How do you know your $70 million dollar concrete pour is the correct temperature in 0 degree weather?
MKK is an engineering and construction company formed by a joint venture between Washington Group International (formerly Morrison Knudsen Corporation), and Kiewit Western Company. Construction of the I-25 interchange is a combined project with the Northwest Parkway Authority of Colorado. When completed, the $1.3 billion E-470 toll road will run 47 miles along the eastern perimeter of the Denver area. During the winter of 2001, MKK began pouring the concrete for the I-25 interchange. MKK used multiple echo data loggers (-29C) with SP16 probes that were inserted within tubes in the concrete to monitor the temperature as it was poured. Quality was assured.
