Client Overview

A private construction company with 200+ field and office staff was relying on a legacy .NET-based application to manage project inspections, contractor documentation, and internal approvals. The system was no longer mobile-accessible, difficult to update, and heavily reliant on manual paperwork and nightly data syncs with back-office systems.

The company needed a secure, modern platform that would work seamlessly across job sites, support remote data capture, automate approval processes, and scale with their growing operations.

HarjTech was engaged to replace the legacy system with a robust, cloud-based solution built on Microsoft Power Apps and Azure Logic Apps.

Key Challenges

• Field staff relied on paper forms and spreadsheets for inspections and reports
• Approvals were delayed due to email chains and manual routing
• The .NET platform lacked flexibility and mobile support
• Nightly data syncs often failed, creating downstream issues in reporting
• High dependency on IT staff for minor updates or form changes
