Building Alaska S09E05 - Playing Catch Up

All three builds are running behind schedule and must rush to get ahead. John and Heather build a water catchment system but discover they aren't getting enough water pressure, Chris Maynard's windows are delivered by helicopter in a dilapidated crate that swings violently in the wind, and Josh comes dangerously close to tipping over his forklift and knocking over a gable wall.
