This paper aims to explore the differences in first-year and senior engineering students’ engineering agency beliefs and career goals related to sustainable development. The authors also sought to understand how topics related to sustainable development in engineering courses affect senior engineering students’ goals to address these issues in their careers. This work provides evidence of how students’ agency beliefs may be shaped by higher education, which is essential to workforce development.

Findings stem from two national surveys of engineering first-year (Sustainability and Gender in Engineering, n = 7,709) and senior students (Student Survey about Career Goals, College Experiences, n = 4,605). The authors compared both groups using pairwise testing by class standing.

The results indicate that undergraduate studies tend to reinforce students’ engineering agency beliefs to improve their quality of life and preserve the environment. Significantly more senior students selected career goals to address environmental issues compared to first-year students. In general, students undervalue their roles as engineers in addressing issues related to social inequities. Those topics are rarely addressed in engineering courses. Findings from this work suggest discussing sustainability in courses positively impact setting career goals to address such challenges.

The study compares results from two distinct surveys, conveyed at different periods. Nonetheless, the sample size and national spread of respondents across US colleges and universities are robust to offer relevant insights on sustainable development in engineering education.

Adapting engineering curriculum by ensuring that engineering students are prepared to confront global problems related to sustainable development in their careers will have a positive societal impact.

This study highlights shortcomings of engineering education in promoting social and economic sustainability as related to the engineering field. Educational programs would benefit from emphasizing the interconnectedness of environmental, social and economic dimensions of sustainable development. This approach could increase diversity in engineering education and the industry, and by ripple effect, benefit the communities and local governance.

This work is a first step toward understanding how undergraduate experiences impact students’ engineering agency beliefs and career goals related to sustainability. It explores potential factors that could increase students’ engineering agency and goals to make a change through engineering.

The purpose of this study is to better understand the nature of graduate training experiences in research groups and to identify factors that may lead to increased student retention and success.

Surveys administered at four US universities resulted in quantitative responses from 130 Master’s and 702 doctoral engineering students participating in graduate research groups. Missing data were imputed, and responses were weighted by gender, discipline, degree program and nationality. Exploratory factor analysis identified four factors describing research group experiences. Regression models were built for two outcomes: satisfaction with research group experience and intention to complete degree. Control variables included gender, discipline, degree program, nationality, year in program and institution.

Fifty-five per cent of the variance in satisfaction was described by a model including agency, support, international diversity and group climate. Sixty-five per cent of variance in intent to complete was described by a model comprising international diversity, agency and support. Several control variables were significant.

Agency and support in particular were the most influential predictors of both satisfaction and intention, suggesting that future efforts should emphasize stable funding, clear expectations, access to mentors and agency-building experiences to help students take an active role in their own success.

This paper explores changes in the attitudes of managers at a state transportation agency towards working with professional service consultants over time. The development of a relational orientation amongst agency managers is explored, i.e. managerial styles recognizing greater interdependence and emphasizing trust, partnership and collaboration over formal procedures and monitoring. Case studies of two points in time (2003 and 2007) are presented using semi-structured interviews and survey data. The evidence demonstrates growing patterns of interdependence and the structural and procedural adaptations made by the agency. Corresponding difference in means tests demonstrate patterns of change in relational orientation over time.

The publication presents an analysis of the cost and schedule performance of incentive/disincentive projects and case studies toward developing a systematic disincentive valuation process, with Construction Analysis for Pavement Rehabilitation Strategies (CA4PRS) software integration that aids agencies in minimizing the likelihood of court challenges of disincentives.

From a California transportation database, the authors performed cost and schedule analyses of 43 incentive/disincentive (I/D) projects and case studies on four of those I/D projects. Interviewees included subject matter experts from transportation organizations to ensure applicability and maximum value-adding, and the process was implemented on ten California transportation projects and monitored for performance.

The presented process mitigates the contractor's ability to claim disincentives as penalties in a court of law through the following: (1) all calculations are performed using project-specific bases, backed by estimations of actual incurred costs; (2) the CA4PRS software allows for estimation transparency and (3) the clarity of cost inclusions reduces any chances of “double-dipping” between disincentives and liquidated damages.

Transportation agencies have historically faced legal challenges to their enforcements of disincentives. As agencies continue to apply disincentives on more megaprojects, contractors will likely attempt to pursue legal challenges more frequently. The presented process mitigates the likelihood of these challenges going to court and increases the accuracy and efficiency of disincentives.

While there have been publications that discuss the legal challenges of imposing disincentives, they mainly provide guidelines and lack applicable processes. Existing literature that does present incentive/disincentive valuation process focuses on incentive valuations and neglects the disincentives' legal challenges. The following publication fills this gap by presenting an applicable disincentive valuation process for transportation projects which incorporates the guidelines for legal mitigation.

The United States today boasts of a complex and extensive set of public and private institutions and arrangements for managing its water resources. Today's system of watershed management is neither entirely top-down nor bottom-up. It is not entirely planned, nor is it entirely laissez-faire. Rather it is a hybrid. This chapter analyzes through a historical lens how American watershed management evolved to this state. It looks at two driving factors: technological change and trends in American political culture. Technology provided the reason for water resource and watershed management to evolve because of the conflicts provoked by its unintended and negative side effects, such as pollution. American political culture mediated the way that individuals and government reacted to these conflicts and spurred the evolution of new institutions.

Why should anybody outside the USA care about the attempt to reorganize the Disability Determination Service (DDS) of the Social Security Administration (SSA)? Part of the answer to this question has to do with the assumptions and approaches which were used. In fact, the attempt to reorganize DDS is one of the first well‐documented attempts to re‐engineer a major agency in the public sector. Given the excitement in the private sector about re‐engineering and its potential and possible cost, public managers everywhere should develop a better understanding of what re‐engineering is all about. The use of a case study seems to be a promising way for framing and illustrating some of the important questions about the use of re‐engineering in the public sector.

Managers are increasingly looking to adopt the Internet of Things (IoT) to include the vast amount of big data generated in their decision-making processes. The use of IoT might yield many benefits for organizations engaged in civil infrastructure management, but these benefits might be difficult to realize as organizations are not equipped to handle and interpret this data. The purpose of this paper is to understand how IoT adoption affects decision-making processes.

In this paper the changes in the business processes for managing civil infrastructure assets brought about by IoT adoption are analyzed by investigating two case studies within the water management domain. Propositions for effective IoT adoption in decision-making processes are derived.

The results show that decision processes in civil infrastructure asset management have been transformed to deal with the real-time nature of the data. The authors found the need to make organizational and business process changes, development of new capabilities, data provenance and governance and the need for standardization. IoT can have a transformative effect on business processes.

Because of the chosen research approach, the research results may lack generalizability. Therefore, researchers are encouraged to test the propositions further.

The paper shows that data provenance is necessary to be able to understand the value and the quality of the data often generated by various organizations. Managers need to adapt new capabilities to be able to interpret the data.

This paper fulfills an identified need to understand how IoT adoption affects decision-making processes in asset management in order to be able to achieve expected benefits and mitigate risk.

This paper presents a developed spatial-temporal analysis framework for the case of investigating the business performance of construction consultancy services (CCS) in China.

The spatial-temporal analysis is based on the data envelopment analysis (DEA) technique. The spatial analysis follows the DEA results under a contemporaneous benchmark technology and a virtual decision-making unit, consisting of ranking analysis, cluster analysis and variation analysis. The temporal analysis is reliant on the DEA results under a global benchmark technology and the time value of money, including trend analysis and driving force analysis containing pure technical and scale efficiency factors.

Three CCS types in China are investigated, including engineering survey and design, construction supervision and procurement agency. The performance rank order and cluster classifications are mainly related to economic development levels. Engineering survey and design demonstrates the best performance and higher imbalances; however, construction supervision and procurement agency illustrate lower performance and imbalances. Scale efficiency significantly promotes business performance, whereas pure technical efficiency plays an inconspicuous role.

The CCS promote technical efficiency by developing their service and innovation levels. The service of engineering survey and design registered in Beijing, Shanghai and Guangdong is recommended for entering the service market in China.

The spatial-temporal analysis framework was developed, which is generic and provides a pathway to measure, compare and assess performance comprehensively. The CCS business performance is firstly measured.

This study aims to investigate ground-related design deficiencies as potential avenues of avoidable cost overruns, discernible from the geotechnical practices of highway agencies in the Niger Delta region of Nigeria.

The study deploys an interpretivist qualitative methodology to provide a detailed descriptive analysis of the design-related geotechnical practices of highway agencies during the pre-contract phase of highway projects. Semi-structured interviews were conducted with in-house professionals, consultants and contractors affiliated with the three highway agencies in the Niger Delta and thematically analysed to identify significant deviations from geotechnical best practices.

The study outcome shows that during the pre-contract phase, a chain of design-related geotechnical shortcomings has plagued highway projects executed in the Niger Delta. This view of practice uncovered in this study demonstrates a culture of significant deviation from best practice recommendations, which could plausibly contribute to the history of significant project cost overruns recorded in the region.

The study qualitatively spotlights gaps in the practice of highway agencies and reinforces the need for a re-orientation of the attitude to risk management, to give geotechnical concerns a priority in the financial management of highway projects executed in the Niger Delta region of Nigeria.

Public agencies have started to shift away from the traditional lowest responsive and responsible bid to other approaches in purchasing certain items and services. These alternative approaches emphasize the quality of the products and the qualifications of the vendors. The purpose of this article is to explore the use qualifications-based selection (QBS) and other non-traditional source selection methods in public procurement processes. An online survey was sent out to 1665 members of the National Institute of Governmental Purchasing, and a mail survey sent a random sample to 300 American Public Works Association members. The survey results show that while the traditional lowest responsive and responsible bidding is still the dominant selection method when all procurement is considered, QBS and other non-traditional methods have gained wide acceptance and use in public agencies, especially for the purchase of professional services and information technology.
