"Floorless" Haz-Mat Buildings

Behind overhead steel pipe supports is a beige painted Haz-Safe "Floorless" modular building. There are two modules bolted together sitting on user's 5' steel reinforced concrete curb, which is a containment sump. Inside the building are large oil tanks, lots of plumbing, pumps, ect. The sump is sized to catch a combination of the largest tank spillage and 30 minutes of fire suppression sprinkler discharge water. Below is a graphic simplification of how a Haz-Safe "floorless" building "bolts" together using patented hardware...

Haz-Safe Buildings by Design premanufactures all weather "Floorless" or "Drop Over" multi-purpose buildings with proper selection of exterior and interior material, finishes and hardware are virtually no maintenance, are not susceptible to decay or rust, and are fully equipped as described in this website as well as any other industrial component appropriately applied on or within the structure. "Floorless" Buildings can be either whole single unit(s) or multiple modules to be placed on either the curb of a concrete sump floor or on a flat foundation. They can be blast and fire rated or not with exterior finishes from natural looking cedar shake siding to aggregate stone and interiors from porcelain enamel steel to fiberglass reinforced board panels. Whatever it takes.

Typical Installation of Modular "Floorless" Inplant Building Show/Hide

Typical Outdoor "Floorless" Haz-Safe Building Show/Hide


The two modular units were shipped seperately, bolted together on the parking lot pavement, and then the whole building was lifted onto user's previously prepared concrete curb, which is part of a continuous concrete pour with a sump floor. There are three bolt-up tubes, which are an integral part of the supports for a grated elevated floor, that came with the building.	Back side of same building showing the bolt-up 1" dia. rods still need to be cut off and the roof cap needs to be installed. User wanted as little of the concrete curb to be seen and made sure the grassy ground had plenty of fall away from the building. The installation was in deep southern USA so ice and snow buildup wasn't a problem

Corner of interior floor area shows the concrete sump floor and walls or curb as well as the user's special use piping. Fiberglass floor grate is removed to show 4" x 4" tubular beams used to support the grating above the concrete sump. Adjustable shelving has rubber grommet over the edge of 1" containment lip.	Workers are standing on elevated fiberglass flooring at the modular split of the building. Again, it is easy to spot 4" x 4" tubular steel floor supports on two foot centers just under the grating. Shelving on right is suspended from the ceiling to make it easy to remove grating from under lowest shelf.


"Floorless" building arrives bolted together. Placed on parking lot pavement, disassembly begins by removing roof cap.	Interior shows porcelain enamel steel finished fire, blast and sound rated walls. Blue tape holds pre-cut joint wall trim bar yet to be installed.	Forklift positioning itself to help pull two modular halves apart. Fire, blast and sound rated door shipped separately.

Seperated half of building is being forklifted and shoved towards facility's enterance while other half waits.	First modular unit to enter a door that was too small for a single non-modular unit to enter.	Once inside, user's installation crew re-bolted building back together, then forklift pushed whole building on crawlers into facility corner.

Forklift going inside building to get a better grip in order to maneuver building into facility's corner walls.	Short building on left is a conventional block constructed engine test cell of which the Haz-Safe version out-preforms.	Doors are being hung. User will test auto engines and later ship "floorless" building to Brazilian engine company.
