Women Business Owners Need Retirement Plans
If you’re a woman who owns a business, you’ve got plenty of company. In fact, women own more than 10 million U.S. companies, and women-owned businesses account for about 40% of all privately held firms in the U.S., according to the Center for Women’s Business Research. Clearly, the good news is that women like you are entering the small-business arena at a rapid pace. The not-so-good news is that you may be facing a retirement savings gap in comparison to male business owners.

Code Adoption: The Fiscal Impact Statement
Local jurisdiction code adoption varies from area to area and some have placed more stringent requirements around financial impact analysis for not only new building codes but for any new law or changes to existing laws. This is typically called a fiscal impact analysis or statement and through the code adoption process over the years we have experienced this analysis requirement in various states including Indiana, Ohio, Iowa and others.

Elevator Code, CE Code and the NBCC — consistency of requirements
Historically, this subject was always a source of confusion to the electrical designers, installers and regulators, as provisions of the Elevator Code have not always been accurately correlated with the National Building Code of Canada (NBCC) and with the Canadian Electrical Code. Fortunately, some provisions for the electrically connected equipment used in conjunction with elevators have been harmonized in the latest editions of the Elevator Code and the NBCC.
