Change in Accounting Estimate [Abstract]
Changes In Accounting Estimates	3. 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 resulted in cost overruns and gross profit declines in our Ready Mixed Concrete Business during the third quarter and the nine months ending September 30, 2012. As a result of the change in estimate in construction contracts, a loss of $2.7 million was recorded during the third quarter of 2012.
