Why we only work where we work.

The geology textbook for our footprint is short. Along the Red River bottoms, we sit on Holocene alluvium — reddish silty clay and silt, soft when it's wet, stiff when it isn't, and saturated for most of the year. Step up onto the terraces and the section turns Pleistocene: tan and orange Prairie and High Terrace clays with basal gravels, the kind of stiff red clay that fooled half of north Louisiana into thinking subgrades take care of themselves. They don't. The reds shrink and swell with moisture, and basal gravel lenses show up where you didn't draw them on the cross-section.

Climb a little farther and you hit the Tertiary uplands. The Catahoula Formation — the late Oligocene unit named for Catahoula Parish itself — is the one out-of-state crews hear about and get nervous about. It's the gray-to-white sandstone, loose quartz sand, tuffaceous sandstone with volcanic ash, and brown sandy clay you'll cut into in northern Rapides and Grant. It's joined in the section by the Fleming members — Carnahan Bayou, Williamson Creek, Dough Hills — clay-and-siltstone units that share its bad habits when it rains.

“A Proctor curve is a starting point on this ground, not an answer. We don't compact a Catahoula clay the way you'd compact a manufactured fill out of east Texas. We test, we bleed it, we test again.”

What does that translate to on a job? Optimum moisture is a narrow window here, and the penalty for being two points wet is not a soft spot — it's a pumping subgrade that you can't proof-roll out of. We run a moisture-density check on every lift on production work, not just the ones the spec says to. We over-excavate where the section flips from terrace clay to alluvial silt, because the boundary doesn't respect the boring log. And we keep a stockpile of select material on every job that's bigger than the one the estimator drew, because we've never regretted having it and we have regretted not having it.

Alexandria averages just under sixty-one inches of rain a year. That's spread across all twelve months, which is the first thing visitors miss — we don't have a dry season, we have a less-wet season. Hurricane season opens June 1 and runs through November 30; the statistical peak is the second week of September. Our July and August are drier than our December and January. That fact owns more schedules than anything else on this page.

The way we read this table: mass earthwork sequences into the back half of summer. Concrete and structural work straddles the shoulder months. Land clearing slots into the fall when the burn windows are most reliable and the Catahoula uplands are at their friendliest moisture. Winter is for haul roads, drainage, and the work that doesn't care whether the subgrade is six points wet of optimum.

If a schedule was built three states away and asks us to turn dirt in February or run mass excavation in April, we say so at the bid table. We'd rather lose a week up front than lose two weeks on a re-pull.

Alexandria sits on the Union Pacific Alexandria Subdivision and on the former Kansas City Southern line that became CPKC after the Canadian Pacific–KCS merger closed on April 14, 2023. UP runs a yard in town and serves the Central Louisiana Regional Port. CPKC runs north-south through Rapides toward Shreveport and the Gulf. Two Class-1 connections is not the standard hand for a market this size, and on the right job it's the difference between a staging plan that works and one that lives on trucks.

Then the river. The J. Bennett Johnston Waterway — the Red River Waterway, in the way it actually gets called — is a commercially navigable channel from the Mississippi to Shreveport, 9 feet of depth and 200 feet of width minimum, with five Corps locks. The Central Louisiana Regional Port at mile 90, four miles northwest of downtown Alexandria, runs barge, dock, rail, and warehousing on roughly 200 acres. For an industrial pad of any meaningful size, staging select material by barge into the port and railing or hauling to the work is a sequencing option a Houston outfit doesn't typically have on the table.

“Knowing what arrives by barge versus what arrives by truck changes the bid — not by a percent, by a meaningful fraction of a percent on a job big enough to matter.”

The labor pool here is small and old. Most of our senior operators have fifteen to twenty-five years on this dirt, and a handful have spent every single one of those years inside our service radius. That isn't an HR talking point; it's the reason a foreman can call out a clay-to-sand transition through the cab glass before the survey rod catches up. It's why a dozer hand can tell you a section is going to pump before the moisture reading does.

Out-of-state crews ship in with that knowledge at zero, and they buy it back the hard way over the first month on the ground. Our crews bring it on day one. We pay for that; you do too. It is the single best line on the schedule.
