The Delaware County’s new Sheriff’s Office and Correctional Facility is located in Manchester, Iowa. The new building consists of 27,315 square feet of sheriff offices, jail cells, and additional recreational space for Delaware County’s police department.
Precast concrete panels were chosen for this project to provide the skeletal framework of the building. The exterior panels were produced with a black mix design and finished with a mixture of sandblasting and acid washing techniques to create a contrast in both texture and color. The black mix design was used for the building’s exterior panels to provide a modern industrial look. Sandblasting and acid washing allowed for an even rock exposure across the totality of the building. The front office panels were designed with the lower fourth of the panel each having four rows of horizontal reveals. Each reveal was heavily sandblasted to create a lighter color and heavy contrast compared to the black design of the panel. The overall effect is an eye-pleasing architectural design.
213 insulated precast concrete wall panels were produced for the project. Panels ranged in size - reaching anywhere from 13 to 26 feet in height. The precast concrete exterior shell of the building was erected in only eight days.
Precast concrete was chosen for this project due to its many benefits of strength, durability, high thermal ratings, and product longevity.
