Pricing Analysis
Average project pricing is rising gradually because tunnel operators are specifying more integrated control, safety, and analytics features. Retrofit projects often carry higher integration and commissioning costs than standard new-build packages. Software and service content is also increasing the average system value per tunnel.
| Cost Component | Share (%) |
|---|---|
| Precision electronics and control hardware | 34% |
| System engineering and software development | 22% |
| Installation and commissioning labor | 18% |
| Testing, certification, and compliance | 12% |
| Sales, project management, and after-sales service | 14% |
Typical gross margins are in the 18%–28% range for integrated systems, with software and service contracts often achieving higher margins than hardware-only projects. Large public tenders can compress margins, while customized retrofit packages usually improve profitability.
