Laser Precision

Photograph by: Chris Fox

Date of Photograph: August 4, 2011

In this photo you see a surveyor using a laser transit to set a benchmark to ensure that if the crushed stone moves before the concrete pour, the crew will be aware by checking the benchmark. The hose you see is a sump pump that continually pumps water out of the crushed stone base to ensure no water will come in contact with the concrete as it is poured and cures.

Photograph 28 of 45 in the "Horseshoe Falls Gallery" gallery
