A much-needed Gerdin Business Building expansion is under way. Work on the $28 million, three-story, 45,000 square foot addition started in February. The expansion is expected to be complete in the fall 2020, with classes being held in the new space beginning January 2021. The need for the addition is evident. Over the past six years, enrollment in the college has increased by 40 percent. BNIM of Des Moines and Story Construction of Ames are the design-build team for the addition, which is being constructed on the east side of the Gerdin Business Building, facing Wallace Road.

Week of July 29

Here is a brief update on the progress of the addition to the Gerdin Business Building.

  • The concrete ceiling for the mechanical room has been poured. This will also become part of the floor of one of the ground floor classrooms.
  • The construction crews are currently backfilling and compacting the soil that was excavated on the inside of the foundation for the rest of the addition. Once backfilling and compacting has been completed, the concrete for the remainder of ground floor will be poured.
  • Demolition of the limestone and the brick on the outside of our current Gerdin Business Building that must be removed to accommodate the addition has been started. This work will continue for the next couple of weeks.
  • The erection of the structural steel for the addition is scheduled to start the week of August 12.

Week of July 8

The expansion to the Gerdin Business Building is proceeding well. Here is a brief update on the activities that have been completed.

  • The walls and floor of the basement mechanical room have been poured.
  • The construction crew is working on the rest of the concrete foundation and should finish pouring the remainder of the walls later this week or early next week.
  • The air handling unit for the new addition has been set into place in the mechanical room.
  • The size of the sanitary sewer outlet pipe has been increased to accommodate the bathrooms in the new addition.

Upcoming activities in the next two weeks include:

  • Backfilling the area around the foundation
  • Installation of the ground floor deck (floor).

Wallace Road closed May 13 directly south of the entrance to the top portion of the East Campus Parking Deck. The south entrance to Farmhouse Lane will be closed as well. That portion of Wallace Roadwill be closed for the remainder of the construction period for the new addition to the Gerdin Business Building. The sidewalk along that portion of Wallace Road will be closed as well.

To get to the Gerdin Business Building from the East Campus Parking Deck, you can walk out the north end of the parking deck, cross Wallace Road, and either go through Heady Hall or take the sidewalk between Heady Hall and the Food Sciences Building to get to Farmhouse Lane. You can then go south on Farmhouse Lane until you get to the handicapped entrance at the northeast corner of the Gerdin Business Building, which will remain open. Alternately, you can walk out the south end of the East Campus Parking Deck to Union Drive and take the sidewalk along Union Drive to the south entrance to the Gerdin Business Building.

Week of May 28:

Drywall workers cover the interior Gerdin Business Building windows that face the expansion construction site.

Although the rain that has occurred the last two weeks has slowed the construction on the Gerdin Business Building expansion project, good progress on the expansion continues to occur. The majority of on-site construction activity involves the pouring of the concrete perimeter walls for the basement mechanical room. While foundation work continues outside, mechanical and electrical contractors are working on new plumbing connections and disconnects inside the existing building. They have also been constructing temporary walls on the inside of the south and east facing corridors on ground, first, and second floors. These walls are necessary to seal off the interior of the building from exterior construction activities as windows are removed and other demolition and construction activities occur on the exterior face of the building.

Week of April 22:

·         As part of the Expansion project, Wallace Road will be closed for over 1 year beginning the week of May 13. To improve traffic at the intersection of Wallace and Beach, temporary traffic signal installation is underway.
