Amazing! Howells supplies Patent Glazing as part of £38 million Foss Barrier upgrade
Information about Howells supplies Patent Glazing as part of £38 million Foss Barrier upgrade
In December 2015, the city of York was hit by severe flooding. The flood rose to the highest level of the Foss River. Water entered the Foss Barrier’s main control building and incapacitated it. Within three months, work had begun on a multi-million pound improvement project to modernize the Foss Barrier to provide better flood protection for homes and businesses.
The Environment Agency appointed JBA Bentley – an integrated design and construction contractor that combines national contractor JN Bentley with environmental technology specialist Jeremy Benn Associates – as the prime contractor and CH2M (now Jacobs) as the modernization planner.
The barrier opened in 1988 and the modernization was intended to replace the gate and its mechanical parts, as well as access and architectural features. The building permit was issued to replace the original structure.
The Foss Barrier Gate is raised and lowered on steel wire ropes wrapped on drums at either end of the glazed bridge that connects the two side towers. The size of the towers and the bridge was increased to accommodate new lifting equipment and to replace the access ladders with stairs.
JBA Bentley hired Howells, the patent glazing specialist, to supply and install new and replacement glazing for the extended bridge. The Birmingham-based company was a new supplier to the main contractor and was sourced from the market.
Self-supporting glazing bead
After Howells had overcome many difficult design problems, Howells manufactured patented roof and vertical glazing with its self-supporting muntin bars HG2 and HG3, which were single-glazed with special laminated glass. The bars have been coated with polyester powder for durability.
Howells also designed and manufactured four adjustable slats within the vertical glazing. These were a direct replacement for what was there before and were used for ventilation.
The patent glazing was attached to a new steel frame within the construction.
Sophisticated design and fit
“The biggest challenge was getting everything in line after installation and making sure we were working with an existing structure,” said Richard Timson, site manager at JBA Bentley.
“We also had to ensure that the bridge in its new operation would not have any deflection that would affect the glazing. This was a factor one wouldn’t really understand until it was put into service.
“Working with Howells has been a very positive experience. They did exactly what they said they did. And given the complexity of the structure and its location, health and safety were good. Overall, we’re very impressed, especially as JBA Bentley and Howells hadn’t worked together before. “
The lock gate improvement work was completed earlier this summer and is now an integral part of York’s flood control system, protecting more than 1,200 local homes and businesses. The pumping capacity was increased and mechanical and electrical (M&E) equipment was replaced. The new 28 foot high lock gate was lifted in January 2021 and marks an important milestone for the project.
