Complete Project for Cirion — 421 Meters of Fiber Optic Cable Beneath Av. Tancredo Neves, from Permit to As-Built
When a critical infrastructure operator needs to connect one of Salvador’s largest commercial complexes on an accelerated timeline — without interrupting traffic on one of the Bahian capital’s busiest avenues — the choice of execution partner is decisive. Hype Telecom was engaged by Cirion (at the time, CenturyLink Comunicações do Brasil LTDA) to deliver the complete project — from design through as-built — of a 288-fiber underground network along Avenida Tancredo Neves, connecting to the Salvador Trade Center. The result: 421.36 meters of infrastructure built using a non-destructive method, within the contractual timeline, with all documentation fully regularized with municipal authorities.

The Challenge
Avenida Tancredo Neves is a high-density arterial roadway in Salvador. Any intervention in the roadbed requires authorization from TRANSALVADOR (Salvador’s municipal traffic authority), payment of specific public fees for arterial roadway works, executive project approval by the City government, and an ART (Anotação de Responsabilidade Técnica — a formal Technical Responsibility filing) registered with CREA-BA (the regional engineering licensing council). Beyond the regulatory complexity, the physical environment demanded heightened attention: the presence of other operators’ networks and underground public utilities along the route made the conventional destructive method unviable without unacceptable operational and reputational risk for Cirion.
There was also schedule pressure. The maximum timeline granted by TRANSALVADOR for execution of the work was 120 days — and market experience shows that projects with this level of regulatory density frequently consume that entire window just in approval procedures, leaving physical construction compressed and the client exposed.
Any network or operations manager who has overseen an underground infrastructure project in a Brazilian state capital knows the greatest risk isn’t in the physical execution. It’s in the municipal approval queue, incomplete documentation, an ART filed outside the required window, or an interference survey conducted without rigor — any of which can derail the boring plan on the very first day of work.
Why Hype Telecom
Hype Telecom was selected by Cirion for offering a value proposition that the local market rarely assembles under a single provider: the ability to prepare and file the executive design, manage the entire approval process with both the City of Salvador and TRANSALVADOR, mobilize a team for non-destructive execution, and deliver the as-built with complete documentation for final regularization of the work.
The contract (Contract 002-2020, executed on 02/03/2020) already defined turnkey scope, and Hype Telecom mobilized the responsible civil engineer (ART No. BA20200246929 — CREA-BA) and began topographic survey and executive design work immediately, without waiting for approval to start preparing for execution. When the permit arrived, the team was already ready.

Field Records — Data Book
- Complete executive design: topographic survey, route plan with underground vaults, boring plan, and descriptive report delivered before municipal approvals began.
- Full regulatory management: filing and follow-up with the City of Salvador (SEDUR/SUCOM Proc. 5,972/2020) and TRANSALVADOR (Proc. 2567-2020) through to the construction permit, including DAT and TPU fee payments.
- ART CREA-BA issued and settled: formal Technical Responsibility registered (ART No. BA20200246929) with a licensed civil engineer, prior to the start of physical execution.
- Interference survey via direct and indirect methods: mapping of existing underground networks along the route before finalizing boring plans, eliminating collision risk with existing infrastructure.
- Non-Destructive Method (MND): horizontal directional drilling with no cutting or breaking of the road surface on Av. Tancredo Neves — zero impact to the arterial roadway’s pavement.
- Night execution: arterial roadway crossing carried out at night, maintaining 100% of daytime traffic flow without interruption.
- Underground vaults built to design: construction and installation of access vaults with pavement restoration at access points, within required municipal standards.
- DD-288FO-TS cable installed and tested: 288 optical fibers in HDPE conduit, with post-installation tests recorded in a digital archive and delivered to Cirion.
- As-Built and Completion Certificate: design updated with actual executed positions and final regularization with the City of Salvador, including issuance of the Public Roadway Works Completion Certificate.
- Record timeline: work planned for completion in 67 days (per ART), against a maximum term of 120 days granted by TRANSALVADOR — 43.8% margin relative to the regulatory limit.
The Result for the Business
For Cirion, the immediate result was connectivity for the Salvador Trade Center within the timeline the business required. But the medium-term result was broader: a regularized underground infrastructure, fully documented and delivered with an updated as-built, with a Completion Certificate issued and all documentation archived — meaning any future intervention on the network can be planned against a reliable base of information.
The choice of the non-destructive method, beyond preserving the pavement of Av. Tancredo Neves, eliminated the risk of citation for damage to public roadway and avoided any reputational impact associated with trench excavation on a high-traffic avenue — a risk telecommunications operators cannot afford to ignore in high-traffic regions.
The 67-day execution timeline (per the ART), against the 120 days authorized, gave Cirion significant margin to commission services ahead of the dates committed to its end clients in the complex — the kind of buffer that, in a competitive market, makes a difference in contract retention.
What This Means for Network and Operations Managers
Every network manager who has overseen an underground fiber project in a Brazilian state capital knows the critical schedule risk is rarely in the physical execution. It comes earlier: in the quality of municipal filings, in an ART issued within the correct window, in command of the TRANSALVADOR system, and in the rigor of the interference survey — variables that, when poorly addressed, derail the boring plan within the first meter of work.
Hype Telecom’s practical differentiator in this type of project is vertical integration: the same company that prepares the design is the one that manages the approval, executes the work, and delivers the as-built. There is no handoff between designer and contractor. There is no disagreement over the correct alignment when boring encounters an unmapped interference. The decision is made by the same team that drew up the plan.
For organizations that need to expand underground infrastructure in regulated urban environments — whether in a Bahian state capital or any other market where public roadway access depends on municipal approval — this integration isn’t a comfort differentiator. It’s protection against schedule and regulatory risk.
Frequently Asked Questions
A complete turnkey project: executive design preparation, topographic survey, ART CREA-BA, filing and approval follow-up with the City of Salvador (SEDUR/SUCOM) and TRANSALVADOR, DAT and TPU fee payments, MND crossing execution on Av. Tancredo Neves (night operations), underground vault construction, pavement restoration, as-built, DD-288FO-TS cable installation, and post-installation testing.
Av. Tancredo Neves is classified as an arterial roadway by TRANSALVADOR, with high traffic volume and existing underground networks from multiple operators. The destructive method (trench excavation) would have required partial road closure, increased the risk of damage to existing infrastructure, and generated additional pavement restoration obligations. The MND (horizontal directional drilling) eliminated all of these risks and was executed entirely at night.
The contract was executed on 02/03/2020. The ART was registered on 02/05/2020. TRANSALVADOR's authorization was issued with a 120-day term for execution. Hype Telecom managed all filings and fee payments (TRANSALVADOR DAT, TPU, DAM) through to obtaining the construction permit, without generating any unexpected delay for Cirion.
The Data Book consolidates all project documentation: ART CREA-BA, executive design, construction permit, TRANSALVADOR authorization, payment receipts (DAT and TPU), boring plans, photographic records of every phase of the work (survey, MND, vaults, pavement restoration), updated as-built, Public Roadway Works Completion Certificate, and post-installation cable test results.
Yes. Hype Telecom operates underground infrastructure projects across different Brazilian markets, with the capacity to manage the regulatory process for each municipality — including city permits, traffic authorities, and utility companies — plus ART filings with the CREA of the corresponding state.
Through three mechanisms: (1) formal Technical Responsibility via ART with a licensed civil engineer; (2) prior interference survey using direct and indirect methods before any drilling begins; and (3) photographic and documentary records of every phase of the work, consolidated in the Data Book delivered to the client at project close.
