Slide 1: 

Convening Webinar Collaborative for Sustainable Transportation and Infrastructure Construction July 13, 2010 Jeff Dhont, U.S. EPA You are watching a special annotated version of this webinar where most of the original spoken narrative appears in animated text boxes in a self-executing Powerpoint show. This allows those who missed the webinar to view it’s essential content. Questions and discussion from the original webinar are not included in this version. --------------------------------------------------------------------------------- [Voice Narrative] I’d like to welcome all of you to this Convening Webinar for the Collaborative for Sustainable Transportation and Infrastructure Construction in EPA Region 9, EPA’s Pacific Southwest Region. This effort is based out of our regional Waste Management Division. Our program is non-regulatory and involvement in the collaborative is voluntary. Our focus is to open a creative environment to advance environmental sustainability through collaborative means. While this is a regional program, we have connections to EPA sustainability programs, information, and expertise at the national level. The purpose of the webinar is to give collaborators a vision for the effort: its focus, framework, and ideas for action. Just what do we mean by a collaborative? By sustainable infrastructure? How will it work and what will it work on? The webinar will present an EPA vision so as to have a tangible focus. But EPA’s vision is not set in stone and it can be modified with your input. We welcome the involvement of additional collaborators who share a passion for this work. There is wide latitude for realizing good ideas. I encourage you to view that as an opportunity to engage. [Note for the Annotated Version] Please note that because this presentation is animated, it is not feasible to deconstruct it into a series of static slides. Printing the presentation will, in most instances, result in graphics which appear to overlap each other. To advance through the webinar, it will be necessary for you to click the mouse between slides and sometimes between animations. Please make sure that the prior animation has completed before clicking. Clicking repeatedly or hurriedly will result in lost information.

Slide 2: 

A commissioned community …to collaborate on projects and products to make infrastructure sustainable …and to make sustainable practices mainstream. [Voice Narrative] I will present more details shortly, but this slide briefly depicts how we envision this cooperative effort and its mission from a high level. We envision a membership with a range of creative and expert capacities commissioned to take actions.

Slide 3: 

One-on-One Networking & Materials Development Cohesion and Focal Projects Self-Sustaining Productivity [Voice Narrative] Within the last year, EPA has interacted with all of you in meetings, by phone, in workshops, through projects, and through sharing materials such as this brochure which you have received. [Voice Narrative] This outreach and networking has formed the first phase of our work and it has been highly productive. We have several project efforts started. [Voice Narrative] We are now moving into the phase of convening and bringing cohesion to the collaborative, and advancing focal projects. We have brought together several small project groups already. This webinar is the first time that all collaborators are together in one venue at the same time. [Voice Narrative] Ultimately, EPA cannot sustain sole leadership of the effort. Our long-term goals would be to have collaborators take ownership and sustain the productivity of the effort.

Slide 4: 

What EPA would like to ask of you Creativity Initiative Collaboration and ultimately, Ownership Open Mind [Voice Narrative] As we are striving to find solutions to complex challenges, we’d like to ask of you these four things. Please be willing to take initiative to do something about what you find. This effort won’t work if everyone lies back and waits for someone else. And please seek synergies among collaborators. Otherwise, we all lose a valuable opportunity. A great advantage of a collaborative is that you don’t have to do everything alone – even on your own ideas. There is leverage available – creative, expertise, programmatic, and sometimes even financial.

Slide 5: 

What does “Sustainable” mean? What is the focus? What’s in it for me us? What kind of collaborative? How will it work? What projects, products, as kernels? What directions? What next? [Voice Narrative] Here is what I will covery in the remainder of this presentation. I will return to this lineup and check off topics as we go. These are the things one would expect someone to ask about this kind of effort, and about which we need a common understanding. [Voice Narrative] Let’s start with the first one.

Slide 6: 

[Voice Narrative for subsequent slide] “Sustainable” is the key word in the name of the collaborative, so we should know what we mean by it. This is important, as not everyone may share the same view. We prefer to use a conceptual definition based on lifecycle systems and embodied environmental impacts. These notions are increasingly taking hold as part of a paradigm shift nationwide. Under these notions, our human activities, among them making products or building infrastructure, have a lifecycle from design to end of life. Each of the elements of the lifecycle creates impacts – things we take out of the environment and things we put back in. We can think of a product or infrastructure or activity in a lifecycle as embodying within it the environmental impacts incurred when making, using, and disposing of it. We can then set about the task of systematically reducing that embodiment.

Slide 7: 

A society is sustainable when the embodied impacts of its economic and social activities are minimized optimally throughout their lifecycle system such that the system can healthily provide and persist. System Lifecycle Conceptual Framework for Sustainability [Voice Narrative] A sustainable product or activity must optimally reduce as many of the impacts as practical, not only one. And it must address all the significant elements of the lifecycle, if possible. There is a tendency, especially in marketing, to hold that any narrow benefit in one area, such as greenhouse gas, makes an entire product “green.” But if we leave out key impacts or lifecycle parts, it may actually cause environmental harm, not gain. Or, the real impact may be quite minimal. We are looking for sustainable infrastructure here. Sustainability, then, for our purposes, is about optimally and systematically reducing the embodied impacts of our infrastructure.

Slide 8: 

What does “Sustainable” mean? What is the focus? What’s in it for me us? What kind of collaborative? How will it work? What projects, products, as kernels? What directions? What next? [Voice Narrative] Sustainability is wide and cannot be covered in one effort. So I will discuss what EPA envisions as the focus for this effort and how it might grow in the future.

Slide 9: 

[Voice Narrative for subsequent slide] Our effort falls within the context of at least six broad and overlapping areas in which humans interact with their environment. Having this big picture in mind is very useful even though we won’t be focusing on all of it. The focus for our effort will be on the built environment –how we build things such as highways and civil infrastructure, particularly with regard to materials. Many thigns we build have a high footprint of greenhouse gases, resources, water, and energy. Because so much of our infrastructure is linked to our communities, we will also place an intentional focus on how we live and build communities. We are seeking to make communities a locus of change and to assit them in adopting more sustainable practices, codes, specifications and products.

Slide 11: 

Holistic Collaborative Focus Stormwater Control Land use and smart growth Green supply chains Byproduct synergy and local reuse Building design Energy and water efficiency Renewable Energy for Infrastructure Reduced petroleum demand Reduced toxic content Reuse of Materials Initial Focus Involvement by Connection [Voice Narrative] Our initial focus will be on reusing materials to reduce the impact footprint. But, because sustainability is holistic, we will clearly encounter and indorporate sustainability elements in many other areas, and likely eventually expand or merge projects into those areas –for example, those shown here.

Slide 12: 

[Voice Narrative for subsequent slide] An EPA program funding much of our program focuses on increasing the beneficial reuse of six classes of materials from industry and demolition of buildings and roads. You can see that huge volumes of these materials are produced each year. A not insignificant percentage finds its way to reuse markets. But a tremendous volume still ends up in landfills. They carry a very high footprint of embodied impacts. Acquiring and using them requires mining, transportation, large amounts of water, discharge of greenhouse gases, destruction of habitat, and depletion of resources. So their reuse in construction of infrastructure can make a significant reduction in its environmental footprint. We make use of environmental impacts already incurred rather than incurring new impacts.

Slide 13: 

Six Classes of Industrial & Debris Reusable Materials

Slide 14: 

[Voice Narrative for subsequent slide] This figure illustrates the most common uses of reused high-volume industrial materials and debris. You can see most lie in infrastructure applications. These materials are primarily composed of earthen minerals and are effective at filling, providing structure, holding materials together, or providing drainage, friction, and vibration control – properties necessary when building “stuff”.   You have all received aTopical as part of our initial documents a few months ago – it is a matrix of these materials, their functional reuses, and applications in infrastructure. The topical goes into more detail about these uses. If you have comments or additions to this document or any other of the topicals, please let me know.

Slide 15: 

Common Reuses of H-V Industrial Materials, C&D, Tires

Slide 16: 

[Voice Narrative for subsequent slide] This example is useful. Most of you, but not all, are well aware of sustainability aspects related to concrete. Because concrete is used in such huge quantities in construction of infrastructure and can have a very large environmental footprint, I’ll use it here as a brief example of how it can be made more sustainable in light of the materials that go into it. We could tell a similar kind of story for asphalt, structural agggregate, or buildings, for instance.

Slide 17: 

Carbon locked in mineral form is released as CO2 Limestone CaCO3 Calcium Oxides + CO2 Fuels + O2 CO2 + H2O Thermal Oxidation Making a ton of Portland Cement Releases a Ton of CO2 Stack [Voice Narrative] The traditional binder in concrete is Portland cement. This slide shows just part of the process by which Portland cement is made. Making one ton of Portland releases about 1 ton of carbon dioxide greenhouse gas. About half of this is due to combustion of fuels to heat the kiln. The other half is released when carbon originally locked in calcium carbonate is freed as carbon dioxide, leaving behind the key calcium oxides in cement. In addition to greenhouse gas, large amounts of virgin resources are needed as raw materials. The replacement of Portland cement with alternate materials in concrete has therefore become a focus for making concrete greener.

Slide 18: 

Portland Cement At the Concrete Plant: More Sustainable Materials SCM: Coal Fly Ash SCM: Granulated Blast Furnace Slag “Ternary Blend” Conventional Portland Cement Aggregate made from recycled materials Ternary Blend Binder [Voice Narrative] This simplified cartoon shows how a batch plant might reduce the footprint of concrete. Some of the Portland cement is replaced with reused industrial materials that have cementitious properties. In this example, a “ternary blend” binder is mixed using Portland cement, coal fly ash, and ground granulated blast furnace slag. In principle, the greater the amount of Portland cement replaced, the lower the carbon footprint of the resulting concrete. [Voice Narrative] Another opportunity for reducing the footprint of concrete is using recycled aggregates rather than virgin aggregates. Because the environmental impacts of mining, transporting and making recycled aggregates have already been incurred, we avoid incurring those costs again if we reuse them.

Slide 19: 

[Voice Narrative for subsequent slide] Now, why can’t we just immediately adopt these techniques – such as substitute out all cement or use only recycled aggregates? From the left of this diagram one can see these techniques and even several others that can make concrete more sustainable. Some of these can apply to asphalt as well. However, these must be balanced against the need for concrete or asphalt to perform as needed for any particular application. For example, the right side of the figure is a partial list of concrete properties that the concrete engineer must be concerned with – these are, in fact, what he is paid to provide. The materials used, including SCMs and recycled aggregates, can affect most of these – depending on the application and type of concrete needed. There is no single sustainable concrete mix that will work for all applications. An economically viable sustainable product must be capable of performing to expectation and provide reasonable cost-effectiveness, as well as environmental sustainability. A key question, though, is have we been innovative enough to overcome the engineering limitations rather than just presuming they are insurmountable? Smart, progressive and forward-looking industries are doing just that.

Slide 20: 

Replace Portland Cement with other cementitious materials Use recycled, reusable or innovative aggregates Use less material overall and reduce overdesign Use less virgin-mined material Use less water- and energy-intensive processes for mining Reuse “returned concrete” from construction site Use pervious concrete Make concrete more durable (future benefit) Green the supply chain and supply networks Slump – workability during pour Water demand Cement and aggregate particle size Early strength and strength/cure curve Compressive / tensile strength at key times Hardness and smoothness Long-term durability Shrinkage Freeze/thaw cracking resistance Resistance to sulfate attack Resistance to chloride intrusion Resistance to Alkali Silica Reaction (ASR) Resistance to salt scaling Matching Green Concrete Opportunities….To Performance Needs

Slide 21: 

[Voice Narrative for subsequent slide] To finish this off, let’s quickly look at where all our materials can be used within the anatomy of a road, or roadway or streetscape infrastructure. A roadbed is usually constructed of a stacked series of increasingly engineered courses, starting with graded and compacted native soil sub base, then UNencapsulated aggregates, followed by low-strength cement-stabilized road base, and finally, the high-performance pavement course, which sustains the day-to-day high stresses of traffic and weathering. Recycled materials can be used in most applications requiring soil stabilization, support structures, or enhanced drainage. This includes walls and embankments and the fill behind them, bridges and aerial guideways, and such, …as well as urban curbs, sidewalks, streetscapes, parking lots, water infrastructure and of course, importantly, buildings.

Mark Maloney, DPW, Shoreview, MN Pervious Pavement Surfaces – Runoff Control, Safety, Friction, Sound StormWater Low Impact Development for Infrastructure Pervious Concrete Porous Open-Graded Asphalt (RAC-O) Mark Maloney, DPW, Shoreview, MN [Voice Narrative] Infrastructure materials are intimately tied to stormwater management as well. Pervious concrete and asphalt allow water to drain away from roadway and parking lot surfaces into the ground or controlled basins, and can enhance friction and vehicle safety. You can see in the pictures conventional and pervious products side-by-side during a rainstorm –note the difference in the wet surface.

Slide 30: 

Runoff Control, Bioinflitration, Biopurification, Water Harvesting StormWater Low Impact Development for Infrastructure Bio-swale Rain Gardens, Bio-infiltration Basins and Ponds Rainwater Harvesting [Voice Narrative] Bioswales and infiltration ponds allow water to percolate into the ground rather than migrate as runoff to distant water bodies. These structures may filter the water in addition to creating green open spaces and habitat which enhance livability and community design.

Slide 31: 

What does “Sustainable” mean? What is the focus? What’s in it for me us? What kind of collaborative? How will it work? What projects, products, as kernels? What directions? What next? [Voice Narrative] A common question when participating in a group is, “what is in it for me?” So that is next. I prefer to talk about what is in it for us, collectively, because we can all gain where one gains here.

Slide 32: 

No one entity has the knowledge and capacity to bring about sustainability by itself Old Economy New Green Economy The system of interaction of humans and their environment is complex. Less virgin mining Less resource depletion Less GHG emissions Less water use Less water pollution Renewable resources Fewer toxins Less contaminant migration Ecosystem stability Regenerative land use Long-Term Business Stability / Profit OPPORTUNITY Green Market Niche New & efficient markets Lower costs Recognition Compliance YOURNICHE More durable and reliable infrastructure Better products Smarter community design More stability Lower costs Community recognition Advancement of sustainable thinking and lifestyle ENVIRONMENTAL ECONOMIC SOCIAL [Voice Narrative] An impetus for creating this collaborative comes from the realization that no one entity can bring about sustainability in a complex world. It will take combined involvement from entities throughout the system. So we need to integrate individual capacities –knowledge, expertise, resources, and ideas. [Voice Narrative] The environment can benefit from our efforts in a number of ways that we have already talked about. If the actions taken are designed to optimally reduce embodied impacts, then the environment can healthily persist and continue to provide for the human activities on which business and the public depend. [Voice Narrative] The collaborative can be viewed as an opportunity for smart innovators to open doors to a green niche in the new green economy. The collaborative and EPA’s involvement can potentially provide greater public recognition and profile to those who make strides to build sustainably. In many cases, construction using sustainable materials and methods can be less expensive than traditional construction especially if whole project lifecycle analyses are performed during design. [Voice Narrative] Finally, the public can benefit by enjoying better products, more durable products, and especially, but learning the very principles of sustainability through what they see being built around them.

Slide 33: 

What does “Sustainable” mean? What is the focus? What’s in it for me us? What kind of collaborative? How will it work? What projects, products, as kernels? What directions? What next? [Voice Narrative] We are aware that while talking, discussion, sharing and education have important roles, too many partnership efforts stop there. Everybody listens and goes home with their notes but nothing happens. We don’t just want to talk or do random “green stuff.” We’d like to extend this effort beyond what has often been described as a simple “partnership.”

Slide 34: 

[Voice Narrative for subsequent slide] As a model we like the idea adapted from concepts put forth by Peter Senge and others. First, for persons and organizations to collaborate, they must understand the lifecycle system, how the players interrelate, and what their impact, experience and capacity is. Collaborators must then be able to reach across their typical roles and boundaries. For instance, corporations may usually set off against regulators. Asphalt makers and concrete makers may see themselves as competitors. Landfill operators and recycling processors as adversaries. These roles need to be set aside at least temporarily. It takes some effort to do this, but the rewards can be great. This sets the stage for looking for synergies among resources, crafting win-win solutions, promoting awareness of the whole system, and finding options that didn’t exist for any one party alone. In turn a vision will emerge of a desired future, wherein sustainable practices are mainstream and conventional, the environment is not depleted, and businesses continue to flourish for the greater social good. Ultimately there must be action, not merely talk, and so our collaborative seeks to build in action from the start – and use action as a kernel of focus for more action. This is what we have started already with the several projects moving.

Slide 36: 

AB&I Foundry [Voice Narrative] These are the twenty nine entities presently engaged in CSTIC, and we anticipate more. The mix of parties among private, public, academic, industry, public interest, etc. may not yet be ideal – we can adjust this on the fly as new members join. [Voice Narrative] You have received our Topical #2 in which these entities and something about them are listed –though additional parties have joined since Topical #2 was issued. We will be asking members to provide us with more information so as to update Topical #2.

Slide 37: 

What does “Sustainable” mean? What is the initial focus? What’s in it for me us? What kind of collaborative? How will it work? What projects, products, as kernels? What directions? What next? [Voice Narrative] We see work in the collaborative taking place on two different levels: first, on the level of the whole group; and second, on the level of individual projects. Our view is to execute a vibrant set of projects that receive creative input and growth and that get going quickly, leading to more actions.

Slide 38: 

[Voice Narrative for subsequent slide] At the level of the whole collaborative, we now need to establish a coordinating leadership. The group as a whole would identify and examine barriers to sustainable infrastructure. Understanding barriers - and why they are in the way is necessary to removing them. EPA has already identified a set of barriers based on input from you during our first networking stage. The most vibrant element would be what we can call the “Idea Mill.” This would be the venue into which to bring creative ideas for projects and actions. Ideas would incubate, be refined, made realistic, spun off, gather new participants, and garner resources. Individual projects would then be undertaken by project teams, which could be fluid in terms of membership. We have several projects queued up and these will be briefly described in a moment. Likewise, there would be teams for products that result in a database, document, tool, etc. rather than a field result, program, etc. Finally, many collaborators and outside parties have educational materials and information they’d like to share with collaborators and CSTIC can serve as a forum to hold these.

Slide 39: 

Leadership & Framework Project Teams Product Teams Educational Webinar/ Workshops All Collaborators

Slide 40: 

Project Nuclei [Voice Narrative] We propose to use projects right off as nuclei – to focus the group right out of the gate toward actions. Each collaborator can be involved in the project team for as many projects as makes sense and for which value is added.

Slide 41: 

What are the Barriers? If you had full collaboration of CSTIC members, what project, program, product, approach could remove these? [Voice Narrative] The barriers you have previously identified to us fall into the four categories you see here. There are too many barriers here to go over one at a time in this presentation, but they are described in detail in EPA’s Topical 4 which you have previously been provided. [Take a look at the barriers before advancing to the discussion on the next slide.]

Slide 42: 

[Voice Narrative for PREVIOUS slide] Actions we undertake are designed to address these barriers. As you can see, solutions to some of these may be simpler, as in providing education, or running a necessary field test. Others, such as building market infrastructure, overcoming price disincentives, and changing specifications that are well accepted and proven, are more difficult and may require a wider range of expertise and cooperation. One barrier that consistently stands out is the need to update specifications. As is the case with concrete just discussed, construction products can be complex and there is liability on the part of specifier and contractor for performance of the product. Materials decisions must be considered in context with performance needs. At the same time, a great number of projects are completed using old standard specifications just because “they’ve always worked” – when data are well-established that more sustainable, well-performing, and even cheaper options are available. We need to be sensitive to both sides of this issue, and convening many of the players to hash it out is a great way to do that. Another key barrier is market development, particularly of intermediate market parties - processors, for instance. Often, having intermediate market outlets, including sufficient and reliable quality and quantity of materials within proximity to a project can make or break whether reuse occurs at all. The challenge is to find good ideas to enhance investments and capital in such infrastructure.

Slide 43: 

What does “Sustainable” mean? What is the focus? What’s in it for me us? What kind of collaborative? How will it work? What projects, products, as kernels? What directions? What next? [Voice Narrative] So, let’s talk with more specifics about what projects we are starting as kernels of activity for the collaborative to focus on early.

Slide 44: 

Project Types Existing Projects Ready to Move Forward Project Concepts with Promise New Projects to be Proposed Focal Projects [Voice Narrative] This section divides existing projects into basic types, and gives a description of projects that are already underway or are under consideration. Some of these ideas are more established, while others are more conceptual as of this webinar. We welcome collaborators joining project teams especially if they have capacities that could enhance the projects. Existing projects may give you ideas for additional projects !! So make suggestions! !

Slide 45: 

[Voice Narrative for next slide] Project type A involves using a local venue for demonstrating many different technologies, materials, and practices within a single and high profile project. An example is a public square, a green street or streetscape, or even a private development that is being built green to conform to civic plans. While more complex to pull off than other ideas, this type of project can be rewarding because results are highly visible and reach a large number of people, more collaborators can be involved, many sustainable practices can be demonstrated at the same time, and there is room for market development and recognition of both cities and vendors. We foresee CSTIC becoming actively involved in assisting designers with vision and technical expertise – providing “green teams,” as it were.

Slide 46: 

High Profile Multi-Component Public Streetscape, Center, Development, Transit High visibility and lifestyle effect. High public education potential Opportunity for recognition for local governments and green market vendors Streets, sidewalks, flatwork, walkways, drainages, parking lots, water conveyances, foundations, meeting places, parks, buildings, residences, landscaping, transit Use of “GREEN TEAMS” from CSTIC to engage with design Potential to incorporate a “GREEN CHALLENGE”

Slide 47: 

San Diego Centre City Development Corporation non-profit redevelopment through City Remaking of designated streets as green streets: streetscapes, streets, existing and new buildings Model for sustainable construction and specifications Build into county general and sustainability plan Possible EPA Partnership Agreement Green Streetscapes [Voice Narrative] One promising Type A project is the Green Streets program of the San Diego Centre City Development Corporation. CCDC is a non-profit corporation established through the City of San Diego to advance sustainability in the downtown area. Part of CCDC project is to take a handful of designated streets and convert them to “green streets.” They are looking to adopt new construction specifications that can be models for and be built into the Sustainability Plan for the County.

Slide 48: 

Existing Elements prior to CSTIC Wider sidewalks and walkability Access to new parks Incentives for building energy retrofits Vegetation and shading High density housing to reduce traffic Energy-efficient street lighting Bicycle Lanes Zero-irrigation landscaping Open space [Voice Narrative] This figures shows where three of the green streets in the CCDC project would be located in relation to the downtown San Diego area. There are existing streets and buildings, and potentially new buildings and parks. Some of the elements of the project currently planned, prior to CSTIC involvement, are shown. CSTIC could serve a strong role in lowering the footprint of construction of the new streets and streetscapes. I will zoom in on two of the streets and show an example of how CSTIC could assist in making the green streetscapes more sustainable.

Slide 49: 

DownTown Cedar Broadway Front Union Kettner [Voice Narrative] Here are views of two of the streets that would be part of the project. You can see there is a mix of urban residential, business, parks, and schools.

Slide 50: 

[Voice Narrative for next slide] This is a conceptual depiction of how materials sustainability in particular could be incorporated into this project with the assistance of CSTIC. This is just a vision at this point. As an example, the Union Street reach could be divided into three parts, each demonstrating different technology and materials. I am depicting concrete, asphalt and rubber sections here. Differing technical project team members could work on each segment if appropriate. For existing streets, sustainable demolition technologies could also be employed. Sidewalks could also be divided into zones to demonstrate differing types of concrete, or just all utilize one ultra-green type. Finally, we certainly would want to take advantage of the tremendous potential for public education afforded by such a project. So, for instance, something like the sign you see here could be used.

[Voice Narrative for next slide] Another Type A Project-- EPA is exploring partnership agreements with the California High Speed Rail Authority to assist in greening the California High Speed Rail. This is a planned 42 billion dollar project with more than 1700 miles of trackway, 120 tunnels, and hundreds of aerial guideways between the San Francisco, Sacramento, and Los Angeles areas. Trains will move at speeds up to 225 miles per hour. Over 150,000 jobs will be associated with its construction. The CA High Speed Rail Authority has expressed a strong interest in becoming a model for a green high speed rail system for the United States and for the world. The greatest anticipated environmental footprint from construction of the project is the embodied resources, energy, and carbon associated with the volume of concrete that will be required. The rail ties must be concrete, and there will be numerous stabilization, grade control and tunnel structures, in addition to stations. Tire-derived aggregate may be appropriate for stabilization and vibration management. The rail will pass through many cities and towns in the California Central Valley, as well as through urban areas. Smart growth, stormwater management, ecosystem impacts, sustainable city planning and use of recyclable materials are all pertinent. While HSRA, and not CSTIC, will design the system, we believe that CSTIC can provide valuable input to the design team.

Slide 55: 

Not yet explored Transbay Joint Powers Authority $4 billion cost [Voice Narrative] At one terminus of the high speed rail, the new San Francisco Transbay Terminal will be a connection hub among several regional and local transit systems. The system is being constructed by the Transbay Joint Powers Authority, a collaborative of transit agencies and governments. The anticipated cost of construction is $4 billion. I stress that we have not yet approached the Joint Powers Authority nor know whether CSTIC can play a role. However, this kind of infrastructure construction also could be ideal.

Slide 56: 

Request for Project from City of San Jose, which has expressed interest in a green project Other Cities not yet approached: Berkeley, Phoenix, Los Angeles, Sacramento, Chula Vista, or any others expressing interest [Voice Narrative] Finally, the City of San Jose has expressed an interest in hosting sustainability projects with the collaborative, and we have asked them for specific ideas for such projects. We may ask for project ideas from other cities such as the ones listed here. We have not yet approached these.

Slide 57: 

[Voice Narrative for next slide] A Type B project is a single construction venue sponsored by a public entity or private development, attended by observers and knowledgeable experts, to demonstrate a single technology, material, or practice and facilitate its adoption. It “showcases” a technology and has a significant public profile. Alternately, such projects may be simpler demonstration tests to gather data on the performance, reliability, or cost of single sustainable practices or materials. Here are some possible infrastructure applications -- for asphalt…for concrete (note the many different types of civil infrastructure especially for stormwater) ...and these other kinds of techniques and applications. Full-depth reclamation is a technology whereby an existing roadway is excavated, ground, and reused immediately as aggregate in a new roadway. It has closely-related cousin, cold in-place recycling.

Slide 58: 

Single Component Showcase or Demonstration Test A convergence of observers and knowledgeable experts at a single construction venue to demonstrate a single technology or practice and facilitate its adoption. AND/OR Conducting tests to evaluate issues, performance, procedures, or cost of products differing from typical specification.

FHWA Technology Showcase Demonstrations Existing FHWA Program Often in Local Jurisdictions San Jose: Environmental Center Parking Lot and Roadway San Jose, San Diego, San Francisco and Chula Vista: Shingles in Asphalt demonstrations in conjunction with private recyclers/asphalt companies NRMCA , RMC-REF and ACI: Green concrete challenge to industry open to designing an uber-green concrete for a local project [Voice Narrative] We can team with an existing program that the Federal Highways Administration has for technology showcases. A technical team from FHWA often collaborates with a specifier and vendor on a project already set to be peformed.

Slide 60: 

Collaborators American Concrete Institute and Central Concrete will coordinate with EPA and CSTIC to run a test of the performance of concrete made with significantly higher returned concrete content than is currently common. Up to 7% of batched concrete comes back in the truck unused. Specifications limit the amount of returned concrete that can be remixed. Some can be hardened, crushed and used as aggregate, but performance needs limit this. Most returned concrete is wasted, along with its embodied CO2, energy, water, and resources. [Voice Narrative] This project works with what is known as “return concrete.” Up to 7% of concrete may come back from construction jobs still in the truck. Regulations often significantly limit the amount of return concrete that can be rebatched and sent back out. While some returned concrete can be allowed to harden and then be crushed for use as aggregate, much of it is wasted. This is a very significant loss of the embodied resources, energy, water, and carbon associated with concrete. The American Concrete Institute and Central Concrete in California has proposed to run a controlled demonstration using returned concrete. In this proposal, ACI and Central will create a simulated return concrete and then “rebatch it” in varying percentages into fresh concrete. Its properties, cure rates, and performance will be measured. The results will be documented with the intent of assisting decisions about appropriate applications of –and specifications for –returned concrete.

Slide 61: 

Collaborators Central Concrete, AB&I Foundry, and Pacific Steel are examining placing foundry sand as a low-volume aggregate into low-strength concrete materials, such as flowable fill. This practice is accepted and proven in the east. Market issues and solutions being evaluated. Could be expanded to additional foundries and batch plants. [Voice Narrative] Foundry casting sand is used in molds for metal castings up to a hundred times before it loses the physical properties that allow for a quality casting. However, the sand retains properties suitable for construction purposes. Collaborators Central Concrete, AB&I Foundry and Pacific Steel are examining batch mixing foundry sand as a minor component into low-strength concrete materials, such as flowable fill as seen here. This practice is fairly well established in the eastern U.S. The collaborators are looking at the market viability of this approach. Other foundries and batch plants may have an interest in expanding the effort.

Slide 62: 

A national team of experts in the field of infrastructure sustainable materials makes a review of the set of state, regional or local construction specifications and make recommendations for improving sustainability without losing performance. Expert Specification Sustainability Review [Voice Narrative] As a great many projects follow standard specifications, Project Type C has tremendous potential. It would create a pilot program where an expert team with the latest national knowledge would, based on knowledge of the latest state-of-the-art information, review the specifications of state or local agencies and make recommendations for changes to increase sustainability while maintaining performance. The recommendations would be documented and assistance would be given to those responsible for the specifications. This could be performed for CalTrans or ADOT specifications, or the GreenBook specifications of the American Public Works Association. A project similar to this was already done with the FHWA and the State of Colorado, with some assistance from EPA.

Slide 63: 

A Green Infrastructure Challenge A competition to develop the most sustainable product while still meeting cost and performance requirements set in advance. Technical Team 1 Technical Team 2 Technical Team 3 This could be inserted as a component of most of the other field project ideas.

CSTIC Potential Products

Slide 65: 

These were only a start… [Voice Narrative] We must stress again that these ideas are only a start, and that your ideas are needed to refine them but also to suggest new projects. Please consider your experience with the barriers, your expertise, and suggest something to make a difference. You needn’t flesh out a project idea completely to bring it to the collaborative.

Slide 66: 

What does “Sustainable” mean? What is the focus? What’s in it for me us? What kind of collaborative? How will it work? What projects, products, as kernels? What directions? What next? [Voice Narrative] Now to moving forward. Here are five directions, or areas, that we think we should pursue simultaneously. EPA is providing an opportunity, though members must engage directly otherwise EPA will not have the resources necessary to maintain the effort in all those areas. On the next few slides, you will see that we plan to send a poll to you to get input which we will digest and can follow up in subsequent interactive discussions. We want any suggestions about how to make these proposed directions and next steps better.

Slide 67: 

Direction 1: Develop Collaborative How would you like to see the leadership set up within the larger collaborative? Should we formulate a basic framework document? What do we DO to better become acquainted with each other’s capacities and ideas? Who else should be in the collaborative, in your opinion? ASK YOURSELF

Slide 68: 

Direction 2: Everyone Sees the Barriers Clearly What are the barriers to making sustainable infrastructure the normal way of doing business? How do we ensure we have a common understanding of the barriers? Which barriers are most important? What can we do to lower the barriers? Which collaborators could you work with to do it, given your capacities and experience? Keep our eyes on what is in the way as a pointer to what to do. ASK YOURSELF

Slide 69: 

Direction 3: Action Right Away Join and Advance the Kernel Projects The project and product ideas already on the table should proceed and develop. This will focus the group and spur its development. Which projects discussed would have the most potential to make significant change? Which projects discussed above do YOU want to participate in on the project team? How would you refine or add to these projects? ASK YOURSELF

Slide 70: 

Direction 4: Crank up the Idea Mill Ideas lead to action. Action leads to ideas. Push both directions at once. Project and product ideas come to the full collaborative “Idea Mill” as an incubator for: Brainstorming Fleshing out and refinement Adding, expanding, combining or growing ideas Adding new participants and capacities Realism Developing funding options What other projects would you propose that the collaborative explore? How would you set up the idea mill? ASK YOURSELF

Slide 71: 

Direction 5: Start Sharing Information Do you have a presentation you would like to give and record to a library as a CSTIC Webinar? Share information about a technology, product, process, procedure, material, to make infrastructure more sustainable. What Webinars would you most like to see for your own education? What ideas and opportunities could you offer for the collaborative Web site? ASK YOURSELF

Slide 72: 

Next Steps Input and Discussion NOW as soon as possible: Leadership and Idea Mill Ideas? Who else should join the collaborative? What do you think of the existing projects? Which project teams you would like to join? What are your Ideas for new projects? Critical barriers you want to inject for discussion? What educational Webinars do you propose to offer or attend? EPA Poll, Next Webinars to Address the Above Project Team Execution / Development
