Building information modelling (BIM) implementation and remote construction projects: issues, challenges, and critiques.
The construction industry has been facing a paradigm shift to (i) increase productivity, efficiency, infrastructure value; quality and sustainability (ii) reduce lifecycle costs, lead times and duplications via effective collaboration and communication of stakeholders in construction projects. This paradigm shift is becoming more critical with remote construction projects, which reveals unique and even more complicated challenging problems in relation to communication and management due to the remoteness of the construction sites. On the other hand, Building Informational Modelling (BIM) is offered by some as the panacea to addressing the interdisciplinary inefficiencies in construction projects. Although in many cases the adoption of BIM has numerous potential benefits, it also raises interesting challenges with regards to how BIM integrates the business processes of individual practices. This paper aims to show how BIM adoption for an architectural company helps to mitigate the management and communication problems in remote construction project. The paper adopts a case study methodology, which is a UK Knowledge Transfer Partnership (KTP) project of BIM adoption between the University of Salford, UK and John McCall Architects (JMA), in which the BIM use between the architectural company and the main contractor for a remote construction project is elaborated and justified. Research showed that the key management and communication problems such as poor quality of construction works, unavailability of materials, and ineffective planning and scheduling can largely be mitigated by adopting BIM at the design stage
Fast Power and Energy Efficiency Analysis of FPGA-based Wireless Base-band Processing
Nowadays, demands for high performance keep on increasing in the wireless
communication domain. This leads to a consistent rise of the complexity and
designing such systems has become a challenging task. In this context, energy
efficiency is considered as a key topic, especially for embedded systems in
which design space is often very constrained. In this paper, a fast and
accurate power estimation approach for FPGA-based hardware systems is applied
to a typical wireless communication system. It aims at providing power
estimates of complete systems prior to their implementations. This is made
possible by using a dedicated library of high-level models that are
representative of hardware IPs. Based on high-level simulations, design space
exploration is made a lot faster and easier. The definition of a scenario and
the monitoring of IP's time-activities facilitate the comparison of several
domain-specific systems. The proposed approach and its benefits are
demonstrated through a typical use case in the wireless communication domain.Comment: Presented at HIP3ES, 201
