Site Preparation and Groundworks
Every successful installation begins with solid groundwork. At HG Projects, we provide complete site preparation and groundworks services to ensure your power systems are built on a safe, stable and compliant foundation. From excavation to concrete bases, we manage every stage with precision and care.
Preparing Your Site for Safe, Efficient Power Installation
Before a generator, switchgear or flue system can be installed, the site needs to be properly assessed and prepared. Poor groundwork can lead to future complications, including structural instability, drainage issues or safety risks.
Our team ensures your site is ready from day one. We take care of everything, from clearing and levelling to trenching and foundation work, aligning every detail with the specific requirements of your equipment and infrastructure. Whether you’re installing a generator at a commercial unit or upgrading services across a large industrial site, we make sure the groundwork is done right.

Powering a Critical Radar Station Against the Odds
Innovative Engineering for Maximum Reliability
The old generators were carefully removed using a small HIAB vehicle, ensuring zero disruption to critical operations. The new units were positioned over a bunded area to prevent leaks, reflecting a commitment to environmental protection.
To meet ultra-long runtime needs, the generators were equipped with:
- An advanced oil make-up system — featuring a large storage tank and additional filters, extending service intervals to a remarkable 2,000 running hours.
- Deutz oil/air-cooled engines — chosen for their legendary reliability and minimal maintenance requirements.
The control system was strategically configured to ensure continuous power. By alternating runtime between the two sets, operational hours were evenly shared, preventing excessive wear on any single unit. In the event of a failure, seamless backup would ensure uninterrupted function at critical moments.
Our Site Preparation and Groundworks Services Include:
Initial Site Surveys and Risk Assessments
We begin with a detailed survey of the site, identifying any access issues, underground services, drainage needs or environmental concerns. This allows us to plan the work safely, efficiently and in line with local regulations.
Excavation and Clearance
Our team carries out all necessary excavation, including the removal of existing materials, debris or obstructions. We prepare a clean, level area suited to the size and weight of your generator or electrical equipment.
Concrete Bases and Structural Foundations
We construct reinforced concrete pads and bases designed to support the load and footprint of your equipment. All foundations are poured and finished to specification, with built-in fixings and alignment points where required.
Trenching and Cable Ducting
We install cable trenches, ducts and protective sleeves to support power and data connections between equipment. Our trenching services are carefully planned to avoid existing utilities and minimise surface disruption.
Drainage and Environmental Considerations
Where necessary, we implement drainage systems or soakaways to prevent water accumulation around your power systems. We also ensure our work aligns with any ecological or environmental site requirements.
Integration with Full Installation Projects
For clients using HG Projects for generator or switchgear installations, our groundworks services are fully integrated into the wider schedule. This keeps your project moving forward without delays or external coordination issues.
