Since, 1860s there has been evolution of road construction by first introduction of railway system as a means of goods transport in Mauritius. However, in 1964s railway system was stopped due to persistent unprofitability and there was the introduction of motorized transport. There has been construction of road networks to cope with the increasing road traffic congestion like goods vehicles, buses, cars, motor etc. There are 2 066 km of roads in Mauritius in which 48.5% are main roads, 28.7% are secondary roads, 3.6% are motorways and the remaining 19.2% are made up of other types of roads. Three major road construction companies involved in the decongestion of roads in Mauritius namely Rehm-Grinaker Construction Co. Ltd, Gamma Civic Ltd and Colas (Maurice) Ltée.


Colas were established in Mauritius since 1986 as (A&J Maurel Construction Limitée) which is now registered as Colas (Maurice) Limitée since June 2009. It is a leader in the construction and maintenance of road, air, rail and transport infrastructure, urban development projects and recreational facilities. Colas (Maurice) Ltée has played a significant role in the development of the national road networks in Mauritius and Rodrigues.


Colas first came with 1 Asphalt Plant for the road construction in Mauritius as the main projects were given mostly to other companies. Now Colas (Maurice) Ltée has 4 Asphalt Plant in operation in Mauritius and as a result of its long established experience and trustworthiness in road construction, Colas (Maurice) Ltée had been awarded some main contracts which are as follows:

Realignment of Laventure Road,

Construction of Gros Bois - Mare D'Albert Link Road,

Triolet Bypass,

Second Carriageway, Pamplemousses to Forbach,

Widening of Motorway M1 between Pailles and Caudan

Construction of Port Louis Ring Road- Phase 1 from Montebello to Guibies

With the good completion of these major projects, Colas (Maurice) Ltée is now with an ongoing construction of the Terre Rouge-Verdun-Trianon Link Road and the Runway and Parallel Taxiway at the Airport of Mauritius. The company has set up a new hot mix Asphalt Plant different from the other 3 Asphalt Plant in Plaine Magnien on a site next to a stone crushing plant belonging to United Basalt Product Ltd (UBP). The Asphalt Plant there is actually producing for the construction of the Runway of the Airport and it receives aggregates from the stone crushing plant nearby which is helping a lot to complete the project right on time.


The Occupational Safety, Health & Welfare Act 1988 was repeal and replace by Occupational Safety and Health Act 2005 in October 2005 as the dynamism of the world of work necessitates a constant scrutiny of the law. The OSHA 2005 aims at "consolidating and widening the scope of legislation on safety, health and welfare of employees at work". This Act unreservedly binds the State, meaning it is applicable invariably in the public sector.

However this Act is not yet in force; it is awaiting proclamation. If it were to be enforced now, the government itself, as employer, would be in contravention due to the scarcity of Safety and Health Professionals at the moment.

OSHA 2005 is not much different from OSHWA 1988, except that it contains more elaborate provisions with regard to duty holders' responsibilities. Also some implicit provisions in the previous law have been rendered more explicit. For instance there are specific provisions with regard to risk assessment, safety and health policy, vehicle lifts, escalators, manual handling operations and health surveillance of employees. The penalties for offences have been reinforced.

Every workplace risk exist which may cause danger to the health and safety of employees. It is therefore necessary that mitigating actions are taken to protect workers and other people who may be affected from these hazardous situations. There are number of control methods that can be used to tackle occupational hazards. Controlling a hazard at its source is the first and best choice because this method will eliminate it from the place of works altogether or will isolate it from the workers. However, it is imperative to first of all identify the hazards and to take the required action to reduce the risk or eliminating them. Risk Assessment is therefore one essential component in the hierarchy of controls that can significantly reduce the number of accidents and injuries in the workplace. Regardless of whether a workplace, a workshop or a company is involved, such an analysis allows to form the hierarchical order of hazards depending their dimension and the efficient assignment of resources for priority measures.

Risk assessment implies the identification of all risk factors within the system under examination and the quantification of their dimension, based upon the combination between two parameters: severity and frequency of the maximal possible consequences for the human body.

Management participation is fundamental in preserving a health and safety condition at work. OSHA (2005) places a legal duty on employer to provide a safe work setting. According to section 5(1) of OSHA (2005) it states that "Every employer shall, so far be reasonably practicable to ensure the safety, health and welfare of all his employees". An employer has the duties under OSHA (2005) to assess risks in the workplace. Risk assessments shall be carried out by employer so as all risk is being identified and preventive measures are being taken.


In construction industry, it could be the likelihood of the occurrence of an event or a combination of events which occur during the whole process of the construction that are risky. In the various definitions of risk, there are many different ways of categorizing risk in a construction industry. Some categorize risk as external risk and internal risk and in more detailed categories risk as political risk, financial risk, market risk, social risk, safety risk, etc. Since construction works have changed significantly over the past several years with the use of new technologies, it also represents greater risk than older ones. Thus, risk assessment is a tool to identify those risks in a project and manage it accordingly with proper treatment.

Risk is inherent and difficult to deal with. Risk Management is a formal and orderly process of identifying, analyzing and responding to risks throughout the life-cycle of a certain construction project to risk elimination and control.

Some sources of risk in construction projects are:

Misunderstanding of Contracts

Poorly defined responsibilities

Unskilled staff

Poor coordinated work


The types of exposure to risk that an organisation is faced with are wide-ranging and vary from one organisation to another. These exposures could be the risk of business failure, the occurrence of major construction accidents and organisation risks. It is desirable to understand and identify the risks as early as possible so that proper control can be implemented to retain particular risks or to transfer them to minimize any likely negative aspect they may have.

As Colas is involved in many activities such as construction of roads and buildings, Safety and Health is the integral part in the organization. Most of their employees carry out their work on-site and while performing their activities, different types of hazards and accidents occurred which could be prevented by risk assessment. The employees are also provided with PPE but they do not use it in a proper manner and for some among them, they are not comfortable with the PPE. Risk Assessment plays a fundamental role in identifying the types of hazards and recommending measures to minimize or eliminate the risk. The risk register shows that there is an increase in accidents on the asphalt plant industry.











Table 1 Number of accidents

Figure 1 Number of accidents

Figure 1 represents the number of accidents that normally occurred at colas sites. As it can be found that every year accident occurs and the highest number of accidents occurred in 2010. The accidents are obviously in connection to the number of construction projects given to the company and the management commitment towards safety of employees. The number of accidents until mid-year 2012 was found to be about 39 which could increase more by the end of the year. Identification of the main types of hazards and taking remedial measures is fundamental in reducing the rate of accident.


1.7.1 Aims of the project

The main aim of this assessment is to develop a risk assessment plan while doing surveys and risk assessment in order to reduce the level of hazards and accidents on the asphalt plant industry.

1.7.2 Objectives of the project

Evaluate the effectiveness of risk assessment in identifying the risk of an asphalt plant industry for the construction of the Parallel Taxiway at the Airport of Mauritius.

Analyze how risk assessment can reduce risk, be cost effective and increase productivity.

To evaluate the type of health hazards involved in an asphalt plant

To propose recommendation based on the research findings so as to minimize the health hazards to employees.


In order to achieve the aim of this assessment, and to help the employees to have a safe place of work, these tools would be useful:

Data collection through survey, questionnaire, interview and observations,

To propose measures for the risks identified, do a risk assessment,

Risk assessment matrix,

Data analysis through SPSS software which is a Predictive analytics program which helps an organization to anticipate change to improve outcomes through planning and implementations of strategies.

2.3.4 Health and Safety Department

Colas Mauritius reinforces its action towards the prevention of work related accidents for all of its activity. Indeed, increase labor force and the recruitment of staff that are not familiar with site activity amplify the risks of accidents. While benefitting from the exchange of good practices and experience of other branches of the group, Colas Mauritius has defined a security policy adapted to its activities and to the particularities of the local environment.

With a continuous frame of mind, the frequency and gravity of work related accidents are monitored via indicators so as to meet annual targets. Action plans are implemented base on the assessment of the risks and the finding of the root causes of the work related accidents.

The elaboration of the safety policy of colas Mauritius is based on the specific health and safety recommendations: monthly "safety talks", training module (road safety, scaffolding assembly, operating construction equipment, handling of fire extinguishers, etc.), enhancing awareness about the important of personal safety equipment and safety audits.


After the completion of the Ring Road Phase 1, Pailles to Caudan, the major projects that Colas is working on are the Terre Rouge-Verdun-Trianon Link Road which is a first in Mauritius and the Runway and Parallel Taxiway at the Airport of Mauritius. For these constructions, Colas is using its own Asphalt Plant where it produces the different types of asphalt needed with the mixture of bitumen and aggregates which it takes from UBP and Gamma. Colas has always been placing its Asphalt Plant on the site where the stone crushing plant is found and near the construction sites so that it is easy for the loading and unloading of materials and asphalts.


Construction workers are at risk of exposure to various health hazards that can result in injury, illness, disability or even death. Different types of health hazards are grouped as:





Chemical are fond in variety of products used at construction sites. Workers may also be exposed to chemicals generated during construction activities and these hazards are: dusts, fumes, liquids, gases, vapors and fibers (solids). Physical hazards are different types of energy which may be hazardous to workers and these include: noise, vibration, temperature extremes and radiation. Biological hazards also can cause diseases or illnesses for example, bacteria and viruses. Ergonomic hazards can cause painful and disabling injuries to joints and muscles and these occur from:

Heavy, frequent or awkward lifting

Repetitive tasks

Excessive force

Using wrong tools for a particular job or simply using the tool improperly

Ergonomic hazards are the most frequently occurring health hazards in construction and the cause of most injuries.


The site chosen for this assessment is the Runway and Parallel Taxiway at the Airport of Mauritius. Apart from road construction, Colas also provide extensive airside capabilities and expertise on all aspects of airfield pavement construction and maintenance. Employees working at the Asphalt plant industry of the Parallel Taxiway, they are exposed to many health hazards resulting from their own work as well as from nearby activities. For example, they are exposed to materials that can cause serious illness and affect health in the long-term. Workers are also exposed to noise, vibration, chemicals and more hazards on the site. These types of hazards and risks should be prevented on construction sites and this can be done by doing a proper risk assessment.
