The Los Angeles Department of Water & Power (LADWP) was established more than 100 years ago and is now the largest municipal water and power utility in the nation. LADWP delivers reliable, safe water and electricity to approximately 3.8 million residents and businesses in Los Angeles, with a water main leak rate that is half that of the national industry average. According to the LADWP website, leaks have decreased by 37 percent over the past seven years, due in part to LADWP’s proactive plan to


replace older and more vulnerable pipes. LADWP maintains 7,200 miles of pipe, including 6,700 miles of mains and 500 miles of trunk lines. Approximately 200 miles of pipe are more than 100 years old with another 637 miles reaching the century mark within the next decade, and 2,000 miles (27 percent) will surpass 100 years by 2030. It is clear that LA’s water infrastructure is getting older and LADWP recognizes the social and economic benefits of replacing this infrastructure before it fails. Under their current Water

Infrastructure Plan, LADWP will ramp up the replacement level to 57 miles each year, with priority given to 435 miles currently identified as having a high risk of failure. Trunk lines serve as the major arteries for water delivery and are typically 20 inches or more in diameter. Trunk line replacements are multiyear projects that cost tens of millions of dollars. LADWP’s focus is on testing and restoring weak sections of trunk lines first, rather than replacing an entire trunk line. The River Supply

Conduit Improvement Upper Reach (RSC) – Units 5 & 6 Project is located in the North Hollywood area of Los Angeles and consists of installing approximately 15,800 feet of 78-inch diameter welded steel pipe and appurtenances utilizing open trench, pipe jacking, and tunneling construction methods. W.A. Rasic/SAK Joint Venture is located in Long Beach and they are the general engineering contractor chosen by LADWP to complete this project. W.A. Rasic Construction will perform approximately 5,400 feet of open trench construction, mostly within Lankershim Boulevard (Victory Boulevard to Collins Street) and a short stretch along Burbank Boulevard (Strohm Avenue and Biloxi Avenue). SAK Construction will perform pipe jacking and tunneling on the remaining 10,300 feet within Morella Avenue, Archwood Street, and portions of Burbank Boulevard and Lankershim Boulevard, including Oxnard Street. Built in the 1940s, the River Supply Conduit (RSC) is a major pipeline responsible for transporting large amounts of water from the Northeast Valley area to the Central City area. In this particular case

approximately 90 percent (30,000 linear feet) of the RSC will be replaced. The RSC runs between the North Hollywood Pump Station and the Headworks Spreading Grounds site, located near Forest Lawn Drive just west of Victory Boulevard. The RSC Upper Reach will be constructed under two separate projects: RSC – Units 5 & 6 and RSC – Unit 7 and is expected to be completed in early 2018. W.A. Rasic/SAK Joint Venture’s received the notice to proceed Dec. 2, 2014, on the RSC 5 & 6 project, broke ground in March 2015, with a completion date of Oct. 26, 2017. The RSC – Unit 5 & 6 contract amount comes to $91,272,050. Money well spent when you consider that it will bring improved safety and system reliability, better water pressure, comply with all water quality regulations, offer increased water capacity and mitigate air entrainment. Jeremy Juarez is the senior project manager overseeing all aspects of this joint venture project. Jeremy has been with W.A. Rasic for nearly 10 years and joined the company after receiving his degree in mechanical

engineering and working for another pipeline contractor for a short time. “This project represents a couple of firsts for both the Joint Venture and W.A. Rasic Construction,” says Juarez. “W.A. Rasic has been proudly serving the underground utility construction industry since the 1970s and this Joint Venture project is our largest single project to date. We are also utilizing unique first-time construction tools and methods as well, including massive sound walls and a process known as permeation grouting to help protect existing utilities.” Juarez further explains that large-scale sound walls were constructed in Work Area 12 (Burbank Boulevard) as a noise abatement solution. “Work Area 12 represents the longest single run on this project and the city along with local residents and commercial businesses, including acting, recording and dance studios, were concerned about the possible negative effects the construction noise and activity could have on their daily lives and businesses,” says Juarez. “We constructed 24-foot high wood framed sound walls with

sound barriers on each side to absorb sound and help mitigate noise concerns.” Juarez goes on to explain that soldier beams were put in place to safely hold the sound walls in place. “Much of our equipment has also been modified with vibration muffling systems, as a requirement for working in certain sensitive areas on this project,” says Juarez. “These procedures seem to be a new focal point in our industry, as government agencies and municipalities continue to add them to their list of requirements.” Prior to tunneling in two specific locations, plans called for the installation of permeation grouting in order to firm up the poor cobble and sandy soil conditions. “It was necessary to tunnel 30 to 40 feet down in order to safely clear existing large diameter storm drains and sewer lines,” says Juarez. “Specifications called for a special technique known as permeation grouting in order to add structural integrity to the existing soil and to fill in any voids that may have been caused by any leakage that may have occurred over the years. We set up drilling locations around the utilities at various angles and depths and injected the grouting material through PVC conduit. This process successfully helped avoid heaving or loss of soil integrity while boring underneath the utilities.” Ryan Plunk is the project manager on the RSC – Units 5 & 6 project and he has been with W.A. Rasic for eight years, joining the company after working several years for Inland Empire building developers. Plunk points to another challenge that usually occurs on a job of this magnitude that travels through busy downtown streets. “With limited work space provided per plan, combined with the heavy traffic volumes we’ve encountered, it

is really critical that our work is phased accordingly in order to maximize production and efficiency, all while maintaining a safe work zone for our crews and the surrounding public. Each of our work zones are based on engineered LADOT traffic control plans that are approved prior to the start of the job,” says Plunk. “As a result, there is very limited parking and directing traffic around these busy LA streets is quite a challenge, however traffic is flowing pretty well all things considered.” Plunk says that the process is further complicated due to the use of the large, heavy machinery that is necessary to excavate for and install the large diameter pipe. “Logistics, weight, and work space are all a challenge and doing this while confined to an 11-foot lane wedged between the trench, traffic and the adjacent businesses and residences forces you to get creative at times.” Adding to the challenge of the congestion and close working quarters is the necessary use of very large construction machines. Equipment like W.A. Rasic’s Cat 385 excavators are used to assist in everything from soldier beam and sound wall installation to trench excavation and backfill, along with Cat 950 and 980 wheel loaders, and 10-wheelers and end dumps that travel in and out daily. These are all working above ground, but W.A. Rasic’s Joint Venture partner, SAK Construction, has something much larger lurking beneath the surface. “SAK Construction’s, Lovat mixed phase earth pressure balance machine (tunnel boring machine) has a cut diameter of 129 ½ inches and the overall length of the machine with all of the trailing gear is approximately 230 feet,” says Plunk. “A lot of work goes into getting this machine into place to do it’s job, including the excavation of nine

jacking and receiving pits, an immense amount of shoring, as well as sewer and other utility relocations.” The overall job also includes the erection of several structures, installation of geotechnical instruments, electrical and asphalt restoration, as well as traffic control installation and traffic signal modification. As a joint venture partner, W.A. Rasic is responsible for all of the shoring for the jacking and receiving pits, as well as all of the open-cut work. “LADOT heavily influences our work areas and some of the longer 800 to 1,500 linear feet cut runs require a little more planning. We have to stage our work accordingly,” says Plunk. We may have some excavation and pipe installation working during the day and then things like backfill and concrete pouring taking place on the swing shift when there is a bit more space to get trucks and machinery in and out.” W.A. Rasic also

serves as the managing partner on this joint venture, handling coordination and communication with the various agencies, including scheduling, change orders and any other contract or documentation work. Senior project manager, Jeremy Juarez is quick to point out that a job like this is only possible when you have the right people in place to assure that it all goes down safely and according to specifications. “Everyone at SAK and W.A. Rasic, from office staff and laborers to operators and management, has done a great job doing their part so that as a whole the project gets done according to plan. I am very proud of our entire joint venture team,” says Juarez. “I would like to recognize a few individuals like Jeff Ray, W.A. Rasic’s general superintendent for public works. Jeff has done a great job taking care of things like equipment purchases, shoring design and overseeing the field personnel.

W.A. Rasic would like to thank the SAK team led by owners Jerry Shaw, Robert Affholder, and Tom Kalishman for their involvement on a corporate level, as well as Sr. Project Manager James Byrd for his extensive knowledge in the tunneling industry. We would also like to thank SAK Project Superintendent, Frank Lynch, for his hard work in managing SAK’s responsibilities and SAK’s on-site manager, Brent Duncan for his tremendous contributions,” says Juarez. “I would also like to recognize Gilbert Estrada, our Project Superintendent, our two main engineers, Horacio Hernandez and Moses Vallejo, and of course our owners: Pete, Frank and Walter Rasic. Frank has been very involved from the beginning specifically where things like contracts, engineering, and field crews are concerned. It is great to have owners that embrace a hands-on approach to their business.”

With space at a premium, W.A. Rasic navigates excavation and installation of 78” Trunk Line through congested city streets and narrow work areas.

STEVE P. RADOS, INC. Works To Improve LADWP Water Distribution System On City Trunk Line South – Unit 4/Phase 2 Written By: Brian Hoover


he Los Angeles Department of Water and Power (LADWP) has played an integral part in the history of the City of Los Angeles since its inception in 1909. According to their website, LADWP hopes to invest $2.7 billion over the next five years to upgrade water system infrastructure reliability, spending all new water revenues on replacing and repairing critical pipes, pumps, valves and other waterworks in Los Angeles. In keeping with this plan, LADWP awarded Steve P. Rados, Inc.

(Rados) the City Trunk Line South - Unit 4/Phase 2 project March 4, 2015. With a contract value of $14,466,500, the project began in summer 2015 and is scheduled for completion in spring 2017. The City Trunk Line South Unit 4/Phase 2 project is located in San Fernando Valley in two isolated work areas, located approximately one-half mile from one another, near the on/off ramps of Coldwater Canyon and the 101 Ventura Freeway. The City Trunk Line was installed in 1914 and had been showing its age with a

history of leaks and breaks. The overall project entails installation of approximately 1,500 LF of 54” and 60” welded steel pipe, and appurtenances, including two 54” mechanical butterfly valves. Specific work site locations are on Magnolia Boulevard (between Leghorn Avenue and Goodland Avenue), and Whitsett Avenue (between La Maida Street and Kling Street). The jack and bore method is being utilized to install pipe in two tunnels while the Sequential Excavation Method (SEM) will be implemented in

the creation of a third tunnel. Additionally, the abutment walls of the Tujunga Wash Channel were widened and cored through to allow for the hanging of the welded steel pipeline beneath the bridge that crosses the channel. The new steel trunk line is being built to withstand the higher pressures expected to flow through the system in the future. Rados’ portion is 1,500 LF, with 445 LF being constructed through conventional open trench methods at depths of 12 to 14 feet. The remaining pipe will be hung, jacked or tunneled at depths between 25 to 55 feet. Rados subcontracted to Pipe Jacking Unlimited located in San Bernardino, to complete the pipe jacking work for this project. Rados excavated and shored a jacking pit on Magnolia Boulevard

that was 43 feet long, 16 feet wide and 38 feet deep. Pipe Jacking Unlimited utilized their closed face tunnel-boring machine to install a 69” ID steel pipe casing through which a 54” ID welded steel pipe was jacked into place and grouted. The 69” jack and bore on Magnolia Boulevard is located near Coldwater Canyon Avenue and it runs 148 feet. Rados has begun construction on a 2 phase bore pit on Whitsett Avenue. The initial phase calls for the bore pit to be shored and excavated approximately 20 feet wide, 40 feet long and 28 feet deep. Pipe Jacking Unlimited utilized this pit to tunnel and install 75” steel casing 360 linear feet to the receiving pit on Whitsett Avenue and to install and jack 60” steel pipe through the casing. After the pipe jacking operation is

complete, Rados will continue to excavate and shore the jacking pit an additional 27 feet to a final elevation of 55 feet below grade. The 55-foot deep pit will be utilized as a launch shaft for the upcoming 252’ upcoming section of SEM tunnel work. Derek Rados is the Southern California Heavy Division Manager for Steve P. Rados, Inc. and he is helping to oversee the day-today work on the City Trunk Line South – Unit 4/Phase 2 project. “Both jack and bores went smoothly although they were not without challenge,” says Rados. “Pipe Jacking Unlimited is a highly qualified outfit and we have a history of working together on many successful projects. Both pipe jacking projects were completed with no major issues due not only to Pipe

Jacking Unlimited’s expertise but also to LADWP engineers’ willingness to work closely with Rados management in order to quickly resolve any project issues or concerns. 252’ of trunk-line along Whitsett Avenue, from North of the Tujunga Wash Channel to the south of Riverside Drive, will be tunneled at a depth of 55 feet below grade. This tunnel was designed by LADWP to utilize the Sequential Excavation Method (SEM), also known as the New Austrian Tunneling Method (NATM). Put simply, this process mobilizes and maximizes the self-supporting capacity of the surrounding rock and soil, while being coated and sprayed with fiber reinforced flashcrete and shotcrete, along with other supporting elements. Construction is typically carried out in increments and in this case, 18 sections of pipe are being installed using the SEM method, including two elbows with a tunnel invert located around 48’ below existing grade. 60” inside diameter welded-steel carrier pipe will be installed in this tunnel section, and the annular space between the pipe and the tunnel liner will be grouted,” says Rados. “We are working together with Sylmar-based, FrontierKemper Constructors, Inc., our subcontractor on this portion of the project, who will perform tunnel excavation in 3-ft. long rounds using a compact excavator and hand mining excavation. A minimum of a 2-inch layer of flashcrete will be applied to the exposed earth, followed by a 5-inch minimum lining of shotcrete. Steel lattice girders will be placed every 3 feet, making this all a very expensive, time-consuming, and yet very safe installation process.” Rados continues by pointing out that the SEM tunnel work will mark the first of its kind on an LADWP project. “The massive concrete structure of the Tujunga Wash, including bridge piles extending approximately 70 feet deep from finish grade, make this a difficult substructure to install pipe around. The SEM tunnel is essentially designed to go under the channel of the Tujunga Wash and weave around the location of the bridge piles,” says Rados. Another unique and interesting section of this project is located at the Tujunga Wash Channel. It is at this location that 70 LF of 54” ID welded epoxy coated steel pipe was hung below the Magnolia Avenue Bridge that crosses the Tujunga Wash Channel. However, before any pipe could be hung, it was necessary to excavate 30’ deep pits and complete 62” cores through the Left: Pipe-Jacking Unlimited crew actively tunneling with closed face tunnel machine at Whitsett Ave jacking pit. Total tunnel length 360 feet.

existing abutment on both sides of the Tujunga Wash. “Carpenters installed forms so that we could pour concrete and increase the widths of the existing Tujunga Wash Channel walls to support the new load of the 54” pipe,” says Rados. “60-inch steel pipe sleeves were installed through the forms at the location of the cores before concrete was poured around the casing widening the Tujunga Wash channel abutments.” According to Rados, the pipe hanging operation required close coordination. “Three 54 inch steel pipes were taken into Tujunga Wash and stabbed and welded into place inside and out essentially creating one steel piece of pipe measuring 55 feet in length and weighing 21,000

pounds. A Kalmar 36,000 lb. single mast forklift was utilized to lift this pipe approximately 18 feet from the channel floor and to hold the pipe in place near the flowline,” says Rados. “Stainless steel pipe hangers were then installed through the bridge deck of Magnolia Boulevard crossing the Tujunga Wash. These were used to safely hold and support the 54” welded steel pipe in place while the forklift remained underneath it.” After this 50-foot section of pipe was secure, Rados pushed in an additional pipe joined from each side of the abutment through the 60” steel casing. This was done by using a John Deere 550 excavator from the surface and dropping the pipes into the shored pits on each side of the abutment and then

pushing the pipe joints through the casing over rollers to the location of the pipe stab in the channel. The men working on Magnolia Boulevard pushing the pipe with the excavator communicated closely with the workers inside the wash to align the pipe properly. The joints were then welded in place. A variety of heavy machinery and utility pieces are being utilized on this project, including a John Deere 550 excavator, a Cat 950 wheel loader, Cat 446 backhoe, Cat 247 skid steer, a Cat IT28 integrated tool carrier, as well as a Cat 330 excavator equipped with a LoDrill attachment for the drilling and installation of shoring soldier piles used to support a tremendous amount of steel beams and steel plates.

Kana Pipeline Performs Wet Utility Pipeline Installation Amidst Intense Groundwater Conditions Written By: Brian Hoover

The Cypress School District made the decision to close Dickerson Elementary School in Buena Park in 2009 in response to declining enrollment and the California recession. The site was declared surplus property in June 2013 and the school district finalized approval for an Exchange Agreement with real estate land developer William Lyon Homes, Inc. in September 2014. The land developer is now erecting 67 new single-family detached homes, including associated site, street, and recreation area improvements. The project was contracted as the Covey-BP-Dickerson, and is also referred to simply as, “The Covey.” The 9.6-acre property is located at the southwest corner of Ball Road and Bernadette Avenue in Buena Park. Construction began in November 2015 and is scheduled for completion in July 2017. Kana Pipeline, Inc. (Kana) was contracted to perform the wet utility pipeline installation, which was significant considering the degree of excessive groundwater conditions. The sewer pipeline construction includes the installation of

Kana also constructed and installed a 26’ deep storm drain pump station which presented its own challenge considering a relatively shallow 8’ groundwater table and this was almost 10’ deeper than their deepest utility install. “Timing is everything to stay ahead of the groundwater conditions and effectively install our pipeline,” added Sandoval. Once the curb and gutter and asphalt were poured on-site, they built catch basins and then installed Modular Wetlands™ units. Because they are required to retain as much water on-site as possible before releasing it to the city storm drains, Kana installed a retention basin with a pump station utilizing 60” RCP during the installation of the storm drain system. They also put in a 60” corrugated polypropylene pipe retention system utilized to hold as much water as possible. The water first passes through the Modular Wetlands™ filtering units, then into the retention system. When the retention system is

system also removes hydrocarbons and dissolved metals like copper, lead and zinc that come from products such as the brakes on our cars.” McKay further explains that a storms flush or rain water flow will pickup hazardous materials from our yards and parking lots to include everything from leaves, treated lawns and animal waste to roof runoff and a variety of other toxic materials like oil and metal. The Modular Wetlands™ system reduces the stormwater to a level that will not adversely affect the environment or waterways. It is a natural horizontal system utilizing an inorganic media that prevents leaching of phosphorus and dissolved metals and results in a reduction in pollutants being introduced into the storm drain. California Water Boards draw authority for stormwater regulation from the Federal Water Pollution Control Act (Clean Water Act), which establishes the framework for regulating stormwater discharges under the National Pollutant Discharge Elimination System (NPDES) Permit System. Cities and counties issue municipal MS4 (Separate Storm Sewer Systems) permits to operators that are required to develop a Below: Kana field crews installing corrugated double gasket drainage pipe at site of former groundwater lake bed.

stormwater management program. “Many cities and counties have MS4 regulations that are even more stringent than federal standards,” says McKay. “Orange County is one of those where regulations and tolerances are held to an even higher standard. When a job like this one in Buena Park has stormwater that may be discharged into tributaries like the Santa Ana River Basin and then make its way into the ocean at Newport Beach or Huntington Beach, Orange County wants to be sure that this water is clean and free of harmful pollutants.” The Modular Wetlands™ installed on the Covey project vary in size and are dependent on each location and individual treatment flows. “In this particular case, on the Covey project, we are treating from .144 CFS to .346 CFS per Modular Wetlands™ system,” says McKay. “We calculate many factors including the time of year, type of storm events and when peak flows occur for each individual city or agency. These calculations are also dependent on drainage area, tributaries, and many other factors.” The Covey project has seven Modular Wetlands™ systems installed ranging in size from 4’ x 13’ to 8 x 12’ and they all tie directly into existing catch basins.

IS IT ‘FISH OR CUT BAIT’ TIME FOR DELTA TWIN-TUNNEL PROJECT? California is proposing that we build two massive 40-foot tunnels under the SacramentoSan Joaquin River Delta in order to provide water to aqueducts that supply farms and cities in the south. According to reports, the tunnels would run 39-miles when you include the huge siphoning intake pipes. The delta is located roughly between Sacramento in the north and Stockton in the south and encompasses around 1,000 miles of waterways. The main rivers contributing to the Delta are the Sacramento River and San Joaquin River with the American River, Mokelumne River, Cosumnes River and the XCalaveras River feeding into these two main rivers. The delta is California’s main local source of water, irrigating some 3 million acres and supplying drinking water to an estimated 24 million residents. The current pipeline is in disrepair; and many agree that maintenance or some sort of new construction is needed. The $16 billion question is, “do we need two massive tunnels” that opponents say will actually be more like $50 billion when you consider everything including construction, financing, operation and environmental mitigation. Proponents of the Delta tunnel project say, “yes.” One argument is that current pumping methods have altered the natural flow of the waterway, pulling migrating native fish off course, and adversely affecting plants and animal species in the process. According to reports, a minimum of 35 native fish, plants and animal species are now listed under federal and state endangered-species acts.


Those promoting the project say that a new diversion system and habitat restoration could restore proper flow to the Delta, with hopes of reversing the plummet in species like delta smelt and salmon. They argue that the tunnels would provide a more efficient water source to the south and that the cost would be the burden of the cities and farmers residing primarily in the driest areas of California, including the San Joaquin Valley and the City of Los Angeles. California has already won one hearing delay and is currently seeking a second. Their dream seems to be for an ecologically better and more reliable water source. Opponents include residents and farmers who live near and benefit from the Delta. They fear that the state would take too much water from the already failing ecosystem and in the process devastate their way of life. They also point to the effect that 10 to 25 years of construction would have on their communities

with trucks moving more than 30-million cubic yards of earth. Additionally, an earlier $7 billion conservation plan aimed at preserving fish, plant and animal species has been changed and reportedly all that is left is $300 million toward a habitat restoration project. Decision time is coming soon and it appears that getting the proper approvals and permits will continue to face fierce opposition. Proponents of a better water supply system for California continue to look for answers to future droughts and continued demand for fresh water in the south. One thing is for sure; Governor Brown has no shortage of big ideas. Perhaps building a high-speed rail system within the 40-foot tunnels would help facilitate the permit process. All jokes aside, is it time to fish or cut bait on this issue? Only time will tell if California will get some sort of solution and relief toward the water supply/shortage dilemma. Cc

NEW JOHN DEERE 700K SMARTGRADE™ DOZER OFFERS CONTRACTORS A COMPETITIVE EDGE The John Deere 700K SmartGrade™ crawler dozer is improving jobsite accuracy and quality of work through its complete integration of the Topcon 3D-MC2 Grade Control System. The system is fully integrated into the machine cabin, structures, and software – delivering precise grading performance while eliminating vulnerable external masts and cables. The SmartGrade technology enables operators to be more productive on the jobsite. Because SmartGrade is integrated into the 130 hp 700K, it removes the need to install equipment daily, reducing setup time. Eliminating external cables to the masts reduces breakage, and the

removal of the masts from the blade eliminates vulnerability to damage and theft. The Auto SmartGrade feature allows the operator to easily adjust the system when moving the machine from one soil type to another, unlike an after-market system, which often requires the GPS manager to make a trip to the machine to recalibrate the system. Especially helpful to new operators, Auto SmartGrade

automatically lifts the blade over heavy loads before track slippage occurs, then returns the blade to grade. SmartGrade also limits the number of passes required, reducing the pace of wear on the undercarriage. Machine dimensions are preloaded into the grade control monitor, reducing the time required to calibrate the dozer to about 30 minutes. Additionally, the easy-to-use system is beneficial to new operators in that it can get them up and running quickly. SmartGrade dozer can pay back its purchase price in one to two jobs. Cc

NEW DESIGN FOR CAT® 630K SERIES WHEEL TRACTOR-SCRAPERS INCLUDES TECHNOLOGY THAT ADDS PRODUCTIVITY AND OPERATOR CONVENIENCE The new Cat® 630K Series wheel tractor-scrapers—631K and 637K—replace the previous 630G Series and feature a complete design update, including high-pressure steering, engine-over-speed protection, tire-spin reduction, differentiallock-engagement protection, and machine/ground-speed control, plus available systems such as Sequence Assist, Load Assist, Payload Estimator, and Cat Grade Control. Payload capacity of the open-bowl 631K and open-bowl twin-engine 637K is 34 cubic yards and 50 cubic yards for the coal-bowl 637K. Redesign of 630K Series models also includes a number of features developed for other Cat K Series models: the Advanced


Cushion Hitch uses new software to dampen end-of-stoke movement of the load cylinder for a smoother ride; hydraulicsystem refinement simplifies the bowl quick-drop function; and draft-arm-overflow guards divert material away from the sides of the bowl. In addition, a new Auto-Stall system assists in quickly bringing the transmission to operating temperature for faster transitions from torque-convertor drive. New

cab interiors feature a redesigned dash, as well as visibility and operator-comfort enhancements. Maintenance improvements include a ground-level-service filter bank, and the 637K’s Fuel Economy Mode adjusts shift points and power distribution for optimum fuel economy. Engine over-speed protection automatically senses engineover-speed conditions, based on the rate of acceleration, and applies the compression brake or service brakes with no operator input. Cat Grade Control, when selected, “intelligently” controls the loading cycle to ensure that the machine does not cut below grade avoiding excess material movement and rework. Cc

TEN TIPS FOR BUYING A NEW EXCAVATOR FROM YOUR CASE DEALER When it comes to purchasing a new excavator, there are many important items to consider. Understanding the right specs and knowing what to look for will have the greatest impact on the productivity of your business. Here is a list of ten important considerations for buying a new excavator. 1. Operating weight/size, Application It’s important to match the right size machine to the tasks at hand. Crawler excavators are generally grouped into three sizeclasses; compact/mini (0 – 6 metric tons; or <13,227 pounds), mid-size (6 – 10 metric tons; or 13,227 – 22,046 pounds) and standard/full-size (10 – 90 metric tons; or 22,046 – 198,416 lbs). 2. Hydraulics Consider the attachments you plan on working with, and understand the hydraulic flows required for each. Equipping your excavator with the right attachments will give you versatility to get the most out of your investment. Also, be sure to ask about the machine’s coupler options. This will often help determine the scope and variety of attachments you can use with the machine. 3. Transportation/Access When purchasing a new machine, transportation is always an important consideration. Depending on your current fleet, a larger trailer may be needed to haul your new excavator. You may also need to consider traveling on weight-limited roads bridges, as well as the necessary certification for your drivers. 4. Controls Consider the needs of the operator when purchasing a new


excavator. Most operators have a strong preference between ISO or SAE control patterns. To make things easier, many new excavator models—including the CASE D Series—offer an easy pattern control selector that allows the operator to adjust the machine to their preference. 5. Operator Comfort and Ergonomics When you’re in the cab of an excavator for ten hours a day, comfort and ergonomics are critical for productivity. Look for features in the cab that will keep your operators comfortable and focused on the job. 6. Tracks and undercarriage It’s important to understand the many track options available to you, as well as the impact that they can have on the productivity of the machine. Most compact excavators will come standard with rubber tracks, which are designed to minimize surface damage during travel and operation in the residential, street and in-building applications that they are often used. Rubber tracks wear out more quickly than steel, so there are a large variety of aftermarket track types available with varying widths and tread depth. 7. Tier 4 solutions Today’s Tier 4 Final excavators are equipped with a variety of engine types and after-treatment technologies, and knowing the

2016 underground construction ISSUE CALCONTRACTOR

differences, as well as the impact that they can have on your operation, is essential when making a purchasing decision. 8. Additional features Today’s excavators are loaded with additional features, so make sure that you are aware of what’s available to you when you decide to make a purchase. Features like selectable power modes and autoidle can have a real impact on fuel savings and overall operating costs. 9. Choosing the right dealer Choosing a dealer should be a long-term commitment. Your dealer is who you will rely upon throughout the lifetime of your equipment when you need parts, service and repairs. Look for a knowledgeable dealer with a robust service department, who has partnered with manufacturers that have reliable parts distribution networks. The best manufacturers provide regular training for their dealer technicians and sales staff, and have training resources available at all times. 10. M  aintenance contracts/ Warranties When you’re ready to purchase your new excavator, be sure to talk to your dealer about machine warranties and available extended maintenance contracts. When it comes to purchasing new equipment, protecting your investment is one of the most important considerations. Most manufacturers offer standard warranties on their equipment, but a premium service/maintenance program will make a significant impact on your overall cost of ownership. Cc
