Construction

Sealed Evidence for Every Site, Trade, and Handover

Capture site work the moment it happens. Photos, videos, timestamps, location, and operator — sealed and tamper-proof. Defensible across the full Defects Liability Period.

The Challenge for Construction Teams

Without verifiable site evidence, defects, disputes, and DLP claims default to whoever has the cheapest excuse.

Hidden Works Close Up Before Sign-Off

Plumbing rough-ins, waterproofing, in-slab electrical — buried within 48 hours, disputed within four years. Phone photos in someone's camera roll don't survive a project.

Defect Disputes Years After Handover

Defects Liability Period claims arrive a year, three years, five years after practical completion. The supervisor has changed, the trade has dissolved, and the photos are on someone's old phone.

Scattered Photos and No Chain of Custody

Site evidence lives across phones, group chats, drives, and memory. None of it is retrievable in a defensible way when an insurer or principal asks for proof.

Slow, Costly Investigations

Once a dispute starts, the project manager's calendar gets wrecked. Hours go into reconstructing what happened — instead of running the next job.

How PackProof Protects Construction Projects

Turn every site action into verifiable, time-stamped evidence — defensible for the life of the project and beyond.

Capture at the Moment of Work

Site supervisors, foremen, and trades capture photos and videos directly in PackProof — sealed before the file leaves the device.

SHA-512 Sealed Records

Every photo and video is sealed with a unique SHA-512 digital fingerprint, time-stamped, and tied to the operator. Tamper-proof from capture.

Instant Retrieval Years Later

Search by project, area, trade, or date. Three years from now, sealed evidence comes back in seconds — not by digging through old phone galleries.

Defensible Across the DLP

Sealed records carry their own provenance: timestamp, operator, location. Defensible across the full Defects Liability Period — including civil and infrastructure projects with extended liability windows.

Simple Workflow for Site Teams

PackProof fits into your existing site routine — no new equipment, no new admin.

1

Capture

Site team opens PackProof on their phone. Photo or video against the project, area, or hold point.

2

Seal

Each file is sealed with SHA-512 at capture. Timestamp, operator ID, and (when location is enabled) GPS coordinates attached automatically.

3

File

Evidence is filed by project, area, and date — searchable for the life of the Defects Liability Period.

4

Verify

Generate a public verification link for the certifier, insurer, principal, or lawyer to verify directly. (Shareable verification links are an Enterprise feature.)
