Building Information Modelling (BIM) Continued digitization of the industry offers the opportunity to totally reinvent contemporary construction BIM non-adoption risks design and delivery practice for future development. Building Information Modelling (BIM) within the context Computer-aided design (CAD) of Architecture, Engineering & Construction (AEC) has been developing since the early 2000s and is considered to be a key technology. Despite major technical advancements in BIM, it has not been fully adopted and its definitive benefits have not been fully capitalized upon by industry stakeholders. The lack of widespread uptake of BIM appears to be linked to the risks and challenges that are potentially impeding its effectiveness. This paper aims to discuss the reality of BIM, its widespread benefits and current level of uptake. The risks and challenges associated with the adoption of BIM, as well as recommendations regarding how future BIM adoption could be developed are also highlighted.

BUILDING INFORMATION MODELING (BIM) IMPACT ON CONSTRUCTION PERFORMANCE by DAVID DYLAN JOHN (Under the Direction of Yunfeng (Cindy) Chen) ABSTRACT This study is designed to address the need for having a measure for Construction Performance on BIM-assisted construction projects. Through this study a new Construction Key Performance Indicator (CKPI) matrix is identified and created by the author. The CKPI could be used to assess BIM-assisted projects. Utilizing a sequential mixed methodology approach, academic and practitioner perspectives are assessed. A qualitative content analysis and quantitative descriptive analysis based on demographics are conducted to establish a better understanding of BIM and Construction Performance. The academic perspective is used to assess the relevance of BIMM and CKPI indicators, and the practitioner perspective is used to assess the extent to which BIM addresses the indicators.

  • Understanding Ventilation in Hot Humid Climates 2006-10-26 by Joseph Lstiburek
    building science.com © 2006 Building Science Press All rights of reproduction in any form reserved. Building Science Digest 107 Understanding Ventilation in Hot Humid Climates 2006-10-26 by Joseph Lstiburek Abstract: Adding outdoor air in hot humid climates causes moisture problems right? Sometimes. It depends on the condition of the house before you start to add outdoor air. Contrary to popular belief, most houses in hot, humid climates are over ventilated due to duct leakage and induced air change from internal air pressure effects due to unbalanced air flow and door closure. In most houses when HVAC systems are operating, air change rates of between 0.5 and 1.0 ach are common. Between 150 cfm and 200 cfm of outdoor air is typically introduced in this manner when systems are operating. When HVAC systems are not operating, air change rates of between 0.1 ach and 0.2 ach are common due to stack forces and wind. ASHRAE Standard 62.2 recommends adding approximately 40 to 50 cfm of outdoor air. If duct leakage and pressure effects are addressed, no additional latent load is added during full load periods. The uncontrolled air change is dropped to near zero and controlled air change is added in its place. The resultant latent load is typically similar or lower than standard practice – again under full load. However, if outdoor air is added to a standard house with duct leakage and internal pressure effects, moisture problems are almost assured - duct leakage and internal air pressure effects must be addressed. Even if duct leakage and internal pressure effects are addressed, the latent loads introduced by ventilation air during part load periods are significant and must be addressed.

Abstract While BIM processes are established for new buildings, the majority of existing buildings is not maintained, refurbished or deconstructed with BIM yet. Promising benefits of efficient resource management motivate research to overcome uncertainties of building condition and deficient documentation prevalent in existing buildings. Due to rapid developments in BIM research, involved stakeholders demand a state-of-the-art overview of BIM implementation and research in existing buildings. This paper presents a review of over recent 180 publications on the topic. Results show scare BIM implementation in existing buildings yet, due to challenges of (1) high modeling/conversion effort from captured building data into semantic BIM objects, (2) updating of information in BIM and (3) handling of uncertain data, objects and relations in BIM occurring in existing buildings.
