Structural Design and Project Management: a Multi-Criteria Analysis to select the optimal seismic retrofit strategy for systems of complex buildings
No full textThe selection of the optimal strategy to seismically upgrade an existing building is a difficult problem. The difficulty increases in case of a complex buildings system with different strategic requirements in terms of organization layout and structural features. The questions concerns issues such as the complexity to combine management and technical strategies, especially in situations of comparable costs, and the selection of the optimal strategy in a range of possible solutions. It is demonstrated that the best way for influencing final cost obtaining stakeholders’ satisfaction is to intervene at the beginning of Design Stages.
In this contribution we present the implementation of a structured methodology of project management supported by Information Technology for the constructability performance evaluation of different seismic retrofit scenarios in order to choose the optimal retrofit solution in a complex buildings system. Evaluation criteria, using different constructability attributes, combined with evaluation systems are used to grade the different retrofit strategies.
The procedure intends to control building management during constructive phases since the early stage of the project. This is possible through the simulation of construction site in all the different prefigured scenarios. Managing the results in some specific tables, with a specific evaluation system it is possible to assess alternative management strategies. Similarly, taking information from a preset database, the procedure grades technical strategies. Finally combining structural and constructive strategies, the optimal retrofit solution is chosen.
Business Intelligence –mathematical models and decision making systems- applied to BIM technology for optimizing construction process during design phase is further future development in the industrial perspective
Computational workspaces management: a workflow to integrate workspaces dynamic planning with 4D BIM
No full textAn effective realization of a building construction project -without incurring in congested site areas or decline of productivity- tightly depends on the construction activities planning process that, should consider and manage site workspaces availabilities. In this context, in the past couple of decades many research efforts have been spent in BIM which represents the process of preparation and use of a computer-generated Building Information Model (BIM) even if effective integrated methodologies and models to assist construction workspaces management are still missing in the field. This contribution proposes an integrated model that aims to automate the creation of a building digital prototype, BIM-based, in which real site condition, in terms of workspaces allocation, are fully simulated. The outputs of a built-in algorithm to define the on-site workspaces configuration pattern based on the space syntax analysis together with a second one to automatically model workspaces geometries with minimizes input work are presented. Those algorithm are integrated in a coherent construction workspaces management workflow and tested on a simplified BIM of an industrial building, succeeding to allocate and model 611 workspaces required to construct 98 building items the BIM is composed of
Towards the BIM implementation for historical building restoration sites
No full textDealing with the renovation and restoration of historical building heritage often means facing several difficulties which not only concern ways of representing the ancient building and the design ideas, but also the phases of on-site interventions. The designers must always take into account a range of possible and compatible solutions that avoid endangering the cultural significance of the historical building. Traditional methods are often time-consuming and barely efficient, because they are related to the exchange of two-dimensional and paper-based support information.
Building Information Modelling (BIM) may represent an answer to these problems, allowing users to model the three-dimensional compounds of the building and to link a variety of information to it.
The aim of this article is to propose an innovative approach to the construction management of historical building interventions, based on BIM technologies, and explore different issues such as:
• parametric modelling of historical buildings, starting with laser scanner survey: LoD (level of detail) definition and measurement accuracy, with relation to modelling procedures;
• parametric modelling of the site and the several phases of restoration work in a fixed schedule (4D dimension);
• 3D graphic representation of safety procedures and related tools.
The subject of the case study is the SS. Nome di Maria church (Italy), built in 1748, which was seriously damaged during the earthquake that occurred in Italy in 2012

HBIM and Fire Prevention in Historical Building Heritage Management
No full textItaly possesses a unique cultural heritage that is constantly under threat from natural and anthropic risks: fire vulnerability is one of the main causes of architectural heritage destruction. The goal of this work is to propose a methodological approach to the management and preservation of historical building heritage with respect to fire safety. This approach aims to facilitate the process of analysis, design and fire management in historical buildings, using automated procedures based on HBIM (Historical BIM) processes. BIM can be used effectively in the digitization of cultural heritage: HBIM enables the three-dimensional modeling of the building by means of parametric objects, to which infographic information is associated, related to an appropriate Level of Development (LoD). A workflow process has been defined to set up a procedure for best practices which can guarantee the correct interoperability between BIM programs and fire safety design. The procedure, based on the exchange of IFC files, shows result applying analysis through Model Checking software of Model Checking and shows limited interoperability with fire safety software. The procedure has been validated through real tests and measurements, by comparing data obtained from a traditional fire prevention analysis with the data gathered from the automated procedure. The real case study is the ?Command Building? of the School of Air Warfare in Florence. Results mainly indicate that fire safety in historical buildings should always be managed using a performance-based approach (interoperability issue between HBIM and fire safety software)
A Decision Support System (DSS) for constructability assessment in seismic retrofit of complex buildings
Full text linkChoosing the optimal strategy for the seismic retrofit of an existing building is a difficult problem. This difficulty increases in the case of complex buildings systems with different strategic requirements in terms of organization layout and structural features. This paper contributes to solving this complexity by combining management and technical strategies, especially in situations of comparable times and costs. It is demonstrated that the best way to obtain final results that are consistent with the initial requirements is to intervene at the beginning of the design stage. To this end the implementation of a Decision Support System (DSS) aided by Information Technology (IT) is presented for making a constructability assessment of the seismic retrofit of complex buildings. Different seismic retrofit scenarios compete to be the optimal retrofit solution. Several evaluation systems are combined with classic constructability-based tools to produce an organic framework. A rule-based engine that utilizes this framework can be implemented on top of user-friendly software. The DSS intends to control building management by prefiguring a real ongoing building execution after the early stages of the project. This is made possible by using the simulation of site safety layout in all compatible scenarios. By managing the output data of IT models it is possible to assess both management and structural strategies. In the end the DSS combines them to choose the most favorable overall solution. Looking towards future development, it can be seen that applications of a BIM Platform integrated with the proposed DSS have considerable potential in construction management practice
Planning, management and administration of HS contents with BIM and VR in construction: an implementation protocol
No full textPurpose: Building construction is considered a complex, dynamic and highly hazardous process, which embraces many factors that are potentially dangerous to workers. Many studies proved that the improvement of preventive and proactive measures – dynamically included in the building design, planning and construction – could reduce site accidents as well as increase the site productivity. In this context, process management models and information visualization techniques such as building information modeling (BIM) and virtual reality (VR) seem to be devoted to strongly contribute to the advancement of the current safety management practices. For these reasons, the presented contribution is based on the assumption that a more nuanced approach for construction worker's safety training is warranted and the authors propose a safety training protocol based on BIM-enabled VR activity simulations. Design/methodology/approach: The methodology comprised a safety training protocol based on BIM-enabled VR activity simulations. The protocol addresses three methodological issues: (1) Planning in terms of training typologies and related health and safety contents to be implemented in the VR construction site scenarios; (2) Management regarding the solution to integrate BIM and game technologies to deliver VR training experiences; (3) Administration in terms of definition of standardized rules to define a safety training schedule in a given construction project. Findings: This work contributes to provide a standardized protocol for a viable integration of BIM and VR technologies for construction safety training in real projects. Practical implications: The VR training protocol was applied to a construction project based in Italy that served as case study for the development of the training sessions' contents and their implementation. This case demonstrated the feasibility of the protocol's implementation and pointed out the drawbacks and limitations on which further efforts need to be spent in order to take the proposed protocol from a prototypical stage to a maturity for its larger-scale adoption from the practitioners involved in construction safety training. Originality/value: The research gives a contribution to reduce the currently existing knowledge gap regarding how BIM and VR can be simultaneously integrated in real projects for construction safety training by using standardized rules to be extensively reproduced in different construction projects. It uses a customized toolkit with a mobile smartphone solution to administer Safety Training Scenarios which increases its portability in construction site compared to PC-based VR solutions
Constructability and safety performance based design: a design and assessment tool for the building process
No full textThe theme of this contribution fits astride two strands of Construction Management Studies: “health and safety risk management” on construction site and “constructability” design approach. Specifically we faces two problems usually considered separately: the lack of specificity, synergy, effectiveness between safety planning and construction process and the lack of concurrence between design and construction process. The proposed approach assigns to design the key role of optimizing both constructability and safety planning in a unique and simultaneous procedure. The purpose is to improve “working plan” design level by specific construction simulation and the related safety assessment in the perspective of the better constructability performance and final building results. The proposed method is a Construction Management Approach supported by design tool based on working directly on design drawings. Starting from the representation of construction details, their construction can be simulated. This is obtained analyzing construction details by means of progressive drawings that express and simulate the breakdown of construction phases, chronologically processed and logically related. In these specific drawings all the elements of the construction site are graphically placed. The procedure allows both to perform the specific and detailed safety assessment for the realization of construction detail components, and to verify the constructability of them. The safety and constructability analysis is so performed in a graphical way during the design process not waiting the construction phase. So we are still able to intervene, if necessary, with amendments under the designer control
