CEE 12.1 - Performance of Porous Pavement
SPONSOR: Pierce County Public Works Road Operations Division
SPONSOR LIAISONS: Bryan Chappell, Jeff Rudolph
FACULTY ADVISOR: Prof. Carlos Herrera
STUDENTS: Kyler Flores, Fasika Gutema, Pratistha Kansakar, Lisa Stenberg
As part of Pierce County Public Work’s (PCPW) commitment to sustainable development, PCPW is interested in learning more about porous pavement as an alternative to traditional impervious pavement. Porous pavement is a relatively new Low Impact Development technique that is becoming increasingly popular because it allows precipitation to infiltrate where it lands and thus reduces storm water runoff, provides local flood control, and recharges groundwater. Despite the numerous benefits of porous pavement, long-term performance and maintenance costs have not been extensively evaluated. Therefore, PCPW asked the team to examine and compile information on the different aspects of porous pavement. To address PCPW’s request, the team performed four key tasks: (1) prepared a literature review examining the infiltrated water quality, water quantity, pavement durability, best maintenance practices, and the overall cost of porous pavement; (2) evaluated the long-term wear characteristics of existing porous pavements; (3) determined the best maintenance practices for porous pavement through infiltration rate testing; and (4) designed a monitoring system that can be used for future porous pavement installations.
CEE 12.2 - Newhalem Sickler Building Structural Evaluation
SPONSOR: Seattle City Light
SPONSOR LIAISONS: Robert Cochran, Owen Kohashi, Tom Pulford
FACULTY ADVISOR: Prof. Katherine Kuder
STUDENTS: Aimee Corn, TJ Lynam, Maureen O’Sullivan, Rachel Vranizan
The Sickler Building is a steel warehouse owned by Seattle City Light (SCL), located in Newhalem, WA. The warehouse currently functions as an office, gymnasium, and storage facility of key replacement parts for the three dams SCL operates along the Skagit River. Originally constructed in northeastern Washington, the warehouse was later moved to its current location. During reconstruction, the warehouse underwent multiple modifications, without adequate structural analysis. Considering that loads in Whatcom County are approximately four times greater than the building was designed for, SCL asked CEE 12.2 to confirm whether or not the structure meets codes for snow, wind, and seismic loading. The team analyzed the structure on the basis of the county’s codes, using both hand calculations and computer modeling in SAP 2000. The results of this analysis revealed the capacity of multiple structural elements – such as interior columns, frame joints, and wind girts – to be deficient. To address these deficiencies, the team designed a structural retrofit. The final deliverables to SCL include analysis and design calculations, retrofit design concepts, a cost evaluation, and an executive summary.
CEE 12.3 - Babcock Creek Crossing
SPONSOR: Seattle City Light
SPONSOR LIAISONS: Dan O’ Sullivan, Wanda Schultz
FACULTY ADVISOR: Prof. Jhon Paul Smith
STUDENTS: Collin Cabatbat, Rachel Dang, Cole Franklin, Daniel Richings
Seattle City Light (SCL) owns communication towers as part of the Newhalem Power Complex located in the North Cascades National Park. A temporary modular one-lane steel bridge over Babcock Creek currently provides access to these communication towers. Previous attempts at making a crossing failed due to heavy winter debris flow and spring runoff. Team CEE 12.3 was asked to develop two designs for permanent crossings—one consisting of abutments for the existing modular bridge and the other consisting of a new vented-ford crossing. The team has provided designs for both structures along with cost estimates and construction plans. SCL will assess the team’s recommendations on structural longevity and cost-benefit and decide which option will serve as a viable crossing.
CEE 12.4 - Real-Time Control in Stormwater Management
SPONSOR: King County, Seattle University
SPONSOR LIAISON: John Phillips
FACULTY ADVISOR: Prof. David Jacobs
FACULTY LIAISON: Prof. Wes Lauer
STUDENTS: Emily Berg, Cindy Halim. Nicole Nakaoka, Anneliese Sytsma
King County and Seattle University’s shared interest in the improvement to stormwater management tools has led to the investigation of real time control in stormwater management for combined sewer overflow (CSO) control. OptiRTC, a new real time control technology developed by GeoSyntec Consultants, Inc., presents the ground-breaking possibility of operating a detention tank and a rainwater harvesting cistern in the same tank structure. The focus of the project was to evaluate the performance of an OptiRTC valve on the detention tank at Sullivan Hall Law Building on the Seattle University Campus. This retrofit will serve as a means for further research and implementation of OptiRTC technology in King County and presents a stormwater harvesting opportunity for Seattle University. The team developed an EPA SWMM5 hydraulic model of the existing conditions of the Seattle University campus in order to evaluate the effect of OptiRTC control on system performance. The team also developed construction documents for the proposed valve installation. The student design supported the acquisition of a grant from the Water Environment Research Foundation (WERF) that will allow Seattle University, in partnership with GeoSyntec, to install the valve during summer 2012. The team also evaluated two rainwater harvesting options which would allow Seattle University to utilize the new on-campus cistern created by the installation of the OptiRTC valve.
CEE 12.5 - Snohomish County Pavement Management Report
SPONSOR: Snohomish County Public Works
SPONSOR LIAISONS: Joyce Barnes, Max Phan
FACULTY ADVISOR: Prof. Ryan Avery
STUDENTS: Ryan Adachi, Ethan Belen, Daniel Pichardo, Hannah Rolston
Snohomish County Public Works requested a pavement management report to effectively prioritize repairs and manage funds. Prior to the completion of the project, the Airport, Parks and Facilities departments did not have an inventory of documented pavement distress data for the existing conditions of low volume roads, trails and parking lots under their jurisdiction. Through walking surveys of the designated paved areas, Team CEE 12.5 has constructed a comprehensive pavement management report, which includes distress data, pavement condition scores, preservation methods, prioritization recommendations, and a cost analysis for improvements at each location. In addition, a detailed reconstruction was designed for the site requiring the most extensive repairs. All rehabilitation designs are compliant with Washington State Department of Transportation and other relevant guidelines, as well as existing site constraints and appropriate performance goals.
CEE 12.6 - Hydrologic Modeling for Dam Removal on the Elwha River
SPONSOR: U.S. Bureau of Reclamation (USBR)
SPONSOR LIAISONS: Jennifer Bountry, Tim Randle
FACULTY ADVISOR: Prof. Wes Lauer
STUDENTS: Kevin Cook, Justin Milne, Kristin Pesman, Katrina Schwab, Jim Shannon
The Glines Canyon and Elwha Dams, located on the Elwha River on Washington State’s Olympic Peninsula, are being removed as part of the largest dam decommissioning project in United States history. To support the project, the U.S. Bureau of Reclamation (USBR) requested that Team CEE 12.6 develop a tool to quickly evaluate changes in discharge and reservoir water levels associated with potential modifications to the dam removal and reservoir drawdown schedule. In response, the team developed a computer model that routes flow through each reservoir. The program accounts for potential changes in the geometry of the overflow structures and predicted changes in reservoir geometry caused by sediment redistribution. It also links with flow forecasts published by the National Weather Service’s Advanced Hydrologic Prediction Service. The tool allows USBR to ensure that drawdown rates remain within safe limits that minimize downstream impacts, reduce landslide risk, and track how redistribution of sediment within the reservoirs affects reservoir routing.
CEE 12.7 - Elwha Sedimentation Impact Project
SPONSOR: U.S. Bureau of Reclamation (USBR)
SPONSOR LIAISONS: Jennifer Bountry, Tim Randle
FACULTY ADVIDOR: Prof. Wes Lauer
STUDENTS: Mark Beggs, Marshall Kosaka, Anna Sigel, Renee Vandermause
The Elwha and Glines Canyon Dams, located on the Elwha River near Port Angeles, WA, are currently being deconstructed as part of a plan to restore the Elwha River ecosystem. When the dams are removed, a portion of the 24 million cubic yards of sediment presently trapped within the reservoirs will begin moving downstream. The U.S. Bureau of Reclamation (USBR) has developed an adaptive management plan to address unexpected responses to the sediment pulse. To support the plan, USBR requested that the team analyze the potential hydraulic effects of a range of sedimentation scenarios on the Lower Elwha River. The team performed a preliminary analysis using an existing one-dimensional hydraulic model (HEC-RAS) and then created a two-dimensional hydraulic model (SRH-2D) that incorporated recent geographic, bathymetric and surveying data. The team’s final deliverables include one and two- dimensional models, as well as design recommendations for using water level measurements at several sites along the lower river to update the USBR’s adaptive management plan.

The prototype features three switches, which the driver can use to select between each noise source inside the truck. Adaptive filtering, in conjunction with microphones to produce noise references, was used to reduce each noise source.
ECE 12.3 - Micromouse Competition
SPONSOR: Seattle University
FACULTY ADVISOR: Prof. Al Moser
STUDENTS: Shannon Hitchen, Chris McDougall, Bobby Seidensticker, Hoang Tran
The Institute of Electrical and Electronics Engineers (IEEE's Micromouse competition challenges contestants to build a robot capable of autonomously mapping a maze, determining the fastest route from start to the center, and running that route as fast as possible. Seattle University had no solid infrastructure for competing, so it was the team's task to create a viable entry for the competition. The team was also tasked with creating a second robot so more students can work on the project in the future. The robot is based around a microcontroller that gathers information of its surroundings using infrared sensors. It processes the data and sends the appropriate Pulse Width Modulated signals to a motor controller board, which amplifies those signals to drive the motors. The robot uses a Flood Fill algorithm to fully explore the maze, and a weighted version to find the fastest route to the center. The team's robot took 1st place at the competition, with a speed run time of 27.5 seconds.
ECE 12.4 - Pulse Oximeter Probe Adapter
SPONSOR LIAISON: Paul LaBarre
FACULTY ADVISOR: Prof. Paul Neudorfer
STUDENTS: Ali Alaoui, Ferdy Kwee, Justin Shimasaki, Soroath Viseth
The mission of PATH is the application of technology to provide and improve healthcare in underdeveloped countries around the world. This project focuses on pulse oximetry, the measurement of a patient’s blood oxygen levels. Hospitals and clinics in underdeveloped countries often receive donated equipment, including pulse oximeters. After long periods of use the equipment will naturally fail. This can result in a diverse assortment of incompatible and unused equipment. In the case of a pulse oximeter, the failure can be with either the oximeter itself or the probe, which is fastened to the patient’s finger. The team was tasked with developing an adapter that will allow the usage of one probe (from the GE Tuffsat) with up to three different pulse oximeters from different manufacturers. This interface allows probe and machine to communicate with one another. The success of this project will enable developing countries to make full usage of their mixed and matched pulse oximetry equipment.
ECE 12.5 - Seattle University Broadway Garage Count System Design/Redesign Project
SPONSOR: Seattle University
SPONSOR LIAISONS: Jay Heitman, Byron Lynch, Mike Sletten
FACULTY ADVISOR: Prof. Margarita Takach
STUDENTS: Daniel Leng, Long Ly, Adhanom Debas, Aziz Yuldashev
Seattle University’s Broadway Garage is heavily used by students, staff and guests. To monitor the use of the garage and display the estimated number of vacant parking spaces, the Department of Public Safety incorporated a vehicle count system. The count system proved to be flawed, as it would miscount the number of vehicles in the garage, thus misinforming motorists of its vacancies. Seattle University has asked the team to redesign the vehicle count system to make it more convenient for motorists to access the garage, as well as to monitor activities in the garage. The team has redesigned the count system using parts from the previous system, inductive loops in the floor and the addition of photoelectric light sensors to enhance the proficiency and accuracy of the system. The newly designed system produces a count of vehicles with a combination of two sensors.

The tube prototypes use (1) conventional woven carbon fiber epoxy and (2) carbon fiber interlaced with carbon nanotubes. Testing on nanotube prototypes will support recommendations to be made concerning the use of composite materials for hydraulic tubes in Boeing aircraft
ME 12.2 - Energy Efficient Lighting for Manufacturing Facility
SPONSOR: Kenworth Truck Company
SPONSOR LIAISON: Vincent Brown
FACULTY ADVISOR: Prof. Bob Cornwell
STUDENTS: Adrian Kirn, Theodore Lyons, Joshua Sandy
Kenworth Truck Company, a division of PACCAR Inc., operates a truck assembly plant in Renton, Washington. Kenworth asked ME 12.2 to develop a system to both reduce the energy consumed by the lighting system and supplement the existing power with renewable energy. The team studied current and development-stage technologies in solar power generation, motion sensing lighting controls, and high-efficiency light sources. The study indicated that the most cost-effective solution would be a combination of all three approaches. The team designed an adjustable frame for the solar panels to maximize the overall efficiency by increasing the total incident light on the panels. A motion sensing system was designed for the factory warehouse to limit the overhead lighting when possible. A number of energy-efficient lighting fixtures were studied with the goal of reducing the lighting load by up to 40%. The modular design of the proposed system meets Renton’s industrial building codes, reduces lighting costs, and can be selectively implemented to maximize the return on investment.

Photon Machines, Inc. designs and builds laser-based instruments for performing chemical composition measurements. The company's current product line consists of two desktop systems that use a technique known as Laser-Induced Breakdown Spectroscopy (LIBS). LIBS uses a high intensity laser to generate a plasma on the surface of an analyzed material. The plasma emits light that is collected and used to identify composition based on characteristic wavelengths. Photon Machines requested that Team ME 12.3 design, prototype, and test a portable instrument that fits into a backpack and can be operated by individuals with minimal training. The team assembled a 32-pound prototype using only the essential components required to perform accurate and repeatable measurements, including a computer, high-intensity laser, 1-channel spectrometer, heavy-duty backpack, lithium-ion battery, digital camera, and LCD touch screen. The functioning prototype correctly discriminates between common metal samples based on chemical composition.
ME 12.4 - Hybrid Waste-to-Energy System Design and Feasibility Analysis
SPONSOR: PSF Mechanical, Inc.
SPONSOR LIAISONS: Jim Reynolds, Randy Tuminello
FACULTY ADVISOR: Prof. Kevin Chadwick
STUDENTS: Brian Johnson, Taylor Matsui, Benjamin Watson
Every day, more than 1,500 tons of wastes are disposed of in landfills across the Pacific Northwest. Each ton of waste contains the potential for approximately 2930 kWHr of energy. Team ME 12.4, in conjunction with PSF Mechanical Inc., researched and developed a prototype system to generate energy from landfill waste. The team analyzed and compared the cost of the prototype system to the cost of existing technology. The prototype system will convert waste into ethanol and electricity via a combined process of gasification, biochemical decomposition, and steam expansion through a turbine. The prototype system uses technology from several different companies, which PSF will integrate into a hybrid system to build waste-to-energy plants at several transfer stations. INEOS Bio, a petrochemical production company, has expressed interest in pursuing development of a local plant using their proprietary technology. It has been determined that an existing plant design from INEOS Bio will be more feasible for PSF than investing in the development and implementation of a system of their own.
ME 12.5 - St. James Cathedral Energy Audit and Retrofit
SPONSOR: St. James Cathedral
SPONSOR LIAISONS: Larry Brouse, Dave Perozek, Jack Southall

FACULTY ADVISOR: Prof. Teodora Shuman
STUDENTS: Ellen Ruotsala, Katherine Stinson, Madona Youssef, Sylvana Youssef
St. James Cathedral, built in 1907, is a historic landmark in the urban center of Seattle. The cathedral provides daily religious and civic services to the community and is looking to reduce its energy costs as well as improve its carbon footprint. The cathedral’s heating system uses steam produced by Seattle Steam Co. and electricity from Seattle City Light. The steam system has recently been improved by adding a preheating coil to the supply air duct, thus maximizing heat transfer. The cathedral has converted from incandescent to compact fluorescent bulbs for ambient, flood, and outdoor lighting, while lighting in the worship areas remains high-wattage incandescent. Despite these recent improvements, the cathedral still spends $60,000 per year on energy, with 60% going to steam and 40% to electricity. To address these high-energy costs, Team ME 12.5 conducted an energy audit. The audit analyzed the building’s lighting and heating systems, as well as areas of heat loss through the structure. Using the results of the audit, several energy conservation measures were proposed, including: adding solar panels, switching the heating system to either a condensing boiler or ground source heat pump, and adding insulation. The energy savings of each measure was found using computer models developed by the team from billing, structural and annual weather data. Each solution was analyzed based on equipment, installation and operational costs, efficiency, reliability, and carbon footprint.
ME 12.6 - Cooking Exhaust Fan Systems Project
SPONSOR: Seattle University Facilities
SPONSOR LIAISON: David Brugman
FACULTY ADVISOR: Prof. Mike Larson
STUDENTS: Bikramjit Bhangoo, Rodney Dwyer, Edward Guevara, Daniel Tunay
Seattle University Facilities Services is responsible for the maintenance and improvement of the university’s campus. They have found that the kitchen exhaust systems of the Casey building, Chardin Hall, and Cherry Street Market are not energy and cost efficient. Of the three systems, the Cherry Street Market kitchen consumes the most energy every year. Facilities Services has requested that Team ME 12.6 perform an energy analysis of the system in the Cherry Street Market and propose improvements to reduce the energy costs. The improved system proposed by Team ME 12.6 includes: adding side panels to the hoods, lowering the makeup air temperature by 10 degrees F, installing variable frequency drives on the fan motors, and modulating the gas burners. These improvements will increase the efficiency of the original system and reduce the energy consumption, resulting in a payback period of much less than the stated target of 10 years.
