Harbour Constructors is a successor company to Buso Constructors, Inc. founded by Greg Buchanan in 1989.  Buso Constructors’ 18 year construction history was focused in the public works sector with an emphasis on heavy civil engineering projects. Harbour Constructors continues with this same type of work while also focusing on marine structures such as sea walls, docks and piers.


Previous work includes sixteen projects for the State of California, Department of Water Resources repairing and reconstructing the California Aqueduct, State Water Facilities, landslides and road repairs.  Other customers include the Counties of Los Angeles, Orange, and San Bernardino constructing flood control facilities, tie back retaining walls, bridge and pipeline construction. 

Additionally, work for other municipalities include Cities of Anaheim, Needles, Oceanside, Huntington Beach, Los Angeles, North County Transportation District, Los Angeles County Sanitation District, and Ramona Water District building an array of projects from boat marinas with launch ramps, waste water treatment plant improvements, bridges and pier reconstruction.


Prior to the inception of Buso Constructors, Greg Buchanan was heavily involved with Chadwick & Buchanan, Inc in the construction of Cabrillo Beach and Channel Islands boat marinas along with the southerly expansion of the Hyperion Treatment Plant and associated reconstructions of Dockweiler, El Segundo, and Portuguese Bend beaches.
