Your site, on autopilot.

47 subs to chase, 6 sites to walk, the structural questions nobody else can answer. Vonbuild runs the chase on autopilot and gives you instant Eurocode verification when the as-built deviates from the drawing — sign off on site, don't call the architect.

Today vs tomorrow

Chasing today. Deciding tomorrow.

Today

You ARE the project's nervous system.

7am — walk Zone A. 9am — phone the electrical sub. 10am — answer the architect's RFI on the slab. 11am — sign three NCRs. Noon — chase the mason for daily report. 2pm — emergency: as-built deviation on column C-247, can't pour until it's verified. Architect's not picking up. You wait two days. Concrete delayed two days. Margin gone.
By Friday: 12 hours of WhatsApp, 0 hours on the actual decision work.
With Vonbuild

The chase runs itself. The decisions are yours.

The agent chases the laggard subs across Teams and WhatsApp. Reads the daily reports the moment they land. When the as-built deviates on C-247, you ask the agent to verify against EN 1992 §6.4 — answer in your hand before the architect calls back. Concrete pours on schedule.
By Friday: site is yours. Phone is quiet.
The cross-functional superpower

The as-built deviation. Verified before the architect calls back.

A structural deviation on site is two problems at once. Operations needs to know if you can pour. Engineering needs to know if it's still compliant. Vonbuild gives you both — in minutes.
01
Master Operations

Reads the field. Catches the deviation.

The foreman photographs the as-built on column C-247. Operations ingests the photo + measurements via your site report app. Identifies a 4cm deviation from the structural drawing. Triggers the verification chain. Trigger: 2pm. Pour scheduled: 4pm.
02
Master Engineering

Runs the punching shear. Returns the verdict.

Operations hands the deviation to Engineering. Engineering re-runs the EN 1992 §6.4 punching shear check with the as-built parameters. Outputs vEd, vRd,c, utilization. Verdict: still OK at 0.81 utilization. Result: 2:23pm. Architect not needed. Concrete pours at 4pm as planned.
Result · 23 minutes across 2 Masters
vs. 2 days waiting on architect

Site decision in your hand. Architect signs off after the pour.

As-built captured + structural verified + verdict in writing — full audit trail backing your call. The concrete pours on time. 2 days of programme protected. €18K of standby costs avoided. Architect signs the formal RFI response next morning, on the back of the work you already did.
Live process · Operations cascade

You query Operations. Five agents react. One status report.

A scheduled progress check fires. Master Operations spawns five site-monitoring agents in parallel. Schedule, snags, subs, slip — all reconciled into a single weekly status. Subcontractor follow-up auto-queued.

Signal

Weekly progress check fires at 14:32.

Any source can fire it: a file dropped in OneDrive / Google Drive / any drive, an email landing in Outlook, a scheduled task firing, or you pressing a button. In this scenario, an event arrives via SCHEDULE.

Source: SCHEDULE · weekly-progress-check.task
Routing

MASTER OPERATIONS routes.

It classifies the impact across 21 semantic categories and dispatches to the 5 specialized agents concerned. No human in the loop. No meeting scheduled.

5 specialized agents dispatched · 312 ms
Parallel reaction

5 specialized agents. In parallel.

Each agent accesses its own toolset — apps, browsers, MCP connectors, project documents and company knowledge — and produces a structured output. Concurrently, not sequentially.

Outputs return. One narrative.

The 5 specialized agents return their outputs to MASTER OPERATIONS. It reconciles them into a single decision card.

Validation

Handed to you. One click.

Master Operations delivers the weekly status. Schedule remapped, subcontractors chased, progress verified, defects logged, critical-path slip quantified. Full evidence chain. One trace ID. Status ready to circulate.

Self-scheduled trigger

T+3 DAYS LATER. The system wakes itself up.

During the parallel phase, a agent scheduled a follow-up task on its own. T+3 DAYS LATER — without you, without a meeting, without a reminder email — MASTER OPERATIONS wakes itself, dispatches the right agent, and executes autonomously. You delegated the mental load.

When the client audits the as-built, you have receipts.

Site decisions stick to your signature. Four guarantees that hold up at handover.
Guarantee 1 · Certified verification

Eurocode check, not AI guess.

Engineering verifications run through Computer Use on certified software (Robot, ETABS) or auto-coded normative scripts validated against reference cases. Real number. Real clause cited.
Guarantee 2 · Site-report evidence chain

Photos, measurements, timestamps.

Every deviation captured with the photo, the measurement, the timestamp, the foreman ID. Hashed and logged. Pulled back instantly years later when the DLP claim arrives.
Guarantee 3 · You sign off

Agent flags. You decide.

The workforce surfaces the verification. You make the call on whether to pour. Your sign-off stays in the audit log. The agent never authorises irreversible site actions.
Guarantee 4 · Site WiFi tolerant

Runs even when the trailer router doesn't.

Processing runs server-side. Site teams upload when they have signal, results sync when they're back. Nothing depends on the basement signal at Zone B3.
Live demo · Guarantee 3 in motion

This is what "you decide to pour" looks like.

The as-built verification is on screen. The verdict is OK. Then the modal blocks. Your click authorises the pour. The AI prepares; your sign-off stays in the audit log for the DLP claim that may arrive in year 7.
Works where you work

Procore, Plangrid, Teams, WhatsApp. Same tools.

No app to install on the foreman's phone. The agent reads the daily reports, posts to your existing Teams thread, chases subs on the channels they already use.

How to justify Vonbuild to your boss.

You're the site manager. Your PD reviews monthly margin. Three bullets that move you from "good site manager" to "indispensable".
Bullet 1 · Standby avoidance
€10K+/day
cost of a stopped pour

"Concrete pours on schedule. Always."

When the architect can't be reached and the as-built deviates, the pour stops. €10K–€20K of crew + crane standby per day, every day. With on-demand structural verification: decisions made on site, pours on schedule.
Bullet 2 · Sub-chase overhead
12 hrs/wk
recovered from chasing

"Half my week was WhatsApp. It's now site walks."

Sub-chasing typically consumes 10–15 hours per site manager per week. With autopilot: laggards messaged on schedule, exceptions escalated to you. Hours redirected to actual site supervision and decision work.
Bullet 3 · Snag closure
2 wk → 2 days
handover preparation

"Handover packs that don't kill the weekend."

5,000-document as-built handover, snag tracking through DLP — historically a 2-week marathon for the site team. With the workforce: assembled in 2 days. Site manager closes out one project to start the next on time.
Numbers are industry benchmarks (Part3 2025, AACE 29R-03 surveys). Calibrated to your projects in the demo.

Start with the site you can't keep up with.

The project where you're constantly behind on RFIs, sub chases, and structural questions. The handover that's slipping into your weekends. That's where it earns it.
