In January, a section of the Heathrow fire main burst on the busy A30 road, adjacent to our Eastern Balancing Reservoir construction site. In order for repairs to begin, RK Air had to respond fast to install and commission the Northern Main at the Surge Vessel such that the fire main supply could be [...]
The next phase of the LHR Eastern Balancing Reservoir Surge Vessel works is underway. Having established a temporary Surge Vessel and the temporary bypass pipework, the de-commissioning of the old 10 metre long, 3 metre diameter Surge Vessel weighing 19 tonnes can be completed. This involves the removal of the wall to the pump house [...]
Another project at the Eastern Balancing Reservoir involving complex installation and welding of a number of steel fittings and grates within the camp 4 pumping station. Having been fabricated off-site, the steelwork had to be lifted in and installed in stages using a crane. You can see the scale of these grates from one of [...]
This project is divided between several areas airside and landside. There are 12-15no separate zones where works are required to be carried out in a variety of complex environments. The project involves breaking into existing 600mm diameter fire mains, and replacement of fire hydrant and valves in addition to completion of civils works that [...]
Works have continued at the British Airways Maintenance Base where we are to replace a further 4no hydrants and 15no valves across the base, including all associated civil works and full reinstatement of the apron. Working closely with our client, tight timeframes around short isolations are critical so that operational standards remain in place [...]
Another project at the Eastern Balancing Reservoir. Here, RK Air is to install 4no manhole chambers and the connecting concrete pipework and push-fit ductile iron, in addition to a valve chamber that houses 2no 400mm actuated gate valves. The project includes all associated civil and temporary works systems. It will then be connected to the [...]
This project includes the installation of pipework within a temporary bypass constructed from concrete culverts above ground, and then connecting it to existing pipework below ground. RK Air's task encompasses all associated civil works, the excavations and temporary works systems before reinstatement takes place. A temporary surge vessel is to be installed while the old [...]
RK Air’s works here are to install new LTHW heating mains to accommodate new connections to the future CHP header building, and also to upgrade existing pipework circuits. This is within a challenging confined spaces environment in the Terminal 3 service tunnel, zones 18-20. The project team is working a mix of night shifts and [...]
A project to re-paint all the lines and signs on the British Airways East and West maintenance bases, and replace the cat’s eyes on the base. Prior to the new lines being painted, the old lines had to be removed. This was done using captive blasting. Cores were drilled for the cat’s eyes, before being [...]
RK Air replaced and installed 500Dn all flanged Ductile Iron pipework across the LHR Eastern Balancing Reservoir middle pond bridge. We used a barge to get the pipework into position, and deployed a floating pontoon as a safe working platform for the operatives. The pipework was then fixed to custom-made bracketry. Despite the adverse working [...]
