Subject:          2010 OSU Civil Engineering Capstone Project

Project:          Troutdale Reynolds Industrial Park - Phase II (TRIP-II)


The Port of Portland is a public agency serving the cargo and passenger transportation needs of Oregon
and SW Washington by constructing, operating and maintaining transportation infrastructure and
engaging in land development that enhances business activity and supports employment in the region.
Its mission statement is as follows: “The mission of the Port of Portland is to enhance the region's
economy and quality of life by providing efficient cargo and air passenger access to national and global

The Port has historically been and continues to be a primary land developer in the tri-county area of the
Portland metro region, developing large tracts of property to support transportation and industrial
needs. Such property development has included the Portland International Airport, Rivergate Industrial
Park, Portland International Center and most recently the Troutdale Reynolds Industrial Park (TRIP).
These properties have included developing land for long term lease as well as site development for land

The TRIP project is a property acquired by the Port in 2006 and includes approximately 700 acres of
land, part of which was previously occupied by the Reynolds Metals aluminum smelting plant. The site
was designated a superfund site by the EPA in the 1990’s due to long term contamination of soils and
ground water resulting from the manufacturing processes of the aluminum plant. A superfund
mitigation project has been in operation for several years and will continue to operate until the site is
determined to be below designated levels of contaminants. The principal contaminant is fluoride.

The Port developed phase I of the TRIP site in 2008/2009. The scope of phase I included planning, the
reconstruction of existing streets as well as constructing a new street, wetland enhancement, site
development, landscaping, utilities and fill material management. The site remains constrained by the
superfund designation whereby soils removed from the site must go to a hazardous waste landfill.
Contaminated soils can be reused or disbursed on the existing site. The first of three lots has been sold
2010 OSU – CE Capstone Project Description                                                Page 2 of 6

and developed by FedEx with the construction of a 400,000 SF distribution center. The remaining two
lots of phase I are currently being marketed for sale.


The Port is initiating a study of tract D of the TRIP site which is considered phase II of the development
project. However, the Capstone project will be limited to the area now designated lots 4 through 6
totaling approximately 82 acres. All three lots have some existing wetlands as well as involvement in the
groundwater restricted zone as determined under the superfund listing. Lot 6 is further encumbered by
the presence of a high pressure natural gas transmission line.

Refer to the Phase II RFP for additional detail and site drawings for the property. Specifically, page 33 is
the Constraints Map which shows wetland and groundwater restricted zone boundaries.

The scope of the OSU Civil Engineering Professional Practice Course (CE 418) and Capstone Design
Project (CE 419) will be to develop planning and design documents for the lot 4 through 6 portion of
Tract D as described above. The Port has issued a request for proposals (RFP) for consultant services to
develop a planning study for the site. The RFP is included in the packet of information provided to OSU.
This project will be an interesting and multifaceted exercise for a multidisciplinary engineering team and
give them an opportunity to evaluate their solutions against the progress made by the selected
consultant team. The teams will be able to use their engineering education to develop their own plan
for the site and execute design elements.

Essential elements of this project will include the following:

Winter Term – Site and utility planning

    1. Produce Subdivision Plot for the study area.
       The subdivision plot should be as the individual teams define it. They should list assumptions
       and potential uses as they plan this raw piece of land. They could use the FTP documentation to
       the extent that it would provide a guide.
    2. Develop Survey Plan for the specific proposed site development for each lot as well as street
       The survey plan should be built around the survey data that is provided in the FTP
    3. Develop general Drainage Plan for Phase II including evaluation of and connection to existing
       conveyance infrastructure.
       Drainage should be based on some quantity of impervious surface as the teams develop their
       site and subdivision plans. The capacity of the existing system would be in the FTP
       documentation. The teams should be able to calculate the capacity of the existing system and
2010 OSU – CE Capstone Project Description                                               Page 3 of 6

          determine what they are adding and the ability of the existing system to handle the additional
    4.    Evaluate Salmon Ck. and its capacity to accommodate additional runoff using storm water
          modeling software or manual calculation.
    5.    Analyze Sanitary Sewer Infrastructure and the possible need for a sewage lift station.
          The plan will establish the ultimate potential sanitary needs. For the purpose of the exercise,
          teams will need to account for the needs based on the building construction and some
          assumptions of the potential type of development on the other properties. They will need to
          state their assumptions and design their capacity requirements around those assumptions.
    6.    Define constraints related to the presence of contaminated soil and how work will be done in
          the area.
          The FTP documentation should provide some guidance on the status and impact of the
          contaminated soils. There is a question that we will be pursuing concerning the constraints
          imposed on the property if the contaminated soils remain in place. There is discussion of
          placing a 1’ sand cap over the contaminated soil then building on top of it, but this doesn’t
          address the obvious question regarding digging through the cap to construct underground
          utilities or to install piles and what this may do to soil layers below the contaminated layer and
          the potential vertical transmission of contaminants. This is an item that the teams should
          consider and indicate their assumptions, analysis, findings, and recommendations in their
    7.    Develop a Mitigation Plan and the creation of compensatory wetlands west of Sundial Road to
          allow for development.
          The teams should approach wetlands on the basis that existing wetlands that are impacted by
          development need to be replaced elsewhere on site. The Port needed to expand Company Lake
          on the water side of the levy to address the loss of wetlands due to FedEx. We did expand the
          Company Lake wetland with additional capacity to accommodate phase II.
    8.    Produce a preliminary layout (preliminary horizontal alignment and draft standard cross
          sections) extension of Swigert Wy. to Graham Rd.
          The FTP documentation will provide guidance on the construction detail for Swigert and by
          extension Graham. They can design based on the sections, width and alignment indicated in the
          Phase I documentation. The teams should match the design issues/elements established by the
          Swigert design.
    9.    Determine improvements to Graham Rd. to handle traffic load consistent with the design
          basis of Swigert Rd. and Sundial Rd.
          Comply with Port and City of Troutdale design standards for industrial parks (e.g. curbs,
          sidewalks, street lights, landscaping, etc.). Provide public and private utilities requirements in
          the analysis. The design of Graham Rd. can be based on the Swigert section, design load, layout,
          alignment, etc.
    10.   Review available Traffic Study to determine whether it includes evaluation of the intersection
          of Graham Rd. and Sundial Rd. and what, if anything, need to be included in any revision to
          assess if a traffic signal is required.
          The teams should review the study to establish the basis for the project.

    11. Consider alternatives for sustainable design. Such alternatives will need to have analysis
        performed to justify the expenditure on a cost/benefit basis.
        The term “sustainable” is, to date, not well defined by the engineering community. There are
        strategies to achieve some measure of what people may define sustainable such as on-site
        power generation, on-site processing of storm water using bio-swales, preservation of natural
        habitat, reuse of black water from sanitary systems, etc. The teams should look objectively at
        the potential strategies and make some determination of their viability and the return on the
        investment. For example, solar PV is all the rage, but is it viable from a cost perspective and
        whether it achieves reasonable economic and environmental return. This is left to the creativity
        of each team. Be prepared to defend your recommendations and back them up with objective
    12. Site a 100,000 SF light manufacturing building with 20,000 SF of class B office space, including
        surface parking, on the west third of lot 6.
        Teams should do a layout on the site including access, street visibility, drainage, etc. for the
        building footprint. The building will incorporate tilt-up concrete construction, long span roof
        construction with 30’ high manufacturing space and include a 10 ton bridge crane, and possible
        energy generation and sustainability strategies. The building will be designed to meet LEED
        Silver rating. Runoff from the parking surface will be directed either to water quality facilities or
        the parking pavement will be porous construction.
    13. Produce Development Concept that will incorporate preservation of natural wetlands and
        habitat to give the site a feeling consistent with the natural area surrounding the site. Access
        to the pedestrian bike path on the top of the levy and to the Sandy River on the opposite side
        should be considered.
        This is left to the creativity of the teams. This should consider aesthetics, maintenance access
        and other issue in the overall planning and design a development that would be pleasant and
        efficient to work in.
    14. Evaluate the impact of either relocating the high pressure natural gas pipeline to better
        accommodate development or leaving it in place and the resulting encumbrance to
        developing that land it passes through.
        Relocating the nat. gas pipeline will need to be programmed with some costs. It is suggested
        that the teams use MEANS (or some other method) to make a reasonable assessment of the
        construction costs. If teams determine that the relocation costs would be prohibitive, then they
        need to plan based on its remaining developable land in place. They will then need to
        determine what accommodations need to be made to build around it.
    15. Develop Permitting Plan to determine time impact on overall project delivery.
        The teams should identify the permits they will need for the project. The FTP documentation
        should give some guidance in this matter or it may require the teams to research with the city
        what their requirements will be. Go primarily with what is in the FTP. DO NOT call the City of
        Troutdale asking questions about the TRIP site. It would confuse the City, since they may not
        know that the question is based on a hypothetical project and not the actual project that the
        Port is working on. Direct all questions through the Capstone Project contacts.

    16. Produce a preliminary Project Design Schedule showing milestones and critical path.
        Project design schedule should be based on the overall delivery of a set of design documents
        and permitting documents. It should include intermediate milestones such as scope
        development, 30%-60%-90%-100% design levels, client and agent reviews, corrections,
        approvals, design completion, etc. They should be able to provide some judgment and list their
        assumptions on how they will meet the design schedule milestones.
    17. Produce a preliminary Construction Cost Estimate for the major elements of the project.
        The TRIP-I FTP documentation should include bid tabs for the work that was performed for the
        Port. This is a good place to start in developing a project construction estimate. The teams
        could also use industry estimating resources such as MEANS to estimate construction costs.
        They should also include %s for various project administration expenses including inspection,
        project management, support to construction and list their assumptions and costs accordingly.
        These are heavily experienced-base, so note how you deal with this issue and what assumptions
        you made.

Spring Term – Design development

    1. Design Swigert Way and Graham Rd. including final alignment (vertical profile and horizontal
       alignment), pavement sections, curbing, landscaping, utility placement, drainage handling,
       and street lighting.
    2. Design storm drainage for the expanded roadway system and include capacity for drainage
       from new impervious surfaces related to property development. Include treatment facility for
       street drainage.
    3. Design intersection of Graham Rd. and Sundial Rd. per the traffic study, including traffic signal,
       ADA accommodation, transit and truck access, and other elements, as developed during
       winter term.
    4. Design wetland replacement project to compensate for wetlands lost due to future lot
    5. Design manufacturing and office building(s) identified in project scope, including surcharging,
       if applicable, to the type of structure designed. Show details for foundation system, shell
       structure, roof structure and support details for the bridge crane. Also, address parking,
       street access for pedestrians, transit, trucks and autos. Provide structural design for office
       space. Address LEED, sustainability, and alterative energy issues, as appropriate.

These project requirements are reflective of a real life project that engineers encounter in the course of
professional work. Projects of this scale have many complexities and the direction and parameters
presented to the engineer aren’t always clear. It is the engineer’s responsibility to understand the
general nature of the problem, assemble a team of professionals who have the necessary expertise,
define the specific direction and project elements and deliver the design package.

The OSU teams need to focus their efforts on the task but also realize that in many cases the client relies
on the engineer to ask the right questions to help guide the client through the design development
process. When developing a project within a municipal jurisdiction, especially one that is a designated
superfund site, there are many complex issues that influence the ultimate design solution and impact
the delivery of such a project. Being able to identify those potential impacts will benefit the design team
in avoiding unanticipated delays or wasted design effort and thereby result in a more successful project.
