Hawaii BEAD: Connect Kākou and the $118M Savings Story

When NTIA approved Hawaii's Final Proposal on November 18, 2025, the state had committed approximately $30.7 million of its $149.5 million allocation to reach 7,033 eligible locations — saving $118.8 million through competitive market outcomes. The University of Hawaiʻi Broadband Office (UHBO) administers Hawaii's BEAD program under the Connect Kākou brand, and the award structure reflects the geographic and technological reality of serving a state built on isolated island archipelago with highly variable terrain and population density.

Hawaiian Telcom holds the fiber subgrant covering 5,748 locations (81.7% of the BEAD-eligible total) with a four-year performance period. As the incumbent local exchange carrier in Hawaii, Hawaiian Telcom's fiber deployment extends its existing FTTH network into gaps in its current service footprint — primarily in communities on Oahu, Maui, and Hawaii Island where the existing infrastructure is copper or coaxial but FTTH is not yet deployed. Amazon Leo holds the remaining 1,285 locations (18.3%) under a ten-year performance period using LEO satellite technology, covering the most remote and geographically isolated communities where the cost of terrestrial fiber construction is not recoverable under any grant structure. This includes portions of Molokai, Lanai, and remote rural areas of the Big Island where Hawaiian Telcom's existing network reach is limited by the terrain and population density required to justify aerial or underground construction. For any provider operating in Hawaii's BEAD program, OSP engineering begins with an honest assessment of what the subsurface and terrain will actually allow.

HECO and KIUC Pole Infrastructure: Two Different Attachment Processes

Hawaii's aerial pole infrastructure is owned primarily by two electric utilities operating under very different regulatory structures. Hawaiian Electric (HECO) serves Oahu, Maui, and Hawaii Island — the three most populous islands — and its joint-use pole attachment process is governed by the Hawaiʻi Public Utilities Commission (PUC), which oversees both electric and telecommunications utilities in the state. HECO's pole attachment process follows PUC tariff requirements and established joint-use rules, making it the more structured of the two major pole owners in terms of documented timelines and application requirements.

Kauai Island Utility Cooperative (KIUC) serves Kauai and is structured as an electric cooperative rather than an investor-owned utility. KIUC's pole attachment process runs through KIUC directly, without PUC oversight of the same kind that applies to HECO. Cooperative pole attachment terms in Hawaii, as in most states, are negotiated outside the FCC's formal pole attachment rate and access framework — which means timeline, cost, and access terms depend on the negotiation and the cooperative's existing joint-use agreement structure. Hawaiian Telcom, as the incumbent LEC, also owns telecommunications poles throughout the state and has its own make-ready processes for third-party attachments.

Our pole loading analysis for Hawaiian pole attachment applications evaluates the existing distribution loading on HECO or KIUC poles against NESC structural standards and the proposed fiber attachment parameters, accounting for Hawaii's specific wind loading zone requirements. Hawaii's coastal exposure means that poles in exposed locations carry higher design wind loads than equivalent mainland locations, and pole loading calculations must reflect the appropriate wind speed and ice (typically not a factor in Hawaii's tropical climate, but wind pressure governs) design criteria from the applicable NESC edition. In higher-elevation areas of Maui and the Big Island — particularly routes crossing saddle roads or summit approaches — wind loading design criteria increase substantially and can drive make-ready costs well above the coastal-zone baseline.

Volcanic Basalt Rock, Lava Tube Voids, and Subsurface Engineering

Every Hawaiian island sits on volcanic basalt, and the hardness of that basalt directly determines what underground fiber construction costs. Basalt compressive strength typically ranges from 150 to 300 megapascals — significantly harder than the limestone karst that creates drilling challenges in Arkansas or Iowa, and far harder than the sandy coastal plain soils common in the southeastern United States. Directional boring through fresh basalt requires tungsten carbide or polycrystalline diamond compact (PDC) drill bits, slower penetration rates, and substantially higher equipment wear rates compared to conventional boring through sedimentary soil formations.

On Hawaii Island specifically, the interaction between pahoehoe and aa lava flow types creates heterogeneous subsurface conditions that make pre-bore investigation essential. A directional bore path that begins in dense, competent basalt may transition within a few hundred feet into fractured lava rubble or unconsolidated cinder material from a later eruption event — and the bore equipment response to these transitions requires real-time adjustment. Lava tube systems present a distinct hazard: these hollow underground conduits form when the outer surface of a lava flow cools and solidifies while molten rock drains from the interior. A lava tube that intersects a bore path can cause the bore to break into an open void, resulting in drilling fluid loss, bore path deviation, and potential loss of the drill string. Known lava tube locations on the Big Island are documented but not comprehensively mapped, and bore paths should be evaluated against available lava tube surveys before committing to underground construction in affected areas. The steep topographic gradient from coastal elevations to summit slopes — Mauna Kea reaches 13,796 feet above sea level — means that cable routes must often traverse very short horizontal distances with significant elevation change, creating strain, temperature differential, and fiber management design considerations that don't arise on flat terrain.

Our field survey teams document subsurface conditions at each proposed bore location in Hawaii, including soil profile transitions, rock outcrop proximity, and any available geotechnical data for the specific route segment. This investigation step prevents the cost overruns that occur when underground construction bids are built on assumptions about soil conditions that the basalt geology doesn't support.

DLNR Conservation District and Cultural Review Permitting

Hawaii's DLNR administers the Conservation District, which covers significant land area on every island — including the upland forest reserves, watershed areas, and conservation zones that fiber routes commonly need to cross to reach communities above the coastal plain. Any construction in a DLNR Conservation District requires either a Conservation District Use Application (CDUA) or Conservation District Use Permit (CDUP) depending on the applicable land use subzone. This is a substantive review process with public notice requirements and agency response timelines that can extend to six months or more for projects in sensitive subzones such as Resource or Protective designations.

The State Historic Preservation Division (SHPD) reviews projects that may affect historic properties or archaeological resources under Section 106 of the National Historic Preservation Act. Hawaii has exceptional density of Native Hawaiian archaeological sites, traditional cultural properties, and historic districts that trigger SHPD consultation requirements. The Office of Hawaiian Affairs (OHA) is a required consultation party for projects affecting native Hawaiian cultural practices, traditional gathering areas, and historic sites — a consultation requirement that has substantive implications for route selection in communities on Molokai, the northern Kohala Coast of Hawaii Island, and portions of Maui's Hana Highway corridor. Routes designed to avoid DLNR Conservation District triggers may be longer and more expensive than straight-line paths, but the permit processing time saved by routing around Conservation District land frequently more than compensates for the added construction cost.

The as-built documentation packages for Hawaii BEAD projects must reflect permit conditions precisely — DLNR Conservation District permits typically include construction method requirements, seasonal work restrictions to protect watershed resources, and specific revegetation or site restoration obligations. As-built records that don't capture compliance with permit conditions create closeout risk and potential enforcement exposure for subgrantees.

Inter-Island Connectivity and Submarine Cable Engineering

Hawaii's geographic reality — isolated islands separated by deep ocean channels — means that inter-island connectivity is not an OSP engineering problem. It is a submarine cable engineering problem, and the two domains require substantially different expertise, equipment, and contracting structures. The Jones Act (Merchant Marine Act of 1920) requires that goods transported between U.S. domestic ports be carried on U.S.-flagged, U.S.-built, and U.S.-crew vessels. For submarine cable installation between Hawaiian islands, this requirement applies to the cable lay vessel and associated support fleet, limiting the competitive bidding pool to U.S.-flagged cable ships and materially increasing project cost compared to the global cable-lay market.

Inter-island fiber segments involve marine route survey, seabed geotechnical assessment, cable burial specification for the nearshore transition zone (where wave action and anchor drag are primary damage mechanisms), landing station engineering at each island terminus, and long-term operations and maintenance planning for an asset that cannot be accessed for repair without mobilizing a marine vessel. The terrestrial OSP portion on each island — the last-mile FTTH design that connects communities to the landing station or inland distribution point — is Draftech's primary scope, but the network architecture decisions that determine where the terrestrial network begins and ends must account for the location and capacity of landing stations and the inter-island cable system's topology. Draftech coordinates with submarine cable specialists on Hawaii inter-island projects to ensure that the terrestrial OSP design is integrated with the marine segment from the start, rather than discovering interface conflicts during construction.

Hawaiʻi PUC, IUC Regulation, and BEAD Compliance

The Hawaiʻi Public Utilities Commission (PUC) has unusually broad jurisdiction compared to most state utility commissions: it regulates both electric utilities (HECO, KIUC by certain matters) and telecommunications providers operating in Hawaii. This dual jurisdiction means that OSP engineers navigating pole attachment disputes, easement condemnation proceedings, or rate negotiations in Hawaii may find the PUC involved in proceedings that would, in most states, be handled by separate electric and telecom regulatory bodies. The PUC's telecom jurisdiction is relevant for Hawaiian Telcom's regulated operations and for any access disputes that a BEAD subgrantee might need to escalate above the utility's attachment operations team.

UHBO's BEAD subgrant agreements under Connect Kākou incorporate the standard NTIA BEAD compliance requirements — network performance standards, open access obligations during the performance period, and documentation requirements for construction completion. For Hawaiian Telcom's four-year performance period, the documentation requirement includes GPS-attributed facility records that the FCC broadband map reporting process requires, captured against the as-built network rather than the design drawings. For remote communities served under the Amazon Leo satellite allocation, the performance monitoring and compliance documentation structure is different from fiber — based on service activation records and speed test data rather than infrastructure location records. Draftech's as-built documentation workflow for Hawaiian Telcom BEAD projects captures facility location data in UHBO's required format, integrated with the NTIA broadband reporting structure from the start of construction rather than assembled after the fact at project closeout.
