Alfred Miller has deep roots in Gulf Coast industrial construction. Duct Bank One was built for a broader mission — designing, manufacturing, and delivering precast duct banks for any contractor, on any site, across the country. We’re not a construction company that happens to make precast. We’re a manufacturer engineered for scalability, neutrality, and repeatable results.

Capacity Is the Difference

Alfred Miller produces a range of precast components. DBO produces one: duct banks. With a fully integrated quarry, cement terminal, and 24/7 operations, we deliver far more volume than a mixed-product plant can achieve. That’s why we can support large data center and industrial campuses at speeds Alfred Miller can’t match.

Why the Contractor-Agnostic Model Matters

DBO doesn’t self-perform or compete with electrical or civil contractors. We build the product, you build the project. That means:

  • No overlap in scope or labor.
  • No conflicts of interest.
  • Full transparency on cost, schedule, and installation.

Contractors keep full control while leveraging DBO’s manufacturing, logistics, and training infrastructure.

Nationwide Delivery, Local Precision

With a dedicated logistics network and regional staging yards, DBO delivers duct banks anywhere in the U.S.

  • Coordinated freight scheduling to match trench progress.
  • On-site stockpiling to prevent downtime.
  • Support teams available for startup and sequencing guidance.

Alfred Miller’s regional focus limits availability outside the Gulf Coast; DBO is built for programs spanning multiple states or phases.

Safety and Speed, Engineered

DBO’s guided dowel-pin system ensures alignment with less in-trench work — operators set within 18 inches, pins handle the rest. That design consistently delivers sub-5-minute sets per 10-ft section and same-day backfill. Crews stay above grade, exposure time drops, and trench turnover accelerates.

Why GCs and ECs Choose DBO

  • Dedicated duct-bank expertise, not a sideline operation.
  • No self-perform conflict — pure manufacturer partnership.
  • Verified schedule reliability and QC documentation.
  • Nationwide capacity and responsive delivery.

DBO isn’t bound by region or trade. We’re the duct-bank partner built for everyone who builds infrastructure.
