In complex environments such as the constructionindustry, which encompasses a productive chain with diverse sectors, and where several performers simultaneously carry out multiple interconnected activities, often errors, omissions and misunderstandings are committed, resulting in undesirable outputs that must be reworked (Hegazy et al., 2011). Particular aspects of the civilconstructionindustry, which differentiate it from others, such as relatively long construction periods, the manufacture of unique products, the interference of a complex network of participants, the lack of monitoring of technological advances and deiciencies in the technical training of labor (Colombo & Bazzo, 2001), increase the possibility of reworking. In addition, some peculiarities of this industry in Brazil make the accuracy obtained even lower than in other countries (Fé Castro et al., 2014). The constructionindustry in Brazil has a low technological and management upgrading, as well as low levels of competitiveness and productivity, compared to developed country standards (Colombo & Bazzo, 2001; SEBRAE-MG, 2005). The sector is marked by problems regarding compliance with technical standards and standardization, as well as the intensive use of labor, and workers do not have adequate technical training (SEBRAE-MG, 2005). Such characteristics of the construction
The objective of this work is to describe educational practices on the enviroment and working conditions in the civilconstructionindustry carried out in fifteen classes of construction workers within the framework of the Integrated CivilConstruction Training (FICC) project. The FICC university extension program integrates FICC SABENDO, FICC SAUDÁVEL and FICC VERDE projects, respectively in the areas of productivity and quality; worker health and first aid; and waste management at the construction site. For that, a plan was drawn up for the realization of the workshops held with about 150 workers on the environment and working conditions in the constructionindustry. Considering the activities carried out at each meeting, it was observed that the collaborators participated in the activities proposed and demonstrated knowledge about the topics discussed.
The research investigates Miles and Snow (1978) strategic typology as the strategic choice and business performance among Class F entrepreneurs in civilconstructionindustry in Malaysia. The result concluded that Prospector strategy is the most effective strategic typology in the small constructionindustry in Malaysia whereas reactors are the lowest achievers. Analyzer and defender are the moderate class F performers. The most competitive and the destructive strategic typology have been revealed from this study. This is important to serve as a guide to those who involved or intend to be involved in the small constructionindustry in Malaysia. It is useful for strategist and businessman, especially in the small constructionindustry in Malaysia to take it as a normative theory which they might practice throughout the daily activities especially during the formation of the business strategy.
Com o objetivo de fortalecer essa integração e valorizar ainda mais a Construção Civil desses países, a ALCONPAT instituiu, em 2011, a “Comisión Temática de Procedimientos Recomendables” sob a profícua coordenação do Prof. Dr. Bernardo Tutikian. Essa Comissão tem o objetivo de levantar temas de interesse da comunidade, buscar um especialista que se disponha a pesquisar e escrever sobre o assunto, voluntariamente, e divulgar esse conhecimento na comunidade Ibero-americana.
It is interesting to observe that the Hong Kong construction firms consider their expansion to Mainland China is an action of internationalization decision. Once according to the typical defi- nition of “internationalization” of an enterprise occurs when they gain related revenue from a pro- ject outside of their home country (Lu et al. 2009). The main differences between them are due to the political, economic model, where China enjoys a communist political system and unfree eco- nomic system, whilst Hong Kong is a capitalist political system (following the same system as Brit- ish government colonial rule before the handover in 1997) with a free international open trade eco- nomic system, by benefiting the principle of “one country, two Systems” as a Special Administra- tive Region. Another observation is that Hong Kong is considered a developed country and Main- land China is seen as a developing country, with a high demand of urbanization need in various cities. Thereupon, it is valid to say that the Hong Kong construction firms do have an internationali- zation experience in Mainland China.
In Ghana, the construction and housing industry plays an immeasurable role in the national developmental agenda. What however, appears to be debatable is whether the industry wields the much expected driving force required to pronounce its vital contribution towards accelerated national growth in terms of infrastructural development. This paper assesses the extent to which Mobilization Advance Payment (MAP) contribute to the output of small scale contractors in the Tamale metropolis. Thirty (30) construction firms, fifteen (15) consultancy firms and fifteen (15) financial institutions were surveyed, and Chi- Squared (X2) test at α=0.05was run on responses using SPSS. The study revealed that 49% of key stakeholders in the constructionindustry in the Tamale metropolis see mobilization advance payment from clients as the most accessible and affordable form of construction financing. This was closely followed by Banks/Saving & Loans (regulated financial institution) with 43%, and 8% for non-regulated financial institutions. A significantly high number of consultants (60%) agreed that mobilization advance payment is the most accessible and affordable form of construction financing. The Chi-Squared (X2) Test on MAP and contractors performance also revealed an X2 statistic of ≈0.711 for a degrees of freedom of 4 which means that MAP arrangements for contractors contribute significantly to their output.

As estruturas metálicas passaram a ser utilizadas na construção civil no século XVII.O aço possibilita a realização de construções eficazes de alta qualidade, e com alto padrão estético. Utilizar o aço está associado com uma redução do tempo de serviço, e um aumento da produtividade. O objetivo deste trabalho é compreender a importância da utilização de estruturas metálicas na construção civil. A metodologia utilizada foi a revisão bibliográfica. O aço tem sido muito utilizado na construção metálica e em estruturas metálicas, entretanto no Brasil ainda se faz muito o uso de concreto, visando uma economia de materiais. As estruturas metálicas possibilitam um maior arranjo arquitetônico, de forma que tais estruturas podem substituir as estruturas convencionais. O aço estrutural é o mais utilizado nas estruturas metálicas sendo que o ASTM A-572 e o ASTM A-588 são os mais citados na literatura pesquisada.
Industrial heritage is a part of cultural heritage very much related to industrial development and its social characteristics. Unfortunately still often forgotten, it was only on the second half of the XX century that industrial heritage started to be recognized, appreciated and maintained. It may include buildings, machinery, workshops, mills, factories, mines, sites for processing and refining, warehouses, stores, places where energy is generated, transmitted and used, transport and all its infrastructure, as well as places used for social activities related to industry such as housing, religious worship or education. Most industrial heritage is from the Industrial Revolution era and on, since it was the period of time with the more and most challenging technological changes and evolutions. It characterizes a whole society, including economic, social and urban development.
between the years 1955 and 1970, was characterized by deliberate government action to promote the Buildings Sector, through the creation of the National Housing Bank in 1964, supported by a system of public savings that provided the necessary resources to meet the demand for residential housing. This initiative took place in parallel to the Goals Program, which was intended to promote the Heavy Constructionindustry, evidenced by constructions such as the Rio-Niteroi Bridge and theTrans-Amazon Highway. In this way it was possible to achieve other government's objectives such as offering working opportunities for the contingent of migrant and unqualified workers that moved from the countryside to the cities. In this moment emerged SENAI (public agency to provide skilling for workers in industry). Nevertheless, despite all the efforts, SENAI was unable to meet the need for training of such a large number of professionals in the required period (FARAH, 1996, THOMAZ, 2001; RIBEIRO; PINTO; STARLING, 2002).
Virtual reality is an exciting innovation slowly being implemented into the constructionindustry. Virtual reality or VR is “a computer generated simulation of three-dimensional (3D) environment, in which the user is able to both view and manipulate the contents of that environment” . It has many applications that can benefit a project with increased jobsite education and safety, design improvement and communication with involved parties from the owner down to the laborer, and help to exceed owner‟s expectations and lower project costs. VR is broken down into desktop and immersive VR categories. Desktop is displayed on computer monitors or tvs, which is known as Cave Automatic Virtual Environment or CAVE . CAVE consists of multiple monitors joined together to form a large screen that allows the user to feel a part of the virtual world Immersive virtual environment or “IVE will typically have the following features; it will surround its user, obscuring cues from the physical environment and increasing the sense of „presence‟ within the IVE; provide a three-dimensional visual representation of the virtual environment; track the user‟s location and orientation and update the virtual scene to match the user‟s movements, and give the user some degree of control over the objects in it”. There is great potential for improving all parts of the construction process by implementing this technology.
reduce prices for their products. However they must be conident that their products will generate proits on the ongoing basis. Authorities responsible for pricing management must help construction organizations to identify their reserves and excessive production expenses to help these companies to cut their prices. These efforts will reduce the inla- tion to the level needed to resolve the problem of affordable prices for building products. The Russian economy must be based on innovative grounds. Control over the economic concentration is an effective action. It’s used to prevent monopolization in the construc- tion market.
In any industry, the risks of a tasks derives from the hazards associated with the tasks - due to materials, equipment’s, work organization and other workplace conditions - that a worker has to face, when he or she performs the job. For instance, a mason has to climb ladders, work on scaffolds, carry bricks, use tools or be in the neighborhood of cranes. However, knowing/identifying the main potential hazards is not sufficient to derive risk reduction strategies later on. Whether or not a particular activity – such as using a chain saw – is particularly dangerous does not make it a high priority item in itself. The diverse contributions to the overall risk of a task is also determined by the worker´ exposure to the whole set of hazards (Ale et al., 2008). A large number of different RAOS methods are available for industrial processes (see descriptions on Rouvroye and Bliek, 2002 and Tixier et al., 2002). Usually three main steps are identified when performing a RAOS study: 1) identification of potential hazards; 2) assessment of the risks and; 3) hierarchy of risks. RAOS methods can be ranked from simple, comprising only one step, to more complex methods when they involve all the three steps. Moreover, their output data can be qualitative, such as recommendations, or quantitative in the form of an index of risk level.
The constructionindustry is a leader of Russia’s economy, and each citizen of our country may be justiiably proud of it. This industry is capable of suppressing the ill fame of the “natural resources anathema” associated with the Russian economy. The construc- tion industry is a blend of hi-tech methods employed in the manufacturing of materials, erection of sophisticated engineering facilities, technologies designated for long-term planning and project management, control over sizeable teams of employees. This industry urges for perfectly designed and impeccable inancial lows, thorough business calcula- tions, mature legal solutions and technologies designated for the corporate governance and interaction between the government and the society. No doubt, contributions made by designers and architects, creators of anything that is beautiful and functional, practical and great, are worth mentioning.
Proponemos un análisis de enfoques y conceptos relacionados con el mercado inmobiliario, sector inmo- biliario y, más profundamente, acerca de la “producción inmobiliaria” y la noción de los “locales como mercancías”, cuyas dos últimas nociones, con el apoyo de una bibliografía seleccionada y una perspectiva teórica crítica, basan un concepto amplio que va más allá de la noción del mercado inmobiliario. Entendemos que la discusión y el esclarecimiento de estas nociones y/o términos contribuyen a la comprensión de una perspectiva de la amplia producción del espacio urbano, así como arrojan luz sobre los procesos recientes de interés para la construcción de la ciudad. Demostraremos esa perspectiva a partir de la evolución del número de los establecimientos de actividades inmobiliarias y establecimientos y de construcción de edii- cios y obras de ingeniería civil de las ciudades de Londrina/ PR y Maringá/PR tomándolas como ejemplos empíricos constatados, y con base en los datos disponibles en la Relação Anual de Informações Sociais (RAIS) así como de la evolución de las actividades inmobiliarias de las empresas y de la construcción. Palabras clave: Mercado inmobiliario; Sector inmobiliario; Producción inmobiliaria.
Mota-Engil has been the largest Portuguese civil and public construction contractor since the merger of Mota and Engil in 2000. It was founded in 1946 by Manuel António da Mota, and in that same year a subsidiary in Angola was also created. This historical bond with the African market would turn out to be a key strength for the group in the latest years, as Europe is facing a tough recession. In Angola, ME build a privileged strategic position over 68 years, benefiting from an important alliance with the state-owned company Sonangol. Mota-Engil is nowadays present in 19 different countries around the world. International markets now represent nearly 73,5% of the turnover of the group (Figure 4), which is very notable since construction represents 87% of the entire portfolio of activities (Figure 5). The international markets for Teixeira Duarte represents nearly 81%, but in a very diversified portfolio, where construction only weights 50%.
The use of the integrated structures allows providing steady development of invest- ment and construction activity within state-private partnership, and thanks to its lexible structure it is capable to react to changes of external and internal factors quickly and ad- equately. Moreover, it is necessary to point out the possibility of using the cluster model in the process of describing functioning of integrated structures.
Niobium (Nb) was initially applied in the industry in 1933 to stabilize stainless steels against intergranular corrosion. Around 1970, niobium started to be used in many technological applications, especially in heat treatments at high temperatures, in the form of superalloys and, over the past four decades, Nb has been employed on an industrial scale. During recent years, applications of niobium have increased steadily in various segments such as: micro-alloyed steels, super alloys, thin ilms, medical implants, titanium and aluminum alloys, superconductors and copper alloys, electrolytic and ceramic capacitors. The worldwide demand for Nb grew at an annual rate of 10% between the years 2000-2010, were the sectors of energy, automotive and construction of the largest consumers FeNb. In 2000 the brazilian production was 35,458 t of Nb and, in 2007, reached 82,000 t of concentrate Nb. Brazil has the world’s largest reserves of Nb (98.53%), which totaled 842.4 million t. So, in this paper is made a study on the evolution of the production of niobium in Brazil and its main industrial and technological applications.
