Justin is in the building’s east wing at three in the afternoon and has been measuring the same return-air column for forty minutes, because the column’s specified diameter and its actual diameter are not the same diameter, and the architect on the project has gone home to Birmingham and will not be back until Thursday, and Justin has decided that he is not going to ship a system with a two-percent tolerance break in the service of an architect’s deadline. The column is sleeved with galvanized stock that is closer to twenty-eight gauge than the twenty-six the spec calls for. Justin writes this down. He writes down the manufacturer of the stock. He writes down the inspector’s stamp. He drives back to his shop in Arley.
The shop is fifty-three minutes from the building. The drive home from the shop is another nineteen minutes. Justin makes both drives in the same car, which he has owned for twenty-one years, with the same radio on the same Cleveland-Tennessee gospel station, which he has listened to since the boys were small. The boys are at the house when he gets back. The older one is reading at the kitchen table. The younger one is fourteen and is in the garage, working on a piece of code that does something to a directory of wedding photos for a shop in Pelham that is paying him eighty dollars to make the dropdowns work. Justin does not understand exactly what his son is doing. He also does not need to. The boy will come in for dinner.
He sits down at the workbench in the back of the garage. He opens the spec binder. He goes to the page where the cooling envelope is laid out. He adds, in pencil, a tertiary chiller and a separate water loop. The architect did not ask for one. The contracting firm did not ask for one. The state energy code does not require one. Justin includes one anyway, because the rule his own father had written down in the margin of a 1962 spec book was that systems with two failure modes will eventually find both at the same time, and Tuesdays are when that happens. Justin’s father had died in 1981. The spec book was on a shelf above his head as he wrote.
He closes the binder. He goes inside. His wife has set the table. The older boy has put the silverware out. The younger boy has come in from the garage with grease on his thumb and is washing it off with a yellow bar of soap from the kitchen sink that his mother has been buying from the same Arley feed store since he was seven.
They sit. Justin reads from the eighty-fifth Psalm in the King James because the King James is what his father had read to him at this table in this house in this kitchen, and he is not going to read anything else now. He says grace. They eat.
Twenty-four years later — the same kitchen, the same chairs, his younger son fourth in line at this table who-will-by-then-be-a-man and have a son of his own — that tertiary chiller will be the only reason a Cogent-leased cage in the same building’s east wing stays inside its thermal envelope through the August heat wave of 2021, which will be the only reason the social network which goes live two months later goes live two months later, which will be the only reason the man Justin’s son becomes will have made the decision he makes, the way he makes it, on the morning he makes it.
Justin will not know any of this.
He goes to bed at nine-forty-five.
He gets up at five-thirty.
He goes back to the building on Wednesday.
