Fort Collins Loading Dock Concrete

A dock estimate comes back with four line items and the capital request covers about half. That's the conversation we have most often on the industrial and flex property along the south and east sides of this city, out around The Landing and off Harmony. Nobody's arguing about whether the concrete is bad. They're arguing about which bad concrete gets fixed this year.

Fair argument, and it has a right answer, but only once you see that a dock isn't one structure. It's four things sharing an address. They fail on separate timelines, and deferring one costs almost nothing while deferring another quietly damages everything around it. Here's how we rank them when the money is finite.

Four structures, one name on the work order

The approach slab is the concrete a trailer backs across and parks on. Heaviest, most repetitive load on the property, and it sets the geometry everything else depends on.

The pit is the recessed box at the door: floor, walls, and the pour carrying the leveler and bumpers. Small, expensive per square foot, and the hardest piece to reach once anything gets rebuilt around it. The drive-in apron, where a property has one, takes lighter and slower loads but concentrates water on a grade. And the dolly pad, that small flat area where hand trucks and people come off the dock, is the least structural piece, the most likely to draw a complaint, and the cheapest thing here to correct.

Owners tend to fund whichever piece looks worst. It's rarely the piece doing the most damage.

Where a partial dock budget should go first

The one that never gets deferred

If the approach dropped, fix the approach. Everything at a dock is a height relationship: trailer bed, dock floor, and the leveler bridging between them. Levelers have a working range and it isn't generous. Let the approach settle a couple of inches and every trailer sits lower than the equipment expects, so the leveler runs at the bottom of its travel and the plate slams every time a truck pulls away.

From there it spreads. A tipped slab pushes against the pit wall instead of resting beside it. Bumpers stop landing where trailer frames hit them, so impact transfers into the wall and the door frame. Meanwhile the maintenance budget keeps buying leveler repairs on equipment working exactly as designed, over a surface that isn't.

Scheduling dock work in a northern city

Our season is shorter than the metro's and dock work is the least flexible thing on a commercial calendar, so the two collide constantly. Book early. A rebuild planned in January and placed in May goes smoothly; the same job decided in September becomes a fight with overnight lows and a cure clock nobody wants to shorten.

Winter is also when a bad dock does most of its damage. Snow comes off trailers and lands in the same spot, the pit collects meltwater with nowhere to go, and thaw and refreeze works on every crack in the approach. Add whatever the snow crew is spreading. A dock that's on the fence right now will not be on the fence after March.

We stage the work door by door: one position out at a time, a temporary route for hand trucks, and a schedule your receiving lead gets in advance.

What a dock scope from us actually includes

• Elevations shot across the approach, so settlement is a measurement, not an opinion
• Demo and haul-off of the old slab, including the steel that slows demo down
• Subgrade correction and free-draining base placed in compacted lifts
• Heavy reinforcement sized for repeated trailer and landing gear loads
• Doweled joints where the new slab meets the pit and existing pavement
• Pit drain checked, cleared, or replaced while the area is open
• Slope set to move water away from the wall to an actual outlet
