Widen Arrivals Roadways
COMMISSION AGENDA MEMORANDUM Item No. 10a ACTION ITEM Date of Meeting March 14, 2023 DATE : March 7, 2023 TO: Stephen P. Metruck, Executive Director FROM: Laurel Dunphy, Director Airport Operations Eileen Francisco, Director Aviation Project Management Group SUBJECT: Widen Arrivals Roadways (CIP #C800866) Amount of this request: $73,600,000 Total estimated project cost: $89,500,000 ACTION REQUESTED Request Commission authorization for the Executive Director to (1) advertise and award up to three major public works contracts; (2) execute utility agreements for the relocation of utilities; (3) transfer $527,000 of budget from C800862 Terminal Security Enhancements to support the installation of security bollards; (4) transfer up to $3,860,000 of budget from C801042 Landside Pavement Program to support additional pavement rehabilitation, and (5) and authorize an additional $73,600,000 for a total project authorization of $89,500,000 for the Widen Arrivals Roadways project at Seattle-Tacoma International Airport. EXECUTIVE SUMMARY This authorization supports the construction of the Widen Arrivals Roadways project that provides the necessary roadway capacity for Airport parking and ground transportation operations. This project will be delivered through multiple design-bid-build construction contracts and supported by the separate procurement of long lead items and multiple utility relocation agreements. The overall project cost has increased from $79,100,000 to $89,500,000 due to higher than anticipated escalation, additional costs due to project phasing and coordination requirements, enhanced landscaping requirements, and additional scope increases. Additional airline majority-in-interest approval is not required for this project. This project will also install the final security bollards as originally envisioned as part of the Terminal Security Enhancements project, and complete pavement rehabilitation scope envisioned as part of the Landside Pavement Program project. JUSTIFICATION This project supports the following Century Agenda strategic goals and objectives: Template revised January 10, 2019. COMMISSION AGENDA – Action Item No. 10a Page 2 of 7 Meeting Date: March 14, 2023 1) Advance this region as a leading tourism destination and business gateway by meeting the region’s air transportation needs by delivering vital facilities and infrastructure in a sustainable and cost-effective manner. 2) Be the greenest and most energy efficient Port in North America by meeting or exceeding agency requirements for storm water leaving Port-owned or operated facilities. 3) Be a model for equity, diversity, and inclusion by increasing utilization of Women and Minority Business Enterprise (WMBE) and Disadvantage Business Enterprise (DBE) DBE firms and eliminate disparity of access to opportunities. The terminal roadway system was originally designed in 1968 to support an overall activity level of 25 million annual passengers (MAP). Over the years several efforts have been completed to extend the life of the terminal roadway system. These include relocating commercial ground transportation services to the third floor Ground Transportation Center and Northeast Ground Transportation Lot, extending the Arrivals curbside to the south for public transit and commercial ground transportation, and relocating rental car customers off-site to the consolidated Rental Car Facility. Approximately 45.9 million passengers used the airport in 2022, and Arrivals experienced recurring congestion at peak travel times daily. Widening of roadways accessing Arrivals and the Main Garage will improve access to parking, ground transportation center, and curbsides by alleviating congestion and reducing queuing on the main roadway entrances for airport visitors and passengers. The project will enhance roadway safety to accommodate the existing passenger activity. With no improvements, studies have indicated that the queueing on the Northern Airport Expressway will reach the I-5/I-405 South Center interchange on a regular basis during the summer months. Diversity in Contracting There will be a 9% federally certified Disadvantaged Business Enterprises (DBE) requirement for the Widen Arrivals Roadway contract. The project team will work with diversity and contacting on the goal for the separate major works contracts. DETAILS The Widen Arrivals Roadways project includes the widening of the southbound lanes of the Northern Airport Expressway to provide an additional two lanes for a total of six lanes from South 170th Street into the Departures and Arrivals curbsides and Main Garage. This requires the relocation and expansion of the roadways to the west given the location of the columns supporting the Light Rail Transit guideway. In addition to the improvements described above, the project will relocate the north rental car transit curb further north to increase utilization of the Arrivals curbside. The scope of work for this project has increased to include additional utility relocations and the renewal of utility infrastructure impacted by the project. As an enabling action the project has already completed the demolition of the fourth-floor bridge from Template revised June 27, 2019 (Diversity in Contracting). COMMISSION AGENDA – Action Item No. 10a Page 3 of 7 Meeting Date: March 14, 2023 Departures to the Main Garage that was closed with the construction of the light rail transit walkway. On June 14, 2021, the Port of Seattle issued a determination of non-significance for the Widen Arrivals Roadways project. A State Environmental Policy Act (SEPA) checklist was completed and was the basis for that determination. The budget for Widen Arrivals Roadways has increased from $79.1M to $89.5M predominantly due to four factors: 1) $5.0M for additional costs associated with project phasing and coordination including storm water management; 2) $2.9M for higher than anticipated cost escalation for electrical equipment, traffic control labor, and fuel; 3) $1.9M increased landscaping costs to reflect the Landscape Master Plan vision; and 4) $1.1M for additional scope changes including cameras to support operations, the removal of abandoned industrial wastewater system infrastructure, and an alignment shift supporting operations during future roadway construction. The project will be delivered through four design-bid-build major works contracts. The first contract is complete and included the early demolition of the fourth-floor bridge between Departures and the Main Garage. The second contract will complete the roadway realignment, lane additions, and utility system infrastructure improvements and will utilize a project labor agreement. The second contract will also be supported by multiple utility relocation agreements, and potentially the procurement of long lead items. Staff is currently evaluating the risks associated with owner procurement for these items. The third contract will construct the transit canopy for rental car transit operations. The fourth contract would provide additional landscaping in areas that would be impacted by the future Sustainable Airport Master Plan (SAMP) Near-Term Projects. This fourth contract may or may not be implemented depending upon the implementation of the SAMP Near-Term Projects. Art is planned to be incorporated within this project in two areas. The first is the airfield retaining wall visible from the Northern Airport Expressway, portions of the Main Garage, and the Light Rail Transit station. The second is within the north rental car transit stop which will be visible from the Arrivals curbside, portions of the Main Garage, and by rental car customers. Scope of Work The Widen Arrivals Roadway project is a roadway improvement project. These types of projects generally include paving, sidewalks, barriers/curbs, pavement markings, illumination, storm drainage, retaining walls, signage, sign structures, safety elements (e.g., attenuators), and Intelligent Transportation Systems (ITS) improvements. As part of the improvements to the north rental car transit curb this project will install the remaining security bollards at the north end of the Arrivals curbside. These were originally included with the Terminal Security Enhancements project, but this request will transfer that Template revised June 27, 2019 (Diversity in Contracting). COMMISSION AGENDA – Action Item No. 10a Page 4 of 7 Meeting Date: March 14, 2023 scope and budget to this project to complete. This reduces the overall costs to the Port since rework will be avoided. This project will also complete additional pavement rehabilitation scope on Air Cargo Road and the southbound lanes of the Northern Airport Expressway. This work was originally envisioned as part of the Landside Pavement Program, but this request will transfer that scope and budget to this project to complete. The Widen Arrivals Roadways project was completing pavement rehabilitation scope on those same roadways so combining these efforts reduces the overall costs to the Port.
