Sources of literature refer to prefabrication, off-site construction, pre-assembly and modularisation concepts either respectively or collectively, (Haas et al., 2000).
Prefabrication -Haas et al (2000), prefabrication normally involves a single skill or trade, such as electrical, or piping, and this can be defined as “a manufacturing process, which generally takes place at a specialized facility, in which various materials are joined to form a component part of a final installation” (Tatum et al., 1987). Components manufactured off-site and is not a complete system can be referred to as prefabricated components. Furthermore Jaillon & Poon (2009) proceed to describe prefabrication as, a manufacturing process, commonly conducted at a specific facility, in which numerous materials are combined to form a component which is part of a final installation. The manufacturing process may be undertaken in different environments such as, a factory environment (factory prefabrication) or (site-prefabrication) on site under the open sky. The term off-site fabrication is utilized when prefabrication and pre-assembly is integrated (Jaillon & Poon, 2009). Gibb (1999) defines off-site prefabrication as a process which integrates prefabrication and pre-assembly. This process includes the design and the manufacture of units or modules, typically away from the work site, and their installation. “Off-site fabrication requires a project strategy that will change the orientation of the project process from construction to manufacture and installation”, (Gibb, 1999). (Klerk, 2013)
Modularisation – is generally referred to as the preconstruction of a complete system away from the job site which is then transported to site. The modules are large in size a...

...fsite the construction activities can be broken up and completed simultaneously at various locations hence shortening the construction duration by the dispersing the work (Haas, O’Connor, Tucker, Eickmann, Fagerlund, 2000).
Disadvantages of prefabrication-
There are also several disadvantages and impacts to the use of prefabrication (prework). Transportation costs can be an issue due to offsite work (CII 1992). This is particularly true for large modularized sections that must need to be transported over long distances. Secondly, size constraints and limitations exist due method of travel, which directly leads to cost and schedule considerations. Thirdly, a need for increased engineering effort upfront (CII 1992) meaning that design work and extensive planning prior must be completed before prework can begin. (Haas, O’Connor, Tucker, Eickmann, Fagerlund, 2000).
Six flags is a company that has 29 theme parks with a Chief Corporate Engineer, Larry Chickola. Larry overseas all the projects for the parks and has teams of engineers that help take care of technical issues and building and construction. All six flags projects have a comprehensive plan for completing the work in a timely fashion. They have written statements as to what work is to be done and dated schedules for completion. They also have to include tasks and sub tasks all being figured into the budget. There is a “work package,” which is a group of activities assigned to break down each task and sub task to fit these into manageable quotas. They feel this is the key to managing logistics.
Purchasing a kit plane and building it is something that is easier than a person would expect. After one orders a kit plane, it comes “Where initial shaping of the metal is done by the manufacturer but all assembly is done by the owner” (manufacturing process). This is so the owner is able to successfully complete the plane without having to worry about the shaping and molding of metal sheets to form the airplane body. Building an airplane has become pretty simple, and over time, Stewart McDougall documented his steps in building a kit plane and according to him, “The equipment used in the assembly was a mixture of hand tools and some machines such as belt sanders” (manufacturing process). This just proves how kit airplanes are something that is always being made easier to build and create. Building a plane requires lots of man hours and work “work for assembly was at about 540 man-hours” (manufacturing process). Even though that seems like a lot, i...
Prevost designs and manufactures its own commercial bus chassis and body structures that are among the strongest and safest in the industry. Prevost builds chassis and luxury coach shells and provides these high-end shells to converter partners that complete the final interior build to the end customer’s personal design specifications (Buses and More, 2014). Prevost has its own supply chain in place for building and producing its chassis and luxury coach shells. Prevost is also part of numerous other companies supply chains as its chassis and shells are the necessary components for its partners who specialize in taking these chassis and shells and creating the high-end finished luxury coaches seen on the market today.
Focus shall be on utilizing pre-production tools while developing the prototypes. Actual material, wherever possible, shall be used in the development of prototypes rather than having substituted parts. Make the prototypes as closer as possible to actual outputs.
There may be a centralised workshop that machine-tools spare parts, maintains equipment and vehicles, etc. Or workshops may be located near various operations.
The film, “My Big Fat Greek Wedding”, follows the character Toula Portokalos, a Greek woman living in Chicago with her Greek family. She is still unmarried at 30 years old, the opposite of what her father wants. She eventually finds a job at the travel agency her aunt owns, where she later finds and falls in love with a non-Greek man named Ian. Knowing her father would not approve of this, she goes forth with it anyway. Throughout the movie, Ian moves into the Greek culture and eventually becomes closer to the family.
The idea is that the designer first establishes rules and relations by which design components are connected to minimize the time and effort consumed in modifications, and to provide multiple solutions that could not be reachable by traditional methods. The parametric approach has been studied and analyzed by numerous academics and designers (Araya, S., 2006, pp.11-12; Gane, V., 2004, p.54; Hudson, R., 2008, pp.18-19; Llabres, E. and Rico, E., 2016). Most of them coincide describing it as a series of phases, which increase in the level of detail and precision, as they involve from preliminary concept to construction. Herein, the parametric design process starts with Design Exploration, in which background data and design problems are determined, including the design objectives, variables, and constraints. The second phase, Design Development, includes possible solutions for design problems and manipulations of design instances. Generation of alternative solutions are reviewed and evaluated in the Simulation / Evaluation phase, to satisfy project goals, and previously built constraints. After these explorations, a development is considered one single direction in the Manufacturing / Construction phase (Araya, S., 2006, p.12; Gane, V., 2004,
Anybody and everybody can become an industrial machinery mechanic; especially, those who are passionate about getting their hands plastered in motor oil, grease, and other mechanical lubricants. These people will more than likely be ecstatic about getting into industrial machinery mechanics. They need to be able to put in one hundred ten percent of their effort into becoming an industrial machinery mechanic. An industrial machinery mechanic’s overall objective on the job is to stop a mechanical error before it happens. An industrial machinery mechanics are often caught repairing, maintaining, and fabricating machinery. They will be required to have certain education and training as well as some on the job training or complete an apprenticeship program. They will receive many benefits for working in this particular field.

Management individuals successfully in expansion projects are an ability that requires consistent arranging and improvement. Like in the case of the construction management, a lot is required of a person to ensure that the best is achieved in the general outcome of the task at any given level. An augmentation program director can be characterized as the individual who is vested with formal power over an association or one of its sub units. He or she has status that prompts to different interpersonal relations, and from this comes access to data.
