ALT-Facilities and Utilities Management

Public Works departments everywhere are experiencing alarming shortages of staff that threaten continuity of operations.

GHA is providing the experienced guidance and hands-on operational support needed to ensure delivery of essential services.

For some time now, Public Works has seen a decline in young people interested in pursuing careers within the industry. As a result, there have been fewer and fewer staff that develop into leadership roles. As time progresses, the staff who carry the crucial Public Works responsibilities reach retirement, leaving the agency and these services vulnerable.It is putting extra stress on villages, cities, townships, and counties.

GHA had a unique opportunity to develop solutions to the operations gaps when Mike Grinnell joined our team. Mike was previously a well-known and respected leader with Lake County Public Works, whose vast experience could fuel insights for GHA’s many projects involving public works coordination. This experience led to our ability to provide needed assistance with Water Operations for client agencies, as well as groundbreaking advances in manhole condition assessment technology.

This new collection of services was very well-received and further developed as we attracted other well-known leaders in the Public Works arena. GHA now provides a large range of key Operations services through the formation of our Facilities and Utilities Management Division.
