Navigators Walk, Nash Road

Taking on the role of Principal Contractor for a £19 million development requires absolute logistical control and a strict commitment to site safety. Our team takes full responsibility for planning, managing, and monitoring every phase of the enabling works, substructures, and infrastructure installation.

We understand that the success of any large-scale housing development relies entirely on the quality and efficiency of the initial groundworks. A project of this magnitude requires a highly organised operational hub to support the daily activities of a massive construction workforce. We set up all necessary site facilities, welfare units, and temporary infrastructure to ensure a safe, compliant, and highly efficient working environment from the very first day.

Site logistics play a critical role in keeping a development of this size on track. We manage strict traffic management protocols, designated delivery zones, and secure perimeter fencing. By establishing clear temporary access routes and secure compound areas, we ensure that the high volume of construction traffic flows safely without causing disruption to the surrounding local road network.

Extensive Earthworks and Site Clearance

The earthworks phase at Navigators Walk represents a monumental logistical operation. Before any structural work begins, we must prepare the raw land to exact specifications. Our team executed a thorough site clearance and vegetation strip, removing all overgrowth and unsuitable materials to reveal the workable ground beneath.

Following the site clearance, we manage large-scale cut and fill operations. We move and redistribute thousands of cubic metres of soil across the site to achieve the precise design levels required by the project architects. Executing an earthworks programme on this scale requires an extensive fleet of heavy excavators and articulated dump trucks working in perfect synchronisation. We meticulously manage site stockpiles to ensure maximum material reuse during the later landscaping phases, dramatically reducing waste and minimising the carbon footprint of the development.

Substructures, Foundations, and Specialist Piling Works

Creating a solid, immovable foundation forms the most critical element of any residential build. Because Navigators Walk encompasses 250 diverse plots—including heavy two-storey blocks of flats—the ground conditions require a multi-faceted approach to substructure engineering.

Our team holds responsibility for the precise construction of varied foundations across the site:

Trench Fill Foundations

For areas of the site with stable, load-bearing soil, we excavate and pour traditional trench fill foundations. This proven method provides a continuous, solid concrete base for the masonry walls of the new homes, ensuring exceptional long-term structural integrity. We specifically adapt our shallow foundations for plots requiring special measures to protect nearby tree roots, ensuring environmental compliance alongside structural stability.

CFA Pile Foundations and Piling Works

For the heavier flat blocks and plots where ground conditions demand deeper support, we execute specialist piling works. We utilise Continuous Flight Auger (CFA) pile foundations, drilling deep concrete piles into the earth to bypass weaker upper soil layers. This transfers the structural load securely down to the solid ground below. We provide continuous logistical support and working platforms for the piling rigs to ensure this highly technical phase is completed safely and accurately.

Advanced Drainage and Water Management

Effective water management remains a cornerstone of modern residential development. At Navigators Walk, we design and install a highly sophisticated drainage network capable of handling the heavy demands of a 250-plot estate.

Our teams manage the precise excavation and installation of all deep drainage networks, including mains storm and foul drainage systems. We utilise a combination of deep and shallow infiltration techniques to manage water effectively across the site's varied topography. This includes the installation of deep bores and large-capacity attenuation soakaways.

To manage the wider site's surface water footprint, we construct massive underground attenuation tanks. These vital features form a crucial part of the site's sustainable drainage strategy. They hold excess rainwater during severe weather events and release it slowly into the natural watercourse. Alongside the main infrastructure, we install the intricate private storm and foul drainage networks that connect directly to each new home.

Constructing Link Roads, Highways, and Street Lighting

Beyond the footprint of the individual homes, Kingsheath Construction delivers the vital physical networks that connect the Navigators Walk community. We manage the full construction of all necessary road networks, private access routes, and pedestrian pathways.

A flagship element of this project is the construction of a major new spine road. This crucial link road connects Nash Road directly to Manston Road, improving traffic flow and providing primary access for the entire estate. Alongside the spine road, we construct all adoptable standard roads to the exacting specifications of the local highway authority, ensuring a smooth handover for future public maintenance.

We also construct the private access roads, footpaths, and vehicular crossovers that provide safe, reliable entry points for future residents. To ensure safety and visibility across the completed development, our team manages the comprehensive installation of both adoptable and private street lighting throughout the site.

External Works, Utilities, and Final Landscaping

The final phase of our massive groundworks package focuses on the visual and practical finishing touches that transform a bustling construction site into a welcoming, high-quality neighbourhood.

Our team excavates and installs all mains service trenches and associated works across the development. We coordinate closely with statutory utility providers to ensure water, gas, electricity, and telecommunications infrastructure drops perfectly into our prepared trenches without delaying the build programme.

Our external works teams deliver exceptional hard and soft landscaping across the entire 250-plot development. We handle the precise installation of house paths, high-quality patios, and all associated items that expand the living space into the outdoors. We construct durable private drives, designated parking areas, and shared access courts to ensure ample, well-finished parking solutions for every resident.

Furthermore, we execute the complex groundworks required for the broader site architecture. We construct deep foundations to support external garden screen walls and structural retaining walls, which allow us to safely manage varying ground levels. By applying expert attention to detail during the final hard and soft landscaping phases—including the preparation of public open spaces and play areas—we ensure Navigators Walk looks immaculate upon completion.

This £19 million project perfectly highlights our immense capability as a trusted Principal Contractor and leading groundworks partner in Kent. We possess the specialist skills, heavy equipment, and dedicated project management expertise to deliver massive, multi-phase infrastructure works to an exceptional standard, strictly on schedule, and securely within budget.
