Project Assist AI — AI Agents for Civil Engineering Design

Leading Innovation. Empowering Engineers. Accelerating Infrastructure Design.

Project Assist began in 2019 as the first AI-driven road network design tool for Civil Site Design, helping engineers automate the creation of connected road models, intersections, curb returns, cul-de-sacs, and related design elements. That original technology has now evolved into Quick Start, a practical productivity workflow that helps designers move from initial layout to a working civil design model faster and with greater consistency.

Building on that foundation, Project Assist AI represents the next stage of Civil Survey Applications’ innovation. It combines decades of civil design automation experience with modern AI agents that can understand project data, review design conditions, explain workflows, generate reports, and recommend next actions — while keeping the engineer fully in control of the design process.

Civil projects should be delivered with speed and accuracy as a standard, but traditional workflows often come with a high overhead between separate design and drafting tools or the technical burden of managing over engineered three d models. Civil 3D, in combination with Civil Site Design, creates a powerful high performance design and drafting engine in a familiar CAD based environment. And now we're accelerating that process with Project Assist AI, Civil Site Design's built in AI assistant. It doesn't replace your expertise, it amplifies it. Project Assist AI handles the heavy processing for road networks and grading, helping Civil 3D users explore and refine designs faster while keeping engineering decisions firmly in your control. Rigid workflows are replaced by dynamic workflows. No more exporting. No more manual rebuilds. Just stable, responsive design that stays inside Civil 3D. And you get Civil Site Design's already powerful toolkit. Model Viewer, a real time design analysis tool, allowing you to identify grading conflicts and surface errors as you work. The vertical grading editor synchronizes profiles, cross sections, and the three d model with a single interactive interface. Automated subgrade layering, generating accurate pavement volumes and 3D subsurfaces directly from your design logic. Dynamic intersections that automatically recalculate when levels or alignments are shifted. And drainage and stormwater allows you to pass surface data for hydraulic analysis and pull pipe requirements back into your Civil 3D design and so much more. Trusted by teams across Australia and the world working in Civil three d every day. Civil 3D with Civil Site Design. Design, analyze, visualize, deliver.

Why Civil Engineering Requires More Than Generic AI

Generic AI tools and chatbots are useful for general information, but civil engineering design requires project-aware intelligence. Engineers need AI tools that understand CAD data, design standards, project requirements, and civil design workflows.

Most generic AI tools:

Lack civil engineering design context
Do not understand project-specific CAD data
Cannot validate design intent against standards
Cannot reliably review alignments, profiles, roads, intersections, or surfaces
Produce answers that may not be traceable to project requirements

Introducing TEX – the First AI Agent for Project Assist AI

The Saver Principal

TEX has been developed with the following guidlines:

S — Suggest – Provide recommendations.
A — Assess -Analyze project conditions.
V — Verify -Validate against standards and project requirements.
E — Execute -Perform approved actions.
R — Review – Provide documentation and traceability.

These principals ensure that designers are always in control of the design.

Project-Aware Intelligence

TEX inspects your drawing and will answer questions and create reports:

Alignment geometry – do they meet specs?
Roads – do they comply with local standards?
Intersections – are curb returns in compliance?
Report on horizontal alignments.
Create summary reports for volumes, structures and more

Need a report? TEX creates the report and saves it for future use

Understanding the Difference Between Chatbots and Agents

AI technology is changing rapidly. ChatGPT, Gemini, Claude all have their place; all are being updated regularly. As a project manager and designer, it is important that you do not get bogged down in the details. It is equally important that you understand the basic concepts.
