One drawback of the Line of Balance (LOB) method is the unavailability of commercial software featuring its fundamentals. Studies pointed out this drawback as a factor that prevents a more frequent use. Recognizing the potential of the LOB method for managing construction projects, the objective of this paper is to propose a methodology for modeling Line of Balance schedules using CPM software like MS Project®. Previous researches developed an integrated Critical Path Method (CPM) and LOB model in an analytical nongraphical manner. This paper advances LOB modeling one step further to deal with other possible logical dependencies between activities. The presented framework can be used to develop a scheduling model that can link input and output data to commercial scheduling software; MS project®. The results of model application on a case study show the model ability in dealing with all possible relations with lags between activities and data transfer to MS project®.

A well-planned construction schedule not only helps in outlining the pace of work but also how the work will get done. Two different kinds of project scheduling methods are employed for a sample road construction project; Critical Path Method (CPM) and Linear Scheduling Method (LSM). The aim of this study is to briefly evaluate and compare network programming techniques and linear scheduling techniques for a sample road construction project, by comparing Critical Path Method (CPM) and Linear Scheduling Method (LSM).

Construction projects are often criticized for over running time and cost. Previous studies often identified ineffective planning and scheduling as the most frequently cited cause of delay. Schedule development usually starts in the tendering stage of projects and gets further developed upon contract award to establish project baselines. They are subsequently used for planning work along with the required resource, progress monitoring and reporting, forecasting and determination of extension of times, if necessary, for completion. Problems that become apparent during the assessment of construction claims and disputes emphasizes the importance of producing high-quality baseline schedules. Several criteria have been identified to measure schedule quality through various initiatives and models. This study critically reviews existing schedule quality assessment models in the literature; outcomes of the review are used as the basis for interviews with industry professionals to identify potential areas for enhancement. There were 23 established criteria validated by questionnaire with 47 participants. Survey results indicated a high level of agreement with the defined criteria. These factors are ranked according to their relative importance. Rank correlations between owners, consultants, contractors and subcontractors are then conducted to measure the degree of rank correlation between different parties. The results suggest that contractual measures are of the highest rank and duration estimation comes second. In addition, a high degree of ranking correlations between all parties is observed.

To protect workers' safety and health at the construction site is becoming a core value of the construction site. A safer working environment is created when risk factors on site work are recognized in advance. This study targets the worker's 1-day cycle activity in Linear Scheduling. In addition, this study suggests a Bayesian network model that presents risk factors and probability of accidents. Accidents come down to a final disaster through causal relationship from various existing risk factors. The physical risk factors of the workspace are the most direct cause of accidents. This study uses the Bayesian network model to compare the probability of accidents caused by changes in the safety environment of the work from the risk factors that have been eliminated and those that have not been eliminated. Statistical probability values confirm that accident risks can be remarkably reduced when all possible risk factors are reviewed and eliminated in advance.
