Employers Mutual Casualty Company, Des Moines, Iowa

An innovative guided rail system and light wall formwork gave the contractor an edge.

EMC Building

The Employers Mutual Casualty Company (EMC) 8th Street four-story office building in downtown Des Moines includes below-ground parking, conference rooEMC Buildingms, and a wellness center. A skywalk concourse will connect the new building with an existing EMC building. Concrete contractor, Neumann Brothers, worked with EFCO, which supplied the formwork.

Starting off the project, Neumann used plate girder forms for all of the large footings and the tower crane slab. Once this was complete, Neumann turned to lighter-weight forming system to handle the foundation walls.

Twelve-foot-tall round column forms with diameters of 24 inches and 30 inches were used in the basement. The two-piece column form with high-strength connection bolts only on 2-foot centers and a split washer provided a labor-saving benefit for setting and stripping the entire form with one pick of the crane. Tight precision face sheet joints minimized offsets and grout leakage while delivering a quality concrete finish.

Neumann used EFCO’s guided rail system (GRS) and light wall formwork to build the elevator shaft for this new building. The GRS is designed for safety and efficiency, which starts during assembly and continues through installation and all the way up the structure. The GRS gangs are assembled on the ground installing work decks and preparing the form rollback systems. The built-in rails of each gang remain attached to shoes installed on previous pours, allowing a crane to lift the setup while continuously attached to the wall. Gangs can be lifted and set for the next pour in minutes.

The GRS was installed on the core after the first 13-foot-tall pour was complete. The integrated roll-back assembly on the GRS frame allows the formwork to move back 30 inches providing easy access to formwork and clearance for rebar installation. The CAM Rollers provide smooth operation, and the formwork can be pushed back and forth by operators alone. The system also includes a ratchet for mechanically retracting the roll-back in windy conditions or large formwork gangs. Using the roll-back feature on the GRS, the iron workers were able to complete their work where they positioned rebar, block outs, embeds, ties, and anchors for the forms. Developing this plan in advance, the Neumann and EFCO engineering teams made this project a success.

The contractor used a shoring system to form the 19,000-square-foot first floor deck. The waffle slab design for the first floor has variable slab depths of 2 feet, 2 feet 6 inches, and 3 feet along with several elevation changes. Neumann used modular deck shoring towers with long and short jacks to account for the change in elevation and sloping floor support. The shore towers supported contractor-supplied steel tubs to form the pan deck design.

The project is expected to be completed in early 2017.

 NEW PHASE OF RAIL CONSTRUCTION KICKS OFF IN 2016

Published: Wednesday, January 6th 2016, 2:33 pm CST

HONOLULU (HawaiiNewsNow) –

PEARL HIGHLANDS ELEVATED RAIL STATIONThe new year means a new phase of rail construction on Oahu.

After completing the first five miles of the 20-mile fixed guideway, construction of the elevated rail guideway is now entering the Pearl City area along Kamehameha Highway fronting the Pearl Highlands Shopping Center.

The concrete segments will be placed along existing columns along the 4-mile route to Aiea throughout the year.

Column work continues along the route in advance of the guideway segments.

Work continues in the Waipahu area this year as crews continue to set the guideway and columns along Farrington Highway towards Pearl City.

Crews are building the line from both the Ewa and Pearl City directions in hopes of completing the work this year. The new guideway work along Kamehameha Highway is the most visible of the new rail work this year.

So what else should residents expect to take place with rail construction and activities in 2016?

Rail officials said they are working to connect the guideway on both ends of the segment that stretches over the H-1 freeway near the H1-H2 merge to its respective Waipahu and Pearl City lines this year.

Additionally, work is expected to be completed on the 43-acre Rail Operations Center located near Leeward Community College, which is currently 90 percent complete.

Within the next few months, the first two rail cars will arrive in Honolulu from California and officials added that they also plan to break ground during this time on the first of the 21 rail stations, beginning with the Farrington Highway Station Group which includes the West Loch, Waipahu Transit Center, and Leeward Community College stations.

Officials said the second balanced cantilever construction will also get underway soon as crews start to build the line over the H-1 Freeway near the Sears Distribution Center.

And finally, new rail construction could begin in the Kalihi, Airport and Makalapa areas this year according to Honolulu City Councilman Joey Manahan, chairman of the Transportation Committee.

He said officials with the Honolulu Rail Transit Authority (HART) have indicated to him that they hope to start construction on the line along Dillingham Boulevard this year, possibly as early as June.

Manahan added that construction work in the airport and Makalapa areas is also on their radar to commence this year.

Manahan is asking HART officials to provide the Transportation Committee with the latest construction update in a meeting on January 15.

DOWNTOWN DENVER’S LARGEST PROJECT – UPDATE #13

Denver Update 13

1144 Fifteenth Street is starting to make a huge impact along 15th Street. Since our last update in June, the tower crane has been jumped, the core is climbing its way up onto the skyline, and the parking structure is almost topped out. Let’s take a look!

The parking garage is now up nine stories with only three more to go. Once the concrete structure of the garage tops out, the steel structure will begin for floors 13 through 40; 42 with the mechanical penthouse.

The transformation of 15th Street is a fantastic sight. It’s amazing what three buildings (Le Meridien / AC, aLoft, 1144 Fifteenth) can do to a streetscape.


CONSTRUCTION OF THE LARGEST LAND-BASED WIND TURBINE EVER BUILT IN THE UNITED STATES USING EFCO FORMS

“Reaching New Heights” uses a combination of time-lapse footage, aerial photography and behind-the-scenes action shots to document the steps involved in building MidAmerican Energy’s first concrete wind turbine tower, located at the company’s Adams wind farm in Adams County, Iowa. At 379 feet from ground to hub, the concrete turbine is more than 100 feet taller than its neighboring turbines constructed with steel towers.

DOWNTOWN DENVER’S LARGEST PROJECT – UPDATE #11

Denver Update 1140 STORY, 603-FOOT TALL TOWER

1144 Fifteenth is in a very exciting stage right now with the core starting to quickly go vertical. When we last visited this site, we noted that the core was out of the ground and starting to climb. To kick off the week, we are going to check out the progress of 1144 Fifteenth from both above and street-level vantage points.

The lobby level and ramps for the above ground parking deck are currently underway along Arapahoe Street. It doesn’t appear that a precast system will be used which means each parking level will have concrete pours like what we saw with 1401 Lawrence back in June.

40 STORY, 603-FOOT TALL TOWER

Goodbye hole in the ground, hello rising core! Downtown Denver’s largest project is officially out of the ground.

Watching a project like 1144 Fifteenth Street is quite the journey. From the ground-breaking ceremony to watching giant foundation piers go down over 100 feet and needing aerial coverage for peeking in the hole, we can finally see this 40-story, 603-foot tall tower rise from the street.

EFCO’S HELPING MIDAMERICAN REACH HIGHER ALTITUDE


MidAmerican Energy says it’s building the tallest land-based wind turbine in the nation in southern Iowa. The Des Moines-based power company will get the added height by building the wind turbine tower from concrete instead of steel, a first for the company. The extra 100-plus feet enables the turbine to capture more wind energy, the utility said.
