Wind Loading On Trees Integrated With A Building Envelope, Aly Mousaad Aly, Alberto Zasso, Girma Bitsuamlak, Alberto Nicola Longarini, Arindam Gam Chowdhury
Faculty Publications
With the sustainability movement, vegetated building envelopes are gaining more popularity. This requires special wind effect investigations, both from sustainability and resiliency perspectives. The current paper focuses on wind load estimation on small- and full-scale trees used as part of green roofs and balconies. Small-scale wind load assessment was carried out using wind tunnel testing in a global-effect study to understand the interference effects from surrounding structures. Full-scale trees were investigated at a large open-jet facility in a local-effect study to investigate the wind-tree interaction. The effect of Reynolds number combined with shape change on the overall loads measured at …
Effects Of Reverberation And Noise On Speech Comprehension By Native And Non-Native English-Speaking Listeners, 2013 University of Nebraska-Lincoln
Effects Of Reverberation And Noise On Speech Comprehension By Native And Non-Native English-Speaking Listeners, Z. Ellen Peng, Lily M. Wang, Siu-Kit Lau, Adam M. Steinbach
Durham School of Architectural Engineering and Construction: Faculty Publications
Previous studies have demonstrated the negative impact of adverse signal-to-noise-ratios on non-native English-speaking listeners' performance on speech recognition using recall tasks, as well as implied that comprehension skills were more impaired than recognition skills under reverberation and noise. The authors have themselves previously conducted a pilot study on three native and three non-native Englishspeaking listeners to examine the effects of reverberation and noise using speech comprehension tasks. Those results suggested that speech comprehension performance is worse under longer reverberation times (RT), and that a longer RT is more detrimental to speech comprehension by non-native listeners than native listeners. This paper …
Acoustic Tweets And Blogs: Using Social Media In An Undergraduate Acoustics Course, 2013 University of Nebraska - Lincoln
Acoustic Tweets And Blogs: Using Social Media In An Undergraduate Acoustics Course, Lily M. Wang
Durham School of Architectural Engineering and Construction: Faculty Publications
Each fall, the author teaches an undergraduate architectural acoustics course to around 40 third-year architectural engineering students at the University of Nebraska. Beginning in 2011, a social media component was introduced to explore the use of this technology and how it may supplement the students' learning experience. Students were given an opportunity to receive extra credit by using Twitter and/or blogging about course material using a set hashtag (#AE3300) or through the course website. Results were positive, and the author will discuss pros and cons that she has experienced in adding this social media component. Suggestions for future implementations and …

Building Fabric Design : Thermal Performance Standards, 2012 Technological University Dublin
Building Fabric Design : Thermal Performance Standards, Joseph Little
Articles
This is the first of a series of articles using content from the new RIAI Building Fabric Design CPD which explores a range of themes of central importance to designing buildings that are highly energy efficient, genuinely compliant and perform to their design intent and specification. As the articles are short and the themes are often complex, they can be at best a short introduction to the issues raised. In this article we will look at the new minimum building fabric standards: these are far more onerous than much of the Industry understands.
Contractors' Competition Strategies In Bidding: Hong Kong Study, 2012 Hong Kong Polytechnic University
Contractors' Competition Strategies In Bidding: Hong Kong Study, Yongtao Tan, Liyin Shen, Craig Langston
Craig Langston
Selecting an appropriate competition strategy in bidding is the ambition of most contractors. The multiple requirements of clients encourage contractors to consider other strategies to deliver additional benefits besides offering a low-price bid. Offering low bids will reduce contractors' profits and potentially make development less attractive. Contractors need to understand their specific resources that generate competitive advantage and accordingly develop strategies to win contracts. This paper reports the findings from a recent survey on competition strategies in the Hong Kong construction industry. Thirteen typical bidding strategies, their used frequency in bidding, and their effectiveness for winning contracts of different types …
Construction Project Selection Using Fuzzy Topsis Approach, 2012 Hong Kong Polytechnic University
Construction Project Selection Using Fuzzy Topsis Approach, Young-Tao Tan, Li-Yin Shen, Craig Langston, Yan Liu
Craig Langston
Purpose - The purpose of this paper is to introduce a quantitative method for assisting contractors to select appropriate projects for bidding by considering multiple attributes and integrating decision group member opinions.
Design/methodology/approach - The fuzzy technique for order preference by similarity to ideal solution (TOPSIS) method is used to help contractors make decision on project selection and the linguistic terms are defined for representing the triangular fuzzy numbers for ratings of alternatives and weights of criteria.
Findings - The selection of appropriate projects for bidding is a multiple attribute group decision-making exercise. In a real decision process, there are …
Can We Teach Lean Construction Methods In Schools Of Architecture, 2012 Roger Williams University
Can We Teach Lean Construction Methods In Schools Of Architecture, Gary Graham
Fall 2012 Faculty Showcase
Traditionally, schools of architecture are not great laboratories to explore the collaborative processes and teamwork that are essential to integrated design and delivery practices as exemplified by Lean Construction. The pre-eminence of the “hero-architect” in the design studio is in direct conflict with methods that can reduce risk and improve the efficiency of the design and construction delivery process. Risk? Efficiency? Delivery Process?... not mention Cost Control, Schedule and Constructability, are foreign concepts to the predominant design studio culture.
Integrated practices and integrated project delivery are clearly “hot” topics in the design and construction industry today. They are a response …
Bond Between Self-Compacting Concrete And Reinforcement, 2012 Universidad de la Costa
Bond Between Self-Compacting Concrete And Reinforcement, Marian Sabau, Traian Onet, Ioan Pop
Marian Sabau
This paper study the bond behaviour of self-compacting concrete (SCC) in comparison to normal vibrated concrete (NVC). In this paper are presented the following parameters: the influence of bar diameter, the influence of concrete quality, the top-bar effect, the influence of active and passive confinement. In literature, different test results are found for the bond strength in SCC, which deliver contradictory results, but internationally it seems to be agreed that bond strength in SCC is slightly higher than NVC.
Hardened Properties Of Self-Compacting Concrete, 2012 Universidad de la Costa
Hardened Properties Of Self-Compacting Concrete, Marian Sabau, Traian Onet, Ana Ioana Petean
Marian Sabau
This paper presents the properties of hardened self-compacting concrete (SCC) and compare them to those reported for normally vibrated concrete (NVC). The mechanical properties evaluated are: compressive strength, modulus of elasticity, tensile strength, creep, shrinkage and bond with reinforcement. The very wide range of materials and mixes already used for SCC produced a significant scatter of data, but clear conclusions have been obtained. The compressive strength of SCC was likely to be the same or greater than that of NVC by using the same content of cement and water. Modulus of elasticity of SCC was lower than that of NVC …

Building Capability For Disaster Resilience, 2012 Bond University
Building Capability For Disaster Resilience, Lynn Crawford, Craig Langston, Bhishna Bajracharya
Lynn Crawford
All levels of government recognise the widespread devastation of communities by natural or other disasters. They have responded with emergency management arrangements and policies to enhance government and community capacity to anticipate, withstand and recover from disastrous events. Although the construction industry has a significant role to play, particularly in recovery and reconstruction, it has not generally been considered as a key stakeholder in building capability for disaster resilience. One barrier to more active involvement of the construction industry in disaster response and management is that traditional methods of construction project management have been criticised as too time consuming and …

Lifecycle Energy Consumption Prediction Of Residential Buildings By Incorporating Longitudinal Uncertainties, 2012 University of Nebraska-Lincoln
Lifecycle Energy Consumption Prediction Of Residential Buildings By Incorporating Longitudinal Uncertainties, Endong Wang, Zhigang Shen
Durham School of Architectural Engineering and Construction: Faculty Publications
Accurate prediction of buildings’ lifecycle energy consumption is a critical part in lifecycle assessment of residential buildings. Longitudinal variations in building conditions, weather conditions and building’s service life can cause significant deviation of the prediction from the real lifecycle energy consumption. The objective is to improve the accuracy of lifecycle energy consumption prediction by properly modelling the longitudinal variations in residential energy consumption model using Markov chain based stochastic approach. A stochastic Markov model considering longitudinal uncertainties in building condition, degree days, and service life is developed: 1) Building’s service life is estimated through Markov deterioration curve derived from actual …
Systemic Rework Risk Classification For Offshore Projects, 2012 Curtin University
Systemic Rework Risk Classification For Offshore Projects, Peter Love, Jim Smith, Sangwon Han
Jim Smith
Rework arises due to errors and omissions, and significantly contributes to project cost and schedule overruns in offshore projects. To acquire an understanding of the causal nature of rework in offshore projects, twenty three in-depth interviews with leading oil and gas industry practitioners were undertaken. The dialogue and narratives obtained from the interviews enabled the underlying dynamics of rework to be determined. A risk classification matrix is developed that can be utilized as a frame of reference to mitigate future rework. If rework risks are not given due consideration then there is the potential for latent conditions to become embedded …
Extending The Project Management Skillset To Encompass Change Implementation, 2012 Bond University
Extending The Project Management Skillset To Encompass Change Implementation, Lynn Crawford
Lynn Crawford
Project management standards address change control but are largely silent on change implementation. As the majority of projects involve some degree of organizational or behavioural change, and as project management is now applied to implementation of organisational changes as a specific project type, extension of coverage to recognise specific activities and competencies involved in effective change implementation should be considered in review of project management standards. As input to such a review, this paper presents results of research investigating the project and change implementation practices used, in practice, on projects requiring varying degrees of organizational and behavioural change.
Comparing Apples With Apples: Aligning Project Management Capability With Corporate Strategy, 2012 Bond University
Comparing Apples With Apples: Aligning Project Management Capability With Corporate Strategy, Lynn Crawford
Lynn Crawford
It makes little sense for an organization to invest in project management systems that are not directly suited to the nature of their business yet they need some form of guidance to tell them what good looks like. Generic project management maturity models can be a useful starting point but they take no account of differences in context and using them is like comparing apples with oranges. This paper presents results of research that investigates differences in strategic drivers and associated project management practices and outcomes between industries. Results of this research provide input to development of more compelling and …
A Vision For A Longer-Term Future: From Project Managers To “Synthesists”?, 2012 Bond University
A Vision For A Longer-Term Future: From Project Managers To “Synthesists”?, Alan Stretton, Lynn Crawford
Lynn Crawford
This paper first gives a snapshot of how some articulate contributors to a broader future-oriented non-management literature perceive the growth of specialization of avocations/ professions. A primary drawback is seen to be a resultant lack of people who are fluent in the language of many different disciplines, and who have the ability to expertly integrate them to achieve broader societal goals – i.e. “synthesists”.Project managers essentially integrate the contributions of many varied disciplines to achieve beneficial outcomes. Therefore project management appears to be extremely well placed to broaden its perspectives, and to develop and consolidate a role as “synthesists” in …
