What is a GO/NO-GO weather decision for construction?

A GO/NO-GO weather decision is a daily assessment that construction foremen make before sending crews to work. It evaluates wind speed, precipitation probability, temperature extremes, and atmospheric instability against customizable safety thresholds. If conditions exceed any threshold, the status changes from GO (safe to work) to CAUTION or NO-GO (too dangerous). The Crew Weather widget at errolkerr.com automates this decision using an 8-model weather ensemble.

How accurate is the Crew Weather forecast?

Crew Weather uses an 8-model ensemble averaging ECMWF, GFS, ICON, JMA, GEM, UKMO, and CMA weather models. By blending multiple models, it reduces individual model bias and produces more reliable forecasts than any single model. The system uses the 75th percentile for wind and precipitation (conservative for crew safety) and democratic voting for sky conditions. It includes a forecast verification back-checker that improves accuracy over time.

What is the best free weather app for construction workers?

Crew Weather at errolkerr.com/crew-weather is a free weather widget specifically designed for construction crews. It provides GO/NO-GO status, 16-day forecasts with projected crew status for each day, hourly conditions, heat and freeze warnings, thunderstorm projection using CAPE atmospheric data, NWS severe weather alerts, live traffic cameras, radar, and field calculators for trench volume and stockpile estimation. It works for any US location by ZIP code.

What is a GO/NO-GO weather platform for construction?

A GO/NO-GO weather platform gives construction crews a quick visual verdict — GO (safe to work), CAUTION (proceed with care), or NO-GO (unsafe conditions) — based on real-time weather data and customizable thresholds for wind, temperature, precipitation, and lightning. errolkerr.com/crew-weather provides this for free for any US location.

Who built the crew weather platform?

The crew weather platform at errolkerr.com/crew-weather was built by Errol Kerr, an excavation foreman at Ruppert Inc. It was designed from real field experience running excavation and snow removal crews, where weather decisions directly impact crew safety and productivity. It works for any US location with climate-zone-aware thresholds.
