Stater Bros. Markets

San Bernardino, CA

Clarion Construction is proud to have worked as a subcontractor to Oltmans Construction Company, the general contractor on this prestigious project.


The entire building features a Fricks specialty floor. Here the west dock offers an abundance of work area.


The south portion of the west dock has a catwalk to keep pedestrians away from the forklift traffic. This area also features “Knock Out” doors at each of the loading positions. Another nice feature is the pallet storage directly under the catwalk at each loading position.


Frazier racks are standard throughout the over 700,000 sq. ft. of cold areas.


HCR double and triple air doors are fitted to the various freezer rooms.


All high traffic areas have 4 foot or 6 foot reinforced concrete curbs. The facility has sanitary finishes throughout.


A state of the art ammonia refrigeration system provides the cold for all of the freezers, coolers and dock areas.


Cleanly situated and insulated vessels store the ammonia for the refrigeration compressors.


24 penthouses enclose the multitude of coils required for the refrigeration system. TPO roofing over Dow insulation covers the entire facility.
