Yet the adoption of these methods can be extremely difficult to accomplish and requires significant change management efforts. To facilitate the APDM adoption, this research aimed to better understand how AEC owner organizations have changed from only using the design-bid-build method to also successfully implementing APDMs from an organizational change perspective. This research utilized a literature review, survey and interviews to fulfill the research objectives. The dissertation follows a three paper format. The first paper focuses on identifying organizational change management (OCM) practices that, when effectively executed, lead to increased success rates of adopting APDMs in owner AEC organizations. The results of the first paper indicated that the five OCM practices with the strongest correlations to successful APDM adoption were realistic timeframe, effective change agents, workload adjustments, senior-leadership commitment, and sufficient change-related training. The second paper focuses on investigating AEC employees’ reactions to the adoption of APDMs. The findings of the second paper revealed that employees in AEC organizations react favorably to adopting a change in their project delivery systems. The findings further revealed that increasing the use of OCM practices is related to decreased employee resistance to change. The third paper aimed to provide guidelines detailing on how to lead APDM adoption. The findings of the third paper indicated that there was a general sequence of four implementation phases, which were preparing and planning, pilot project testing, expanding to the intended scale, and sustaining and evaluating. The phases include specific OCM practices that increase the probability of successful APDM adoption. The dissertation results can help in guiding the senior managers of construction organizations and OCM consultants to effectively implement APDMs for the first time in the construction sector.Dissertation/ThesisDoctoral Dissertation Construction Management 202

The fibers content appropriate for the concrete matrices investigated was also determined based on flexural tests on standard prisms. Parameters investigated include: matrix compressive strength ranging from 45 MPa to 70 MPa, corresponding to normal and high strength concrete matrices respectively; fibers volume fraction including 0, 0.5%, 0.76% and 1%, equivalent to 0, 40, 60, and 80 kg/m<sup>3</sup> of hooked-end steel fibers respectively. Test results indicated that flexural strength and toughness of normal and high strength concrete matrices were significantly improved with the increase in the fibers content added; whereas a slight improvement in compressive strength was observed for the same matrices. Furthermore, the test results indicated that the effect of increasing the fibers content was more pronounced...
Employee Reactions to Adoption of Alternative Project Delivery Methods within the AEC Industry

Yet implementation of these methods requires an organizational change effort. One of the challenges facing organizations that are implementing organizational change initiatives is employee resistance to change. The aim of this study was to investigate AEC employees’ reactions to the adoption of APDMs and to examine the methods used to communicate the APDM adoption to employees. To achieve the aim, survey responses were collected from 140 respondents across AEC owner organizations in the United States. Results indicate that employees in AEC owner organizations react favorably to adopting a change in their project delivery systems. Results further reveal that increasing the use of organizational change management (OCM) practices is related to decreased employee resistance to change. Surprisingly, employee reactions do not mediate the relationship between OCM practices and APDM adoption. The findings also indicate that the most effective ways to disseminate change messages to employees are presentations, on-the-job support, and meetings. The findings of this study may be useful for change practitioners in which employees’ reactions toward the changes in project delivery methods are more supportive than resistive to change.

High-strength steel-fibre-reinforced concrete: potential use for ground slabs applications
Proceedings of the Institution of Civil Engineers - Transport, 2017

Three full-scale (3 m × 3 m × 0·1 m) slabs were precast, placed on a rubber mat, resting on a concrete floor, and centrally loaded either to failure or to the maximum loading-jack capacity. The tested load-carrying capacity of each slab was compared to theoretically estimated values using the Meyerhof model. Test results indicated that the addition of 60 kg/m3 (0·76% by volume) of hooked-end steel fibres to concrete significantly increases the load-carrying and displacement capacities, changes the mode of failure from brittle to ductile, reduces cracking on bottom and top surfaces of the slab and allows a significant reduction in slab thickness. Increasing the concrete matrix strength of steel-fibre-reinforced concrete slab from 45 to 85 MPa had a marginal effect on the load-carrying capacity of the slab at points on the displacement response beyond the...

Therefore, understanding the various factors that influence the bid/no-bid decision is crucial for construction companies in determining whether to pursue a project. The present study aims to identify the critical factors influencing contractors’ bid/no-bid decisions. A total of 112 responses were collected from a questionnaire survey to rate the relative importance of 22 factors, and these factors were then analyzed based on the type of project and the contractor’s years of experience. The results indicate that the client’s ability to pay, clarity of the scope of work, project cash flow, the need for work, and availability of qualified labor are the most critical factors influencing contractors when making bid/no-bid decisions. The factor “previous experience in similar projects” was statistically significant among building and infrastructure projects, while “project location” was statistically significant among contractors with different years of experience. Finally, factor analysis identifies the six major underlying groups: client-related factors, bidding-related factors, contractor-related factors, market-related factors, economy-related factors, and project-related factors. The study’s findings can help contractors better understand the factors influencing their bidding-related decisions.

The purpose of this paper is to identifying organizational change management (OCM) practices that, when effectively executed, lead to increased success rates of adopting APDMs in owner AEC organizations. Design/methodology/approach: Seven OCM practices were identified through a comprehensive literature review. Then, through a survey of 140 individuals at 98 AEC organizations, the relationships between OCM practices and organizational adoption of APDMs were established. Findings: The findings indicate that OCM practices with the strongest relationship to successful APDM adoption are realistic timeframe, effective change agents, workloads adjustments, senior-leadership commitment and sufficient change-related training. Practical implications: Adopting APDMs can be extremely difficult and requires significant organizational change efforts to ensure the change is a success. Organizations that are implementing APDMs for the first time should consider applying the OCM practices that this study identifies as most related to successful APDM adoption. Originality/value: This study contributes to the existing body of knowledge by identifying the OCM practices that are most significantly associated with successfully adopting APDMs.

Increasing the concrete matrix strength of steel-fibre-reinforced concrete slab from 45 to 85 MPa had a marginal effect on the load-carrying capacity of the slab at points on the displacement response beyond the first crack point. Furthermore, the Meyerhof model was found to underestimate the load-carrying capacity of the tested ground slabs.
