plan, providing more illustrative site layout as well as site status information.[2] ABSTRACT Construction activities need adequate workspaces to be executed safely and minimize workspace conflicts leading to safety hazards This study aimed to build a process of applying Building Information Modeling (BIM) to manage construction workspace, thereby supporting safety management The first step of the process was to build a 4D BIM model including schedule and workspace of the construction activities Then, this 4D BIM model was used to detect workspace conflicts among activities, from which the safety engineers can provide appropriate solutions timely This process helps the safety engineers make a safety plan visually and update safety information on the construction site promptly Construction activities need adequate spaces to be executed safely, called workspaces The workspace is considered both as a resource and as a constrain in safety planning and project scheduling On the construction site, the workspaces are constantly changing The location and the size of these spaces change in three-dimensional space over time Unreasonable workspace planning will result in time–space conflicts or in other words, workspace conflicts Workspace conflicts can lead to labor productivity loss and safety hazards[3] Workspace conflict could be removed to help ensure occupational safety on the construction site only when we could apply automated tools to identify, assess and analyze it CCS Concepts • Computing Simulation➝ Model methodologies 4D BIM can simulate and analyze workspaces so that can minimize workspace conflicts for construction activities during construction planning and safety planning phases This helps to assure occupational safety and productivity.[4] methodologies➝Modeling and development and analysis-Modeling DEFINITIONS Keywords 4D BIM; Construction workspace management; Safety planning management; Building Information Modeling - BIM: is a platform, a technology, a process, in which a lot of technologies and software are combined This process aims to create, utilize and manage information including geometric and non-geometric information of construction projects With the simulation environment of BIM, the stakeholders can visualize the implementation process of a project and identify problems that may occur during the design, construction and operation phases It supports to provide timely resolutions and enhances the discussion between the stakeholders Safety INTRODUCTION The construction industry has a high rate of occupational accidents Therefore, safety is one of the issues that need to be considered when implementing a construction project Ensuring occupational safety is a guarantee for employees to have a safe working environment in which the risk of any possible safety hazards is minimized In order to ensure occupational safety on the construction site, the safety plan should be organized well at the planning phase.[1] Workspace: the required spaces to perform activities safely LITERATURE REVIEW Many technological innovations have been applied in the construction industry to make effective safety plans However, safety issues have not been much improved BIM can be utilized to improve safety by connecting the safety plan with the construction Table summarizes previous researches on construction management while workspace computation – simulation and workspace classification are presented in Table and Table 3, respectively © 2020 Association for Computing Machinery ACM

978-1-4503-8778-1/20/06…$15.00 There have been many studies on construction workspace management and there are many ways to classify workspaces In this study, the author defined three types of spaces as follows: https://doi.org/10.1145/3404649.3406879 - Worker space: the space required for workers, engineers to perform work safely, productively - Building component space: the space of the structural element itself, each building component takes up physical space on the construction site 72 - Machinery space: the space occupied by the machinery Some popular types of machinery on the construction site such as excavator, dumper, pump… worker, machinery) has its own space along with operation space and safety space These workspaces will be calculated by the safety engineer based on the construction method, the construction site status… The workspace of activity defined by this study is shown in formula (1) Each object in the model (building component, Table Summary of Researches

design coordination on the BIM model, the testing process can detect design conflicts Design conflict is a conflict among building components On the construction site, many activities can be performed at the same time to accelerate the schedule If different activities share the same workspace, a workspace conflict will occur There have been many studies carried out and identified many types of workspace conflicts In this study, the author focused on four types of conflict: - Safety hazard: conflicts lead to the risk of occupational safety loss - Congestion: conflicts occur when multiple teams of workers or machinery share the same space at the same time For example, many machines are in-and-out the construction site at the same time can lead to space congestion - Design conflict: construction projects become more and more complex, which requires many participants to join from the design phase These design participants will independently design their 73 - Damage conflict: conflicts occur when the workspace of the machinery collides with the space of a component that was completed Construction schedule in MS Project file This conflict results in damage to machinery as well as leads to occupational accidents Export MS Project file to XML format Workspace conflict can lead to delays in work performance reducing labor productivity and causing accidents that affect workers' health Therefore, workspaces and possible workspaces conflicts must be determined in order to take action to limit and eliminate these conflicts as soon as possible from the planning phase Export MS Project file to MS Excel file Link schedule from MS Excel to Dynamo Assign schedule from Dynamo to objects in Revit Import XML file to Synchro Pro This study aimed to support safety engineers to make effective safety plans so the authors only focus on researching conflicts leading to the risk of safety hazards and conflicts leading to damage Export Revit file to Synchro Pro METHODOLOGY Assign 3D objects to the activities by Auto matching feature 4.1 Integrate Schedule Information into the BIM Model 4D BIM model in Synchro Pro Figure The process to link schedule data to BIM model The 3D BIM model was built from the design phase without schedule information These data were set up on MS Project software which would be integrated into each model object by Dynamo and Synchro Pro 4.3 Identify and Resolve Workspace Conflicts After a 4D BIM model containing construction objects and workspace for each object was built, the engineers would run a 4D simulation to automatically check the workspace conflict Dynamo created variables containing construction schedule information (WBS) for objects in the 3D BIM model Objects in the 3D BIM model did not contain schedule information fields but Autodesk Revit allowed users to assign additional data variables to the object via Shared Parameter After the objects in the 3D BIM model were assigned schedule variables, schedule data from the MS Project file would be linked to these variables 3D BIM model of the project has hundreds of construction objects, it is impossible to manually assign schedule data to these objects An automatic solution selected in this case was to use Dynamo BIM to automatically assign data to objects After that, the 3D BIM model was exported from Autodesk Revit to Synchro Pro and schedule data was also exported from MS Project to Synchro Pro Finally, the Auto matching feature in Synchro Pro was used to assign 3D objects to the construction activities and to create a 4D BIM model Figure illustrates the process to link schedule data to the BIM model In case workspace conflicts are detected, safety planners can resolve workspace conflicts in the following suggested ways: - Option 1: Change the workspace by changing the size of the workspace - Option 2: Adjust the construction schedule by changing the start time, the end time or the duration of the activity When resolving the workspace conflict by changing the construction schedule, priority will be given to critical activities, only to adjust the schedule of non-critical activities as it will not affect the completion time of the project - Option 3: Combine the two ways, change workspaces while adjusting the construction schedule of activities to resolve workspace conflicts - Option 4: Make the safety plan to inform the workers about the location and time that the conflict may occur, equip safety measures to minimize the consequences when conflict happening 4.2 Create Workspace for Objects in the BIM Model The workspace would be simulated as a bounding box covering outside the object The dimensions of the bounding box would be calculated by the safety engineers The workspace in the BIM model is considered as temporary objects, which appear when the activity starts and disappear when the activity finishes, which means the workspace objects are also shown commensurately with the schedule of the corresponding construction objects Workspace objects were also assigned schedule information using Dynamo and Synchro Pro similar to construction objects The process of applying BIM to manage construction workspace is shown in Fig Start Schedule Schedule MS Excel Integrate schedule into BIM model Automatically identify WBS codes Create the 4D BIM model Revit Dynamo Revit Synchro Pro Dynamo Identify workspace conflicts Synchro Pro Yes Create workspace Dynamo Revit Resolve workspace conflicts No End Figure The process of applying Building Information Modeling (BIM) to manage construction workspace 74 CASE STUDY The results of the study were applied to the basement construction activities by bottom up method including Larsen sheet pile erection, Kingpost system erection, excavation, shoring system erection The first step was to assign schedule information to construction objects in the 3D BIM model, to simulate workspace objects in the 3D BIM model and to assign the corresponding schedule to these objects Figures and illustrate this process Then, the 3D BIM model from Autodesk Revit and schedule data from MS Project were exported to Synchro Pro to run a 4D simulation and check workspace conflicts The 4D BIM model is shown in Fig Figure Scripts to create workspace for Shoring system erection activity Figure Scripts to integrate schedule to objects in BIM Figure User interface to declare the workspace for shoring system erection activity Figure User interface to assign schedule to objects Figure The 4D BIM model in Synchro Pro Figure The workspace of Shoring system erection activity 75 Figure 12 The testing result The workspace is known as a space to ensure the activities can be carried out safely Therefore, depending on the construction method, the construction site status… the safety engineers can calculate the parameters of the appropriate workspace In the process of simulating workspaces for construction objects, the author created a User Interface for safety engineers - safety planners, who not need to understand the BIM platform, can easily declare the properties of workspace objects to automatically create these objects in the BIM model The process to create workspaces for Shoring system erection activities is illustrated in figures 6,7, and 8, respectively Figure Adjust the space conflict test mode Do the same steps to create the workspace for the Larsen sheet pile erection, Kingpost system erection, and excavation After building the BIM 4D model, Synchro Pro's Spatial Coordination feature can be used to check workspace conflicts The steps to check workspace conflicts and the testing results are shown in figures 9, 10, 11, and 12, respectively Based on these testing results, safety engineers can select timely solutions to reduces the consequences caused by these risks CONCLUSION Figure 10 The testing result The study has developed a process of applying Building Information Modeling BIM to simulate and detect workspace conflict supporting safety management The first step of the process was to build a 4D BIM model including schedule and workspace of the construction activities Then, the 4D BIM model was used to identify workspace conflicts among activities, thereby offering safety solutions to handle and reduce workspace conflicts The risk of conflict can be minimized which reduces the consequences caused by these risks ACKNOWLEDGMENTS This research is funded by Ho Chi Minh City University of Technology –VNU-HCM, under grant number T-KTXD-2019-80 REFERENCES Figure 11 The testing
