    Brief

    Sligo County Council is seeking a qualified geothermal contractor to conduct thermal response testing (TRT) at the Sligo Regional Sports Centre. The project involves drilling and completing a new 200-meter grouted vertical borehole heat exchanger that will serve dual purposes: facilitating the TRT test and functioning as part of the facility's final geothermal heating system. The contractor must also install a Distributed Temperature Sensor (DTS) fiber optic cable to the full borehole depth for ongoing temperature monitoring. This is an ideal opportunity for contractors with expertise in geothermal systems, borehole drilling, heat exchanger installation, and fiber optic monitoring equipment.
