OBJECTIVE The purpose of this notification is to inform contracting firms of an upcoming stormwater infrastructure project in downtown Fort Collins. The City of Fort Collins intends to solicit Requests for Proposals (RFP) from qualified firms to provide General Contractor services and work with the City of Fort Collins (City) and its engineering consultant on the design and construction phases of the Oak Street Stormwater Improvements Project (OSSP). Contractor services for this project may include design and preconstruction support such as cost estimation, risk assessment, constructability review, and construction services for water, wastewater and stormwater capital improvements. Firm (Contractors and subcontractors) qualifications will generally include: experience installing large diameter (60" or larger) stormwater systems, water distribution and sanitary sewer collection system construction; knowledgeable about working in constrained urban environments and working for municipalities; and experience with alternative project delivery methods. Firms must have the ability to perform or subcontract work and effectively manage subcontractors. Such work may include tunneling, installation of green infrastructure (or LID systems) along with detailed streetscape installations and landscaping. II. PROJECT INFORMATION Flood hazards in downtown Fort Collins are generally caused by the inability of the existing streets and storm sewers to adequately convey storm runoff from moderate to large storm events. The OSSP is one of several stormwater projects that have been identified as part of the overall Downtown Stormwater Improvement Program and will contribute to resolving urban flooding issues in downtown Fort Collins. Through previous analysis, it has been determined that the new stormwater systems are to be sized to convey the 100-year storm to significantly reduce street flows and the associated flood risks. The OSSP project is an extension of the Oak Street Outfall that was previously constructed in 2001. The project will extend west on Oak Street from Mason to Jackson Street (approximately 6500 linear feet on Oak Street). There will be a total of over 8500 linear feet of new stormwater mains installed, ranging in size from 48” to 78” diameter, which includes several “lateral” extensions from the main on Oak Street, north to Mountain Avenue or south to Olive Street. The system will be designed to integrate stormwater quality in the form of green infrastructure within updated streetscaping in the right-of-way, where appropriate. Significant features of this project include: 1. This is large diameter storm sewer system with large junction structures and pipe, to be installed at significant depth in some areas, requiring specialized knowledge and experience installing infrastructure of this type.

The alignment will cross the Arthur Ditch (at Whitcomb Street) and Shields Street (a major arterial street). Both crossings will require alternatives analysis to determine sound constructability with the least amount of risk, while meeting the requirements of the Ditch Company and City Traffic Department for road closures, while also being mindful of cost and schedule. 3. The project is located in the downtown Fort Collins area where the existing right-of-way can be constrained with other utilities, trees and parking; and where continuous coordination and accommodation with other users of the right-of-way, including business owners, residents, pedestrians and traffic will be required. 4. The size and scope of this project is likely to impact other utilities including water distribution and sanitary sewer collection mains. There are several mains in the area that have been identified in the City of Fort Collins Water and Wastewater Masterplan as needing replacement due to poor condition or age. The mains may also need to be relocated to accommodate the new storm system. Specific water and sanitary sewer work will be identified with the team during design. III. DELIVERY APPROACH The Oak Street Stormwater Improvements Project will be managed using Fort Collins Utilities’ Alternative Product Delivery System (APDS). Experience with the APDS or a similar alternative delivery method of design and construction (CM/GC, CMAR etc.) is critical for the Contractor firm. The Contractor will be part of a project team consisting of the City’s Project Manager(s) and other City staff, and the project engineering Consultant team. The Consultant team was previously selected through a similar competitive selection process. This team will work together from the start of preliminary design through completion of construction. Each team member will have significant involvement in the design and construction concepts that are utilized. Participation by all team members throughout the project is expected to allow innovation and enhance project quality and value. IV. PRELIMINARY SCHEDULE The schedule for the contractor selection process, as well as an estimated milestone schedule for design and construction is shown below. All dates listed below are tentative.
