4D Scheduling

Reduce your construction time by up to 10% using BIM. 4D schedules streamline your project by spotting out of sequence work and improving the efficiency of your job site.

Our 4D scheduling overlays your schedule onto the 3D model, turning it into time-lapse simulation. Out-of-sequence work and site-access issues jump out instantly, so you can resolve them in the boardroom, not on site. 

By visualising every hand-off and overlap, 4D simulations expose hidden float and compress critical paths. Crews stay productive, idle gaps disappear, and milestones move forward, often by days or even weeks. You deliver earlier without adding resources or taking on extra risk.

When the timeline drives the model, surprises vanish. Resolving sequencing issues before ground is broken slashes change orders, reduces material waste, and minimizes costly rework. The result is a smoother site, safer work environment, and a healthier bottom line.

4D scheduling adds the  dimension of time to your 3D model.

Each element in the 3D model is linked to an activity in your schedule, creating a  simulation of the build sequence. As the timeline plays, the model builds itself, showing crews, equipment, and temporary works appearing and completing exactly when planned.

• Data-Driven Links – Tasks pull durations, crews and predecessors straight from your schedule, so the simulation is in sync with the latest schedule.

• True Sequencing Visibility – You can see how foundations pour before steel rises, or how façade panels follow behind scaffold moves, no more black-box Gantt charts.

• Scenario Sandboxing – Copy the model, tweak phasing or start dates, and instantly watch the impact on milestones and resource peaks.

• Clear Communication for All – Planners, supers, and trade partners share a single, visual source of truth. Confusion drops, accountability climbs.

4D scheduling turns a static schedule into a living movie of your project, revealing conflicts, unlocking efficiencies, and aligning the entire team before the first shovel hits the ground.

By tying every schedule activity to your 3D model, the 4D schedule plays the build in real time, exposing sequencing clashes, phasing issues, and safety issues during the preconstruction process.

4D simulations play a large role in helping to streamline your project and keep things running smoothly.

Spot Conflicts Before They Cost You

Linking time to the model reveals hidden sequencing clashes, trade-stacking, and site-access issues, making them obvious red flags that can be addressed in pre-construction, not during expensive overtime.

Compress the Critical Path

Test alternative phasing, shift start dates, or add crews with a few clicks. Watch the schedule tighten in real time and pull milestones forward without adding risk.

Show, Don’t Tell, Stakeholders

A 60-second time-lapse replaces pages of Gantt charts. Owners, supers, and trade partners instantly “get” the plan, approvals come faster, and questions disappear.

Lock In Safety & Logistics

Overlay cranes, lay-down zones, exclusion areas, and pedestrian paths on the timeline. You create a living safety map that de-risks the site and proves due diligence.

Protect Your Bottom Line

Fewer change orders, less rework, and a smoother hand-off between trades translate into lower costs and healthier profit margins, often paying for the simulation many times over.

1 Kick-off call (30 min) – We agree on milestones, flag high-risk zones, and pick your preferred engine—Navisworks Timeliner or CMBuilder. Decide whether you’re sending us an existing 3D model or adding 4D to the Pixel BIM modelling or full BIM package.

2 Send Us Your Schedule (+ model) – You send us your schedule in your preferred format or CSV file.
  • Standalone: attach your Revit models.
  • Add-on or part of a BIM package: we create the model first, then pull your schedule.

3 Link tasks to the model – Every activity is mapped to its matching element. You’ll receive a first-pass time-lapse within two weeks, fast feedback without the wait.

4 Run “what-if” simulations – We can test alternative phasing, crew sizes, and logistics in Navisworks or CMBuilder to expose trade sequencing, access issues, and hidden float. You choose the leanest path.

5 Review & deliverables – You will receive an MP4 video file and shareable .NWD or CMBuilder link.

Send us your files today and see your project build itself – sequenced, optimized, and presentation-ready by next week.
