Unlike a chatbot that only produces an answer, an agent can query documents, execute scripts, interact with engineering software, update records, or chain multiple tasks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This shift from \u201cresponding\u201d to \u201cacting\u201d radically changes risk assessment. An incorrect answer can be discarded by the user; an incorrect action can alter a model, generate a document, modify a configuration, or propagate an error to later stages. Therefore, agents applied to engineering require much stricter architecture, permissions, validation, observability, and governance than isolated use of generative AI.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The concept also needs to be distinguished from conventional automation. A deterministic workflow executes fixed rules. An agent uses a model to interpret the situation and choose among alternatives what to do next. This flexibility is precisely its advantage \u2014 and its main source of uncertainty.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In engineering, agents make the most sense when the process involves large volumes of information, multiple tools, and intermediate decisions that can be verified. Examples include repository queries, document triage, BIM automation, preparation of analyses, issue classification, record updates, and coordination of technical tasks.<\/p>\n\n\n\n\n<h2 class=\"wp-block-heading\">What distinguishes an AI agent from an assistant<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"\/conteudo\/artigos-tecnicos\/inteligencia-artificial-na-engenharia\/\">Artificial Intelligence in Engineering pillar<\/a> organizes agents as a more autonomous layer within the AI ecosystem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An assistant responds. An agent executes a cycle.<\/p>\n\n\n\n<figure class=\"a3a-mermaid\"><svg id=\"a3a-diagram-1\" width=\"100%\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"flowchart\"

engineering<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This structure can be simple or complex. In some cases, the agent only decides which query to execute. In others, it coordinates different tools and subagents.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Assistant<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Receives a prompt and responds.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Copilot<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Works inside an application and offers suggestions or automations.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Agent<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Plans and executes actions using tools.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Multi-agent system<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Multiple agents have different roles and exchange information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These terms are not perfectly standardized across suppliers, but the functional distinction helps define risk and controls.<\/p>\n\n\n\n\n<h2 class=\"wp-block-heading\">Components of an agentic architecture<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">An agent is not just a language model.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Model<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Interprets objectives, context, and results.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Memory<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Maintains information about previous steps, preferences, or workflow state.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Tools<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">APIs, scripts, databases, CAD\/BIM software, search systems, document systems, or other services.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Orchestration<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Controls sequence, rules, loops, limits, and stopping conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Identity<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Defines who or what the agent represents and which permissions it has.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Guardrails<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Restrict actions, data, tools, and responses.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Observability<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Records decisions, calls, errors, tokens, cost, and result.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Evaluation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Measures whether the task was completed correctly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Agent quality depends on the entire architecture, not only the model.<\/p>\n\n\n\n\n<h2 class=\"wp-block-heading\">Model Context Protocol and integration with engineering tools<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">During 2026, Bentley began providing MCP servers to connect agents to applications such as STAAD.Pro and MicroStation. The Model Context Protocol allows AI applications to discover and use tools in a standardized way.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This represents an important change: the agent can leave the chat environment and act directly on engineering software.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bentley describes cases in which agents query data, automate workflows, perform structural analysis, and manipulate CAD elements through natural language. At the same time, its guidelines emphasize that MCP access should be treated like granting access to a person or integration, with equivalent governance and approval.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This rule is essential: <strong>an agent with a write-capable tool should be treated as an identity with operational capability<\/strong>.<\/p>\n\n\n\n\n<h2 class=\"wp-block-heading\">Applications of AI agents in engineering<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Agents in BIM and CAD<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">BIM and CAD models are natural environments for agents because they contain objects, properties, commands, and APIs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An agent can:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>locate elements;<\/li><li>query properties;<\/li><li>generate scripts;<\/li><li>change parameters;<\/li><li>create objects;<\/li><li>perform checks;<\/li><li>prepare documentation;<\/li><li>classify issues.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Capability needs to be divided into levels.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Level<\/td><td>Action<\/td><td>Risk<\/td><\/tr><tr><td>read<\/td><td>query model<\/td><td>low\/moderate<\/td><\/tr><tr><td>analysis<\/td><td>calculate or compare<\/td><td>moderate<\/td><\/tr><tr><td>proposal<\/td><td>generate a change without applying it<\/td><td>moderate<\/td><\/tr><tr><td>write<\/td><td>modify model<\/td><td>high<\/td><\/tr><tr><td>execution<\/td><td>publish or send<\/td><td>high\/critical<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Autonomy should increase gradually.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In <a href=\"\/servicos\/planejamento\/projetos-em-bim\/\">BIM Design Services<\/a>, agents can accelerate operations;  <a href=\"\/servicos\/planejamento\/gestao-bim-informacao-engenharia\/\">BIM and Engineering Information Management<\/a> needs to maintain states, permissions, and requirements of the official model.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Agents for technical documentation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Documentation is one of the most accessible use cases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An agent can monitor a folder, identify a new document, extract metadata, classify it, compare revisions, and generate a record.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But automation of controlled documents requires caution.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The agent needs to distinguish draft, approved, superseded, and canceled documents. It also needs to respect permissions and naming rules.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"\/conteudo\/artigos-tecnicos\/rag-na-engenharia\/\">RAG in Engineering<\/a> can function as a knowledge layer for agents that need to query documents before executing tasks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Agents for Design Review<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">During technical review, an agent can gather documents, check a checklist, locate changes, and prepare a list of issues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It can also query requirements and suggest questions for review.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The agent should not issue technical acceptance on its own. The safest role is to prepare evidence and reduce reviewer effort.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the process has significant consequences, <a href=\"\/servicos\/planejamento\/revisao-validacao-tecnica-projetos-design-review\/\">Design Review<\/a> remains a human and independent barrier.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Agents for project management<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Projects generate schedules, open items, meeting minutes, RFIs, documents, and risks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Agents can:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>consolidate meetings;<\/li><li>update issues;<\/li><li>classify open items;<\/li><li>retrieve decisions;<\/li><li>compare versions;<\/li><li>generate alerts;<\/li><li>prepare status reports.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The advantage lies in the ability to cross-reference sources and execute tasks in sequence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Risk appears when the agent begins to change official information without supervision.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A model may suggest that an open item is closed; actual closure should depend on evidence and authority.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Agents for procurement and suppliers<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An agent can read proposals, extract data, compare requirements, and build a preliminary matrix.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It can also query specifications and identify gaps.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But commercial and technical proposals contain ambiguities, exceptions, and conditions that are not always captured automatically.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The output should be treated as preparation for bid leveling, not as a procurement decision.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Multi-agent systems<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In multi-agent systems, roles are distributed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One agent may research, another analyze, another review, and a fourth execute.<\/p>\n\n\n\n<figure class=\"a3a-mermaid\"><svg id=\"a3a-diagram-2\" width=\"100%\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"flowchart\" style=\"max-width:min(1540.5px,

complexity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Each communication between agents can introduce context loss or error.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is necessary to define which agent has authority for each action.<\/p>\n\n\n\n\n<h2 class=\"wp-block-heading\">Agent architecture, security, and control<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Deterministic orchestration vs. autonomous planning<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Not every agent needs to decide everything.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A hybrid architecture is usually safer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Predictable steps can be coded deterministically, leaving the model only tasks that truly require interpretation.<\/p>\n\n\n\n<p

perspective.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When not to use agents<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An agent should not be the default.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the workflow is stable and deterministic, conventional automation may be better.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If a task is critical and does not have rapid verification, autonomy may be inappropriate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If APIs, permissions, or logs do not exist, the integration may be fragile.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If data are not governed, the agent merely automates disorder.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Agent maturity model<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Level<\/td><td>Capability<\/td><td>Control<\/td><\/tr><tr><td>1<\/td><td>response and querying<\/td><td>review<\/td><\/tr><tr><td>2<\/td><td>read-only

class=\"wp-block-paragraph\">Most use cases do not need to reach level 6.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Task planning and autonomy limits<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The central element of an agent is transforming an objective into a sequence of actions. This planning capability needs to be constrained by the problem domain and available tools.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An agent for BIM coordination may receive the objective of preparing an issue list, but it should not automatically receive permission to modify the official model. The architecture should separate planning, proposing, and executing.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Mode<\/th><th>Capability<\/th><th>Control<\/th><\/tr><\/thead><tbody><tr><td>Assistive<\/td><td>suggests next steps<\/td><td>user executes<\/td><\/tr><tr><td>Supervised<\/td><td>prepares action<\/td><td>human confirmation<\/td><\/tr><tr><td>Restricted<\/td><td>executes permitted actions<\/td><td>policy engine and logs<\/td><\/tr><tr><td>Autonomous<\/td><td>decides and executes multiple steps<\/td><td>independent barriers and monitoring<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Identity, credentials, and segregation of duties<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Agents should not share generic credentials. Whenever possible, each agent or service should have its own identity, allowing actions to be attributed and permissions revoked without affecting other workflows.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Segregation also applies to functions. An agent that prepares an analysis should not necessarily be the same one that publishes the result. Separating preparation and approval creates a barrier similar to segregation used in human processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Credentials, tokens, and secrets should not appear in prompts or memory. They should be provided through secure execution mechanisms, with limited scope and validity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to prevent loops and error propagation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Agents can enter loops: query, conclude that information is missing, query again, and repeat without progress. They can also propagate errors when an incorrect intermediate output feeds the next stage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Practical controls include iteration limits, token budgets, timeouts, explicit stopping conditions, intermediate verification, and human checkpoints.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In long workflows, each critical stage should validate its received input. This prevents unjustified confidence from accumulating along the chain.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Agents in brownfield environments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Brownfield projects have legacy systems, incomplete documentation, and poorly standardized interfaces. Agents can help query and organize this environment, but integration needs to recognize that APIs, data, and permissions may be heterogeneous.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A prudent strategy begins with read access and assessment. Write actions are added only where reliable rollback and validation mechanisms exist.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This progression prevents the agent from becoming an opaque layer over systems that already have technical debt.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Operational metrics for agents<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to success rate, operations should track indicators that reveal behavior and cost.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>actions per task;<\/li><li>tools used;<\/li><li>human confirmation rate;<\/li><li>rejected actions;<\/li><li>interrupted loops;<\/li><li>permission errors;<\/li><li>average time;<\/li><li>cost per task;<\/li><li>incidents;<\/li><li>need for later correction.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These indicators help determine whether increasing autonomy truly reduces effort or merely shifts work to review and correction.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">From proof of concept to corporate workflow<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A demonstration may work with an experienced user, limited data, and a controlled environment. Production requires identity, availability, error handling, documentation, support, and change governance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before scaling, the organization should answer who owns the agent, who approves new tools, how incidents are handled, which versions are supported, and how the workflow is deactivated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Without these answers, the agent remains an experiment, even if technically sophisticated.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Technical checklist before granting a new tool to an agent<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Each new tool expands the agent&#8217;s action surface. Before enabling it, the team should verify whether access is truly necessary and what the consequence of misuse would be.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>which operation the tool allows;<\/li><li>whether access can be read-only;<\/li><li>which objects or projects become visible;<\/li><li>whether a sandbox environment exists;<\/li><li>how authentication and secrets are provided;<\/li><li>which actions require confirmation;<\/li><li>how the result is recorded;<\/li><li>whether the action can be reversed;<\/li><li>what the call limit is;<\/li><li>who can revoke permission.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This analysis turns the tool into a governed resource rather than an implicit agent capability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Agent versioning and regression testing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An agent is composed of model, prompt, tools, policies, memory, and integrations. Changing any of these layers can change behavior.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, relevant versions need to be identified and associated with a test set. When a model is updated, the agent should repeat known tasks and failure cases to verify that the change did not introduce regression.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The same applies to an API or tool update. A schema change can cause incorrect calls even if the model has not changed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Agents as part of the quality system<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Agents can be used not only to produce, but also to verify. A review agent can check whether another agent attached evidence, used authorized sources, or followed a sequence of steps.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This approach does not eliminate human review, but creates additional barriers and makes the workflow observable. In higher-criticality processes, independent controls should exist outside the execution agent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most mature architecture combines deterministic rules, automated validations, and human approval, reserving model autonomy for decisions that truly require interpretation.<\/p>\n\n\n\n\n<h2 class=\"wp-block-heading\">Final considerations<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">AI agents represent one of the most significant changes at the interface between artificial intelligence and engineering because they connect models to real tools.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This capability transforms productivity and also risk.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A mature architecture requires <strong>bounded objective \u2192 minimum tools \u2192 permissions \u2192 guardrails \u2192 testing \u2192 approval \u2192 observability \u2192 improvement<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The more an agent can act, the less governance can depend on the agent itself. Critical controls need to exist outside the model, with identities, policies, logs, and human authority.<\/p>\n\n\n\n<div class=\"wp-block-a3a-destaque\">\n<p class=\"wp-block-paragraph\">When agents from different suppliers access models, documents, and systems, the owner needs to preserve requirements, segregation, and acceptance independently of the platform.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"\/servicos\/contratacao-integrada\/engenharia-do-proprietario\/\">Owner&#8217;s Engineering<\/a><\/p>\n<\/div>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Technical references<\/summary>\n<p class=\"wp-block-paragraph\">[1] BENTLEY SYSTEMS.
