This proposal has been developed in response to the request for proposals on developing solutions to an engineering problem. Water demand in Singapore uses approximately 430 million gallons a day. 45% of water usage is consumed by the domestic sector and the non-domestic sector takes up the rest. Singapore’s water supply is obtained from four water sources known as the Four National Taps. The Four National Taps consist of local water catchment, NEWater, desalinated water and Malaysia imported water. Local water catchment, NEWater and desalinated water contribute 40% of the water source, while Malaysia imported water contributes 60% of the water source. These water sources has helped with meeting the increase in water demand. According to Public Utilities Board (PUB) (2018), Singapore’s water demand is expected to double by 2060, with the non-domestic sector using about 70%. With the increase in demand of water usage, water prices are expected to increase gradually. Therefore, to kee...

In the article “4 Ways to Demolish a Building”, Rodriguez (2018) claimed that we must take into consideration several factors when planning the demolition of a building. These factors include the method of implosion, high reach arm, wrecking ball and selective demolition. Implosion is a method that comprises the use of explosives to demolish large structures. For this method to succeed, blueprints are evaluated to figure out the type, placement and time of the explosion. The next method that the author mentioned is high reach arm. The method of high reach arm is used on buildings of approximately 66 feet or higher.   High reach arm involves a base machine and demolition tool which are used to demolish and remove large structures. The author also mentioned the method of the wrecking ball is the oldest and commonly used. It requires skilful and experienced crane operators to ensure smoothness of operation. Wrecking ball demolition has its limitations as it can only be used to demol...

In the article 4 Ways to Demolish a Building, Rodriguez (2018) claims that we must take into consideration on several aspects upon demolishing of a building. Implosion comprise of explosion methods to demolish large structures. To succeed, blueprints are evaluated to figure out the type, placement and time of explosion. The author mentioned that high rich arm is used on buildings of approximately 66 feet or higher. It involves a base machine and demolition tool. These tools are used to demolish and remove large structures for certain structural materials. The author also mentions that wrecking ball is the oldest and commonly used method. It requires skilful and experienced crane operators to ensure smoothness of operation. Size of building to be demolished is limited to certain extend and such method of demolition is an environmentally friendly method. The main objective of this methods is to get back the greatest amount of materials with minimal cost involved. However, it requires man...
