Calexico, CA Multiple bores of 28” SDR 11
California Boring worked direct for Abiensa EPC on the Mount Signal Solar Project in Calexico California, to install the solar farms power lines under 7 canals surrounding the project. The bores consisted of numerous lengths up to 800’ of 24” and 28” SDR 17 HDPE, with up to 10 HDPE inner ducts.
California Boring did the bores turn-key and supplied all fused all HDPE casing, all HDPE inner ducts, Spacers, Dug bore pits, Grouted inside annulus of casing, and left for customer. The customer was able to come in, pull the cable and move onto the next location without worrying about any logistics of the boring operation.
A challenging factor to this project was the desert heat, with temperatures reaching over 100 degrees almost every day, heat illness prevention was critical. California Boring put all of their employees though heat illness training, and had a mandatory acclimation period for all new workers. The acclimation period consisted of slowly increasing hours throughout the week with close supervision to get the employees used to the tedious conditions. California Boring was able to walk away with 0 safety incidents on the project and finish a week ahead of schedule.

2000’ bore of 12” Steel Ontario CA
Prior to a grade separation in Ontario, Ca, California Boring was hired to move a natural gas pipeline so the grade work could begin without interference of substructures. The run consisted of re-routing a 12” steel pipe below a busy intersection and through the tight confines of an industrial complex. Due to depth and other grade separation work taking place, the traditional open trench method was cost prohibitive. Working together with their customer, California Boring was able to complete the bore in 6 days.
