As a result, the execution of a construction project is subject to numerous constraints that limit the initiation or progression of field operations, which invariably have a significant negative impact on the overall project performance. By definition, constraints refer to any conditions, such as time/spatial limitations and safety/quality issues, that may prevent a project from achieving its objectives. Successful execution and control of a construction project relies on the effective identification and management of constraints through master planning and short-term preventative planning. While master planning provides an overall view of a project and the overall execution strategy, preplanning offers a detailed account of operational constraints and a detailed plan showing the work to be accomplished in a relatively short time frame. Ideally, these detailed programs should reflect actual field conditions and provide field personnel with operational instructions free of constraints and conflicts (Hinze 2008). This advance planning and constraint analysis procedure is also a critical component of the last-planner methodology proposed by Ballard (2000). This research project will provide an overview of state-of-the-art schedule constraint analysis practices during look-ahead scheduling. Furthermore, it will propose a conceptual framework for managing constraints. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an Original EssayShort Literature ReviewA preliminary literature review shows that previous studies are mainly focused on understanding and modeling a particular type of constraint, such as technological, contractual, resource, space and information constraints. Limited progress has been made in comprehensively classifying various constraints based on their characteristics. In terms of modeling and constraint resolution, various approaches have been recommended. For example, many CPM-based methods are applied to handle time constraints; knowledge-based systems were used to automate work plan generation; network-based optimization algorithms were developed to resolve the constraints; and databases and visualization techniques, such as 3D, 4D, and virtual reality (VR), are used to communicate and visualize constraints. What is missing in previous studies is a comprehensive and structured approach in managing constraints. Research problem (explain the particular topic you wish to study). The importance of developing a reliable, constraint-free work plan has long been recognized by the industry. However, many construction projects are still plagued by delays and cost overruns, which can often be traced back to ineffective identification and management of constraints. First, when a constraint is not correctly identified during planning, subsequent conflicts in the field are inevitable. Today's projects are becoming increasingly technically and logistically complex, which exposes construction operations to even more complex constraints. Secondly, traditional planning methods, bar charts and the Critical Path Method 2011
