CASE Expands D Series with CX145D SR Minimum-Swing Excavator

New 32,100-pound minimum-swing excavator offers reduced footprint, precision maneuverability and powerful bucket digging force and lift capacity for road and bridge work, utility, landscaping and general construction applications.

CASE Construction Equipment introduces the all-new CX145D SR minimum-swing radius excavator to its D Series lineup. Designed to provide ample digging and lifting power in a small footprint, the CX145D SR features a compact counterweight and modified boom placement. This results in a highly maneuverable and powerful excavator that is easy to transport and ideal for restricted jobsite conditions, such as road and bridge work, utilities, urban construction and landscaping applications.

With an operating weight of 32,100 pounds and a 102 HP Tier 4 Final engine, the CX145D SR offers bucket digging forces up to 21,400 foot-pounds and lift capacities up to 21,350 pounds. Options include a dozer blade configuration as well as the choice between either steel or rubber tracks depending on operating conditions and jobsite requirements.

Each D Series model is built to provide significant operational gains, including faster cycle times, improved responsiveness and greater fuel efficiency. An electronically controlled hydraulic pump and larger control and solenoid valves increase lifting capacities and improve responsiveness.

D Series models offer more standard features than previous CASE excavators, simplifying the buying process and making them extremely versatile and operator friendly. All CASE D Series excavators provide peace of mind and lower total cost of ownership through CASE ProCare™.

Maintenance-free Tier 4 Solution

The CASE CX145D SR excavator meets Tier 4 Final emissions standards through an innovative combination of selective catalytic reduction (SCR), cooled gas exhaust recirculation (CEGR) and diesel oxidation catalyst (DOC) technologies, which helps maximize uptime and performance – all with minimal maintenance. There is no diesel particulate filter (DPF), no DPF regeneration or associated lifetime service costs.

 Intelligent Speed, Power and Efficiency

Faster cycle times are achieved through a new electronically controlled pump, a larger control valve and multiple sensors. These features enhance the CASE Intelligent Hydraulic System and its four integrated control systems to make the best use of the machine’s hydraulic power and momentum, resulting in added strength and fuel efficiency.
The four systems that make up the CASE Intelligent Hydraulic System are: Boom Economy Control (BEC), which reduces RPMs by using gravity during boom down and swing; Auto Economy Control (AEC), which lowers RPMs during idle and automatically shuts down the engine after a preset idle time; Swing Relief Control (SWC), which reduces hydraulic power at the swing start; and Spool Stroke Control (SSC), which adjusts hydraulic pressure during digs. It actively manages hydraulic power throughout lift/dump and dig/curl movements to maximize speed and efficiency while reducing fuel consumption by minimizing unnecessary hydraulic flow. The operator experiences a more productive machine without losing the precision of the machine’s controls.

An Auto Power Boost feature provides increased breakout forces in tough applications, and overall operation is simplified with three Power Modes to maximize machine performance and fuel economy:

  • Automatic (A): The best balance between productivity and fuel efficiency
  • Heavy Duty (HD): High workload mode
  • Speed Priority (SP): Extra speed and power for the most demanding jobs that require maximum productivity

Greater Feature Standardization

CASE D Series excavators now offer more standard features than any previous CASE crawler excavator. This includes Free Swing for improved craning, laying or lifting of offset loads; oil sample ports for quick sampling of engine and hydraulic oils; and an easy pattern selector for the operator’s preference of ISO or SAE controls.

The CX145D SR features an industry-leading operator environment, with a more spacious cab, excellent visibility, a standard fully-adjustable heated air-ride seat, ergonomic multifunctional controls, and a pressurized, viscous-mounted cab that reduces noise and vibration. A standard Bluetooth radio gives operators hands-free functionality that further improves the operator experience. Standard rear-view and side-view cameras feed a 7-inch widescreen monitor that also provides operators with real-time access to important performance parameters, including fuel consumption, operating hours and machine information. The optional CASE Max View Monitor provides 270-degree visibility, improving jobsite safety and providing the operator full visibility of the machine’s surroundings.

 New Lighting Package

Each D Series machine is available with a new (optional) LED working light package that provides illumination than three-times brighter than halogen, allowing contractors to work around the clock. The LED package includes six LED lights (two front, two rear and one on each side).

 CASE ProCare

All CASE D Series excavators are covered under CASE ProCare – a suite of product assurances that includes a three-year Advanced CASE SiteWatch™ telematics subscription, a three-year/3,000-hour full-machine factory warranty, and a three-year/3,000-hour planned maintenance contract. ProCare allows business owners to invest in new equipment while helping to make owning and operating costs predictable for the first three years of lease or ownership.

Tom Ewing’s Environmental Update

*  If your friends tell you you’re full of wind, well, take it as a compliment and then tell them (assuming you have more than one friend *:D big grin) everything you’ve learned from reading DOE’s extensive and very user-friendly “2016 Wind Market Reports.”  Wow – great resource.  The reports update the continued growth in wind energy nationwide. The wind industry added more than 8,200 megawatts of capacity last year, representing 27 percent of all energy capacity additions in 2016. The reports cover the following market sectors:  land-based utility scaleoffshore, and  distributed wind.  Definitely worth a close read!
*  Well, it’s not quite at the out-sized status achieved by the Coast Guard’s 2016 proposal to establish safety/anchorage zones on the Hudson River.  You may recall that proposal generated over 10,000 comments from interested citizens, or at least citizens who knew how to flood the docket with form letters.  But the CG’s proposal for safety zones in the Puget Sound has turned into a similar hot button issue, indicating again how usually very low-key, ho-hum proposals can get morphed into flashpoints that, for some, indicate, well, just about the end of the world.  In its proposal the CG references its “preliminary determination that this action is one of a category of actions that do not individually or cumulatively have a significant effect on the human environment.”  Hah, nice try team!

*  Michigan’s DEQ has a series of videos documenting how that agency has helped redevelop some very challenging brownfield sites.  A new video was distributed last week about a project in Lansing, MI, on the Grand River, and it’s worth watching.  One comment, though: There were pictures of the old site, and old facilities, the polluting entities that left an abandoned disaster.  But something caught my eye, a bit unsettling.  The jobs at the new family-friendly site with fishing and boating excursions and sunny bike paths were mostly restaurant and retail, selling coffee and pizza and, likely, some very tasty local beers.  But, uh, hate to ask, where are the old-school jobs where people made stuff, created complex and complicated things using brains, raw materials and skill?  Yeah, decades ago they did it all wrong, environmentally.  But now we know better.  If those jobs and facilities wanted to return to the Lansing riverfront, could they?  Would they be welcome?  Couldn’t tell from the video…

Practice Smart Digging: AEM Supports “Call 811” Day

Practice Smart Digging: AEM Supports “Call 811” Day
8/11 on Calendar a Convenient Reminder from Common Ground Alliance

Do you know where your local utility lines are?

The Common Ground Alliance has designated 8/11 on the calendar as a convenient reminder to “call before you dig,” and the Association of Equipment Manufacturers (AEM) and its members are proud to support CGA and its programs.

“AEM and CGA have worked diligently together to promote safety in all utility excavation. Why? Because it saves lives,” said William “Bernie” Bernhard, AEM technical and safety services manager.

“Contractors, farmers, landscapers, homeowners and anyone involved in a digging project, no matter how large or small, needs to call 811. It’s a free call and the risk is just not worth it!”

Every six minutes an underground utility line is damaged because someone decided to dig without first calling 811, says CGA. From high-speed Internet, cable TV and phone to electric, gas, water and sewer lines, many are buried underground and hitting one can cause injury, repair costs, fines and inconvenient neighborhood outages.

Read Bernhard’s “8/11 Day” commemoration blog here, outlining CGA resources as well as AEM and machinery manufacturer “Call 811” outreach.

Visit the Common Ground Alliance website for more information on CGA and its services.

“Smart digging means calling 811 and using AEM’s safety manuals before each job,” says Bernhard.

AEM safety manuals specifically for underground excavation cover auger boring, backhoe loaders, compact excavators, digger derricks, directional drilling, hydraulic excavators, trenchers and vacuum excavators.

Visit safetymaterials.org as you prepare for your next excavation project.

AEM’s world-class trade shows include ICUEE, International Construction and Utility Equipment Exposition (aka The Demo Expo). Visit www.icuee.com for details on the 2017 show, set for October 3-5 in Louisville, Kentucky.

 

Products At Work: Hospital Built to Plan

MEP contractor’s technology precisely places plumbing / HVAC systems

By Jeff Winke

The Denver, Colorado suburb of Northglenn sold 5.7 acres of vacant land to SCL Health Community Hospitals for the construction of a 60,000-square-foot community-based hospital and medical office facility. The location is less than a half mile from I-25.

            The Northglenn SCL Health Community Hospital follows the new healthcare model, which favors smaller, more accessible hospitals located within neighborhoods. Yet, the three-story new hospital will provide many of the same services found in larger traditional hospitals, such as an emergency room, inpatient beds, and laboratory and imaging services.

            AMI Mechanical Inc., based in Thornton, Colorado, is responsible for the fabrication and installation of all the mechanical systems in this small building with its 218 foot by 88-foot structure footprint. All the systems were fabricated in house in a clean, controlled environment, which made for a cleaner, safer worksite. This was an approximate $5 million project.

            Since 1991, AMI Mechanical has established itself in the Rocky Mountain Region and handles projects ranging in size from $200,000 to $25 Million, with a yearly volume of $70 Million. In addition to their management, engineering and administrative staff, AMI Mechanical employs more than 275 skilled and experienced field trades workers. A crew of 20 or so worked on the SCL Hospital’s plumbing and waste piping system and eight to 10 were assigned to the project’s HVAC duct installation crew.

            “The structure is tilt-up construction so once the concrete side forms were tied in place and we received the green light to go, things moved fast,” states Sean Lauck, BIM manager for AMI Mechanical. “We had plenty to do on our end but we needed to coordinate with the various other contractors to make sure the interior construction went smoothly.”

            Hospitals require a lot of water, power, and proper air circulation for exam rooms and operating theaters, as well as X-ray facilities. It can be a more complicated build than a hotel or apartment building with similar number of rooms because of the critical need for environmental control and the sophisticated technology that can be used in the rooms.

            “We’re dealing with a four to 4½ foot ceiling cavity that can be packed with cables, piping, lighting fixture housing, air circulation systems, and structural I-beams, so we need to know where everything goes precisely,” Lauck said. “There was no room for missteps or errors.”

            Until the roof was built and enclosed the building, weather also became a challenge. There were bitter cold days and snowstorms. The snow and ice delayed AMI Mechanical until the decks were cleared.

            AMI Mechanical created a digital model, which represents the physical, technical, and functional characteristics of the Northglenn SCL Health Community Hospital building. The model included 3D coordinates and vector information that represent the geometry of the building and its components.

            The 3D digital model also details the entire network of piping and ductwork to be installed, as well as the structural elements, HVAC hanger anchor inserts, and penetration points on each deck where piping must travel through. 

           

LN_100_Application

“For each of the three decks, we’re placing 3,000 to 4,000 hangers alone, which translates to a large amount of data,” Lauck stated. “And each hanger needs to be anchored at its correct point, which is where our total station and layout navigator instruments play critical roles.”

            Lauck worked with GeoShack in Commerce City, Colorado to select the best technology for the project. GeoShack is an authorized Sokkia and Topcon dealer, which are products that Lauck has worked with for years, knows best, and prefers. GeoShack helped in selecting the best technology for the Northglenn SCL Health facility project and provided start-up assistance, training, and on-call troubleshooting help.

            Through GeoShack, AMI Mechanical acquired a Topcon PS-103 robotic total station, which is positioned as the most advanced robotic total station available. Because it’s designed to offer precision positioning capability, AMI Mechanical used the PS Series total station with  to ensure accurate placement of piping and ductwork hangers.

            Also acquired was a Topcon LN-100 Layout Navigator using MAGNET Layout software, which is considered the first 3D positioning system designed specifically for construction layout.  The LN-100 uses laser and robotic total station technologies to create a totally new tool. The challenge the LN-100 addresses is the construction coordination, which was essential for the Northglenn site.

           Lauck appreciated that the LN-100 could be mounted on a structural column so that there is less floor vibration than a floor tripod, which is susceptible to the jars and vibrations of materials being loaded on the floor for use,

            “Knowing what work has been completed during the project and working from the same design plan throughout is critical to maintain schedule and avoid costly collisions on this hospital project,” said Lauck. “The LN-100 helped us stay connected to the same design and focused on each critical step in the process.”

            Lauck also likes the fact that he can pair up the robotic total station and layout navigator with any brand of data collector. The Topcon instruments are not restricted to their own brand of data collectors, which provides the contractor with flexibility should there ever be a need and the only option is a competitive brand data collector.

            “Being able to access and apply the BIM 3D model through our robot and LN-100 made it possible to deliver the quality results we had planned,” Lauck stated. “Since we needed to coordinate our efforts with other contractors on the site, the technology allowed us to work faster and better—essentially accelerate our work flow when necessary to fit the needs of the other contractors.”
The Northglenn SCL Health Community Hospital facility was completed on schedule.

            “This will be fun to visit the Northglenn hospital sometime in the future just to see it fully functioning,” said Lauck. “I’ll feel good knowing we’ve done a good job and everything in the building’s mechanicals is in place… exactly where it needs to be.”

Dodge Momentum Index Stumbles in July

The Dodge Momentum Index fell in July, dropping 3.3% to 135.0 (2000=100) from its revised June reading of 139.6. The Momentum Index is a monthly measure of the first (or initial) report for  in planning, which have been shown to lead construction spending for nonresidential buildings by a full year. The move lower in July was due to a 6.6% decline in the institutional component of the Momentum Index, while the commercial component fell 1.1%. This month continues a recent trend of volatility in the Momentum Index where a string of gains is interrupted by a step backwards in planning intentions. Despite the decline from June to July, the Momentum Index is 6.9% higher than one year ago, which suggests further moderate gains in construction activity throughout the year. The commercial component of the Momentum Index is 8.0% higher than last year, while the Institutional component is 5.3% higher.

In July, nine projects entered planning each with a value of $100 million or more. For the institutional building sector, the leading projects were the $200 million Kaiser Permanente Medical Center in Woodbridge VA and the $200 million phase 2B of the Thompson Education Center in Rocky Hill NY. The leading commercial building projects were a $177 million Amazon fulfillment center in North Randall OH and the $170 million Pala Casino and Resort in Pala CA.
