Peetz Wind Farm
CTL | Thompson provided services for 267 wind generator turbines, four electrical substations, and maintenance facilities in Northeast Colorado. Each turbine consisted of an approximately 260-foot tall tower with a 15-foot diameter base weighing approximately 25 tons.
A geotechnical investigation and construction materials testing services
Exploratory borings at each of the 267 tower locations, and additional borings at the substations and maintenance facility
Soil resistivity tests at 28 locations and seismic refraction studies at 80 locations
A geographical report with foundation recommendations for the wind turbine generators, electrical substations, and operation and maintenance building\
Construction observations and materials testing
An offsite office was set up with materials testing equipment, including a concrete compression machine, concrete cure tanks, and nuclear density gauges. Three technicians were provided on a full-time basis.
Providing a full-time staff of field technicians on-site was crucial to keeping the project on schedule and avoiding costly delays. The specific construction observations that our field representatives performed on the wind turbine projects included: excavation observations, compaction testing, reinforcing steel observations, concrete testing, aggregate testing, and concrete batch inspections.
