Every unit knows
where it goes.
Sequenced delivery, from the takeoff to the wall. We count the building one opening at a time, agree the order with your site, then make, ship and label the windows in that order, so the units the site needs next are the ones that arrive next.
It starts with a good count.
Every opening on the drawings is counted and given a number of its own, by building, by elevation and by floor. Two openings can take the identical window and still be two numbers, because they are two places on the building.
The takeoff sorts any of those ways. Ask for one floor, one elevation or one building and the list is already there. Everything after this depends on it.
Your site sets the order.
Before anything is made we ask the site which elevation or which floor it wants first, and when. The answer depends on how the hoist runs, where the scaffold comes down first and which floors will be closed in.
That conversation decides the order of manufacture and the order of loading. It is the site's sequence, not ours.
The right windows on site, when the site needs them.
A large building is not one delivery. It can be twenty containers, staggered over two months. Our job is to make sure that the windows and doors the site needs next are the ones on the next container, and not the ones for a floor that is a month away.
So the windows are made in the agreed sequence, and each container is filled with the floors and elevations that come next on the list. A container is unloaded to the ground within about two hours of arriving, and the site then moves the racks to their floors over the next day or two. Each container has its own packing list, and units are ticked off as they come off the truck, so a missing unit is found at the truck and not at the opening.
A sticker on every unit.
Every piece carries a sticker with its opening number, its floor and elevation, and its type. When an opening ships in more than one piece, each one says so: item 1 of 2, item 2 of 2. The number is the one on the shop drawings: the tag over that opening on the elevation and on the plan.
A unit goes to one opening. Nobody on the floor has to measure a window to work out where it belongs.
What the site needs ready.
An unloading window agreed ahead of time, a forklift or a hoist that can take the racks, and dry, flat storage on the floor the units are going to. We send the site readiness checklist before the container does.
Crews that use the Install app check each unit in against its opening, floor by floor, and sign off each opening when it is installed.
