Underground Utility Installation in Central Florida
Storm sewer, sanitary sewer, water main, and fire line — installed to permit, tested to specification, and documented with as-builts. We coordinate Sunshine 811 locates, utility authority tie-ins, and every step in between.
Who installs underground utilities on a commercial site?
A site utility contractor installs the storm sewer, sanitary sewer, water main, and fire line systems that connect a building to public infrastructure. The work includes Sunshine 811 locates, trenching and bedding, structure setting, backfill compaction, pressure and CCTV testing, and as-built delivery. Earthscapes self-performs this entire scope in Central Florida and coordinates directly with local utility authorities for tie-ins and inspections.
What Keeps GCs Up at Night on Utility Scopes
Underground work is schedule-critical and invisible once buried. We've seen every problem in the ground — and we work to keep them off the weekly report.
Unmarked or mismarked existing utilities
Florida's dense development history means conflicts between new and existing infrastructure are common. Late discovery during excavation can stop a critical-path activity immediately.
Utility authority inspection hold-ups
Sewer and water tie-ins require scheduled authority inspections that can slip if submittals aren't tracked or if the contractor isn't proactive with the utility company's project coordinator.
Failed compaction under pavement
Settlement beneath paving caused by under-compacted trench backfill creates warranty callbacks and paving failures. Lift-by-lift density testing is the only way to prevent it.
Incomplete closeout documentation
Permits can't close without as-built drawings, test reports, and video inspection records. Missing a single deliverable at the end of a job delays certificate of occupancy for everyone.
Underground Utility Capabilities
We self-perform the full underground scope — pipe, structures, bedding, backfill, and testing — so nothing falls through the cracks between trades.
Storm Sewer Systems
Installation of reinforced concrete pipe (RCP), HDPE, and corrugated metal pipe for site storm conveyance. Includes catch basins, manholes, junction boxes, and outfall structures.
Sanitary Sewer Mains & Laterals
PVC gravity mains, manholes, cleanouts, and service laterals installed to local utility authority specifications. Proper grade and alignment are verified before backfill.
Water Main & Fire Line
Ductile iron and PVC water mains, fire hydrant assemblies, gate valves, and detector check assemblies for domestic and fire suppression service.
Sunshine 811 Coordination
We submit locate requests through Florida's Sunshine 811 system and manage utility marking verification before every dig — protecting existing infrastructure and satisfying state law.
Conflict Resolution
Field identification and resolution of conflicts with existing buried utilities, including crossing designs, horizontal adjustments, and coordination with serving utility companies.
Trench Backfill & Compaction
Lifts placed and compacted per geotechnical specifications. Density testing coordinated with the project's testing laboratory to satisfy permit and building-department requirements.
Pressure & Video Testing
Hydrostatic pressure testing on water mains and fire lines; post-construction CCTV video inspection of gravity sewer mains to verify grade, joint integrity, and clean pipe.
Record Drawings (As-Builts)
Field-verified as-built drawings prepared for submission to the engineer of record, local utility authority, and permitting agency at project close-out.
How We Execute Underground Utility Work
Sunshine 811 Locate & Pre-Construction Meeting
All underground utilities are marked and verified via Sunshine 811 before any excavation begins. We conduct a pre-construction meeting with the GC and utility authorities to review sequence, tie-in points, and shutoff procedures.
Trench Excavation & Bedding
Trenches are excavated to the required depth and width. Pipe bedding material is placed and screeded to proper grade, verified by a crew member before pipe is set.
Pipe Installation & Structure Setting
Pipe sections, manholes, valve vaults, and junction boxes are set in sequence. Joints, gaskets, and connections are inspected as work progresses.
Backfill, Compaction & Surface Restoration
Select fill is placed in controlled lifts and compacted. Density testing is performed per the project geotech report. Surface restoration — base rock, pavement, or sod — follows promptly to reduce open-trench time.
Testing, Punch-List & As-Builts
Pressure tests and video inspections are conducted, punch-list items corrected, and as-built drawings delivered to the engineer and authority of record before substantial completion sign-off.
