The items were seized after a six-week investigation into break-ins in houses under construction and garages, and thefts from vehicles, in Vancouver and Richmond.
Police say 10 victims have already been identified , but much of the construction equipment — including pricey materials, tools and trailers — has not been identified.
"Many of these victims were independent contractors who lost work from the theft of their tools," said Det. Const. Phil Ens. "The tools were their livelihood and without them they could not fulfill contracts and could not support their families."
Police say they plan to recommend charges against four people for break and enter, possession of stolen property, theft and trafficking in stolen property.
