Ahtna Engineering Services, LLC (AES) performed the construction of a well, arctic pipe, and electrical component installation at the Bureau of Land Management (BLM) Chicken Field Station and the well installation at the Walker Fork Campground. Previously, the water had been transported by truck to these locations. To execute the work, AES conducted a site survey to pinpoint the location of the well and verify that it is 200 feet away from any vault toilets or septic systems. Prior to fieldwork, our staff completed utility locates and cleared vegetation as required.

AES drilled a new well with pump and controls to approximately 450-feet-deep at the BLM Chicken Field Station. Heat trace was installed in the well to a depth of 70 feet. Well development and hydro fracturing were completed as required. We also provided test pumping, sampling, and cleaning of the well. 

The location of the arctic pipe was surveyed prior to excavation to verify elevations, grade, a minimum of 10-foot distance from vault toilets or septic systems, clearing boundaries, and water line location. Vegetation was marked and cleared as required between the propane tank and the water tank on site. All underground utilities were located including the anticipated propane line.

AES performed trenching in sections in the roadway area to maintain vehicles access to all areas of the station. Open trenches were clearly marked with barriers to direct traffic around the trenches. The removed soil and gravel was placed to the side of the trench to be used later as fill. AES placed arctic pipe, assembled in 20-foot sections in the trench at a depth of 4 feet or deeper as required to maintain grade for proper drainage. Heat trace was threaded through the 440 feet of arctic pipe. Stub ups for heat trace was provided for power supply wires. The water line was installed into the existing water tank along with a float switch on the high elevation end and attached to the well pitless adapter on the low elevation end. AES tested and cleaned the water line per the specifications.

All electrical components were installed by our subcontractor. This included four junction boxes with posts, one new panel, one pump controller, wiring to heat trace, pump and float switch, connections to existing panel and generator, and installation of conduit. Trenching, barriers, clearing, locates, and surveying for conduit runs will be similar to as described above for the arctic pipe trenching.
