The order renovation work has to happen in, and why order beats speed

Richard Joseph Spinelli has watched renovations of prewar Bronx units go well and badly, and the difference is almost never the quality of the trades. It is the order. The sequence below is not a style of working. It is a dependency chain, and each stage exists because of what it would ruin if it came later.

First, find out what is actually there

Before anything is specified, open enough of the walls and ceilings to see the systems. In a building of this age the drawings, where they exist, describe an intention from a century ago rather than the current state.

This blocks everything. A specification written before anyone has looked behind the plaster is a guess, and every later stage inherits the guess.

Second, the things that are wet and the things that are live

Risers, supply, waste, and the electrical service. If any of these are being replaced or upgraded, they happen now, while the walls are open and before a single surface exists.

This blocks all finish work, permanently and expensively. A kitchen installed over a riser that needs replacing in four years is a kitchen that will be removed in four years. The decision is not whether to spend the money. It is whether to spend it now or spend it twice.

Third, the envelope

Roof, windows, anything that lets water in. Water is the only input that destroys work already completed, so it comes before completed work exists.

This blocks nothing directly and ruins everything indirectly. A perfect unit under a failing roof is a temporary condition.

Fourth, the layout decision

Where the walls go, and therefore how many bedrooms the unit holds.

This has to happen before finishes and after the systems are understood, because the systems constrain it. A bedroom cannot go where a riser has to run. This is the stage where the building’s real capacity is set, and it is set once for the next decade.

It is also the stage most vulnerable to a bad instinct. An open plan looks better on the walk through and sleeps fewer people. In a student building the awkward extra bedroom outperforms the handsome open room every year, without exception.

Fifth, the surfaces nobody thanks you for

Floors made level, plaster made flat, doors that shut, windows that operate.

This blocks the perception of everything after it. A well chosen kitchen in a room with a sloping floor and a door that sticks reads as cheap, and no amount of spending at the next stage recovers it. Students do not itemise this. They form an impression in the first minute and attribute it to something else.

Sixth, kitchens and bathrooms

The two rooms that get talked about, sixth in line.

They come last among the substantial items because they are the most vulnerable to everything upstream. A bathroom fitted before the waste stack is settled is a bathroom fitted twice.

Seventh, the standard, applied

The final pass is not a stage of construction. It is the check that the unit matches the written standard the company applies to every unit rather than matching whatever this particular set of trades happened to do.

This blocks the next five years of maintenance. Units built to a common standard can be maintained from a common stock of parts by people who already know what is behind the wall. Units built to whatever seemed sensible that month each require their own education.

What happens when the order is broken

Two failures, both common, both avoidable.

The first is finishing before investigating, which is the expensive one. Work gets done to a high standard on top of a problem that has not been found. The problem then surfaces, and the good work is demolished to reach it. This is how a renovation runs to twice its expected cost without anyone doing anything careless.

The second is running the schedule from the move in date backwards. August is fixed, and the temptation is to start from it and compress whatever stage is currently in the way. What actually compresses is investigation, because it is the only stage with no visible output. A unit delivered on time with an unexamined riser has not been delivered on time. It has been delivered on credit.

The rule underneath all of it

Every stage in this list can be done well and be worthless, if the stage before it was skipped. That is what a dependency chain means, and it is why Richard Joseph Spinelli treats the order of the work as a more important decision than the pace of it. A renovation that takes a month longer and is sequenced correctly will be a better building for twenty years. A renovation that hits the date by skipping the second stage will explain itself, eventually, in a February.
