Overview of lean issues in managing the green construction project / Wan Nur Syazwani Wan Mohammad and Mohd Rofdzi Abdullah

Lean Management in construction and Green Construction approach seems to be an alternative route towards the sustainable construction. It has been introduced to minimize wastages as the main objective. Recently, a problem such as cost overruns, low productivity and quality occurs frequently in constructions that need to be addressed by the project stakeholders. The management principles and techniques such as Total Quality Management (TQM), Value Stream Mapping (VSM), Critical Path Method (CPM), Building Information Modelling (BIM), Just In Time (JIT) and 5S are some of the lean tools that are implemented to improve the construction process. Hence, through these various lean tools, it is believed that overall construction project performance will improve. This paper evaluates the issues and overview of current lean approaches in green construction agenda. The technical and human issues revealed will then be map to form the framework of implementing a Lean Management in Construction

The effectiveness of the implementation of QE/5S towards quality environment at workplace / Norhaslina Jumadi ... [et al.]

Since many organizations attempt to become the best in their service, a good management system is required and therefore, the implementation of 5S is highly recommended. 5S is known as the 5 pillars which refer to sort, set in order, shine, standardize, and sustain (Hirano, 1995). This system is a good starting point for all improvement effort and maintaining work efficiency by the staff. The application of 5S at workplace will also help in improving safety, work efficiency, productivity and a sense of ownership. However, the implementation of 5S demands a huge commitment from the top management and participation by everyone in the organization is required. UiTM (Perak) is an educational institution with almost 200 administration staff in the administration building. Since 2012, UiTM Perak has gained recognition and 5S certification from Malaysia Productivity Corporation (MPC) for the commitment of QE/5S practice at workplace. This paper attempt to discover the significance 5S implementation in a workplace and to identify the impact of the elements in 5S towards quality environment among UiTM (Perak) administration staff. A structured questionnaire was distributed randomly among UiTM staff. Data from the questionnaire was analysed using the SPSS. While for secondary data, multiple case study and literature review from various organizations were analysed qualitatively to see the gap and the best practice in sustaining the implementation of QE/5S. This research is hoped to contribute to the knowledge of the importance of QE/5S implementation and would strongly support the objectives of organization to achieve continuous improvement and quality environment in workplace

Aligned magnetic field of two-phase mixed convection flow in dusty Casson fluid over a stretching sheet with Newtonian heating

The effect of aligned magnetic field is numerically investigated for mixed convection flow of dusty Casson fluid over a stretching sheet. The governing equations of flow and heat transfer for the two-phase model (fluid and dust) with an appropriate thermal boundary condition which is Newtonian heating (NH) is presented. The similarity transformation is employed to transform the nonlinear governing equations for each phase into the ordinary differential equations which then solved numerically using Runge-Kutta Fehlberg (RKF45) method. Numerical solutions obtained for velocity and temperature distributions are illustrated through graph by varying several physical parameters. It is observed that the fluid velocity decreases with an increase in aligned magnetic field and particle-fluid interaction parameter

Properties of Recycled Aggregate Concrete Reinforced with Polypropylene Fibre

This research work is aimed to investigate how the addition of various proportion of polypropylene fibre affects the mechanical strength and permeability characteristics of recycled aggregate concrete (RAC) which has been produced with treated coarse recycled concrete aggregate (RCA). Further research on RAC properties and their applications is of great importance as the scarcity of virgin aggregate sources in close proximity to major urban centers is becoming a worldwide problem. In this study, the hardened RAC properties at the curing age of 7 and 28 days such as compressive strength, flexural strength, ultrasonic pulse velocity (UPV), water absorption and total porosity were evaluated and compare with control specimens. Experimental result indicates that although the inclusion of the treated coarse RCA can enhance the mechanical strength and permeability properties of RAC, Further modification by addition of polypropylene fibre can optimize the results

Aligned Magnetic Field on Dusty Casson Fluid over a Stretching Sheet with Newtonian Heating

Boundary layer flow and heat transfer on Casson fluid with dust particle over a stretching sheet is numerically investigated. The influences of aligned magnetic field together with Newtonian heating are considered in this problem. The governing equations are first transformed into ordinary differential equations using the appropriate similarity transformation variables. The numerical computation using Runge-Kutta Fehlberg (RKF45) method is employed to generate the results. Several physical parameters for both phases (fluid and particle) such as aligned angle, magnetic field parameter, Casson parameter, fluid particle interaction parameter, Prandtl number and conjugate parameter are investigated and analysed. The results in term of distribution velocity and temperature are presented graphically. The finding revealed that a rise in aligned angle and magnetic field parameter led to decrease the velocity profile and increase the temperature profile for both phase

Influence of radiation and viscous dissipation on magnetohydrodynamic Jeffrey fluid over a stretching sheet with convective boundary conditions

The present paper focuses on the influence of radiation and viscous dissipation on magnetohydrodynamic (MHD) flow and heat transfer of a Jeffrey fluid over a stretching sheet with convective boundary conditions (CBC). The governing equations are reduced to non-linear ordinary differential equations by using similarity transformation variables and then solved by using Runge-Kutta-Fehlberg method. The results generated from the numerical computations are presented in the form of tables and graphs for some values of Deborah number, ratio of relaxation to retardation times, Eckert number, radiation parameter and magnetic parameter. It is found that the distribution of fluid velocity is noticeably increased with an increment in Deborah number while the distribution of temperature shows the opposite trend
