Project Description

Following on from the site clearance works at the end of 2020 the bulk enabling works on SEGRO Logistics Park Northampton (SLPN) commenced in March 2021. The bulk earthworks consisted of circa 4.1 million cubic meters being excavated from maximum depths of 15 meters and placed as engineered fill to plateaus for distribution units as well as landscape bunds surrounding the project with as much as 18 meters of engineered fill being placed behind mechanically stabilised earth walls.

Along with the major development of SLPN, Collins was involved in the delivery of upgrading J15 of the M1. This involved the earthworks and capping to slips roads, gyratory system and widening of the A45 & A508.

In the second year of the development, works commenced on the construction of Roade Bypass which has been in the pipeline since 1988. The new 2.5km carriageway will start at the north of Northampton Road A508 and run to the west of Roade village tying into the A508 to the south at Stratford Road.

During peak weeks earthworks outputs achieved up to 120,000 m3 of engineered fill each week.
