Segment Reporting [Abstract]

SEGMENT REPORTING

NOTE 14 - SEGMENT REPORTING

The Company's reportable segments are determined and reviewed by management based upon the nature of the services, the external customers and customer industries and the sales and distribution methods used to market the products.  The Company organizes its reportable segments to correspond with its primary service lines: wireless communications, specialty construction and electrical power.  Management evaluates performance based upon income (loss) before income taxes. Corporate includes corporate salaries and external professional fees, such as accounting, legal and investor relations costs which are not allocated to the other segments.  Corporate assets primarily include cash and prepaid expenses.  Segment information presented below with regard to the operating results no longer includes amounts related to the St. Louis and Sarasota Operations, which were sold September 1, 2011, and subsequently reported as discontinued operations as more fully described in Note 13.  The St. Louis and Sarasota Operations were previously reported in the specialty construction and wireless communication segments, respectively. Segment results for the years ended April 30, 2012 and 2011 are as follows:
