    Brief

    Trinity House is seeking a contractor to replace HVAC systems at their Harwich site, which includes two buildings: a main office (3 floors) and buoy yard (2 floors). The existing Daikin systems have been operational since 2006 and consist of floor-wide arrangements with roof-mounted fan coil units and independent room-based units. The project requires supply and installation of replacement equipment on a like-for-like basis to maintain the original building performance for heating and cooling across both buildings, excluding two IT server rooms. The contractor must coordinate all works to minimize disruption to the active office environment, manage full installation, configure the centrally-controlled systems via portal, conduct acceptance testing, and provide comprehensive training on both local and remote supervisory platforms. This is a turnkey project combining procurement, installation, system integration, and staff training.
