Pioneer State Mutual Insurance Company is a Michigan-based insurance company that provides residential, automotive, and commercial insurance policies.Pioneer State Mutual is one of the oldest insurance companies in the United States – the company has been in business for over 116 years. Pioneer was originally founded in 1908 as a farmers insurance company.
The project included the removal and replacement of the exterior front entry to Pioneer State Mutual’s headquarters building.The steps and adjacent sidewalks included hydronic heating and were poured with integral concrete coloring.The exterior concrete was cured with water paper for seven days.
Because of the design of the cantilevered step face / reveal, every step had to be placed and finished before the next step could proceed. There was also no way of attachment in the forming process, and no anchors of any type could be put into the brick or previous step. Streeter’s crew had to pour concrete deadheads to brace the formwork, along with turnbuckles and long bracing from the bottom.
Further complications were created by the forming process. Since it involved so much bracing and deadhead concrete weights, the crew could not see the previous steps poured which had hand-tooled joints placed 4-foot on center that all had to be perfectly straight, top to bottom, once it was complete.
With a schedule that included one pour per week, the job took just over two months from start to finish, including the application of a color seal to get a uniform and consistent look across the entire steps and sidewalk
