HVO Fuel Tank Installation

On this project, the job required the collaborative efforts of both our Civil and Installation teams. The scope of work was to install an above-ground HVO fuel tank for one of our Aerospace clients in the South West.


The job was carried out in two phases. The first phase included the construction of a concrete pad for the HVO tank to be installed on, ACO drainage, and the hardstanding for the vehicle refuelling. Once the foundation was set, the second phase of the job was to install the 25,000-litre fuel tank. The additional fuel storage was put in against an adjacent fuel pump.


Works were scheduled over a four-week period.

At the onset of the project, all plant, equipment, and Heras fencing were delivered to the site. The team mobilised to initiate the setup process, ensuring that the fencing was installed in alignment with the designated site boundary.

  • The boundary area was marked out, ready to be broken out.
  • The boundary line was cut out using a floor saw.
  • Once cut, the tarmacked area was excavated with a 360-degree excavator with a hydraulic breaker attachment.
  • Sub-level was dug down to depth as approved by the project manager.
  • Excavated area was compacted topped up with MOT type 1 and then compacted using a wacker plate.

  • The road pans were fitted into place to form the shuttering, ready for the concrete pour.
  • The DPM and mesh reinforcement was installed, followed by the concrete pour.
  • Concrete was compacted with a vibrating beam and brush finished with a trowel edge.
  • The ACO drainage was installed and connected up to the existing drain, and the shoulders were finished off.
  • The tank plinth was formed using the same method.
  • Once the concrete was cured, engineers applied Colpor to the concrete joints.
  • The tank was lifted and positioned onto the prepared concrete plinth by HIAB, ready for electrical installations.
  • Power supply was installed to the new tank including the distribution board, pump, lights, and emergency shut-off switch.

To efficiently concluded the project, coordination with all hire suppliers was imperative for the removal of plant, equipment, and welfare facilities from the site.

Once welfare facilities were transported off-site and the site cleaned up, a final inspection was conducted to confirm the complete removal of equipment, plant, fencing, and welfare facilities.

The client was provided with a full set of O&Ms with all relevant documentation. Site was now ready to be handed over to client.


Executed in two distinct phases, the construction of a robust concrete pad to serve as the foundation for the tank and the refuelling of vehicles.

Subsequently, the Installation team carried out the installation of the 25,000-litre fuel tank, adhering to industry standards and client specifications.

The project was delivered on time and in budget, meeting both functional and client satisfaction objectives.
