Site Work & Civil Infrastructure

What We Offer

Earth Work

Before the real work can begin, you need a trusted team who will give your site the treatment it needs. We perform site surveying, grading, leveling, clearing, drainage, earthmoving, demolition, and more to give you a clean slate to build on.

Walls

Having built the tallest free-standing wall in New England, we understand how to build long-lasting and effective walls to keep soil and other materials in place. You can rely on our walls to be built on time and to exceed specifications and standards all within your budget.

Aggregates

Onyx offers a variety of solutions to process material onsite to meet specifications required for reuse, and mitigate waste/export costs. Learn more about our pit operations and aggregates by visiting our Aggregates and Organics page.

Drainage Installation

Whether installing new drainage systems or replacing existing drainage, Onyx has experience across both private and public projects. We pride ourselves in getting engaged during the initial project planning process to provide value engineering solutions through our extensive drainage experience and resources.

Project Management

There’s dozens, if not hundreds, of moving parts that go into any construction project. It takes a team with years of knowledge, organizational skills, and effective communication to keep the work running smoothly.

Utility Work

We offer utility work services to ensure that your project has access to reliable and efficient utility systems. We’re equipped to handle a variety of utility installations and improvements, including water, sewer, gas, and electrical. Our team stays up-to-date on the latest technology and techniques to benefit each project’s specific needs.

We understand the rigorous standards needed to meet not only state regulations but the precise expectations of a high-end custom home builder. This range of experience allows us to help you with the initial stages of planning, value engineering, or peer-reviewing your project to ensure you’re getting the most for your budget.
