Our blue-chip client required an upgrade to their existing dated heating system, that was not coping with demand, was prone to failures, was inefficient and required considerable reactive maintenance ongoing. Maintenance access was further complicated by the heavily congested space. Metropolitan were selected to carry out the works following successful completion of a similar project for the same client at a different site. They required a technical engineering company who could and manage the design process, installation, and handover of the heating system whilst the building remained occupied and operational throughout.
Metropolitan secured the site and implemented all necessary CDM requirements including temporary COVID-19 welfare facilities, to facilitate segregation for our installing operatives for the duration of the works. A temporary heating solution was implemented, prior to de-commissioning the existing system. The existing plant was dismantled and removed from site for recycling. New plant layout designs were completed to incorporate the new boilers, pipework, dosing pot, Air & Dirt Separator, Pressurisation Unit, Low Loss Header and Gas Solenoid Valve amongst others. The new layout provided unrestricted access for future maintenance. Civil works were conducted to remove the existing pump plinths. The existing flue dilution system was removed and replaced with a compliant system. All penetrations were fire stopped throughout. New pipework was chemically cleaned and dosed with inhibitor, with new thermal insulation and aluminium cladding applied. The obsolete controls were replaced with new, head end graphics updated, and all systems fully tested, commissioned, and balanced. Full client demonstration and FM training was delivered upon completion, with comprehensive ‘As Fitted’ Drawings and O&M Manuals supplied at handover.
