JOS worked with Jackson Civil Engineering to deliver this scheme as part of the Perry Barr & Witton Flood Risk Management Scheme. We constructed the FRC works for the new structure whilst working adjacent to a temporariy diverted River Tame 
We delivered the works safely and on time to the delight of our Client which built on our excellent relationship with Jackson Civil Engineering 
A significant improvement we made to the outline methodology was to cast the headwalls in full height sections. This removed the need for a secondary upper level pour which would have required additional work at height and a longer programme. We also worked on the inlet & outlet structure similtaneously rather than linearly to better the programme. 
Our team of specialist joiners worked closely with our formwork supplier at Huennebeck to guarentee the quality product for the splayed headwall was delivered to the plan.
