Project Overview
Semper Services executed a comprehensive gas riser replacement project for a major residential housing estate. The project involved the removal and safe disposal of condemned risers and the installation of new vertical risers and lateral distribution pipework serving multiple dwellings. This critical infrastructure upgrade ensures long-term safety and compliance for residents.
Scope of Works
Safe removal and disposal of obsolete gas risers
Installation of new vertical gas risers (multi-storey)
Lateral distribution pipework to individual dwellings
Relocation of domestic gas meters
Boxing-in and fabric works to internal resident properties
Installation of MOB (Meter Outlet Box) replacements
Comprehensive tightness testing and purging
Final commissioning and certification
Solution / Delivery
To manage the complexity of occupied buildings, we implemented:
Systematic scaffold tower erection for external access
Phased removal and replacement to minimize disruption
Draw-wire installation for new pipework routing
Rigorous strength testing and purge procedures
Coordinated meter relocations with residents
Outcome
The project delivered upgraded, fully compliant gas infrastructure with new vertical and lateral distribution systems serving multiple dwellings. All meters were successfully relocated and reconnected, ensuring enhanced safety and reliability. The works were completed with full certification, resolving legacy issues and securing the gas supply for the future.
