Does a new slab need time to cure before racking goes in?

Yes, concrete needs adequate cure time before it can reliably take anchor loads. Installing too early risks anchors that don't hold properly, so this is worth confirming against the slab's actual pour date, not assumed.

What should be included in an installation handover?

At minimum, a load sign for each bay configuration and documentation of what was actually built. An as-built layout is worth asking for if anything changed from the original plan during installation.

How is aisle width decided during installation?

By the forklift or truck that will actually operate in that aisle, checked against its turning and lift requirements, not by a general assumption about what's typical.

Should a new installation be checked before it's loaded?

It's worth arranging for someone competent to look over a finished installation before it goes into regular use, especially on a first installation with no inspection history yet to compare against.

What a New Racking Installation Should Include

A racking installation is more than standing frames up and bolting them down. The floor has to be ready first, the layout has to be set out accurately, and the handover at the end should leave you with more than an empty warehouse full of steel.

The floor comes first

The concrete slab the racking bolts into needs to be cured, flat and rated for the point loads the anchors will apply. Installing into a slab that isn't ready, whether it's too new, cracked, or simply not rated for the loads involved, is a problem that shows up later as anchors that don't hold or a floor that fails around them, not at the time of drilling.

This is often the step that gets compressed under time pressure, because the racking itself is the visible part of the job and the floor is easy to assume is fine. It's worth confirming rather than assuming, particularly on an older slab or one that hasn't carried point loads like this before.

Setting out the layout

Before anything gets bolted down, the layout gets marked out: row positions, the aisle widths matched to the forklift that will actually be using them, and clear height confirmed against the building. Getting the aisle width wrong by even a small margin can mean a forklift that doesn't turn cleanly into every bay, which is expensive to fix after the fact and cheap to check before.

Line marking usually follows the same setting-out data, so getting it right once at this stage saves redoing both the racking layout and the floor marking later.

Bolt-down and checking plumb

Anchors go into the positions marked during setting out, frames get checked for plumb before the beams go on, and beam connectors need to fully engage their locking pins, not just sit in place. None of this is glamorous, but it's the difference between an installation that's structurally sound and one that merely looks finished.

Row spacers and base plates get fixed as the frames go up, not left until the end, because a run that's out of alignment early stays out of alignment once every bay is bolted down. Any protective accessories the layout calls for, guarding at the end of an aisle or around a column near forklift traffic, are usually easier to fit at this stage than retrofitted once the racking is loaded and in daily use.

What a proper handover includes

A finished installation should come with a load sign for every bay configuration, documentation of what was actually installed rather than just what was quoted, and ideally an as-built layout rather than the original plan if anything changed on site. Arranging for someone competent to check the finished job before it goes into service is worth doing regardless of who installed it, particularly on a first installation where there's no prior inspection history to fall back on.

A new installation is also the natural moment to think ahead: whether expanding it later is likely, and whether the brand chosen now makes that straightforward or difficult in a few years. If the installation is actually part of a full site relocation rather than a first fit-out, the same setting-out and handover standards apply, even though the components themselves are secondhand.
