WasteExpo 2014 is hosting two training workshops on April 30, 2014, from 8 a.m. to 5 p.m. at the Georgia World Congress Center in Atlanta in conjunction with the convention. The Construction & Demolition Waste Recycling Training is offered by WasteCap Resource Solution, Milwaukee, Wis. It also will offer a Deconstruction Training Course in conjuntion with the Building Materials Reuse Association, Chicago.
WasteCap lists the objectives and benefits of the Construction & Demolition Waste Recycling Training as follows:
WasteCap Resource Solutions has more than twelve years of experience in training building professionals on reuse and recycling of materials. WasteCap developed this U.S. Green Building Council approved training in 2005 as part of its mission to transform waste into resources. The day-long C&D waste recycling workshop is designed for attendees to learn the necessary skills to develop, manage, monitor, document and promote a successful recycling program for construction and demolition debris.
Participants will receive a three year Accreditation in Construction Waste Recycling. LEED Accredited Professionals (APs) and Green Associates are eligible for 7.5 Continuing Education Units through Green Building Certification Institute (GBCI). Additionally, architects are eligible for 7.5 Learning Units through American Institute of Architects(AIA) .

WasteCap has more than twelve years of experience in training building professionals on reuse and recycling of materials. The BMRA provides increasing opportunities for the recovery and reuse of building materials in an environmentally sound and financially sustainable way. Attendees will learn the necessary skills to develop, manage, monitor, document and promote a successful deconstruction project and take away the eight steps to create and manage a successful project from beginning to end, says WasteCap.

Construction employers added 19,000 workers to payrolls in March 2014, bringing industry employment to the highest level since June 2009, while the industry's unemployment rate dropped to the lowest March level in seven years, according to an analysis of new government data by the Associated General Contractors of America (AGC), Arlington, Va. AGC officials warned that the pool of available workers is declining rapidly, raising the prospects for significant labor shortages if demand continues to expand.
"The rate of construction hiring continues to outrun job growth in the overall economy for the past year," says Ken Simonson, AGC chief economist. "Furthermore, the pickup has been well balanced, as both nonresidential and residential construction segments added workers last month and over the past 12 months."
Construction employment totaled 5,964,000 in March, a gain of 151,000 or 2.6 percent from a year earlier, compared with a rise in total nonfarm employment of 1.7 percent over that period, Simonson noted. Residential building and specialty trade contractors added a combined total of 9,100 workers in March and 103,000 (4.8 percent) over 12 months. Nonresidential construction—building, specialty trades and heavy and civil engineering contractors—grew by 9,900 employees last month and 48,800 (1.3 percent) since March 2013.
"Although most construction employers who need workers have been able to find them so far, increasing numbers of contractors say they are having difficulty hiring," Simonson warns. "Last month, the number of unemployed former construction workers fell to the lowest March level since 2007. More of these experienced workers are leaving the industry than are rejoining it."
The unemployment rate for workers actively looking for jobs and last employed in construction declined from 14.7 percent a year earlier to 11.3 percent last month. Simonson noted that the unemployment rate for construction workers had fallen by more than half since March 2010, when it reached 24.9 percent. During that time, the number of unemployed workers who last worked in construction declined by 1.3 million, but industry employment increased by only 445,000.
"Based on projects that have been announced in recent months, contractors are likely to be seeking workers for many types of construction in most parts of the country this spring," Simonson adds. "Multifamily, manufacturing and oil and gas-related facilities will generate particularly strong demand for workers. It will be a challenge to fill all the openings."
AGC officials say one reason the industry is likely to face labor shortages is because of the declining number of secondary-level construction training programs. They urge federal, state and local officials to take steps designed to make it easier for schools, construction firms and local trade associations to establish new training programs for future construction workers.
"If elected and appointed officials don't act soon to improve the quantity and quality of training opportunities for future workers, many firms are going to have a hard time keeping up with demand," says Stephen E. Sandherr, the association's chief executive officer. "The last thing the economy needs is to have labor shortages undermine the construction industry's long hoped-for recovery."
Peoria, Ill.-based Caterpillar Work Tools, a leading provider of excavator and wheel loader attachments, is introducing a new generation of multi-processors (MPs) for Cat hydraulic excavators. The Cat MP318 and MP324 MPs can handle most any demolition job simply by using the basic housing and a choice of up to six available jaw sets, the company says.
The new MP design builds on the success of its predecessor. According to Caterpillar, it features an efficient weight-to-power ratio and an incredibly strong cutting and crushing capability. The rotator provides a continuous 360-degree rotation that allows the operator to carry out the demolition job quickly and precisely from any angle, the company adds.
Each MP can be equipped with a wide selection of interchangeable jaws: concrete cutter (CC), demolition (D), pulverizer (P), shear (S), universal (U) and tank shear (TS). With one common housing and properly selected sets of jaws, a contractor can achieve flexibility with minimum investment and can accomplish most tasks encountered on a demolition job. The various jaws can be quickly installed or changed, thanks to a new patent pending jaw locking system, the company says. Instead of taking about 45 minutes to change the jaws with the previous series, Caterpillar says it now takes 10 minutes using basic tools.
Caterpillar says it has made maintenance easier, too. The new jaws use bolt-on and pin-on wear material to eliminate almost all need to weld the jaws. Protection for hydraulic components and hoses has been increased, and an improved motor guard gives greater motor protection. Caterpillar adds that access to the cylinder has been made easier and the cylinder rod protection has been optimized. To ease servicing, the number of greasing points has been reduced on the multi-processors, and daily maintenance requires only greasing, checking wear and replacing any worn parts.
With the release of the new MPs, six new jaw sets have been designed to take on any demolition job:
Company Wrench Ltd., a Carroll, Ohio-based specialty equipment sales, rental, parts and service company with 13 locations in the U.S., has partnered with Kocurek Excavators Ltd., Ipswich, United Kingdom. According to Company Wrench, the exclusive Kocurek dealership agreement will allow it to expand its products and services deeper into the demolition market segment in the U.S. and Canada.
Company Wrench has its own fabrication and manufacturing facility in CW Machine Worx Ltd., based in Carroll. In recent years, the company says the facility has been inundated with orders for producing custom fabricated products, high-reach machines, long-reach machines, cab extensions, auto dismantlers and other specialty equipment for Company Wrench, as well as completing customer machine modifications and custom high-reach machines for its specialty demolition customers.
Kocurek Excavators Ltd. says it was looking for the right partner to take its high-reach and long-reach fronts into the North American market. Brian Carroll, Kocurek general manager, says, “The timing of this agreement is perfect. The U.S. has been very slow to adopt high-reach demolition equipment that is standard equipment here in Europe. But having been pioneered by a few forward-thinking contractors, the concept is really starting to gain momentum in the US. And with its long history of supplying the U.S. demolition sector, Company Wrench is ideally placed to take maximum advantage of that market potential.”
