Concrete was provided by Irving Materials, Inc. (IMI), Greenfield, Ind., which had a primary plant and two portables set up on the jobsite. Concrete was delivered by 14 dedicated trucks on the job. The slab mix design was a 4,000-psi non-air mix with blended limestone and a mid-range water reducer, resulting in a 5-in. slump.

Concrete was discharged from trucks and placed by a 12-man crew equipped with a Somero S-240 laser screed for slabs on-grade and an Allen Engineering Magic Screed for tilt-up panels and decks. A variety of floor flatness hand tools was used immediately after the screeding process. Confilm by Degussa Admixtures was applied after the bump cutting to keep the top of the slabs from drying too quickly.

Concrete finishing was accomplished by a six-man crew using two Allen Razorback HD 550 riding trowels with Compodisks to break open the floor approximately three hours after initial strike-off. The panning operation was followed by an HD 550 Rider with combo blades. One hour after the combo blade pass, two HD 530A rider trowels were used for the final floor finish.

The concrete floors were specified at FF50 for flatness and FL35 for levelness with Local Minimums of FF35 / FL25. Ahal was pleased to achieve slabs in the high FF60s to the low FF70s, which greatly exceeded the specifications.

Once the floors were done, the tilt-up walls were set using a 240-ton crane. Ahal poured 36 wall panels per week and set the panels three days after they were poured.
