4D Sequencing & Logistics

Project Management (4D BIM)

Visualizing the Construction Sequence

Our project management workflow integrates scheduling timelines directly with the 3D model database (a process called 4D BIM). By matching Gantt chart tasks with specific model elements, we simulate the entire assembly sequence virtually. This allows planners to locate staging conflicts, optimize material storage coordinates, and preview the site's critical path before breaking ground.

During field operations, we run photogrammetric drone scans weekly. The resulting 3D meshes are overlaid onto the master model to automatically highlight execution deviations, track actual progress ratios, and verify milestones against the schedule.

Our Execution Methodology

01

4D Schedule Compilation

Consolidating Microsoft Project and Primavera P6 schedules and linking WBS activity keys directly with structural elements in the model database.

02

Sequencing & Logistics Sizing

Simulating temporary safety structures, crane sweep spheres, and material staging laydowns to identify physical space constraints.

03

Drone Mesh Overlay Checks

Conducting weekly drone photogrammetry flights to capture 3D point cloud coordinates matching exact current site geometry conditions.

04

Automated Milestone Audits

Overlaying point clouds onto 4D sequences to calculate precise volume completion metrics and automatically flag delays to stakeholders.

"Using Synchro 4D for the Nexus Plaza construction phase, TwinAnalytic optimized laydown zones, resolved 8 major crane-swing boundary conflicts, and delivered structural works 21 days ahead of schedule."

Core Workflows & Deliverables

  • 4D Sequence Animations: Visual simulations showing the day-by-day structural assembly plan.
  • Schedule Constraint Mapping: Syncing Primavera P6 or MS Project timelines directly with model meshes.
  • Drone Photogrammetry Audits: Mapping physical construction progress against model databases using point clouds.
  • Logistics Space Sizing: Simulating site access, crane locations, and storage layouts.
