© 2019 American Society of Civil Engineers. Workforce planning in the construction industry too often ignores the symbiotic relationship between employee and employer objectives by overly concentrating on corporate objectives such as maximizing productivity at the expense of construction workers' career development needs. Overall, the consequence of this approach is suboptimal performance. To address this problem, this paper presents an innovative multiobjective model that enables managers to optimize the relationship between these interdependent corporate priorities. The proposed model was implemented and solved using mixed-integer nonlinear programming on a case study involving the allocation of tasks to employees with different skill levels in a multidisciplinary engineering consulting company. While leading to a small loss of productivity, the results show a significant improvement in the career development of workers compared to conventional productivity-oriented workforce planning models, with on average 8.6% improvement in employees' closeness to their ideal skill set. Furthermore, the model produced Pareto-optimal points and a Pareto curve that enabled client-model users to select optimum job allocation based on their preferences. This research represents a paradigm shift toward a new class of socially responsible workforce planning models in which the objectives of both employees and employers are optimized.

© 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.

Workforce planning plays a pivotal role in smooth execution of construction projects. The growing challenges faced by the construction industry related to skill shortage, aging problem, and workforce attraction, retention, and buy-in have added to technical complexities of workforce planning. Nevertheless, the available workforce planning techniques are either qualitative or lack a strategic perspective that accounts for the above challenges in hiring workforce, leading to suboptimal decisions with regards to hiring and unplanned firing. This paper proposes a novel framework for optimization of hiring and firing decisions by accounting simultaneously for organizational human resource (HR) strategies, labor rights, and technical and managerial constraints of a construction project. The framework starts by setting the model parameters and the decision-making criteria using the information made available by building information modeling (BIM), project performance database, and contractual and legislative documents. It then identifies the optimal mode and duration of the employment for the workers with different skills, skill levels, and multiskilling capabilities using a dynamic programming algorithm. The application and advantages of the proposed framework are demonstrated using a case study

© 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...

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.

Construction industry is the largest global consumer of materials. This huge share comes with the huge responsibility to account for economic, environmental, and social impacts associated with the materials through adoption of sustainable procurement strategies. Sustainable material procurement requires reconciliation among economic, environmental and social impacts of procurement decisions throughout the life cycle of materials. However, this is challenging mainly due to the broad range of economic, environmental and social impacts associated with different stages of material's life cycle as well as the overlapping impacts that various supply decisions may have on multiple performance areas. Current practices of material procurement are, on the other hand, predominantly influenced by economy of construction stage and little attention is paid to environmental and social considerations over a long-term horizon. Moreover, material supply decisions made currently in practice are commonly traditional and tend to largely overlook the opportunities made available by advances in material science, computing, and decision-making areas. This chapter starts by presenting an overview of sustainability challenges associated with current material procurement practices to highlight the need for adoption of new sustainable approaches and technologies. It then continues by highlighting the challenges associated with adoption of new approaches and the important sustainability criteria to be considered in selection of new sustainable materials, technologies, and procurement strategies. A comprehensive decision-making framework for identifying the most sustainable procurement options in a construction project among various procurement options available is then presented. The framework is founded on the concepts of life cycle thinking and supply chain structure which are incorporated in to a computational module to compare the life cycle impacts of various supply decision based on th...

The job allocation models used in construction projects have been designed mainly to meet the objectives of the employers such as maximizing productivity and tended to pay inadequate attention to meet the needs and objectives of construction workers. Meeting the objectives of workers, however, is a basic component of corporate social responsibility and vital to improve job satisfaction among construction workers. Among various items on wish-list of workers, availability of career development opportunities in projects stands out as a key factor affected considerably by job allocation decisions. This paper presents an innovative mathematical model for optimization of task allocation in construction projects to maximize the availability of career development opportunities to individual construction workers, paving the way for their career development. A Euclidean distance function in n-space is specified as objective function of career development which measures and compares the distance between ideal skill levels of employees to initial skill levels and developed ones after job allocation. The proposed model is applied to an illustrative case project involving the allocation of tasks to workers with different skill levels in a construction contractor company. Results show a successful task allocation which has contributed to workers' occupational development and made them closer to their ideal skill level.

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.
