Francisco Rubio in the field.
On SW 7th Street, DoubleDay Engineering tapped an existing 12-inch water main to feed a new 6-inch hydrant line and a 4-inch fire sprinkler service under the strict requirements of FDOT and Miami-Dade WASD.
Resolve the violation. Recertify the building. Close the case.
These are not side services for DoubleDay. We help owners move from a notice, failed inspection or open building case to a defined engineering path, corrective work and documented compliance.

Francisco Rubio and the SW 7th Street utility operation.
Recent work has required the team to execute in tight nighttime windows while coordinating excavation, utility crews, inspectors, roadway access and restoration requirements.
Francisco Rubio has been the field connection between the engineering plan and the crews performing the work. The operation included tapping an existing 12-inch water main, installing a 6-inch fire hydrant line and a 4-inch fire sprinkler service, and coordinating excavation, inspections, traffic constraints and restoration under the strict requirements of FDOT and Miami-Dade WASD.
Current field scope: roadway excavation, underground utility installation, inspections, compaction and restoration coordination.
