box culverts

Posted by & filed under Construction.

When a housing development in Lincoln was set to create 374 homes, a question was presented as to what drainage solution to use. BPDA member Forterra came to the rescue by supplying around 600 precast box culverts to the development.

Forterra, who worked together with the main contractor, Daniel Charles Construction, designed the drainage system to take surface water run-off from the development. The water is run through channels to control chambers. It is then stored into three large storage tanks, and discharged to a drainage ditch alongside the A46. Almost 2 million litres of surface water can be held in the drainage system, making it the ideal solution.

Measuring 2 metres long by 1.2 metres wide, and weighing around eight tonnes, it was expected that the delivery and installation of the box culverts would be tricky. Partner this with the difficult to access site, and you might expect to run into some problems. However, Forterra’s expertise meant that delivery and installation went very smoothly, forming runs of around 90 metres in length.

The box culverts were installed in 2 stages to ensure efficient and correct installation. The project for Forterra lasted 18 months, resulting in a well performing complete drainage system that the Construction Manager, Tony Higgins, and end client, Taylor Lindsey Homes, were very happy with.
