Our team from Infra-Spezialtiefbau is on the road in Conneforde - where we have been commissioned with the bored pile foundations for overhead line pylons. Up to eight inclined piles with an inclination of up to 8° are being installed at each pylon site. The diameters of the piles vary from 1.0 metres to 1.5 metres! The challenges in this construction project are the inclined piles, the logistics and working in a confined space. The logistics behind the project are one of the most demanding tasks, as the team often has to complete the foundations for a pylon site within a week and then move to the next construction site.
With two drilling rigs, this can require up to four moves per week, with each rig having to be moved with a heavy transport of around 29 metres over poorly developed and narrow farm tracks. The construction site equipment is then additionally transported by lorry. Depending on the diameter and depth of the piles to be drilled, this can involve up to 12 lorries per move.
For this contract, Infra-Spezialtiefbau is working closely with our Eiffage Infra-West, as the team is not only responsible for the bored pile work, but also for the excavation pits, concrete foundation work, steel installation work and groundwater drainage, including post-treatment.
One of the biggest challenges is to reconcile the preliminary work of our client with the coordination of our subcontractors, because the work processes have to run hand in hand to keep the construction site running, but only together can we achieve great things and literally ‘aim high’!
As Eiffage Infra-Bau, we are pleased to be able to offer everything from a single source with our companies.
