Open-cut, HDD, or microtrench? What controls the choice on a hyperscale fiber install.
Published 2026-05-10 · Backwell · Constantia, NY
Data centers are connectivity businesses first and computing businesses second. Every hyperscale build needs redundant fiber paths to diverse points of presence, plus inside-the-fence routing between buildings, between halls, and to the substation and security infrastructure. Backwell installs fiber routes for carrier laterals, dark-fiber backbones, and inside-the-fence runs across Central NY.
Open-cut trenching is the cheapest and fastest method for long fiber runs across open ground, and it is still the default on greenfield data center sites. Trench to 36 to 48 inches, place bedding sand, lay conduit on pull spacers, set warning tape, and backfill. Unit rates for open-cut conduit installation in CNY run roughly $14 to $30 per linear foot for a 2-inch conduit in normal soil, including bedding and warning tape but excluding the conduit material itself.
Horizontal directional drilling is the answer for crossings: roads, existing utilities, wetlands, paved parking lots, and any other place where open-cut would be too disruptive or too expensive to restore. HDD shots in CNY run roughly $35 to $90 per linear foot for a 4-inch HDPE pull, depending on geology, shot length, and conduit count. Glacial till and outwash soils drill well. Shale rock drills slower and the unit rates jump. Wet clay can heave the surface during the pullback and has to be planned around.
Microtrenching is a relatively new technique: a saw cut about 1 to 2 inches wide and 12 to 16 inches deep, fiber duct dropped in, and the slot grouted closed. It is fast and minimally disruptive on paved corridors and has become standard for last-mile telecom in cities. On a data center site, it is useful for short runs across paved access roads or parking areas where neither open-cut nor HDD make sense. Unit rates run $8 to $18 per linear foot.
Whatever method you use, the conduit specification matters as much as the installation. Schedule 40 PVC for most data center applications, sometimes HDPE for HDD pulls. Every conduit gets pull tape, locator wire, and warning tape at the engineered depth. We mandrel-test every duct after backfill to prove clearance, and we document the route on as-builts so the carrier or owner can pull fiber without surprises.
