Review Of Performance Measurement: Implications For Public–Private Partnerships, Junxiao Liu, Peter Love, Jim Smith, Michael Regan, Ekambaram Palaneeswaran Aug 2015

Review Of Performance Measurement: Implications For Public–Private Partnerships, Junxiao Liu, Peter Love, Jim Smith, Michael Regan, Ekambaram Palaneeswaran

Michael Regan

Purpose – The purpose of this paper is to review the normative literature in regard to public-private partnerships (PPPs) and their evaluations, and attempts to investigate whether the Performance Prism is a feasible framework for effective PPP performance measurement. Design/methodology/approach – An in-depth and critical literature review is conducted in this study. Discussion concentrates on PPP features, performance measurement in PPPs, performance measurement in construction, and characteristics of the Performance Prism. Findings – The Performance Prism exhibits a strong ability to capture the distinct features of PPP infrastructure projects and can be considered as a framework suitable for effective and …


Book Review, Earthea Nance Dec 2014

Book Review, Earthea Nance

Earthea Nance, PhD (Stanford University, 2004)

Book Review published in the journal Water International (2015) The topic… “The book builds upon Nance’s research and presents a comprehensive account of Brazil’s experience of implementing condominial sewerage.” The topic… “From the very beginning, the author expresses her concerns in escaping from preconceived ideas about conventional and participatory development, positioning her views within a third wave of post-structural development discourse, neither universalist nor relativist, that is neither denying nor overvaluing the social content of development.” Research methods… “Nance manages to do so by integrating different areas of established knowledge and examining her research issue from a privileged historical perspective. …


Use Of Multidepth Deflectometers And Strain Gauges To Investigate The Differential Movement At Railway Bridge Approaches, D. Mishra, E. Tutumluer, H. Kazmee, H. Boler Apr 2014

Use Of Multidepth Deflectometers And Strain Gauges To Investigate The Differential Movement At Railway Bridge Approaches, D. Mishra, E. Tutumluer, H. Kazmee, H. Boler

Debakanta Mishra

This paper presents findings from on ongoing research study at the University of Illinois focusing on the instrumentation and performance monitoring of railroad bridge approaches using multidepth deflectometers and strain gauges. Different sensors installed at the selected approaches are introduced, and details of the instrumentation activity are explained. Example track settlement data acquired over time is presented to compare the contributions of different substructure layers to the permanent deformation accumulation. Similarly, transient track deformation data gathered for train loading is presented to highlight the contributions of individual track substructure layers towards the total transient deformations. The ballast layers appear to …

Analysis Of Segmentation Algorithms For Pavement Distress Images, Allen Downey, Haris N. Koutsopoulos, Ibrahim El Sanhouri Jun 2012

Analysis Of Segmentation Algorithms For Pavement Distress Images, Allen Downey, Haris N. Koutsopoulos, Ibrahim El Sanhouri

Allen B. Downey

Collection and analysis of pavement distress data is an important component of any pavement‐management system. Various systems are currently under development that automate this process. They consist of appropriate hardware for the acquisition of pavement distress images and, in some cases, software for the analysis of the collected data. An important step in the automatic interpretation of images is segmentation, the process of extracting the objects of interest (distresses) from the background. We examine algorithms for segmenting pavement images and evaluate their effectiveness in separating the distresses from the background. The methods examined include the Otsu method, Kittler's method, a …


Primitive-Based Classification Of Pavement Cracking Images, Allen Downey Jun 2012

Primitive-Based Classification Of Pavement Cracking Images, Allen Downey

Allen B. Downey

Collection and analysis of pavement distress data are receiving attention for their potential to improve the quality of information on pavement condition. We present an approach for the automated classificaton of asphalt pavement distresses recorded on video or photographic film. Based on a model that describes the statistical properties of pavement images, we develop algorithms for image enhancement, segmentation, and distress classification. Image enhancement is based on subtraction of an “average” background: segmentation assigns one of four possible values to pixels based on their likelihood of belonging to the object. The classification approach proceeds in two steps: in the first …


Design And Construction: Building In Value, Rick Best, Gerard De Valence Dec 2001

Design And Construction: Building In Value, Rick Best, Gerard De Valence

Rick Best

The design and construction of buildings is a lengthy and expensive process, and those who commission buildings are continually looking for ways to improve the efficiency of the process. In this book, the second in the Building in Value series, a broad range of topics related to the processes of design and construction are explored by an international group of experts. The overall aim of the book is to look at ways that clients can improve the value for money outcomes of their decisions to construct buildings.

The book is aimed at students studying in many areas related to the …
