WHAT WE DO

4D & 5D BIM -
Construction Planning & Cost Control

A well-structured information model is an extremely useful resource for all members of the project team. By linking scheduling data to different components, you can generate accurate program information and enable step-by-step visuals of your project's development. This process is known as 4D BIM. BIM is a collaborative way of working that engages the whole project team in the production of information, including Cost Managers. 5D BIM refers to the linking of cost data into information models to offer cost planning advice or generate estimates.

We create precise construction simulation and phasing videos by integrating project management tools like Primavera with BIM tools such as Autodesk Revit and Navisworks.

4D BIM - Construction Simulation & Scheduling

Our 4D BIM services integrate 3D geometric models with the project's construction schedule (time). By adding the fourth dimension to BIM, we enable project managers, contractors, and stakeholders to visualize the entire construction process step-by-step before breaking ground. This virtual construction approach identifies scheduling conflicts, improves site logistics, and ensures a safer, more efficient execution on site.

Construction Sequences

All standard sequences supported - from ground works and structural erection through to site logistics and final fit-out simulations.

5D BIM - Quantity Take-Off & Cost Estimation

5D BIM introduces the element of cost to the intelligent 3D model. By extracting highly accurate material quantities directly from the model geometry, we eliminate manual calculation errors. This allows cost consultants and estimators to generate precise Bill of Quantities (BOQ), track budget changes in real-time as the design evolves, and plan procurement with confidence.

Frequently Asked Questions

What schedule formats can you work with?
We can work with standard formats like Primavera P6 .XML, MS Project .MPP, Excel schedules, or we can build the construction schedule from scratch based on project parameters.
How accurate is BIM quantity take-off?
Highly accurate. BIM QTO extracts exact volumes, areas, and counts directly from the modeled geometry. The key is ensuring the 3D model is built with the correct LOD and structure for estimating.
Can you produce a cash flow from the model?
Yes, by combining the 4D time schedule with the 5D cost data, we can output projected cash flow across the project timeline, helping clients visualize expenditure over time.
What software do you use?
Primarily Navisworks and Revit for extraction and sequencing. We can also utilize specialized tools like Synchro 4D or dedicated 5D estimating software based on client requirements.
Team capabilities and proof of past projects?
We have dedicated planners, cost estimators, and advanced Navisworks operators on our team. We have successfully delivered 4D/5D solutions for large commercial and infrastructure projects. Contact us for sample outputs and case studies.
