When planning any excavation or underground construction work — whether it’s for landscaping, installing conduit, or trenchless drilling — it’s crucial to know what lies beneath. Striking a buried utility can be costly, dangerous, and even deadly. That’s where utility locates and Sunshine 811 come into play.
In this post, we’ll break down the basics of utility markings, what the different colors mean, how the Sunshine 811 system works in Florida, and why it’s essential for any underground utility project.
What Are Utility Markings?
Utility Marking Colors: What Each Color Means
What is Sunshine 811?
Sunshine 811 is:
- Required by Florida law for any excavation.
- Free to use, protecting both workers and underground infrastructure.
- Available to homeowners, contractors, and businesses alike.
How the Sunshine 811 Process Works
- Submit a Locate Request Call 811 or visit www.sunshine811.com at least two full business days before you dig.
- Wait for Utility Markings Utility companies will send locators to mark their lines using the appropriate color codes.
- Verify the Marks Ensure all utilities are marked before excavation. If something’s missing, contact Sunshine 811 again.
- Respect the Tolerance Zone Florida law mandates a 24-inch tolerance zone on either side of the utility marking. Use hand tools in this zone to prevent damage.
Why It Matters for Trenchless Drilling Projects
- Apartment complexes
- Commercial properties
- Schools and government buildings
- Redevelopment projects
Skipping this step can result in:
- Severe utility damage penalties
- Project delays
- Serious safety hazards
Need Help With Private Locates?
Sunshine 811 only covers public utilities — anything owned by the utility companies. But many properties contain private utilities like sprinkler lines, security systems, or secondary electric feeds that aren’t marked by 811.
We offer private utility locating services to ensure every line on your property is accounted for before drilling begins.
