Our clients can rest assured, when they commit to green construction, and engage HEI Civil for their infrastructure construction, that commitment goes all the way down to the ground.

Heavy equipment engine progression towards clean emissions is measured in tiers, with the most environmentally responsible machines earning Tier 4 Final designation. These machines are significantly more expensive to purchase, but greatly reduce the environmental impact of carbon emissions in our environment on any construction project.
