Project Description

Client: LXB Retail Properties PLC
Location: Biggleswade, Bedfordshire
Year Completed: 2016
Project Value: £25m
Contractor: Ellmer Construction
Architect: Ratcliffe Grove Partnership

An extensive project to redevelop the existing Biggleswade Retail Park into a cohesive 330,000 sq. ft. retail park with parking and improved London Road access to the A1.

The project was completed in two phases over a period of 3 years. Retail tenants include M&S, Next, Matalan, TK Maxx, H&M, Laura Ashley, Halfords, Bensons, Boots, River Island and Wilko.

The Challenges

Gyoury Self undertook structural and civil engineering designs for the park’s thirteen, two storey, steel-framed retail units, below ground drainage systems, hard standings, access roads and car parks.

Foundation construction was complicated by a high water table and low bearing pressures at the upper level. To reduce the risk in the ground, Vibro Replacement was employed to improve the ground and allow the use of shallow foundations.

With the high water table and low infiltration rates, the use of traditional soakaways was not possible. The solution was for the surface water to be attenuated through a combination of porous paving, ponds and attenuation crates, together with the existing soakaways from the original development – prior to discharge of the excess water off site, to a ditch on the other side of the A1!

A 5m high free-standing acoustic wall was stabilised using cantilevered steel framing, supported by large reinforced pad bases.
