Hitachi Precision.
BTH Construction is a family-owned excavation company based in Anchorage. Owner and operator Brian Harten grew up around heavy equipment — his father ran a Hitachi UH045 in the mid-80s, and Brian started his own business with a 1999 Hitachi EX160. That tradition continues today with a comprehensive fleet of equipment of all sizes, anchored by two Hitachi ZAXIS 160LC-6 excavators featured in Hitachi Breakout magazine.
"The hydraulics are exact, helping me do my precision grading for foundation pads and driveways," Brian told Hitachi Breakout. That precision is what every BTH client gets — from the smallest residential lot to large commercial site prep.

BTH Construction was featured in Hitachi Breakout magazine when Brian took delivery of a new ZAXIS 160LC-6 — joining a family tradition of Hitachi ownership that stretches back to his father's UH045 in the mid-1980s. The article highlighted BTH's work on a large custom home site overlooking the Anchorage Coastal Trail and Cook Inlet.
