© 2017 Elsevier B.V. Safety management is regarded traditionally as an aggregate attribute for Human Resources (HR) in which the focus is placed on safety of construction crew by assuming same behaviour, capabilities and thus level of exposure to risk for all workers in the crew. In line with this, a team-based approach is generally adopted for task assignment to workers in construction operations. However, this approach tends to disregard the differences between skill level, experience, capabilities, learning rates and fatigue rates of different individual workers forming the team. In particular, due to differences in visual, auditory, cognitive and psychomotor capabilities of different workers and brain resource demands of different activities, the traditional approach may result in inconsistent workloads and uneven fatigue rates within a crew, affecting the workers' and crew's safety negatively. This paper proposes a novel framework for task assignment to construction workers in which safety of individual workers and thus the crew is ensured through optimizing workload distributions within a crew. The framework computes visual, auditory, cognitive, and psychomotor requirements of the jobs assigned to a worker and minimizes the identified workload imbalances through collaborative execution of shared tasks. The application of the proposed framework is examined on a pipe spool fabrication operation of a refinery project in a simulation environment.

© 2018, Emerald Publishing Limited. Purpose: The short life cycle replacement of fitout in modern high-rise office buildings represents an under-researched waste problem. This paper aims to quantify the amount of demolition waste from office strip-out including attention to waste streams going to landfill, reuse and recycling. Design/methodology/approach: Quantitative waste data (by weight) were measured from 23 office fitout projects situated in 'A' grade office building stock from the Sydney CBD. Waste streams were measured separately for landfill, reuse and recycled materials. Descriptive and clustering statistics are presented and analysed. Findings: From a total of 9,167 tonnes office fitouts demolished, 5,042 tonnes are going to landfill. The main contributor to landfill stream is the mixed waste generated in a fast-track demolition process. This approach partly resulted from the office interiors lacking regularity and easy disassembly. Moreover, considerable variability is observed in the waste per area, the waste streams and the waste compositions. Also, it is noteworthy that the recycled waste stream considerably increases when there exist economically viable conversion facilities, as for metals, hard fills and plasterboards. Research limitations/implications: The research is focused upon work practices that take place in Australia; therefore, generalisability is limited to situations that have similar characteristics. Future studies are needed to verify and extend the findings of this research. Practical implications: A key area arising from the research findings is the need to design fitout with recycling and reuse in mind to divert more from landfill. This must explore and incorporate onsite demolition processes to ensure the design is well suited to commercially dominant processes in the overall demolition process, as well as attention to developing economies of scale and viability in re-sale markets for reused items. Originality/value: Little empiri...

© 2015 American Society of Civil Engineers. The presence of multiskilled workers in a crew can increase the crew's productivity through reducing inefficiencies and supervision requirements, while also providing on-the-job learning opportunities for single-skilled workers. The effect of the presence of multiskilled workers on the learning rate of workers, which is also a function of skill level and experience, and thus on the crew's productivity, is especially significant in repetitive construction projects. This paper presents a mathematical model for identifying the optimal combination of single-skilled and multiskilled workers with different levels of experience in the crew to minimize the duration of construction projects by accounting for the overlapping effects of multiskilling, skill level, and learning on the crew's productivity. The model is applied to an illustrative case project to demonstrate the practicality of the model. The optimum crew compositions for different activities involved in the case project are identified using a solution technique which combines constraint programming (CP), statistical analysis (SA), and a genetic algorithm (GA).

Off-site transportation of construction materials is planned commonly by considering the transportation costs as the dominant
decision variable. Despite the significant impact of delays in the delivery of materials on the progress of projects, there is a lack of a systematic
approach to estimating the off-site transport time of materials by considering the material characteristics and logistics options. This paper uses
the results of a case study to highlight the importance of accounting for off-site material transport time in the planning of an industrial
megaproject where small delays in activities requiring diverse materials could significantly delay the progress of the project, leading to
considerable financial loss in some cases. In addition, a framework is proposed for estimating the duration of off-site transportation in industrial
megaprojects by categorizing construction materials based on their supply chain structure and accounting for the effects of the
transport mode, size, and weight of consignments. The results of the case study indicate that adjusting the logistics variables based on
the results of a statistical analysis on transportation monitoring data collected in the earlier stages of a project may lead to a reduced delay
in off-site transportation in subsequent stages.

The existing approaches towards interactive student feedback and question collection have two major
drawbacks. First, instructors are only provided with generic feedback, typically at the end of a teaching
period. Second, students are not provided with opportunity to give content-specific feedback or raise
questions on specific sections of content during the lecture. The latter is especially important in large
classes with students from non-English speaking background who are generally less likely to actively
participate in discussions.
This paper aims to develop and test a user-friendly and automated platform, with efficient data
management structure, which facilitates real-time collection and addressing of students' feedback on a
specific part of topics discussed during the class.
A web-based software has been developed using annotation technologies which assists students in
providing anonymous and content-specific comments on lecture materials. The software equips
lecturers with a real-time platform for retrieval of comments classified based on their area, type and
frequency. The platform contains features that enable users, teachers, for analytical assessment of
both teaching and learning performance.
The trial use of the designed platform has primarily increased engagement of students in the class
discussions. This trend is specifically observed amongst international students who have gained
confidence to raise more questions, compared to the traditional teaching methods. Concurrently, the
lecturer has dramatically decreased his response period to students' queries to nearly real-time
through receiving classified comments adhered to a particular part of the lecture.
The software allows for structured analysis of course materials and students' feedback which can be
further used to update teaching standards. Moreover, it improves teacher-student relationships
through timely and purposeful addressing of instructional...

Assignment of jobs to a construction crew is not a trivial task. The optimal job allocation should consider the characteristics of workers as well as brain resource requirements of the job. Failure in proper allocation of jobs to workers can lead to an inconsistent workload distribution among workers which can then results in a decrease in the overall productivity. The inconsistency in the workload of workers can cause imbalanced fatigue rates and skill level stagnation particularly for workers who are less involved. This paper proposes a framework for regulating job allocation to workers by accounting for workloads and characteristics of worker. Workloads are attributed to visual, auditory, cognitive, and psychomotor brain resource requirements of different tasks. To achieve a realistic assignment of jobs, the framework incorporates workers' capabilities in terms of skill type and skill level. Workforce management strategies established by a contractor, including safety improvement, skill enhancement, and multiskilling, determine approaches toward minimizing workers' workload variance within a crew. Application of the proposed framework is demonstrated using a real case concreting project with a simple trial modification in task assignment process under 'safety improvement' strategy.

Iran is engaged in a long-term program to improve and strengthen its position among producers of petroleum in the world. In this regard, many projects are planned and executed in different fields related to oil and gas industry. Prior to investment in new projects, it is essential to understand and manage major corporate risks and their related consequences. Due to nature of petroleum industry, Health, Safety and Environmental (HSE) issues are associated with such projects and have always been matters of concern. This paper directs readers towards the integrated HSE approach from concept to affect project construction phase. The process of oil production includes exploration, extraction and transfer of oil and gas to refining and processing facilities. In this study, petroleum industry projects are divided into main categories and compared based on different characteristics. Then, risks related to HSE issues are identified by conducting interviews. Finally, risks' impacts are assessed by considering characteristics of the projects. In this research, the risks related to HSE issues of oil industry projects are classified into eight groups including disease, accidents and injuries, natural disasters, climatic condition, stakeholders, rules and regulations, environmental constraints, and cultural issues. Importance of the identified risks is determined through considering their relationship with various aspects of the different characteristics of projects. Investigations show that geographical situation, centralization status, and construction method of projects are the key dynamics for resolution of the risks.
