Modelo para planejamento e controle logístico de obras de sistemas pré-fabricados do tipo engineer-to-order com o uso de BIM 4D

Bortolini, Rafaela January 2015 (has links)
O planejamento e controle logístico cumpre um importante papel no processo de montagem de sistemas construtivos pré-fabricados, e pode ter um impacto substancial nas metas do empreendimento em termos de prazo, custo, qualidade e segurança. A falta de planejamento logístico na construção pode causar congestionamento em postos de trabalho e resultar em baixa produtividade. Building Information Modeling (BIM) tem sido apontado como uma grande oportunidade para a melhoria do desempenho da logística de canteiros, principalmente pelo uso de modelos 4D para analisar planos de construção, assim como reduzir conflitos espaciais em canteiros de obras. Entretanto, modelos 4D têm sido frequentemente utilizados simplesmente para representar a sequencia de execução definida em uma rede CPM, sem considerar atividades que não agregam valor, tais como estoques e transporte. Visando a preencher esta lacuna, esta pesquisa propõe um modelo para o planejamento e controle logístico para sistemas construtivos pré-fabricados do tipo engineer-to-order, utilizando BIM 4D. Pesquisa construtiva foi a abordagem metodológica adotada nesta pesquisa. Quatro estudos empíricos foram realizados em diferentes canteiros de obras de uma empresa de estrutura metálica, nos quais processos logísticos foram planejados e controlados. O estudo também propôs diretrizes para integrar o planejamento logístico ao planejamento e controle da produção e para o uso de gestão visual para apoiar o controle logístico. O modelo proposto sugere que o desenvolvimento e uso de modelos 4D para controle e planejamento logístico deve ter uma ampla participação de diferentes intervenientes. / Logistics planning and control plays a key role in the process of assembling prefabricated building systems, and can have a major impact in project goals in terms of schedule, cost, quality and safety. The lack of construction logistics planning may cause congestion in workspaces and result in low productivity. Building Information Modeling (BIM) has been pointed out as a major opportunity for the improving the performance of site logistics, especially by using 4D models to analyze construction plans as well as to reduce spatial conflicts in construction sites. However, 4D models have been often used simply for representing the installation sequence defined in a CPM network, without considering non value-adding activities, such as inventories and transportation. In order to fill this gap, this research work proposes a logistics planning and control model for engineer-to-order prefabricated building systems using BIM 4D. Constructive research was the methodological approach adopted in this investigation. Four empirical studies were carried in different construction sites of a steel fabricator company, in which logistic processes were planned and controlled. This study also proposes guidelines for integrating logistics planning and control with production planning and control, and for the use of visual management to support logistics control. The proposed model suggests that the development and use of 4D models for logistics planning and control should have a broad participation of different stakeholders.

Livscykelanalys av volymelement i produktskedet / Life cycle assessment for the product stage for a prefabricated module unit

Andersson, Christoffer, Nilsson, Tilda January 2020 (has links)
Den globala uppvärmningen har lett till att Sveriges regering, för att uppfylla de globala klimatmålen, har tagit fram ett lagkrav som är tänkt att träda i kraft från 1 januari 2022. Lagkravet innebär att utsläpp av växthusgas ska dokumenteras för byggnader över hela deras livscykel. Syftet och målet med examensarbetet är att undersöka och analysera en modulbyggnads klimatpåverkan under produktskedet. Objektet som undersöks är en byggnadsmodul med bostadsytan 40,6 m2, som ingår i ett större flerbostadshus. Klimatpåverkan har beräknats och analyserats i form av en livscykelanalys med Byggsektorns Miljöberäkningsverktyg. Analysen är avgränsad till modulens produktskede inklusive råvaruförsörjning, transport och tillverkning av modulen. Resultatet av studien är att modulen släpper ut 124,8 kilogram koldioxidekvivalenter per kvadratmeter enligt specifika data. Mest utsläpp av växthusgaserx kommer från materialet korslimmat trä och från energikällorna som används vid tillverkningen av byggprodukter och modulen. / Global warming has led to the Swedish government, as part of the global climate goals, to propose a legislative requirement that is supposed to come into force from January 1, 2022. The forthcoming legislative requirement will stipulate that greenhouse gas emission from buildings' life cycle are documented and presented. The purpose and goal of this thesis is to investigate and analyze the climate impact of a prefabricated building module during the product stage. The object investigated is a building module with a living area of 40.6 m2, which is part of a larger apartment building. The climate impact has been calculated and analyzed with life cycle analysis approach using the Construction Sector's Environmental Calculation Tool (Byggsektorns miljöberäkningsverktyg). The analysis is limited to the product stage of the module including extraction and processing of raw materials, transportation and manufacturing of the module. The result of the study is that the modules climate impact is 124.8 kilograms carbon dioxide equivalents per square meter according to specific data. The major part of greenhouse gas emissions comes from the material cross laminated wood and from energy sources being used in the manufacturing of building products and the module.

Mikho, Mikael, Sandegren, Simon January 2020 (has links)
Vid byggnation av betongväggar på vatten- och reningsverk används dom tvåmetoderna platsgjutna och prefabricerade väggar. Metoderna ger liknande resultatmen skiljer sig avsevärt i genomförande. Vi har därför valt att studera ämnet och draslutsatser om vilken metod som är att föredra.För att studera ämnet valde vi Skebäcks Reningsverk i Örebro som studieobjekt därdom båda metoderna att uppföra nya mellanväggar i betong har använts i sambandmed ombyggnation av befintliga bassänger.Vi har valt att studera kostnader och arbetsmiljöfrågor kring dom två olikabyggmetoderna.Som underlag för kostnadsberäkningen har vi använt Wikells Sektionsdata samtprisuppgifter från leverantörer. För att studera arbetsmiljön har intervjuer genomförtsmed två yrkesverksamma betongarbetare. Intervjuerna gav sedan underlag för enenkät som skickades ut till yrkesverksamma betongarbetare.Vår studie visar att prefabricerade väggar beräknas ge en lägre byggkostnad änmotsvarande platsgjuten vägg vid ett reningsverk. Studien visar även attbetongarbetare föredrar prefabricerade lösningar ur arbetsmiljösynpunkt. Fysisktpåfrestande moment undviks och tiden som spenderas på arbetsplatsen minskar vidprefabricerade betongelement. / When building concrete walls at water and wastewater treatment plants , the twomethods are cast-in-place and prefabricated walls. The methods give similar resultsbut differ considerably in implementation. We have therefore chosen to study thesubject and draw conclusions about which method is preferable.To study the subject, we chose Skebäcks wastewater treatment plant in Örebro as astudy object where both methods of constructing newpartitions in concrete havebeen used in connection with the reconstruction of existing basins.We have chosen to study costs and work environment issues around the twodifferent construction methods. As a basis for the cost calculation, we have usedWikell's Sektion Data and price information from suppliers. To study the workenvironment, interviews were conducted with two professional concrete workers. Theinterviews then provided the basis for a questionnaire that was given to professionalconcrete workers.Our study shows that prefabricated walls provide a lower construction cost than thecorresponding cast-in-place wall at wastewater treatment plant . The study showsthat concrete workers prefer prefabricated solutions from a work environment pointof view. Physically stressful moments are avoided and the time spent in theworkplace is reduced when building with prefabricated concrete walls.
