About

Safety & Compliance

The specific practices that keep crews, the public, and existing utilities intact on directional drilling and aerial construction sites.

Safety on an outside plant job is mostly damage prevention and traffic control. Strilla Communications works to Sunshine 811 notice and tolerance zone requirements, holds a documented briefing before every shift, sets maintenance of traffic to the permitting agency standard, and follows excavation protective system rules with a competent person on site.

Damage Prevention Starts with the Ticket

Florida law requires notice to Sunshine 811 before excavation, and the notice window is set by statute rather than by convenience. Tickets are called with accurate limits and a real description of the work, because a vague ticket produces vague marks.

Before a rig starts, the crew reviews positive response from every member utility on the ticket. A missing or unclear response is resolved before excavation, not treated as permission to proceed. Tickets are refreshed before they expire on longer runs.

Marks are compared against the design, against visible surface evidence such as pedestals, valves, meters, and risers, and against available facility records. Where those disagree, the conflict is resolved in the field before the head goes in the ground.

Tolerance Zone and Utility Exposure

Florida establishes a tolerance zone on either side of a marked facility where mechanical excavation is not permitted. Inside that zone we use hand digging and vacuum excavation to expose the facility and confirm its actual depth and alignment.

For directional drilling, exposure is not optional at crossings. Potholing at each crossed utility gives the operator a verified depth to steer against rather than an assumed one, and the exposure is recorded so the as-built shows how clearance was confirmed.

Bore path planning takes those exposures into account before the bore begins. Depth, pitch, and separation are planned to clear existing facilities with margin, and the tracking operator monitors position continuously through the crossing.

  • Ticket called and positive response confirmed before excavation
  • Marks verified against design, surface evidence, and available records
  • Hand and vacuum excavation inside the tolerance zone
  • Verified depth at every crossed facility before boring through it
  • Stop work and re-verify when field conditions do not match the marks

Daily Safety Briefings and Stop Work Authority

Every shift begins with a documented briefing covering the day scope, the utilities in the work area, traffic conditions, weather, equipment assignments, and the specific hazards of that location. It is a short meeting held at the site, not a form signed in the truck.

Conditions change during the day, so the briefing is repeated when the work moves, when the crew composition changes, or when something unexpected appears. Every crew member has stop work authority, and using it is expected rather than tolerated.

Near misses and utility contacts are reported the same day. A near miss that is not reported is a strike waiting for the next crew.

Maintenance of Traffic

Most of this work happens in a right of way. Temporary traffic control is set to the standard the permitting agency requires, following the applicable state and national traffic control standards for the road classification, posted speed, and duration of the work.

Setups are installed before work begins and inspected through the shift. Lane closures, shoulder work, sidewalk closures, and pedestrian routing are handled as scoped work with time in the schedule, because an inadequate setup shuts a job down as fast as an equipment failure.

Flagging positions are staffed according to the requirements of the permitting agency and the approved traffic control plan for the location.

Excavation Safety and the Competent Person

Excavation work follows federal excavation safety requirements and Florida trench safety requirements. Entry pits, exit pits, handhole and vault excavations, and open cut work are evaluated for soil classification, water, spoil placement, and access before anyone enters.

A competent person is the individual on site with the knowledge to identify hazardous conditions and the authority to correct them immediately, including ordering personnel out of an excavation. That role is assigned on every excavation, and the person holding it inspects the excavation daily and after any condition that could change stability.

Florida water table and sandy soils change trench behavior quickly, particularly after rain. Protective systems are selected for the conditions on the day, not for the conditions on the plan sheet.

Personal Protective Equipment

PPE requirements are consistent across our work: head protection, high visibility apparel appropriate to the roadway environment, eye protection, appropriate gloves for the task, protective footwear, and hearing protection around drilling and vacuum equipment.

Fall protection is used in aerial lifts as a standing rule. Additional task specific protection is added for splicing, fluid handling, confined space entry where applicable, and any work the site conditions require.

Utility Strike Prevention as a System

No single control prevents strikes. What prevents them is the combination: an accurate ticket, verified positive response, physical exposure inside the tolerance zone, a planned bore path, continuous tracking, an operator who stops when the readings do not make sense, and a crew that is allowed to say so.

That system is also what protects your schedule and your relationship with the jurisdiction, which is why we treat it as production work rather than overhead.

Documentation and Prequalification

Safety program documentation, written policies, training records, and loss history are provided for owner and general contractor prequalification on request. Experience modification rate and current safety statistics are provided in prequalification packages on request, taken directly from the source records.

What Do the Locate Mark Colors Mean?

Locate marks follow the APWA uniform color code, so every crew reads the same paint the same way. Each color identifies a type of facility, and the marks show its approximate horizontal position, not its depth. Our crews check that every color expected on the ticket is present before excavation starts.

  • Red: electric power lines, cables, conduit, and lighting cables
  • Yellow: gas, oil, steam, petroleum, or other gaseous materials
  • Orange: communication, alarm or signal lines, cables, or conduit
  • Blue: potable water
  • Purple: reclaimed water, irrigation, and slurry lines
  • Green: sewers and drain lines
  • White: proposed excavation limits marked by the excavator
  • Pink: temporary survey markings

Heat, Lightning, and Florida Weather

Florida weather is a safety hazard in its own right. Summer heat and humidity put field crews at risk of heat illness, especially in full PPE beside hot pavement. Crews work with water, shade, and rest breaks built into the day, and heavier tasks are moved earlier in the shift when the forecast calls for extreme heat.

Lightning is the other constant. Afternoon thunderstorms build quickly across Central Florida, and a crew in an aerial lift or beside a steel drill string is exposed. Aerial work and drilling stop when lightning is nearby, and work resumes only after the storm has clearly passed, commonly following the guidance to wait 30 minutes after the last thunder.

Heavy rain also changes ground conditions. Excavations are re-inspected after rain, outrigger footing is rechecked, and traffic control devices are reset before work continues.

Key takeaways

  • On outside plant work, safety is mostly damage prevention and traffic control, backed by a documented briefing before every shift.
  • Florida's tolerance zone extends 24 inches on either side of a marked facility, and only hand digging or vacuum excavation is used inside it.
  • Strilla Communications confirms positive response from every member utility on a Sunshine 811 ticket before any excavation begins.
  • Every crew member has stop work authority, and near misses are reported the same day.
  • Florida heat and afternoon lightning are planned hazards, with aerial work and drilling stopped while lightning is nearby.

Key terms

Tolerance zone
The area 24 inches on either side of the outside edge of a marked underground facility, as defined under Chapter 556, Florida Statutes. Mechanical excavation is not permitted inside it. Excavators expose facilities in the zone by hand digging or vacuum excavation before working near them.
Positive response
The confirmation each member utility on a Sunshine 811 ticket provides to say its facilities have been marked, are clear of the dig area, or need further contact. Excavators review positive response before starting work. A missing or unclear response is resolved first, not treated as permission to dig.
Competent person
A person on an excavation site who can recognize existing and predictable hazards, such as cave-in, water, or hazardous air, and who has authority to correct them immediately. OSHA excavation rules require one for every excavation, with daily inspections and checks after rain or other changes.
Maintenance of traffic
The temporary traffic control used to protect workers and the public around a work zone in or beside a road, often called MOT. It includes signs, cones, arrow boards, lane closures, flaggers, and pedestrian detours, set to federal and state standards and to the conditions of the permit.
APWA uniform color code
The national color scheme for marking underground facilities, published by the American Public Works Association. Red marks electric, yellow gas and oil, orange communications, blue potable water, purple reclaimed water, green sewer, white proposed excavation, and pink temporary survey marks.

What this means for your project

A safety failure on an outside plant job is also a schedule failure. A utility strike stops work, brings in the facility owner and the jurisdiction, and can lead to repair bills and damage claims that land on the project. A traffic incident can shut down the permit. Prevention costs far less than any of those outcomes.

For the project file, the safety record and the construction record overlap. Locate tickets, pothole records, traffic control photos, and daily briefings show that work was performed to the statute and the permit, which matters if a claim or an inspection question comes up after the crew has left.

Ask every contractor how they handle positive response, potholing, and stop work, and ask to see the records. The answers tell you how much risk your project will carry.

Frequently Asked Questions

Who calls in the locate tickets?
We do, for our scope, unless the contract assigns that to another party. Tickets are called to Sunshine 811 with accurate limits and a clear description of the work. Positive response from every member utility is confirmed before excavation starts, and tickets are refreshed before they expire on longer runs. Ticket numbers are carried into the daily report for each day of work.
What happens if the locate marks are wrong?
Work stops in that area and the conflict is resolved before excavation continues. That usually means vacuum excavation to expose the facility, a call back on the ticket for a re-mark, and a check against the design. The condition is reported to your point of contact the same day and written into the daily report, so the record shows what was found.
Do you provide traffic control or do we?
We provide maintenance of traffic for our own work zones, set to the standard the permitting agency requires for the road classification, speed, and duration of work. If the project supplies traffic control under a separate contract, that is confirmed during planning so nobody assumes the other party has it. Either way, the setup is in place before work starts.
Can you supply safety documentation for our prequalification portal?
Yes. Written safety program documents, training records, loss history, and experience modification rate information are provided for owner and general contractor prequalification on request. Send the portal invitation, the requirement list, and the deadline to hello@strillacommunications.com. We return the completed submission and keep it current as records are updated.
What is the tolerance zone in Florida?
Under Chapter 556, Florida Statutes, the tolerance zone extends 24 inches on either side of the outside edge of a marked underground facility. Mechanical excavation is not allowed inside that zone. Crews expose facilities there by hand digging or vacuum excavation to confirm actual depth and alignment, which is why potholing is planned at every crossing on a directional bore.
Who is the competent person on an excavation?
The competent person is the crew member assigned to each excavation who can identify hazards such as cave-in risk, water, or bad air, and who has authority to fix them at once. That person inspects the excavation daily and after rain or any change that could affect stability. They can order everyone out of the excavation without asking anyone first.
Can any crew member stop work?
Yes. Every crew member has stop work authority, and using it is expected rather than merely tolerated. If a reading does not make sense, a locate looks wrong, traffic control fails, or weather turns, anyone can stop the task. Work restarts once the condition is resolved and the crew is briefed again. Near misses are reported the same day.
