Virtual Construction
Plan. Model. Build. Deliver.
Advanced CAD/CAM & Prefabrication Expertise
The John F. Gallagher Company has established full CAD/CAM capabilities within our fabrication shops. By producing in-house pre-fabricated assemblies, we deliver proven cost savings, accelerate on-site installation, and provide added value with superior quality results for our clients.
Leading the way through Virtual Construction
Through Virtual Construction, we build each project twice—first in a digital environment and then in the field. This approach allows our engineers to construct the building information model exactly as it will be built onsite, ensuring precision and efficiency. By doing so, we gain the ability to accurately estimate, coordinate seamlessly, schedule effectively, and deliver every project on time and within budget.


Benefits to our approach:
Complete coordination, fabrication, installation, and as-built drawings
Encourages pre-planning
Fewer trade coordination change orders
Improved maintenance functionality
Maximizes pre-fabricated assemblies
Shorter schedules
Lower construction costs
Optimizes trade installation sequence
Complete project visualization prior to actual construction
Reduces waste and redundant field layout and rework
The Value of Virtual Construction
By modeling projects before they are built, we identify conflicts, improve coordination among trades, and streamline the construction process. Virtual Construction gives our team the tools to deliver accurate estimates, predictable schedules, and reliable results in the field.
Improved Accuracy
3D modeling and BIM technology allow us to detect clashes, resolve issues, and ensure systems fit exactly as designed before construction begins.
Better Coordination
Virtual models provide a clear view for all project stakeholders, streamlining communication and aligning trades for smoother execution.
On-Time Delivery
By building the project digitally first, we reduce delays, anticipate challenges, and keep construction moving according to schedule.
