Coastal Mechanical was awarded the 2021 ABC Excellence in Construction Eagle Award.

This project included a complete mechanical equipment overhaul consisting of removing 2 original chillers and installing 2 new 225 ton chiller units.  All four units were removed and replaced on the same day.  On a 63 day schedule, this challenging job was executed to perfection with removing and reinstalling 150 pieces of equipment, associated piping, and duct work.
