3D Community Visualization

Explore your project in a fully interactive 3D environment. This beta feature allows PMs and clients to visualize construction progress, identify zones, and navigate the site layout with architectural precision.

No phase starts without evidence.

Our dependency engine hard-gates every phase template across all trades. No subphase can begin unless its predecessors are PMC-approved. No verbal override. No workaround.

Site proof from the crew, not the office.

Tamper-proof, GPS-pinned, cryptographically signed photo evidence — reviewed in minutes, not days.

01

Native camera only

Gallery uploads are hard-blocked. Every photo must come from the device camera at capture time — eliminating backdated or substituted evidence.

02

Cryptographic integrity

GPS coordinates, UTC timestamp, uploader identity, and a SHA-256 hash are embedded the moment the shutter fires. Nothing is editable after capture.

03

Pre · During · Post slots

Every subphase requires three mandatory photo slots. PMC Engineers review all three before a single tap approves or blocks the next phase.

04

Offline-first sync

When site signal drops, photos queue on-device with full metadata intact. The moment connection returns, everything syncs in chronological order automatically.

Five steps from chaos to controlled execution.

Step 1

Everything starts with structure.

Create your project, add blocks, and BuildUNIX auto-loads your phase template with pre-configured dependency logic. No setup headache. No missed phases.

Stop the churn of money mismanagement.

Six capabilities that enforce accountability where Indian construction projects actually lose time, quality, and margin.

Dependency Engine

Pre-configured with a phase template for Indian residential construction — fully customizable to match your project structure. Hard gates, not suggestions.

Tamper-Proof Docs

Pre, During, and Post slots. Native camera only. Every photo embeds GPS, UTC timestamp, and a verifiable SHA-256 cryptographic hash.

Four-Type Snags

PMC, Safety, MEP, and Client QC snags. PMC snags block workflow. Safety and MEP snags block final phase completion. Full resolution threads.

Live Heatmap

A color-coded grid updates within 2 seconds of every action. Drill from company to project, block, phase, and subphase without losing context.

Automated Daily Reports

Structured PDF narratives generated at 9 PM with a chronological timeline, photo gallery, snag summary, progress metrics, and flagged items.

Offline Field Mode

Photos and metadata queue securely on-device, then sync in chronological order after reconnect. Supports high-volume offline capture in live site conditions.

Role-Based Visibility

Distinct roles for PMC Engineers, Contractors, PMs, and Clients — ensuring each stakeholder gets exactly the view and permissions their job requires.

shipping faster.

Shipped in six days. Six. Our existing platform took eight months and we still weren't live. BuildUNIX works because it bends to our workflow.
