There was nowhere to stage material at 111 West 57th Street, so the building went in through one opening

When a site has no yard the hoist writes the schedule rather than the trades, and the order of the whole build bends to what can pass through one opening on a given day.
The first question a superintendent asks on a site walk is where the material goes. Not the material that arrives in a year, the material that arrives on Tuesday, and on the courtyard site of 111 West 57th Street the honest answer was nowhere. This piece is for construction managers and superintendents on tight urban builds, and for developers who have never had to think about a yard because they have always had one.
The ordinary answer to a tight site is a laydown area somewhere near the work: a lot across the street, a closed lane, a corner of the site itself that gets built last. Deliveries come in, sit for a day or a week, and go up when the crane and the trade are ready for them. The yard is a buffer, and a buffer is what lets a schedule absorb a late truck or an early one without the whole sequence moving.
That answer did not apply here. The site was the courtyard behind a landmarked hall, hemmed in on every other side, with a single opening to the street. The street itself was 57th Street, and 57th Street cannot be used as a yard, on any day, for any reason a contractor would find persuasive. So the buffer did not exist, and a build without a buffer is a different kind of build.
What took its place was sequence. Every delivery had to be timed to arrive when the hoist was free and the trade was ready, because there was nowhere for it to wait. That sounds like a scheduling refinement. It is a change in who writes the schedule. On a site with a yard the trades set the pace and the logistics follow. Here the hoist set the pace, and the trades were fitted to what could pass through the one opening in the hours the site was allowed to use it.
In practice that meant the schedule was built backwards from the hoist. The team worked out how many picks the day could hold, what each pick could weigh and what it could measure, and then asked which trades could be fed by that many picks in that order. Some sequences that would be ordinary elsewhere were simply unavailable. Two trades that would normally overlap on a floor could not, because their material could not both come through the opening in the same window. So they ran in series, and the floor took longer.
Deliveries were booked to a window, and a truck that missed its window did not wait around the corner. It went away and came back, because there was no corner. The trades learned that a late truck cost them their slot rather than a few minutes, and the trades that did best on this building were the ones that treated the delivery window as an appointment with the hoist rather than a suggestion.
The material itself was designed around the opening. Where a panel or an assembly could be made in a size that passed through and lifted cleanly, it was. Where it could not, it was made in pieces and joined in the building, which is more work in the air and less work on the ground, and on this site the ground was the thing in short supply. A facade unit, a section of curtain wall, a mechanical skid, all of them were looked at first as objects that had to get through a gap, and only afterwards as objects that had to perform. The fabricators were told the dimensions of the opening before they were told anything else about the building, and more than one of them redrew a standard unit to suit it.
A construction manager reading this could say that this is how every dense urban site is run now, and that the courtyard only made explicit what a Manhattan build already knows. That is partly true and I would not argue against the general point. The difference is one of degree, and past a certain degree the difference becomes one of kind. A site with a small yard still has a yard. A site with none has to plan for the day the hoist is down, and a site like this has days when the hoist is down and nothing comes in, and the whole building waits. That is the reading a competent superintendent would push back on hardest: that the risk of a single point of entry was accepted rather than engineered around. I think it was accepted, because there was no engineering around it. There was one opening.
What it cost was time and a kind of patience the trades are not used to being asked for. The building went up in the order the opening allowed, and that order was slower than the order the trades would have chosen. Hoisting was sequenced, deliveries were sequenced, and the sequencing was the job. The people who carried it were the construction manager's logistics lead and a hoist contractor who understood that on this site the hoist was the critical path rather than a piece of equipment on it. Anyone planning a build on a site with no laydown should retain a logistics consultant before the schedule is drawn, and should let that person, rather than the trades, set the order.
At the end of it the street was still 57th Street, still not a yard, still carrying its traffic past a building that had been fed through a single door in its side.
