City, Airport and Project Overview

I. CITY, AIRPORT AND PROJECT OVERVIEW

The values of equity, diversity, inclusivity, accessibility, and sustainability are inherent to the City’s strategy to develop and maintain prosperous communities. Accordingly, these values are imbedded into all the City’s procurement processes to ensure competitive procurements that offer equitable opportunities for all potential Bidders, including greater contracted and significant participation for historically underutilized businesses to ensure Denver’s long-term economic, social, and environmental health. Through equitable procurements, the City is committed to working to remove barriers and increase access to City contracting opportunities for all historically underutilized and small businesses including those owned by veterans and individuals living with disabilities as well as those in economically distressed or redlined neighborhoods. It is a primary value to promote economic equity by engaging a more inclusive community of Bidders and contractors, both as prime and sub-contractors to address socioeconomic disparities. Through this promotion of equity and inclusion (EDI), the City strives to improve opportunities that ensure fair and just access to jobs, housing, education, mobility options, and healthier communities. It is the City’s expectation that all successful Bidders demonstrate their commitment to these City values through their procurement responses and post contract and/or lease activities.

Each procurement opportunity is to be approached with ethical and honest behavior. The City will solicit, evaluate, and award contracts based upon the Proposer’s alignment with the City’s values as it relates to its approach, proven experience, ability to perform work, costs, and pricing. DEN is looking for Proposers that demonstrate a history of equity, diversity, integrity, stewardship, innovation, and humanity. The City is looking for Proposers that have equity, diversity, and inclusion (EDI) embedded in their policies, procedures, practices, initiatives, and exhibit actionable results and ensures that of those that they partner with.

The City’s values may be demonstrated through but are not limited to: (a) workforce expansion; (b) utilization of and work with the historically underutilized community, separate from required certified goals; (c) environmental sustainability and (d) EDI and Equal Employment Opportunity (EEO) programs for staff.

DEN plays a unique role as a gateway to the world for the region, our passengers, our communities, and our partners. As such, DEN has a generation of operators, concessionaires, designers, builders, planners, and small businesses that are stronger and more successful because of this work. DEN has also helped build new businesses that have flourished and grown into mature industry leaders. As part of its new Vision 100 plan, DEN intends to expand this legacy by looking to the community that has succeeded in the past at DEN to bring the next generation forward.

In its review of this contract opportunity, DEN believes that the scope of work and firms in the industry lends itself to unique partnership opportunities, and therefore, encourages firms that have historically proposed as prime contractors to serve as subcontractors to M/WBE firms in their contract with DEN, or to create Joint Ventures with M/WBE firms. A focus of this partnership should be for the contracting partners to build a meaningful relationship that is not merely transactional to meet a numerical goal. The objective is to afford the M/WBE firm the opportunity to learn from the large contractor, grow its financial capacity, build its generational wealth and its portfolio, and increase its capability to perform new commercially useful functions on future contracts.

In accordance with procedures described herein, you are hereby invited to submit a proposal for the subject project, which is described in the Scope of Work incorporated herein. The work under this Contract is anticipated to start on or about October 2025 and has a scheduled duration of Five (5) Years

City, Airport and Project Overview from Date of Execution (DOE). The proposal must be prepared and submitted in accordance with the requirements and procedures contained in this RFP document and the City’s, including DEN’s, ordinances, rules, policies, and procedures. Compliance with these requirements by the Proposer is mandatory and is a condition of responsiveness. Any failure to satisfy these requirements will be a sufficient basis for the City and County of Denver’s Department of Aviation, also known as Denver International Airport, (DEN or City) to disqualify the Proposer. The City shall not be liable for any of the Proposer’s expenses associated with its preparation of the proposal or DEN’s consideration of it. The Proposer, if selected, shall not include any such expenses as part of its fee for performing the Scope of Work.

Scope of Work

II. SCOPE OF WORK

SECTION 1

PROJECT SPECIFIC INFORMATION

A. PROJECT INTRODUCTION

Denver International Airport (DEN) is a commercial air carrier facility located 23 miles northeast of the metropolitan Denver area. Located near the geographic center of the United States, DEN is the only major hub airport within a 500-mile radius and offers nonstop flights to more than 200 destinations. Therefore, DEN attracts passengers from all over Colorado as well as significant passenger numbers from the Mountain States and Midwest. DEN also has service to approximately 20 Federally subsidized Essential Air Service (EAS) routes across the Western and Midwest U.S. making DEN the only air service option for these rural markets. Transit is currently not a viable option for a significant number of the passengers traveling to DEN, therefore Peña Boulevard remains essential for connecting travelers to the region’s major hub airport.

B. PROJECT BACKGROUND

Peña Boulevard is a four-lane (two lanes each direction) freeway that extends from I-70 to the Jeppesen Terminal at DEN. The roadway widens to three lanes in each direction between the E-470 Tollway (E-470) and the Jeppesen Terminal.

Peña Boulevard was originally constructed almost 30 years ago, as such required maintenance work is extensive, and the cost to maintain the aging facility is substantial. In 2023, DEN served 77.8 million passengers; DEN is expected to serve 100-million annual passengers as soon as 2027. To manage growth, maintain the reliability of the supply-chain and continue to boost the local and regional economy, DEN must rehabilitate Peña Boulevard and address infrastructure deficiencies.

The E470 to Jackson Gap Boulevard stretch is one of the busiest portions of Peña airport traffic as it combines both Peña and E470 traffic. Any emergency pavement failures are crippling to traffic operations and for access to/from the airport.

This stretch of Peña Boulevard originally included a toll plaza for traffic exiting the airport. Peña Boulevard Inbound included a deviation from alignment to allow room for this toll plaza. DEN Facilities has removed the old toll plaza structure. This project will straighten Inbound Peña Boulevard to bring it back on alignment.

This project will also include interchange improvements at the Final Approach development on the north side of Peña Blvd at Gun Club Road. These improvements are anticipation of DEN Real Estate’s continued development in this area. It will include 2 new ramps and other related improvements.

C. PROJECT DESCRIPTION

DEN is seeking a professional consultant to complete the Design Engineering Services for improvements to Peña Boulevard between E-470 and Jackson Gap Boulevard.

This Project involves reconstruction of both Inbound and Outbound Peña Boulevard between E470 and Jackson Gap Boulevard. This includes white topping in most locations, a realignment of inbound Peña Boulevard between E470 and Gun Club, a realignment of the Inbound Gun Club off-ramp.

The following improvements have been identified for the work:

1. Either existing pavement and rubblization and PCCP white toping or full reconstruction of Peña Boulevard.

2. Increase inside shoulder width from 6 feet to 12 feet.

3. Realignment of Inbound Peña Boulevard from E470 to Gun Club Road.

4. Realignment of Inbound Peña Boulevard off-ramp to Gun Club Road.

5. Bridge rehabilitation (3).

6. Removal of old toll plaza pavement in the median.

7. Repurposing of old Inbound Peña Boulevard Gun Club off-ramp to two-way local road.

8. Multi-use trail east from E470 High Plains Trail to 78th/77th intersection.

9. Turning the Inbound Peña Boulevard Jackson Gap single lane off-ramp into a two-lane off-ramp (off and optional).

10. Construction of two outbound off-ramps at Gun Club Road. (West Approach Improvements)

11. Existing ramp tie-ins will need to be modified to meet the new Peña elevation (4).

12. Widening of the Outbound Peña Boulevard bridge over Piccadilly and both Gun Club bridges to accommodate phasing and for future use identified by the Peña Blvd NEPA study.

13. Replacement of all sign bridges and addition of exit ramp overhead signing. One impacted sign includes dynamic parking information and will need communication design.

14. Lighting modifications/upgrades at the old toll plaza location.

15. Phasing plan that allows for 3 lanes of traffic in both directions at all times.

16. Intersection/Signal modifications at the ramp intersection and 75th intersection

D. DESIGN TASKS

1. Conceptual Design The Consultant shall prepare a conceptual (10-20%) design that incorporates the following elements (see attached overall exhibit - Overall conceptual Exhibit – E470 to Jackson Gap):

a. Reconstruction Limits – Limits of reconstruction to be defined by design team analysis that will include a field visit to determine the general pavement condition. The approximate project limit starts at about 200 feet west of the eastern E470 ramp gores and continues along Peña Boulevard to the western edge of the Jackson Gap approach slabs. A separate, early action, “Peña Blvd outbound Low Point” Reconstruction and Drainage Improvement from Picadilly to Gun Club Road Project is not included in this scope. Plans and CAD files for that project will be supplied to the Consultant.

b. White topping vs full reconstruction limits – Any existing concrete pavement panel that is equal to or greater than 10 feet in width and within the proposed pavement limits shall be rubblized and add an 11-inch PCCP white-topping (amount of ABC to be determined). Full reconstruction shall occur on the approaches to approach slabs, the Inbound straightening, areas where geotechnical investigation determines the subgrade is inadequate and at tie-in points. Final design plans are to include a standard detail for the vertical transition from white-topping to full reconstruction.

c. Widened Gun Club Road bridges to accommodate phasing – The existing bridges over Gun Club include an 8-foot and a 6-foot shoulder, giving a total bridge width of 50 feet. In order to accomplish the phasing requirement of 3 lanes open at all times, a bridge width of 78 feet would be required across the bridge.

d. Widened Outbound Piccadilly Bridge by 12-15 feet – The existing outbound Piccadilly bridge needs to be widened in order to maintain 3 lanes at all times during construction.

e. Trail alignment (2-3 options) – DEN is in the process of studying a trail that connects the High Plains Trail to points east within Airport property. DEN is currently considering an option that runs parallel to the A line bridge and another option that sticks closer to Peña Boulevard. The goal is to minimize grading and structures required to pass over Third Creek.

f. Continuous accel/decel lane between inbound Gun Club On-ramp and Jackson Gap off-ramp – This will require some reconstruction along the existing ramp at Jackson Gap. The Consultant shall devise a design that minimizes reconstruction to and minimizes limited operations for the existing off ramp. The new configuration will include an off and a shared lane.

g. Inbound Gun Club off-ramp, including modified entrances to Development south of the new ramp.

h. Modified 75th/old Inbound Gun Club Road off-ramp to a 2-way surface street, including modified accesses to the development to the north.

i. Prepare conceptual designs and evaluate/analyze intersection types (signal, roundabout, other) for Gun Club Road/75th Avenue and Gun Club Road/New Inbound Off-ramp

2. West Approach Improvements (See Gun Club Ramps Conceptual Exhibit attached)

a. New Outbound off-ramps at Gun Club Road – Design two new outbound off-ramps at Gun Club Road. The first ramp is a standard Outbound Peña Boulevard off-ramp that ties into the eastern edge of Gun Club Road. The second Outbound off-ramp will tie into 78th Avenue west of Gun Club and shall create a new eastbound lane. These improvements will also require modifications to both Gun Club Road and 78th Avenue, as well as analysis at the new intersections and 2 new traffic signals.

The conceptual design will be analyzed by the project team and will be used to determine if all or some of the options will be carried forward. This conceptual design will also be used to start stakeholder coordination. The Consultant shall create a high-resolution pdf long plot (digital and hard copies) for this purpose.

3. Preliminary and Final Design The Consultant shall complete 30%, 60%, 90%, 100%, IFB and IFC submittals per DEN requirements.

As part of the preliminary design, the Consultant shall create a design criteria table that includes each roadway by name and all related design criteria. The table shall be submitted for review and approval.

The consultant shall perform all design criteria related calculations/analysis and submit them with the 60% design for review and approval. This includes but it not limited to vertical clearance, line of sight, turning templates and superelevation calculations.

4. Constructability Review DEN will conduct an industry constructability review based on corrected 30% plans. Anticipate pdf plan deliverable and attendance at industry review meetings. DEN will coordinate contractor meetings.

E. COST ESTIMATES AND FINANCIAL ANALYSIS

1. Preliminary Construction Cost Estimates The Consultant will prepare preliminary construction cost estimates based on the conceptual design.

2. Cost Estimates

All submittals will include Engineer’s Cost Estimates.

F. Water Quality

1. City of Denver MS4 Permit requirements WILL apply to this project. The Consultant will determine the requirements of the Municipal Separate Storm Sewer System (MS4), Colorado Discharge Permit System (CDPS), and design and permitting issues per the DEN PWQ Master Plan. It is anticipated that the total impervious area will be less than existing with the removal of the Toll Plaza pavement.

2. The Consultant will recommend and design appropriate Water Quality mitigation measures as necessary. Water Quality design shall be included starting with the 60% design and included through IFC.

3. The Consultant shall analyze the existing pond north of Peña Blvd at the Outbound Jackson Gap on-ramp tie in. Determine if the pond capacity is sufficient for the current and proposed impervious area and redesign the pond as needed.
