▬ I am a BIM Developer & Coordinator engineer with 5 years of experience : •As a BIM coordinator I coordinate the process of generating and managing digital models of buildings in order to model any building with LOD up to 700 using: -Revit to cover all modeling activities for all trades to produce design drawings and BIM shop drawings. -Navisworks to detect clashes, coordinate between different discipline and produce a 4D&5D model with the assistance of Primavera which help to create schedules for the projects and add the cost of everything (direct and indirect cost). •As a developer I make dynamo scripts, python codes, macros and add-ins using C# and Revit API which increase the speed of the BIM workflow and make it easier, also I use IFC to convert the model between different application either for coordination or model extraction. •Also as a developer I develop and make desktop applications that increase the workflow and make it easier not only for the BIM industry but also for all the engineering and administrative work also I can develop the interface of a program using XAML to create a WPF or using windows form, also I use VBA Excel to develop macros which decrease the time consumption. ▬ I make structural shop drawings using different programs or tools as (ArmaCAD, AutoRebar, ASD).
