Kiewit Luminarium

Omaha, NE
82,000 SQ FT
Luminarium
Mechanical Construction, Prefabrication

MMC Contractors performed the installation of all mechanical systems for the Kiewit Luminarium project — a STEM museum modeled after the Exploratorium that features two floors and a third for a mechanical room — including the plumbing, HVAC piping, and sheet metal.

Mechanical scope included chillers, cooling towers, two AHUs, and humidifiers to accommodate an art studio space. The AHUs were also selected at the height of the pandemic and our teams reconfigured them to allow for 100% outdoor air usage. Much of the piping and ductwork was exposed in this project, and our team utilized double-wall spiral piping to achieve a clean, industrial look.

The plumbing scope included a siphonic roof drain system and a suspended below-grade drainage system that utilized void forms to take into account the movement of the ground has close to the river near the site — the drainage piping is suspended from the poured floor.
