Form of Contract
JCT 16

CDP awarded CORE a £6.5 million deal to carry out earthworks and infrastructure at a major new business park located at Junction 1 of the M621 and Junction 27 of the M62 near Leeds.

The 70 acre site has planning permission for 1 million sq.ft of commercial development.

Scope of works:

To remove an estimated 550,000 cubic metres of material from a large plateau that has been previously constructed. The material had to be stored around the perimeter of the site, to be placed back into the excavated area in engineered layers.

CORE’s infrastructure contract included 1000m of drainage & sewerage in addition to 450m of road, new services, attenuation pond, fencing and new pumping station.

The earthworks contract included substantial excavation and filling of up to 550,000m3 of material, large scale earthworks, dynamic compaction of a 45,000m2 area plus grouting of 25,000m2 and the creation of a new access road and stone platforms measuring 36,000m3.


There were many complex challenges to the project, including removal and processing of  100,000m3 of rock, excavation and transportation of the remaining material to temporary storage areas, sequencing of the earthworks to coordinate with dynamic compaction and the replacement of the material into the compacted excavated area in engineered layers. The use of our motor-scrapers represented the quickest and most cost effective method for moving large amounts of material around the site. The project was completed on time and within budget.
