Delivering Safer, Smarter, Lower‑Cost Project Outcomes

Overview

Roading Industry Support Services Ltd (RISS) has proven that technology‑enabled TTM oversight can transform project delivery.
By integrating continuous monitoring, automated alerts, and NZGTTM‑aligned reporting, RISS delivers safer, smarter, and more cost‑efficient outcomes for contractors and clients

This case study highlights the performance of RISS’s integrated monitoring and oversight system on a 25‑week programme, showing how continuous monitoring and NZGTTM‑aligned processes deliver measurable value for contractors and clients.

Challenge

Traditional TTM delivery relies heavily on onsite labour and manual observation. In the Waikato, short‑term TTM operations average $3,695 + GST per day, creating cost pressure and inconsistent oversight.

Key issues:

• High daily costs for extended programmes
• Limited visibility outside staffed hours
• Mobilisation delays and re‑establishment costs
• Increased risk exposure during unobserved periods

Contractors needed a safer, more efficient, and more consistent way to manage TTM risk.

Solution

RISS deployed its technology‑enabled TTM oversight model, integrating:

• Continuous remote monitoring of TTM layouts
• Automated alerts for deviations and risk triggers
• Evidence capture for TMP compliance
• Oversight of portable traffic signals and site behaviour
• NZGTTM‑aligned reporting and operational assurance

This system operates 24/7, eliminating mobilisation delays and ensuring uninterrupted visibility.

Results

Cost Efficiency

• Traditional TTM: 175 days × $3,695 = $646,625 + GST
• RISS Model: 175 days × $1,372 = $239,100 + GST
• Total Saving: $406,525 + GST (63 % reduction)
