and skill, physical unsuitability and an unsafe environment.

1.12 A MODEL OF SAFETY CULTURE

The interactive relationship between psychological, situational and behavioural factors is applicable to the accident causation chain at all levels of an organisation. It can be cogently argued that culture is viewed as an organisations prevailing safety culture. It reflects the dynamic inter-relationships between members perceptions about, and attitudes towards, organisational safety goals; members day-to-day goal-directed safety behaviour; and the presence and quality of organisational safety systems to support goaldirected behaviour. Consistent with the idea that culture can best be described as `the way we do things around here, the potency of this interactive model for analysing safety culture resides in the explicit recognition that the relative strength of each source may be different in any given situation. Similarly, the interactive influence of each source may not occur simultaneously. It may take time for a change in safety behaviour to exert an influence on and activate the relationship with the workflow system and work-related safety attitudes. Thinking of safety culture in these terms, therefore, provides an organising framework to assist in ongoing practical assessments and analyses as shown in figure 1.2. As such, given the appropriate measuring instruments, the relative influence of each component can be determined in any given situation, so allowing either highly focused remedial actions or forward planning to take place.

1.13 SAFETY BEHAVIOUR

For many years safety professionals have been aware that the majority of workplace accidents are triggered by unsafe behaviours, and that their control is one of the keys to successful accident prevention. However, many organisations, even those companies with low accident rates have been frustrated by their inability to control unsafe acts. Traditional approaches have tended to focus on raising the safety awareness of employees through publicity campaigns, safety training or disciplinary actions in an attempt to change both behaviour and attitudes. Although each of these approaches has its place, they are not in themselves efficient methods for managing change in either attitudes or unsafe behaviours.

The fact that changing behaviour leads to a change in attitudes enables management to focus attention on these behaviours, utilising techniques of goal setting and performance feedback, which result in significant and lasting improvements. The combination of goal-setting and performance feedback is a powerful management tool that has previously been used to good effect of improve a whole host of safety performance factors. By harnessing these motivational forces, behavioural safety approaches offer an effective alternative to traditional methods such as safety raining or

11 safety information campaigns, because they have to take into account the interrelationships between the organisation, the job and the individual. Thus behavioural safety initiatives meet the needs of both the individual and the organisation, while also positively impacting on safety culture.

Over many years, regardless of the industrial sector, scientific evaluations have typically found that implementing a behavioural safety initiative leads to: improved levels of safety performance, significant reductions in accident rates and associated costs. Improvements in co-operation, involvement and communication between management and the workforce improvements in safety climate ongoing improvements to safety management systems ownership of safety by the workforce enhanced acceptance of responsibility for safety better understandings of the relationship between safe behaviour and accidents. Clearly, these motivational techniques are central to the improvement of safety culture as they impact upon behaviour, perceptions and attitudes, and on safety management systems. Nonetheless, the degree to which they are successful is dependent upon many factors, such as the mechanisms used to set goals, how committed people are to reaching the goals, how confident people are in their abilities, whether or not safety goals conflict with other goals, the methods used to deliver feedback, the prevailing safety climate, and the current status of the safety management system.

1.14 SAFETY MANAGEMENT PLAN

A safety management plan is a collection of documents that outline how the principal contractor will manage health and safety for employees, sub-contractors, suppliers, visitors and the general public. It will cover all work activities that make up the job. The content and detail expected in a plan will depend on the size and complexity of the proposed work. A safety management plan must be prepared before the first soil is turned and should be subjected to an ongoing review as the project evolves. This approach leads to the most effective identification and control of the health and safety risks as the project progresses. The amount and type of documentation contained in a

12 safety management plan will vary depending on the size and complexity of the project. Much of a plan and its documentation will be transferable from project to project. At the planning stage of every project the principal contractor must review its safety management systems and generic Plan components against the new project requirements and tailor the plan to suit.

The principal contractor and/or his/her nominated technical and administrative officer is the most important for the preparation, submission and the administration of the plan ensuring compliance by employees, contractors, sub-contractors and their employees, suppliers, visitors and the general public. To ensure this occurs an individual or organization that is contracted to undertake construction work must appoint a “Responsible Officer”. In particular, the responsible officer ensures that safe systems of work are maintained and monitored and where necessary, documented.

The safety management plan must include the following features: •

Contain the Workplace Health & Safety Policy, the workers rehabilitation and compensation policy and other relevant policy documents.

•

Define the roles and responsibilities for key personnel, in particular the project manager, responsible officer and site supervisor as well as reference to the general duty of care all employees; contractors; sub-contractors and their employees; designers; manufacturers; suppliers; and installers.

•

Outline the training and minimum competency requirements for employees.

•

Establish a process for identification of hazards associated with each phase of the work and the assessment and control methodology to be used.

•

Contain copies of, or reference to, procedure documents relevant to the project activities and any safe work statements or site safety rules as applicable.

•

Indicate the site evacuation and emergency response procedures.

•

Outline the accident/incident notification, reporting, recording and investigation process.

•

Disciplinary procedures.

13 1.15 MANAGEMENT COMMITMENT & POLICIES

An effective safety management system will feature a series of policy documents that communicate how the system will be managed. These policy documents will cover key system elements, such as: •

Management Commitment

•

Workplace Health & Safety

•

Rehabilitation & Compensation

•

Responsibility & Accountability

•

Duties of all persons in the workplace

•

A statement requiring employees, contractors, sub contractors and visitors to comply with the safety management system

•

Provision of Resources

•

Consultation & Communication

•

Plant and equipment and associated certificates of competency

•

Training (induction, ongoing etc)

•

Hazardous materials

•

Hazard Management

•

Documentation & Document Control

•

Auditing

•

Accident/incident reporting and investigation

•

Discipline

•

System Maintenance & Improvement

Policy documents outline, in broad terms, the commitment to measurable goals and form the framework for the development of detailed procedures and safe work method statements. Policies, procedures and safe work method statements help form the safety management plan.

An evaluation of the impact of safety culture on quality in construction organisations revealed that better work methods and reduced absenteeism had contributed to improved organizational performance, while also impacting on product quality. Similarly, construction industry studies have shown that projects driven by safety are more likely to be on schedule and within budget. Major investments in safety in the British steel industry not only resulted in significant reductions in accidents with corresponding increases in productivity, but also led to increasingly positive attitudes about quality and safety.

1.17 THE IMPACT OF SAFETY CULTURE ON RELIABILITY

The impact of safety culture on the reliability of technological systems is thought to be indirect through organisational structures and processes: partly because the reliability of complex technical systems is dependent on the quality of its structural components and sub systems; partly because human reliability is dependent on the variability of human error probabilities; and, partly because of the interaction between them. Reliability has been reported to improve by a factor of three, and sometimes by as much as a factor of ten, when quality improvements are initiated. It is likely, however, that some of these improvements are related to the use of better monitoring and feedback systems, both of which are vital safety culture features, and as a result of streamlining production processes.

1.18 THE IMPACT OF SAFETY CULTURE ON COMPETITIVENESS

A good safety culture can also contribute to competitiveness in many ways. It may make the difference between winning or losing a contract it may affect peopleâ&#x20AC;&#x2122;s way of thinking and lead to the development of safety features for the project activities which are then used as marketing means and it positively impacts on employeesâ&#x20AC;&#x2122; commitment

15 and loyalty to the organisation, resulting in greater job satisfaction, productivity and reduced absenteeism.

1.19 THE IMPACT OF SAFETY CULTURE ON PROFITABILITY

Although a focus on safety has often been seen as non-productive expenditure demanded by law, it can also contribute to profit by minimising loss and adding to the capital value of an organisation. Construction industry research has shown that an investment of 2.5% of direct labour costs in an effective safety program should, at a conservative estimate, produce a gross saving of 6.5% (4.0% net) of direct labour costs. As a whole, the available evidence indicates that an effective safety culture is an essential element of any business strategy, as it has so many positive effects on other areas of business performance. It also illustrates the point that safety culture does not operate in a vacuum: it affects, and in turn is affected by, other operational processes or organisational systems.

1.20 BENCHMARKING

Benchmarking is a management technique to improve business performance. It is used to compare performance between different organisations or different units within a single organisation undertaking similar processes. Benchmarking is one of the ongoing methods of measuring and improving products, services and practices against the best that can be identified in any industry anywhere. It can also be defined as the search for industry best practices which lead to superior performance. Unlike traditional competitive analyses which focus on one industry and its benchmarks, benchmarking can compare the ways in which similar processes are carried out irrespective of whether the outputs are different or difficult to measure. Benchmarking is a very versatile tool that can be applied in a variety of ways to meet a range of requirements for improvement. A benchmark is "the best in class" performance achieved for a specific business process or activity. It is the performance that has been achieved in reality and can be used to establish improvement goals.

16 1.21 TYPES OF BENCHMARKING

Benchmarking can be carried out against any organisation or target that is deemed to be best in class. A full benchmarking exercise will involve not only the collection and comparison of data, but will include fact-finding studies to unearth the reasons for superior performance. The following are the three types of benchmarking. â&#x20AC;˘

Internal Benchmarking

â&#x20AC;˘

Competitive Benchmarking

â&#x20AC;˘

Generic Benchmarking

1.21.1 Internal Benchmarking Internal benchmarking is a comparison of internal operations such as one site against another within the same company. Large companies will often have plenty of scope for this sort of benchmarking, and should aim to bring the level of performance of the whole company to the current best in company.

1.21.2 Competitive Benchmarking Competitive benchmarking is a comparison against a specific competitor for the product, service or function of interest. This will provide data and information about what competitors are achieving. It is more difficult and complex to carry out.

1.21.3 Generic Benchmarking Generic benchmarking is a comparison of business functions or processes that are the same, regardless of industry or country. A ready-mix concrete company compared its delivery performance against a pizza delivery company is type of generic benchmarking. Both were in the business of delivering products which had to arrive at the point of use promptly.

17 1.22 BENEFITS OF BENCHMARKING

Although the major focus of benchmarking is usually planning and organizing, one of its main objectives is to introduce new ideas to an organization. One of the implications of the benchmarking process is that organization needs to overcome their internal boundaries in order to assess opportunities and threats in the external environment. In this context, benchmarking can be used to identify innovation by helping management understand the external environment and by promoting organizational learning. Organisations that use benchmarking successfully report that the cost of benchmarking is repaid at least ten-fold. Benchmarking can be used to help identify which processes to improve that is, the area we aim to achieve the best. It ought to help set targets - that is, what is the gap between our organisation existing processes and the best practice found in other organisations. It can also help when used in conjunction with a number of performance improvement techniques, such as business analysis and redesign of business processes.

1.23 BARRIERS OF BENCHMARKING

There are several barriers to the implementation of performance measurement systems in the construction industry, due to the peculiarities of this sector. These barriers arise because 1. Construction is project-oriented industry and each project is unique in terms of design and site conditions 2. Establishing a project performance measurement system and incorporating the measures into the company routine require a fairly intense effort; 3. The responsibilities for data collection, processing, and analysis, in general are not well defined at the beginning of the project; 4. Each project usually have a different managerial team and the use of measures will depend on the capabilities and motivation of each manager. To combat these barriers. 5. Benchmarking initiative demands a joint effort from several organizations, such as governmental entities, construction client’s individual companies, research institutions, and industry organizations.

1.24 PROCESS

Benchmarking consists of a logical sequence of stages which an organisation goes through to achieve continuous improvement in its key processes. It involves using reference models as the starting point. The process include the following, •

Facilitate change

•

Provide senior management support

•

Involve process owners. Their involvement encourages acceptance and buy-in by those who will be affected immediately by the changes which will be required to improve performance

•

Set up benchmarking teams. As a benchmarking culture develops, people will apply the method as part of the normal way in which they manage their work

19 •

Acquire the skills. People who undertake benchmarking require a small amount of training and guidance. An experienced in-house facilitator or external consultant will probably be required to provide technical assurance and encouragement in making use of reference models. The method can be applied at various levels from relatively straightforward in-

house comparisons through to industry-wide search for best practice. It comprises four basic stages: planning, analysis, action and review.

1.24.1 Planning •

Selecting the broad business process or function to benchmark Within that process defining the activity to be benchmarked Identifying the resources required for the study

•

Confirming the key performance measures or indicators to measure the performance in carrying out the activity

•

Documenting the existing way in which the activity is carried out

•

Identifying appropriate reference models as a starting point for your assessment; you may also find supplier intelligence information useful

1.24.2 Analysis •

Collecting information to identify the scope for improvement

•

Comparing the existing process with that of appropriate reference models to identify differences and innovations

•

Agreeing targets for improvement which are expected as a result of adopting new ways of doing things.

1.24.3 Action •

Communicating the results of the study throughout the relevant parts of the organisation

•

Planning how to achieve the improvements

•

Implementing the improvement plan, monitoring progress and reviewing as necessary.

20 1.24.4 Review •

Reviewing performance when the changes have been bedded in

•

Identifying and rectifying anything which may have caused the organisation to fall short of its target

•

Communicating the results of the changes implemented to the organisation

•

Considering benchmarking again to continue the improvement process.

1.25 OBJECTIVE

It is clear from the construction industries safety record that there is room for improvement in the implementation of safety procedures and guidelines. However, no attempts have been made to define what is really meant by management’s commitment to construction safety and what steps must be followed to achieve an effective commitment to safety. The problem becomes further complicated in case of small and medium level establishment. The top level contractors are growing while the medium level contractors are lagging behind mainly because of their quality and safety standards.

The objective of the present study is to find the construction safety factors affecting the medium level contractors and to improve their safety performance.

Therefore, the main objectives in this study are: 1. To find the safety factors affecting the small and medium level contractors. 2. To identify the relationship between managements commitment to safety and the safety record of a company. 3. To identify what are the factors affecting construction safety. 4. To identify what attributes are presenting a successful commitment. 5. To prepare a booklet of minimum safety precautions to be followed in construction activities.

CHAPTER 2

REVIEW OF LITERATURE

A vast review of literature in the field of construction safety and benchmarking initiatives in construction were available. The author deals with few of literature that was collected.

Ron Sharpe et.al (1995) have developed an "assessment tool or model" to identify risk factors for employees that will identify personnel whose understanding of safe work practices is such that it places them, and those with whom they work, at a higher risk of being involved in an accident. They have developed further tools to bridge the gap in safety including motivational, personal skills and other support systems to improve their safety awareness and to provide the appropriate personnel with the safety tools and thereby minimise the likelihood of them being involved in an accident. They have tracked the effectiveness of the program against key performance indicators. They have urged to automate as much information handling as possible via computer based systems to assist in the delivery of the assessment and training program and also help the industry overcome access and resource problems, reaching sub-contractors and aiding cost effectiveness.

Tang.S.L et.al (1997) worked out a method which will help improve construction safety proactively by correlating the two auditing scores (quality and safety) with safety performance. The principle objective of this work was to develop two indicators. The first indicator is the relationship between accident rates and quality auditing scores and the second one is the relationship between accident rates and safety auditing scores. The indicators would be in the form of simple graphs relating accident rates with the scores achieved in quality audit and safety audit exercises being used by local construction contractors. Both problems inherently reflect the insufficient effort input by management of the construction contractors.

22 Helen Lingard et.al (1998) have aimed to test the effectiveness of Behavioral Safety Methods (BSM) by applying goal-setting and feedback interventions to specific areas of safety performance on Hong Kong Housing Authority construction sites. Using a within-group experimental design and with the use of a proportional rating safety measurement instrument, data were collected on the effectiveness of BSM on Hong Kong sites. The data were analyzed using autoregressive moving averages models, and the results were mixed in that a significant improvement in safety performance occurred in the housekeeping category of intervention but no improvement was observed in the access to heights and bamboo scaffolding categories. They concluded with a goal setting/expectancy theory model of site safety improvement has been synthesized, and the lack of provision of an adequate safety infrastructure has been identified as a serious impediment to improvement. Edwin Sawacha et.al (1999) have discussed the factors influencing safety on construction sites. The impacts of the historical, economical, psychological, technical, procedural, organizational and the environmental issues are considered in terms of how these factors are linked with the level of site safety. The historical factor is assessed by the background and characteristics of the individual, such as age and experience. The economic factor was determined by the monetary values which are associated with safety such as, hazard pay. The psychological factor is assessed by the safety behavior of fellow workers onsite including supervisors. The technical land procedural factors were assessed by the provision of training and handling of safety equipment on site. The organizational and environmental factors are assessed by the type of policy that the management adapts to site safety. Information regarding these factors was correlated with accidents records in a sample of 120 operatives. The top five important issues found to be associated with site safety were: (1) management talk on safety; (2) provision of safety booklets; (3) provision of safety equipment; (4) providing safety environment and (5) appointing a trained safety representative onsite. Albert W.K. Kwok. et.al (2000) outlines the results of research conducted with Civil Engineers regarding their views and knowledge on Construction Design and Management (CDM) regulations. The CDM regulations were introduced in the United

23 Kingdom on 31st March 1995 in compliance with European Directives. The objectives of this regulation were to improve construction safety by enhancing co-ordination and communication among project parties through out all stages of the construction project. The results revealed that more than 95% of the respondents did not know about the requirements of CDM regulations.

Joe M. Wilson. et.al (2000)

presented a discussion of the methods of safety

management employed on a small to medium sized project in the northwestern United States. It was stated that the principles behind safety management are fairly simple in concept; it was during the implementation of such a program that construction companies may encounter their most difficult obstacles. Therefore, the process must be constantly monitored and adjusted to achieve the desired goals. They had highlighted several of the problems encountered and the solutions utilized to overcome these problems.

Christopher Auld .M. et.al (2001), have measured the impact of on-site safety inspections on the frequency of work-related injury and death in the Alberta construction sector. The data were disaggregated by sub industry allowing different risk levels to be associated with different work activities. In the sample study, there was a dramatic decrease in inspection activity, which allows us to assess the necessity for continuing with current levels of inspection effort. It was concluded that the on-site safety inspections have no effect on the risk of accident and injury but have a positive effect in reducing the number of work-related fatalities.

Satish.B.Mohan.et.al (2002) have prepared a checklist based on the past records and Occupational Safety and Health Administration (OSHA) guidelines. It was observed that over 75% of all cases brought before the Occupational Safety and Health Review Commission (OSHRC) were serious violations or worse. This means that the standards being violated and contested are placing employees at risk of being injured. They concluded that to better protect employees; the employers must be made aware of what is required for them in regard to safety. With more concise and clear language, the

24 standards would be easier to follow. It was also stated that the employerâ&#x20AC;&#x2122;s motivation is required for providing a safety environment.

Sherif Mohamed (2003) adopted the balanced scorecard tool to benchmark organizational safety culture in construction. He emphasis that this tool has the potential to provide a medium to translate the organizationâ&#x20AC;&#x2122;s safety policy into a clear set of goals across four perspectives: management, operational, customer, and learning. These goals were then further translated into a system of performance measures that could effectively communicate a powerful strategic focus on safety to the entire organization. Four perspectives have been developed to represent all stakeholders, thereby ensuring that a holistic view of safety is used for strategic reflection and implementation. He insisted that by selecting and evaluating the appropriate measures, in each perspective, requirements can be identified, and actions to the identified goals can be aligned and facilitated. He proposed the balanced scorecard approach to enable construction organizations to pursue incremental safety performance improvements. Work-in-progress is briefly reported to give insight into the potential applicability of this approach.

Evelyn Ai Lin Teo et.al (2004) proposed a policy, process, personnel and incentive framework which may help project managers manage construction site safety. A postal survey of contractors in Singapore was conducted by them to test the framework. It is found that site accidents are more likely to happen when there was inadequate company policies, unsafe practices, and poor attitudes of construction personnel, poor management commitment and insufficient safety knowledge and training of workers. It is recommended that project managers need to pay more attention to the important factors identified in this study to help them enhance performance at construction sites and reduce the frequency of accidents. The main finding of this study was that site safety is affected by four main factors: company safety policy; construction process; personnel management with regard to safety; and incentives. In terms of safety policies, it recommended that project managers implement policies relating to safety management systems.

25 Fang.D. P et.al (2004) presented information by which to measure safety management performance on construction sites. They have identified the key factors that influence safety management and have developed a method for measuring safety management performance on construction sites. Based on the survey and interview data collected on safety management factors in 82 construction projects in China, the safety management index as a means to evaluate real-time safety management performance by measuring key management factors was developed. The quantified factors were compared with the commonly accepted physical safety performance index, which was derived from inspection records of physical safety conditions, accident rates, and the satisfaction of the project management team. Based on this benchmarking study, a practical safety assessment method was developed by them and then implemented on six construction projects. Their results proved that this method can be an effective tool to evaluate safety management on construction projects.

Ricardo RamĂrez.R et.al (2004) presented the results of the first application of a management evaluation system for benchmarking management practices in the construction industry. The system supports a National Benchmarking System recently established in the Chilean Construction Industry by incorporating qualitative management aspects in addition to quantative performance indicators. Different analyses were made to determine trends in the industry sector by correlating the qualitative evaluations from surveys with the performance indicators. Thirteen construction companies participated in the initial application of the benchmarking system. A correlation analysis carried out by them and found that safety performance was strongly related to companies having superior planning and control, quality management, cost control and subcontractor management policies.

John A. Gambatese. et.al (2005) presented a pilot study that was conducted to investigate the practice of addressing construction worker safety when designing a project and to determine the feasibility and practicality of such an intervention. It was found through interviews with architects and engineers that a large percentage of design professionals are interested and willing to implement the concept in practice. They

26 described the key changes needed for implementation of the concept in practice which include: a change in designer mindset toward safety; establishment of a motivational force to promote designing for safety; increase designer knowledge of the concept; incorporate construction safety knowledge in the design phase; utilize designers knowledgeable about design-for-safety modifications; make design for safety tools and guidelines available for use and reference; and mitigate designer liability exposure

Michael Toole.P.E (2005) suggested the role of engineering and construction professionals in construction safety. He identified that the Civil Engineers could contribute to construction worker safety by performing five tasks differently than current custom and practice namely reviewing their designs, creating design documents, assisting the owner in procuring construction, reviewing submittals, and inspecting work in progress. He have identified four sets of major barriers that prevent designers from increasing worker safety through these tasks, namely lack of safety expertise, lack of understanding of construction processes, typical contract terms, and professional fees. Potential ways for reducing these barriers were suggested by him. The United Kingdom regulations required engineers to design for safety are summarized, but it is concluded that similar legislation in other countries would not be appropriate.

Todd W. Loushin et.al (2005) described that a significant portion of construction contract money was wasted due to insufficient planning and project mismanagement. They conducted interviews with management representatives to gain insight into their perception and use of safety and quality management in construction. From a safety standpoint, the sample admitted using similar performance measures. From a quality standpoint, the contractors relied on a variety of subjective or after-the-fact measures for quality. Worker attitude and lack of skilled workers were cited as major barriers to the improvement of quality and safety. They had concluded that the respondents did not see the potential benefits of integrating safety and quality management to reduce injuries while improving productivity.

27 Dayana.B.Costa et.al (2006) have discussed initiatives to develop performance measurement systems for benchmarking in four different countries the United Kingdom, Chile, the United States, and Brazil. Their study pointed out some of the benefits, problems, limitations, and opportunities for improvement of these initiatives. The lessons learned should be used for upgrading the existing initiatives and devising new ones. A joint effort involving several organizations is necessary for the successful design and implementation of benchmarking programs. Such an effort should not be limited to data collection but should also provide data analysis and training, as well as enable the exchange of best practices among the companies aiming to promote innovation. Moreover, these measures should be assessed and revised periodically, according to the needs of the companies involved. The commonalities among these initiatives indicate that they potentially could be used for International benchmarking.

Gregory Carter et.al (2006) presented an investigation indicating the current levels of hazard identification on three U.K. construction projects. Their study reveal that a maximum of only 6.7% of the method statements analyzed on these projects managed to identify all of the hazards that should have been identified, based upon current knowledge. Maximum hazard identification levels were found to be 89.9% for a construction project within the nuclear industry, 72.8% for a project within the railway industry, and 66.5% for a project within both the railway and general construction industry sector. Their results indicate that hazard identification levels are far from ideal. They had concluded with an information technology tool for construction project safety management and, in particular, a module within total-safety designed to help construction personnel develop method statements with improved levels of hazard identification. OsamaAbudayyeh et.al (2006) have carried out a study to determine the correlation between management commitment to safety and the frequency of construction-related injuries and illnesses. To achieve this purpose, a survey was developed and sent to a random sample of the top five hundred US construction companies. Survey results point to a clear statistical correlation between management commitment on safety and injury and illness rates. The costs resulting from injuries and

28 equipment damage, combined with the associated financial loss resulting from schedule disruptions, insurance hikes, and workers compensation, impact the profitability of any construction operation. They have concluded that these costs may be minimized or avoided through focused safety efforts on construction job sites. Xinyu Huang et.al (2006) described the owner’s role in construction safety. They were claiming that the recent improvements in construction industry were due to the concerted efforts of owners, contractors, subcontractors, and designers. While past safety studies have investigated the roles of contractors, subcontractors, and designers, the owner’s impact on construction safety has not been previously investigated. Data were obtained by conducting interviews on large construction projects. The relationship between project safety performance and the owner’s influence was examined, with particular focus on project characteristics, the selection of safe contractors, contractual safety requirements, and the owner’s participation in safety management during project execution. By identifying practices of owners associated with good project safety performances, the author has given guidance on how owners directly impact safety performance.

Guidelines for safety management plans published by the workplace standards Tasmania deals with the importance of safety management plans in construction industry. It had clearly discussed the factors that have to be added in safety management plan. The factors include management commitment, policies, legal requirement, resources, training and competency, inspection and auditing etc.

CHAPTER 3

METHODOLOGY 3.1 METHODOLOGY

The present study was conducted to establish a benchmark to measure real-time safety management performance on construction sites. The methodology adopted in this work is the collection of data by the method of survey. Surveying with a help of questionnaire was found to be most efficient based on the literature review conducted by the author. The work can be divided into four phases namely: •

Preliminary study phase

•

Data collection phase

•

Data analysis phase

•

Implementation phase.

In the preliminary study phase, an initial step was to identify factors that might influence construction safety management. The process of developing the factors began with a view of the literature. The criteria to select such factors include 1. Validity: the factors must be closely related to safety management practice on site; 2. Quantifiable: the factors should be objectively defined and can be expressed as an numeric value; and 3. Realistic: the factors must accurately reflect actual situation on construction projects, based on the consideration of both the cultural and economic aspects of the projects.

30 QUESTIONNAIRE STRUCTURE

The objective of the present study is to carry out a benchmarking study on construction safety. This work is based on the questionnaire survey carried out in construction site. The questionnaire is designed to collect data regarding their current safety provision and implementation in the site. The questions are designed mainly to obtain the information regarding their safety investment, accident cost, importance given for safety at site. Totally ten general questions, twenty open ended questions, sixteen optional question and thirty one question based on Likert scale were framed. In case of Likert scale a five point scale was used. The questionnaire was designed based on the following eight factors. 1. Project nature 2. Historic factors 3. Organizational structure 4. Management measures 5. Individual involvement 6. Economic investment 7. Labour management relation 8. Causes and remedy for accident

The effectiveness of the designed questionnaire was checked with the help of a pilot survey carried out in the first phase of the project work. The pilot survey was carried out with four construction companies in Chennai. The questionnaire was modified based on the feedback of the survey.

In the date collection phase the data was obtained from ninety construction companies mostly around Chennai and other major cities in Tamilnadu. The construction sites were visited in person and the questionnaire was distributed to the concerned person. The response was obtained immediately or collected later at the planned time. The projects that were executed currently by the surveyed companies are mostly residential complex and information technological parks. The cost of the project varies from eight crores and

31 one hundred and twenty crores. The respondents were mostly project managers and site engineers.

In the data analysis phase the questionnaire was numbered when it is obtained from the respondent. The data analysis sought to establish the variables that affect construction safety. The mean and standard deviation for each response was made for the optional questions and Likert scaled questions. In case of other questions the total response of the questionnaire is counted. The results are presented in terms of tables and charts.

In the implementation phase, based on the results of the survey conclusion was made and the results are presented. A booklet of minimum safety precautions to be followed in construction sites was prepared based on the available codes and guidelines. The booklet was prepared keeping in mind the medium and small level contractors who are lagging behind in construction safety standards. The booklet was distributed to the companies for possible implementation in their construction site, to minimise accident and to improve safety in their construction sites.

CHAPTER 4

34 The percentage of safety investment that was made by the companies is less and not defined clearly. The general types of accident that commonly occur in construction site as observed by the respondents are stated below: 1. Falling from height. 2. Failure of temporary structures. 3. Fall of objects. 4. Hit by object. 5. Electrocution. 6. Slippage. 7. Caught in between. 8. Collapse. The cause for the accidents as stated by the respondents is shown in Figure 4.3. Out of the ninety companies surveyed accident has occurred in twelve construction sites. There is no fatality in the surveyed companies. The damages that are reported after an accident are worker injury, loss of man days, wastage of material, breakage of form materials, financial claims, etc. The financial loss in terms of claim for medical treatment to injured worker, insurance claims and material costs vary from rupees ten thousand for minor injuries to one lakhs fourty thousand rupees. Out of the ninety companies surveyed four companies face legal suits for the cause of accident. Coworker 6%

Unsafe act 9%

35 Out of the companies surveyed only thirty two companies (35 percent) have a separate safety department. In the remaining companies the safety measures are taken care by the execution department. Seventy four companies (82 percent) admitted that the top management has involvement in safety measures at site. The site safety is checked frequently by the top managements of these companies. In most of the companies the supervisors are given authority to stop work for identified hazards. Fourty companies (44 percent) accepted that they do not provide adequate personal protective equipment to their workers. In most of the companies even though the company provide adequate personal protective equipment, due to non availability of strict rules and regulation the workers are not using them properly.

Project managers of twenty two companies (24 percent) attend safety meeting regularly. Almost all the companies surveyed have first aid facility in site and pays for the medical expenses of the injured workers, only six companies (7 percent) have medical practitioner available in site during the working hours. Totally fifty two companies (58 percent) provide safety training to their workers and seventy eight companies (87 percent) accepted that the training given to workers are effective. Fifty companies (56 percent) keep daily safety records of the project. Very few companies provide workers compensation insurance for their injured workers. All the companies accepted that the schedule pressure in completing the project was passed directly to construction workers. Six companies (8 percent) have won safety award. The results are shown in figure 4.4.

Figure 4.4 Bar chart for survey results

Most of the companies that take part in the survey have a separate environment health and safety (EHS) document. But the safety provisions that are recommended in the EHS document are not implemented in construction sites.

The results of the Likert scaled questions are shown in Table 4.3. The mean value of all the factors that affect construction site safety vary between 2.22 to 4.78, which emphasis that in the whole of the companies that was surveyed the safety features are between low and very high level.. Out of the thirty one factors considered three factors were ranked as very high, ten factors as high, fourteen factors as medium and four factors

37 as low effect with respect to safety. The coordination and control of sub contractor, control on sub contractorâ&#x20AC;&#x2122;s safety behaviour and the provision of personal protective equipment by the company were ranked as top three factors that affect construction safety with an average mean of 4.78, 4.72 and 4.56 respectively.

The standard deviation (Ď&#x192;) of the respondents varies around 1, revealing that the response is same for all the companies. The maximum deviation of 1.19 and 1.18 was observed in case of usage of heavy equipment and application of new technology in the project respectively. This is due to the reason that most of the companies surveyed use traditional methods for building construction. The management of most of the companies is not willing to invest much on plant and machinery. Implementing the safety practices in construction sites was a major hurdle as said by the respondents. This is mainly due to the lack of management commitment/ interest in safety measures.

CHAPTER 5

CONCLUSION 5.1 CONCLUSION

The work environments in construction activities are generally more hazardous than other industries due to the use of heavy equipment, dangerous tools, and hazardous materials, all of which increase the potential for serious accidents and injuries. Therefore, it is evident that a focused dedication towards safety is needed from construction at all levels. It can be inferred from the survey data that safety managers have the opportunity to influence and enhance the sense of safety and the quality of the work environment. Owners of large projects can more actively participate in construction safety management in each stage of project execution, including project design, contract selection, contract development, the construction phase, selecting safe contractors, and developing the safety culture on the projects through safety training and safety recognition programs.

A questionnaire was prepared based on the literature survey conducted by the author. The questionnaire was distributed to two hundred companies and ninety responses were obtained in time. Fundamental statistical analysis was carried out with the completed questionnaire and the results are reported. The mean value of all the factors considered for Likert scaled question vary between 2.22 to 4.78 and the standard deviation vary around 1.

The important finding of this study is that site safety is affected by company safety policy; construction process; personnel management with regard to safety. If these factors are addressed and monitored closely, accident reduction may be realized in construction sites. The construction companies shall also be willing to give safety training/awareness to the construction workers to reduce and eliminate the future lost time injuries, time and cost. Certain ground rules need to framed by the construction companies for effective and efficient use of personnel protective equipment.

40 The results show that it is very important for both workers and supervisors to adopt safe work behaviours. The willingness of workers to adopt safe work practices also depends largely on the perception of safety, level of safety education and training received, cultural back-grounds and communication between fellow workers and superiors. Supervisors play an important role in influencing their workers in the adoption of safe work behaviours. The supervisor’s safety behaviours and actions have a direct impact and influence on workers. To portray positive safety behaviours, supervisors are required to lead by example, integrate safety into all phases of the job, never ignore near miss occurrences and have no blame cultural mind sets.

The results also show that the influence of management on the safety and health standards on site is very crucial. The responsibilities and roles that management plays will determine the over all safety performance of the entire site. Safety culture has to be adopted in all organisations through strong support and encouragement by senior management. By management’s endorsement, safety promotion will boost the morale and motivate site personnel to think and works safely.

A booklet was prepared based on the “Building and other construction workers (regulation

of employment and conditions of service) rules, 1996”. The booklet was

distributed to small and medium level construction companies for possible implementation on their construction sites.

5.2 SUGESSION FOR FUTURE WORK

1. The questionnaire can be modified based on the need for a particular type of project and surveyed. 2. The survey can be carried out by separating the construction companies based on the factors like type of company, annual turn over, location of the company, etc. 3. Statistical analysis can be further carried out to explore the results of the survey. 4. The effective use of the booklet prepared can be checked and corrections can be made based on the needs of the construction site requirement.
