Platforms

For companies we assemble the tools into complete solutions: one project database, roles, approvals, reports. Five platforms are already clickable demos: Geo, Site Control, Metrology, Survey and the rebar shop. Demo data is fictional and stays in your browser. The rest are built with pilot customers.

ISKRIT·GeoDemo

A LIMS for the geotechnical laboratory: from borehole to report

  • Boreholes, samples and test assignments in one journal
  • Calculation modules: GOST 20522 statistics, soil mechanics, grading, logs and sections
  • DXF and XLSX export, AGS4 import
Open the demo →
ISKRIT·Site ControlDemo

A working board for construction supervision: issues and approvals

  • Issues and punch lists on a kanban board with history
  • Contractor, supervision and client roles, one-click approvals

Platforms are deployed around your process: a pilot on your data, module tuning, corporate invoicing.

Anonymous input

The tools only need numbers and tables. Drawings, estimates and project details stay with you and never reach the server.

A tool built around your process

We turn a repetitive spreadsheet calculation into a web tool: input validation, server-side calculation, printable output and export. Several calculations merge into one flow. A first prototype usually takes days, not months.

  • A spreadsheet calculation becomes a validated web form
  • Several calculations merge into one flow
  • We work from anonymous numbers: no drawings or project details
