LONDON SOUTHEND AIRPORT

DCE were instructed by London Southend Airport to undertake an assessment of the existing hardstanding and sub-base material together with the underlying subgrade ground conditions along the taxiways with respect to geotechnical issues relevant to the hardstanding surface.

The investigation included an intrusive investigation to identify the thickness and condition of existing hardstanding, to confirm the geology beneath the site and in-situ and laboratory testing to assess the geotechnical conditions beneath the site.

This investigation forms part of a portfolio of works undertaken for London Southend Airport.

PRIORS HALL, CORBY

Corby has a long history of large-scale ironstone mining, typically using dragline methods. Once the ironstone had been won the resulting voids were backfilled in an uncontrolled manner.

At Priors Hall, Discovery CE was appointed by BELA, the contractor responsible for the earthworks at the site, to provide technical advice and quality control services regarding all aspects of the earthworks operation. This has included a review of the risks associated with inundation and creep settlement, review of the compaction specification and testing programme and review of the risks associated with the material variability. Works at the 240 Ha site are ongoing.

BLAKENEY WAY, CANNOCK

The investigation area comprised a former open cast quarry which was backfilled via unknown operations between 1984 and 1993.  DCE investigations across the site revealed Made Ground depths to between 86 and 90 m bgl.

DCE were appointed to design a ground improvement strategy for the development of an industrial unit on site with financial, time and special constraints.    Following assessment of the suitability of different ground improvement strategies DCE developed a successful unique ground improvement strategy which allowed delivery of the project within time and budget.  As a result of our successful ground improvement on site traditional pad foundations can be used for the proposed development which will be constructed late 2016.

VERIFICATION SERVICES – BARROW IN FURNESS

Discovery CE provide verification services for Ground Improvement works to confirm that the requirements of the ground treatment have been achieved.

Works such as those carried out at a 4Ha commercial redevelopment at the Waterfront in Barrow in Furness typically comprise an assessment of the available geotechnical data together with inspection of the treatment process.

Verification testing at the site comprised a suite of static cone penetrometer testing and “Zone Testing” using 2 m x 2 m square plates loaded to 120 kN/m2. The testing confirmed that the ground treatment process was successful in producing a development platform suitable for the proposed office development.
