“…NDE methods can be categorized into five main groups as shown in Figure 2: digital imaging, electro-magnetic (e.g., ground-penetrating radar), thermal (e.g., infrared thermography), electro-chemical (e.g., halfcell potential and electrical resistivity), and acoustic (e.g., chain dragging & hammer sounding, ultrasonic surface wave, ultrasonic pulse echo and impact echo). For more information about defects and NDE methods for highway bridge decks, the reader may refer to Abdelkhalek and Zayed [9], Yehia, et al [10], Omar and Nehdi [11], Abdelkhalek and Zayed [12], Gucunski, et al [13]. A brief description of these methods is presented through the following subsections.…”

Reinforced concrete bridge decks deteriorate over time primarily due to increasing traffic loads, severe environmental conditions, especially in North America, and deferred maintenance. Condition monitoring of those structures in a timely manner is of a great importance for making informed decisions regarding maintenance, rehabilitation and replacement strategies to preserve their value, maintain their levels of service and safeguard against catastrophic failures. The objective of this paper is to introduce a comprehensive review of the current state of the art on condition monitoring of reinforced concrete bridge decks. Deterioration progression of bridge decks including different types of defects (i.e., cracks, corrosion, delamination, spalling, honeycomb and voids), their associated causes and effects are introduced. Commonly used non-invasive and non-destructive evaluation methods, including digital imaging, ground-penetrating radar, infrared thermography, half-cell potential, electrical resistivity, chain drag & hammer sounding, ultrasonic surface wave, ultrasonic pulse echo and impact echo, are presented with their capabilities and limitations. A bibliometric analysis was conducted to investigate the current trend in condition monitoring. The review also examines the frequency of methods used in condition monitoring and provide a classification of recent studies according to study type (e.g., field or laboratory experiment), joint use (i.e., whether study applied method as a stand-alone or hybridized it with another method) and performance (i.e., whether study investigated performance indicators of the applied methods or not). The key stages in monitoring condition states of bridge decks considering risks are discussed. Current practices, challenges and future perspectives are also highlighted.

“…On-site crane layout planning Inclusion and exclusion criteria Clearly stating the exclusion and inclusion criteria in advance refrain the researchers from bias (Hussein and Zayed, 2020). In general, inclusion criteria provide the basis to include the articles that provide the necessary information for answering the research question (Abdelkhalek and Zayed, 2020;Tariq et al, 2021). While exclusion criteria include the basis on which non-relevant articles, duplicate articles and articles with no full-text available are omitted (Adegoriola et al, 2021).…”

Purpose This study aims to thoroughly examine the trends and developments of crane layout planning (CLP) in the construction field and reveal future research directions for modular integrated construction (MiC). Design/methodology/approach Through a rigorous systematic mixed-review methodology that integrates bibliometric, scientometric and qualitative analysis, this study explored the crane layout research trend; the scientometric analysis of journal sources and keywords occurrence network; the research contributions and links between influential countries; the classification of research articles based on the type of problems and solution approaches; the qualitative analysis of existing findings and research gaps; and the future research direction for CLP in MiC. Findings This study found five categories under the CLP domain, namely, crane selection, crane location, integrated crane selection and location, integrated crane location and allocation of supply points and hybrid problems. The major research approaches used to solve CLP is optimization (43%), visualization (23%), decision support systems (16%), simulation (11%) and qualitative techniques (7%). The possible future research directions include artificial intelligence-based models, multi-crane locations, CLP for MiC re-use, dynamic models representing real-life scenarios and building information modeling-based virtual reality models. Originality/value Through a mixed-review methodology, this study provides a comprehensive analysis of problem settings and solution methods of CLP while mitigating the subjectivity of traditional review methods. Also, it presents a repertoire on CLP and illuminates future directions for seasoned researchers in the context of MiC.

“…Impact Echo (IE) test is a point-wise evaluation method that is used to record a structure's response at different locations for multiple proposes [1]. For example, IE data can be used to indicate the thickness of a concrete slab [2] crack localization [3], detection of subsurface flaws such as delamination, honeycombing [4,5], deboning [6], and voids [7] in different experimental set ups. Raw IE data are signals where the horizontal axis represents surface acceleration of echo waves due to an impact at a point of structure and vertical axis represents time of wave travel in the structure.…”

Interpretation of IE data have been carried out by analyzing IE signals in frequency domain to determine the maximum frequency. However, the current peak frequency method can be inaccurate. The purpose of this research is to introduce features in IE signals that can be used for effective classification and interpretation for bridge deck evaluation through statistical analysis and Naive Bayes classifiers. The dataset contained IE data collected from eight slabs created at Advanced Sensing Technology FAST NDE laboratory (FHWA). A set of statistical features in time domain, normalized peak values, and length of preprocessed signals were used to classify the IE data, statistically. Then, Naive Bayes classifiers was employed to recognize defect area. Finally, the result of statistical classification was compared with frequency approach. The result shows that 19 and 21% of the IE signals collected from the defect area have multiple peaks, respectively. However, 85% of the IE signals collected from the sound set had only one peak. A probability classifier was used to find the relationship between the result of the frequency method and statistical analysis. The result shows that 10% of the IE signals were usable for estimating the thickness in the sound group.
