01 Features

From excavation to report, site data in one app.

Records entered on site move through reporting and approval within the same app.

Works tracking

Record critical works such as forepoling (umbrella arch), soil nails, steel ribs and shotcrete by chainage.

Daily reporting

Create daily reports with excavation and support data as PDFs instantly.

Approval mechanism

Manage approvals within the app through an approval hierarchy built for the Contractor, Consultant and Client roles.

Visual archive

Document each stage of the works with photos and follow face advance visually.

02 Roles and approval flow

3 roles, one approval hierarchy.

The approval flow is built around the relationship between contractor, consultant and client on tunnel projects.

Step 1

Contractor

Records site works by chainage, documents them with photos and submits them for approval.

Step 2

Consultant

Checks the records submitted by the contractor and evaluates them at its own approval step.

Step 3

Client

As the final link in the approval hierarchy, reviews the records and daily reports.

03 Who it is for

For teams working on tunnel sites.

The app was developed drawing on the 15 years of site experience of our founder, who served as head of technical office on İSKİ's 9.4 km TBM and NATM wastewater tunnel and on the Ordu Ring Road Terzili tunnels.

Tunnel engineers

Record works data on site and monitor excavation and support progress by chainage.

Site managers

Prepare daily reports from the site and manage the approval of works through the app.

Supervision teams

Review photo-documented works records and access technical reports wherever you are.
