Project Details

Location: Red Rock, Pinal County, Arizona
Owner: Pulte Homes

Scope: New infrastructure for a new 1500 lot subdivision.

Borderland’s Komatsu PC1250 trackhoe excavator weighs in at 244,000 pounds and is capable of digging an 8-feet wide flat bottom trench at a depth of 37’-9”. The PC1250 proved effective at installing new sewer lines at depths that exceeded 32’ and has the horsepower to easily relocate 30,000-pound shoring boxes. In addition, Borderland fabricated specialized shore box trailers to quickly and efficiently move shoring along excavated trenches.
