Title: Leveraging Digital Technologies for Civil Infrastructure: An Australian Perspective
Authors: J.A. Kraatz *, A.X. Sanchez and K.D. Hampson
Affiliation: Sustainable Built Environment National Research Centre, Curtin University, Bentley, Perth, Australia
Abstract: This paper will report on current research which is contributing to realising productivity benefits of digital modelling and integrated project delivery for the Australian transport infrastructure construction industry with a focus on the use of building information modelling (BIM) and virtual design and construction (VDC). Research is targeted on the delivery of road infrastructure projects and the potential to enhance productivity across the industry, with consequent significant positive impact on the Australian economy.
Specific objectives are to: (i) build an understanding of the current institutional environment and business systems and support which impact on the uptake of BIM/VDC in infrastructure; (ii) gather data to enable cross-country analysis of these environments; and (iii) provide strategic and practical outcomes for implementation in the delivery of BIM and VDC on transport infrastructure projects. This will be addressed in two parts: Part 1: The institutional environment of BIM and VDC uptake for road infrastructure; and Part 2: The role of knowledge intermediaries in education, training and the provision of business advice and support for BIM and VDC uptake for road infrastructure.Four activities will inform this research including a review of literature, desktop research, semi-formal interviews in Australia and Sweden, and a cross-country comparative analysis to determine factors affecting uptake and productivity improvements. These activities will seek to understand the state-of-practice versus best practices leading to IPD and BIM widespread adoption. This research will follow the BIM study framework developed by Succar (2009) that identifies three fields (technology, process and policy) interlocking with two sub-fields each: players and deliverables and establishes network-based integration as the last stage of BIM maturity.
Early findings will be discussed in this paper. Outcomes of this research will: inform a national public procurement strategy; provide guidelines for new contractual frameworks; and contribute to addressing skill gaps especially for SMEs in the context of Integrated Project Delivery (IPD) in Australia.

Abstract: Steel construction activities are often undertaken in an environment with limited climate control. Both hot and cold temperatures can physically and psychologically affect construction workers, thus decreasing their productivity. Temperature and humidity are two factors that constantly exert forces on workers and influence their performance and efficiency. Previous research studies have established the relationship between labor productivity and temperature and humidity. This paper is built on the existing body of knowledge, and develops a frame work of integrating building information modeling (BIM) with a lower level critical path method (CPM) schedule to simulate the overall impact of temperature and humidity on a healthcare facility's structural steel erection project in terms of total man hours and duration required to build the project. This research effort utilized historical weather data of four cities across the U.S., with each city having workable seasons all year around, to test if various project starting dates and locations of a project could significantly impact the project's schedule performance. It was found that both varied project start dates and locations significantly contribute to the difference in the work hours required to build the model project and that the project start date and location have an interaction effect. This research effort contributes to the overall body of knowledge by providing a framework that can help practitioners better understand the overall impact of a productivity influencing factor at a project level, in order to facilitate better decision making.

Title: Maximizing Value to Homeowners through BIM in Housing Refurbishment Projects
Authors: Kenneth Sungho Park and Ki Pyung Kim
Affiliation: School of Engineering and Applied Science, Aston University, Aston Triangle, Birmingham, B4 7ET, UK
Abstract: Construction clients are persistently seeking to maximize value and achieve sustainability. Sustainability becomes a major consideration in the construction industry as buildings are responsible for 45% of the total UK CO2 emission. In particular, the housing sector accounts for 28% of the total UK CO2 emission, and it is crucial to refurbish a whole house to achieve the sustainability agenda of 80% CO2 reduction by 2050. However, the whole house refurbishment deems to be challenging since the current construction practice is fragmented in nature and inefficient to integrate diverse information throughout the project lifecycle. As a response to the current challenges, Building Information Modelling (BIM) has been introduced as it is capable of managing construction projects in collaborative manner. Despite of the capability of BIM, the current uptake of the housing sector is lower as 25%. Thus, this research aims to investigate the value of homeowners to increase the uptake of BIM and exploring a possible solution to use BIM for whole house refurbishment projects. The questionnaire survey was conducted amongst 100 homeowners in the UK, and 39 UK construction professionals with an average of 18 years of experience in housing refurbishment were interviewed. The results of this investigation show that homeowners value initial cost more while construction professionals value thermal performance. It was also revealed that homeowners and construction professionals reached the same priorities in the roof as the first priority in refurbishment. Finally, this research has found that BIM requires a proper dataset and process map for whole house refurbishment.

Abstract: The conservative and fragmented Architecture-Engineering-Construction (AEC) industry is facing powerful change drivers and societal grand challenges. New information and communication technologies (ICT) have increasingly caught the attention of stakeholders as a mean to meet these challenges and to achieve goals of improving productivity, performance, sustainability and innovation. The current societal, economic and technological trends are requiring, driving and enabling change of practice, research and education - across traditional disciplines and curricula. This urges a systematic, interdisciplinary and holistic approach to problem solving and knowledge building, which again greatly challenges all actors involved. The aim of this paper is to explore the current status of implementing and using BIM and the related effects and expectations for change and improvement in construction projects and the Norwegian AEC-industry. Furthermore it will discuss future directions, both in a national and international context. The paper applies a holistic and multi-level approach to the explorations and discussions –from the 1) strategic and policy-making level by looking at the ambitions embedded in a governmental white paper “Good buildings for a better society” (2012), the resulting strategic collaborative authority-industry arena called Construction21 (Bygg21, 2013) and ongoing national joint research-initiatives, down to 2) project level by looking at and mapping the status and effects of implementing BIM, Virtual Design and Construction (VDC) and related collaborative models in R&D active AEC-organizations and ambitious pilot projects. The tool and measures for mapping the use and effects of using BIM in construction projects is developed by Kristensen, Andersen and Torp (2013). These tools and measures are currently piloted in several construction companies, and return an impression of the level BIM implementations and what is understood as its common use. The multi-level approach to the explorations was developed as a part of a research project (Moum, 2008) exploring relations between the building design process and the implementation and use of new ICT such as BIM. The research project demonstrated that the successful implementation and use of Building Information Modelling is affected by the many interdependencies, relations and interfaces embedded in the highly complex and partly unpredictable real world practice. The project concluded that a future challenge of research and practice is to better understand, master and balance these relationships - upstream and downstream across multiple levels, processes and activities. The paper will explore the current situation and trends in relation to the 2008-conclusions. The paper will show that there has been a shift in the AEC-industry from a technology-biased focus and “silo-thinking”, towards an increased awareness of the need for more integrated and holistic ways of thinking and collaborative working. It will furthermore give insight in current obstacles and the possibilities given by powerful initiatives on various levels, as well as the potential impact on the future development of the AEC-industry.
