Godstow weir situated in a very picturesque spot in the river Thames, just north of Oxford. On this site there was an existing set of six manually operated sluice gates approx. 1500mm square. The existing gates were not used as they had failed due to their age.

The existing weir was to be completely removed and replaced. The existing weir was situated directly downstream of a medieval bridge (Godstow Bridge) which complicated matters as we were not allowed to fix to the bridge in any way during the construction works.

The site is situated directly next to the Trout Inn which was part of the reason aesthetics of the finished structure were so important to the client.

The new weir system was similar to the old in that it was made up of six new gates of similar size. These were lead screw driven gates powered by electric actuators. The gates were fabricated in line with Execution class 3 in accordance with BS EN 1090. The gates were fabricated from S355 J2 grade carbon steel whilst the frames were fabricated from 316 grade stainless steel plate. All steel painted with industrial coating system.

Various access bridges were built to gain access to the structure as the main concrete section of the weir was moved further downstream of the bridge.

Accoya timber was used to produce the decorative handrail all around the site including on the access and operations bridge sections.

The site included a 1.2m wide by 11m long fish pass situated on the South side of the site.
