Maintaining positive long-term relationships

Development on the former site of RAF West Malling at Kings Hill, near Tonbridge, began in 1989 and has continued more or less ever since. We’ve been involved in projects at Kings Hill for circa 25 years; a great testament to the quality of our work and commercial relationships.

In 2018, following a competitive tender process, Gallagher Ltd won the contract for new infrastructure to serve further future housing development. The scope included enabling works to remove an existing road and stockpile management ahead of new road construction.

We built two new roads, each around 650m, with associated drainage and services, plus street lighting as a contractor-designed element for the cabling layout. These link existing roads at one end of the site and a roundabout at the other. The work involved collaborative planning with numerous utility providers to remove existing networks and switch them over to the new link roads and associated future plot connection.

All hard material arising from the works, including rock from excavations, was crushed and re-used as granular fill; by using the existing stockpiles, we didn’t need to import any sub-base or drainage backfill material. Where we removed existing roads, all excavated material was used as fill to form a future parkland area, so no material was removed offsite.

We also constructed a propeller from gabion walls filled with Kentish Ragstone from our Hermitage Quarry, to commemorate the area’s former life as a RAF airfield.
