R.J. Daum worked as the structural concrete subcontractor at East Valley High School No. 1A for Turner Construction. This project consisted of nine separate buildings (approx. 105,000 sq. ft. of slab on grade.), and cast-in-place stairs. R.J. Daum cast approximately 5800 cyds of structural concrete and 1,000 cyds of lightweight concrete on metal deck. One of the many challenges on this project pertained to the foundations. Not only were the foundations large, but it also required methane barrier installation over the footings to protect the concrete from contacting the soil. A mudslab was cast on top of the footings. This allowed various trades the ability to work on top of the mudslab without damaging the methane barrier. Even with the challenges posed on this project, R.J. Daum completed the critical path structural concrete work six weeks ahead of schedule.

R.J. Daum performed the structural concrete work on this project as a subcontractor to Turner Construction Company. The project was a Central Utilities Plant to support Miller Children’s Hospital. R.J. Daum’s work consisted of anew mat foundation over methane-gas membrane system, continuous footings, slab on grade, high-lift cast-in-place concrete walls, concrete on metal deck, and miscellaneous concrete pads. The project also included footings for site shotcrete walls and cast-in-place site stairs.

The Emergency Operations Center Project consisted of three separate projects, Dispatch Center, Parking Structure, and Fire Station No. 4, located on the same site. R.J. Daum served as the structural concrete contractor for S.J. Amoroso. R.J. Daum poured approximately 48,740 sq. ft. of Slab on Grade at the Dispatch Center, in addition to 141,069 sq. ft. of light weight concrete. A major feature of the Dispatch Center was its design. A moat retaining wall was built around the perimeter of the building. The building itself was built on top of spring-loaded concrete piers that allowed the building movement in the event of an earthquake.
