O presente trabalho inserido na Unidade Curricular de DIPRE, do Mestrado em Engenharia Civil do Instituto Superior de Engenharia do Porto, foi desenvolvido na Universidade do Luxemburgo. O trabalho insere-se num projeto mais extenso denominado SiMCo, acrónimo para “Steel in Modern Construction”, e é liderado pela empresa de aço multinacional ArcelorMittal. O projeto SiMCo tem como objetivo promover o aço de alto valor acrescentado (AVA) da marca ArcelorMittal e criar uma metodologia que permite a comparação de edifícios funcionalmente equivalentes, projetados em aço AVA e os construídos com materiais de construção mais convencionais e competitivos, como por exemplo betão pré-fabricado.
Neste trabalho foram estudadas 6 variantes construtivas diferentes de um mesmo edifício de escritórios tipo, nomeadamente no que diz respeito ao planeamento da construção e a organização do estaleiro, tendo como objetivo a otimização tanto do planeamento como da logística no estaleiro. Adicionalmente, a definição de detalhes construtivos, bem como a análise das etapas de produção necessárias à execução foram realizadas.
No planeamento da construção das várias variantes foi utilizada uma metodologia inovador, desenvolvida maioritariamente aplicada no seio de grandes empresas de construção francesas. Nesta metodologia, a abordagem aplicada para o cálculo da duração da construção baseia-se na carga horária da grua ou das gruas presentes no estaleiro, com o objetivo de otimizar ao máximo a eficácia das gruas, de modo a obter uma organização de estaleiro rentável em que as gruas estejam sempre em movimento e a trabalhar com um alto desempenho durante toda execução das estruturas. A aplicação destas abordagens necessitou o uso e a atualização do um programa VBA denominado “ChaCAD”, no qual os diferentes tempos de grua estão incorporados numa base de dados, permitido a análise do planeamento da estrutura baseado nas quantidades extraídas de um modelo 3D.
De seguida, as cadências e sequências de construção, os recursos humanos e matérias foram calculados e a logística de estaleiro foi desenvolvida. Um plano de estaleiro foi igualmente elaborado.
Por fim, o processo de construção das várias opções construtivas foi simulado em BIM 4D com o software Navisworks, o que não só permitiu visualizar eficazmente a execução das diversas variantes, como também apoiou a otimização do planeamento e possibilitou a comparação visual de todas as variantes estudadas.
This paper is integrated in the DIPRE curricular unit of the Master in Civil Engineering of the Instituto uperior de Engenharia do Porto, and was developed at the University of Luxembourg. It’s embodied in an important research project called SiMCo, acronym for “Steel in Modern Construction”, which is led by multinational steel manufacturing cooperation ArcelorMittal. The goal of the project SiMCo is to promote high added value (HAV) steel of ArcelorMittal’s brand and to create a methodology that allows the comparison between functionally equivalent buildings, built with HAV products and those constructed with competitive products and materials, such as precast concrete. In this work, six different constructive options were analysed on the basis of one study case office building, particularly with regard to construction planning and construction site organisation, having for a purpose the optimisation of the planning, as well as construction site’s logistic and installations. Additionally, constructive details and necessary work steps in the production process were analysed and defined.An innovating methodology was used for the construction planning of each studied variant, which was development an d is widely applied by big French construction companies. In this methodology, the pproaches used for calculations of the construction duration are based on the workload of the crane or cranes on the construction site, with the purpose to optimise to a maximum the effectiveness of those cranes. This means, for a profitable construction site organisation the cranes should always be in movement and working with a high effectivity. Therefore, the on Excel based VBA program “ChaCAD” was sed and extended, in which different crane times are embedded for the analysis of structural work based on operational measurement issued from 3D model. Based on the approaches stated above, work cadences, work flow, material and human resources were alculated and construction site logistics were developed. Furthermore, a construction installation plan for the most interesting variant was elaborated. Finally, the construction progress of the various cases analysed was simulated in BIM 4D with the software avisworks, which not only allows a better visualisation of the construction progress of each variant, but furthermore helped to optimise the work schedule, and validate and oppose the different structural options. At last, it also allows a better monitoring on building site for the later construction.
