Doka news

Colorado River BridgeNV & AZ – The multi-year task of connecting Nevada and Arizona with the Mike O'Callaghan-Pat Tillman Memorial Bridge is underway. Also known as the Hoover Dam bridge bypass project, it is the world’s largest concrete arch span bridge. Key segments of this project will utilize Doka’s formwork including Framax, SKE 50 self-raising climbers and Doka’s Top 50 systems.

Bridge remains open during pier cap replacement New York City – The Alexander Hamilton Bridge, which carries eight lanes of traffic over the Harlem River, will be jacked up temporarily. The new concrete structures are formed and supported by Doka’s Staxo 100 load-bearing tower as well as pre-assembled table forms.

Cooling Tower UnderwayMassachusetts – Two natural draft cooling towers are underway for New England’s largest coal-powered generating station in Massachusetts. The project is utilizing SKE self-climbing formwork to construct the towers – the first natural draft cooling towers constructed in the U.S. in more than 14 years.

A flexible handset system was needed to construct the walls on the World Trade Center memorial fountains due to limited crane capacity, and existing structural steel limiting crane access to all areas.

Forming the 9/11 Memorial The National September 11 Memorial will be the nation’s largest man-made waterfall.

Page 4: Aug. 2010 ·  · Paseo bridge Staxo 100 Doka news Colorado River Bridge NV & AZ – The multi-year task of connecting Nevada and Arizona with the Mike O'Callaghan-Pat Tillman Memorial

The two fountains, situated in the footprints of the World Trade towers, are scheduled to open in time for the 10th anniversary of the attacks, next year.

Concrete contractor Navillus Concrete selected Doka’s Frami framed formwork sys-tem to form the 720 ft. of walls on both foun-tains, each fountain spanning 200 ft. x 200 ft. Because of the existing structural steel and the decking that was already in place, form-ing had to be handset for this project.

“Doka’s wall formwork systems were the optimal choice for this significant project because of the flexibility and versatility. Hav-ing a high pour pressure, Frami enabled us

to pour the 21 ft. walls with no problems and only a few ties, essentially saving us time and money. Our guys were able to handset the panels with ease and the results were flawless,” said Jason Roy, General Carpenter Foreman, Navillus Concrete.

The Memorial Jury that selected the design, lead by architects Michael Arad and Peter Walker, state on the 9/11 website, “In its pow-erful, yet simple articulation of the footprints of the Twin Towers, Reflecting Absence has made the voids left by the destruction the primary symbols of our loss. It is a memorial that expresses both the incalculable loss of life and its consoling renewal, a place where all of us come together to remember from

generation to generation.”

In addition to the memorial fountains, Doka provided over 50,000 sq. ft. of Frami and Framax wall formwork to construct the 9/11 museum exhibition. The museum will feature three levels descending below ground and will provide access to the original foundation of the twin towers.

Extending down nearly 70 ft. from the plaza, the Museum is grounded in bedrock. It is here, amidst the foundations of the original World Trade Center complex, that the physical outline and structural remnants of the two towers can still be seen. To the greatest extent possible, the original column bases and con-

crete footings that supported the Twin Towers are exposed in the floor slab of the Museum, defining a clear outline of the Towers.

Doka's wall formwork was used to construct the new concrete exposed walls with Framax Xlife, which provided the smooth architectural finish required. Reaching heights of over 63 ft., Navillus used Doka’s large 2.70 m. x 2.40 m. Framax panels on the exposed side, and Frami with custom aluminum walings on the un-exposed side.

The memorial and museum, which will cost roughly $500 million, will open to the public September 11, 2011.

Working on the World Trade Center memorial, we had architectural

walls and patterns on which only Doka's Framax Xlife could be used. The walls turned out excellent with a very impressive concrete finish.”

Single-source Complete Solution for Speed on SiteWith this overall length and height and a sizeable longitudinal gradient, the Viaducto 5 bridge project is by far the most challenging in the motorway building project GC-2 on Gran Canaria.

To build the 1,312 ft. long Viaducto 5 motorway

bridge, Doka has supplied a comprehensive formwork

solution consisting of cantilever forming travelers,

pierhead formwork and automatic climbing formwork.

August 2010 7The contractor opted for an all-in-one solu-tion from Doka because of the high safety standard of the cantilever forming traveler, the perfect interplay of the formwork and the traveler, as well as Doka’s technically sophisticated solution for constructing the massive pierheads. Short cycle times and safety were key areas of focus for the four bridge piers, each of which is up to 460 ft. tall.

The pre-stressed, single-cell box girder superstructure of the Viaducto De Guia Pagador is being constructed by two pairs of Doka cantilever forming travelers that have been modified to deal with the excess length. In terms of job site safety, the Doka cantilever forming traveler, with its fully railed-in platforms on all work-deck levels and ladderways with built-in ladder cages, is more than meeting the site management’s stringent requirements.

All of the approximately 43 ft. long pierheads are being constructed on a solution based

on main support girders. This involves two parallel steel girders being placed in the longitudinal direction through box-outs in the top casting section of the pier. The steel girders are then crane-lifted into the box-outs and pushed through the piers by a hydraulic cylinder. Next, a girder grill, includ-ing the formwork for the bottom slab of the pierhead, is placed on the main support girders on either side of the pier. After the bottom slab has been cast, the transverse stiffeners, the webs and the deck slab are then cast using Top 50 larger-area formwork elements. Following the completion of the pierhead, the cross girders and the girder grilles can easily be hydraulically lowered and then lifted off the pier.

The two imposing main piers of the Viaducto 5 were constructed using the versatile, high-performing Doka automatic climbing formwork SKE 50. With this system, the site crew was able to form, reinforce and cast the 16.4 ft. high typical sections in a four-day cycle.

The Solution When it came to building the 1,427 ft. long and over 328 ft. tall Viaducto 5 on Gran Canaria, Doka’s highly efficient all-in-one forming package made us the one-stop supplier of choice. Doka delivered an all-in-one forming solution bringing maximum productivity to the in-situ concreting operations. By offering a wide range of services including the formwork planning and logistics management, Doka was able to offer strong support by an experienced Doka Formwork Instructor.

The main piers were built with Doka’s automatic climbing formwork SKE 50 and large-area formwork Top 50 in a four-day cycle.

degrees. The design has unusually shaped walls and fair-faced concrete walls. PCL Constructors Canada Inc. found they needed an actual formwork advisor on the project, not just a supplier.

“Doka provided field personnel to assist in the assembly and execution of the form-work. We found their system was relatively simple to put together and cycle,” said Peter de Rocquiguy, G.S.C. Superintendent, PCL Constructors Canada Inc.

Large-area formwork Top 50 gang panels joined together quickly and suited the different and unusual construction shapes and finish requirements, while saving on costs with on-site assembly. Framed wall formwork Framax Xlife was used for form-ing columns, pilasters and parts of the walls. A combination of both systems was the perfect solution for cores. Framax bias-cut corners in connection with large-area

formwork Top 50 panels made stripping and resetting of the core interior boxes much easier and faster and saved greatly on crane time.

Where formwork support above the ground and wall openings occurred, the Staxo 100 load-bearing towers were used. A combina-tion of Doka MF 240, climbing formwork, and cantilever bracket D22 were used, with high-load capacity anchors and suspension cones, holding the formwork securely onto the concrete. The working platform permits a safe working environment. Shaft platforms were used as safe working decks and form-work support in core shafts.

Climbing 260 ft. High with Doka Formwork The new $245-million Paseo Bridge in Kansas City, Mo., will be a 260 ft. high, dual-span cable-stayed structure across the Missouri River, designed to replace an existing deteriorating 50-year-old bridge.

The Solution The 260 ft. high dual-span

cable-stayed bridge’s most important feature, the bridge

pylon, was possible thanks to the incorporation of Doka’s

formwork systems.

August 2010 11Anchored by a single delta-shaped concrete pylon with legs that will appear to dissolve into the riverbed, the bridge will be a distinctive piece of architecture. Paseo Corridor Constructors selected Doka to provide the engineering solutions and formwork for the top half of the bridge pylon, one of the most important features of the bridge.

Because of the extreme angle of the bridge and pressure of the concrete, significant support was needed to form the pylon. Doka created a customized formwork sys-tem to meet the project’s unique demands. Top 50, which provides easy and efficient forming sequences for large-area projects, was used on the outside face of the bridge pylon, which is inclined at a 20 degree slope with four outside faces. MF 240 support brackets created an 8 ft. working surface and were used on each side of the pylon. D22 dam formwork was used on the short angle faces because of its extraordi-nary load capacity and ability to facilitate

20 ft. tall pours on the 70-degree-inclined pylon. On the sloping side of the bridge pylon, SKE 100, in conjunction with Top 50, was used to support the vertical dead weight of the concrete.

“The use of SKE 100 in conjunction with Top 50 enabled us to cycle much faster than we ever anticipated,” said Dale Hel-mig, Project Manager for Paseo Corridor Constructors. “We found it was exception-ally strong and it effortlessly supported the vertical weight.”

To address the need for worker access on the inside of the pylon, Doka fitted the inte-rior with a custom collapsible steel core and platform, and also recommended the use of guide rollers so the team could roll the formwork up the interior of the shaft after each pour.

Doka’s work on the diamond-shaped pylon began in April 2009 and is scheduled for completion in summer 2010.

Selecting the right formwork can positively affect the project schedule.

August 2010 13CJ Mahan specializes in heavy highway, bridges, treatment plants, and U.S. Army Corp of Engineer projects. Jason Barkhimer, Chief Engineer and Josh Mimna, Project Manager, were inter-viewed about their experience with the Doka Framax Xlife solution.

Q: Why was Framax Xlife a good fit? What needs did it meet for your client(s)? A: Every pour was different with wall thick-ness, height and intersecting wall locations. Framax Xlife was the most flexible system to disassemble and assemble the formwork back into gangs and meet our schedule. We feel that we would not have been able to meet the schedule using another system. Q: How long have you used Framax Xlife? A: We've been successful using the system since 2003. Most recently on the Southerly WWTP, one of our largest Framax projects.

Q: What specific functions does the Framax Xlife system serve for your business? A: It is an extremely flexible system. We have been able to reduce our form and strip costs during projects, which also helps us be more competitive at bid time. Q: Please compare Framax Xlife to oth-er/competitive systems? Why is Framax Xlife the right choice?

A: Framax Xlife provides multiple panel sizes for flexibility, and the stripping corners are a big time-saver. The Doka clamp is much quicker than other systems, the panels are lighter and safety tie-offs are pre-positioned on the panel. In addition, accessories are light, galvanized and easy to use. The galvanized feature and ability to replace the face sheet over time also were important factors. Most other systems cannot provide both of these conditions. Our project tool cost is much lower with this system. Typically a crew only needs a ham-mer to assemble the Framax versus using air tools, compressor and impact wrenches with other systems.

Q: Can you please provide project examples where Framax Xlife was able to meet or exceed your project deadlines or expectations? A: The Southerly WWTP project is a great example. We feel that we would not have been able to meet the schedule with the challenges we faced if we used another system. The stripping corner helped reduce our strip/set time in the tight intersecting wall/corner/pilaster areas of the project. Being able to clamp the gangs together far exceeded the buildup time we’ve experi-enced with other systems. In addition, add-on panels can be quickly attached.

Q: Why would you recommend the Framax Xlife system to other contractors or companies?

Doka Xpress14A: It is quick — a hammer system. No other air tools or accessories are needed and the system is fast, light and manage-able. The panel strut can be adjusted much faster than the typical U.S. style pipe braces, and galvanized accessories keep the product in good working condition for every use.

Q: Describe your experience with Doka and the Framax Xlife system. A: Doka provided the three big things we needed on the Southerly project: good product, good engineering design and sup-port, as well as good service. We were con-stantly experiencing uncontrollable changes to the schedule, which forced us to deviate from our preconstruction plan. The flexibility of the Framax Xlife system helped provide quick decisions and changes so we could adapt to the new design or plan.

Q: What safety features does the Framax Xlife system exhibit for you and your client(s)?A: Tie-off locations are pre-engineered and positioned on each panel, taking the guess work or risk away from not using tie-offs. Other systems have to be attached in the field and there is always a risk that they won’t be used. Also, filler walers and acces-sories can be carried and attached by hand, which reduces our overhead crane work when setting or stripping gangs.

Framax Xlife system provides extreme flexibility with multiple panel sizes, in addition to built-in safety features, and fast assembly.

The Solution With the need to allow water to flow from man-made canals to the open landscape, the Box Culvert Traveler form is ideal. The system is fully rentable and because of its simple design, it is capable of rolling from pour to pour in minutes.

One of the requirements of this project is to allow the water to flow from man-made canals back over the open landscape as it once did. To accomplish this, the use of cast-in-place culverts will be implemented to allow water to flow underneath elevated roads and berms.

In order to achieve the anticipated outcome, a fully rentable Box Culvert Traveler solution comprised of Doka Frami formwork, is al-lowing the contractor to cast the walls and elevated deck as a single-pour concrete shell. The concrete shell is 8 ft. x 8 ft., with casting lengths of 50 ft. per pour.

Southwest Construction Services, Inc. is the concrete contractor for this part of the Florida Everglades Restoration project. They have been highly satisfied to see how fast the culvert is stripped, moved and reset

into position for subsequent pours.

Butch Gilarsky, Superintendent, found the 54 ft. long box culvert easy to set up and move in less than a minute, allowing him to get in, set rebar and prepare for the next pour.

The Everglades Restoration project began in March of 2010 and will include several different restoration projects for completion.

Building on their success in Florida, Doka has already secured a second project in California. With the Box Culvert Traveler’s built-in flexibility, this new project will utilize Framax as the form of choice to construct a 15 ft. wide double barrel box. The system is now jobsite tested, and all details have been worked out to handle a variety of ap-plications.

Pietro Da Sacco, Group Leader, Doka USA, Ltd.

The Factsjobsite Portland, Ore.customer Kiewit Bilfinger Bergerproducts used D22 cantilever system and Frami wall-forming systemtotal Formwork used Almost 2,100 sq. ft. of Frami clamp-style panels were used with 40 D22 cantilever dam brackets and a safe 8 ft. work platform

The Solution Doka engineering worked closely with the contractor to achieve a sequencing plan that not only made each lift easier to climb, but also allowed on-field operators the ease of moving panels with a consistent final finish pattern.

This project involved constructing new shafts for the six-mile-long, 26 ft. diameter East Side CSO tunnel. The 21,500 sq. ft. Taggart shaft serves as a tunnel connec-tion for water overflow, while the 18,000 sq. ft. Port Center shaft and 16,000 sq. ft. McLoughlin shaft serve as the northern and southern ends of the tunnel, respectively.

To accommodate multiple pours at differ-ent heights, contractor Kiewit Bilfinger-Berger used approximately 40 Doka D22 cantilever dam brackets with spindle struts on the bottom slab as starter blocks, and reconfigured for lifts to support almost 2,100 sq. ft. of Frami clamp-style panels in a chorded radius geometry. Doka engi-neering worked closely with the contractor to devise a sequencing plan that made each lift easier to climb and also allowed on-field operators to quickly move panels with a consistent final finish pattern from the bottom of the shaft up to the surface. In addition, 13 ft. high crane lifts with the

D22 cantilever system “rollback” allowed the forms to be easily retracted for clean-ing, oiling, and fitting with leading anchors for the next jump.

The Frami wall-forming system, used by the contractor on a previous phase, provided formwork geometry designed to facilitate changes and to be relocated from lift to lift, all while optimizing labor production. Doka also helped to accelerate the schedule by supplying professional engineering draw-ings to the contractor and the City well in advance of the formwork needs at the site.

“With quality product and site training by Doka field service technicians and use of the Frami wall-forming system, this project put the contractor ahead of schedule and under budget,” said Account Manager Paul Contreras. With the successful installa-tion of the shafts completed, the project is ahead of schedule for its completion date of 2011.

Frami helped to optimize labor production and accelerate the project schedule.

Having the first-ever built-in ladder system, Staxo 100 provides tie off points built into every frame, can be ganged or hand-set, contains integrated couplers with no loose parts and has an optimal load capacity to provide major time and labor savings with a safe working environment.

The concrete had to be cast at a height of 40 ft. with sufficient strength and stability to support the embedded steel. To help meet this goal, contractor F.A Wilhelm Construction chose Doka’s Staxo 100 high-load-bearing tower to support the 4.8 million lbs. of concrete required for the 9 ft. 6 in. thick slab, along with Dokamatic Tables to form 5,600 sq. ft. of slab.

The Staxo 100 load-bearing tower is made of sturdy galvanized steel frames and provides an optimal load capacity of up to 22.5 kip per leg. F.A Wilhelm Construc-tion’s crew found that the shoring system provided quick and easy assembly. “We found the system went up easily and quickly. It poured as solid as anything we’ve ever done. Using this system helped us beat our estimate on the power plant,” said Curtis Arnold, project superintendent with F.A. Wilhelm Construction. Safety was a key concern given the height of this proj-ect and this was assured with the first-ever built-in ladder and OSHA-approved tie-off points.

The preassembled Dokamatic Tables were set on top of the Staxo shoring system to create a 123 ft. long x 40 ft. wide slab pouring area. Optimized for minimal forming times on large deck projects, the system’s fully assembled table form units

quickly position into place and eliminate the need to carry individual components between locations. Using a simple pin connection, Staxo 100 connects directly to the steel stringer of the preassembled table unit and allows flying of a large deck formwork section in combination with the Staxo 100 shor-ing system. This combination allowed 90 percent of the work to be performed on the ground at a safe level. Approximately 218,000 cu. ft. of Doka shoring support al-lowed the team to quickly and easily reach the necessary heights for the remainder of the work.

Doka has optimized a high load value shoring system that performs

with an equally high value production from delivery of equipment to ease of setup to disassembly that simplifies even the most critical safety sensitive projects.”
