Building information model implementation for existing buildings for facilities management: a framework and two case studies

This paper presents the process of implementation of a building information model for managing an existing building, identifying a development framework and documenting the difficulties that occurred during the implementation of the initial stages. The use of building information modelling (BIM) for the design and construction phase of a building has been thoroughly looked into by researchers and practitioners and there is evidence to support that it is beneficial for reducing cost, time and improving communication. A single shared building information model results in a greater accuracy, clarity and consistency of the information available during the life cycle compared to traditional 2D/3D drawings. Yet the potential use of BIM for the operational and management phase (facilities management), besides maintenance schedules and equipment information and location, is still not clearly identified. The UK Government, institutional clients and major private owners are now demanding BIM for new construction and major refurbishment, but given that 70–75% of the UK building stock that will exist and be in use in 2050 has already been built, a significant part of the existing facilities will not have a building information model till the next major refurbishment. This creates a major gap in the built environment, when it comes to having BIM for existing buildings. This paper presents the initial findings of two case studies, where building information models were developed for two existing buildings using a new framework and concludes that minimal BIM skills are sufficient to construct a base building model that can be implemented over time by facilities managers

Dynamic modelling of a 3-CPU parallel robot via screw theory

The article describes the dynamic modelling of I.Ca.Ro., a novel Cartesian parallel robot recently designed and prototyped by the robotics research group of the Polytechnic University of Marche. By means of screw theory and virtual work principle, a computationally efficient model has been built, with the final aim of realising advanced model based controllers. Then a dynamic analysis has been performed in order to point out possible model simplifications that could lead to a more efficient run time implementation

Tools and Methods for Human Robot Collaboration: Case Studies at i-LABS

The collaboration among humans and machines is one of the most relevant topics in the Industry 4.0 paradigm. Collaborative robotics owes part of the enormous impact it has had in small and medium size enterprises to its innate vocation for close cooperation between human operators and robots. The i-Labs laboratory, which is introduced in this paper, developed some case studies in this sense involving different technologies at different abstraction levels to analyse the feasibility of human-robot interaction in common, yet challenging, application scenarios. The ergonomics of the processes, safety of operators, as well as effectiveness of the cooperation are some of the aspects under investigation with the main objective of drawing to these issues the attention from industries who could benefit from them
