Summary

DBS were appointed by Durham County Council (DCC) to support them on their Consett Business Park project.

DCC are developing a new build business centre on a brownfield site, the site was formerly used for mining and three capped mine shafts are present on site, along with associated Made Ground associated with colliery spoil. The Made Ground principally comprises mudstone.

Lime4 are providing project management support to DCC on the project and the principal contractor is Sir Robert McAlpines. The business centre will provide a range of new office units, together with communal areas, external landscaping and car parking. The site was subject to original characterisation in 2008 and since then it has remained in a cleared state awaiting redevelopment.

DBS were employed by DCC to check the current status of the site with regards to potential contaminants and risks to human health ahead of redevelopment work commencing.

DBS undertook an intrusive investigation of the formation layer using a grid system and obtained near surface samples for subsequent laboratory analysis from hand dug pits.  Samples were also taken from overburden stockpiles located on site to determine if they were suitable for re-use for landscaping areas within the scheme.

The samples were submitted to the analytical laboratory using full QA procedures.  Upon receipt of the results a Generic Quantitative Risk Assessment (GQRA) for human health was undertaken to identify if there were any risks to redevelopment workers, construction workers and future end users of the siteas a result of the sites former use.

The resultant report confirmed that the site could be developed safely, the business centre will be entering the construction phase in late 2012/early 2013 and will provide a sustainable centre for business bringing brownfield land back into beneficial use.

The new buildings will be incorporating renewable energies and are on course for a BREEAM excellent rating.
