ABSTRACT Despite the plethora of studies on barriers to mentoring, these have focused more on the higher education sector, and particularly mentoring to university graduates. However, there still limited studies that have focused on understanding the barriers affecting the mentoring process of graduates in quantity surveying firms within developing countries. This research aims at bridging that knowledge gap by exploring the underlying relationships among the barriers to mentoring of graduates in the context of quantity surveying firms in Tanzania thus minimizing risk of losing vital knowledge and competencies. An interpretivist epistemological design was adapted to extensively manually review and search the literature on mentoring barriers. Based on 15 barriers to mentoring identified, a questionnaire survey was used to collect data from graduates employed in Tanzanian quantity surveying firms, with 53 validated responses; mean score techniques and factor analysis were conducted. Empirical results showed a four-factor model comprising the following: multicultural and social injustice-related barriers; mentoring relationship-related barriers; personal and relational behavior-related barriers; and attitudinal and knowledge-related barriers. The identification of the key barriers to mentoring of graduates would be useful to advocate informal mentoring training programs to sharpen the skills of mentors in order to improve the performance of graduates.

ABSTRACT Effective project management of sustainable infrastructure projects is critical for successful project delivery and improved project performance of construction projects. Coupling and integrating Front-End Planning (FEP) techniques and sustainability rating systems such as the EnvisionTM rating system in the curricula can equip our construction workforces with advanced skills in planning and managing such projects. Therefore, this study investigates the existing synergies between FEP and EnvisionTM and establishes the necessity of incorporating these concepts into the Construction Management (CM) curricula. The research methodology included (1) surveying infrastructure experts to investigate the nexus between EnvisionTM credits and FEP; (2) investigating the use of pre-project planning tools in the industry; and (3) implementing a Problem Based Learning (PBL) activity to enhance construction students’ knowledge of FEP and sustainability. The results highlighted that sustainability practices greatly align with FEP. Moreover, the knowledge improvement through the PBL activity demonstrates that such an active learning method can be a strong candidate for effective pedagogical design to teach these concepts. The novelty of this study encompasses highlighting the necessity to link and incorporate EnvisionTM with FEP in construction curricula to support CM students to become adept in both planning and delivering sustainable infrastructure projects.

ABSTRACT Associations in all types of industries are required to rethink and reshape their recruitment efforts to engage the next generation of early-career professionals. Many of the things that previously attracted members don’t seem to work. This study looked at builders’ associations and how they can improve their current strategies and offerings to attract Young Professionals or those moving through the various early stages of their careers. The objective of the Delphi study conducted was to come to an expert consensus on recommendations for associations to increase membership. The results indicate associations must enhance education and exposure to young people about the industry, provide more mentorship opportunities, and encourage young people’s involvement in leadership positions.

ABSTRACT Rapid developments in building information modeling (BIM) are escalating the architecture, engineering, and construction (AEC) industry toward digital transformation. However, the lack of skilled BIM professionals is a critical issue slowing this transformation. Currently, few educational institutions include BIM topics in their curricula, especially those developed for quantity surveying (QS) programs. Moreover, the learning outcomes of BIM curricula may not meet the current industrial requirements. Thus, this study investigated the current states, gaps, and challenges of BIM education for QS practices in Hong Kong. This study conducted surveys to determine industrial requirements and a case study to examine the BIM curricula currently offered at Hong Kong educational institutions. The results suggest that the current BIM education for QS practices is in line with the pace of BIM development in the AEC industry. However, some advanced topics are not covered in BIM education. Additionally, the non-standardized BIM competencies to be attained by students lead to uncertainty and challenges in BIM education for quantity surveyors.

ABSTRACT Sitework is an essential scope of many building construction projects. The level of cognition related to sitework that a construction management undergraduate should achieve prior to entering the construction industry has not been researched. This paper describes a study analyzing both academics’ and industry practitioners’ perceptions of what construction management students should know about sitework by the time they graduate, both in terms of the topics explored and the level of knowledge they have attained. Surveys measured the level at which specific sitework topics should be incorporated into construction management programs. Responses collected from 60 industry practitioners and 35 faculty from construction management programs were analyzed. Results show that practitioner respondents generally expect graduates to exit their programs at lower levels of cognition, while academics expect graduates should achieve higher levels of cognition. A statistically significant difference exists between academics and practitioners regarding several estimating topics, as well as safety, site logistics, existing technologies, and unforeseen site conditions. Recommendations from the study regarding the level of cognition for each topic area are provided to offer the opportunity for programs to evaluate and adjust their content coverage and to suggest that further studies may be warranted based on industry perceptions.

ABSTRACT Construction workers experience a disproportionately high rate of work-related injuries. However, if hazards are properly recognized and addressed, most of these incidents are preventable. Job hazard analysis (JHA) is a method for identifying and mitigating workplace hazards that emphasizes proactive risk control. Despite its importance, the construction industry currently lacks comprehensive guidelines on how to effectively design and implement JHA on a consistent basis. To fill this gap, this case study pursued two objectives: (1) to explore challenges and shortcomings of current practices in developing and implementing JHA in construction and (2) to identify effective practices and interventions employed by contractors to address these challenges. To this end, 30 sample JHA documents were analyzed, and 23 semi-structured interviews were conducted with construction safety professionals representing 17 companies. Findings of this study identified a lack of worker involvement in the process, lack of buy-in, management absence, complacency, and inadequate coordination and communication as major issues. Solutions explored to address these challenges included incorporating visual aids, rotating JHA meeting leaders, and continuously updating JHA information to reflect the current work conditions. The practical implications of these findings and the path forward for further research are discussed.

ABSTRACT Community engagement within the construction classroom has the potential to enhance student learning while also fostering strong community relationships and meeting some of society’s most pressing needs. These activities afford students the opportunity to directly apply concepts learned in the classroom. Other outcomes include improved communication, teamwork, and the development of civic responsibility. Civic engagement through service learning qualifies as a high impact educational practice (HIP), and construction students have many options available through their applied discipline. Because of the complementary benefits to both students and the community, many universities include civic engagement as a goal in strategic plans. However, to realize successful implementation, goals at the university level need to follow through to the strategic plan goals of individual units. Starting with 106 land-grant institutions, 36 are identified as housing construction programs. Online research was conducted regarding strategic and unit-level plans, and follow-up interviews were held with 12 of the 36 schools. Results confirm and expand on the gap identified in previous research between university strategic plans and unit-level plans. With relatively small shifts, construction programs have the potential to improve student learning, the academic experience, meet community needs, and align with university strategic plans.

Concrete is the most generally used construction material in buildings,pavements, and infrastructures. Concrete is a construction materialcomposed of cement as binder, fine aggregates and coarse aggregatesmixed with water which hardens with time. Concrete is a versatileconstruction material within the housing industry of the planet. Thestandard of the concrete is tormented by various factors and from thosevarious factors which may have an effect on the concrete quality are, thecoarse combination size has its own nice role on the standard of concreteproduction. A laboratorial experiment was conducted to work out the resultscoarse aggregates size on recent and hardened concrete properties. For thisstudy totally different crushed volcanic rock aggregates sizes were collectedfrom almost Jimma city for determination of the results of coarse aggregatesizes in concrete production. Three coarse aggregate nominal sizes of 10mm, 14 mm and 20 mm were used for samples production to envision thescale effects on concrete properties. For this study the procedures that wasfollowed, the types and quantity of materials for concrete creating weresimilar whereas sizes of nominal basaltic coarse aggregate were different.The fresh concrete has a slump value of 67 mm, 72 mm and 83 mm for10mm, 14 mm and 20 mm aggregate sizes respectively. A total of thirty sixconcrete cube samples were ready and tested using compressive strengthtesting machine at totally different ages of the cube 7 days, 14 days, and 28days, to know their strengths. The compressive strength was 23.524 Mpa,22.643 Mpa and 22.41 MPa for aggregate sizes of 10 mm, 14 mm and 20mm respectively. The laboratory results show that 10mm coarse aggregatesize gave the most effective compressive strength and comparativelylowest slump at similar water/cement ratio of 0.6. At 28th day 10mmcoarse aggregate size gave 23.524 Mpa compressive strength which is themaximum compressive strength from the remainder coarse aggregates so,the optimum maximum size of coarse aggregate for this study was 10mm.

Earlier research works on fire risk evaluation indicated that an objective,reliable, comprehensive, and practical fire risk evaluation model is essentialfor mitigating fire occurrence in building construction sites. Nevertheless,real empirical studies in this research area are quite limited. This journalpaper gives an account of the second stage of a research study aiming atdeveloping a fuzzy fire risk evaluation model for building construction sitesin Hong Kong. The empirical research findings showed that the overall firerisk level of building construction sites is 3.6427, which can be interpretedas “moderate risk”. Also, the survey respondents perceived that “Restrictionsfor On-Site Personnel” is the most vital fire risk factor; with “Storage ofFlammable Liquids or Dangerous Goods” being the second; and “Attitudeof Main Contractor” the third. The proposed fuzzy fire risk evaluationmodel for building construction sites can be used to assess the overall firerisk level for a building construction site, and to identify improvementareas needed. Although the fuzzy fire risk evaluation model was developeddomestically in Hong Kong, the research could be reproduced in othernations to develop similar models for international comparisons. Suchan extension would provide a deeper understanding of the fire riskmanagement on building construction sites.

This paper is based on a scientific methodology developed by its author(1987) in his doctoral dissertation and later (2004) published in a book.According to this methodology, architecture is understood as a systemconsisting of four basic elements: Environment, Man, Boundaries andPerspectives. As a case study, this methodology was checked and confirmed(in the dissertation and in the cited book) on the example of an orientaltype town hall in Bosnia and Herzegovina, Serbia, Montenegro, Kosovoand Macedonia, and later in all published books, to date.In this paper, the author draws attention to the element of Perspective (inarchitecture) thus emphasizing its exceptional importance in understandingarchitecture as a whole. In doing so, this element cannot be separated fromthe other three elements (Environment, Man, Boundaries) since with themhe builds architecture as a single whole.
