Koh Kock Leong Enterprise

Digital permit-to-work system for construction safety and compliance

We partnered with Koh Kock Leong Enterprise to transform their clunky, paper-based permit-to-work processes into a modern digital system. By building a comprehensive mobile and web platform, we reduced permit submission and approval time from 30 minutes to just 3 minutes per permit—a 90% improvement. The system eliminated repetitive manual steps, provided real-time visibility for approval chains, and empowered the right people with the right information at the right time. Two months post-launch, user surveys showed significant improvements in satisfaction with PTW creation and management.

90% Time Reduction

Slashed permit submission and approval time from 30 minutes to just 3 minutes per permit, dramatically improving operational efficiency and reducing project delays.

Eliminated Paper Processes

Digitized the entire permit-to-work workflow, eliminating paper forms and manual handoffs. Staff and key personnel now save hours each week previously spent on paperwork.

Real-Time Visibility & Alerts

Approval chains gain instant insights into each permit's status through the dashboard. Push notifications ensure decision-makers are immediately alerted, preventing bottlenecks and ensuring rapid response.
