openBIM for AEC understanding

Within the AEC industry, standards are necessary to ensure that all project stakeholders are speaking the same language, thereby improving collaboration.  We can also process data to automate various processes if the data is standardised.

BIM (Building Information Modelling) is used to improve collaboration on infrastructure projects.  BIM is essentially ISO 19650, and it has various levels.

Building Models contain 3D information that shows how assets fit together.  Each of these assets may contain properties that can be used to look for clash detections.  Think of a CAD diagram, it lays out the plans for a building so all parties can see the proposed plan.  As CAD technology advances, you can add more information about the project.  For example, as an electrician, I only want to see the layers that affect my work.  CAD can be further extrapolated to show products and material information.

closedBIM: These were the original big BIM systems, including AutoCAD, Revit, and Bentley ProjectWise.  These tools feature visual editors and viewers, allowing them to securely store the files needed for a project and ensure that the appropriate people have access.  These all have their own proprietary standards.

openBIM: Read other parties' data, improves collaboration and consensus.  Easier to switch tools to reduce costs or get better features.  Consists of:

  1. IFC (common language)
  2. bSDD (industry common language)
  3. IDS (Requirement specification)
  4. BCF (check)
  5. openCDE (sharing with APIS)

Industry Foundation Classes (IFC) serve as the basis for standardising how information is handled.  Has standards for location, such as geographic information.  Materials, Geometry, and Spatial Structures are covered by IFC classes.  In each industry, these base IFCs are added to.  The BuildingSmart bSDD is an extension of IFC for specialised industries and sectors, published to provide more specific, agreed-upon standards.  

Project Requirements: These can vary, but having an agreed-upon format, such as an Information Delivery Specification (IDS), is helpful. Although it is not necessary or widely used, it ensures that precise details are provided.  Therefore, collaboration allows all parties to clearly understand what is needed using IDS.

IDS uses bSDD, which is based on IFC, so that the requirement specifications are precisely laid out.

openCDE defines technical interfaces, .....

AI Vendor Management - Formiti

AI is going crazy, and you can build your own but generally you need to look at a supplier, so it's worth understand management of Vendors, you as the controller using their service are at risk of them not making their AI operations transparent.  It's a big business risk to my clients.  

GDPR is closely linked to AI, and if you use a service/vendor, the reputation and fine risk may fall on you as the provider.  Need visibility into each vendor, how they are using AI, in turn they are using vendors so it's a nice complex dependency problem.  You need to be aware of what you are relying on.

Ensure contracts with vendors consider AI, how the process your data and how their sub process vendors do the same.

Track website customer behaviour, we use a vendor to clean up the data.  In turn, I have no idea that they are using AI outside of the UK or EU.  Follow the dependency chains as all this needs to be transparent to the end customer if needed.

Copilot Studio 2025 Notes

Copilot Studio is amazing, the licensing is complex, the AI integration is excellent. Architects really need to understand Licensing and billing or AI will get out of control.  The Purview and governance looks very good.  Copilot Studio Cost Estimator (preview June 2025)

MS Build 2025: 

MCP Server in Preview - possible to collect data from other AI services or write back.

Connector Kit - So can add custom connectors to from Power Platform Connectors including Copilot Studio - sounds great.

Agent Flow - Added functionality added to Power Automate flows (Copilot Studio aware), deployed via solutions.

Note: M365 Agent Toolkit is looking interesting to allow agents to do tasks with Office add-ins done using VS Code.

Licensing

You need to be aware:

  • M365 agents - need all end users to have M365 copilot licences, retail $20/user.  Alternatively users can consume the agents using a PAYG model per message (it racks up quickly).  Can add these to MS Teams and it appears then the people with licences can ask the M365 agent and others see the results (some more testing and understanding is need here by me).
  • Copilot Studio - Makes need copilot studio AI Studio/maker licence $30/retail, users don't need any licence to use but you pay per msg and this can rack up nice and quickly so watch the usage.  Buy in bulk message credits can help reduce the cost.
  • Each prompt generates multiple messages, these are all billable (complex to calculate)
  • (If you use Copilot Studio and it calls Azure AI Foundry, also bills Tokens (also complex to estimate)
  • Copilot Studio is using AI Foundry connector, it is a Premium connector)

Playwright Post 6 - Automating Canvas App MFA login for Playwright unattended for Canvas apps

Overview:  Modern security makes automating logins requiring MFA rather difficult.  This post looks at possible approaches to automate the login.

Option 1. Turn off MFA—not really, but you can set a conditional rule in EntraId to not perform MFA. This is not an option in many enterprises.

Option 2. Time-based One-Time Password (TOTP)—Microsoft Authenticator makes this pretty difficult. At least I can't do it, as the APIS are relatively limited. This is kind of expected, as it's a security measure.

Option 3. Programmatically acquire an access token without browser automation, use MSAL with a client secret or certificate (for confidential clients). 

Option 4.  Use Playwright to record the login and intercept the access token once logged in.  Then you can store it and use it.  There are a few easy options to get the session:

4.1. Retrieve the access token from the response once logged in

4.2. Retrieve from your local storage:

  const token = await page.evaluate(() => {
    return window.localStorage.getItem('adal.idtoken') || window.sessionStorage.getItem('adal.idtoken');
  });
4.3. Retrieve the token using Playwrite at the command run level

Note: This adds the token to my repository. Don't save the token to your repository if you don't realise that the Access/Bearer token will expire depending on what your EntraId sets. The default is 1 hour.

Option 4.3.1. Like option 4.3, use the refresh token to silently generate a new Access token. You store the refresh token during the recorded login (by default, it lasts for 90 days) to generate a new access token when you need it.

Option 4.3.2.  Take it further back to generate the refresh token using the access code you get at the original login, renew the "refresh token", and generate a new access token to run your tests.

If you decide to store your access token, refresh token or code, don't store them in your code repo.  You know why if you got this far.

Thought: as a refresh token works for 90 days on a sliding scale, I've never used the option 4.3.2, as by storing the refresh token, all I need to do is to extend the refresh token by using it to get an access token and the refresh token has 90 days from that point. 

This is the plan I'm thinking of using:

Entra AAD Security Groups - Remember

Overview: I have lost count of the number of poor Active Directory and Azure Active Directories I have seen.  I don't think I've ever seen a good Active Directory actually.  Certainly nothing large over 5K users. 

I'm working with a multinational, and we need to improve the security.  Things are a little all over the place, oddly named and inconsistent, basically the normal for an 300k internal user enterprise with history and multiple aquations.

I identify a coupe of properties that will really create a nice hierarchy, issue is I'm using more than the allowed 5k Dynamic AAD Security Groups.  

Group Types to be aware of relating to Entra

1. Static AAD Security Groups

Got to add the users manually, or at least automate the process for anything but the smallest of Entra users.

Static AAD Security groups can be nested.

3. Dynamic AAD Security Groups

Up to 5,000 dynamic groups.

You can inherit Security groups or be inherited (no nesting).

3. Distribution AAD Groups

Used for email and calendars, not security.

4. O365 Groups/Teams Groups

They can inherit O365 groups or AAD Security groups.  They are managed within the org so not the best idea to place heavy security on manually managed teams. 

Resolution:

I have a full hierarchy of users within divisions and subdivisions.  By adding users statically via automation to there lowest level AAD Security Group.  Then I can add the child groups.  This gives me multiple groups that have more and more users in as we go up the hierarchy.  Additive groups with positive security gives me the best options.  

Future Wishes:

If only Entra supported more dynamic AAD Groups per tenant or allowed Dynamic groups to be nested in static AAD groups

Playwright Post 5 - Understanding how Playwright Works

Playwright as a tool consists of two main parts.

Part 1: Playwright Library: This is the automation of a browser using the Page Object Model (POM). It provides a uniform API to run against the 3 main browser engines, automating tasks like navigating, clicking, filling in form data, and validating content on a web page. Classes include APIRequest, APIResponse, and BrowserContext. The worker process runs the API calls sequentially. Unified library API calls are sent to the browser context, which runs unaware of the calling context.  

Top link runs in Node.js and makes API library calls, there is no timing between the Node.js (Controller) and the browser instance (running Chromium instance)

Part 2: Test Runner: This part runs the Playwright tests.
