However each of the risk is different from the other. The identification the risk is based on the nature of works that will be undertaken before, and during the implementation of the project. The classification of the risk is based on the impacts that have been clearly highlighted in the risk register. The risks that is likely to have great negative effects on the project have been classified as catastrophic. Such risks are likely to increase the costs or contributed to major delays and failure of the project (Dėjus & Antuchevičienė, 2013). The risk that is likely to cause negative effects but may not necessarily lead to the project failure has been classified as significant. All the risks that are likely to cause minor delays as well as minor increase in the costs but may not affect the outcome of the project has been classified as moderate. The risks that have been classified as low do not have any impact on the project. The likelihood of the risk are dependant on the measures that have been put in place by the project owners as well as the general probability of such risks in the construction projects. The risk identification and classification plays an important role in determining the possibility of the project experiencing failure or success during the implementation process. Health and safety issues The construction industry is considered as one of the most dangerous sectors due to the nature of activities that are carried out (Oginni, Ogunbiyi & Balogun, 2014). A high number of injuries and deaths is usually reported every year at the construction sites. The health and safety issues are therefore important in order to minimize injuries and deaths. During the project to upgrade the works, some excavations will be carried out at the site. The workmen as well as the members of the public may be exposed to health and safety risks due to the nature of the activities. Hoarding must carried out and unauthorized entry to the site should be restricted. Clear sign posts should be placed at the site in order to indicate various activities or warn the people at the site. Accidents may occur at the site due to the use of different types of equipment and machinery. All the personnel handing the equipment and machinery should be qualified and competed. Guarding should be provides in all the excavations at the site. This is for the purpose of preventing the people from falling into the tranches. Substantial barriers should be placed at all the edges of the excavations in order to prevent accidents due to falls. All the personnel working at the site should be provided with personal protective equipment in order to minimize the chance of injuries during the construction process. During the manual handling process, the personnel should not lift the loads that are too heavy. All the personnel at the site must undergo training on safety. A safety code should also be developed and provided to all the personnel working at the site (Blake, 2013). A team that is equipped to provide first aid as well as treat minor injuries should be in place at the site. This is important ensuring that the health of the personnel is guaranteed during the construction process. The local Health and Safety Authority must also be notified of the plans and measures that have been put in place. Environmental issues The nature of the activities during the implementation of the project can result to environmental problems. Pollution due to the construction activities is a challenge that may result to environmental problems. Air pollution is one of the major environmental problems due to the nature of the construction activities. Noise due to the machinery and construction equipment is likely to cause environmental issues (Vesilind, Peirce &Weiner, 2013). This may however be avoided by using quite equipment as well as maintaining good site practices. Noise pollution may end up affecting the personnel at the site as well as the people living in the neighbourhood. Dust is likely to be generated due to the excavation as well as other construction processes. This can be minimized by ensuring some amount of water is poured on the surface in order to reduce dust which may result to air pollution. The pollution from dust is likely to cause respiratory problems resulting to poor health. Solid wastes from the excavation process and other construction activities will be generated. Poor disposal of the solid wastes can lead to environmental pollution. A solid waste management company can be subcontracted to handle all the solid wastes and ensure that pollution from solid wastes is prevented. Close monitoring and inspections should also be carried out from time to time to ensure that the construction activities are within the allowable limits in terms of environmental pollution. Consultation with the local environmental agencies is useful in ensuring the best practices are utilized to avoid adverse environmental effects (Vesilind, Peirce &Weiner, 2013). Constrains for the selected site The location of the project area is close to a road and it is also far from the residential areas. This is an indication that the project is not likely to attract much social constraints such as opposition from the community members and other stakeholders. However, to ensure that any form of social constrain is countered, the owner of the project must consult widely. The constraints may however be from the environmentalist as it may lead to pollution. The drainage system may end up affecting the water table or draining waste water to the roads and other unwanted areas (Oginni, Ogunbiyi & Balogun, 2014). Although there is a good road network to the site, it is located at the heart of the urban area. This may contribute to constrain regarding the transportation of materials to the site. It may take long for the materials to reach the site. The heavy trucks and equipment may also be faced with challenges in terms of turning as the road is narrow. Traffic at the road is likely to be interrupted by the heavy trucks as there is no junction to the site connecting the main road. Amount of cut and fill required on the site 1. Amount of cut and fill at the gross pollutant trap Area = Length X Width = 10 x 5 50  Depth of excavation = Maximum 3.6 M Volume of the pollutant trap = Area X Depth = 50 x 3.6 = 180  Amount of cut and fill required = 180  2. Amount of cut and fill at the reinforced concrete inlet Area = Length X width = 0.6 x 1.2 = 0.72  Depth of excavation = Maximum 2.6 m Volume of the reinforced inlet concrete = Area X Depth =0.72 X 2.6 = 4.87  The total amount of cut and fill required = 4.87  Amount of cut and fill at the outlet reinforced concrete pipe Area = Length X width = 0.675 x 0.6 = 0.405  Depth of excavation = Maximum 3.5 m Volume of the reinforced inlet concrete = Area X Depth = 0.405 x 3.5 =1.42 Amount of cut and fill required =1.42 The total amount of cut and fill required = 180 + 4.87 +1.42 = 186.29  A hydraulic excavator gas the ability of excavating about 250  per day. During the exaction the day can be considered as 8 hours. If the hydraulic excavator is used for the process, the entire work will be completed within 8 hours. However, back filling will be required in some of the sections and this may only last for less than a quarter of a day. Key site preparations requirements A number of activities needs to be carried out before the actual construction works begin. The permits as well as licences have to be obtained before any activity begins at the site. Permits from the environmental agency as well as works and building agencies are required. The local council should also be informed of the project in order to obtain the required permit. Site layout is an important activity that needs to be carried out before the construction process begins. This involves developing temporary facilities as well as amenities that will be required during the construction process (Dėjus & Antuchevičienė, 2013). Temporary facilities for the personnel working at the site have to be developed at the site. A temporary office as well as store is also required. Some of the construction materials such as cement has to be stored in doors and hence the need for a store room. A holding yard is required at the site where all the trucks fetching the materials will be stationed. The site also needs to be fenced off as part of the preparation process. Proper signage has to be placed at the site so as to guide the personnel who will be working or visiting the site. Clearing of the site has to be carried out as part of the preparation process. The services such as water and electricity have to be located at the site before the construction process begins. Site preparation activities are useful in ensuring that the works can commence immediately all the equipment and materials are on site (Dėjus & Antuchevičienė, 2013). It is also useful in ensuring that some of the likely problems are detected early and avoided. All the structures at the site should however be temporary as the site has to be cleared once the works has been completed. Key activities that needs to be completed No Activities Details 1 Site layout Making preparation for the work site. 2 Marking the site Taking measurements and marking the areas that need to be excavated. 3 Excavation Digging the foundation in order to lay the ground works for the drainage. The excavation has to be carried out to the required depth. 4 Blinding Doe on the surface in order to correct irregularities based on the levels of the bed. It ensures that a smooth and level surface is provided for placing of concrete. The thickness of the blinding is about 50mm. 4 Laying of concrete and reinforcements Placing of the concrete after the reinforcement has been correctly tied. This process is vital in terms of the development of the drainage. 5 Laying of pipes and backfilling Laying the correct sizes of pipes and ensuring they are backfilled properly and to the required standards. 6 Waste disposal Disposing all the solid wastes generated during the construction process and clearing the site after the works have been completed. Relevant Authorities Different authorities have to be involved in the project in order to meet all the standards as well as safety requirements. Worksafe Victoria is one of the agencies that should be involved in the project. It plays an important role in terms of promoting workplace health and safety. This is for the purposes of reducing personal injuries and the commercial effects that the injuries have on the workplace. This authority will play a vital role in the project by providing the guidelines as well as the measures necessary to promote safety. The agency will also be involved in frequent inspections to ensure that the workplace is safe at all times. In order to ensure that the environmental protection efforts are effective, Environmental Protection Authority (Victoria) has to be involved in the project. The role of the agency is to ensure prevention of harmful effects caused by pollution of environment. It is also involved in responding to environmental pollution problems (Sweet, et al, 2012). It can therefore play a vital role in providing expert advice to the project in order to prevent environmental pollution. This is considering that the risk register indicates that environmental pollution is likely to take place during the implementation of the project. Environmental Protection Authority (Victoria) is also involved in monitoring the sites so as to establish compliance with the regulations. The agencies have highly qualified personnel in the field of safety and environment. The project will therefore benefit from a close working relation with the agencies. Acts have also been established in order to promote safety environmental protection during the construction process. The Occupational Health and Safety Act 2004 (Vic) has to be complied with during the implementation of the project (Sweet, et al, 2012). The Act is provides guidelines regarding the issues of safety as well s health when carrying out different construction activities. The roles and responsibilities of the key stakeholders have also been highlighted in the Act. The provisions of the Planning and Environment Act 1987 must also be complied with during the construction process. The Act mainly provides information concerning the environmental protection activities during the construction process. The rules and regulations that are in place are mainly aimed at reinforcing the work of the different agencies. National Construction Code is one of the regulations that has been put in place to govern the construction activities in Victoria. This regulation incorporates all the onsite building and plumbing requirements into a single code (Sweet, et al, 2012). The regulation is relevant to the project as some plumbing works will also be carried out during the construction process. In order for the stakeholders to obtain more information about the risks as well as the constriction processes, Fair Work Building and Construction agency can be consulted.
