Project Description:
The CEDE - Civil Engineering Department is requesting a proposal from the group of student engineers to provide comprehensive engineering efforts and services related to the upcoming Sharp Avenue permeable pavement reconstruction project. Permeable pavement systems are to be used in the reconstruction for Sharp Avenue in the spring of 2017. The City of Spokane is interested in including several permeable pavement test section configurations along Sharp Avenue as part of this project. This project represents the second phase of a multiyear collaboration between the City of Spokane and Gonzaga University.
Permeable pavement remains an experimental low impact development (LID) and best management practice (BMP). Permeable pavement, as an LID, has the goal of mimicking the natural hydrological processes by treating and/or infiltrating stormwater as close to where it falls to the ground as possible. This type of system has the potential to effectively treat stormwater, as it percolates through the pavement and ground, while eliminating or reducing the need for conventional stormwater sewer systems currently used in urban settings.
The project will produce a final report, among other deliverables to submit to the sponsor (City of Spokane). Additionally, the student participants will prepare one or more conference or journal publications. Students will be responsible to make required presentations of the project activities and may also attend an appropriate conference.
EVALUATION PROCESS
The proposal evaluation process will be determined by the project advisor in conjunction with the CEDE, the project sponsor, and the CEDE Design Advisory Board. It will be based on the organization of the project efforts reflected in the proposal and the educational goals achieved in the completion of the proposal. Note that some efforts in the project are oriented to achieve educational goals that are not required to achieve the project sponsors goals.
BACKGROUND INFORMATION
Permeable pavement continues to be of interest to the City of Spokane as a potential best management practice (BMP) in the area of low impact development (LID). Students at Gonzaga University (GU) have recently assisted the City of Spokane in understanding the properties and behavior of permeable pavement. During the summer of 2014, GU students completed a Permeable Pavement Feasibility Study (known as Phase I of the forthcoming Sharp Avenue Permeable Pavement Monitoring Study for Sharp Avenue which is slated for reconstruction in 2017). The results of the feasibility study left some questions regarding durability and monitoring procedures that still need to be answered. In particular, while permeable pavement is approved for flow control, Washington State Department of Ecology currently does not approve permeable pavement for water quality treatment due to insufficient data. Thus, to better examine permeable asphalt permeability and water quality treatment effectiveness, we are proposing here field and lab monitoring activities on the upcoming Havana Street Stormwater Improvement project; a proposed section of street between 37th Avenue and Glenrose Road that is to include a new permeable pavement bike path and bioretention areas to improve overall drainage and water management (see Figure 1). The permeable pavement bike path-to-conventional nonporous asphalt pavement is shown in cross section in Figure 2. Additionally, an approximate 20 ft-wide permeable pavement section across Havana Street (at an area to be determined) will be included in the project. We understand the permeable pavement section used in the project will be constructed with the following major components:
· Permeable asphalt surface course: 6-inch surface layer of permeable asphalt.
· Aggregate base course: 7-inch layer of #57 stone base course below the surface course.
· Filter sand bed: A 12-inch filter sand layer placed below the base course.
The goal of this monitoring study is to help inform, refine, and finalize the design, construction, and monitoring plans and procedures to be used on the 2017 pavement installation along Sharp Avenue and to assess the runoff treatment benefits of permeable asphalt. These goals will be achieved through the analysis of data collected in both the field and laboratory during the Havana Street project. The data collected will be as a result of monitoring the permeable asphalt installation and obtaining/testing core samples pulled from the pavement section at various areas of the project area. Specifically there are four objectives for this study:
1) Evaluate permeable asphalt construction practices and as-built permeable asphalt pavement design criteria and infiltration performance properties through laboratory evaluation.
2) Evaluate the short-term durability of the permeable pavement section (bike lane and strip constructed across the street) under typical environmental conditions and Havana Street traffic loadings and conditions (e.g., cyclical subgrade movements, winter maintenance, street cleaning, heavy truck traffic, etc.) expected in this area of Spokane.
3) Evaluate infiltration capacity in the field related to potential clogging and evaluate and determine the best maintenance activities to regenerate infiltration capacity after clogging.
PROJECT INFORMATION AVAILABLE
The project team must familiarize themselves with the project in order to properly prepare the project proposal. Two documents should be consulted, one being the Sharp Avenue Feasibility Study, and the second being the final report produced by the Sharp Avenue senior design team in 2014-2015. Additional technical documents, outside of the scope of the feasibility study, may need to be reviewed as well.
STUDENT PROJECT ACTIVITIES REQUIRED
The student project group will, at a minimum, provide the following efforts and deliverables in the completion of the project addressed in this proposal:
Scope of Activities Required to Meet Project Goals
Task 100 Project Management and Coordination
The student group shall organize, manage, and coordinate the efforts required to accomplish the project using standard project management and contract administration techniques. Key management activities are identified below:
Sub-Task 110 Kick-off Meeting
The Student Team will conduct a kickoff meeting with their project advisor and sponsor liaisons to gain familiarity for the project and to solicit input, gather available data and information.
Sub-Task 120 Routine progress-review meetings
Routine progress-review meetings will be conducted on a regular basis as follows:
a. Weekly progress reports are required and are to be submitted electronically to the advisor by 5:00 pm each Thursday. Weekly progress reports must include, at a minimum, activities completed by each team member for the current week, expected work for the upcoming week, and updates to the project design budget and schedule.
b. In addition, a complete hardcopy record of the project reports and files must be maintained by the student team and be made readily available during consultations with the advisor. Typical method would be a project notebook. The advisor and liaison will ask to review this notebook periodically to discover the status of the work being completed.
Sub-Task 130 Regular Advisor and Liaison Meetings
In subsequent meetings following the initial project kick-off meeting, the Student Team will meet weekly with the project advisor, and will also meet when needed with the project liaison(s). All meetings with advisor and liaisons MUST be arranged by members of the Student Team in advance (at least 2 days prior) and include a proposed meeting agenda sent to the advisor and/or liaison prior (at least 2 days) to the meeting. All meetings must be documented by the Student Team in the form of meeting minutes with copies of the minutes distributed within 3 days following the meeting to all team members and the project advisor and liaisons.
Sub-Task 140 Quality Assurance/Quality Control
The Student Team will perform a methodical QA/QC effort in a manner suitable to the project advisor and liaison, to prevent incorrect, sub-standard or dangerous results from being included in the end of semester project reports.
Sub-Task 150 Project Schedule / WBS /Gantt Chart
The proposal must contain a Gantt chart that shows the due dates from the CEDE schedule (shown in this document later) as milestones, each sub-task, the duration of time proposed to complete the subtask and the team member responsible for the subtask.
The student group will include a “proposed” budget that details the costs of completing the project design tasks. This budget is not the “engineers construction cost estimate” to complete the implementation of the design; rather, it is the costs to perform the engineering tasks and includes the fictitious value of project team personnel hours. The value of the personnel hours and other associated costs (travel, books, etc.) will be the proposed budget and will simulate the budget a consulting group would charge to complete the project.
Task 100 Deliverables
- Electronic copy of agenda for team meetings.
- Electronic updates to project design budget and schedule that includes budget and personnel hours for each sub-task in the entire project.
- Electronic copy of resolutions and action items for each meeting (meeting minutes).
- Statement on the QA/QC activities for reports submitted at the end of each semester to describe the review and checking procedure employed.
Task 200 Project Data Collection
Review the feasibility study (completed in the summer of 2014) and the 2014-2015 senior design report. Work collaboratively with project liaisons to develop project data suitable for completing all monitoring tasks at Havana St. Data collected (beyond the feasibility study) may include additional information from state and municipal transportation agencies, additional literature review on the behavior and monitoring of permeable pavement, and other data and testing. Existing data that is available will be provided by project liaisons.
Subtask 210 – Feasibility Study and 2014-2015 Senior Design Final Report Review
Subtask 220 – Using results of a literature search, determine key monitoring questions to be answered and proposed monitoring procedures to be implemented.
Subtask 230 – Based on examining site conditions, determine monitoring locations along Havana St.
Task 200 Deliverables
- Electronic and/or hard copies of literature, data, reports, testing, and surveys completed for the project and to be included in the project report.
- Monitoring objectives and monitoring plans and procedures to meet those objectives.
- Suitable sites for monitoring locations.
Task 300 Construction Inspection and As-Built Condition Evaluation of Havana St. Permeable Pavement (to meet Objective #1)
Subtask 310: Construction Inspection and Development of Construction Inspection Checklist for Sharp Avenue Project.
Provided construction of the Havana St. permeable pavement sections (bike path and full width section) is undertaken in early October at the latest, the student team will coordinate with the City of Spokane Inspectors to complete a construction inspection of the placement of permeable asphalt along Havana St. The inspection will be completed to document the construction process and evaluate how well it follows the suggested construction techniques that were discovered during the Permeable Pavement Feasibility Study. It is critical for the student team to coordinate these inspection activities with the City of Spokane to ensure that proper inspection procedures are followed in the field and when interacting with contractors.
Subtask 320: Havana St. Permeable Asphalt As-Built Condition Survey and Evaluation:
The student team will survey and collect pavement data using ASTM standards as guidelines (e.g., pull cores and measure layer thicknesses, test for permeability and air voids content, etc.) to define the as-built properties of the Havana St. permeable asphalt sections. The team will compare the as-built condition to the design and identify any discrepancies or issues that might have arisen during the construction process. This information will be valuable to guiding the construction process of the full-scale Sharp Avenue project in 2017.
Task 300 Deliverable(s) – Student draft(s) by December 2015, Recommendations to the City by Feb 2016
· Final permeable asphalt construction inspection checklist to document and guide inspection of the permeable asphalt construction process for Havana St. and Sharp Avenue.
· Documentation of as-built pavement material parameters and hydrologic performance of the Havana St. permeable asphalt immediately after its installation.
· Report summarizing the construction process and the as-built condition of the permeable asphalt pavement and the identification of possible construction related issues with respect to hydrologic performance and durability.
Task 400 Evaluation of short-term permeable asphalt durability under typical Havana St. traffic and maintenance conditions (Objective #2)
Subtask 410: Visual Observation of Pavement Distress
The permeable asphalt on the bike path will still be subjected to movement of the ground, freeze-thaw, etc., while the permeable asphalt section for the strip across the street will include the environmental conditions as well as traffic loadings with and without studded tires. Both the environmental conditions and traffic loadings cause strains within the pavement section(s) and generally lead to damage on pavement surfaces over time. The pavement section(s) will be visually monitored for signs of obvious distress during the observation period. The severity, extent, and type of pavement distress will be measured and recorded over the short term to document the pavement’s response to a typical cycle of weather in Spokane. Some of these changes in the pavement will be visually obtained following guidelines adapted from the WSDOT Pavement Surface Condition Rating Manual.
Subtask 420: Testing of Material Behavior using Core Analysis
Testing of material behavior, using cores sampled, will also be completed to look at changes in air void content, unit weight, and other parameters over time. The team will coordinate with the City of Spokane to complete a variety of testing on pavement cores utilizing both the GU Soils laboratory and a City approved geotechnical laboratory for select testing that is beyond the capabilities of the GU lab.
Task 400 Deliverable(s) - Drafts by December 2015 and February 2016. Final memo, draft manuscript, and recommendations to the City by May 2016.
· Memo describing the results of the observations on durability and any recommendations that can be provided to the City of Spokane on potential design changes that can maximize the durability performance of the Sharp Avenue project.
· Draft manuscript documenting the durability of the permeable asphalt section(s) on Havana Street when exposed to traffic loadings (with studded tires) and short-term environmental conditions. Results should provide preliminary recommendations to the City of Spokane on potential design changes that can maximize the durability performance of the project sections for the forthcoming Sharp Avenue reconstruction project.
Task 500 Evaluation of Havana St. Permeable Pavement Infiltration Capacity and Regenerative Maintenance Practices over Time and After Forced Clogging
Subtask 510: Research and Develop Monitoring Objectives, Plans, and Procedures for Evaluating Infiltration Capacity along Havana St.
The student team will research and develop additional monitoring plans and procedures that can be used on Havana St. to evaluate infiltration capacity of the permeable asphalt pavement over time and after direct and forced clogging (i.e., direct application of dirt to clog the pavement surface, accidental dumping of mulch, etc.).
Subtask 520: Evaluate Infiltration Rates and Regenerative Maintenance Practices
The team will evaluate infiltration rates before and after different maintenance activities to help identify the best maintenance practices to apply to regenerate the permeable pavement surface over time. The student team will use ASTM C1701 to measure infiltration rates over time and can also take advantage of any adjacent fire hoses to simulate rain events as necessary. Results should provide recommendations to the City of Spokane on potential design changes or maintenance activities that can maximize the hydrologic performance and maintenance of the full scale Sharp Avenue project sections.
Task 500 Deliverable(s) – Monitoring project plan by October 2015, draft reports by December 2015 and February 2016 and draft manuscript by May 2016.
- A draft manuscript documenting the monitoring objectives, monitoring procedures, results, and recommendations/conclusions that can be submitted to a peer-reviewed journal or conference proceedings.
Task 600 Project Sustainability Evaluation
Based on the City of Spokane’s needs (as well as those of the residents of Spokane and the surrounding area), evaluate the Havana St. project tasks with respect to the overall sustainability of the project, and identify other opportunities for increasing sustainability that are potentially achievable for the upcoming Sharp Avenue reconstruction project.
Task 600 Deliverables
- Provide an appropriate written presentation that:
a) Describes the environmental, social, and economic benefits/costs of the project.
b) Provide a summary commenting on the sustainability of the methods used to meet the project goals.
Task 700 Project Impacts on Society
The final report submitted for the project will include a discussion, using properly sourced references on what impacts the implemented project will have on the residents in the immediate project area, as well as those residing in the broader, region. (e.g., use of taxpayer funds, water quality, etc.)
Task 800 Project Reports, Publications, and Presentations
The project will require a written proposal, progress report, final engineering report, draft conference or technical journal manuscripts, and several oral presentations on progress.
Task 800 Deliverables
- Proposal will include a project description, proposed tasks, expected timeline, and design cost estimate and will be due during the first semester of work. This proposal must define a specific timeline (Gannt Chart) for deliverables and responsibilities of personnel for each of the design tasks.
- A Progress Report will be due at the end of the Fall semester and will outline the progress that has been made on the project.
- A Final Design Report will be due at the end of Spring Semester and will include: (1) an executive summary, (2) a comprehensive report detailing the approach taken to achieve the project objectives, and (3) any supporting documentation.
- Draft technical manuscripts (to be submitted to conference or technical journal) dealing with the project will be due at the end of the Spring Semester.
