Case study

Horizon 29, Buttermilk Lane, Bolsover, Derbyshire, East Midlands – Industrial Warehouse

Mayer Brown were appointed by St Francis Group, who are experts in Brownfield regeneration projects, to deliver the detailed design for extensive Section 278 highway works required to facilitate access to the development.

In a joint venture between St Francis Group and iSec, the 120-acre site, once owned by Coalite was reclaimed based on a multi-unit industrial warehouse scheme offering more than 1.4m sq. ft across 7 buildings.

Located off junction 29a of the M1 and adjoining the successful Markham Vale development, planning consent was secured across all phases, requiring substantial highway works valuing upwards of £7,000,000.

Details

The works briefly comprised of:

  • Improvements to the existing Markham Vale roundabout, increasing its capacity to deal with the additional traffic generated by the development
  • Improvements to 1.3 kilometres of Buttermilk Lane to create a consistent carriageway width and pedestrian route
  • Installation of two new roundabouts (one 3-arm and one 4-arm) and two new priority access junctions to serve the development plots.

Additional complexities to be considered during the design were:

  • A substantial reduction in height of a section of Buttermilk Lane to remove an over-bridge spanning a redundant railway line.  The design solution provided earthwork slopes to / from Buttermilk Lane and the redundant railway cutting to enable access to a potential future cycle route
  • Removal of an existing culvert over the River Doe Lea, requiring replacement with a new, wider concrete box culvert to support the improved and widened Buttermilk Lane.

How we overcame these challenges

Given the history of flooding of the River Doe Lea, it was critical that in advance of detailed highway design commencing, Mayer Brown’s drainage experts carried out extensive Flood Risk Analysis.  Via liaison with the Environment Agency and with assistance from our Topographical Surveyors, an accurate model of the existing river was produced, and worst-case future scenarios were modelled.  This enabled the heights of both Buttermilk Lane and the development site to be designed such that the risk of future flooding is minimised as much as possible.

During the life cycle of the project, Mayer Brown also provided cut and fill calculations for the development plots, helping to set the levels of the car parks and development units; liaised with Yorkshire Water to agree the design of foul water rising mains and pump stations; arranged the removal and relocation of Environment Agency flood monitoring equipment adjacent to the River Doe Lea culvert and provided Road Safety Audits before and after construction of the works.
