Tunnels are more confined so a string of lights down the length of the tunnel is enough to light their entire operation. We have a 96" tunnel being drilled for our outlet. A 500' x 500' x 35' tall concrete box is becoming a little more challenging. Generators outside the reservoir are expensive...
I have 250,000 sq ft of enclosed concrete reservoir that needs to be lighted for safety and completing punch list items. Does anyone know of temporary lighting options for very large areas?
Sorry for the typo. The allowable loss of height is 0.174 inches. The footprint of the reservoir is 259,750 square feet. The height at maximum capacity is 29 feet. So I guess you could say it is a shallow reservoir. With an allowable loss of 0.050% per 24 hours, the allowable head loss is...
We will be performing a leak test on a 55 million gallon concrete reservoir and are interested how others have measured the water loss. We are specified to follow ACI 350.1-01/350.1R-01 Tightness Testing of Environmental Structures with the HST-050 criteria. This criteria allows for a loss of...
