How teams build their apps

02AgentsAlways 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.

In their words

  • “Pelles.ai has led us to rethink our workflows by identifying problems and ambiguities earlier and reducing risk across our operations. It's the only AI platform built specifically for subcontractors, created by a team with the experience and insight to truly understand what matters to our industry.”

    Joel SchrinerPE, Principal Engineer, Peck Hannaford + Briggs

  • “AI made custom software practical for our business. Pelles made it achievable. They quickly understood our vision, transformed it into tools built around our workflows, and have remained a true partner throughout the journey.”

What teams ask before they start.

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. People see the projects and documents they can already open.
