The City of Manhattan is seeking qualification submissions from highly qualified, registered engineering firms that provide innovation and experience in municipal engineering, sanitary sewer system modeling and flow meter data analysis for wet and dry weather conditions, design and construction, utility relocation, and easement/right-of-way acquisition. The consulting services will include analysis and engineering design for Seth Child Sanitary Sewer Interceptor Improvements.
This project was been identified in the 2015 Wildcat Creek Sewer Model Report and includes sanitary sewer capacity improvements for approximately 2,700 linear feet of 12-inch sanitary sewer main from Beechwood Terrace, through the Westloop Shopping Center and to Garden Way. A map of the sanitary sewer section to be improved has been included. This section of 12-inch sanitary sewer has been identified in the report as being over capacity during wet weather flows and needs to be upsized to an 18-inch interceptor main.
II. SCOPE OF PROJECT
The findings of the 2015 Wildcat Creek Sewer Model Report were based on flow metering data collected at the downstream of the sewershed. The first phase of this project will include a preliminary engineering analysis to further assess and verify the need for the project with additional sanitary sewer flow metering data from within the basin to be collected, analyzed and modeled. The deliverable report of the preliminary analysis shall include the findings of the assessment and may include recommendations of alternative methods of wet-weather flow reduction in lieu of capacity improvements and/or cost-benefit analysis of using non-traditional or in-situ construction methods to reduce impacts to established developments, businesses, residences or other infrastructure. Based on the conclusions of the preliminary engineering assessment, an agreement to complete final design may be negotiated.
Submittals should focus on the consultant’s capabilities for providing services which include, but are not limited to the following project components:
• Collection, evaluation and assessment of sanitary sewer flow metering data.
• Reduction of inflow and infiltration of stormwater and groundwater into a sanitary sewer collection system.
• Design of non-traditional or in-situ sanitary sewer construction methods that reduce impacts to established developments, businesses, residences or other public/private infrastructure.
• Design survey services. Scope will also include additional survey beyond the construction limits to collect sufficient data for critical structures relevant to determining future design connections.
• Prepare construction plans, submittal packages, and cost estimates.
• Include right-of-way and easement acquisition services as needed.
• Utilities Conflict Management and Relocation, if necessary
• Environmental Clearances
Submittals should demonstrate the consultant’s experience leading efforts for similar projects. A contract and detailed Scope of Work will be developed once the design team has been selected.
The anticipated/desired project schedule is as follows:
• December 10, 2018 Advertise for Proposals
• January 18, 2019 Receive Consultant Proposals
• Week of January 21, 2019 Selection Committee review proposals
• Week of February 4, 2019 Interview Consultants (if required)
• February 19, 2019 City Commission authorize negotiations
• Week of March 4, 2019 Negotiate Scope with selected Consultant
• March 19, 2019 City Commission approves Contract
The City is currently proposing to utilize flow meters, collect sanitary sewer flow data starting in early 2019 and anticipates to collect at least six (6) months of data for use in the preliminary engineering analysis, unless adequate data is obtained within a smaller timeframe. The City desires that all aspects of the preliminary engineering analysis be completed within approximately sixty (60) days after all flow data has been collected, or by October 31, 2019, whichever comes first. If the preliminary engineering analysis further recommends capacity improvements, the City desires that all aspects of design be completed no later than six (6) months upon acceptance of the preliminary engineering analysis by the City, or by April 30, 2020, whichever comes first.
Submittals should include discussion of the team’s ability to meet the desired timeline. A detailed scope of services will be developed as part of contract negotiations. In addition to normal survey and design responsibilities, the Consultant will be responsible for interim review meetings with City and federal stakeholders to receive feedback on coordinating design.
VII. SUBMISSION REQUIREMENTS
All submissions must include the following information:
1. Identification of the Project Director and key team members:
a. List all principal participants, including sub-consultants if any, and responsibilities of each team member.
b. Contact information for the Project Director, including phone and e-mail address.
2. Response to the six key points mentioned in Section IV. Criteria for Selection.
3. Maximum page limit: 20 numbered pages, 8.5x11 pages, excluding cover, table of contents, cover letter and dividers.
