Holocene is providing geotechnical drilling services on both the Sound Transit Northgate and Lynnwood Link Extension projects. Drilling methods on these ongoing, long term projects include a combination of track mounted mud rotary and sonic drilling. Sites are located in difficult, urban settings and have been drilled in both day and night shifts. Holes have been precleared for utilities using Holocene’s vacuum hole clearing trucks. Significant on-site coordination is required to manage traffic control and work hour restrictions. This project also includes well rehabilitation, decontamination, low overhead and angle drilling techniques. Holes are completed between 40 and 140 feet in depth.
