4D Scheduling
At Reltic BIM, we turn traditional project planning into a powerful, interactive experience. With our 4D BIM modelling services, you’ll see more than just a building – you’ll visualise the entire construction process from start to finish.
By combining 3D BIM models with time-based scheduling data, we help you make smarter decisions, avoid costly mistakes, and deliver your projects more efficiently. Whether you’re managing a new build, refurbishment or complex extension, 4D BIM gives you the visibility and confidence you need at every stage.
Bringing Time into the Model
4D BIM stands for Building Information Modelling with time integration.
It’s the process of linking your 3D digital model with a detailed construction schedule to simulate how your build will evolve over time – day by day, task by task. It’s like watching your construction project unfold as a virtual movie that you can pause, comment on, and adjust before work even begins.
With 4D BIM, we give you more than visuals. We provide a tool for strategic thinking, allowing you to:
- Plan logistics, storage, and materials
- Allocate trades and workforce more effectively
- Reduce clashes and delays
- Understand the impact of every change - in real time
More Control. Less Risk. Better Outcomes.
Whether you’re a contractor, developer, or architect – 4D BIM puts time back in your hands and gives your team a shared vision to work from.
Traditional scheduling methods like Gantt charts only offer a limited view of your project. But with 4D BIM construction planning, you get a dynamic and detailed visualisation of your entire programme.
Here’s what 4D BIM delivers:
- Early detection of sequencing conflicts
- Optimised use of labour, equipment, and materials
- Improved site safety through better planning
- Clear communication for all stakeholders
- Faster and more predictable delivery
- Reduced risk of costly errors or rework

Not Just for Mega Projects
Many people assume that 4D BIM is only relevant for huge commercial developments or infrastructure projects. But at Reltic BIM, we know that 4D construction planning can benefit projects of all sizes - and we’ve proven it across a wide range of real-world applications.
From single-family homes to tight urban refurbishments, 4D BIM modelling brings measurable value by improving coordination, reducing risks, and giving you greater control over your project timeline.
4D BIM allows homeowners, self-builders and developers to visualise the build sequence, understand logistics, and avoid costly missteps. It’s perfect for scheduling tasks like groundwork, framing, MEP installation, and finishes with precision.
Luxury refurbishments often involve detailed finishes, specialist contractors, and tight schedules. 4D BIM gives you a step-by-step simulation of the process, helping avoid overlap between trades and ensuring seamless delivery.
These types of projects come with space restrictions, structural complexities, and safety considerations. With 4D construction planning, we map out each phase - from excavation and underpinning to fit-out - reducing disruption and keeping progress on track.
In larger developments, timing is everything. Our 4D BIM services synchronise construction across multiple units and phases - ensuring consistency, reducing bottlenecks, and improving site logistics.
For office fit-outs, hospitals or care facilities, 4D BIM modelling allows for detailed phasing and planning in sensitive environments. We help clients meet strict deadlines, reduce disruption, and plan effectively around live operations.
In busy cities or tight plots, space is a luxury. With digital construction sequencing, we help you plan everything from scaffold positioning to material storage and delivery access - improving safety and keeping the programme moving.
Plan With Precision. Deliver With Confidence.
If you’re managing tight programmes, overlapping trades or restricted access sites, then 4D BIM construction sequencing is your secret weapon for keeping everything on track.
With Reltic BIM, you get a clear, visual roadmap of your project – helping you deliver smarter, faster, and more safely.

Safer Sites. Smarter Planning. Better Outcomes.
A well-planned site isn’t just more efficient – it’s safer, cleaner, and far less stressful to manage. With 4D BIM, you can plan and visualise logistics and safety measures before construction begins, helping to eliminate guesswork and reduce risk across your site.
At Reltic BIM, we use 4D construction sequencing to support clear and practical logistics planning, giving site managers and contractors the tools they need to organise space, movements, and temporary works with precision.
Safe access and egress routes
Plan pedestrian walkways, emergency exits, and access points for operatives well in advance. Avoid last-minute re-routing and ensure full compliance with safety regulations from day one.
Crane and vehicle movements
Whether you’re lifting steel frames or coordinating city deliveries, 4D BIM schedules plant use, crane lifts, and vehicle access at the right time – avoiding clashes and congestion.
Scaffold stages and site zones
From initial scaffold erection to phased dismantling, you can simulate the entire scaffold lifecycle, making it easier to manage working platforms, edge protection, and trade access.
Temporary works and hoarding
Accurately plan the position of hoarding, fencing, site cabins, skips, and other temporary structures. Avoid obstructing key areas or limiting access to important work zones.
