Specialist Signal Installation & Commissioning

While DST Contracting Ltd undertakes all civil engineering and infrastructure works, the installation, cabling, configuration, and commissioning of traffic signal equipment are subcontracted to approved and accredited traffic signal specialists. This guarantees that every system is installed to the highest technical standards and fully compliant with operational and regulatory requirements.

We also offer design review and regulatory support, assessing scheme drawings to ensure correct ducting, visibility, safety zones, signal positioning, and overall infrastructure compliance helping deliver efficient, safe, and fully functional signal installations.
