Project description

Development of a large shed for Manchester based, online fashion giant Boohoo who are expanding their existing distribution warehouse in Burnley. At 63,000 sq ft the new warehouse and office development represents a significant increase in capacity over their existing facility.

Ground conditions

The former agricultural area has been developed into a sizeable industrial park in recent years. The site consisted of varying depths of made ground overlying clays of variable strengths.


To bring settlements within an acceptable level a vibro stone column solution was proposed as an economical alternative to precast piles. A small amount of upfill was carried out across the building footprint prior to installation of the VSC’s. To accomodate high-bay racking a bearing pressure of 60kN/m2 was required beneath the substantial floor slab area. Treatment beneath the floor slab was monitored closely by site and operations to ensure that settlements fell within the required tolerance.
