ENGINEERING COLORADO QUARTERLY 3

Green Infrastructure

roughout my career as a civil engineer, i have worked on manyprojects that resulted, at least in part, to a product of sustainableinfrastructure. e sustainable results were hit and miss because theprime focus was not specifically on sustainability. without guidelinesand direction, we got what we got. we have been aware of the u.S.Green Building Council and the LEED program for buildings. erewas no equivalent system for horizontal infrastructure projects.

in 2010, three organizations came together to establish the institutefor Sustainable infrastructure (iSi). e goal of the AmericanCouncil of Engineering Companies, the American Society of CivilEngineers and the American Public works Association was to developa rating system to examine sustainability over the life of an infrastruc-ture project. Environmental, economic, and social factors are thebottom line of sustainability. Envision is the result of the effort. OnSeptember 1, iSi began accepting applications for projects to be ratedwith Envision. e rating system is performance-based and adaptablebased on project size and complexity, allowing agencies to use it forthe very largest projects, while allowing its use for smaller projects.e system also includes an option for self-assessment.

iSi is a non-profit organization tasked with developing andadministering a sustainability rating system for north Americaninfrastructure. e iSi mission is to help change how we think aboutbuilding sustainable infrastructure. iSi found over 900 sustainabilitytools were used around the world. e institute for Sustainableinfrastructure decided to combine their tools with the Harvarduniversity Graduate School of Design’s Zofnass Program forSustainable infrastructure. EnvisiontM is the result of this collabora-tion. EnvisiontM can be used on any size project. it is the tool forevaluating and rating the community, environmental and economicbenefits of all types of infrastructure projects. e rating systemevaluates, grades, and gives recognition to infrastructure projects thatuse transformational and collaborative approaches to assess thesustainability indicators over the course of the project's life cycle.

President’sView

iSi wanted to develop a multi level rating system that would workon diverse types of infrastructure projects from utilities to transporta-tion and water. EnvisiontM differs from LEED as it is not only basedon criteria but also performance of the project. Projects can betracked from the planning stage through design, construction andmaintenance. Envision™ is new and it is expected to receive a greatdeal of user input. we will learn more about the skill sets requiredof those best qualified to guide infrastructure projects to successfullevels of sustainability. Currently, iSi is offering Provisional Creden-tialing Certificates (Env Pv) for the period ending December 31,2013, after which re-application and testing may be required toobtain the Env SP (Sustainability Professional). Besides creden-tialing, iSi also offers training.

Here are the requirements from iSi for Env Pv:

• Successful achievement of a four year degree in engineering, architecture, the sciences or related curriculum;

• Completion of iSi conducted computer-based courses on Envision™ and its use;

• Successful passage of an online examination on the use of Envision™ of 75 questions with a successful score of 75%;

• Submission of all applicable fees.

instructions and online application form are available at http://sustainableinfrastructure.org/.

MaintainingMomentum

Coloradoans have been faced with many life-changing events thissummer – the wildfires, the shooting of Denver police officer at theCity Park Jazz Festival and the Aurora eater shooting. we offerour sympathies to all affected by these tragedies and our thanks toall of the emergency responders and the heroic efforts of everyoneinvolved. it is times like these that despite our shock and disgust,we come together to offer support and aid. Partnering with organ-izations and agencies to offer assistance is an important directive ofACEC/CO and a reoccurring theme of this issue’s articles.

Our Southern Colorado Committee sprang into action to offer ex-pertise and guidance to the communities affected by the waldoCanyon Fire as you will read on page 7. All those affected by fire-impacted areas are vulnerable to many emotional roller coasters andthe technical challenges that follow, such as mudslides, erosion con-trol and stormwater issues with the pending monsoons. ACEC/COprovided our members throughout the state with pertinent informa-tion and protocols to them as they began working with the affectedcommunities to provide emergency services. not only is this infor-mation valuable as it applies to natural disasters, but for engagingman-made emergency situations such as peer reviews of faulty struc-tures that an agency might request.

Many large and complex projects are requiring both technical andfunding innovation in order to get them built. we will be seeingmore Public-Private Partnerships (P3) formed to deliver transporta-tion projects for agencies such as CDOt and rtD and future waterinfrastructure projects. Buck Beltzer, P.E., Esquire and ACEC/CO’sGeneral Counsel, addresses the challenges consultants face when sub-mitting proposals in this format on page 5.

Although providing sustainable and cost-effective projects for theirclients comes naturally to engineers, measurements of sustainabilityhave been instituted, such as through united States Green BuildingCouncil’s LEED® program and now by the institute of Sustainableinfrastructure (iSi). in 2011, the American Council of EngineeringCompanies (ACEC), in partnership with the American Society ofCivil Engineers (ASCE) and the American Public works Association(APwA), formed the new organization. iSi has designed a new rat-ing tool, Envision™, that is available to public agencies which willhelp them assess the sustainability features of their infrastructure proj-ects. ACEC/CO, along with the Colorado chapters of ASCE andAPwA, have been working with consulting engineering firms andtheir governmental clients in piloting this new tool. So far the re-sponse has been favorable and we will be highlighting case studies infuture issues of our Ezine. On page 9, you will read more about offersEnvision™ and the trainings offered by iSi.

ACEC/CO is fortunate to work with many strategic partners thathelp the engineering profession and design and construction industryto provide decision makers with the information they need to makethe important decisions necessary to improve our quality of life. isquarterly Ezine provides insight into our strategic partner, velmaLane, senior vice president for professional liability insurance withvangilder insurance Corporation. For many years, velma has assistedconsulting engineering firms and their clients in both the public andprivate sectors to provide good contract language and general businesspractices that benefit all parties.

Our annual salary survey questionnaire will be out to the member-ship in mid-August. is valuable tool is used by agencies such asCDOt in determining fair and reasonable salaries of the consultingengineering firms that they hire. i strongly encourage our member-ship to complete the questionnaire – the more firms that participate,the stronger the data. e survey will be distributed in October.

By working together, we accomplish what is a win-win for the public,governmental partners, ACEC/CO member firms and the industryas a whole.


ACEC Colorado Reports Findings of EnvisionTM 2.0 Pilot Studies

By Howard Schirmer, Jr. PE, FASCE - President, Transnational Associates, Inc.

ACEC of Colorado (ACEC), the Colorado Section of AmericanSociety of Civil Engineers (ASCE) and Colorado Chapter of theAmerican Public works Association (APwA) combined forces todo an early testing of the institute for Sustainable infrastructure’s(iSi) Envision 2.0, a sustainable infrastructure rating system onprojects in Colorado. the findings have been relayed to iSi forreview and incorporation in the next version of Envision which isunder development. Few, if any, projects were evaluated usingEnvision 2.0 at the time of ACEC's work so ACEC's efforts wereuseful and very much appreciated.

ACEC and APwA made available information gathered from theirproject award programs. Approximately 35 projects were evaluatedas possible candidates and four different project types and sizeswere selected. they were:

woodmen road/Academy Boulevard interchange – ColoradoSprings, Colorado (transportation project) - Owner/client – Cityof Colorado Springs; Project designer – urS Corporation

Little’s Creek Drainage improvements - Littleton, Colorado (stormdrainage project) - Owner/client – City of Littleton and urbanDrainage and Flood Control District; Project designer – MullerEngineering Company, inc.

Gold Camp tunnel – teller County, Colorado (geotechnicalrestoration project) -Owner/client – teller County; Project de-signer – Shannon & wilson

rio Grande recycle Center – Aspen, Colorado (environmentalproject) - Owner/client – City of Aspen; Project designer – Cityof Aspen

interviews with the project designers were held and numericalscores generated, even though the focus of the pilots was not onscores but on the scoring and evaluation process. Difficulties inunderstanding the meaning, intent, and application of criteria werenoted. Envision 2.0 has 60 criteria that were rated, if they wereapplicable.

e pilot studies findings were:

• All projects successful in community coordination• High score correlated to high budget• wide range of scores ranging from 299 to 82 out of

a total possible of 750 points• Complex for small projects• Best if initiated early in project cycle• Level of achievement subjective• Procurement constraints• need to show return on investment• Design engineers willing in all cases to have their

project evaluated

e participant's feedback included:

• Piloting increased sustainability awareness• too much emphasis on climate change• Some of the elements that required mandatory

inclusion not applicable• Added value of certification uncertain• use of rating system driven by client • innovative approaches/material risky for design

professional• useful tool for planning and designing projects

Forty nine detailed comments and recommendations were made in the report. if anyone wants a copy of the report, it is availablethrough the ACEC office..


MeetDenver Zoo’s George Pond

MEET features a strategic partner of ACEC/CO. In this issue weintroduce you to George Pond, Vice President for Design and CampusManagement at Denver Zoo. He shares his perspectives on literally “writingthe book” on sustainable design for animal environments, working with en-gineers to achieve his vision, and his passions for architecture and evolvingthe Zoo experience.

ACEC/CO: Tell us about your background – why did you choose tobecome an architect?

GP: i didn’t always aspire to become an architect. Actually i went toKenyon College, a liberal arts college, and studied English Literatureand had a general liberal arts education so i came out very wellrounded, but not pointed in any one direction. Around that time,though i really started to identify a desire to be involved in design,landscape architecture specifically. i didn’t actually pursue it, though.immediately after graduation i went out into the workforce and soldoffice supplies for a wholesaler for a while. e first thing i did iscrack open the company’s catalogue and bought all the draftingequipment. So that was about the time i decided to take it seriouslyand figure out what was going on. i then came out to Colorado forarchitecture school at the university of Colorado-Denver and endedup with two master’s degrees, one in architecture and one inlandscape architecture.

ACEC/CO: What led you to working at a zoo and when did you jointhe Denver Zoo team?

GP: well, interestingly i happened to be at a transition point shortlyafter getting out of school and doing some work on my own. i waslooking for work in 2000 and the zoo job came up. ey werelooking for someone with a blend of design and constructionexperience and at the time that’s exactly what i had. So i came downand interviewed with Craig Piper, who is now the zoo’sPresident/CEO, but is also an architect and zoologist. i was extremelyinterested in the job. it sounded like a fun job, and it’s also becomean incredible opportunity for me to be involved in, both constructionand design in a very dynamic place, with professional people doingincredible work.

ACEC/CO: How has your work changed/advanced during your tenure?

GP: when i came to the zoo, the Planning Department was verysmall and i was personally involved in a lot of on-site managementwork and served as a liaison to the design functions. Over time i’vetaken on more and more responsibility and we’ve had the opportu-nity to do a number of great things. we’ve expanded the amount ofwork we do in small projects, taking care of design and constructionfunctions for all of the departments. i think one of the things i’mmost proud of is how we made sustainability a functional part ofthe zoo and we really led that in the Planning Department.

ACEC/CO: When did you begin to focus on new energy and systemsthat would literally write the book on sustainable design for animal en-vironments?

GP: Sustainability was not a foreign concept for people at the zoo,but i think we in the Planning Department really made it a priorityof all of our design projects and how we were looking at what wereally could become at the zoo. i started that immediately and iwould say in 2004 or 2005, when we really started to design toyotaElephant Passage, is when we started to latch on to even bigger ideasthat now have become these new energy ideas, like gasification.

A lot of groundwork for sustainability was already laid when we as-pired to do something as crazy as create an entirely new waste-to-energy system that no one’s ever done before. in 2004 we probablydidn’t realize exactly that we were going to do that, but we startedto take the bait and say, “Yeah, this would be important and let’s seeif we can follow it.” we really haven’t stopped. we’ve just continuedto take steps and build momentum to the point that what we’redoing now is literally groundbreaking.

Continued on next page.


ACEC/CO: What did you find most compelling in working with eRMH Group when designing the Toyota Elephant Passage?

GP: i think the most compelling aspect of working with e rMHGroup was how invigorated and how excited they were aboutworking not only on a unique animal exhibit, but in working on thesustainability aspects of that as well. ey came in very excited andmaintained that level of excitement and professionalism all the waythrough. it’s probably not surprising that a zoo exhibit is very com-plicated and has a different set of parameters for an engineering firmto come into and have to apply their expertise. Some people orgroups can be taken aback by that, it’s outside of their comfort zoneand it doesn’t fit within the normal way they think about applyingtheir engineering skills. e rMH Group absolutely relished theuniqueness and the oddities that come with zoo design and theinnovation and excitement of something new like gasification.

ACEC/CO: Did the work on this project stimulate new thinking forother areas within Denver Zoo that are targeted for updates or newdevelopment?

GP: Absolutely. During this project as we started to get into theseadvanced levels of thinking about sustainability as a function ofdesign and of operations for what was going to become ten acres forour institution, we started things like discussing product procure-ment. right now we’re actively looking at literally everything thatwe buy, how do we affect our global footprint through the thingsthat we buy. at’s all a part of this project and gasification and it’sgoing to change the way that we do things throughout our zoo. itwas also during this time that we were inspired to be the first zooever to become iSO-14001 certified, which is a very rigorous sus-tainability standard. if it wasn’t for the work we were doing on toyotaElephant Passage we wouldn’t have attempted to achieve that. at’salso the standard that is applied to the entire operation of the zoo.So in large measure the effort of design and thought and executionof sustainability initiatives in toyota Elephant Passage has changedthe entire zoo.

ACEC/CO: What were the greatest challenges in designing and buildingthe Toyota Elephant Passage?

GP: ere were so many challenges, but the greatest challenge,perhaps, is the level of coordination necessary to consider all theaspects you need to and get them right. How do you sort out all ofthose things? How do you correlate them and see where everythingis interconnected and make sure you’re taking care of them all? atbecomes the greatest challenge. For sure, everyone as a designconsultant or a contractor or subcontractor or a stakeholder in thezoo, from some department, is used to looking at the world withtheir relatively narrow view of what’s important to them. is is thetype of project that really forced everyone to get outside of that view,outside of their comfort zone and realize how many things werelayered up and affecting each other so all of the participants had tochallenge themselves to put someone else’s shoes on and understandthe project from another aspect, we have a much richer and successfulexhibit because of it.


“...the effort of design andthought and execution of

sustainability initiatives inToyota Elephant Passage

has changed the entire zoo.”


ACEC/CO: Are there any lessons learned that you can pass along toother zoo operators that might be considering projects similar in nature?

GP: i think this was a project where we decided to get very seriousabout allowing the process of design and construction to get verymessy, to involve a lot of people, all those stakeholders, and to makesure we were accountable at a very detailed level to all of thesegroups. at was not exactly how we used to do it. it’s a way of de-signing that we’ve been moving up to for 10 or 15 years, but it reallykind of matured in this project. i would say the biggest lesson is thatalthough that was very difficult to do and took some resources andcommunication and caused some headaches, perhaps, we have amuch better project because of it. So if you’re willing to get messyin the design process and really stretch to make sure you’re account-ing for all of the details and all the stakeholders and really trying toset a bar for all of the different levels of a project, if you really putin the hard work the outcome can be much better than expected.

ACEC/CO: How do you see the zoo experience changing in the future?

GP: i think the biggest thing that toyota Elephant Passage does forour zoo, and i think this will change zoos all over the world in thefuture as well, is the rotational aspect. when you come to the zooyou’re going to have a great experience, but what exactly you’re goingto see will be somewhat of a surprise. it’s a rotational exhibit complexwith multiple species that can be around you in dynamic ways andcan be different from moment to moment, from day to day, fromweek to week. at means when i visit toyota Elephant Passage i’mgoing to see something new every time i come. if you come backtomorrow or next week you’re going to have a great experience, butit’s going to be a completely different experience. i think that rightnow as we’re going through our master plan process that’s exactlythe type of zoo we’re envisioning. it’s not that i know when i comehere i know i’ll see this on my left and that on my right. All i knowis i’m going to have a fantastic experience and i’m going to see an-imals and i’m going to feel inspired. i think this concept will bepicked up by other zoos and i think it will change the future of zoos.

ACEC/CO: What are the top three things people may not know aboutthe Denver Zoo?

GP: at we serve almost two million people a year and are the mostattended cultural attraction in Colorado. at we work in over 50countries in the world doing conservation work for habitats andspecies. And that we’re the greenest zoo in the world. i think thatpeople realize that we’ve done a lot of sustainable things, but i don’tthink they understand those things put us at a level beyond anyoneelse out there.

“When you come to the zooyou’re going to have a great

experience, but what exactly you’re going to see

will be somewhat of a surprise.”

George Pond is the Vice President forDesign and Campus Management atDenver Zoo; he is responsible for oversightand execution of the zoo's MillenniumMaster Plan, including the construction of new exhibits and facility improvements,management of grounds and horticulture,maintenance of all existing facilities, aswell as the zoo’s sustainable initiatives.

is year the ACEC/CO’s Expert witness and Ethics Committee has decided to teamwith ACEC/CO’s Energy Committee to present an ethics seminar about hydraulicfracturing. without doubt, the process of hydraulic fracturing has created consider-able media controversy with respect to oil and gas production activities and economicdevelopment as compared to community and environmental impacts extending allthe way to worldwide, geopolitical implications. For the purpose of this seminar,ACEC/CO will concentrate on how civil engineers can participate in this activity inan ethical and responsible manner.

Hydraulic fracturing or “fracking,” as the media prefers to call it has been around since1949. A relatively new technology called horizontal drilling uses fracking, which dra-matically increases the well’s production. is is a fairly new approach to drilling andproducing oil and gas reserves from “tight” geological formations such as shale. insimple terms, deep wells are drilled with long horizontal components in geologicalformations that have low hydraulic conductivity. ose drill holes are then pressurizedin order to fracture the rock and inject sand into those fractures allowing the oil andgas to flow and be recovered by the well. Modern-day hydraulic fracturing procedureswere established in the 1990’s and have become widespread in the last ten years. Sincethat time, the amount of oil and gas production in the united States has increaseddramatically along with the inevitable, alleged negative health, safety and public wel-fare impacts. Given below are brief discussions of the most important impacts asso-ciated with the increased oil and gas exploration and hydraulic fracturing.

Economic Impact

ere are two distinctly different aspects of economic development associated withhydraulic fracturing; the economic impacts associated with the process itself, and therelated economic impacts of having additional supplies of low cost energy. Givenbelow is a listing of just some of the positive economic impacts associated with hy-draulic fracturing:

One million new jobs created in the u.S. in the last ten years.

u.S. domestic oil production has grown by 25% in the last four years.

u.S. oil imports have dropped from 60% of u.S. needs in 2005 to 40% of u.S. needstoday.

u.S. domestic natural gas production has increased by 40% in the last five years whilethe cost of natural gas has decreased from more than $8.00/million btu to less then$3.00/million btu.


Ethical Issues Associated with Hydraulic Fracturing

By Dr. Gary S. Brierley ACEC Expert Witness & Ethics Committee and Kirsten Young, Member ACEC Expert Witness & Ethics Committee

Last year, the Expert witness and EthicsCommittee expanded its ethical “horizons” by

sponsoring a seminar featuring ethical consider-

ations associated with large regional projects.

at seminar focused on the broader aspects of

ethical behavior as discussed in the July, 2006

version of ASCE’s Code of Ethics as shown

below:

• Engineers should be committed to improvingthe environment by adherence to the principlesof sustainable development so as to enhance thequality of life of the general public.

• Engineers shall hold paramount the safety,health and welfare of the public and shall striveto comply with the principles of sustainable de-velopment in the performance of their profes-sional duties.

• Engineers shall recognize that the lives, safety,health and welfare of the general public are de-pendent upon engineering judgments, decisionsand practices incorporated into structures, ma-chines, products, processes and devices.

• Engineers whose professional judgment isoverruled under circumstances where the safety,health and welfare of the public are endangered,or the principles of sustainable development ig-nored, shall inform their clients or employers ofthe possible consequences.



related economic impacts can be summarized as follows:

Dramatically reduced costs for home heating for households that have access tonatural gas.

Huge positive impacts on the generation of electricity with the cost of electricitygenerated with coal as compared to gas dropping from more than 4¢/kw to less than2¢/kw.

Significant positive impacts on manufacturing and chemical production activities inthe u.S. numerous chemical and manufacturing companies have announced plansto open new facilities here in the u.S. as a result of low cost energy and fuel stocks.ere are already automobiles powered by natural gas instead of oil derivatives.Stations selling the natural gas exist in several areas, one of the most recent being Gree-ley, Colorado.

Although there is no doubt about the positive impacts of hydraulic fracturing as de-scribed above, these positive impacts do not exist without potentially negative impactsto the community and the environment.

Community Impacts

ere are very significant short-term construction impacts associated with oil and gasexploration and hydraulic fracturing. e creation of a drill pad site involves roads,pits, storage tanks, drill rigs, dust, noise, 24-hr construction and drilling activities, vi-sual impacts, truck traffic, etc. Clearly, anyone living near one of these sites wouldnot be pleased as a consequence of those impacts and it would be only natural forthem to expect and/or to request local and state regulatory relief from these impacts.when you think about it, civil engineers are in an excellent position to help minimizeand to manage those impacts to the mutual benefit of both the oil and gas industryand the community.

Environmental Impacts

e environmental impacts associated with hydraulic fracturing seem to revolvearound two primary topics; impacts associated with the drilling and fracturing processitself, and impacts associated with global warming. ere have been numerous com-plaints about air and water quality in the vicinity of drill sites. Fugitive gases andchemical spills near drill sites have the potential for health related concerns. in addi-tion, there have been numerous outcries about the “chemicals” injected into theground during fracturing, about well bore integrity, about the large quantities of waterthat are needed for fracturing, and about the water that’s returned to the surface as aresult of reservoir drainage. All of those issues create opportunities for the responsibleapplication of civil and environmental engineering.

with respect to global warming, the environmental lobby was originally rather positiveabout natural gas as a replacement for coal, but the sheer volume of gas that is beingproduced seems to have created some type of backlash. in general, the environmentallobby is appears to be opposed to all forms of fossil fuel and is deeply worried thatlow cost fossil energy will hinder conservation, reduce the desire for “alternative”sources of energy, and continue to result in global warming. Again, these are topicswhere civil and environmental engineers can provide rational input insofar as rationalinput is part of the equation.


Clearly, and as discussed during last year’sseminar, it is extremely difficult and highlycontroversial to actually accomplish theabove-defined ethical “requirements” forprojects that have significant regional impacts.How does one, for instance, balance all of theproject specific impacts for a large regionalproject with the quality of life impacts for thegeneral public? Or, how does one balancethe short term community impacts of con-struction with the long term public benefitsof the completed project.

it is extremely difficult and highly controver-sial to actually accomplish the above-definedethical “requirements” for projects that havesignificant regional impacts. During last year’sseminar we discussed how does one, forinstance, balance all of the project specificimpacts for a large regional project with thequality of life impacts for the general public?Or, how does one balance the short termcommunity impacts of construction withthe long term public benefits of the completedproject.

ACEC/CO’s Ethics Seminar on Fracking will be another opportunity to explore theethical considerations engineers need beaware of when engaged working on oil andgas projects. e program will be held ontuesday, January 29, 2013 at the DoubletreeHotel DtC from 12 noon – 5 p.m. Furtherdetails can be found at www.acec-co.org or bycontacting Julie Ann Dill, at 303-832-2200;[email protected].


ere is an almost constant stream of information, both pro and con, that is availablein all of the local and national media outlets. Suffice to say that there is no lack of in-formation about both the advantages and disadvantages of the continued use of hy-draulic fracturing here in Colorado. it is also important to note that this write-up isonly a very brief synopsis of this topic and that the seminar will feature speakers thatare equipped to discuss each of these topics in greater detail. in addition the Expertwitness Ethics Committee has created a website with links to recently published ar-ticles relevant to the seminar and that further describe some of the issues discussedabove (LinK.)

ree Closing Items:

As discussed last year, the primary focus of this seminar is not the process of hydraulicfracturing itself but the ethical considerations that must be addressed by engineershelping to plan, design, and construct these projects in a manner that respects boththe potentially negative impacts caused by the projects as compared to the eventualpositive economic impact associated with project completion.

As also occurred last year, ACEC/CO is also pleased to announce that former Con-gressman Bob Beauprez has agreed to serve as our moderator for this seminar. Mr.Beauprez is well known and well respected for his contributions to Colorado.ACEC/CO is pleased to have him help us with our discussion of the myriad ethicalconsiderations associated with the constructed environment.

US 191 Bridge over the Colorado River Bridge, Moab, UTFigg Bridge Engineers, Inc. Engineering Excellence AwardClient: Utah Department of Transportation

M-E Engineers, Inc. met the University of Wyoming’schallenge to design a long-lasting, state of the art facilitythat meets stringent safety standards and minimizesenvironmental impact and energy use. Complexmechanical and automatic temperature controls wererequired to achieve an energy efficient lab building.These controls optimized the HVAC systems energy usethrough intense control logic and programming, andwere verified and calibrated through an elaboratecommissioning process. Mechanical systems andequipment were gathered in a two-story chase that runsdown the middle of the building. This arrangementkeeps all mechanical equipment easily accessible formaintenance without interrupting users.

The US 191 Bridge over the Colorado River is thegateway to the Arches National Park and the Canyonlands region. Figg Bridge Engineers, Inc.’s design featured specialized staining and textures borneof the earth that blended the bridge seamlessly with its surroundings, keeping the landscape as the domi-nant vista. The bridge’s long spans create only oneriver pier, three fewer than the previous bridge that resulted in a main span of 438 feet – Utah’s longest concrete span. Staged construction of the twinbridges kept traffic moving through the corridor,which was important to the tourism-driven economy,and utilized the footprint of the existing bridge to preserve the environment. The Utah Department ofTransportation’s Colorado River Bridge Replacementproject demonstrates that large-scale highway projectscan reach a compromise between the needs of thetransportation system and the needs and desires of thelocal community.

Point Bonita Lighthouse Bridge ReplacementSan Francisco, CAHDR Engineering Engineering Excellence AwardClient: Central Federal Lands Highway Division of FHWA

Denver Department of Human Services Eastside Facility ispart of the Better Denver Bond Program. The projectpresented a challenge for MKK Consulting Engineers tomeet owner’s representative Empire Construction’s requestto have a net-zero ready facility on a limited budget. MKKachieved this goal for the client by designing an innovativesystem that combined a high efficiency energy recovery variable refrigerant flow (VRF) system from Japan with a pioneering application of indirect/direct evaporativelycooled under floor air distribution (UFAD). Throughout the nearly year-long planning and design phases, the building owner, team architect and design team consultantsmade all large scale building decisions through an integrated and collaborative process.

The Point Bonita Lighthouse once guided steamships enroute to California’s gold. More than 150 years later, thelighthouse still operates, doubling as a historic attractionat Golden Gate National Recreational Area. HDRworked closely with Central Federal Lands Highway Division and the National Park Service to create a saferand more accessible experience for those visiting this historic site, which was closed in 2008. The design teamemployed innovative combinations of unique materials tosuccessfully deliver a bridge to withstand the harsh marine setting while creating a replacement structure thatmaintains the look of the existing suspension bridge. Thebridge is thought to be the only tropical hardwood bridgein the world to incorporate a Noxyde coating systemwhich extends the life of the structure. By utilizing the existing bridge deck and lowering it, this walkway servedas a construction platform as well as providing the U.S.Coast Guard with 24/7 access they needed throughout thebridge replacement.

CDOT hired FHU to design a new bridge over AlamedaAvenue on I-25. However, the project faced significantproject complexities: flooding, a highway below theSouth Platte River, contamination from adjacent industrial sites, and a constrained footprint. The challenge was to address these issues in a way that wasmost resourceful, most cost-effective, and most space efficient. The result was an innovative and ground-breaking bridge and wall design that served four functions: support the bridge, retain slopes and contaminated water, prevent flooding, and pump andtreat stormwater. The design was completed within six months, allowing CDOT to attain funding for construction.

Merrick-McLaughlin Whitewater Design Group design involved removing a vertical drop at an existingdiversion dam and designing an environmentally sensitive, multi-channel river system to enable bothfish passage and boat passage. The new state-of-the-art fish passage facility allows native Colorado endan-gered fish to negotiate the diversion dam, promotingthe recovery of these species. The new boat passagechannel provides a safer white water recreational experience for kayakers and rafters. The project resultsin positive social, economic, and sustainable designbenefits. It promotes the recovery of the Colorado native endangered fish; provides a low-hazard boatpassage; and increases boating, kayaking, and touristvisits – which helps the economy in the Delta area.

Cator, Ruma & Associates’ use of the new technology,“Displacement Ventilation” (DV) for the ventilation andair conditioning of buildings provided Aurora PublicSchools’ Vista PEAK Prep school with a proficient, low energy, sustainable system. Relative to conventional HVACsystems, DV provides more comfortable interior condi-tions, facilitates the design of a more pleasant interior architecture, is more energy efficient and environmentallyresponsible, and provides significantly lower life-cyclecost. This project was accepted for Xcel Energy’s EnergyDesign Assistance Program and earned substantial rebatesfor Aurora Public Schools due to the energy efficient design.

When Air Force Academy personnel noticed cracks inone of the Consolidated Education and Training Facility(CETF) columns, URS was called to the site and imme-diately recommended the placement of temporaryshoring at each of the falling courtyard columns, whichincluded new courtyard drains and a wearing slab. Additionally URS’s design used expansion joint bracketsthat employed stainless steel components more akin tobridges than buildings. The brackets were designed tobe compact, modular, and anchored with the post installed anchors, mitigating disturbance to mechanicalsystems and providing the ability to be installed anywhere along the joint.

Zeroing in on Energy Savings, F.E. Warren AFB, WYMerrick & Company Honor AwardClient: 90 CES/SECB, F.E. Warren AFB

Merrick & Company used an innovative, high-tech aerial approach to analyze F.E. Warren’s Air Force Basefacilities to pinpoint heat loss in building roofs and underground high temperature hot water (HTHW) distribution pipe network. Merrick collected scientificmeasurement data by combining various equipment systems into one aircraft including LiDAR, thermal imagery, airborne GPS, and an inertial measurementunit. The thermal signature data was fused with the collected LiDAR point cloud and then draped onto each 3D building model for further analysis. Data fusion algorithms dramatically improved scientific results; fusion of the multiple datasets provided 3D temperature measurements for each building.

Sterling Municipal Airport Rehabilitate Runway 15/33, Sterling, COArmstrong Consultants, Inc. Merit AwardClient: City of Sterling, CO

In response to several wet years that brought recordlake levels and an extreme spill risk, the North DakotaState Water Commission initiated the Devils Lake EastEmergency Outlet project with AECOM in January2011, with the completion date of June 2012. Due tothe cost and wintertime constructibility concerns, theelected alternative was a pump that included a 350 cfspump station with more than 5 miles of 96-inch trans-mission main, a hydraulic control structure, and a terminal structure and water quality filter located at thedischarge. The project team minimized disruption toagricultural activities of the local landowners and theirtenant farmers that were vital to the economy of the area.

The City of Sterling, Colorado is the first western region airport to receive full support, approval andfunding from the Federal Aviation Administration.The FAA Northwest Mountain Region successfully in-corporated rubblization technology in a runway /taxiway rehabilitation project reducing overall construction costs by 9.76%. Only utilized on statehighways and country road reconstructions, rubbliza-tion was recommended by Armstrong. This proved tobe the most suitable application for rehabilitation of the Portland concrete runway andparallel taxiway pavements because it saved time,lowered costs and reduced existing concrete into rub-ble at its current location rather than hauling off-site.
