Building through a Texas summer: heat, crews and the schedule

By two in the afternoon in late July the slab on a Houston job site reads well over a hundred degrees, and a framing crew that put up a wall an hour in the morning is putting up half a wall an hour now. Nobody is slacking. Bodies slow down in that heat, and any schedule that ignores it is a schedule that will be wrong by August.

Plan the summer months at a different pace

We do not schedule a July at the same production rate as a March. The look-ahead for exterior trades in summer assumes shorter productive days and more of them. That means framing, roofing, concrete and site work either get more calendar days or more people, and we decide which at the planning stage, not in the second week of a heat wave. A schedule that promises a November opening should show the summer slowdown in it already. If it does not, the date is fiction.

Dawn starts and afternoon trades

Exterior crews start at first light through the hot months, sometimes earlier when the city's noise ordinance allows it. That shifts everything around them: concrete trucks ordered for six in the morning, deliveries before eight, inspections requested for the morning window. The afternoon goes to interior work in whatever part of the building is enclosed, or to layout, material staging and cleanup that do not need a crew on a roof at three o'clock.

Once a building is dried in, the whole schedule tilts indoors. We sequence summer projects to get the roof on and the glazing set before the worst weeks, then move drywall, millwork, tile, paint and FF&E into the conditioned or at least shaded interior. Temporary cooling in a closed building is not a luxury on a hospitality or clinic build-out with a fall opening. It is what keeps the finish trades at full speed.

Concrete does not wait for the crew

Hot weather concrete is its own discipline. High temperatures pull water out of the mix before the finishers can work it, which means a slab that flashes, cracks or cures unevenly. Our concrete crew pours large slabs at dawn, keeps the trucks moving so the mix arrives fresh, uses retarding admixtures when the mix design calls for them, and wets the subgrade before the pour so it does not drink the slab. A pour that goes wrong in July is a demolition and repour in August, and that is a month a schedule does not have.

Materials have temperature limits

Roofing membranes, sealants, adhesives and some paints carry manufacturer temperature ranges for application. Push past them and the product fails early, sometimes within the warranty period and sometimes just after it. Our roofing and paint crews work to those ranges, which usually means mornings, and the schedule reflects it. Equipment feels the heat too. A lift or a compressor that overheats at noon is idle until it cools, so we rotate machines and keep spares on the bigger jobs.

Heat safety is a schedule tool

Water, shade, rest breaks every hour in the hottest stretch, and a superintendent watching for the early signs of heat illness. That is required and it is also practical. A crew that is managed through the heat comes back tomorrow. A crew that is pushed through it loses people to sick days and turnover, and a job that is short two framers in August is a job that is late in October.

A principal of our company is on the site every day, including the hot ones, which is how we know when the afternoon has to be called early and when a crew can push. Send over the drawings and the opening date you need, and we will build a schedule that already knows what July does to a job.
