(05/12/17) - Vandals are delaying pipe replacements in Flint.

Crews got to work Friday morning, ready to replace pipes on Flint's north side, but they found a $70,000 truck burned and completely destroyed. It didn't stop there - about seven vehicles and heavy machinery had windows busted out.

The equipment belongs to two contractors who are in the city, hired to replace pipes.

Hardrock Drilling and Excavating, out of Jackson, lost that truck that was likely set on fire and had damage to several other pieces of equipment. Gustafson Excavating, based near Muskegon, is dealing with windows broken out.

They're speculating this happened around 2 a.m. after someone who lives nearby the former Bryant Elementary School off Pierson Road called 911. They reported seeing something suspicious in the lot where the equipment is parked.

The project manager with Hardrock says they've been using the lot for about a week so they don't have to transport equipment back and forth.

The crews were planning on digging up lead pipes at 8 homes in the city on Friday, but now these pipe replacements will not happen.

The companies do have insurance, but it's going to take some time to make a claim and get the equipment back to work.

A spokesperson with Bedrock says they will be looking into how much private security will cost. They're already dealt with broken windows while their equipment was parked at another location in the city.
