IN THIS ISSUE

The annual Superintendent's/OverseersConference is always one of the high-

lights of our program. This year marked the5th annual conference after completing thecircuit around the islands and returning towhere it originated in Maui. The conferencewas held at the Royal Lahaina Resort onSeptember 8 - 10, 2004.

Mayor Alan Arakawa opened the sessionwith a warm welcoming address andexpressed a deep appreciation for all thehard work and dedication that Countyemployees put forth. He stated that duringemergencies, it is the road crew that mustbrave trying conditions to affect neededrepairs. He also discussed the future plansfor the roads on Maui and some of theimprovements that they are looking forwardto accomplishing. We would like to thankMayor Arakawa for taking time out from hisbusy schedule to attend the conference andwelcome everyone.

After the Mayor's opening remarks, we gavea short presentation on our program andannounced some of our upcoming work-shops. We also presented the "BetterMousetrap" Award to Leonard Costa andJohn Prito from the County of Maui for theirStream Filtering Guardrails invention (seepage 3). We encouraged the counties toshare their great ideas or inventions withone another and promise to showcase themin our future newsletters.

Each county gave a presentation on some oftheir current projects and operations. Duringthese presentations, other counties offeredsuggestions on improving operations, givingexamples of how they handle similar situa-tions. Many of these exchanges of ideashave resulted in solving problems through-out the counties. A few of these include:

Maui County's use of Nextel phones as aconstant communication source betweensupervisors. This worked so well that OahuCounty has equipped their entire operationwith Nextel phones.

Hawaii County demonstrated their proce-dures to interview new and prospectiveemployees. Each prospective employeewas asked to identify tools necessary to

perform the tasks of their position. Oahu County applieda similar procedure to their interview process.

Two years ago Maui County had problems with largevehicles running over their storm drains, causing severedamage to the decking. Oahu County sent plans andspecifications on constructing a "chair" to reinforce thedrain decking to keep it from collapsing. Maui presentedtheir finished product this past year and have scheduledto do further construction on their storm drains.

Oahu County introduced the topic of "early to work" or"light duty" for employees out on industrial injury leave.This year Maui County tried it out and found that it helpsrehabilitate their employees so that they may return to fullduty earlier than scheduled.

The Big Island learned from applications in Maui thatwith proper installation plastic culverts can save signifi-cant life cycle costs.

Also included in the conference were technical tours tovarious baseyards and flood control systems in theCounty of Maui. Participants received a first hand view ofongoing and completed projects.

We at the Hawaii LTAP would like to thank all the partic-ipants and especially Eddie Emoto and the County ofMaui for planning and hosting a most successful confer-ence.

GOT A BETTER MOUSETRAP?

Problem:

We have some ancient, long time in existence, "pas-ture streams" in Upcountry Maui. These cross undersome of our narrow, highly utilized, vital country roads.Most of these streams, if not all, flow through privateproperty. Property leased, by the State, to private cat-tlemen. Water flows under our roadways through smallculverts that are, by today's standards, "substandard"to some degree. Such as being sized in a "functional-ly practical" way. Ergo: Instead of having one largeforty-eight inch culvert, it may be sized with two, small-er twenty-four inch culverts. These culverts wereinstalled years ago and will eventually need retro-fitting, to be more practical.Until then, we have someintermittent flooding prob-lems.

These pasture streams gen-erally flow constantly, with anincrease in volume flow whenit rains. With a hard, suddendownpour, these streamsmay "flash" flow, bringingwith it an assortment ofdebris. Sticks, leaves, grass, and small branches fromthe pastures. These get intertwined in the flash flowand will quickly and suddenly clog small culverts.Sometimes clogging well inside the culvert, making ithard or impossible to remove, until the rain subsides.Water would then flow over the roadway, sometimesbeing two feet deep in areas. Cars, trucks and moreimportantly emergency vehicles cannot pass. A vital

road has to be closed. We now have a temporary haz-ard. If people try to cross the area, they get stalled inthe deep water. How can we better cope or lessen thisclogging tendency?

Solution:We noticed that the adjacent guardrails would do agood job of stopping and filtering major debris. It waseasy enough to clean the debris off the backside ofthese guardrails. Beats crawling into small culverts. Itwas thought that if we placed guardrails across thestream, upstream of the culverts, it may filter thedebris before it went into the small culverts. It was alsotheorized that, if this happens, we may possibly lessen

the chances and number offlooding instances. Clogswould be easier to clean outin general. With new accessgates created along the prob-lem areas, and with the per-mission and buy-in by theadjacent landowners, wegave it a try.

We placed guardrails, appro-priately spaced, to allow con-

tinuous water flow, but close enough to catch majordebris before it entered into the small culverts. If theguardrails get severely clogged, water can still flowover or around the rails. It does, though, catch and fil-ter out the initial flash of debris. It works for us. We doneed to monitor and clean the rails regularly. But it hasdefinitely lessened the flooding incidents in the areaand the severity of clogs inside the small culverts.

Editor’s Note: The LTAP Director challenged our readers to submit descriptionsof devices or machine modifications they invented for improved operations sothat everyone can gain from the fruits of local creativity. Our feature for this quar-ter was submitted by the County of Maui. We look forward to the other countiessubmitting their devices to be featured in future issues.

Self Consolidating Concrete - A New Level ofPerformance

Self Consolidating Concrete (SCC) is a special concretemix designed to flow under its own weight, so it can beeasily placed, without additional mechanical compaction,i.e. vibrators, into complicated or narrow formwork. Thecritical aspect of this technology involves attaining ahighly fluid mixture while preventing segregation of theconcrete components. SCC was initially developed inJapan during the 1980s.

Sounds great doesn't it? But, can it be produced inHawaii?

Yes! Our local ready mix companies have diligentlydeveloped concrete mix designs to make the 'spread'.No, not a wager, but a method of measuring flowability ofthe SCC mix in lieu of the traditional slump test.

What makes it SCC work? Aggregate sizes and grada-tion plays an important role in achieving a good SCC mix.The admixtures, viscosity modifiers, high range waterreducers, and superplasticizers enhance the mix to flowand not segregate.

The FHWA, HDOT, and CCPI recently held a joint work-shop in August to share the latest technological develop-ments in the design and application of SCC. Attendeesheard from highly regarded and knowledgeable people inthe field of SCC: Myint Lwin, Director of BridgeTechnology FHWA Washington; Charles Nmai, ChiefEngineer at Degussa; Dr. Anton Schindler, AssistantProfessor Auburn University; and Steve Schultz ,Technical Representative at Degussa. Seeing is believ-ing as the attendees also had the opportunity of observ-ing what a SCC mix looks like from a ready mix truck dur-ing a demonstration pour on-site.

Significant research in the design and application of SCChas already been conducted in the U.S. Sponsoringnational industry organizations and companies includeACI, PCA, and PCI along with Degussa, WR Grace,Euclid Chemical, and Sika.

Although the workshop focused on the use of SCC indrilled shafts, the potential benefits are untapped asJapan found out; the intent of the workshop was also toprovide enough tools and technical information to allowengineers and contractors to find more beneficial appli-cations.

Congratulations to the Hawaii Department ofTransportation, Highways Division Kauai District, an

Honorable Mention winner of the 2004 Federal HighwayAdministration/Federal Transit AdministrationTransportation Planning Excellence Awards.

The Hanalei Bridge Remove/ Repair/ Replace MetalMembers project on the Kuhio Highway in Kauai, Hawaiibegan in 1972 with a proposal by the Hawaii Departmentof Transportation to entirely replace the aging one-lane,single span, steel truss bridge with a modern multi-lanebridge. The Hanalei project changed direction as a resultof active community involvement for over 25 years. Theadopted design maintains the historic one lane bridgeand replaces the original truss with similar members.This project utilizes a context-sensitive solution for thisbridge, which is a treasured landmark that exemplifiesthe rural character of the North Shore of Kauai.

The criteria for reviewing the nominations for the awardincluded: innovation, intermodalism, partnerships, sus-tainability, equity, demonstrated results and replicability.The 2004 Transportation Planning Excellence Awardsrecipients went beyond the standard practices and incor-porated truly innovative and extraordinary efforts into

their transportation planning processes. The bar was setvery high.

Award recipients were honored on July 25 during the2004 Joint Summer Meeting of the Planning, Economic,Environmental, Finance, Freight and ManagementCommittees of the Transportation Research Board inPark City, Utah.

During a typical highway design and constructionprocess, there is a need to assess the condition of

existing culverts, cross-drains, and under-drains. This isespecially important for the small diameter pipes underhigh fills and retaining walls that cannot be inspectedmanually. Use of the Rovver® 600 has allowed our high-way engineers to make "fact based" decisions in eitherreplacing these pipes or accurately identifying the loca-tions for rehabilitation using trenchless technologies. Thegeotechnical engineers have utilized the down-holecapabilities of this tool for verification of newly installedslope stability measuring devices, and to assess existinginstallations. The ability to position the camera into con-fined, normally inaccessible or unsafe areas allows ourconstruction inspectors to verify structural reinforcementspacing, placing, and clearances for quality assuranceand control. The ability to push the camera into openingsas small as 2-inches allows for the inspection of most in-place drainage systems and naturally occurring features.The data collected once can be shared, with all of the pri-mary stakeholders, many times throughout the projectlife-cycle.

The Rovver® 600, manufactured by Everest VIT, Inc., isa self-propelled remotely operated motorized crawler.The modular component design provides capability toinspect inside pipes with diameters ranging from 2- to 36-inches. The Rovver can be outfitted with either an axialcamera head for down-hole and push pole applicationsor with a pan or tilt camera head using a fully articulatingmanually focused low-lux lens for larger pipes. Boththese lenses provide digital video and digital still images.The camera heads can operate independently of theRovver crawler assembly.

THE ROVVER APPLICATIONS

Rovver was used to assess the condition of all majorpoured-in-place box culverts installed in the 1930s atAlder Camp Road in the Redwood National Park inCalifornia.

The use of Rovver tremendously helped the project teamin their overall hydraulic analysis and condition assess-ment of the existing structures. It was determined thatsome of the box culverts did not require replacement asinitially estimated, resulting in significant savings.

The Rovver was also used to assess the condition of a24-inch culvert on the Swamp Creek - East Project locat-ed near Libby, Montana. The inlet of the pipe was drywhile the outlet was producing a steady stream of water.Richard B. Jackson, Geotechnical Engineer, MontanaDOT was aware that the culvert is being fed by collectorpipes that ran parallel to the highway. However, the exactlocation and number of collector pipes, as well as theoverall condition of the entire spring collection systemwas not apparent to Montana DOT engineers.

The use of the Rovver provided the Montana DOTdesign-staff the condition assessment of the culvert andthe precise location and number of collector pipes feed-ing into it.

ROVVER AVAILABILITY

The Rovver is available for use, free of charge, to anyState, County, or City Transportation Department as partof Technology Deployment Program of Western FederalLands Highway Division in Vancouver, WA. The Rovvercan be requested through your local LTAP/TTAP centeror directly through WFLHD (Amit Armstrong, 360-619-7668).

The Hawaii Local TechnicalAssistance Program (HLTAP)would like to express ourheartfelt mahalo to RussellSugano who has been amember of our AdvisoryBoard since 2001. He hasbeen instrumental in assistingHLTAP with workshops for theCounty of Kauai and our 2003National LTAP-TTAPConference. We would like towish him all the best in his

retirement and future endeavors.

The following was written by Carol Suzawa (Russell’ssignificant other) & Alex Pascual from the County ofKauai:

A “Celebrate Russell Sugano Retirement” golf tourna-ment and surprise party was held on September 12,2004 at Hanamaualu Cafe. However, the surprise wason the 140 guests because Russell arrived earlier thanmost of them. Nevertheless, the evening went on with amedley of comedy.

Speakers at the affair were: Howard Uohara, a person-al friend who chaired the tournament, Jeff Isokane, aclassmate back in their childhood days, Cesar Portugal,Engineering Division Chief of the County of Kauai, Allan"Otto" Miike, a fellow golfer and personal friend, CarolSuzawa, Russell's significant other, older brother AlbertSugano and Laurel Loo, County Attorney.

What really touched Russell's heart was a presentationof a certificate that was read by County Council AttorneyAmy Esaki. The recognition certificate was sponsoredby the entire County of Kauai Council.

The certificate stated:

“The Council of the County of Kauai Hereby presents thisCertificate to Russell Sugano for his thirty years of ded-icated service to the County of Kaua'i. Russell began hisillustrious career with the County as a Civil Engineer IIIfor the Department of Public Works Engineering Divisionin September 1974. He was promoted to become theHighway Construction and Maintenance Superintendentfor the Highways Division in 1978 and served in thatcapacity until August 31, 2004. He also served as the

Deputy County Engineer from 1986 to 1988.

Under Russell's leadership the County completed thereconstruction of Rice Street which expanded the twolane street to a four lane, removed all of the County'sunderground storage tanks in a timely manner, andreconstructed the 'Oma'o Bridge and award winningHo'onani Bridge in Po'ipu. Russell was also in charge ofthe County's Annual Island Wide Road ResurfacingProgram. He was a key member of the County'sEmergency Response Team during two of this County'sworst hurricanes, 'Iwa and 'Iniki. Together with JohnApana, Russell ensured that Kaua'i roads were prompt-ly cleared of debris to enable access and safe passagefor emergency vehicles and the public.

Russell was the County's unofficial complaints officer ashe fielded numerous public complaints courteously andprofessionally, ranging from potholes, guardrails, fallingmangoes, overhanging branches, establishment andremoval of bus stops, overgrown hedges at street cor-ners, and many more. Despite his workload, Russell wasalways cheerful and ready with a joke for the day, whichhe did not hesitate to share with his coworkers.

The Council sends its sincere appreciation to Russell forhis contribution to this County and congratulates him onhis retirement.”

Russell retired on August 31, 2004. Some of his activi-ties in the past months have been painting his house,helping his brother build a green house, fishing, golfingthree days a week, babysitting, consulting work, and ….oh let's not forget, Russell always has a Joke a Day!

Program Manager’s Noteby Juli Kobayashi

Whew! This quarter has been a whirlwind ofactivities for the Hawaii LTAP! We have held10 workshops with a total of 18 sessions, weattended several conferences and we alsohired 2 new student assistants (see page11).

Of special attention this quarter were the HotMix Asphalt Pavement Maintenance andRehabilitation workshop and the Erosion &Sediment Control workshop. These work-shops had such a large interest that we wereable to train 475 participants. At the Erosion& Sediment Control workshop we trainedconstruction, design and maintenance per-sonnel from the DOT, counties and the pri-vate sector. We would like to credit DeanYanagisawa (HDOT) for taking the lead inthese courses and the instructor BrianRoberts for his outstanding efforts to trainthe participants on the best managementpractices in erosion and sediment control.

In July we attended the National LTAP-TTAPConference in Bernalillo, New Mexico. Itwas a wonderful conference and we learneda lot of new and innovative ways to improveour program. We especially appreciated thesession where peers from the other LTAPcenters critiqued each other’s newsletter.We were able to pick up some very usefulideas and will try to incorporate them in ourupcoming issues.

The month of September has been full ofactivities with the annual Superintendent/Overseers Conference (see page 1-2), theSubsurface Utility Engineering (SUE)Briefing, the Utilities CoordinationConference and the Governor's HighwaySafety Association Meeting. All these valu-able events have kept us very busy and wewould like to take the time to really thank allthe exceptional individuals who coordinatedthese important training sessions for theState of Hawaii.

HAWAII LTAP NEWS

The Hawaii LTAP would like to welcome our new student assistant, KevinKuba. Kevin is a sophomore majoring in Mechanical Engineering. In hisspare time he enjoys hanging out with his friends, playing soccer, and liftingweights. Kevin was an active member of Hilo High Key Club and participat-ed in events for the Peanut Butter Ministry, Recycling Center, and SpecialOlympics. In the future, he hopes to obtain a position working in the aviationfield.

Ending the second quarter was the "Rock Slopesworkshop". Instructors Duncan Wyllie and Norman

Norrish imparted to the participants the knowledge andskills to determine the appropriate level of geotechnicaleffort needed for both design and stabilization of new andexisting rock cuts.

Beginning the third quarter was the much anticipatedAsphalt Series II: "Hot Mix Asphalt PavementMaintenance and Rehabilitation". The workshop washeld on Kauai and Oahu. Lead instructor Steve Muenchwas joined by fellow University of Washington professorJoe Mahoney as they took an in-depth look at HMApavement rehabilitation which included the identificationof pavement distress, non-destructive testing methods,repair strategies and overlay design. The demandexceeded the available space for this course. We hopeto repeat it next year.

In July, Mark Hood presented participants with methodsfor implementing effective, low-cost safety improvementstargeted at high crash areas in a workshop entitled the"Roadway Safety Improvement Program". One attendeenoted that "The Roadway Safety Improvement Programwas very informational and presented some practicalsolutions for roadway safety problems that we can imme-diately implement to reduce accidents on our roadwaysystem."

We assisted the Hawaii Department of Transportationwith the coordination of the National Pollutant DischargeElimination System (NPDES) workshop entitled "Erosionand Sediment Control for Highways" in Mid-August.Instructor Brian Roberts provided participants with athorough understanding of the principles of erosion andsediment control and how they uniquely apply to highwayprojects.
