Fiber Route Engineering Services
Draftech compares realistic route alternatives for your planned fiber build and delivers a feasibility report with a recommended route. Our in-house engineers put cost per passing and permit exposure behind the decision before you commit to HLD.
Put a documented comparison behind your route decision
Draftech's fiber route engineering services give ISPs, carriers, electric cooperatives and BEAD subgrantees a documented basis for choosing which route to build within a service area you have already identified. You receive mapped alternative corridors, a cost-per-passing comparison, aerial-versus-underground assumptions, permit-exposure flags and a recommended route. One accountable team develops the alternatives and explains the recommendation, so your budget discussion and engineering handoff use the same assumptions.
The engagement starts after you identify a candidate service area or access corridor, before you purchase high-level design (HLD). It provides the route decision that feeds our fiber network design services. Your team can assess the alternatives before authorizing design spend, committing capital or carrying a route into a grant application.
Intercity, backbone and dark fiber routes belong to our long-haul fiber engineering services, and regional middle-mile routes to our middle-mile fiber engineering services.
A first sketch can become the default simply because nobody priced another option. Once HLD begins, the team finds the route needs more underground footage than budgeted, rail or waterway crossings outside the estimate, or right-of-way the plan never accounted for. Engineering pauses for a reroute while management continues to rely on a business case built around the original line. Draftech prices and risk-rates the alternative corridors before you purchase HLD. At this stage, switching corridors costs a revised plan, not a stalled HLD and a reroute.
What our fiber route engineering services deliver before HLD
As the first step of OSP route design services, this engagement produces a feasibility package focused on selecting a route. Each alternative has a clear name that carries through its map, cost comparison and risk assessment. Reviewers can connect a recommendation to the corridor it describes without interpreting separate spreadsheets and sketches.
The package includes:
- Mapped route alternatives: Realistic corridors for the planned build, developed from existing records and public sources.
- Cost-per-passing comparison: Planning estimates for the alternatives, with the cost basis and passing counts stated so differences are visible.
- Aerial-versus-underground mix: The assumed placement mix for each alternative and its effect on the comparison.
- Permit-exposure flags: Rail, state DOT, waterway and other crossing or occupancy issues that could put an alternative into additional review queues.
- Feasibility report and recommendation: Scored alternatives, the reasons for the recommended route and the assumptions that remain open when you hand the baseline to HLD.
The report gives your decision-makers the rationale behind the preferred option. It also shows why each lower-ranked corridor lost on cost per passing or permit exposure.
Compare the economics of the actual alternatives
Cost per passing connects a corridor decision to the access build's business case. A lower total route estimate can be misleading if that alternative reaches fewer of the intended locations. Equally, an apparently economical corridor can depend on aerial segments that records indicate may need make-ready or pole replacement, or poles with no apparent attachment space.
Draftech states the assumed passings and cost scope for each option. Where alternatives serve different portions of the proposed area, we make the difference explicit. Your team can see whether an apparent advantage comes from the route itself or from a change in what the project would serve.
The aerial-versus-underground mix is part of that comparison. We use the available pole and conduit records to establish planning assumptions for each corridor, then show how those assumptions affect estimated cost per passing. Where records show unknown or full conduit occupancy, we flag that risk against the alternative's cost assumptions and ranking.
We identify assumptions that could materially change the ranking. If a preferred option depends on an uncertain aerial segment or an unresolved right-of-way question, the report explains that dependency alongside its estimated advantage. Management can decide whether to carry the route forward with that condition or favor an alternative with different exposure.
See permit exposure before it enters the budget
A route's crossing burden belongs beside its economics. Similar cost-per-passing estimates can conceal very different permitting dependencies. Draftech flags the exposure for each alternative, giving you a way to assess which approvals could affect the route decision before a preferred corridor becomes a budget commitment.
The comparison identifies:
- Rail crossings that would require subsequent railroad crossing permit work.
- State DOT crossings or occupancy that would enter DOT and highway right-of-way permitting.
- Waterway and utility-corridor crossings that would require crossing and encroachment permit coordination.
- Other right-of-way and easement exposure evident in the available records.
These flags identify permit exposure and do not stand in for approval. Where a crossing may require environmental review, that dependency stays visible in the recommendation.
For your board memo or capital request, the feasibility report lists unresolved occupancy alongside the affected alternative and its estimated cost per passing.
How the desktop study runs
We begin with your identified project area, intended passings, candidate corridors and the decision you need to make. A planned last-mile extension may call for a focused comparison around one access constraint. A cooperative or BEAD project area may have several meaningful corridor choices affecting the overall investment. The scope follows those choices.
Our engineers review your existing GIS, pole and conduit records, publicly available or client-supplied aerial imagery, and parcel and right-of-way data. We develop alternatives from those inputs, compare their economics and permit exposure, and score them against the project's priorities. The engagement concludes with a feasibility report and route recommendation for your review.
This work is desktop-based. Field verification and permit approval are not part of this stage. Where a missing record affects a cost assumption or the recommendation, we identify the limitation and its consequence for the route choice. That lets you commission the next engineering phase with the unresolved questions already visible.
One team accountable for the recommendation
Draftech performs all engineering in-house. The same engineers build the maps, passing counts, placement assumptions and permit flags, so the numbers in the report agree with each other. A question about why a route ranked first returns to the team that developed the recommendation.
That accountability matters when different stakeholders favor different outcomes. Finance may prioritize cost per passing while the project team focuses on crossing exposure. The report puts those tradeoffs in one place and explains which ones drive the recommendation. It gives your internal planner a documented basis for the decision and gives management a clear record of the conditions it is accepting.
Subsequent fiber splice design begins after route selection, while independent fiber design review addresses completed design work. This engagement ends with the recommended route and the rationale for choosing it.
Fiber Route Engineering Services FAQ
When should we hire Draftech for route feasibility?
Engage us once you have identified the service area or corridor, while route selection is still open. Our ISP network feasibility and planning services give you a documented route comparison before you buy HLD or base a capital decision on an untested preferred route. We compare the alternatives and document the recommendation your decision requires.
Can you assess a route our internal planner already favors?
Yes, we can include your preferred corridor in the alternatives comparison. We assess it alongside other options for the planned build and explain how their economics and permit exposure differ. The outcome may support your planner's choice or show why another corridor deserves the investment.
Who on our team can use the feasibility report?
Your finance team, board and grant team can each review the recommended route from the same document. The mapped corridors, cost-per-passing comparison and permit-exposure flags give them a common basis for reviewing the recommendation and its open assumptions.
What happens after we choose the recommended route?
The selected route becomes your HLD baseline, with the open assumptions listed in the feasibility report. Your engineering team receives the mapped corridor, cost basis and permit-exposure flags behind the decision so it can carry those assumptions into the next scope.
What records do you need to compare route alternatives?
Send your identified service area, the locations you plan to pass (your target location list), existing GIS, available pole and conduit records, and any corridors already under consideration. Include known crossing or access constraints and the capital, board or grant decision the study will support. We use those inputs to define the comparison and identify missing information that could affect it.
Choose the route your business case can support
Bring Draftech the project area before the first corridor sketch becomes the only option in the budget. Our team will scope the alternatives comparison and deliver a feasibility report that explains the recommended route, its economics and its permit exposure. Contact our fiber engineering team to commission the study before HLD begins.
