San Francisco 49ers StadiumClark Pacific

lark Pacific was successful in winning the contract worth $15-$20 million to produce over 2,000 precast pieces for the new San Francisco 49ers stadium. Casting began in April and will be completed early in 2013.

Hamilton Form and Clark Pacific worked closely together to develop a practical and efficient formwork package for theproject. Matt Engleking, the project manager at Clark Pacificnotes, “From the big picture to the smallest detail, the team at Hamilton Form worked with us to help ensure we producea quality product for the long standingrivals of “America’s Team.”

Hamilton Form delivered 260 bed feetof triple and double seating risers forthe project. Forms for higher volumeproducts were made in longer lengthsso that several products could be castsimultaneously. Several sections of tubforms were also delivered. Some willcast both single and double walkways in the same form. Forms for low quantitypieces were configured to accept risers to extend the top of the upperstem so that additional products couldbe cast in the same form.

Some forms were built with magnetic, instead of bolt downrails, to make change overs more efficient.

The forms arrived at Clark Pacific ahead of schedule and readyfor set-up. “The high quality forms fit together perfectly andwere easy to set-up and install in our production plant. Ourcastings look great and we look forward to completing anothersuccessful project with formwork designed and fabricated byHamilton Form,” beamed Matt. (continued inside)

Project Spotlight

San Francisco 49ers stadium(Continued)

he $1.2 billion stadium for the San Francisco 49ers will be located in Santa Clara, California about 35 miles south of San Francisco. It will seat68,500 and have 165 luxury suites and 9,000 premium club seats. Two thirdsof the seats are located in the lower bowl, making it one of the largest lowerbowls in the NFL. The seating capacity can be expanded to 75,000 for special events and will include over 100,000 square feet of flexible meetingspace to further expand its multi-use facility capability.

The stadium is registered with the USGBC under its LEED program. Sustain-ability features include a green roof, solar panels and will use recycled waterfor landscape, toilets and urinals. The building and walkways will be madewith high solar reflectance materials that contain a large percentage of recycledmaterial. The stadium is expected to open for the 2014 NFL football season.

The new 49ers stadium is scheduled to open in 2014.

While the new stadiumis exciting, it’s interest-ing to note some of thehistory of the 49ers oldstadium. CandlestickPark was originallybuilt in 1960 for theSan Francisco Giants. It was the first modernbaseball stadium builtentirely of reinforcedconcrete. Because ofits location on the bay,it was reputed to be thecoldest and windieststadium in the country.It was designed forradiant heat in thedugouts, but pipeswere placed outside,instead of inside theconcrete, so the systemnever really worked.

The Beatles playedtheir last live concertthere in August 1966.In 1971 the 49ersmoved in and sharedthe stadium with theGiants until 1999.

In October of 1989, just before Game 3 ofthe World Series, theLomo Prieta earth-quake struck SanFrancisco. Because ofgame-related sportscoverage, it was thefirst major earthquakein the United States tohave its initial joltbroadcast live on television. The gamewas cancelled for ninedays while the after-math of the earth-quake that killed 63,injured 3,757 andcaused $6 billion indamage was dealtwith. Candlestick Park,however, sustainedonly minor damage.

Today, Candlestick Park is the oldest un-renovated stadiumin the NFL and is destined to be vacatedby the 49ers in 2014.

T

number of bridge and highway construction projects across the country have been keeping many precasters busy. One product often used on highways is soundwalls. Speed Fab-Crete was recently awarded a contract to supply 170,000 square feet ofsound wall panels in varying lengths andheights for an interstate highway in Texas.

To produce the wall panels, two dual batterymolds were built. Each mold casts the wallswith an integral column on one side. The twoforms differ in that one is designed with thecolumn at the top of the mold so that panelsare cast on-edge, while the other mold is configured to cast the product in the as-installed position.

The dual battery mold that casts product on-edge is 42’ long with nominal 13’ high sideforms and 4” soffit. The column is formedby a block-out at the top of the mold, to allowfor production of products up to 21’ tall in a13’ high form. The mold has bolt-on headerson each end and internal headers so that fourproducts can be cast at the same time.

The second mold sets up similar to the first butcasts the product in the as-installed positionwith an integral column at the end of the mold.This mold will cast products that are 13’ highand up to 21’ long. Product lengths can beadjusted with internal headers.

Interior sideforms are fixed in place on a sleepersystem. The outer sideforms are split into two21’ sections that roll back on wheel carriagesand tracks. A catwalk runs between the twointerior sideforms for access to the top of themold. Both under ties and top ties were supplied. The top ties are welded into a singleassembly for each panel cavity for quick installation and removal. Speed Fab-Crete will be installing form liners for a decorative finish on the face of the panels.

Did you know?

Did you know that the Eiffel Tower in Paris is actually six orseven inches taller in the summer than it is in the winter? That’s because the 1,050 foot tower expands when it’s hot andcontracts when it’s cold. Now that summer is here, rememberthis same phenomenon applies to steel beds. And, it’s one ofthe reasons one should always allow for movement wheninstalling long-line steel beds.

A new twist on a stepped form

tubbes Precast in Ontario, Canada came toHamilton Form with a request to build an unusualform. The products are conical with a relief panelon the face. The back of the product is stepped.

After reviewing product drawings, Hamilton Form’sengineers designed an overall form approximately6’ high x 10’ long with a curved base to createthe conical pieces. The form is shaped to produceproducts that change from 4’-10” at the bottomto 7’-7” wide at the top. A raised insert shapesthe relief panel on the face of the product.

A one-piece corded back pan fits over the base. It attaches to headers and an end rail and is heldin place by top ties. Concrete is poured from thetop of the form. The headers, end rail and backpan are pulled away from the base for stripping.
