Change In Estimate [Abstract]
Change In Estimates	NOTE 3: CHANGE IN ESTIMATES During the economic downturn we substantially reduced our workforce in the construction contract division keeping primarily key personnel on staff. In 2012, we significantly increased the number of construction contracts we were awarded, requiring a larger skilled workforce than we had in place. Finding the personnel with the needed skills proved challenging at best, requiring additional training of new personnel and, in some cases, contracting out work we had intended to perform in house in an attempt to meet construction deadlines. These factors continued to result in cost overruns and gross profit declines in our Ready Mixed Concrete Business during the second quarter ending June 30, 2013. The change in estimates in construction contracts resulted in a $0.7 million reduction in net income recognized during the second quarter of 2013.
