Tunneling into the New YearAs we enter 2007, the future of the North American

tunneling market looks bright. There is huge demand fortunnels on both coasts, as well as work for sewer tunnelsin the middle of the country.

Major upcoming or ongoing projects in New York aloneinclude the Second Avenue Subway, East Side Access, No.7 line extension, a new trans-Hudson tunnel and continuedwater system improvements. In Southern California, workis ongoing on the L.A. Metro Gold Line East SideExtension with talk of further subway expansion towardSanta Monica in addition to various water tunnels. In SanFrancisco there is ongoing work related to the subway,plus talk of a high-speed rail line, which would include 30-plus miles of tunnels, extending from San Francisco to San Diego.

Major sewer overflow relief projects are ongoing or upcoming across thecountry, including Boston, Washington, D.C., Cleveland, Detroit, St. Louis,Indianapolis, Portland. Seattle remains a hotbed of activity with design workongoing for the Alaskan Way viaduct replacement project, Sound Transit subway work and Brightwater treatment plant and related tunnels.

In all, some $30-plus billion in tunnel work is projected annually to maintaincurrent levels of service and meet future demand. Not surprisingly, we are seeing changes in the industry. More foreign contractors are entering the market, and new contracting methods – including design-build, alliancing, risksharing, public-private partnerships – are being explored.

While it is an exciting time, there are questions concerning the pool of skilledpeople available to complete the work, the ever-present funding issues, andmore stringent requirements on safety and security standards.

Upcoming EventsThe major trade show for North America in 2007 is the Rapid Excavation

and Tunneling Conference (RETC), which is scheduled for June 10-13 inToronto. RETC has been growing over the last few years and with the level ofactivity this promises to be another can’t-miss event. [Just a reminder that U.S.citizens will now need a passport for travel into and out of Canada.]

Other tunneling events on the calendar include the annual George A. FoxConference (www.smenet.org), scheduled for Jan. 30 in New York City, and theUTRC general meeting (www.utrc.org), which is scheduled for March 23-25 in Seattle.

Here’s looking forward to a successful 2007.

Nancy Creek Tunnel Project Wins “Best of 2006” Award

Southeast Construction, a McGraw-Hill Construction regional publication,named the Nancy Creek Tunnel andInfluent Pumping Station in Atlanta awinner in its “Best of 2006” awards, anannual competition that recognizesprojects throughout Georgia, Florida,North Carolina and South Carolinathat demonstrate engineering excel-lence in design and construction. Some78 award recipients were honored at aBest of 2006 awards luncheon, heldNov. 28, 2006, at the Omni Resort atChampions Gate in Orlando, Fla.

Jordan, Jones & Goulding (JJG), anAtlanta-based consulting engineeringfirm, served as design engineer andconstruction manager of the tunnel for

the City of Atlanta’s Department of Watershed Management.The accelerated design and construction of the $131.5 million,8.3-mile long, 18-ft diameter deep-rock tunnel and its $32 million, 100 million gallons per day pumping station were completed under budget and in compliance with a specifiedcompletion milestone.

This year’s Best of 2006 award recipients were selected fromsome 138 projects. An independent panel of industry expertsand professionals selected this year’s winning projects based onsolutions to construction or design challenges, project manage-ment, construction or design innovation, client service and safety. Design entries were judged on unity with nearby societaland environmental elements, along with other criteria.

The Nancy Creek Tunnel project has been recognized withvarious prestigious industry awards, most recently including a2006 Outstanding Civil Engineering Achievement Award (LargeProject Category) presented by the Georgia Section of theAmerican Society of Civil Engineers. With its innovative design,the tunnel has quickly become a prototype in the region, servingas the epitome of excellence in engineering.

People


Dr. Mole has decided to throw in thetowel! It may be hard to believe forthose of you who have worked with meover the years, but it seems that I havesimply run out of things to say. It is alsohard to believe that I have been writingthis column for almost seven years;during which time my level of respectfor newspaper columnists who mustwrite something meaningful on a dailyor weekly basis has risen considerably.

The first Dr. Mole in April 2000 stated that the primary thrust of thecolumn would be to discuss risk management for tunneling projects.Over the years we have discussed ownerand contractor responsibilities, bettercontracting practices, contractor pre-qualification, alliancing, value engineer-ing, dispute resolution and many othertopics. In addition, we have had thebenefit of many guest columns — espe-cially those written by Sweet Old BobPond. Bob’s discussions of tunnelingfrom the contractor’s perspective wereextremely well written and informativeand Dr. Mole thanks him heartily forhis input. Dr. Mole would also like tothank many other members of our tun-neling fraternity for either writingcolumns or for providing me withinput/suggestions about various topics.

Each year Dr. Mole has been most interested in the RoundtableDiscussion provided by TunnelBusiness Magazine and this year’sroundtable was particularly informa-tive. Bob Smith, Dave Corkum, BobFitzgerald and Randy Hafer discussedseveral topics relating to risk manage-ment. David Hatem’s commentaryabout this year’s roundtable, whichwas published in the October issue ofTBM, was also pertinent. In general,these five gentlemen placed primaryresponsibility for the satisfactory out-come of a tunneling project on theshoulders of the Owner and theOwner’s Design consultants and Dr.Mole agrees with that emphasis. As Dr.Mole has said many times in this col-umn, the Owner sets the stage for

everything that follows, and in addi-tion, only the Owner is around to bene-fit from the long-term value of thecompleted project.

To summarize seven year’s worth ofcolumns, Dr. Mole would like to reiterate six items that he believes arecrucial to success in tunneling.

1. The Contract Document — TheOwner must prepare a contractdocument that is specifically tai-lored to tunneling and whichdescribes as precisely as possiblewhat must be accomplished inorder to produce a satisfactoryfinished facility. In addition, theContract must provide as muchflexibility as possible with therespect to the temporary facilitiesand the construction means andmethods in order to take advan-tage of the Contractor’s innova-tion and efficiency.

2. Geotechnical Information — Thesingle most important part of thetunneling contract is the geotech-nical information — usually dataand interpretive reports — andthe single most important empha-sis of those reports should be totell the Contractor what he mustaccomplish in order to build theproject. Geotechnical reports thatare written primarily as CYA doc-uments for the Designer and theOwner are counterproductive withrespect to a satisfactory projectoutcome.

3. Third-Party, Environmental andCommunity Promises — All mod-ern contracts, whether above orbelow ground, are littered withspecial requirements for thirdparties and environmental andcommunity considerations. Ingeneral, the scope of theserequirements seems to be expand-ing exponentially with significantcost and scheduling implications.

(Dr. Mole remembers one projectwhere all work had to stop for sixweeks because of a golf tourna-ment!) The Owners are free tomake as many of these promisesas they like, but they must beready to accept the cost conse-quences of those promises.

4. Contractor (Pre)Qualification —There are very few Contractors inthe United States that specializein tunneling, and it is highlyadvantageous to have one of thosecontractors working on your pro-ject. Tunneling is not conducive toon-the-job-training! It is rare forunqualified contractors to bidand/or to win a tunneling project,but when it happens, the outcomecan be exceptionally unpleasant.

5. Dispute Review Boards — DRBsare especially useful for smooth-ing out the wrinkles in a well prepared and well implementedcontract package. But, as SOB hassaid, when problems arrive by theboxcar, then the DRB is littlemore than a way station towardlitigation.

6. Code of Practice — Owner’s mustmake an effort to educate them-selves about good contractingpractices for tunneling projects orthe insurance industry will do itfor them. In general, Dr. Mole is abeliever in self-discipline.

In closing, I would like to thankTBM for the opportunity to be Dr.Mole and to provide commentary abouttunnel design and construction. I hopethat you have enjoyed reading thesecolumns as much as I have enjoyedwriting them, and good luck with yourfuture tunneling endeavors.

A 10-m (32.8-ft) diameter single shield TBM began boring onthe Lot 4 west tunnel of the Pajares tunnel project in August2006. The machine was designed by Robbins and built by MHI-Duro Felguera in Spain. Robbins is supplying the backup sys-tem, electrical and hydraulic components, field service, shieldengineering and part of the conveyor system. The project is part

of Spain’s Alta Velocidad Española (AVE) high-speed rail linkand includes two parallel 10.5-km (6.5-mile) long tunnels fortraveling both east and west.

The AVE is a high-speed rail system that will link Madrid andBarcelona to almost all other provincial cities by 2010. Oncecomplete, travel times will be cut to under 6 hours for Barcelonaand to under 4 hours to Madrid. A network of high-speed trainswill transport passengers at top speeds of 350 km/h (217 mph)over a system of more than 7,000 km (4,349 mi) of track.

Robbins designed the single shield TBM with several uniquefeatures to combat difficult ground conditions. An articulatingcutterhead can overbore 400 mm (15.7 in.), allowing the machineto continue boring in highly pressured rock. The cutterhead isalso a mixed face cutterhead for boring in blocky ground.

A continuous lining of 500 mm (19.7 in.) thick precast concretesegments is being erected to line the tunnel as the TBM bores. Aunique conveyor system, provided by Robbins, is integrateddirectly to the backup system and reduces the number of transferpoints between conveyors. The conveyor design saves space in thetunnel since only a short transfer conveyor is needed to join thebackup conveyor to the main tunnel conveyor. Additionally, themaintenance time on the conveyors and the potential for break-downs is significantly reduced compared to traditional conveyorsystems, which would typically use a system of three conveyorsthrough the backup to transport muck to the tunnel conveyor.

Connecting the Past & PresentTunneling in an urban area is tricky business; existing

structures, buried utilities and surface transportation are just afew of the problems faced when building underground facilities inthe heart of a city.

And this isn’t a new phenomenon. William Barclay Parsons,chief engineer for New York City's first subway line, needed tocarefully consider myriad aspects as the work progressed.Parson’s cut-and-cover design had to take into account:

“What precautions are necessary to ensure the safety ofthe valuable buildings near to the excavations; ...how todrive tunnels, divert sewers over or under the railways,keep up the numerous gas and water mains, and maintain the road traffic when the railway is being carriedunderneath; and finally, how to construct the covered way sothat buildings of any height and weight may be erected overthe railway without risk of subsequent injury from settlement or vibration.”Coincidently, the company that Parsons founded more than

120 years ago is facing many of these same challenges today as itis involved in projects that constitute the first large-scale NewYork subway system expansion in the last half-century. Foundedin 1885 by William Barclay Parsons, Parsons Brinckerhoff Inc.(PB) has grown to become a worldwide consulting firm withapproximately 10,000 employees providing infrastructure services in six continents. The employee-owned company operates in three divisions under the Parsons Brinckerhoff Inc.umbrella: PB Americas, PB International and PB Facilities.

While the firm operates internationally on projects includingtransportation, power, buildings and telecommunication, PB’s

roots are in the tunneling market. In fact, Parsons originallyfounded the company with the intent of engineering the NewYork subway, the most heavily traveled system in the UnitedStates and one of the world's busiest.

Today, PB’s tunneling resume includes many landmark pro-jects, from subway work in New York, Los Angeles, Washington,D.C., San Francisco and Atlanta, to highway projects includingSeattle’s planned Alaska Way tunnel and the H3 Tunnels inHawaii. The group is also involved in large-scale water andwastewater projects from coast-to-coast.

“We got our start in the tunneling field — the New York Citysubway was our very first project — and tunneling work has beenat the core of the business ever since,” said Tom O'Neill,Chairman and CEO of Parsons Brinckerhoff Inc. “It's one of thespecialties that we have that sets us apart from our competitors.”

HistoryWilliam Barclay Parsons set up shop as a consulting engineer

in 1885 — principally with the idea of building the New York sub-way, the idea of which was gaining momentum at the time. Whileconstruction of the subway had to wait 15 years before the political atmosphere was right, Parsons embarked on a series ofprojects ranging from railways and bridges to water systems andhydroplanes. One of the most notable projects was surveying theroute for the construction of a 1,000-mile railway from Hankowto Canton in China.

In 1906, Henry Brinckerhoff was brought on board.Brinckerhoff was known for his co-invention of the third rail, amethod of powering urban railways that eliminated the problems


associated with steam powered trains in confined spaces. Throughthe years the firm would add other prominent engineers —Eugene Klapp, Soren Thoreson, Walter Douglas, EugeneMacdonald, Maurice Quade, John Bickel and Tom Kuesel.

Despite Parsons’ death in 1932, the firm continued to grow —as did the list of successful projects. Notable underground pro-jects included the Detroit-Windsor Tunnel (the first subaqueoustunnel connecting two countries), the Fort McHenry Tunnel,and the NORAD and Fort Ritchie underground hardeneddefense facilities, in addition to rapid transit systems in LosAngeles, San Francisco and Atlanta. And while PB is noted forits transportation expertise, the company has a growing list ofprojects in water/wastewater conveyance including outfall tun-nels in San Diego and Boston, the Singapore Deep TunnelSewer System, and Portland's Willamette River Westside andEastside CSO tunnels.

But while the firm has a rich history in the underground business, PB leaders today are not living in the past. In fact, theyare eager to further the pioneering spirit of the company founder.

“We are dedicated to upholding the legacy of William BarclayParsons, the founder of our firm, who has been considered bymany historians as a pioneer, an innovator and a true renaissanceman in the field of tunneling and underground engineering,” saidGeorge Munfakh, PB senior vice president and manager of thefirm’s Geotechnical and Tunneling Group. “To live that legacy, itis our policy to give our people the support, encouragement andfreedom to use their skills and imagination to conceive new ideas,and to have the courage to innovate. This policy has worked well,and has led to the development of many innovative designs andcutting-edge applications on our projects, and placed our firmand people in the forefront of our profession.”

InnovationAs the demand for water, wastewater and transit projects rises

— while at the same time available funding is harder to come by— there is an increasing need for innovative design and construction methods to minimize building costs and keep thetunnel alternative competitive.

“At PB we've been designing tunnels for more than 100 years— but we're not doing it the same way,” Munfakh said. “We mustcontinue to develop state-of-the-art designs that narrow the gapbetween tunnel construction and surface construction costs. Wehave seen improved mechanization and other innovations thatallow tunnel projects to be completed more quickly and econom-ically than they have in the past, making them more attractive to clients.”

But innovations don’t happen by accident, so PB has established a framework to cultivate innovative thinking. One ofthe most recent additions to the PB tunneling team is the TunnelConstruction Engineering Unit. Headed by Tom Peyton, an engi-neer whose background is from the contractor’s side of the busi-ness, the group is focused on delivering designs with an empha-sis on constructability.

“We saw that designs were becoming too prescriptive, and itwas our view that it would be more beneficial to produce a buildable design that allows contractors the flexibility to work totheir strengths,” Peyton said. “This kind of approach encouragesinnovation and can help lower the cost for the owner. As long asthe end-product is safe and reliable, it's OK to find a cheaper wayto build the structure.”

This contractor-centric approach involves developing cost esti-mates not based upon unit prices, but on figuring crews, equip-

with State-of-the-Art Solutions

ment and materials. It also requires instilling a new approach todesigners who may not have a background in contracting.

“The most important thing to me is to communicate to thedesigners early on that the decisions they're making have amajor impact on the final success of the project,” Peyton said.“They need to think about how the project will actually be builtas opposed to just thinking about the design ... and that takes adifferent mindset.

“For instance, in the case where a tunnel may increase in size,there is a tendency for a designer to want to gradually flair it outto reduce the amount of excavation and the amount of materialsneeded for support. But from a construction standpoint, it’s eas-ier if the tunnel is stepped out. That way you don't have to changeyour forms every day and it allows you to get into a cycle.

“Once the designers start thinking about making the tunneleasier to build, that's when you can start realizing cost savings forthe owner.”

In addition to assisting with designs, the Tunnel ConstructionEngineering Unit conducts risk analysis and management, con-structability review, estimating and scheduling, construction doc-uments and contracting services.

Another new area for PB is the firm's Geospatial Servicesgroup, which uses advanced computer technology to assist inmanagement of complex subsurface data, and visualization anddesign of underground projects. Services include GeoDataManagement System and 3D subsurface modeling to visualizesubsurface stratigraphy, geological features, shear zones, liquefi-able soils, existing underground structures, groundwater regionsand contaminated plumes.

PB uses Virtual Design & Construction (VDC) techniques toimprove project delivery and stakeholder communication formajor underground projects by first planning, designing, con-structing and operating projects in a virtual computer model. Inthe PB CAVE — or Computer-Aided Visualization Environment— clients see a project rendering as it will be built to help in theplanning process, as well as serving as a communications tool for stakeholders.

“Instead of volumes of paper records of all varieties of subsur-face data, a Web-based geodata management system, combinedwith virtual design and construction techniques, will be thefuture platform that bring designers, contractors, and ownerstogether on major tunnel and underground structure pro-jects,”said Jeremy Hung, operations manager of theGeotechnical & Tunneling group.

Through its in-house research fellowship program, PB hasdeveloped new technology regarding seismic designs and designs

that take into account explosions within tunnels. “Following 9/11many of our clients were concerned about blasts in their struc-tures, so we evaluated technology and information from otherapplications, like above-ground buildings, and developed newanalytical procedures for implementation into our tunneldesigns,” said Nasri Munfah, PB vice president and NationalTunneling Practice Leader. “Through this research we are ableto improve the structural durability of the tunnel liner.”

Munfah also looks to other places — like Europe and Asia — fornew ideas. "There are technologies that are emerging overseasthat can be implemented elsewhere,” Munfah said. “We recentlyutilized the Double-O-Tube, a two-headed TBM in Shanghai fora subway extension project which was the first use of that technology outside of Japan.”

ClientsWhile technology plays an important role for any consulting

firm, PB recognizes that ultimately it is just another tool for help-ing the client. “Our focus is not to promote a specific technologyor approach — our goal is to help our client,” Munfah said. “Andthe best way to help, is by asking questions and listening to theclients before we embark on our design.”

Said Jim Monsees, PB senior vice president and technicaldirector: “We know our clients by name and pick up the phoneand talk to them about potential or ongoing projects. We also

work very closely with the clients to make sure they are gettingthe best design for their need.”

In the New York metropolitan area, PB is active in severaltransit projects, including the No. 7 line extension, East SideAccess, Trans Hudson Express (THE) Tunnel (formerly knownas the Access to the Region's Core), and the Fulton Street TransitCenter — three of which fall under the umbrella of theMetropolitan Transit Authority (MTA).

“With the complexity of these projects we need consultantswith technical expertise in many areas," said Mysore Nagaraja,president of MTA Capital Construction, which oversees systemexpansion projects for MTA. "We need geotechnical expertise,systems expertise and tunneling expertise, as well as the archi-tectural capabilities for stations, and PB has provided therequired expertise.”

PB has also been working with the Los Angeles MetropolitanTransportation Authority on the construction of its subway sys-tem dating back to the early 1980s. Dennis Mori, executive offi-cer of project management for MTA, said that experience wasalso a key factor in selecting a designer.

“We were looking for firms that have experience in tunneldesign and transit system design — specifically undergroundtransit,” Mori said. “PB has the depth of experience that we werelooking for and they have recognized experts in the field.”

LA MTA’s most recent project is an extension of the MetroGold Line, which involves six miles of light rail with 1.7 miles ofPB-designed tunnel. Tunneling began in February 2006 and thefirst of two tubes holed through in November.

“This is the first time that we've used EPB machines for sub-way tunnels and we also used one-pass, precast, bolted and double-gasketed concrete segments,” Mori said. “This systemreduced the overall time of tunneling and we were able to

complete the drives with no measurable surface settlement.”The success of the project could lead to more subway work in

the area. “There was concern about tunneling in the L.A. area,but this project has given politicians confidence in extending theMetro Red line west toward Santa Monica,” Mori said.

FutureWhile the future of the tunneling industry in North America

looks bright for the foreseeable future, PB is continuing torefine its toolbox to meet the challenges of the new wave ofprojects. Whether it is refining contracting methods orresearching new technologies, PB is well positioned to main-tain its role as a full-service provider for complex under-ground infrastructure projects.

“Unlike some firms that may have specialists in certain areas,we have a full complement of services that we can provide for theclient,” Munfakh said. “Whether it's water, utilities, trains orcars, we provide the whole service including the transportationelements, lighting, ventilation and communication.”

The company's toolbox, experience and commitment to clientshave allowed it to operate for more than a century, and companyofficials are looking forward to many more years of service.

“We take a long-term view,” O'Neill said. “We've been in busi-ness over 120 years and we want to stay in business for overanother 120 years and more — and the only way we can do that isto stand by our clients through thick and thin. We don’t just comein when there's a hot project to do; we want to establish ourselvesin a geographical area and establish a relationship with a clientfor the long haul.”

Situated near the shores of the Chesapeake Bay, Baltimore isa major port city and the cultural and commercial center ofMaryland. Referred to by some as the country’s northernmostSouthern city, and others as its southernmost Northern city,Baltimore has an identity all its own that is reflected by anothernickname, “Charm City.”

And while Baltimore is unique in many ways, it shares thesame problems confronted by many cities of its size – agingsewer and water systems that are in need of repairs andupgrades. Faced with a consent decree to address sanitary andcombined sewer overflows, the city has been actively engaged ina series of sewer system improvement projects to reduce thenumber of overflows and address capacity issues for futureneeds.

One of the most recent projects is the Lower Gwynns RunInterceptor, which was designed as a 13,000-ft stretch of 30-in.pipe through residential and commercial areas in the city’s west-ern side. Plans called for most of the pipeline to be installed bymicrotunneling through moderately hard to soft rock and mixedface conditions.

Carp-Seca Corp. was awarded the project and began work inMay 2006. However, once work got under way, crews found theBaltimore terrain anything but charming.

“The main challenges were in the variation of the rock massquality,” said Paul Headland, an engineer/geologist with Black &Veatch. Headland was involved on the design of the project withhis former employer, URS Corp. “Along the alignment there waspiedmont, metamorphic rock – gneiss, schist, amphibolite and

quartzite – all highly variable both in terms of the rock profileand the rock properties themselves.”

In some cases, the rock was harder than anticipated, so hardin fact that it stopped the microtunneling crew in its tracks.

“There were sections of rock that were in excess of 37,000psi,” said Steve Leius of Carp-Seca Corp. “We tried changingcutters and cutterheads, but there were certain areas where wewere not able to achieve penetration.”

Finding an Alternate SolutionWhile crews were able to microtunnel a good portion of theplanned alignment, they had to find other means for the areaswith hard rock. One of the tools that they turned to was expan-sive mortar, a product whose roots can be traced back 150 years,according to Mike Daigh, founder of Daigh Co., the distributorfor the Da-mite brand of rock-splitting mortar.

Daigh said that expanding mortar was used in Italy more thana century ago for splitting blocks of rock in quarry applications.He added that it gained prominence in the civil constructionindustry in the 1970s in Japan. “In Japan, there were concernsabout blasting for rock excavation because of the urban densityas well as liquefied soils.”

The technology has been in use in civil projects in the UnitedStates, including Yucca Mountain, the Carnegie Hall expansionand East Side Access projects in New York, and a jacked boxtunnel in frozen ground in Boston. Daigh says that the productis ideal in situations where blasting is restricted or where thereare seismic or vibration concerns.

He added that recent improvements in the technology haveallowed the mortar to be used in larger drill holes, making itmore effective and economical.

In Baltimore, Carp-Seca crews used it along areas of the LowerGwynns Run Interceptor alignment that were changed to opencut, as well as some areas that were planned for microtunneling.

“I had used the Da-mite productbefore on other projects in the past andit was very effective,” Leius said. “It’smost beneficial in areas where you can-not blast. Blasting is typically cheaper,but there are times that you may needto get something done right away, andthis allows you to start achieving pro-duction without having to go throughthe process of getting blastingapprovals.”

The process consists of drilling holesup to 2 ¾ in. diameter and loading theDa-mite expansive mortar in the hole.Over a matter of hours, the product setsand splits the rock or puts it in tension toease in the excavation process. “We have recorded Da-mitedeveloping strengths of 22,000 psi in 20 to 24 hours and in excessof 40,000 in eight days,” Daigh said.

In open cut sections, Leius said crews achieved better pro-duction rates in areas where they used Da-mite. “Some of therock was so hard that the breaker hammer bounced right off it.But the Da-mite product put the rock in tension and the hammeras substantially more effective,” he said. In addition, less

excavation was necessary because the pre-split rock allowed forstraighter walls.

In tunnel areas, crews drilled from the surface to the tunnelalignment in advance of tunneling operations to pre-split rock.The process allows a microtunneling machine to achieve betterpenetration or allows easier removal with a breaker hammer.

Another area in which the expan-sive mortar was beneficial was in anarea along the alignment that requireda junction to an existing clay tile sewerbuilt nearly 100 years ago. Originalplans had called for the junction to bebuilt farther south, but changes dictat-ed that the junction be made with thedelicate, hand-laid clay tile pipe.

“Excavating around the existingsewer required us to be very gentleduring the excavation – and that is dia-metrically opposed to how you normal-ly go at rock, which is aggressively and

with maximum force,” Leius said. “Therewere also concerns because this pipe car-

ried 12 million gallons a day of flow. Using the expansive mortar,we were able to increase our production over hand removalwhile still protecting the integrity of the pipe.”

With the help of an additional tool in the toolbox, crews are ontrack to completing the project despite the challenges of unfor-giving geology.

Over a matter of hours, the mortar sets and splits therock or puts it in tension to ease in the excavation.

Today’s tunneling projects are longer, in tougher geologicconditions and often feature smaller working spaces. Conveyor

designs for these conditions must take into account many parameters such as the bore diameter and type of TBM, muckchip size, abrasiveness of the rock, moisture content of the rockand the profile of the tunnel.

Customizing conveyor systems for these types of projectsoften requires new materials and technology. Increased optionsare allowing better management of load sharing as the amountof spoil varies on the conveyor, while the reliability of conveyorequipment can be increased by using materials such as ceramicand steel cable.

Greater ControlVariable frequency drives (VFDs) are one of the major

innovations to come to conveyor systems in recent years. VFDsare becoming the preferred control system over hydraulic couplings in order to better control acceleration during startup.The system actively sets the speed and torque that a drive contributes to the conveyor in both single and multiple drivesetups. In this way, a controlled startup is possible and belt tension is kept low to reduce stress and allow certain types ofbelts to negotiate tunnel curves.

While both VFDs and hydraulic coupling systems are used,VFDs are becoming more favorable due to a variety of innovations. “Variable frequency drives are more cost-effectiveand reliable and require less routine maintenance than hydrauliccouplings,” explains Butch Riffe, chief engineer for Robbins conveyor systems. The drive systems are much less expensivebecause they use AC three-phase motors, which require lessmaintenance compared to earlier DC motors. Newer systemsalso are digitized, so a separate frequency motor is not neededto control the torque supplied by each drive.

Since their power output is controlled, VFDs also are moreenergy-efficient than their hydraulic coupling counterparts.Hydraulic coupling systems are still used, mainly on single drivesystems and on shorter tunnels that do not require a boosterdrive. These coupling systems offer a smooth startup for thesimpler motors that operate on one speed only.

New MaterialsMaterials such as steel cable and ceramic are giving more

options for longer tunnels and can increase the driving force toreduce wear and tear on the system.

Steel CableSteel cable belt is becoming an important alternative to fabric

belt in recent conveyor systems. Steel cable has a higher strengththan fabric, and can therefore be used with more powerful drives.The higher power motors greatly reduce the need for booster drives on longer tunnels. Booster drives, which add power to thebelt along the tunnel length, can be difficult to install and are oftencostly to assemble and maintain.

Steel cable belt is currently being used on a large tunneling project in Liaoning, China. Two 26.3-ft diameter main beam TBMsare boring the Dahuofang Water Tunnel, a large reservoir diversion project consisting of two tunnels 10 and 12 miles long.Trailing behind the TBMs are two steel cable belt conveyor sys-tems equipped with multiple drive motors of 900 kW each (com-pared to a more typical 300 kW conveyor drive). The powerful drives eliminate the need for several booster drives. In fact, thetunnels are using only one booster drive each despite their extensive lengths.

Steel cable belt does have its limitations. The belt has high ten-sion capability and cannot be bent on sharper curves, making itefficient only for mostly straight tunnel paths. Fabric belt cannegotiate curves easily because it does not have the rigidity of asteel cable belt, although additional booster drives may be need-ed in curved areas. The cost per meter of fabric belt also is lessexpensive than steel cable belt, although the additional boosterdrives needed in most fabric belt systems often negate these savings. In addition, steel cable belt can be more difficult to splicethan fabric belt. Fabric belt, when damaged, can be repairedquickly with a mechanical fastener, while steel cable belt requiresa time-consuming weaved splice as well as vulcanizing.

CeramicDrive pulleys — the drums connected to drive motors that

power the conveyor — have traditionally been wrapped in a thin(1/2 in.) thick sheet of grooved rubber lagging in order to get abetter driving force from the motors. Recently, ceramic lagginghas been developed for drive pulleys. The new design incorpo-rates ceramic tiles into the rubber sheet to get a higher coeffi-cient of friction and therefore greater force, while reducing wearon the lagging. Ceramic lagging also can be hot vulcanized ontothe pulleys, which allows for better bonding to the drum of thedrive pulley. For these reasons, conveyors that feature ceramiclagging have a decreased tendency to spin or slip, which can

increase the wear on the conveyor belt.

Customizing the SetupToday’s muck hauling systems are

becoming more specialized for circum-stances such as tight workspaces, curvedtunnel paths and longer tunnels with lim-ited or no intermediate access. Thesetypes of solutions are making it possibleto use conveyors in difficult ground con-ditions and in areas where a small foot-print is vital.

Integration with the TBMBack-Up

Integrated conveyors allow furthercustomization of muck removal in tighttunnels where many simultaneous oper-ations need to be coordinated. In typicalconveyor systems, the tail pulley andinstallation window are located in thesame unit. This configuration protectsworkers as they install support rollers ina continuous fashion while the TBMadvances. From the TBM conveyor,another longer conveyor transfers muckto the tail pulley/installation window unitbefore the muck exits the tunnel on themain tunnel conveyor.

Integrated conveyor systems sepa-rate the tail pulley from the installationwindow, though both are still mounted inseparate frames along the backup sys-tem. The design only requires a shorttransfer conveyor between the TBMconveyor and the main tunnel conveyor,which frees up space in the tunnel andallows more room for integral operationssuch as tunnel lining and support.

Because of these advantages, inte-grated conveyors are ideal in tunnelsthat require ground support or otherspecial operations in a small workingarea. A current project in Pajares, Spain,is using an integrated conveyor systemprovided by Robbins along with a singleshield TBM in order to bore throughblocky, highly fractured ground. The tailpulley and installation window on theTBM’s conveyor system are separatedby 100 ft. The setup helps to free upspace in the tunnel for segment erectionbehind the TBM.

Crown Mounting While side-mounted conveyors are by

far the most common conveyor setup,crown mounting is an important option inmany tunneling situations. In small-diam-eter bores, there may not be enoughclearance in the tunnel for locomotivesand rail muck haulage if the tunnel con-veyor is mounted on the side. Crown-mounted conveyors also can be useful

when there are multiple adits that need tobe accessed from a main tunnel.

Crown mounting proved useful on theEpping to Chatswood Rail Project involv-ing twin tunnels in Sydney, Australia. Theparallel tunnels, driven by two 23.6-ftTBMs, required many drill-and-blastexcavated access adits between them.Because of the multiple side tunnels, acrown-mounted conveyor was used tofree up space on the tunnel floor. Thedesign proved successful, as the projectfinished ahead of schedule and achievedrecord advance rates.

Negotiating CurvesCurved tunnel paths are one of the

biggest challenges presented to muckhauling systems. Self-adjusting curveidlers, patented by Robbins, help to solvethe problem by pivoting to accommodatechanging load tensions around curves.The pivoting action also is favorablebecause it does not unnecessarily alterthe carrying capacity of the conveyor orthe belt tension. Self-adjusting curveidlers were used successfully in thecrown-mounted position for the Eppingto Chatswood conveyor system (aRobbins supply), as more than 80 percentof the tunnel path involved curves.

New developments in curve idlers havemade them even more vital for conveyordesign. Robbins recently decreased theweight of the carrying idler assembly,which improves worker safety by makingthem easier to lift. “The reduced weightmakes it easier for workers to installidlers through the installation window,which means less possible back injuries,”Riffe says of the improvements.

Designing for LongerTunnels

TBM projects are becoming moreextensive, and the AMR Project in Indiais no exception. The project, to start in2007, includes the longest TBM-driventunnel without intermediate access in theworld. The tunnel design presents uniquechallenges for conveyor development.

“We will have to do one of two things,”explains Riffe. “Either we will have tomake the length of the conveyor longerthan any we have ever provided, or wewill break the conveyor up into shorterflights.” The shorter sections of conveyorwould require that the belt storage cas-sette be located inside the tunnel. Largerolls of belt would also have to be addedinside the tunnel, requiring an effectivesystem of transportation.

SELL YOUR BUSINESS


There is an old and absolutely true saying "Success has many fathers, butfailure is an orphan." If you work for atunnel contractor long enough, sooner orlater you will work on a job which losesmoney hind-end over teacup, and has youwondering why you didn’t become a busdriver instead of an engineer or field manager. That is the nature of the busi-ness and the game.

This may seem a gloomy prospect for ayoung person just starting out, but if youhave nothing but success for a while, youmight get to thinking, as I did many yearsago, that this is pretty easy duty forsomeone as whip-crackin’ smart as youare. But the fact is that you don’t know forsure whether you are good, or just lucky.

Almost 43 years in this Sisyphean profession has taught me that, with all theagony, a bad job has many positiveaspects. Outfits that survive them areusually better for having had the experi-ence. When that brass-plated bitch of aproject does come along, and it surelywill, there will be some rather hard, butlasting, lessons to be learned.

You’ll find out that bad news is alwaysbelieved whether true or not, and travelsat the speed of mouths. There will alwaysbe some folks who have nothing at all todo with the job that speak with seemingauthority about how bad things are andwhy they’ll get worse. Even in your ownoutfit, or your joint venture, there will bethose who try to shine their own star withthe bloody shirt of a co-worker.

You’ll find out who among your co-workers you can count on in a "hot cor-ner", and who you can't. You’ll likely besurprised at who they are, and who theyare not. The folks who step up, put theirpersonal life on hold and willingly dowhatever is needed are the “stars oftomorrow”.

You’ll find out who your friends are, whothey are not, and understand better how totell the difference. You’ll appreciate thevalue of honest, open relations with yoursuppliers. When times are good again, andthey will be, be sure to remember that thestreet runs in both directions, and cut theones who stood by you a little slack.

You’ll find out that more than a few ofyour toughest problems are either self-imposed or worsened by your own deeds.You’ll find out which of your ideas about

the way things should be were good ones,and which probably never were. You arevastly better off when you are able to “recognize your own mistakes, rectifythem and move on. A credible claim identifies the “oops factor” up front.

You’ll find out that that many daysdon’t work out the way you had hoped and that perpetual optimists are doomedto perpetual disappointment. Sugar coat

the bad news and your career may beDarwinized. Messengers are usually shotfor being late, not for the news they bring.Don’t make too much of the good newseither; too much cake is bad for everybody.

You’ll learn the inestimable value of agood lawyer; one that isn’t afraid to tell youwhen you are wrong, but will work his buttoff for you when you are right. As in mostthings, you get what you pay for. Youwouldn’t want to have major surgery with alow-bidder doctor, and your contracts coun-sel is working to heal your company. Badjobs last forever, because the litigationlasts forever (or seems to). You’ll come tounderstand that the day the suits are filed,

both sides havealready lost.

Bad jobs are almost always late, andthere will be an artillery barrage of papermissiles, exhorting your outfit to do better right away or suffer unspeakablefiscal agonies. Requests for changeorders will probably be denied faster thanthe mail can get them there. When thepaper bullets are flying and the bracketednumbers are on every bottom line, it’salso a pretty good time to get betteracquainted with your priest, rabbi, imamor pastor. They won’t solve your problemsfor you but they will keep you aimed inthe right moral direction.

Oddly enough, some technical triumphsare accompanied by knee-deep oceans ofred ink. Applause dies away in moments,but scars last forever. Glory has no calories.I could be uncharacteristically cynical,and tell you that your first bad job won’tbe your last. It is a learning experience ifyou want to be taught.

Your kids and your spouse will toleratethe long hours, nights and weekendsaway from home, and the distractedthoughts if they know you love them andwill make as much time as you can forthem.

But someday, the day you thoughtwould never come, you’ll be looking atthat job in the rear view mirror, the boneswill have been picked clean and the blamelaid. Bloody, but unbowed, as WilliamErnest Henley declared in his poem,Invictus:

Out of the night that covers me, black asthe pit from pole to pole,

I thank whatever gods may be for myunconquerable soul.

In the fell clutch of circumstance I havenot winced nor cried aloud.

Under the bludgeonings of chance myhead is bloody, but unbowed.

Beyond this place of wrath and tearslooms but the horror of the shade,

And yet the menace of the years finds,and shall find, me unafraid.

It matters not how strait the gate, Howcharged with punishments the scroll,

I am the master of my fate: I am thecaptain of my soul.
