Teddington Lock, London
In the Summer issue of ’fluid’ last year we introduced the challenge at Teddington Lock; a complex,
high-profile structure at the tidal limit of the River Thames. That early-stage investigation has now
moved firmly into delivery.
Towards the end of 2025, the head and tail mitre gates from the Launch Lock
were removed and transported to Centregreat Ltd for shot blasting, detailed
inspection, and refurbishment. All works are being carried out in line with
KGAL’s design specifications, translating last year’s recommendations into
physical upgrades.
Attention has now turned to the installation phase. The existing head gate
quoins have been removed, making way for new KGAL-designed stainless steel
pintles and quoins. These are currently being installed and we were recently on
site supporting BAM Nuttall to ensure correct alignment with the existing sill
and surrounding structure.
On site, progress has seen the Launch Lock fully dewatered and 3D scanned,
allowing us to carry out precise dimensional verification. Datum levels, alignment,
and positioning of key components are now being checked against design intent a critical step where everything needs to be measured and confirmed.
Work is also beginning on the removal of the tail gate quoins, continuing the
sequence of upgrades across the lock.
