Prefabricated construction (PC) has attracted wide spread attention as a model of sustainable development for the construction industry of the future. Although the PC has many advantages, it is still ...at an initial stage in China. Based on the current conditions in China, this study focuses on the interrelationships of factors affecting PC promotion. Firstly, through a comprehensive review of relevant literatures and expert recommendations, 5 factors were identified: policy factor, technical factor, management factor, market factor and cost factor. Next, the data were collected through a questionnaire survey, and the questionnaire data were processed using SPSS 24.0 and AMOS 22.0. The overall relationships of each factor were quantitatively analyzed with Structural Equation Modeling (SEM). The results show that the policy factor plays a dominant role, while the management factor and market factors are also significant. This study also provides decision makers with relevant information about the factors involved, which will be helpful in devising appropriate strategies for the wider adoption of PC.
The construction industry has hit a plateau in terms of safety performance. Safety climate is regarded as a leading indicator of safety performance; however, relatively little safety climate research ...has been done in the Canadian construction industry. Safety climate may be geographically sensitive, thus it is necessary to examine how the construct of safety climate is defined and used to improve safety performance in different regions. On the other hand, more and more attention has been paid to job related stress in the construction industry. Previous research proposed that individual resilience may be associated with a better safety performance and may help employees manage stress. Unfortunately, few empirical research studies have examined this hypothesis. This paper aims to examine the role of safety climate and individual resilience in safety performance and job stress in the Canadian construction industry.
The research was based on 837 surveys collected in Ontario between June 2015 and June 2016. Structural equation modeling (SEM) techniques were used to explore the impact of individual resilience and safety climate on physical safety outcomes and on psychological stress among construction workers.
The results show that safety climate not only affected construction workers' safety performance but also indirectly affected their psychological stress. In addition, it was found that individual resilience had a direct negative impact on psychological stress but had no impact on physical safety outcomes.
These findings highlight the roles of both organizational and individual factors in individual safety performance and in psychological well-being.
Construction organizations need to not only monitor employees' safety performance, but also to assess their employees' psychological well-being. Promoting a positive safety climate together with developing training programs focusing on improving employees' psychological health — especially post-trauma psychological health — can improve the safety performance of an organization.
•80.6% of the respondents reported at least one occurrence of physical symptoms within the survey timeframe.•66.7% of the respondents reported at least one occurrence of safety events within the survey timeframe.•55.2% of the respondents reported at least one occurrence of psychological stress symptoms within the survey timeframe.•Safety climate affected construction workers’ physical safety outcomes as well as their psychological wellbeing.•Individual resilience was negatively associated with construction workers’ psychological stresses.
Os mecanismos dos sistemas de controle gerencial parecem facilitar mudanças estratégicas quando utilizados de forma interativa. Partindo deste pressuposto, o presente estudo teve como objetivo ...analisar a importância dos sistemas de controle gerencial na formação de estratégias utilizados nas empresas do ramo de construção civil, tendo como critério de análise o sistema de alavancas de controle destacado por Simons (1995). A pesquisa, caracterizada como descritiva, foi desenvolvida por meio de dois estudos de casos em empresas do setor de construção civil, localizadas na cidade de João Pessoa/PB. Para coleta dos dados foram utilizados os instrumentos: questionário adaptado por Moreira, Borges e Santiago (2017) que subsidiou a entrevista realizada com os gestores das empresas, como também foram coletadas informações em documentos e observação. Os resultados apontaram que as construtoras analisadas utilizam estratégias genéricas de foco e diferenciação voltadas para a comercialização de seus empreendimentos, sendo que uma possui planejamento de longo prazo e a outra se guia por perspectivas de curto prazo. Verificou-se, ainda, diferenças sistemáticas na utilização dos sistemas de controle gerencial e que as duas empresas possuem ferramentas de controle, contudo percebeu-se que existem com o objetivo de atender as normas estabelecidas por órgãos reguladores/certificadores, não sendo utilizadas para fins de tomada de decisão. Assim, concluiu-se que a influência dos sistemas de controles gerenciais na formação de estratégias dessas construtoras se dá de forma passiva, servindo os sistemas de controle gerencial como garantidores da realização das estratégias e metas organizacionais, mas não sendo os mesmos usados efetivamente como forma de identificação de oportunidades e fonte da formação de novas estratégias.

BIM (angl. Building Information Modelling) yra nagrinejamas visame pasaulyje, taciau BIM dimensijos dar iki šiol nera aiškiai apibrežtos ir išsamiai išnagrinetos. Šiuo metu pasaulyje yra ...priimtas bendras susitarimas tik iki penktos dimensijos, o nuo šeštos dimensijos bendro susitarimo nera. Tyrimo metu buvo analizuojamos BIM dimensijos literaturos šaltiniuose bei atlikta ju privalumu ir trukumu analize. Išanalizuoti privalumai ir trukumai buvo sugrupuoti pagal BIM dimensijas. Reikšminiai žodžiai: BIM, BIM dimensija, BIM dimensiju privalumai, BIM dimensiju trukumai. BIM (Building information modeling) is a process supported by various tools and is widely analyzed all across the world. Still BIM dimensions are not yet clearly classified and analyzed. At this moment, it is agreed to clasifie the main 5 dimensions of BIM. From the 6th onwards there is a wide debate on what each should be. This analysis covers BIM dimensions clarification in science literature adding strengths and weaknesses analysis that has been made for every dimension separately. Keywords: BIM, BIM dimensions, strengths of BIM dimentions, weaknesses of BIM dimentions.
ZusammenfassungSMPs haben eine eindrucksvolle Entwicklung seit den 1990er Jahren bis heute genommen. Im Markt für elastisches Kleben sind sie überproportional gewachsen und haben sich als fester ...Bestandteil etabliert. War dieser anfangs nur von einem Hersteller dominiert, haben sich über die Jahre immer mehr Firmen ein eigenes SMP‐Präpolymer‐ oder Produkt‐Portfolio aufgebaut. SMPs haben sich aus der Bauindustrie heraus in viele weitere Anwendungsfelder für elastische Fügemethoden weiterentwickelt. Sie zeichnen sich durch Vorteile wie Variabilität, einfache und sichere Handhabung, hohe Beständigkeit gegenüber Umwelteinflüssen und formbare Ästhetik aus. Das wichtigste Anwendungsfeld bleibt auch in naher Zukunft die Bau‐ und Heimwerkerindustrie. Zunehmend profitieren jedoch die Fahrzeug‐ und Maschinenbauindustrie von den Lösungen der elastischen Verklebungen und Dichtungen auf der Grundlage von SMPs.
Il termine "edilizia" rimanda a una conoscenza tecnico/costruttiva rapportata alla produzione, che include analisi sui rapporti tra gli elementi caratteristici della struttura del settore delle ...costruzioni (dimensione delle imprese, domanda e offerta di lavoro, costo della manodopera, costo di costruzione e costo della vita, ecc.) (Cicconi, 1981), che, se coniugata con il significato culturale di tecnologia, riporta attenzione su temi indagati nel passato dall'Area della Tecnología dell'architettura e che sarebbe di indubbio interesse riprendere per comprendere quanto e come la tecnica e l'innovazione possano trovare sbocco nella ricerca della qualita diffusa dell'abitare. Il saggio parte da una posizione che vede l'architettura come la risultante di un progetto basata sulla concezione sistemica, in cui le proprieta non possono essere ridotte a unita minori (Capra, 1982) ritenute insignificanti o ancillari. Ė una realta in cui saper distinguere "vincoli" materiali di stato di un luogo e in cui riconoscere condizioni e influenze con lo scopo di generare "possibilita" piü che affrontare "condizionamenti", azioni che richiedono un "pensiero progettante" sospeso tra le ragioni del fare e la tensione speculativa (Perriccioli and Nunziante, 2019). Leteronomia e una condizione ineludibile della concezione di sistema aperto, quale viene considerato il progetto di architettura, che governa il binomio teorie e prassi, praxis (l'agire) e techne (il fare) (Losasso, 2017) che incide sugli aspetti sociali, economici e ambientali della realta nell'attivo riconoscimento di esigenze collettive e individuali. Nel 1° ciclo (1950-64) si assiste a una generalizzazione della tecnologia del c. a. gettato in opera con schema puntiforme e solai alleggeriti con blocchi in laterizio, soluzione gia presente prima della guerra ma diventa poi prevalente, non tuttavia per un allineamento culturale ai dettami del Razionalismo o come innovazione strutturale tout court.
