Previous issue date: 2007-10-10 / The goal of this study was to investigate and analyze the civil construction
workers audiometric profile upon admission in the State of Bahia (Brazil) from
1999 to 2005. Methods: Audiometric tests (n=5702) were carried out among
male workers (age range: 18 to 72) upon admission when applying for several
job positions in 43 civil construction companies. Audiograms was classified into
three groups: normal , indicating noise-induced hearing loss (NIHL) and
other causes , and were later rated as to the presence/absence of audiometric
notches. Results: Normal hearing thresholds were found in 3949 (69.3%)
workers, 920 (16.2%) of them showed audiograms indicating NIHL, and other
alterations were found in 833 (14.6%) subjects. Although 980 (17.2%) workers
did not report noise exposure, 4722 (82.8%) subjects reported at least one year
of such exposure. The use of hearing protection devices was reported by 2483
(43.5%) subjects in contrast with 3219 (56.0%) workers who did not use it.
Workers exposed to chemicals totaled 1084 (19%) against 4618 (81%) nonexposed
ones. Audiometric notches were found in 1684 (29.5%) subjects in the
normal group, 919 (16.1%) subjects in the NIHL group and 774 (13.4%)
subjects in the other causes group. Conclusions: The prevalence of
audiometric alterations was found to be 30.7%, among which 16.1% indicated
NIHL and 14.6% were rated as other causes . Increased age, more than 5
years of noise exposure, lack of use of hearing protection devices and exposure
to chemicals were associated to the hearing losses found in the sample. The
prevalence of audiometric notches in this population was 59.3%, of which
30.9% were unilateral and 28.4% were bilateral. Besides being associated to
age, exposure time and job position, notches were more prevalent in the NIHL
group and in the other causes group / O presente estudo tem como objetivo investigar e analisar o perfil audiométrico
nos exames admissionais em trabalhadores da construção civil na Bahia, no
período de 1999 a 2005. Método: Foram avaliadas 5702 audiometria
admissionais de trabalhadores do gênero masculino, que faziam processo
seletivo em 43 empresas da construção civil. A faixa etária estava entre 18 e 72
anos. Os trabalhadores realizaram exames pré-admissonais para as mais
diversas funções da construção civil. Os audiogramas foram classificados em
três grupos: normais, sugestivos de PAIR e outras causas. Posteriormente,
também foram classificados segundo presença ou ausência de entalhe
audiométrico. Resultados: 3949 (69,3%) trabalhadores apresentaram limiares
dentro da normalidade, 920 (16,2%) apresentaram alteração sugestiva de PAIR
e 833 (14,6%) trabalhadores apresentaram outras alterações. Dentre esses,
980 (17,2%) trabalhadores não relataram exposição a ruído e 4722 (82,8%)
tinham tempo de exposição a ruído de, no mínimo, um ano. Quanto ao uso de
protetor auricular (EPI), 2483 (43,5%) faziam uso e 3219(56,%) não faziam uso.
Em relação à exposição a produtos químicos, 1084(19%) estavam expostos e
4618 (81%) não estavam expostos. O entalhe audiométrico esteve presente em
1684 (29,5%) trabalhadores do Grupo Normal, 919 (16,1%) no Grupo PAIR e
774 (13,4%) no Grupo Outros. Conclusões: A prevalência de alterações
audiométricas foi de 30,7%, sendo 16,1% sugestivas de PAIR e 14,6% de
outras causas. O aumento da idade, tempo de exposição a ruído superior a
cinco anos, não uso de protetores e exposição a produtos químicos foram
associados às perdas auditivas encontradas na população. A prevalência de
entalhe audiométrico na população foi de 59,3%, sendo 30,9% unilateral e
28,4% bilateral. Os entalhes foram associados à idade, tempo de exposição e
função exercida; além de ocorrerem mais nos Grupos PAIR e Outros

Evaluation de la sûreté de systèmes dynamiques hybrides complexes. Application aux systèmes hydrauliquesBroy, Perrine 12 March 2014 (has links) (PDF)
Ces travaux s'intéressent à l'estimation de la fiabilité des évacuateurs de crues vannés. Le comportement fiabiliste de ces systèmes hydrauliques dépend à la fois d'événements aléatoires discrets, mais aussi de l'évolution d'une variable déterministe continue : ce sont des systèmes dynamiques hybrides. Pour ces systèmes, l'événement redouté est réalisé lorsque le niveau de la retenue atteint un seuil de sûreté. La démarche de fiabilité dynamique proposée dans cette thèse vise à prendre en compte l'information temporelle, de la modélisation à la synthèse d'indicateurs fiabilistes pour l'aide à la décision et développe deux contributions : 1) L'élaboration d'une base de connaissances dédiée à la description des évacuateurs de crues en termes de fiabilité dynamique. Chaque classe de composants est décrite par un automate stochastique hybride dont les états sont les différentes phases de son fonctionnement. 2) Le suivi de la simulation de Monte Carlo, le traitement et l'analyse des "histoires" (séquence de tous les états activés et des dates d'activation) obtenues en simulation. Cela permet de construire des indicateurs de fiabilité classique (probabilité d'occurrence de l'évènement redouté, identification des coupes équivalentes prépondérantes, ...). Des indicateurs de fiabilité dynamique basés sur la classification des histoires en fonction des dates de défaillance des composants concernés et sur l'estimation de l'importance dynamique sont aussi proposés.

Um olhar sobre a questão dos resíduos da construção civil no Município do Rio de Janeiro. / A look over the question of the residues from civil construction in the city of Rio de Janeiro.Valéria Regina Asmar Lucero 19 March 2008 (has links)
Os RCC são originados dos diversos processos da construção civil, com características
bastante particulares pela variedade dos métodos construtivos empregados. Suas deposições
em locais inadequados causam vários impactos com diferentes tempos de reação e de
degradação do meio ambiente. Para impedi-los foi aprovada a Resolução 307 do CONAMA,
que estabelece critérios e normas de caráter protetor ao meio ambiente, porém as
administrações públicas possuem inúmeras dificuldades técnicas e financeiras para sua
implementação. Para auxiliar os municípios, a CEF elaborou dois manuais de orientações para
o manejo e gestão dos RCC, direcionando o sistema gestor. Uma opção para a gestão de RCC
é a reciclagem. O Município do Rio de Janeiro com seu relevo original formado por mangues
e morros, sofreu grandes aterros e sofre até os dias atuais, utilizando para isso os RCC e o
desmonte de antigos morros. Os RCC, após coletados, são destinados a uma única Área de
Transbordo e Triagem, com capacidade insuficiente para recebê-los. A ausência de controle
do órgão gestor sobre os RCC, seus dados de produção e de destinação, exige uma estimativa
dos RCC gerados no Município e uma observação global sobre seus destinos, considerando os
aterros autorizados pela SMAC. Foi realizada uma análise crítica da gestão corretiva adotada
pelo sistema gestor, suas particularidades e dificuldades, e o perfil atual sobre a reciclagem de
RCC no Rio de Janeiro. Algumas propostas para a melhoria do sistema gestor foram
apresentadas e sugerida a necessidade de um estudo mais aprofundado e de um levantamento
mais completo da realidade dos RCC no Município do Rio de Janeiro. / The RCC are originated of the diverse trials of the civil construction, with private enough

Previous issue date: 2006-08-09 / This is a descriptive study to verify if the strategic alliances generate sustainable competitive advantages in the sector of the civil construction, more specifically in the real estate companies and builders of residential property. To do this study, it was necessary to review the literature about the variable of the subject, and to develop the research in field by an application of quantitative approach utilizing a questionnaire for the information gathered on site. The sample was chosen by convenience consisting of 25 answers sheet sent by the executives of companies located within the metropolitan region of the city of São Paulo - SP, Brazil. The data collected were treated statistically by the model of the Exact Test of Fisher, for verifying the relationships between the variables of the problem: sustainable competitive advantages and strategic alliances. The objectives of this study, general, and specific, were achieved and was noted: that the companies researched indicated that they have made strategic alliances; that these strategic alliances were formally agreed with an apparent integration of activities between the partners; that the motivations and reasons of the companies researched, to have done the strategic alliances, are related by resources and complementary capacities; and that the sustainable competitive advantages achieved by the companies research should be related mainly with strategies for leadership of cost, for differentiation of products, and in the focus in market segments and product lines. The statistical analysis indicates a significant relationship between sustainable competitive advantages and strategic alliances. From an academic perspective, the study has its limitations of methodological and theoretical order and the results apply only to the company s components of the sample, and not with generalization or comparing to another company. / Este é um estudo descritivo para verificar se alianças estratégicas geram vantagens competitivas sustentáveis no setor da construção civil, mais especificamente das empresas incorporadoras e construtoras de imóveis residenciais. O estudo contou com o levantamento de referencial teórico sobre as variáveis do tema, e a pesquisa foi desenvolvida em campo pela aplicação de método quantitativo utilizando-se de um questionário para a coleta de dados. A amostra foi escolhida por conveniência constituindo-se de 25 respostas enviadas por executivos de empresas estabelecidas na região metropolitana da cidade de São Paulo SP. Os dados coletados foram tratados estatisticamente pelo modelo do Teste Exato de Fisher, para verificar os relacionamentos significativos entre as variáveis do problema: vantagens competitivas sustentáveis e alianças estratégicas. Os objetivos da pesquisa, geral, e específicos, foram alcançados constando-se: que as empresas pesquisadas indicam que têm feito alianças estratégicas; que estas alianças estratégicas têm sido formais e com aparente integração de atividades entre os parceiros; que os motivos das empresas pesquisadas para a constituição das alianças estratégicas parecem estar relacionados à obtenção de recursos e capacidades complementares; e que as vantagens competitivas sustentáveis decorrentes das alianças estratégicas feitas pelas empresas pesquisadas devem estar relacionadas principalmente com: estratégias para liderança de custo; para diferenciação de produtos; e no foco em segmentos de mercado e em linhas de produto. A análise estatística indica que pode haver relacionamento significativo entre vantagens competitivas sustentáveis e alianças estratégicas. O estudo apresenta limitações de ordem teórica e metodológica, ressaltando que seus resultados aplicam-se somente às empresas componentes da amostra, não podendo ser generalizados para nenhuma outra empresa.

Assessment of water footprint for civil construction projects / Analys av vattenavtryck i anläggningsprojektWärmark, Katarina January 2015 (has links)
Water is an irreplaceable resource and the strain on it is getting tougher. Around 40 per cent of the water withdrawn in Europe is for industrial use. With a growing population and an increased demand for food and energy per capita, the demand and pressure on our water resources will increase. CEEQUAL is a rating scheme for the civil construction industry and has raised the water footprint as an important sustainability issue to consider when choosing building materials. There is however little knowledge within the industry of how to do this. This paper offers information regarding available water footprint tools and gives a practical example using two of the most developed methods; the Water Footprint Network (WFN) method and Life Cycle Analysis (LCA). The case study showed that the results are very dependent on which method one chooses. The LCA method gives a bigger footprint since it is more inclusive than the WFN method. There are however some similarities when looking at which of the materials that are high-risk and low-risk materials when it comes to freshwater footprint. Among the studied products, steel was the material that uses and consumes the most water per kilogram, and could also be imported from water scarce areas. Fill material had a low water consumption and use per kilogram, but the huge amount used in the project makes it the material that used and consumed most water in total. Fill material is most often produced locally because of the large amount used, and was therefore not as significant when weighting the results by a water stress index. Calculating a water footprint can be used as a part of declaring the environmental performance of a project by including it in an Environmental Product Declaration (EPD), a sustainability report or by setting up an Environmental Profit and Loss (E P&L) account for water. It can also be used to identify and assess risks related to water use. / Färskvatten är en begränsad, men förnybar resurs som på grund av sina unika egenskaper saknar substitut i många processer och användningsområden. Resursen är ojämnt fördelad över världen och många lever idag i vattenstressade regioner. I Europa står industrisektorn för cirka 40 procent av det totala vattenuttaget. Med en växande befolkning och ökad efterfrågan på mat och energi per capita kommer konkurrensen om vattenresurserna att bli hårdare. Vi måste därför anpassa oss efter denna verklighet och framtid och börja använda våra färskvattenresurser mer effektivt. Certifieringssystemet CEEQUAL har lyft vattenavtryck för byggprodukter som en viktig fråga vid val av material. Inom branschen vet man i dagsläget inte hur man ska hantera den frågan och utgångspunkten för denna rapport är att ge vägledning bland de metoder som finns tillgängliga idag samt att ge ett praktiskt exempel på två av de mest utvecklade metoderna, Water Footprint Network (WFN) metoden och livscykelanalys (LCA). Som ett praktiskt exempel utfördes en fallstudie som visade att resultatet av en vattenavtrycksanalys beror väldigt mycket på vilken metod som väljs, vilket innebär att harmonisering inom branschen är viktigt. LCA-metoden ger ett större avtryck än WFNmetoden då metoden inkluderar fler typer av vattenanvändning. Av de studerade materialen visade sig stål vara det som både använder och förbrukar mest vatten per kilogram. Det är också ett material som i betydande grad importeras från regioner som kan vara vattenstressade. Fyllnadsmaterial var ett av materialen med lägst vattenavtryck per kilogram, men då det används i så stora mängder i anläggningsprojekt är det detta material som bidrar med störst totalt vattenavtryck. På grund av den stora mängd som används utvinns fyllnadsmaterial dock oftast lokalt. Detta gör att vattenavtryckets signifikans minskar när det viktas med ett vattenstressindex, då det generellt finns gott om vatten i Sverige. Vattenavtryck kan användas till deklaration av potentiell påverkan på vattenresurser genom att inkludera resultatet i en miljövarudeklaration eller hållbarhetsrapport. Det kan även användas i ett naturkapitalkonto (E P&L) för vatten eller för att identifiera risker kopplade till vattenanvändning samt ge vägledning vid materialval och val av leverantör.

Občanská stavba / Civil buildingBartošová, Andrea January 2020 (has links)
Basic of this Diploma thesis is Civil construction in Kostelec nad Orlici, which is in a part of city, where is planning off-grid community housing. Part of off-grid community housing is considered a partially sistainable civil construction, serving both for cultural use through the club, for commercial purposes such as various salons (hairdresser, massage or shop), as well as for sports activities with the possibility of small refreshments, such as bouldering, climbing wall and exercise hall. Four sustainable (off-grid) familly houses, which aren´t the subject of this thesis, are considered. Object SO01 – Civil construction is designed as a partially basement, two floors. The shape of the object is designed as several blocks with different height levels. From a material point of view it is a wooden building from the system of large-format laminated wood panels (CLT). The basement is designed with a waterproof reinforced concrete so-called white tub and prefabricated ceiling panels SPIROLL. A facade is made of wooden cladding, cement-fiber boards or thin-layer silicone plaster. A roof of the object is partially flat (vegetation and walkable) and a shed roof with a slope of 5°. A dance hall and the rest of the club + exit is located in the basement. A sanitary facilities, a technical room and a main entry with reception is also located in the basement. Right in the middle of the building is a climbing wall that runs across all floors. To the right of the climbing wall is a shop, exercise hall and staircase. To the left side are a sanitary facilities, a boulder (low climbing wall) and separate staircase for a office space on the 2nd floor. Behind the climbing wall is a bistro with entry for a terrace and entry for the club. There are some establishments like a hairdresser, a cosmetic salon, a tattoo salon and a massage salon on the 2nd floor. There are an entrance to a terrace above the bistro and a staircase to an attic and to second terrace as well on the 2nd floo
