architectural and structural precastconcrete to provide exceptionalaesthetics and performance.
Total precast parking design in-cludes components that are typi-cally produced in precast concrete,such as columns, beams, invertedtee beams, load bearing spandrelsand double tees. Precast can alsobe used for elements that might oth-erwise be constructed in cast-in-place concrete, steel or masonry, in-cluding bridge elements, elevatortowers, stairs, landings, railings,parapets, and shear walls.
Benefits of TotalPrecast:
SPEED As casting is com-pleted at the plant, the building sitecan be simultaneously graded andprepared. With precast you will seeshortened construction time, accel-erated schedules and earlier rev-enue recognition.
AESTHETICS By integratingarchitecture directly into our struc-tural system, you are offered an un-limited variety of design choicessuch as colors, textures, veneers,all supported by a resilient structuraldesign.
COST While first costs arecompetitive with competing designsand systems, a total precast parkingstructure’s shortened constructiontime and long-term durability resultin increased efficiency and evengreater owner value.
PERFORMANCE Our uniqueprecast systems are designed notonly for exceptional aesthetics andcost effective construction, but also
for seismic resilience, meetingCalifornia’s stringent building coderequirements and, with the PrecastHybrid Moment Frame, offering anowner access to something not cov-ered by existing codes – an oppor-tunity to not only preserve life andlimb, but to limit damage to thestructure itself.
As experts in parking and theleading source for precast concreteinnovation and performance, ClarkPacific will provide you with anentire package for design-buildparking structures. The company’sunique approach ensures turnkeyresponsibility and accuracy formeeting design specifications anddelivering results.
Owners, developers, architectsand contractors all benefit fromusing precast, prestressed concretecomponents to design and buildparking structures. Throughout thecountry, thousands of precast struc-tures are parking millions of cars,with some of the largest structuresever built being created from pre-cast design. A Few Reasons Why:
ENVIRONMENTALFRIENDLINESS
As communities demand moreopen green space around develop-ments and concerns rise over waterconservation, the need grows formore tiered parking. Precast con-crete components address thesedemands in a cost-efficient way thatfits perfectly with tight construction
timetables and budgets, all whileminimizing the impact on the sur-rounding environment.
SAFETY & SECURITY
The use of new framing tech-niques helps designers create light,bright interiors that can completelyeliminate shadowy spaces, thus in-creasing intrinsic security for users.
AESTHETIC VARIATION
Precast concrete can be used tomimic a variety of much more costlyfacing materials, including lime-stone, sandstone, brick and terracotta. This allows the structure tomore readily and cost-effectivelyblend with its neighborhood, ifneeded. The addition of decorativedetails can add visual interest andreduce the structure’s visual mass,creating a community-friendly facil-ity.
FAST CONSTRUCTION
Precast’s ability to begin castingprior to and during foundation andsite work speeds up constructionand reduces the amount of on-sitelabor required for the project.
DESIGN FLEXIBILITY
Precast concrete offers long,clear spans and compressionstrengths far above typical expecta-tions. Coupled with Clark Pacific’sPrecast Hybrid Moment Frame sys-tem, parking structures (especiallythose designed for essential serv-ices) can meet and exceed seismiccode requirements, and are de-signed for immediate re-occupancyafter seismic events. These precastbenefits accrue to parking struc-tures of all sizes and locations.
QUALITY CONTROL
Clark Pacific is a PCI-certifiedplant and we adhere to the compre-hensive quality control procedures.An added benefit of precast con-struction is the inherent increaseddurability that minimizes the needfor continuous on-site inspectionsand costly long-term maintenance.Thanks to Clark Pacific for theabove article.

New Design Guidelines for Precast Concrete Parking Garages ... an article by BergerABAM
When driving to any urban city, a typical concern iswhere to park your car when you get there. Fortunately,many options abound in the form of precast concreteparking garages. Built solely for the purpose of automo-bile parking, these multi-level structures present manyfactors that must be considered by the engineer re-
sponsible for their design, such as safety, efficiency,and the economic aspect during construction.
To keep up with the rapid growth of urban areas, en-gineers must also seek ways to improve the designprocess through simplification so that parking garagescan be built with greater speed and efficiency, but withconsistent accuracy and quality.
Catrina Walter, a civil engineer with BergerABAM’soffshore group at the Federal Way office, recently com-pleted a research program to develop new designguidelines that are already being followed by designersand precasters to build parking garages, as mentionedabove, faster and more economically than before, butwith the same safety standards. With four colleagues,she began her research while studying for her master’sin civil engineering at North Carolina State Universityand co-authored a two-part paper that details the re-sults of final reports from her research.

Dailey Precast, LLC of Shaftsbury, VT recently sup-plied all precast structural and architectural compo-nents for a new three-level parking structure to serve anew manufacturing plant addition for the growing CubistPharmaceuticals company. In addition to the typicalparking deck components (double tees, beams,columns, spandrels, etc), included in Dailey's workwere two stair towers and an elevator well, plus thestriking pedestrian bridge between the new parkingstructure and the new manufacturing plant addition.
The very tight site presented several logistic chal-lenges. There is a protected wetland to the north of thework which had to be protected; the site allowed limitedaccess around the structure; there was no room for a
staging area for product or equipment; access to thenew work was through a heavily-used active parkingarea, with only a very narrow entrance and exit road.Obviously, this required complete careful traffic controland carefully timed loads to the crane hook – for everypiece!

Experimental Results” was published in the spring 2011issue of the PCI Journal and, as the title suggests, fo-cuses on precast concrete slender spandrel beams,vital structural members of parking garages. Catrina ex-plains that the primary purpose of these beams is totransfer vertical loads from deck sections (the area ofthe garage on which your car sits) to columns in orderto transfer loads safely to the foundation. She furtherexplains that spandrel beams often serve as railings orbarriers around the exterior edge of a parking structureusually as half-height walls that prevent cars from driv-ing over the edge.
To gain a better understanding of the primary role ofslender spandrel beams, Catrina provided an explana-tion of loading. Consider the double tees that usuallymake up the floor of parking garages and typically span40 to 60 feet. Each end of a double tee is placed on theledge of a spandrel beam; this is how the spandrelbeams are loaded. Your car sits on the deck of the dou-ble tee and the double tee transfers the load from yourcar to its supported ends. Each stem from the doubletee then loads the ledge of the spandrel beam as indi-
vidual point loads. The spandrel beam then transfersthe load to the column and the column then transfersthe load into the ground.
Catrina made it clear that this project was not at allabout failure of current spandrel beams. Current slen-der spandrel beams were actually overly reinforcedand, therefore, were not as cost effective as they couldbe, although they were as safe then as they are nowwith the new design guidelines in place. She goes on toexplain that during the research project, the full-scalespandrel beam specimens were overloaded until theyfailed so that the failure mechanism could be identified.Spandrels would not be loaded to such an extreme de-gree in a real-life situation.
While the experimental results of the research weredetailed in Part 1 of the paper, Part 2, “Development ofa Rational Design Methodology for Precast ConcreteSlender Spandrel Beams: Part 2, Analysis and DesignGuidelines,” details the analysis and resulting designguidelines and was published in the fall 2011 issue ofthe PCI Journal.
