Offsite construction is the most efficient alternative to conventional methods and hence the government of U.K has adopted various offsite methods of construction since the twentieth century due to the increased housing demands and limited availability of skilled labour. In spite of the various benefits offered by the offsite construction methods, the growth has been slow in the construction industry. This research will focus on the various offsite construction techniques currently being used in the housing sector and various solutions to overcome the barriers that obstruct the growth of offsite construction in the housing sector. A survey questionnaire was set and send to various different professionals working in the construction industry such as contractors, designers and house builders in order to analysing the current situation of offsite construction in the housing sector. The wider usage of offsite construction techniques are inhibited by the high investment costs, delayed time, interfacing problem and delayed planning process. The current usage level of offsite construction techniques in the U.K housing sector is low compared to other countries. Based on the research findings, various recommendations and strategies have been put forward in order to gain visibility and credibility, of the offsite methods of construction in the housing sector.
Introduction:
Offsite construction technology involves making use of pre-fabricated components that has been manufactured in a
Bolted steel construction: this is when the main bulk of the construction is pre made at the workshop then bolted into place on site. This tends to be the preferred methods as it saves time and money as well having the right working conditions.
Any elements of the existing structure that have new and altered loads are to be exposed
The major political influences on the construction industry in London at the moment are the Mayor of London’s Sustainable Design and Construction Supplementary Planning Guidance to the London Plan, the Climate Change Action Plan, and the Governments lack of response to the effects of the recession. The recession has almost completely stopped the building of new houses and has led to the mothballing of most of the
Construction projects contain a high level of complicated procurement processes. Not only the revenue or profit is critical in the construction industry, but market intelligence and construction procurement knowledge are also important. The bidding process in the construction industry is illustrated by many different involved parties including the architectural and engineering firms, client, general contractors, material suppliers, specialized contractors, manufacturers, etc. (Halaris, 2001). Preparing proposed documents, appraising bids, and awarding the contract to the winner of the bid are among the major duties of the client (Gokhan et al, 2006).
Procurement activities and choices constantly evolve as the needs to ensure construction project successful is eminent. According to JCT (2011), procurement refers to a generic term that embraces all relevant activities undertaken by a client to implement a construction or refurbishment project. It is important that the basic principles such as selection process, the relationship between the client and contractors, responsibilities and management are always there. As a private developer in Chelmsford wanting to pursue in making sure a successful completion of building a new food store with 37 residential units with flexible floor space and associated car parking facility, it is important that the contract placed ensures it covers every aspect of necessity for the successful project completion.
This is an ever-increasing issue, which threatens us to cause housing problems in the near future. That is why there are a numerous number of firms in the construction industry engaging themselves in erecting and repairing building, roads, houses, bridges, dams and much more. This capital good industry is a source of heavy units, which are immobile and quite expensive.
Nowadays, the growth of construction industry’s productivity is slow, unlike the manufacturing sector, where standardization of components, mechanisation and innovation greatly enhance the rate of production, that is because of the procedure of construction industry is more complicate and always take longer time than manufacturing sector. Therefore, the supply to meet the needs and demand of housing and infrastructure is a very slow process.
The construction industry plays an integral role in the economies by providing infrastructure to all other industries. This report discusses the factors that are pertinent to establishing construction operations in the European market, with a main focus on Prime Constructions Company Ltd. The assessment of the markets is discussed with an entry mode proposed. Moreover, the supply chain the company would need to adopt as well as the innovation strategies and risks therein are also discussed.
An effective procurement plan and policy should set clear state roles and responsibilities, avoiding ambiguity and presenting a consistent framework for the council and its partners to work in (Chartered Institute of Procurement and Supply (CIPS) 2014). A procurement strategy should also take account of CBC’s need for projects delivered on time and within budget. The strategy aims to highlight the need for quality and sustainable development. The method of procurement depends on CBC’s need to be involved in the design process in new projects and the degree of certainty required with respect to cost of these works. For example there is a greater certainty of time and cost associated with the design and build form of procurement than with construction management or the traditional form of procurement. However CBC would have greater input in the design with the later forms of procurement than with the design and build option (Constructing Excellence 2004).
Table 4.1 shows the number of questionnaires distributed to and retrieved from the selected contractors. Copies of the questionnaire were distributed to some of the professionals who in full capacity are engaged in one form of construction project or the other. The reason for this was to get a direct feedback as pertaining to the accomplishment of the set objectives outlined in this research. At the end of the exercise, 25 out of 30 Civil engineers (representing 83.3%), 6 out of 6 Architects, and 14 out of 14 Builders filled and returned the questionnaire. In total, 90.0% of the total questionnaire distributed where retrieved and this was accomplished by the personal efforts of the researcher.
Typically, in the construction industry many resources are drawn into a complex building project. Clients, financiers, government, architects, engineers, project managers, consultants and other stakeholders each play a part in producing the end product. However, their interests are varied and can be at cross-purposes. This typically results in a fractured and disjointed approach to building.
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
In order to build a certain structure, construction materials will be needed to create a beautiful structure that will improve the nature and references of a certain structure. In this position, the construction of a facility enables individuals to improve their welfare, as well as their position to promote the advantage of accomplished structural developments that will ensure the structure becomes reliable. This includes cement, metal frames, glass, glass fibers, metal sheets, sand, gravel, rocks, paint, nails, hammer, excavator, wood, plastic, metal tubes, wires,
Every function of the construction industry is being influenced by technological advancement and more activities in a construction project are now aided by a software. Emerging technologies like Building Information Modelling (BIM), Cloud Computing, Mobile Computing and others have enabled the industry to not only improve tremendously in terms of productivity, but also in terms of quality through better coordination among multiple project participants, Training, Visualization and clash detection (Ahmad et al. 1995). Moreover, it is the adoption of these technologies and the relative skills of contractors in these that
The precast structural components are manufactured off or on the sites, transported to the site and with suitable handling and erection procedures, they are assembled so as to form a structural system. The design should cater to the conditions encountered during the various stages of construction. The Different types of precast elements manufactured are listed below.
