Rapid, problem-free erection of theprecast prestressed concrete components on this baking facilityreduced construction time by morethan 40 percent over the alternatebuilding systems which wereconsidered. According to thegeneral contractor, this buildingsystem allowed the owner to quicklybring on stream a new operationwith improved process flow andmore efficient production. Erectionof prestressed concrete componentstook just 18 days. As parts of thecompleted building, the componentshad to meet stringent sanitaryrequirements. The hard surfaces ofprestressed concrete are easy toclean and contain almost no areafor dirt and dust to collect.

Meeting the strict FDA requirementsfor sanitation was the primary concern for the designers of this foodprocessing facility. The smoothinterior walls and roof of a totallyprecast prestressed concretebuilding proved to be the idealsolution. “The hard surfaces ofprestressed concrete are simplymore durable and easier to cleanthan metal systems,” says BernardEdstrom, P.E., Senior Civil Engineer,Facilities Engineering, General Mills,Inc. Insulated double tee wall panelsproduce a pleasing balance ofbeauty and quiet strength, whilemeeting the requirements inFlorida’s Energy Code. The designersoftens the building’s mass by usingexposed aggregate in office wallpanels.

SevereMinnesota winter conditions dictateda tight construction schedule and abuilding system weather would notimpede. Precast prestressed concrete met the challenges. “The factory casting of beams, columns andwall panels assured the contractorof delivery schedules and thus aidedthem in coordinating the project,”states Dennis L. Mulvey, A.I.A., project architect. Tolerance to extremeclimate changes and built-in insulation value were functional require

The surprisingly distinctive interiorsof this heavy equipment manufacturing facility prove that standardprecast prestressed concrete components can provide the richnessand variety needed for a strongdesign expression. Rake and smoothfinish hollow core slabs used asexterior walls create a handsomebuilding uncommon to mostindustrial parks. The walls will withstand punishment and remain goodlooking for years. According to thearchitect, prestressed concrete also

The prestressed concrete system proved to be lesscostly and provided a more durableand efficient method of fireprotection than steel.

Energy goal met at minimal costwith precast prestressed concrete

An important consideration in thedesign of this battery plant wasachieving an energy conservationgoal within the limitations of a strictbudget. According to the architect,optimum cost economies resultedfrom using a minimum number ofprecast prestressed concrete components with maximum duplication.The fire resistive components alsoreduced the owner’s insurancecosts. Large overhangs and themass of the roof structure significantly reduced heat gain during

prestressed concretematched only by its economy

Coors Brewing Company Distribution Center, Billings, Montana

The owner of this beer warehousehad to build a facility quickly inorder to meet the deadline fordistribution in a new territory. Thebuilding also had to accomodatefuture growth, maintain their corporate image and stay within a tightbudget. The owner found that standard precast prestressed concretecomponents could be manufacturedand erected in time to meet his

deadline and provide a finishedbuilding that met the estheticrequirements. The versatility ofprecast concrete also allowed theowner to have the corporate logocast into exterior wall panels. Adouble tee roof system providedcolumn-free interior space for theeconomical installation of a 5,500sq. ft. (1680 m2) cooler.
