The van

Hard to find.

Not one notepad — the ugly kit the warehouse never stocks. Affiliates and plants sit on the right rail later.

Field

Waterproof field books

Rite in the Rain class. Concrete + rain + a cheap legal pad is how RFIs get lost.

Field

Cylinder molds + slump cone

ACI field kit. If the lab forgot the can, the pour waits.

Field

Concrete blankets

Cure in January. One cold night without them is a broken slab.

Field

Form oil / release

The 5-gallon nobody remembered. Bonds the form to the wall.

Field

Rebar caps

OSHA and flesh. Cheap. Always short.

Field

Expansion joint + backer rod

The linear foot that is never on the truck.

Field

Cure and seal

Broom finish that dusts off in a month if you skip this.

Field

Keel / lumber crayon / soapstone

Marking wet concrete and steel. Not a Sharpie.

Field

Finish kneeboards

Edgers, groovers, mag floats that don't live at the box store at 6 a.m.

Field

Snap ties / wedge bolts

Wall forms. Specialty, not big-box.

Field

Diamond blades (green concrete)

The blade that doesn't glaze. People search this angry.

Field

FR shirts / pants

Required on plants and some GCs. Hard size run.

Field

Gas monitor + calibration gas

Confined space. A reminder with a vendor slot.

Field

Pipe wrap / underground tape

The roll that is always the wrong width.

Field

Compact rotary laser

Layout when the surveyor already left.

Field

Pin flags / whiskers / hubs

Dirt work. Boxes of 100 that vanish.
