Site Work & Civil
Infrastructure
Onyx has a diverse background managing and operating jobs large and small, from excavating for new home foundations and septic systems to complex municipal infrastructure work. 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.
It’s not just our depth of knowledge in excavation that sets us apart. We’re sensitive to the environment in every decision we make, reusing and recycling materials as much as possible, and we have extensive experience working with LEED-certified architects. We are also committed to safety: we’re fully bonded and insured, and our employees are OSHA- or MSHA-certified, with many trained in first aid – which means that you can rest assured that your site will be managed to the highest standard.

Our Process
HOW DO WE WORK?
We take our client’s investment in their dreams seriously. Our professional team will help you design and construct your perfect outdoor space from under the ground up. Click the tabs to the right to get an understanding of our process.
Homeowners should begin by discussing their ideas with Onyx, leveraging our deep knowledge of the field and our industry contacts; Onyx works with a select group of landscape architects and can offer guidance on finding the right fit for your vision.
Once a schematic design is complete, Onyx works with homeowners to meet with contractors, compare options and review details. Onyx then collaborates with you, the landscape architect and our preferred vendors to value engineer our design and provide final pricing that aligns with your budget. Our team will then spearhead the engineering and permitting process in order to secure required permits.
Permits in hand, we can mobilize and excavation can begin. Onyx will guide you step-by-step through the landscape construction process—ranging from gunite pools and plumbing to patios, lawn and lighting, and then to the fun, final step, enjoying your outdoor space!
During this process, Onyx’s full-service team will be onsite, building the landscape of your dreams; including fire features, outdoor kitchens, walkways, retaining walls and plantings. Bringing these elements to fruition can occur simultaneously, and having the right team in place is essential for coordination and efficiency.
Now that you are ready to enjoy your new landscape, the last consideration is upkeep. With your new team in place, Onyx will oversee the transition from construction to maintenance. Your landscape will be carefully maintained, ensuring the success and longevity of your own personal paradise.
