“…When used appropriately, properly validated models can result in major benefits in various application fields (Yang et al 2011). Inaccurate models or those applied beyond their validity range, are insignificant WBGT-, and TWL-heat stress models against virgin data (collected from July to September 2010) to provide proof of the internal consistency and accuracy of each mathematical model (Chan et al 2012&2013ab).…”

Extremely hot and humid environments are common in numerous occupational settings. Construction work is tough and physically demanding, and the difficulty is exacerbated by the hot and humid weather of tropical and subtropical regions. Having established heat stress models through different environmental indicators, this study aims to ascertain which environmental indicator would be better able to predict the effects of heat stress on construction workers. Field studies were conducted during summer in Hong Kong from July 2011 to August 2011. Physiological, work-related, environmental, and personal parameters were measured to validate the established heat stress models on the basis of 411 sets of synchronized meteorological and physiological data collected from construction workers in two different construction sites. The mean absolute percentage error (MAPE) and Theil's U inequality coefficient were used to assess these models in terms of predictive accuracy. Wet bulb globe temperature (WBGT) was found to have the This is the Pre-Published Version.A c c e p t e d M a n u s c r i p t N o t C o p y e d i t e d2 highest validity (MAPE = 6.5%, Theil's U inequality coefficient = 0.05) and practicality in predicting the effects of heat stress on construction workers. Specific heat stress guidelines can be formulated based on WBGT, which can protect well the health and safety of site personnel working in hot and humid weather conditions.

“…To better relate validation with acceptance, it is helpful to consider the bridging concept of scientific credibility, defined by Schruben as “the willingness of persons to base decisions on information obtained from the model” [34] . One can consider validation as an important, or even essential, step in establishing scientific credibility [35] , [36] , but not necessarily sufficient in itself. Put another way, a lack of credibility can lead to the rejection of valid predictions [36] , [37] .…”

Highlights The role of validation in establishing the credibility of predictive methods is discussed. Various assessment frameworks for predictive methods have evolved independently, being developed by different communities. A set of seven credibility factors is proposed as a method-agnostic means of comparing the various assessment frameworks. It is hoped this will facilitate communication and cross-disciplinary collaboration between method developers and users.

“…The results of the industry experts were also used for validity purposes, and added more information about the implementation process. This technique of validity has already been used in different forms in construction [153][154][155]. For example, Lucko and Rojas [153] suggest that interviews with industry experts allow a richer feedback, as the researcher can clarify and extend individual factors ad hoc in a semi-structured manner [156].…”

Due to the complexity, high-risk, and conservative character of construction companies, advanced digital technologies do not become widely adopted in the short term, while vendors make determined efforts to overcome this and disseminate their technologies. This paper presents the methods of an investigation addressing the extremely complex issues related to the current practices of digital technology adoption in construction. It discusses how construction companies follow a specific logical process linked to need, project objectives, characteristics of the adopting organization, and the characteristics of the new technology to be adopted. The study aims to demonstrate a novel method of data collection and analysis including data and methodological triangulation techniques including the use of NVivo and AHP to explore how companies make the decision to uptake a new technology (e.g. advanced crane, tunnel boring machine or drones) by focusing on customer and vendor activities, their interactions, contributing factors, and people involved in the process. The major original contribution of this paper is to develop an innovative methodological Cube for investigating the Construction Technology Adoption Process (CTAP) covering technology adoption, acceptance, diffusion and implementation concepts. CTAP is a framework that delineates the phases of the process that customer organizations use when deciding to adopt a new digital technology and the parallel vendor activities. The significance of these contributions is that they enable vendors to understand how to match their strategies with customer expectations in each phase of the CTAP. It also provides a benchmark for new construction companies to use the current best practice of decision making. Future research is warranted to more clearly delineate any differences with developing nations or related industries such as mining and property management.
