Engineering and Construction Essays

The development staging involves the process of informing the relevant authorities. Upon approvals of the master plan, the construction and engineers responsible for executing the planning prepare the budgets and the costs involved in the whole planning process. The framework for the planning and expansion of the airport is laid down.

Firstly A380 has grown tremendously since its inception in 2007. It provides high reliability and high comfort. It also exists as a double deck carrier capable of carrying over 500 people as well as three classes that has a capacity of carrying over 800 passengers as stipulated by Norris (2005).

Stress develops beneath the surface of the Earth for a considerably long time, which eventually erupts causing an Earthquake. The shaking may last for hours or weeks depending on its magnitude.

Air compressors can be used for quick inflation purposes because they release pressurized air. Such products come with built-in mechanical capabilities that can be used to inflate various objects such as kayaks, inflatable canoes, rafts, and tubes inside tires. Compressors are also widely used in the auto industry.

A successful CM chooses the right people for particular tasks assigned to them. This stimulates accountability and transparency. CMs can effectively motivate team members to finish tasks within the allotted period. It is the responsibility of CMs to count every team member as part of the successful crew.

Ethics require that an engineer be familiar with the engineering principles as they try to give facts and opinions to consumers. Deceiving a client into purchasing a given machine is a serious offense. The above three qualities are what holds value in engineering. Ethics also require that engineers explain the defects of a product.

Where; Ø = is the porosity p = is the pore volume of the reservoir rocks B = is the bulk volume of the reservoir rock (Ketzer and De Ros, 2012)However, porosity does not offer information regarding the distribution of pores, their sizes as well as their connectivity level. Therefore sedimentary rocks having similar porosities are capable of having physical properties that are very different.

Aluminum casting alloys manufacturing has diverse implications all over the world both in the economy and the environment either negative or positive. For instance, increased demand for secondary aluminum has to lead to the general reduction of environmental degradation thus ensuring environmental sustainability.

Cast iron is suitable for developing ornamental designs on different structures because of its malleability. It can be twisted into different shapes which can be used to draw different figures which makes a structure more visually appealing. Cast iron is also used to insulate electric cables in different structures to enhance safety.

Cast IronCast iron is one of the ferrous metals that have a wide range of properties produced through the process of casting. Cast iron has a crystalline structure and good compressive strength. However, it is very brittle and weak in tension. In addition, cast iron has excellent fluidity when molten, hence it is used for the production of intricate shapes (Tata Steel, 2013a).

Over the years, Mott MacDonald has emerged to be one of the largest companies owned by employees. The company has over 14,000 employees and has principal operations in about 50 countries. The company also has around 140 projects around the globe (Mott MacDonald 2013, p.1).

Fire investigative responsibilities are considered as one of the legal and scientific trends of forensic science transformations. Today, fire is considered a science subject, albeit in criminal prosecutions the perceptions about fire have resulted in misunderstandings about arson (Strutin 2012).

The initial stage of a fire-fighting operation involves an examination to determine the cause of the fire and establish fire-associated risks and victims. During training, firefighters are equipped with fire suppression tactics. They are supposed to establish the signs of fire in case of a fire outbreak before embarking on the extinguishing process

For this particular design, the earth pressure coefficient, KoKo = 0.33/ (1-0.33) = 0.49Section of the reinforced retaining wall friction angle and cohesion and friction angle used in the design of the retaining wall are regarded as constants. These constants provide a description of soil properties.

Smoldering was linked with the cause of the fire. However, the smoldering process occurs as flameless combustion, which happens at very low concentrations of oxygen and continues at a very sluggish rate. A common illustration of smoldering fire is a burning cigarette. The heat from such a source normally chars the adjacent tobacco.

The next item that will be focused on in this paper is that involving the discussion of the different types of modeling that can be applied in fire investigation. Under this item, such models as the numerical models will be highlighted. These kinds of models are those that involve the use of mathematical calculations because of the presence of numbers. The other kind of model to be highlighted is the full-scale building model.

A mistake in application is another limitation of the computer fire models. A model user or fire investigator can make an error while putting input into a fire model or while analyzing the output due to several reasons. Some of the reasons that might contribute to such errors include a slip in reading output or inserting input.

Still, in controlling machines, it is used in equipment such as bulldozers, graders, and excavators in an effort to provide productivity in the real-time operation of the machine. More also, it provides information and situational awareness of the person operating. The adoption of machines that are GNSS-based control is similar to the initial hydraulic technology which is used in machinery that exhibits profound reliability and productivity.

During the design stage, robotic total stations are used together with building information modeling to generate various types of data that are paramount in the design. This includes distance measurement, checking of boundary properties, making layouts for excavation designs, setting control points, as-built checks, topographical measurements.

Arch, suspension, and truss bridgesMay 2014Introduction Bridges are important structures that serve to overcome barriers that hinder movement from one point to another. The bridges are used in connecting two regions separated by a river or may be used to connect an island to the mainland. This report looks at three types of bridges: arch bridge, suspension bridge and truss bridge.

Surveyors today have a lot of data and information to manage while facing escalating demands of first-class topographic inventions such as construction site surveys, land possession. One of the most vital tools surveyors make use of is the robotic total station which has been used for decades simply for the storage of examination materials.

The piston engines also produce a lot of noise. For instance, the piston aircraft engines have a maximum speed ranging from 2,500 to 3,000 rpm. The propeller may, however, be inefficient and generate much noise at this rotational speed. Due to this drawback, piston engines typically have a step-down ratio of between 0.5 and 0.7.

There are different types of HVPD signals that cause different degrees of damages to particular electrical equipment. Some of these signals include the power-line system carrier communication noise, rotating machine commutator noise, corona discharge noise, colored noise, and electric appliances switching circuit noise, among others.

When designing the SCADA system for an ethylene cracker gas plant, an appropriate platform is chosen to support different features. A resolution of 1280 by 800 is appropriate for the gas plant and is usually considered during the design. The resolution is readily available in the market and hence making the design process easy.

The “Modbus ASCII” unlike the other two can be regarded as being the first Modbus which is also still a serial protocol and which runs typically on either the “RS-485” Physical layer or the “RS-232” physical layer. The Modbus ASCII frame is known to be about 252 bytes in its length and it is also capable of having a total of about 247 addresses.

This project consists of designing a module for a single-phase induction generator to interface with the existing H-bridge and enhance its functionality. This design will feature various inertial, position switches and utilize variable frequency drive (VFD) with the motor.

The Chulha stove was found to put the exposure to smoke to minimal by virtue of it having a chamber that channels the smoke out through a chimney. The design plans are available for free for modification as the design is open-source. The material for use in the construction of this stove is readily available locally although the cost of producing the stove was found to be quite high.

Design engineering is a discipline in engineering that develop new products and processes with the aim of adding value to a function. It has provided me with information for analyzing, evaluating tasks, and achieving course objectives this semester. Design engineering has provided a platform for me to broaden my knowledge and learn new skills.

Fire can be seen as being a hazard in the building and in the whole institution. Fire when it strikes would result in a number of consequences that include threatening of life or health and safety of occupants, would cause damage, or result to a total loss of property and normal business activities and opportunities being interrupted in the building.

The refugee areas are also to have emergency voice communication (EVC) that will ensure effectiveness in the evacuation of the disabled from these areas. The installation of an EVC system should be in line with BS 5839-9:2003 that includes Type B outstation with a communication link to the master station located at the fire alarm panel.

The alarming rate at which oil fields are drying up has made the extraction method a critical aspect as far as oil exploration is concerned. Apparently, as Owen, Inderwildi and King (2010) note, even though it might seem abundant in some regions, there are growing demands to minimize waste because oil is not a readily renewable resource.

A humidifier as such comes in handy when the humidity levels of a room are below the minimum tolerable levels. The humidifier works by raising the levels of moisture in the air. A dehumidifier, on the other hand, is the reversal of the humidifier. It performs its duty by eliminating or decreasing the saturation of moisture in the air.

They allow fresh air and light to pass through into the home interior and also provide a view connecting the home’s interior with the outdoors. Despite this advantage, windows if allowed can be a primary source for undesired heat gains in areas experiencing summer and a major source of heat loss during winter.

The use of 3D printing reduces the need for some professionals involved in the construction process under the traditional process. The use of 3D printing during the construction process effectively ensures that a high number of roles are reduced. Reducing the number of employees means that labour costs are drastically reduced.

In the course of this year, I had an opportunity to exercise the set of theory lecturers I learned to real-life scenarios. I managed to apply and secure an internship with one of the most sought-after companies in the area: Guangxi Huala Design and Consulting Group Co. Ltd which is headquartered in Nanning.

There are other several engineering equipment found in ICU such as patient monitoring machines and pacemakers. This essay only focuses on three main types of equipment. The pacemakers, the tube feeding, and the physiological monitoring machines will be discussed as the main engineering equipment used in the intensive care unit.

For the purposes of fighting a fire in the shafts of a building, ADB recommends that a provision of fire mains should be of essence (ADB, par 15.2). For academic buildings, the case may differ slightly since the firefighting shafts are the least of requirements (section 10.4).

Process control is a system in engineering dealing with constructions, techniques, and algorithmic programs that are utilized in the maintenance of the output of a given process within a scope that is desirable.  Controlling the temperature of chemical reactors is an example of process control aimed at maintaining the consistency of the production of products.

Green roofing and reusing of the collected stormwater in the building can be applied in the Melbourne CBD. The green roofing can be applied to ensure efficiency in the use of energy by reducing winter heating costs and the costs used in cooling during summer through ensuring insulation of the buildings to reduce heat loss.

Generally, planning enhances communities and people’s overall well-being through the creation of more attractive, equitable, accessible, healthy, and efficient places to work, live, play and plan. Effective planning can as well create communities that provide improved choices for how and where people live and ensure that future generations are offered fair and realistic opportunities.

Attempts to make the industry thrive have failed and even the remaining manufacturers such as General Motors Holden, Toyota, and Ford have since announced their exit by the end of 2017 [2]. While some market analysts argued that it was the trade unions, which caused the demise of this industry, others think otherwise.

Among the Middle East countries, KSA is the fastest-growing state in power consumption. In 2005, KSA was among the top 15 economies in consumption of primary energy, 60% of the energy came from petroleum, and 40% was natural gas. Electricity in KSA is under the ministry of oil and the Ministry of Water and Electricity.

Union activity prevented the industry from being more innovative hence competitive. According to, this problem was especially noted by Nissan’s management, which was always worried that unions pushed for restrictive and outdated work practices hence limiting flexibility. Bolt also observes that union militancy triggered the exit of Toyota.

Elimination of protectionism, fluctuations in currency and industrial relations-unions, unions contributed a great deal to the closure because in having a hand in every factor mentioned. In conclusion, there is a substantive argument to conclude that unions played a key role in the closure of the firms in the Australian automotive industry.

It is discovered that with partitive mixing and different designing one can arrive at a number of selections, and there are both, the positive and negative impacts of this. The positive will be that it provides for a number of choices and perceptions that can be interpreted and represented, but the negative side is that it can be very confusing.

The identification of the constraints in the construction and safety of the building are constructive factors at all the stages of the construction process starting from the planning stage through the execution of the plan with all its micro details and subsequently, residential or commercial utilization of the building.

In most cases, this involves the modeling or calculation of scenarios that address all or several parts of the fire system. Using the same principle, this assessment bases its assumption on the premise that designing the protected routes is dependent on the designated use of the building and the risks of fire inherent in that particular use.

Fire resistance testing is aimed at determining the ability to build construction to withstand a given temperature when exposed to fire at a given time and specific pressure and retains its fire separating functions.  The test may be carried out on some of the building parts such as the walls, ceiling, columns, beams, and doors.

Fire resistance is the ability of an element of load-bearing structures in construction. Therefore, tests carried out on these elements of construction or structure and building materials to ascertain their abilities to meet the minimum threshold required for fire resistance capabilities is known as fire resistance testing.

Sir Tom Finney Sports Centre aims to see to it that all students, university staff, and visitors who use the facility are safe from risks of fire. The sports center upholds fire safety procedures and systems to protect the sports facility, its occupants and to ensure that the fire systems are well monitored and maintained in compliance with the requirements.
