ABSTRACT Construction organizations should always look for areas of improvement. Managing risk effectively on construction projects demonstrates expertise, improves customer satisfaction, and increases the likelihood for future work with the client. Construction organizations can improve risk management by measuring their perceptions and practices with identifying, analyzing, and managing risk, also known as risk maturity. Effective measurements will lead to the identification of strengths and weaknesses and can lead to improved performance. Risk Maturity Models (RMM) have been developed in the past to measure risk management practices and perceptions. These previous RMMs were developed in industries outside of construction management. This study aimed to validate the necessary elements for measuring construction risk maturity with industry risk management experts. A three-round Delphi method study was conducted with 28 construction risk management practitioners. The study resulted in a consensus of the key elements for measuring risk maturity. Twenty-five elements were identified and ranked in order of importance. New elements with risk maturity were identified in this study that were not observed in previous RMMs and are unique to the construction industry. All elements were combined to develop the Construction Risk Maturity Assessment (CRMA) for measuring and improving risk maturity in construction organizations.

ABSTRACT As the progressive design-build (PDB) delivery method is gained traction in the construction industry, owners are interested to understand the factors that govern performance in such projects. This study examined the impact of variables such as time of involvement, team selection, and team behavior on project performance for projects delivered using the PDB method. To achieve our goal, the research team first compiled a database of 19 completed PDB projects and analyzed the data using Mann–Whitney U test. The significant results of the statistical analysis provided a list of best practices owners can follow to increase their chances of achieving success in PDB projects. Within academia, this study contributes an early performance database for assessing PDB projects. Within industry, practitioners will benefit from the results, which identify best practices for maximizing success in PDB projects and provide guidelines for using PDB as a delivery method, based on owner and project characteristics.

ABSTRACT Teamwork and participatory management techniques, such as quality circles (QCs), have positive impacts on employee JS. Nevertheless, literature has ignored the use of QCs to enhance JS in the construction industry. Thus, this study aimed to explore the influence of QCs on the JS of employees working in the construction industry in Sri Lanka. The exploratory nature of the study required data collection through semi-structured interviews, conducted in two rounds. The collected data were analyzed using code-based content analysis. The interviewees selected using purposive sampling, were holding managerial positions in construction organizations. The symptoms and causes of poor employee JS in the construction industry were identified; the QC objectives that can address poor employee JS were also analyzed. The study findings indicated that QCs are effective in enhancing the JS of construction employees.

Article history Received: 7 May 2021 Accepted: 21 May 2021 Published Online: 10 June 2021 It is possible for cost professionals to prepare an informed and compendious cost plan by identifying all the factors that cause cost overruns, variations, safety hazards and others without having a significant prior experience. The implementation of Extended Reality can address this phenomenon. The paper aims to introduce the concept of Extended Reality in the field of quantity surveying by exploring its untapped potential and also looks to identify critical barriers in implementing this technology. A detailed review of literature study produced eight critical factors acting as barriers in successful implementation. With the suggestions from the industry professionals, the inter-relationship among these factors were established and prioritised using Interpretative Structural Modelling (ISM) tool. Further, these factors were categorised using MICMAC (Cross-Impact Matrix Multiplication Applied to Classification) analysis. This study identifies, lack of expertise and lack of suitable software as the key driving factors in successful implementation and all the remaining factors are directly or indirectly influenced by them. The sample size considered in building the ISM network is limited to the Indian construction industry. The disadvantages of Extended Reality have not been covered in the study. There may be several negative repercussions to human health due to this technology. This study can be used by industry professionals in understanding how advance technology like this can overcome many challenges pertinent to cost planning and estimation. This study stands out among the few research topics which contribute to reducing the knowledge gap among the cost professionals irrespective of their experience.

Article history Received: 20 May 2021 Accepted: 26 May 2021 Published Online: 10 June 2021 Weak soils, such as soft clay and loose sand, have a poor bearing capacity, making them incapable of bearing the load of superstructures that will be imposed on them. As a result, engineers must have a solution to the issue of poor bearing capacity in weak soils before embanking into building on them. This paper reviewed the use of stone columns, piled rafts, and geogrids for improving the bearing capability of weak soils. Important findings from recent research are also discussed. From the review of the previous researcher’s findings, it was found that modelling approaches such as physical modelling (full scale, centrifuge, laboratory scale) and numerical modelling are used to study bearing capacity improvement.

ABSTRACT Virtual Reality (VR) allows for an active learning environment that can enhance a student’s comprehension of material. This research explores the actual and perceived benefit of introducing a VR simulation into a materials and methods of construction course in undergraduate education. The study included the development and implementation of a virtual simulation environment to support learning in the materials and methods of construction course. Actual student performance was then compared between a control group, who did not use the simulation, and the intervention group, those who used the simulation. Other factors such as student self-efficacy, learning motivation, and technology acceptance for the intervention group were also examined. Findings suggest that students who utilized the simulation have a better understanding of the course material represented in the simulation compared to those that were only exposed to traditional course materials.

The material was applied to increase the compressive strength of concrete strength. This material could be the demanding material for partial replacement for cement. The study observed the behaviour of the material from experts that applied these material through experimental investigation, but the study monitored the behaviour of this material by applied modeling and simulation to determine other effect that could influence the behaviour of these materials in compressive strength. This was to determine the significant effect on the addictive applied as partial replacement for cement. Lots of experts have done works on fly ash through experiment concept, but the application of predictive concept has not been carried out. The adoption of this concept has expressed other parameters that contributed to the efficiency of wood and fly ash as partial replacement for cement on self compacting concrete. The study adopting modeling and simulation observed 10 and 20% by weight of cement as it is reflected on its performance in the simulation, from the simulation wood recorded 10% as it was observed from the growth rate of this self compacting concrete reflected from the trend. The simulation for model validation was compared with the works of the studies carried out [20]. And both values developed best fits correlation.

Article history Received: 12 April 2021 Accepted: 27 April 2021 Published Online: 8 May 2021 This paper monitors the growth rate of tensile strength under partial replacement of locally sourced materials. The study monitors the behaviour of tensile between seven and twenty eight days of optimum curing age, modeling and simulation were applied in the study, whereby parameters that generate the attained tensile strength from self compacting concrete were monitored considering various factors such as variation of compaction and water cement ratio. The reaction of these parameters was examined in the study through the simulation. The reflection of these parameters influence was observed in all the trend. The study examined the level of significance of tensile on concrete structure, and therefore tries to evaluate various reflection effect from permeability and other parameters that were not considered in experimental process. These are developed from self compacting concrete partially replace cement with fly ash and wood. Tensile strength is an important property of concrete due its level of vulnerability to tensile cracking base on different kind of applied loading itself. The influence of permeability as a physical property has definitely affected the durability of concrete. These were observed on the its reflection on tensile strength in all the trend. The rate of permeability effect on tensile was monitored to reflect its reaction through microstructural perspective influence from porosity, pore size, connectivity including its rates of bonding. These correlation includes air content and capillarity. There rate of permeability coefficient on its reduction is determined by the decrease in porosity and void ratios from concrete compaction rate. It is reflected on its variation of tensile strength in self compacting concrete. The rate of permeability reducing at constant rates determined the tensile strength through it microstructural setting on the self compacting concrete. These conditions were applied on the simulation to generate the predictive values compared with experimental values by an expert [22], while an improvement was made on it study. These include monitoring of concrete permeability and void ratios effect on tensile, the behaviour of porosity under the influence of permeability and variation concrete void were examined from the permeability influence on tensile strength.

ABSTRACT This study examines the entire life-cycle of best-value projects to identify factors that can help key stakeholders build collaborative teams. Fifteen design-build projects (three medical, five offices, four educational, and three lodging buildings) that were procured using best-value were selected. For each project, knowledgeable stakeholders (i.e., owner’s representatives and contractors) were interviewed. The interview data were coded and analyzed to develop a grounded theory where forming a collaborative team is the core element. This study found that the following factors impact the degree of success achieved through the implementation of best-value: early involvement of key stakeholders, collaborative problem-solving, co-location, sharing information using technology, providing early project planning that includes clear definitions of each party’s responsibilities, building trust between parties, maintaining continuous dialogue through regular meetings, and having joint risk management. As far as academia is concerned, this research is one of the first studies that uses grounded theory qualitative method to better understand the role of project procurement on team behavior. The findings of this study can help practitioners and researchers leverage best-value procurement approach to build high-performance teams during design-build projects.
