Time delays and cost overrun are still a "scourge" in construction projects. The most important factors that cause these two risks are ineffective project planning and scheduling, and inaccurate quantity taking off. Thus, it is most appropriate to carry out mitigation since the project planning period. With the fact of increasing stadium construction in various countries, with iconic and futuristic design, and containing national pride, must be a serious concern so that the risk of time delay & cost overrun can be reduced. Because stadiums are like that usually involve a complex structural system, complicated installation technique with strict network diagrams. The M-PERT & BIM 5D - Based Quantity Take Off method has the potential to mitigate and minimize this risk. This study, with the RII simulation, reveals the critical success factor for applying the potential of this method, especially in stadium structural work. These factors can become a serious concern for construction practitioners, especially in Indonesia, who are and will build stadium projects. Keywords: Structure; Stadium; M-PERT; BIM 5D; RII.

Planning and scheduling is extremely important role in construction projects thank to the increasing difficulties during this field. Construction Planning is that the necessary warning to Scheduling and determining general sequence, defining labour tasks, construction methods and assigning responsibilities, inappropriate planning can cause major delays with the project work. For the planning and scheduling work requires huge amount of  paperwork, which makes the management very burdensome. These problems may be solved employing a  project management software which helps to grant a planned approach to planning. Nowadays use of project management (PM) software as a tool for managing and organizing work has gained its importance in construction industry and continues to grow at a faster pace in other industries also. During this study, attempt is made  to check project management software such as MS project and Primavera and their feasibility is studied.

Methods of simulating offshore construction project activities and associated weather-related downtime are reviewed. Specific attention is given to the use of network modeling techniques to determine probable durations and risk levels for complex marine projects such as the installation of the first guyed tower production platform, and offshore mating of HIDECK, a barge-mounted integrated oil production facility with a preinstalled platform. Monte Carlo simulation techniques are used to select random variables. The environmental data derived from a spectral ocean wave model are used, while full account is taken of hydrodynamic response of the offshore systems in order to establish the limiting sea states for performing specific construction operations. Environmental data sources for such simulations are reviewed. Various methods used to determine limiting sea states are compared. The results of statistical analysis of offshore construction operations, such as module lifting, pipelaying, and saturation diving, are presented to give insight into the limitations on vessel motions during offshore construction. In summary, this paper provides a review of methodologies and data used in performing operability analyses, in order to assist engineers in assessing duration and risk for offshore construction projects.

During the last decades, the introduction of Building Information Models (BIM) has opened new possibilities to ensure better communication and a shared understanding between stakeholders in construction projects. Similar benefits have been found in 4D simulations of the schedule. While BIM and 4D use has seen a steady increase, the potential benefits have not fully been realised, primarily due to tools not supporting and enabling the full potential of collaborative stakeholder involvement in scheduling. The benefits of 4D simulations come from improving communication between stakeholders. While traditional 4D modelling connects an existing BIM model with an existing schedule, a move from this type of passive 4D visualisation toward social co-creation enables all stakeholders to be involved in the scheduling process. This connection is further enhanced with the use of Virtual Reality (VR). Recent research has shown VR to enhance understanding and perception of the space and details and, thus, a better understanding of the project. This paper maps collaborative planning and scheduling method and traditional 4D scheduling using process modelling. This mapping is followed by implementing the 4D collaborative planning and scheduling method in the virtual project planning system with support for a multi-user interactive VR environment. The system enables social co-creation both during the planning and scheduling and during 4D modelling; it improves understanding of the project and the planning and scheduling.

There are many factors that contribute to the causes of schedule overruns in construction projects. This ranges from factors inherent in the technology and its management, to those resulting from the physical, social, and financial environment. Schedule overruns can give rise to disruption of work and loss of productivity, late completion of project, increased time related costs and third party claims and abandonment or termination of contract. Schedule overruns are costly and often result in disputes and claims. Hence, the need to identify mitigation measures of construction projects overruns that will bring about the timely delivery of construction projects. This paper assesses the measures to mitigate against construction projects schedule overruns in the Gauteng Province construction industry in South African. The data used in this paper were derived from both primary and secondary sources. The primary data were collected through a questionnaire distributed to construction professionals in the study area. Data received from the questionnaires were analyzed using descriptive statistics procedures. Findings revealed that proper project planning and scheduling, effective strategic planning, site management and supervision, amongst others, were the major mitigation measures of construction projects schedule overruns in the Gauteng Province of South Africa. This study contributes to the body of knowledge on the subject of the measures of mitigating against construction project schedule overruns in the Gauteng Province construction industry.

PurposeThis study highlights the findings of an empirical study to investigate waste factors (WFs) affecting the performance and delivery of construction projects in developing countries. The objectives of this study are to identify non-physical WFs in developing nations and rank the identified factors based on their degree of influence on the key performance indicators (KPIs) of cost, quality and time.Design/methodology/approachIn total, 34 WFs were identified through a detailed literature review and consolidated using semi-structured interviews with construction practitioners. The statistical analysis involved a normality test using the Shapiro–Wilk test to determine if sample data have been drawn from a normally distributed population, ranking the WFs using the Frequency Index (FI), Severity Index (SI) and Importance Index (IMPI), ranking the WFs based on their effect on the project KPIs of cost, quality and time, and identify clustering structures for the identified WFs to using factor analysis (FA).FindingsThe results revealed ineffective planning and scheduling, rework/repair of defective work and resource quality problems (human, material and equipment) as the three most important WFs affecting construction projects. The factor analyses showed that WFs can be grouped into five interrelated components, suggesting the need for integrated and holistic strategies to overcome the identified WF.Practical implicationsUnderstanding the effects of WFs on construction projects is a first step towards designing holistic solutions to ensuring projects deliver value to the clients and other stakeholders. The findings of this study provide direction to construction practitioners on where to focus appropriate strategies to manage the identified WFs effectively and, therefore, improve the productivity of construction projects.Originality/valueThis study provides the first holistic analysis of WFs affecting the productivity of construction projects in developing countries.

<p>Accurate information of locations from visual aspect is vital for efficient resource planning and managing the workspace conflicts in the earthwork operations, which are missing in the existing linear schedules. Hence, the construction managers have to depend on the subjective decisions and intangible imagining for resources allocation, workspace conflicts and location-based progress monitoring in the earthwork projects. This has caused uncertainties in planning and scheduling of earthworks, and consequently delays and cost overruns of the projects. To overcome these issues, a framework of computer based prototype model was developed using the theory of location-based planning. This paper focuses on the case study experiments to demonstrate the functions of the model, which includes automatic generation of location-based earthwork schedules and visualisation of cut-fill locations on a weekly basis. The experiment results confirmed the model’s capability in identifying precise weekly locations of cut-fill and also visualising the time-space conflicts at the earthwork projects. Hence, the paper concludes that the model is a useful decision supporting tool to improve site productivity and reduce production cost of earthworks in the construction projects like roads and railways. </p><p><em>Journal of Advanced College of Engineering and Management, Vol. 1, 2015</em>, pp. 75-84</p>
