# The Full Fiber Construction Project Process

TLDR

Fiber projects move through walkout, **permits and make-ready**, construction, splicing and testing, restoration, and **as-built closeout**. Approvals and material lead time drive the **schedule**, not drilling speed.

A fiber construction project runs in stages: scope walkout, design and permit coordination, make-ready or locates, mobilization, physical construction, splicing and testing, surface restoration, as-built documentation, and closeout. The construction itself is rarely the long pole. Approvals, make-ready, and material lead times decide the schedule, so they are tracked as milestones of their own.

## What does a fiber construction project include end to end?

A fiber build is a sequence of dependencies wrapped around a relatively small amount of physical work. Placing conduit, pulling cable, and splicing are the visible activities, but they sit at the end of a chain of approvals, verifications, and material decisions that determine whether they can happen at all.

That is why experienced owners judge a contractor on the parts nobody photographs. Locate management, permit tracking, material verification, daily reporting, restoration quality, and the documentation package are what separate a route that closes out on schedule from one that spends months in punch list.

The stages below apply to an underground route, an aerial route, or a mixed route. The order rarely changes. What changes is which stage holds the critical path on a given project, and that should be identified in the first week rather than discovered in the third month.

## Stage one: what does the scope review and field walkout catch?

The walkout is where a design meets the ground. A crew walks or drives the route with the drawings and records what does not match: poles that are not where records place them, driveways added since the survey, utility markings that suggest congestion, tree canopy, access constraints, and staging options.

The output is a constructability list. Every exception gets an option and a cost, so the owner can decide before mobilization instead of getting a change order during construction. The cheapest time to move a bore, relocate a handhole, or reroute a span is while it is still a line on a drawing.

The walkout also produces the practical inputs nobody thinks about until they are missing: where equipment can stage, which segments require night work, where residential notification is needed, and which property owners have to be contacted before a crew appears in their yard.

## Stage two: how are design coordination and permits handled?

Permits are jurisdiction specific and each one has its own review clock. A single route can cross city, county, and state right of way within a few blocks, and each authority has its own submittal package, fee schedule, traffic control expectations, and restoration standard.

Specialty crossings sit outside that normal path and take longer. Railroad crossings, water management district permits, wetland and environmental review, canal and drainage crossings, and private easements each carry their own process, and none of them accelerate because a construction schedule is tight.

The practical strategy is parallel submission with tracked dates. Submit everything that can be submitted in week one, log the review status weekly, and sequence construction so the first segments to be built are the ones with approvals already in hand.

## Stage three: how do locates, potholing, and make-ready reduce risk?

Underground work begins with a locate ticket through Florida's one call system, which requires advance notice before excavation and produces responses from each member utility. Tickets expire, so they are managed as live documents on a production schedule rather than called once at the start of a project.

Marks alone are not verification. Where a bore crosses an existing utility with limited separation, or where responses conflict, vacuum potholing exposes the utility and establishes its actual depth and position. Potholing is inexpensive compared with a strike, and it is the single highest value risk reduction step in underground construction.

The aerial equivalent is make-ready, which runs on the pole owner's timeline and depends on other attaching companies performing their own transfers. Both paths share the same lesson: the work that determines the schedule happens before any production equipment reaches the site.

## Stage four: what happens at mobilization and material verification?

Mobilization is more than moving equipment. Material is verified against the submittals first: cable type, fiber count and coating, conduit size and color, handhole and vault ratings, and the hardware that has to match the pole owner standard. Discovering the wrong conduit color after two thousand feet is placed is an expensive lesson.

Reels get inspected and tested before installation. An OTDR shot on the reel confirms the fiber is intact after shipping and gives a starting point, because glass damaged in transit is far cheaper to find on the truck than after it is in the ground and spliced at both ends.

The site work of mobilization includes staging, traffic control setup, a safety briefing tied to the specific hazards of that route, and notification to residents and businesses. Notification is not a courtesy item. It is what prevents daily interruptions that cost more production time than the notification would have.

## Stage five: how is underground and aerial construction carried out?

Underground production means boring or trenching, placing conduit with tracer wire, and setting handholes and vaults to finished grade. Conduit is then proofed with a mandrel or rodder pass before any cable goes in, because a partially collapsed duct discovered during a blow is a much larger problem than one discovered during proofing.

Cable placement is either blown or pulled. Blowing carries the cable on airflow, imposing little tension and suiting long continuous runs in clean conduit. Pulling is appropriate for shorter runs, congested paths, and situations where a blowing setup cannot be staged. Both respect the same published tension and bend radius limits.

Aerial production is strand placement, tensioning to the sag chart, and lashing. Real production rates on either path track congestion, access, and approvals far more closely than they track equipment capability, which is why a realistic schedule is built from the route conditions rather than from an equipment brochure.

## Stage six: how are splicing, testing, and acceptance handled?

Splicing works from a matrix prepared in advance that assigns every buffer tube and fiber. Working from an assumption instead of a matrix produces crossed fibers that pass every loss test and still leave circuits down.

Testing is bidirectional OTDR at both single mode wavelengths, plus end to end insertion loss against the design budget. Anything out of specification is corrected before the closure is sealed and the slack is stored, because reopening a sealed closure to fix a known bad splice costs several times what fixing it in the moment costs.

Acceptance should be defined numerically in the contract. Maximum individual splice loss, project average, span loss limits, required wavelengths, and required trace format all belong in the scope, so acceptance is a measurement rather than an opinion.

## Stage seven: what do restoration and site cleanup require?

Restoration is where a technically sound project earns or loses its reputation. Sod, asphalt, concrete, driveway aprons, sidewalks, irrigation, landscaping, and pavement markings are all restored to the standard the permit specifies, not to whatever the crew finds convenient.

Irrigation deserves particular attention in Florida. Sprinkler lines sit shallow in nearly every developed corridor, they are almost never locatable, and a broken line that is repaired the same day is a non-event while one that surfaces a week later becomes a complaint to the municipality.

Restoration punch items are the most common cause of delayed final acceptance on otherwise clean projects. Treating restoration as part of production, closing it out behind the crew rather than in a separate pass months later, removes that risk almost entirely.

## Stage eight: what goes into the as-builts and documentation?

Field redlines are captured daily during construction and become the final as-built at the end. Reconstructing a route from memory at closeout produces a document that looks complete and misleads the next crew that relies on it.

This package has a long service life. It is what a future contractor designs against, what a locator works from, what a restoration crew uses at two in the morning, and what establishes facility position if a third party damages the plant later.

- Route alignment with stationing or GPS points tied to fixed features
- Depth of cover at every crossing named in a permit, with the bore log
- Handhole, vault, and pedestal locations with size and rating
- Splice locations, splice matrices, and stored slack quantity and location
- Conduit occupancy, spare duct count, and tracer wire routing
- Pole attachment record with heights, strand size, and span lengths
- Test results, permit numbers, and inspection sign-offs

## Stage nine: how do closeout and the punch list work?

Closeout starts with a walk performed with the owner or engineer, producing a punch list with an assigned date for each item. A punch list without dates is a backlog, and backlogs are what keep projects open long after the last splice is finished.

Permit closure runs alongside it. Each authority has a final inspection and a restoration sign-off, and unresolved permits can block future work in that jurisdiction long after this project is forgotten. They are tracked to closure like any other deliverable.

Final payment usually depends on the documentation package being complete and accepted. That is the practical reason documentation is treated as a deliverable with a due date rather than as paperwork that happens after the work. It is the last item on the critical path.

## What actually drives the schedule?

Owners consistently overestimate how much of a schedule is production and underestimate how much is approval. On most routes, the physical placement is a smaller share of the calendar than the approvals and dependencies that precede it.

The comparison below shows where the time actually goes on each path. The useful conclusion is that an underground route and an aerial route are slow for entirely different reasons, so a mixed route needs both clocks started on day one.

| Project stage | Underground route | Aerial route |
| --- | --- | --- |
| Approval path | Right of way permits, traffic control, and locate tickets | Pole attachment application and make-ready |
| Longest wait | Permit review and utility locate quality | Make-ready construction and existing attacher transfers |
| Weather sensitivity | High, saturated ground and flooded pits | Moderate, wind and lightning stop bucket work |
| Restoration burden | High, pavement, sod, and driveways | Low, limited to pole sites and access points |
| Change flexibility | Low once conduit is in the ground | Higher, spans can be re-lashed with owner approval |
| Long term exposure | Third party dig-ins | Wind, vehicle strikes, and tree contact |

## How should a scope be written so bids are comparable?

Most bid spreads that look like large price differences are actually scope differences. One bidder included restoration to the permit standard and traffic control, another assumed the owner handled both. Comparing those numbers side by side tells you nothing useful about either contractor.

Strilla Communications Company works from the same five steps on every project: locate and plan, mobilize, execute, document, and close out. Owned equipment and in-house crews cover both underground and aerial scope, a single point of contact handles daily communication, and the documentation package is delivered as part of the work rather than chased afterward.

Strilla Communications Company was formed in January 2020 and works from New Smyrna Beach, with Volusia County as the primary service area, regular work across Central Florida, and statewide capability on larger programs. Call (386) 396-2033 or email hello@strillacommunications.com to review a route or a bid package.

- State quantities on a clear basis: bore footage, aerial footage, splice count by fiber, and structure count
- Name who obtains permits, who pays fees, and who provides traffic control
- Define the restoration standard by surface type rather than using the word restore
- Specify test requirements: wavelengths, both directions, thresholds, and trace format
- Specify the documentation deliverable, its format, and its due date
- State the material supply split and who owns overage and salvage
- Define standby and delay terms, because permits and make-ready will move

## Key takeaways

- On most fiber routes, approvals, make-ready, and material lead times take more calendar time than physical construction does.
- Every exception found at the field walkout should get an option and a cost before mobilization, because a line on a drawing is the cheapest thing to move.
- Vacuum potholing at tight utility crossings is the highest value risk reduction step in underground fiber construction.
- Acceptance should be written into the contract as numbers: maximum splice loss, project average, wavelengths, test direction, and trace format.
- Restoration punch items and incomplete documentation are the most common reasons an otherwise clean fiber project waits for final acceptance.

## Key terms

**Field walkout**: A field walkout is a pre-construction survey of the route with the design drawings in hand. The crew records mismatches such as moved poles, new driveways, congested utility corridors, tree canopy, and access limits, then produces a constructability list with options and costs before mobilization.

**Redline**: A redline is a field markup of the design drawings made during construction to show where the built route differs from the design. Captured daily, redlines become the source for the final as-built drawing that future crews, locators, and engineers rely on.

**As-built**: An as-built is the final record drawing of a completed fiber route. It shows alignment, depth of cover at permitted crossings, structure locations, splice points, slack storage, conduit occupancy, and pole attachments, along with test results and permit references. It is used for locates, design, and repair for years after closeout.

**Conduit proofing**: Conduit proofing is running a mandrel or duct rodder through newly placed conduit to confirm it is continuous, open, and not crushed or deformed before cable goes in. The results belong in the closeout package as evidence that the duct is usable for the cable it was built to carry.

**Punch list**: A punch list is the record of incomplete or deficient items found during the closeout walk with the owner or engineer, such as restoration repairs, missing labels, or documentation gaps. Each item needs an assigned completion date, because final acceptance and payment usually wait on the list being cleared.

*Fiber project stages, what each produces, and the risk it removes*

| Stage | Main output | Risk it removes |
| --- | --- | --- |
| Scope review and walkout | Constructability list with options and costs | Change orders discovered during construction |
| Design coordination and permits | Approved permits with tracked review dates | Crews ready with no released segments |
| Locates, potholing, make-ready | Verified utility positions and released poles | Utility strikes and stalled aerial work |
| Mobilization and material check | Material matched to submittals, reels tested | Wrong conduit or damaged glass placed in the ground |
| Construction | Proofed conduit, placed cable, set structures | Collapsed duct found during cable placement |
| Splicing and testing | Splice matrix and bidirectional OTDR results | Crossed fibers and out of specification splices |
| Restoration | Surfaces restored to the permit standard | Complaints and delayed permit closure |
| As-builts and closeout | Accepted documentation package and cleared punch list | Open permits and withheld final payment |

## What this means for your project

Start every approval clock in the first week. Permits, locate tickets, pole attachment applications, and long lead material orders should run in parallel, with construction sequenced to follow whichever segments are released first. Put schedule contingency on approvals and unknown utilities, not on production rates.

Most bid spreads are scope differences, not price differences. Specify quantities, permit and traffic control responsibility, the restoration standard by surface type, test requirements, documentation format and due date, and delay terms, so the prices you compare cover the same work.

Make the documentation package a dated deliverable tied to final payment, and close restoration behind the crew. Those two choices remove the most common reasons a finished route stays open for months in punch list.

## Frequently Asked Questions

**How long does a fiber project take from award to closeout?**: It depends far more on approvals than on production. Permits, locate quality, and make-ready normally consume a larger share of the calendar than placement does. The way to compress a schedule is to submit approvals in parallel during week one and sequence construction to follow whichever segments get released first.

**Who is responsible for pulling permits?**: It should be stated explicitly in the contract because assumptions here create real disputes. Commonly the contractor obtains right of way and traffic control permits and manages locate tickets, while the owner or its engineer handles design approvals and the pole attachment application. Fees, bonds, and inspection coordination are assigned the same way.

**What is the difference between a redline and an as-built?**: A redline is the field markup produced during construction showing what changed from the design. The as-built is the final drawing that incorporates every redline into a clean record. Redlines captured daily produce an accurate as-built. Redlines reconstructed at the end of a project produce a document that reads well and misleads later crews.

**When should splicing be scheduled?**: After placement is complete and the cable has been accepted, but not so late that testing becomes the last item on the critical path. Sequencing splicing by completed segment lets test results come back while other segments are still being placed, which leaves time to correct anything out of specification before closeout.

**What usually delays final acceptance?**: Restoration punch items lead the list, followed by incomplete documentation, test results that were never corrected, and open permits awaiting final inspection. All four are avoidable. Closing restoration behind the crew, capturing redlines daily, and fixing out of specification splices before sealing closures removes most of the typical closeout backlog.

**Can one contractor handle both aerial and underground scope?**: Yes, and on a mixed route it removes a coordination boundary that otherwise causes schedule gaps. When the same organization places the bore, sets the structures, builds the aerial spans, and splices the route, there is no negotiation over who owns a transition point and no waiting for a second mobilization to close a segment.

**Where should schedule contingency be placed?**: On approvals and unknown existing utilities, not on production rates. Drilling and lashing speeds are reasonably predictable. Permit review cycles, make-ready transfer queues, locate response quality, and what is actually found at potholing are not, and those are the items that historically move completion dates on fiber routes.
