8f. Presentation - Concourse A Building Expansion for Lounges
Item No. 8f_supp Meeting Date April 27, 2021 Concourse A Building Expansion for Lounges To be constructed by Delta Air Lines Project Need and Drivers Lack of available space to accommodate a shift of lounge demand from South Satellite to Concourse A, for both Delta and the Port's shared use lounge Delta requested to design and construct a new facility using the Port's Tenant Reimbursement Agreement (TRA) policy Project is linked to both the opening of the International Arrival Facility and Airline Realignment Delta has requested approx. 25,000 square feet of lounge space Port's lounge demand is estimated to be ~12,000 square feet (have 4,850 square feet currently, with room to expand by an additional 1,500 square feet within existing building footprint) 2 Proposed Project Scope This approximately 47,000 SF expansion includes: - 24,500 SF for a new Delta passenger lounge, including 2,300 SF of shell space for future expansion - 7,600 SF of shell space for a future expansion of the neighboring Port of Seattle common-use lounge (of which only approximately 6,000 will be used) - 7,200 SF of vertical circulation, including stairs, elevators, mechanical space - 7,600 SF of support areas for mechanical, electrical, plumbing and fire protection systems The project also includes 1,200 SF of reconfigured existing space on the concourse level to accommodate a new lounge entrance and associated revisions to the adjoining restroom and Airport Dining and Retail space 3 Proposed Project Site location 4 Proposed Project Rendering Perspective Looking Towards Northwest 5 New Configuration Concourse Level Interior Concourse A Concourse Level Impacts: restroom and retail space 6 Project Estimate Design Phase $ 9.3 M Construction Phase $62.1 M Total Port Responsibility $71.4 M* *The estimate was developed by Delta Air Lines and will be updated after completion of 60% design documents 7 Cone of Certainty W e are here Risks Temporary impacts due to construction noise and disruptions Permanent impacts to adjacent spaces and operations Further expansion of the building envelope to provide additional leasable space would cost more and take longer Existing underground utilities may need to be relocated Existing utilities may need to be enlarged 9 Key Unresolved Scope Issues The project team is evaluating the impacts of expanding the building envelope to provide additional leasable space. The project as currently designed does not maximize the square footage available on the mezzanine level. The existing utilities providing ventilation air and hot and chilled water may not provide the capacity needed for this project and may need to be enlarged. 10 Project Request and Estimated Budget Requesting Commission authorize $6,180,000 of design funds Project estimate is $71,400,000 based on Delta's construction estimate (including Port soft costs) Current estimate does not include scope or budget for key unresolved scope issues Further design is needed to provide better scope, schedule and budget assurance Port and Delta will memorialize maximum project cost at 60% design milestone and will return to Commission to request construction authorization 11 Project Schedule 30% Design Completed Q1 2020 Commission Auth for Design Q2 2021 60% Design Completed (TRA Negotiation & Go/No-go decision) Q2 2021 AAAC Briefing for MII Vote Q3 2021 Commission Auth for Construction TRA Q4 2021 Construction Q1 2022 to Q2 2023 12 Next Steps Delta develop scope, schedule and budget impacts to key outstanding scope issues Port to make associated decisions on key outstanding scope Delta progress design to 60% Negotiation of 60% construction value and TRA Majority-in-Interest Vote with SEA Airlines Seek Commission authorization for construction based on 60% project estimate and split of costs is negotiated and accepted 13
