Outside Plant Construction

What Does Outside Plant Construction Include?

Outside plant construction covers every physical layer of a network that lives outside a building: bore paths, conduit, handholes and vaults, aerial strand, the cable itself, the splices that join it, and the restoration that puts the ground back the way you found it. On a turnkey OSP project, one contractor owns all of that scope, so the interfaces between trades stop being your problem to manage.

Strilla Communications self-performs underground and aerial work with owned equipment and in-house crews. That matters on OSP because the schedule risk in these builds is rarely a single hard bore. It is the gap between the drill crew finishing and the splice crew arriving, or the week lost waiting on a third party to restore a right of way before the county will sign off on the permit.

A typical OSP scope for us includes directional drilling, conduit and duct placement, handhole and vault setting, aerial strand and lash, fiber placement by pulling or blowing, fusion splicing and testing, tracer wire and locate-ready construction, restoration, and the as-built package that closes the job out.

Scope is defined by what the network actually needs, not by a fixed package. Some clients hand us a permitted design and a material list. Others bring a route concept and need constructability input before anything goes to permit. Either way, the work is priced by scope line, so you can see what each portion of the build costs and compare it against separate awards.

• Underground: directional bores, open cut where allowed, conduit, tracer wire, handholes and vaults
• Aerial: strand installation, lashing, overlash, and cable placement on existing pole lines
• Cable: pulling and jetting into new or existing duct, plus mid-span access where design calls for it
• Splice and test: fusion splicing, enclosure installation, and end-to-end optical testing
• Restoration: sod, asphalt, concrete, and landscaping returned to the standard the permit requires
• Documentation: daily production reports, GPS as-builts, photo logs, and test records

Backbone or Distribution: Which Part of the Build Are You Awarding?

Backbone and distribution are built differently, and the difference drives crew mix, production rate, and risk. Backbone is the long-haul path between headends, huts, cabinets, and aggregation points: fewer runs, longer bores, larger duct counts, higher fiber counts, and crossings of arterials, state right of way, rail, and water. Failure on a backbone segment is expensive because everything downstream of it waits.

Distribution is the branch network inside a serving area. It is high volume and repetitive: many short bores down easements and rear lots, driveway and sidewalk crossings, handholes near lot lines, terminals, and drop-ready splice points. No single unit is difficult, but a distribution build lives or dies on daily production counts, restoration quality, and how well the crew handles residents and property owners.

Most builds need both, and the order matters. Backbone that lands late strands distribution crews with nowhere to splice into. Distribution that runs ahead of permitting leaves open handholes and unrestored yards sitting in a neighborhood for weeks. We plan the two tracks together so the splice-ready dates line up with the cable delivery and the turn-up sequence.

Aerial or Underground: How Is the Placement Method Chosen?

The route usually sets the placement method, not preference. Aerial construction makes sense where a usable pole line already exists, make-ready is manageable, and the pole owner will approve the attachment. Make-ready is the work that prepares a pole for a new cable, such as moving existing lines or replacing the pole. Underground makes sense where there are no poles, where the owner wants the cable protected from wind and vehicle strikes, or where a city or development requires buried utilities.

Each method puts risk in a different place. Aerial work depends on pole owner approvals and on make-ready performed by other attachers, which no contractor controls. Underground work depends on locates, soil, and crossing permits, and it carries restoration cost that aerial work mostly avoids. In Florida, storm exposure is part of the decision: buried plant avoids wind and falling limbs, while aerial plant is often quicker to repair once crews can reach it.

Many routes end up mixed. A segment can run aerial along an existing pole line, drop down a riser into buried conduit to cross a highway or enter a subdivision with underground utilities, and come back up on the other side. Because we self-perform both, that transition is a detail on one schedule rather than a handoff between two vendors who each think the riser belongs to the other.

• Existing pole line with room for a new attachment: aerial is often the faster path once make-ready is complete
• No poles, or a development that requires buried utilities: underground conduit and handholes
• Highway, rail line, or waterway in the way: a directional bore, even on a mostly aerial route
• Owner priority on storm hardening: underground, with structures kept out of low spots that hold water

How OSP Projects Get Phased

We break an OSP build into releasable phases rather than treating it as one long push. A phase is a segment of route that can be permitted, built, spliced, restored, and closed out on its own. Phasing this way means you get finished, documented, invoiceable work early instead of waiting until the last splice on the last segment before anything is complete.

Phase boundaries are usually set by permit authority, cable reel length, splice point location, and make-ready readiness. A county road segment with an approved permit and cleared locates becomes its own phase. A subdivision waiting on pole make-ready becomes a later phase, so the crew is not idling in front of an attachment that is not ready.

Each phase carries a short gate: placement complete, cable in, splice and test complete, restoration complete, documentation submitted. We report status against those gates daily so you always know what is buildable now, what is blocked, and what is waiting on someone outside our scope. Blocked work gets flagged the day it is discovered, not at the end of the week.

• Permit-driven phasing so no crew is working ahead of an approval
• Make-ready status tracked separately so aerial phases release when the poles are actually clear
• Splice points and reel lengths used as natural phase boundaries
• Restoration closed inside the phase, not deferred to a punch list at the end of the job

How Do You Coordinate Multiple Crews on One Build?

You get a single point of contact who owns the whole build, not one contact per crew type. That person holds the schedule, the permit status, the locate tickets, and the daily report, and they are the one you call when a design change or a field conflict shows up. Internally, the drill crews, aerial crews, splice crews, and restoration crews work off the same phase plan.

Running underground and aerial in-house removes the most common OSP coordination failure: two vendors each waiting on the other. When a route has to transition from buried conduit to a riser and aerial strand, the same schedule owner sequences both sides. When a bore hits an unmarked utility, the change is priced and rescheduled without renegotiating three separate contracts.

Crews are staged to keep sequence tight rather than to maximize how many are on site at once. Drilling and conduit lead, structures and cable follow, splice crews come in behind on completed segments, and restoration follows close enough that a neighborhood is not left torn up. Adding crews only helps when the work in front of them is permitted, located, and cleared.

Field changes are handled the same way. When a bore hits an unmarked utility, a pole comes back unusable, or a property owner refuses access on the day of work, the change is documented, priced if it affects scope, and reflected in the next daily report. You should never learn about a two week deviation from an invoice at the end of the month.

Permitting, Make-Ready, and Florida Ground Conditions

Most OSP delay in Florida happens before a rig ever spools rod. Permits move through different authorities depending on the route: state right of way, county public works, city engineering, and private easements each have their own submittal package, review cycle, and restoration standard. We support the permit package with route drawings, bore profiles, and the crossing details reviewers ask for, and we build to the conditions the approval actually carries.

Aerial segments add make-ready. Pole owners and existing attachers set their own timelines, and a build plan that assumes attachment on request will slip. We track make-ready status per pole line and sequence aerial phases behind it so aerial crews are dispatched to work that is genuinely ready.

Ground conditions in Florida change quickly across a single route. Sugar sand, hardpan, coquina, clay lenses, and high water table can all appear inside a few hundred feet, and coastal corridors carry dense congestion of existing utilities. That changes drilling fluid mix, reaming approach, pullback planning, and how much potholing a segment needs. We plan bore paths with those conditions in mind rather than discovering them at rod ten.

What Drives the Cost of an Outside Plant Build?

Footage is the starting point, but it rarely explains why two routes of similar length price so differently. Cost on an OSP build follows how the footage is placed and what it passes through: the share that has to be bored, the number and type of crossings, the ground conditions, the restoration surface, the traffic control a permit requires, and the count of structures and splice points.

Underground cost climbs with crossings, hard layers in the soil, congested corridors that need potholing, and premium restoration such as stamped concrete, pavers, or arterial pavement patches. Aerial cost climbs with make-ready, pole replacements charged by the pole owner, guying and anchoring, and spans that need a bucket truck working inside a lane closure. Splicing cost follows fiber count and the number of splice points on the route.

Soft costs belong in the conversation too. Permit fees, pole attachment fees, inspection fees, and engineering are often carried by the owner, and a bid should say so plainly so nothing falls between the two parties. We price by scope line and state the assumption behind each line. When a field condition changes, the change maps to a specific item instead of turning into a dispute over a lump sum.

• Placement mix: bored footage, open cut where allowed, and aerial footage priced separately
• Crossings priced by type: arterial, state highway, railroad, waterway, driveway, and sidewalk
• Restoration priced by surface: sod, asphalt, concrete, pavers, and irrigation repair
• Owner-carried items named in the bid: permit and attachment fees, make-ready charges, and material supply

What Does the Closeout Package Look Like?

Documentation is a deliverable on our OSP builds, not an afterthought. Closeout is where a lot of turnkey projects fall apart, because the field work is done but the owner cannot get the as-builts, test results, and photos needed to close a permit, release retainage, or hand the network to operations.

We collect documentation as the work happens: daily production with locations and quantities, GPS points on structures and route, depth and crossing records, splice and enclosure details, optical test results, and before and after restoration photos. Because it is captured in the field, the package does not depend on someone reconstructing the build from memory weeks later.

You get a per-phase submittal so closeout accumulates through the project instead of landing as one large package at the end. If your GIS team, your permit authority, and your operations group all need different formats, we set that up at kickoff rather than reformatting everything after the fact.

If a route we built later needs maintenance or emergency repair, that same documentation is what makes the response fast. A crew that already has accurate as-builts, splice records, and depth data is troubleshooting a fault instead of rediscovering the network under a road.

• GPS as-built data for bore paths, conduit, handholes, vaults, and aerial route
• Splice records, enclosure locations, fiber assignments, and optical test results
• Depth and crossing verification records for permitted crossings
• Restoration photo documentation, before and after, per work location
• Daily production reports with quantities tied to the phase and pay item structure

Who Hires Strilla for Turnkey OSP Work

ISPs and broadband expansion teams are a natural fit when they need a build partner who can take a route from permit support through turn-up support without stitching together three subcontractors. Owned equipment and crews mean the schedule commitment we give you is a commitment we control, not one we pass through to somebody else.

General contractors can hand us the communications scope on larger site and roadway work, where the fiber portion has to fit inside a much bigger schedule and a much stricter site standard. Municipalities, county public works departments, and city engineering groups can award institutional networks, traffic and signal fiber routes, and connections between public facilities the same way, where restoration standards and public visibility are as important as the bore itself.

OSP engineers and construction coordinators generally care about two things: whether the field matches the design, and whether they will get the records they need. Where field conditions force a design deviation, we flag it, propose the alternative, and document what was actually built so the as-built and the design do not drift apart.

Where We Build in Florida

Volusia County is our home service area, covering New Smyrna Beach, Daytona Beach, Deltona, Ormond Beach, Edgewater, Port Orange, DeLand, and the surrounding communities. That local familiarity shows up in knowing the permitting process, soil expectations, and which corridors carry heavy utility congestion.

Central Florida is our secondary service area, including Orange, Seminole, Osceola, Lake, and Polk counties, and we take statewide Florida work for larger builds and program-level assignments. For projects outside our home region we plan mobilization, staging, and crew logistics into the phase schedule up front so travel does not quietly become a delay.

We also stay available for emergency restoration on networks in our service area. If a build we placed takes damage from a storm, a dig-in, or a vehicle strike, you are calling a contractor who already has the as-builts for that route.

Mobilization on a new project usually starts with a site visit rather than a phone quote. Route conditions, access, and existing utility congestion tell us more in an hour on the ground than a set of drawings does, and that visit is also where scope boundaries and reporting expectations get set.
