This had been due to be ready in December but old mine workings, running sand and rock layers have hampered the installation of steel columns to carry power cables for electric trains.

It required excavations that ranged from 20-feet deep to 32-feet deep, had an active 21-inch sanitary sewer line running through one of the pits, a pond directly next to another of the pits, a creek less than 12-feet away, had a mix of sticky clay soil and running sand, there was an apartment building nearby, and also had a highly traveled road 15-feet away.
The union's determination to secure its own water supply (and not have to buy for a water company) obliged the contractor to dig down through running sand before reaching the bedrock, and excavation took some 16 months.
We typically deal with such challenges as river crossings, bridge spanning, wetland crossings, mature landscaped areas and a variety of soil conditions from solid rock to running sand. We have developed extensive, detailed specifications that have been thoroughly field tested and filed with the Public Utility Commissions.
The job involved the excavation of hundreds of tonnes of sand on a daily basis to allow construction of the base layers, digging holes over 5m deep in running sand, and working around a vastly challenging tidal climate.

Area ground conditions dictated substantial dewatering, including well-point dewatering to stabilize the trench excavation in the predominantly running sand environment.
Soil cores taken of the area along the route of the pipe showed that the pipe was situated in running sand. Running sand exists when the surrounding water table is so high that sand lying between layers of clay actually moves.
