THE INFLUENCE OF CONSTRUCTION METHOD ON PROJECT SUSTAINABILITY

THE INFLUENCE OF CONSTRUCTION METHOD ON PROJECT SUSTAINABILITY

Project Specification

Climate change has increasingly affected the environment over the past years due to human activities especially with the increase in greenhouse gases. Rise in the amount of greenhouse gases is as a result of increase in use of fossil fuel such as diesel. On construction site pollution has been a challenge and a topic of the day with the aim of developing mitigation measures. The effects of these associated pollution is the climate change which is hazardous at some extent endangering the lives of environmental constituents.

For our scenario, we want to design mitigation measures of reducing pollution on a project construction of Empire Theatre. The theatre is constructed near a river hence there is high groundwater table. The soil structure of the site less compact due to groundwater level and this requires a substantial foundation e.g. pile foundation. According to our scenario, we intend to address solutions to pollution and climate change in construction industry as per sustainability requirements.

The pollutions we are addressing through our scenario include the air pollution which is influenced by dust and emissions from vehicles and other machinery. Dusts from cement, concrete and stones put the workers at the risk of infections. Use of diesel in vehicles and other mechanical equipment increase emissions of carbon dioxide, carbon monoxide and nitrogen oxides which are greenhouse gases. Increase in these emissions increase global warming which is a global problem under debate for meeting sustainability. Discharges from construction sites such as solvents, paints and used oil are main sources of water pollution. Construction debris also cause water pollution when they spill to the near water bodies like rivers for our case. Also when clearing land, silt-bearing may occur as a result of soil erosion and these may lead to destruction of aquatic life through formation of turbid. The water run-offs within and around the site increases the amount of pollutants such as oil spills and wastes from building materials carried into the river.

For the case of our project scenario, solutions to these problems (pollution) includes replacement of concrete cement with less concrete steel to reduce the amount of dust discharged from the construction site. Construction materials such as plastics should be recycled to reduce debris and dirt. Construction operations should be timely and sequential to reduce impacts on environment and increase productivity of the project.

Various researchers have been done on the possible causes and impacts of pollution and climate change from construction site on sustainable development. Most of the construction industry has set sustainability policies to fight against pollution and mitigation measures. Energy performance in construction industry and mitigation measures of carbon dioxide has been related through carrying out counterfactual analysis. Other industries have developed recycling sites to recycle materials from construction site e.g. in residential buildings gases emitted are recycled and use of alternative materials. Industries have enhanced sustainability through use of less material such as less concrete in designing buildings in order to save on cost and reduce pollution. Besides, application of natural light in energy provision and inert heating and cooling reduces the amount of energy used at a time.

New technologies have been incorporated in construction industry to reduce pollution and climate change. Passive house technology have been embraced on building design through integration of excellent insulation, air-tight construction and proper ventilation. While ensuring sustainability, advanced technologies strategies on energy integration have been incorporated in construction design while considering life cycle with the aim of reducing pollution and climate change.

There are standard approaches which can be used alternatively in ensuring sustainability while reducing pollution and climate change. For instance, the cost of the bulldozers and excavators varies and therefore, nurturing local machines and materials can upgrade the system of work. Highly skilled personnel are required for precise and highly good construction details as far as passive house technology is concerned thus however need local workers as an area of focused.

Project Management Plan

For the success of Empire Theatre construction, a management plan has been designed to explain the types of resources and resource planning, work plan, cost planning, project progress. Provided is a log book showing the breakdown of the management plan on the theatre project. While executing the management, the effect of pollution from the construction site is considered with incorporation using less concrete and steel. The progress of the project will be administered by the project manager who will be communicating the progress regularly and when need be.

Research on impacts of concrete on climate change shows that the concrete itself is not bad but because of the much we use. Technologies haven’t had ways to change sustainability of concrete and the only way to reduce impacts on the environment is to reduce the amount we consume and production. However much we consider recycling concrete, it is no doubt that the technique will not qualify since they are much demolished concrete.

Project PERT Analysis

Data

Looking at the table above one can conclude that concrete have no impact on the climate but the truth is that it affects sustainability of the environment. Using less concrete and steel will reduce the amount of CO₂ hence reducing the effect on climate. However, recycling concrete on construction has less impact on reducing global warming.

In construction industry, concrete and steel are the most essential materials for construction. Annually, approximately 20 million tonnes concrete and 2000 million tonnes of steel are manufactured and produce about 5% emissions of CO₂ globally. This percentage emission contributes to the global warming which poses risks to peoples’ lives and environment.

Potential Project Management Solutions

Solution is a key attention prior to curbing the industrial waste pollution, climate change to keep the environment clean, conducive for living and free from poisonous gases. Some of the waste produced in the course of construction can be eradicated. For instance, modular durable metal for use in concrete construction might be carefully chosen on the basis of being readily demounted and be reused on other projects, hence eradicating wood waste related with formwork made up of plywood and lumber dimensions . Abolition of waste is helpful in reducing influences on human health and the surrounding environment at large.

Some of these materials can be reused. For instance, windows and doors in good, can be resale for condition may be eliminated for new products, or be provided or sold for use on another project for reuse.

Waste that was generated in the construction process can be eradicated that is for example, modular and durable meta that form hierarchy for use in construction of concrete may be chosen on the basis of being readily and demountable for reuse on other areas of projects, thus eradicating wood that might be waste in association with form of work made-up of plywood and lumber dimensions. Eradication of these wastes can only be helpful to reduce effective on health of human and its environment

Industrial manufacturers on carrying out recycling tend to invest in developing of improved machineries which have potential to transform the efficient arrangement and distraction of waste.  Shredders in industries tend to reduce corporal volume and produce elements of constant measurement, allowing effective separation of mechanics. Separation of industrial air technology allows effective separation of materials with contrary characteristics of mass, therefore separating small pieces of wood and plastics from metals and aggregate.

Some of the building-related with waste can be brought to minimal. For example, products of constructions can be chosen on the basis of how it can be designed and manufactured so as to be shipped with minimizing packaging. Also basing on that selection and using of recyclable materials and products gives a potential to reduce waste.

Management of local practices and dumping of construction and destruction wastes frequently are made by the availability of appropriate disposal sites, economic conditions, priorities of the societies, markets for recycling and reusing, transport options, and the capabilities of local personnel and businesses constructions to adapt destruction processes for wastes management.

Construction management and destruction of wastes is addressed at project, organization, and at levels of disposition.
