Who We Serve
General Contractors
TLDR
General contractors need a utility subcontractor who does not become the reason a milestone moves. Strilla Communications performs directional drilling, conduit, and fiber work inside active job sites across Volusia County and Central Florida, coordinates with the trades ahead of and behind us, and turns in restoration and closeout documents on time.
What this role is usually worried about
- A subcontractor no-show turns into a superintendent explaining a schedule slip that was never his to cause.
- The bore has to happen between grading and paving, and that window is short and moves without warning.
- Utility work damages an existing line on an active site, which stops other trades and creates an incident report.
- Restoration is left short of site specification, so it lands on the punch list weeks later.
- Closeout documents the owner requires arrive late from the sub, holding retainage for everyone.
- Nobody from the sub answers the phone when the site plan changes on a Friday afternoon.
Your Schedule Is the Constraint, Not Ours
On a general contractor's site, utility installation is almost never the critical path by itself. It becomes critical when it slides into somebody else's window. The bore that had to happen before base was placed, the conduit that had to be in before the sidewalk was formed, the service that had to be pulled before the building could be energized.
We plan around those interlocks. Before mobilization we want to know what happens immediately before us and immediately after us, what has to be inspected between those steps, and who signs it off. Then we commit to a window and hold it, or we tell you early enough that you can resequence rather than absorb it.
Owned equipment matters for this reason more than any other. A crew that depends on a rental yard cannot promise a Tuesday when the site needs Tuesday.
Working Inside an Active Site
An active site has other trades, deliveries, inspections, and an owner walking through. Utility work has to fit into that without generating incidents. That means locates before digging even when the site is already disturbed, potholing where the plan puts us close to an existing line, and keeping spoils, drill fluid, and equipment out of the way of everyone else's work.
Fluid management is where most complaints start on a job site. Containment, cleanup, and disposal are planned rather than improvised, because a slurry track across finished pavement or into a stormwater inlet becomes the superintendent's problem within the hour.
Site access is planned in advance too. A bore setup needs a footprint for the rig, the fluid system, and the pipe, and that footprint should be agreed with your superintendent before the truck arrives rather than negotiated in the middle of a delivery window.
- Locates and potholing before excavation, including on previously disturbed ground.
- Bore crossings under drives, pavement, and hardscape that is already placed.
- Conduit, tracer wire, and handhole placement coordinated with grading and paving.
- Drill fluid containment and cleanup planned before the rig arrives.
Restoration to the Standard the Job Requires
Restoration is a schedule item, not an afterthought. Sod, pavement, curb, sidewalk, driveway aprons, and irrigation get restored to the site specification, and we would rather do it correctly the first time than argue about it during punch list.
That standard also applies off site. Where a bore pit or a receiving pit sits in adjacent right of way or on a neighboring property, it gets restored to the same finish. The complaint that reaches the owner about a neighboring yard reflects on the general contractor, not on the subcontractor who left.
Communication a Superintendent Can Use
You get one point of contact who is reachable during the workday and who knows what the crew is doing. Daily production reporting covers what was completed, what is planned next, and anything that changed in the field.
When a conflict is found underground, you hear it while the hole is still open, with a description of what was found and the options for getting around it. Discovering a conflict at the end of the week, after the concrete is scheduled, is how a two hour decision becomes a two week delay.
Our foreman can attend the weekly schedule meeting when the job warrants it. Conflicts between our work and another trade surface there as calendar items rather than as arguments on the morning a crew shows up to a work area that is not ready.
Closeout Without Chasing Paper
We deliver as-built drawings, photographs of installed and buried work, and the documentation the owner or engineer requires for acceptance. Those records are collected during construction so the package is ready when the job closes rather than reassembled from memory during retainage discussions.
If your closeout has a specific format, submittal portal, or set of forms, tell us at the preconstruction meeting and we will produce it that way. Rework at closeout is expensive for the general contractor and completely avoidable.
Callbacks get a direct answer. If something we installed fails, we come back and look at it rather than routing the general contractor through a process that consumes more of your time than the repair itself. Warranty terms are confirmed in writing for each contract.
When Does Utility Work Belong on the Site Schedule?
Utility work belongs at specific points in the site sequence, and each point has a cost if it slips. Conduit routes should be staked once rough grading is done, crossings under future drive lanes should be bored before base and paving, and structures should be set to finished grade before curbs and sidewalks are formed.
We ask for the site schedule at preconstruction and mark those points on it. If the schedule moves, we move with it, but the order does not change: boring under fresh asphalt or resetting a handhole after the sidewalk is poured costs more than holding the right sequence.
| Site stage | Utility work that belongs here | Risk if it slips |
|---|---|---|
| Rough grading complete | Conduit routes staked and handhole locations set | Routes conflict with foundations or storm structures |
| Before base and paving | Bores under future drive lanes and sleeves placed | Cutting new pavement or boring under fresh asphalt |
| Before curbs and sidewalks | Conduit and handholes set to finished grade | Structures reset after concrete is placed |
| Before landscaping and irrigation | Pit restoration and final grade around structures | Damage to new sod and irrigation |
| Before owner acceptance | As-builts, photographs, and owner forms | Acceptance and retainage held |
How Are Scope Gaps Avoided on a Utility Subcontract?
Most disputes between a general contractor and a utility subcontractor come from items nobody assigned. The bore pit that sits in city right of way needs its own permit. The irrigation and site lighting lines installed by another trade are not marked by Sunshine 811, because member utilities mark only the facilities they own. The pull string, the handhole lids, and the restoration of a neighbor's yard all need an owner.
We go through those items at preconstruction and put them in writing. A one page scope split costs an hour and removes the argument that otherwise happens on the morning a crew arrives and finds the item was never covered by anyone.
Key takeaways
- On a general contractor's site, utility work becomes critical only when it slides into another trade's window, so the subcontractor's job is to hold the window it committed to.
- Bores under future drive lanes belong before base and paving, because boring under or cutting fresh pavement later costs more and looks worse.
- Sunshine 811 member utilities mark only their own facilities, so private site lines often need a separate private locate.
- Closeout documents collected during construction are ready when the job closes, which keeps retainage from waiting on paperwork.
Key terms
- Schedule interlock
- A dependency between two trades where one cannot start until the other finishes a defined step, such as conduit placement before sidewalk forming. Interlocks are where subcontractor delays turn into project delays, so they are identified at preconstruction and tracked at the weekly schedule meeting.
- Retainage
- A portion of each progress payment withheld by the owner or general contractor until the work is complete and accepted. Florida law limits how much retainage may be held on many projects, and missing closeout documents are a common reason its release is delayed.
- Sleeve
- A short length of conduit placed under a future pavement, sidewalk, or structure so cable or pipe can be installed later without cutting the finished surface. Sleeves are cheap to place before paving and expensive to replace with a bore afterward, so their locations should be marked and recorded.
- Private locate
- A utility locate performed by a private locating service for lines that Sunshine 811 member utilities do not own, such as site lighting, irrigation, and private water or power on a property. It fills the gap between the public locate ticket and what is actually buried on site.
| Scope item | Often assigned to | Why it matters |
|---|---|---|
| Right of way permits off site | Utility subcontractor or GC, named in the subcontract | Pits outside the property need their own permit |
| Maintenance of traffic | Utility subcontractor for its own work | Lane closures must match the approved plan |
| Private utility locates | GC, with subcontractor input | Sunshine 811 does not mark private site lines |
| Conduit proving and pull string | Utility subcontractor | Shows the conduit is clear before the cable crew arrives |
| Restoration of disturbed areas | Utility subcontractor | Keeps restoration off the punch list |
| As-builts and closeout forms | Utility subcontractor, in the GC's format | Supports owner acceptance and retainage release |
What this means for your project
For a superintendent, the risk from a utility subcontractor is mostly schedule risk carried into other trades. Committing to defined windows around grading, paving, and concrete, and reporting a threat to those windows early, lets you resequence before a crew stands idle. Owned equipment is what makes those commitments dependable.
Site risk is the second exposure. A strike on an active site stops several trades and generates an incident report, so locates, private locates where needed, and potholing near existing lines are worth the hours they take. Fluid containment and daily cleanup protect finished work and keep the owner's walkthrough uneventful.
Closeout risk is the one that costs money after the work is done. Assign as-builts, photographs, and owner forms in the subcontract, specify the format at preconstruction, and expect them at completion. When the paperwork is ready with the work, retainage moves on the project schedule rather than the paperwork schedule.

Frequently Asked Questions
- Can you hold a specific window between grading and paving?
- Yes, when the window is defined in advance. We plan mobilization around the trades directly before and after us and commit to a window we can hold with owned equipment and our own crew. If a permit, locate, or field condition threatens that window, you hear it while there is still time to resequence rather than after the paving crew is scheduled.
- How do you avoid damaging existing utilities on an active site?
- Locates are called and verified even on previously disturbed ground, and we pothole where the design puts the bore near an existing line. Bore paths are planned around known conflicts before the rig sets up. On a live site, a strike stops more than our work, so verification happens before drilling rather than after a change in ground feel.
- Do you restore the site or does that fall to us?
- We restore what we disturb to the site specification, including sod, pavement, curb, sidewalk, driveway aprons, and irrigation lines we cut. That includes bore and receiving pits located off site or in adjacent right of way. Restoration is scheduled as part of the work so it does not reappear on the punch list.
- What closeout documentation do you provide?
- As-built drawings of installed conduit and cable, photographs of work before backfill, conduit and duct assignments, and any owner or engineer forms required for acceptance. Tell us the required format at the preconstruction meeting and we will produce it that way, since closeout rework is a common cause of delayed retainage.
- Will Sunshine 811 locate everything on our job site?
- No. Sunshine 811 notifies member utilities, and they mark the facilities they own, usually up to the service point. Private lines installed on the site, such as site lighting feeds, irrigation, private water, and temporary power, are typically not marked. We review the site utility plan with your superintendent and recommend a private locate wherever those lines sit near our work.
- Who pulls the right of way permit when the bore leaves our site?
- That is agreed in the subcontract, and either arrangement works. When a bore or a pit extends into city, county, or state right of way, a separate permit from that authority is usually required. We can prepare and submit the application, or support your permitting team with plans and details. What matters is naming the responsible party before the schedule depends on it.
- Can you bore across areas where other trades are still working?
- Yes, with planning. The rig footprint, fluid handling area, and pipe staging are agreed with the superintendent before mobilization, and work areas are coordinated at the schedule meeting. A bore crosses active areas without opening a trench across another trade's path, and spoils and drilling fluid are contained so deliveries and adjacent work keep moving while we drill.
