Transcend has introduced Ask TDG and MCP Gateway, two enterprise AI capabilities for its Transcend Design Generator (TDG) platform, designed to help water, wastewater and power infrastructure teams access engineering knowledge and use structured design data across authorized AI environments. The release pairs a documentation-grounded assistant with governed access to selected engineering functions, while keeping engineering calculations within TDG’s deterministic, traceable design engine.
Transcend Adds Enterprise AI to Infrastructure Engineering Platform
Transcend has introduced two enterprise AI capabilities for its Transcend Design Generator (TDG) platform, targeting engineering workflows across water, wastewater and power infrastructure. Ask TDG provides an AI assistant grounded in the platform’s technical documentation, while MCP Gateway allows authorized AI environments to access selected TDG engineering capabilities and structured outputs.
The announcement reflects a broader effort to connect generative AI interfaces with established engineering systems without handing critical calculations to probabilistic language models. For utilities and engineering firms managing complex infrastructure projects, the distinction is important: AI can help users interpret methods, explore information and move data between systems, while the underlying engineering engine remains responsible for calculations.
Transcend describes TDG as a generative engineering platform built on deterministic, traceable, first-principles engineering logic. Its purpose is to bring preliminary design into earlier planning stages, helping asset owners evaluate options before budgets and project scopes are finalized.
Two AI capabilities serve different engineering tasks
Ask TDG brings a natural-language assistant directly into the TDG platform. Users can ask questions about the engineering methods, calculations and technology-selection approaches used by the software. According to Transcend, responses are grounded in its technical documentation, helping teams understand the reasoning behind design options.
The assistant does not perform engineering calculations, alter design results or replace expert review. That boundary separates documentation-based assistance from the engineering work itself, a relevant safeguard in infrastructure projects where incorrect assumptions can affect costs, specifications and long-term asset performance.
MCP Gateway addresses a different need: connecting TDG with external AI environments. It uses the Model Context Protocol (MCP), an open standard for connecting AI applications with external tools and data sources, to provide authorized access to selected TDG capabilities and structured outputs.
When an approved AI environment invokes an available capability, TDG performs the engineering operation. The resulting data can then support utility analytics, digital initiatives and downstream workflows, subject to the access and capabilities configured for that environment.
Together, the tools aim to make engineering knowledge and outputs easier to access without treating a general-purpose AI model as the authoritative source of technical calculations.
Deterministic design remains the engineering foundation
TDG is designed to generate preliminary engineering packages from project criteria such as flows, electrical loads, treatment objectives and site constraints. Transcend says the platform can produce designs for facilities including drinking water and wastewater treatment plants, electrical substations and pump stations in minutes.
The company says the platform integrates process, civil, mechanical, electrical and structural calculations in one engine. When a project assumption changes, the corresponding calculations across disciplines update together.
Generated design packages can include process diagrams, three-dimensional building information modeling (BIM), equipment lists, bills of quantities, operating expenditure estimates and a basis of design. These outputs give project teams a structured starting point for comparing alternatives and evaluating capital investment requirements.
The new AI capabilities operate around this engineering foundation rather than replacing it. Ask TDG helps users understand how TDG approaches a design problem; MCP Gateway makes selected engineering functions and their structured results available to authorized AI systems. The approach may help teams incorporate AI into existing workflows while retaining a traceable link to the underlying engineering process.
Shared standards and equipment specifications support consistency
Transcend is also positioning TDG Nexus, its existing ecosystem for sharing approved utility standards and technology specification packages, as part of the platform’s governed engineering foundation.
Utilities can share their own design standards packages with authorized teams through Nexus. Technology specifications from equipment providers, including Xylem and DuPont, can also be applied to designs. This creates a common reference point for utilities, engineering firms and technology suppliers evaluating alternatives during early planning.
Access to current, permissioned standards and equipment data can be particularly important when project teams need to compare options across locations or coordinate work between organizations. However, the quality of the resulting design process still depends on the accuracy and currency of the source information, the scope of the selected engineering capabilities and appropriate human review.
Infrastructure AI adoption moves toward controlled workflows
Transcend says TDG is active in more than 120 countries and has been used to generate more than 20,000 designs, with an impact on 652 million people. The company also identifies major water and power utilities, including Sabesp, Severn Trent, Scottish Water and Mekorot, among its users. It says five firms included in ENR’s 2026 Top 500 Design Firms use the platform, including WSP, STV and CHA.
These figures and customer examples are company-reported. They indicate the platform’s stated reach but do not independently establish the performance or cost benefits of the new AI features.
For infrastructure organizations, the release highlights a practical enterprise AI pattern: use language models to improve access to technical knowledge and orchestrate approved workflows, while keeping calculations in a specialized system with defined engineering logic. The model’s value depends not only on conversational capability but also on permissions, traceability, data quality and integration with existing operational processes.
The next test for this approach will be how effectively utilities and engineering teams incorporate the capabilities into real project workflows, including whether they can reduce friction in understanding designs and transferring structured data without compromising engineering oversight.
Market Landscape
Enterprise AI adoption in engineering is moving beyond standalone chatbots toward systems that connect models with specialized software, technical documentation and controlled data access. In critical infrastructure, this requires a clear division of responsibility between AI-assisted interaction and authoritative engineering computation.
Transcend’s release combines a documentation-grounded assistant with MCP-based access to selected engineering capabilities. The model is designed to improve how teams ask questions and use design outputs, while TDG remains responsible for performing the engineering calculations. Shared standards and equipment specifications add another layer of consistency across project stakeholders.
The wider market challenge is balancing faster workflows with reliability, auditability and human accountability. For utilities, AI-enabled engineering tools must fit into established design reviews and project governance rather than bypass them.
Top Insights
- Two distinct capabilities: Ask TDG answers questions grounded in technical documentation, while MCP Gateway connects authorized AI environments with selected TDG engineering functions and structured outputs.
- Calculations stay in TDG: Transcend says its deterministic engineering engine performs the calculations, keeping AI assistance separate from authoritative design computation.
- Earlier design evaluation: TDG generates preliminary design packages that can help utilities compare alternatives before finalizing budgets and project scopes.
- Governed data sharing: TDG Nexus supports sharing approved utility standards and equipment specifications across authorized project participants.
- Scale claims need context: Transcend reports more than 20,000 generated designs across over 120 countries, but these figures do not independently measure the impact of the newly announced AI features.
