Class I Erection Contract up to $500,000: Pedestrian Bridge Project Faces Adversity Similar to an Action Movie Script

Erector: LPR Construction

Fabricator, Engineer and Detailer: Big R Bridge

GC: Kiewit

Contract Value: $308,000

Total Steel Erected: 126 tons 

unspecifiedBefore a 14 ft. x 192 ft. pedestrian bridge was successfully installed over I-225 in Aurora, Colo., the job faced a fire, a car crash, lightning storms and a ticking clock. The bridge connects the Florida RTD Station Platform and Medical Center of Aurora, part of a larger project to extend light rail service to Denver International Airport.

LPR Construction, the steel erection contractor, pre-assembled four sections of the bridge, weighing more than 195,000 pounds each, inside a highway clover leaf, nearly a mile from the construction location. During the pre-build phase someone set fire to equipment parked in the construction zone and later a speeding driver crashed through road barriers, hitting a bridge arch. No damage was found after thorough inspections and the bridge structure was turned over to General Contractor Kiewit.

The second phase, transporting and setting the bridge pieces took place over two nights while the Interstate shut-down to traffic. According to Peter Radice, Senior Project Manager, determining how to set the pieces on trailer dollies and backing the trailer into place required significant pre-planning. LPR worked with Apex Trucking to provide heavy hauling services. A 500-ton Liebherr all-terrain crane rented from RMS Crane was used to lift the bridge pieces. All sections were moved to the permanent location the first night with time to spare. The arches and main truss were scheduled to be set during the second night, but heavy rain and lightning delayed start time by more than three hours. “Lifting the main truss and putting camber back into the arches was the hardest part of the job,” said Radice.

Class II Erection Contract $500,000 to $1 million: Perfect Sequencing, Creative Ironworker Positioning Secret to Modern Day Pyramid Completion

Erector: Gabriel Steel Erectors Inc.

Fabricator: Orange County Ironworks LLC

Detailer: KVD Detailers

GC: Hunter Roberts

Total Steel Erected: 200 tons in Top of House (500 tons total)

unspecified-1Sister companies Orange County Ironworks and Gabriel Steel Erectors, based in Montgomery, N.Y., were privileged to play an integral role in the fabrication and steel erection of one of Manhattan’s newest residential high rises. Appearing on the skyline like a half pyramid, the VIA Building on West 57th Street, was recently named winner of the Best Tall Building Americas by the Council on Tall Buildings and Urban Habitat. The 34 story building houses more than 700 rental units and 45,000 sq. ft. of retail space. Lots of natural light and spectacular views are made possible by the unusual shape.

The shape presented challenges for the fabricator and erector team. “Most structures are built on a grid pattern. This building was X, Y, and Z coordinates. Each piece of steel had to be sequenced exactly, or it would negatively impact the placement of the next piece of steel,” said Matthew Messing, who is Senior VP of Operations for both Orange County Ironworks and Gabriel Steel Erectors. “We used a 3D erecting plan to pre-design every piece in order,” said Messing. The steel was lifted with a Favelle Favco M220D luffing tower crane. In addition, significant coordination was required with mechanical contractors during construction in order to interface the façade of the building with integral window washing and exterior building maintenance systems.

The biggest challenge came as the building reached its peak. Extending 10 more floors above the occupied space is the tip of the pyramid, which Messing refers to as the Top of the House. This portion of the job alone required 200 tons of steel. No floors existed in the all steel frame, so Gabriel Steel had to build temporary flooring in order to give Ironworkers access. Because space was so tight, Gabriel Steel used a unique aerial lift solution to position Ironworkers for connecting and bolting. The company rented a Teupen Leo23GT and Leo 18GT from United Rentals. The lift is ideal for setting up in as little space as possible, with variable position stabilizers, rotating basket, and articulating and telescoping boom.

“This project presented challenges on every level, from detailing to engineering to coordination, fabrication, trucking, logistics, and erecting,” said Messing. “It was the combined effort of a tremendous team of individuals working on all these aspects that led to the success of the project.”

Class III Erection Contract over $1 million to $2.5 million: Small Steel Sequences Provide Solution to Tight Job Site

Erector: CSE Inc.

Structural Engineer: Fox & Associates

Fabricator: Lynchburg Steel & Specialty

Detailer: Virtual Steel Technologies Inc.

GC: CMA

Contract Value: $2.3 million

Total Steel Erected: 1,072 tons

unspecified-2A new School of Music for Liberty University’s Fine Arts department in Lynchburg, Va., was completed ahead of time and under budget due to close collaboration between CSE Inc., the steel erection contractor, and local steel fabricator, Lynchburg Steel & Specialty.

Two buildings housing a 1,600-seat auditorium and concert hall and four-story educational center with practice studios, the new School of Music is part of a larger $500 million campus rebuilding campaign. The job site was pinned in by train tracks on one side, adjacent structures, and a single access road on another side. For this reason, there was no room to stage iron for steel erection. “There was barely enough room to set up a crane,” said Ronnie Ranson, Vice President of Steel Erection. Instead, CSE worked with Lynchburg Steel to deliver small sequences of steel. “The ability to work with a local fabricator was the only way to cost-effectively accommodate the complicated steel schedule,” said Ranson. In addition, months of erection time was eliminated from the schedule by pre-fabricating the seating at Lynchburg’s shop, rather than erecting on site.

Two other interesting aspects of the project included the design of the roof connection and the practical use of catwalk frames. Designed for optimum acoustics, the concert hall roof is a semi-circle with a step down conical shape. Structural framing consisted of four 100 ft. long trusses weighing up to 20 tons each. Arranged in a spoke formation, the trusses were attached at a single connection point with more than 120 bolts. Lift plans for placing the trusses with a 350-ton Grove all-terrain crane and Manitowoc 888 crawler crane were designed using 3D Lift Plan.

In addition, limited floor access meant aerial work platforms could not be used to install hundreds of feet of catwalks, which house Audio/Visual equipment. Once again, CSE relied on the fabricator to prefabricate the catwalk frames so they could be lifted into place as complete units. Later other trades the catwalks in place of AWPs to install the A/V equipment.

Class IV Erection Contract over $2.5 million: Full Court Press Delivers Winning Strategy for Ole Miss Basketball Arena

Erector: Bracken Construction Co., Inc.

Structural Engineer: AECOM Design

Fabricator: Steel Service Corp.

Detailer: MMW Inc.

GC: B.L. Harbert International

Contract Value: $3.7 million

Total Steel Erected: 2,700 tons

unspecified-3The University of Mississippi broke ground on a new basketball arena, part of a larger university expansion project, in July 2014. Contractors were given just 16 months to complete The Pavilion, a multi-purpose facility with an arena that seats 9,500 people. In order to be ready for the 2016 basketball season, contractors had to maintain a full court press throughout construction. Bracken Construction, the steel erection contractor, did their part by completing steel and pre-cast erection in just 21 weeks.

The three-story arena’s structural steel frame features a barrel rolled steel truss roof system.

The curved roof, constructed of eight main trusses, supports a roof that covers the 230,000 sq. ft. arena. The main trusses each weighed 60 tons. With only one access road available to construction traffic and laydown space at a premium, steel erection contractor Bracken Construction devised an efficient method for truss construction.

Using the bowl of the stadium, which was only 90 feet wide, each truss was delivered to the site in pieces for field assembly. Once assembled in a vertical plane, the three truss sections were hung in place separately and connected in the air at each splice point. The two end sections were lifted into place using two 300-ton crawler cranes set up on each side of the arena bowl, and one 200-ton crawler inside the bowl to erect the center section. “It took some creative thinking to figure out how to erect the trusses to the proper elevation and set the camber,” said Ben Wadlington, CEO, who said this was the first time in the company’s 60-year history that it hung trusses in this way.

In all, Bracken placed 6,835 pieces of structural steel and 422 pieces of structural and architectural precast, finishing ahead of schedule, demonstrating their ability to manage the Xs and Os of the game plan.

Baby & GTraditionally August is hot, humid, the vacation month, the yellow-cone-traffic-jamb-detour season; long weekends; yard work; painting; planning; fixing. It’s a busy time for everyone especially the construction industry. Is it as busy as it should be; needs to be?

By this time we know who is running for the presidency and what they are saying they will do. It’s not only the presidential who are trying to convince us they are what we needs it’s also people running for congress the house and the senate.

I recently received a press release from the Associated Builder and Contractors, ABC, which I would normally have run as a new item but because November is approaching faster than the end of summer I thought I’d share it with you now.

Construction Labor Force Shrinks, Job Numbers Flat

Labor Market Dynamics Cause for Concern

Despite a broader U.S. labor market rebound in June, the construction industry failed to add jobs for a third consecutive month, according to an analysis of today’s U.S. Bureau of Labor Statistics report by Associated Builders and Contractors (ABC). The construction industry’s employment level remained essentially unchanged in June.  

While nonresidential specialty trade contractors collectively added 3,700 net new positions, nonresidential builders shed 1,300 positions, and heavy and civil engineering contractors reduced staffing levels by another 3,900. Residential builders trimmed their employment total by 2,400 in June, while residential specialty trade contractors added 4,700 positions. 

“The construction industry unemployment rate declined to 4.6 percent in June from 5.2 percent the previous month, but not for the right reasons,” said Anirban Basu, ABC’s chief economist. “The overall national unemployment rate rose in June as labor force participation edged higher. However, the size of the construction industry labor force shrank. This may be an indication that as other segments of the U.S. economy continue to add jobs, a growing number of construction workers and construction jobseekers are shifting to other industries.  There are many implications associated with this pattern, including relatively faster wage growth despite the recent flattening in nonresidential construction spending. 

“As has been the case for many months, the most significant sources of weakness in construction activity and hiring relate to public spending,” said Basu. “Despite the passage of a federal highway spending bill late last year, heavy and civil engineering contractors, many of whom are engaged in work on roads and bridges, have been trimming employment. Not only did this segment shed jobs in June, but employment in this sector is slightly less than it was a year ago.

“The Bureau of Labor Statistics reported this morning that the nation added 287,000 net new jobs in June, led by job growth in leisure, healthcare, professional/business services, retail and finance. The information sector also added jobs as striking Verizon workers returned to work. Given the recent rise in oil prices, construction industry stakeholders may be speculating that some workers may have left the industry for the energy production sector,” said Basu

Employment_7_8_16 Employment_Chart 2 7_8_16There are only days left until the election. The presidential election is important but so are all the elections. Take time to understand what the representatives you vote for stand for; believe in; support.

Our highways and infrastructure are crumbling; we need people in congress who understand the importance of updating, repairing, replacing and maintaining these resources.

In November VOTE, but vote intelligently.

DEWALT’s New Batteries & Tools Improve Job-site Safety and Productivity

DEWALT’s new FLEXVOLT system brings the concept of a cordless, hose-less jobsite closer to realization and reality than ever.

DCB606_8The recently unveiled the FLEXVOLT™ system, which features the world’s first battery that automatically changes voltage when the user changes tools does just that plus. The FLEXVOLT™ battery powers a new lineup of brushless 60V MAX* and 120V MAX* FLEXVOLT™ tools. What makes the FLEXVOLT™ battery (DCB606) extremely innovative is its patent-pending technology that is backwards compatible with most existing DEWALT 20V MAX* tools and chargers. When used in DEWALT 20V MAX* tools, the FLEXVOLT™ battery provides up to 4X runtime**. In addition, the FLEXVOLT™ battery provides more than 3X battery power versus DEWALT 18V NiCad.

 

The key to this technology is the ability of the FLEXVOLT™ battery to switch between DEWALT tools of varying voltages (20V MAX*, 60V MAX* and 120V MAX*). The FLEXVOLT™ battery automatically changes voltage depending on whether it’s being used in a 20V MAX* or 60V MAX* tool. Two FLEXVOLT™ batteries together power the new DEWALT 120V MAX* tools. This means that high power tool applications that previously could only be accomplished by corded tools, can now be performed with the DEWALT FLEXVOLT™ system of cordless tools. As a result of this advanced battery technology, jobsites can now fully transition from corded to the freedom of cordless.

The FLEXVOLT™ battery not only extends the runtime of existing DEWALT 20V MAX* tools, but it also powers five new 60V MAX* tools and two new 120V MAX* tools (with 2 FLEXVOLT™ batteries). The new 60V MAX* FLEXVOLT™ brushless tools include a 7-1/4” Circular Saw (DCS575), 4-1/2”-6” Grinder (DCG414), Reciprocating Saw (DCS388), 1/2″ VSR Stud and Joist Drill (DCD460), and 8-1/4” Table Saw (DCS7485). The new 120V MAX* FLEXVOLT™ tools are a 12” Fixed Head Compound Miter Saw (DHS716) and 12” Sliding Compound Miter Saw (DHS790).

Frank Mannarino, President of Professional Products Group said, “The impact of the FLEXVOLT™ system will be felt throughout the construction industry on each and every jobsite. This new platform packs the power required for heavy-duty applications, makes it easy to exchange corded tools for cordless, and ensures that our existing 20V MAX* users get the benefit of added runtime without making the 20V MAX* system obsolete.”

Also capable of operating off of the FLEXVOLT™ battery platform are new 20V MAX* tools, including a Portable Power Station (DCB1800), 20V MAX* Bluetooth® Radio Charger (DCR025) and 20V MAX* Bluetooth® LED Area Light (DCL070). DEWALT’s 20V MAX* Hammer Drill & Impact Driver Combination Kit (DCK299) will also be offered kitted with a FLEXVOLT™ battery in addition to a 2.0 Ah Pack. In addition to the tools, FLEXVOLT™ High Efficiency Accessories™ are Engineered to Maximize Runtime™. This new line is optimized for use with cordless power tools and is engineered to deliver more cuts or holes per charge than standard DEWALT accessories.

DEWALT continues to develop tools that provide more power and runtime, and combined with FLEXVOLT™ battery technology, completely cordless jobsites are within reach. Without the hassle of cords or generators, cordless tools now have the runtime and power needed to complete almost any construction task. Available in fall 2016 where DEWALT products are sold, each FLEXVOLT™ tool comes with the standard DEWALT 3 year limited warranty, 1 year free service, and 90 day money back guarantee while the FLEXVOLT™ battery comes with a 3 year limited warranty, 3 year free service, and 90 day money back guarantee.
