Woltman 90 DR builds foundation for new terminal in San Francisco

Currently, no less than four Woltman 90 DR drilling rigs are working at the airport of San Francisco. In several months, the complete foundation of a new terminal will be built, after that the current terminal will be teared down.
During this impressive project, 1655 piles will be installed, all with a diameter of 18-24’’. The steel casings have a length up to 127 ft. In order to stick to the deadline, pile drivers work in 10 hours shifts from Monday to Friday. Four Woltman 90 DR drilling rigs are equipped with PVE rotary heads, with a special clamping system in order to install the steel casings.
The average number of driven piles per day is 7, as the pile drivers need to in-bed the piles into a rock socket, to guarantee the load capacity of a pile. As data records must be made, the on-board data acquisition system is a very helpful tool.
Apart of the deadline, one of the great challenges of the project is the strict rules due to air traffic and fuel from planes. Foundation Contractors made a tight schedule and they are sure to finish the job within the deadline.

Three Woltman machines at work at the same project

Due to the quick growth of supermarket chain Lidl, the company is in the need for a new distribution center. Moerdijk, a city located in the west of the Netherlands, is the place where this distribution center will be built. In only two months’ time, 3500 piles need to be piled into the soil, an enormous project with a strict deadline. In order to achieve this deadline, contractor Voorbij Funderingstechniek partnered up with Terracon Funderingstechniek and Ballast Nedam. Three Woltman 160PR piling rigs are used to drive the 40m piles into the solid ground. Due to the stability and low center point of gravity, these drilling rigs are the perfect machines to do the job.
