[How teams build their apps](https://www.pelles.ai/pelles-build) 02 Agents Always on ## A bulletin lands overnight. The shop hears before it cuts. A VDC agent compares every new bulletin with the packages you’ve released. By morning the shop knows what to hold, and the RFI is drafted for your sign-off. (Illustration: At 12:40 AM the GC emails Bulletin 4 to the VDC agent. It compares the reissued sheets with the released prefab packages, checks the shop schedule, tells the shop lead in Teams to hold one rack, and drafts an RFI in Autodesk Construction Cloud. In the morning it messages the VDC manager in Teams and texts them, and sends the RFI once they reply yes.)

How does Pelles help VDC and prefab teams? It turns your start-up process, spec matrices and shop schedule into apps your VDC team, shop and field share. Agents compare every new bulletin and GC schedule with what’s already released, so changes reach the shop before it cuts. Does Pelles read our models? Pelles reads the documents around the model: drawings, specs, bulletins, RFIs and the GC’s schedule, from ACC, Procore and your file stores. Your models stay in the tools your VDC team uses today. Can it answer spec questions for prefab? Yes. Ask about any requirement, materials, hangers or seismic bracing, and get the answer with the section cited. A spec matrix app keeps the answers for every service and size, and updates them on each new set. Do we need developers to build these apps? No. Your team describes the process in plain words, and Pelles Build turns your framework document or spreadsheet into an app connected to your systems. Is our project data secure? Pelles is SOC 2 Type II attested, encrypts your data at rest (AES-256) and in transit (TLS 1.2+), keeps every customer’s data isolated, and never trains on your content.
