Survey & terrain
Connect site boundaries, survey control, terrain models and existing levels.
B3 Nexus · Site Intelligence
Start engineering from an evidence-rich model of the real site.
Nexus Site & Context Intelligence is designed to bring together survey, terrain, existing infrastructure, utilities, hydrology, geotechnical information, access, logistics and environmental constraints before major engineering decisions are locked in.
Quick answer
What should site intelligence change?
The value is not a prettier map. Better site intelligence should influence earthworks, foundations, drainage, roads, site logistics, construction sequencing, infrastructure placement and environmental protection.
- Survey and terrain
- Existing infrastructure and utilities
- Hydrology and environmental constraints
- Geotechnical and earth-observation evidence
- Access, logistics and planning context
Big Three innovation model
The site is the first engineering model.
Every infrastructure project begins with physical context. When terrain, utilities, drainage paths, ground conditions, existing structures and access constraints are considered separately, coordination risk enters the project early. Nexus creates a unified site representation.
The objective is to connect geospatial and engineering information so that design and construction choices are tested against the actual conditions of the site rather than isolated drawings or assumptions.
Connected capabilities
How this fits into the Big Three delivery model.
Each capability strengthens engineering decisions, construction execution, evidence and lifecycle value across the project lifecycle.
Utilities & infrastructure
Represent roads, services, structures and existing infrastructure that affect design and sequencing.
Water & hydrology
Use catchments, drainage paths and water constraints to inform platforms, roads and stormwater strategy.
Ground conditions
Bring available geotechnical information into earthworks, foundation and ground-engineering decisions.
Environmental context
Represent land use, climate, environmental constraints and sensitive areas within the engineering context.
Access & logistics
Understand haul routes, site access, laydown, crane zones, temporary works and construction movement.

Frequently asked questions
Practical answers about how Big Three Engineering connects digital engineering with physical delivery.
What information can site intelligence combine?
The site-intelligence model combines boundaries, survey, terrain, utilities, roads, land use, environmental constraints, hydrology, geotechnical information, earth observation, planning, access and existing structures.
How does this affect civil engineering?
It can inform earthworks strategy, drainage, road alignment, foundation strategy, infrastructure placement and construction sequencing.
How does site intelligence support survey and geotechnical teams?
It gives survey, geotechnical and engineering teams a shared evidence base connecting terrain, control, ground conditions, utilities, hydrology and project constraints.
How do drone and LiDAR data strengthen the site model?
Drone survey, LiDAR and photogrammetry add high-resolution terrain and reality data to site understanding, design coordination and later verification.
