Tracking close to or exceeding goals 7 CHALLENGES • Construction Schedule - Maintain it! Mitigate impacts • Central Core phasing - Complex; Minimize passenger and operational level of service impacts • Cobus Operations - Maximize level of service; minimize exposure to elements; maintain safety • Contractor Design Development estimate exceeds contractual allowance by $5.6M - 4 of 37 subs negotiated; Project Goal - stay within budget • Completing dining and retail projects on time - maintaining Phase 1A and 1B opening North Satellite - CHALLENGES 8 ACCOMPLISHMENTS • Met 2018 Project Q1 Goal - Primary structural steel installed for Phase 1 • Alaska level of service and passenger flow analysis completed for Concourse C to NSAT, preparing stakeholders for decision to transport passengers via Cobus to NSAT ground board positions during Phase 2 • 60% Alaska Airline Lounge Design & 30% Ground Board Design reviewed • Received Final Building Permit for the project on 1/16/18 • Received Passenger Loading Bridge installation and Casework bids • Completed Puget Sound Energy gas pipe work under east taxiway • Opened escalator NS4 in NSAT central core • Made decision to process passengers via Hardstand D to NSAT ground board gates via Cobus North Satellite - ACCOMPLISHMENTS 9 PROGRESS • Phase 1 Expansion floor slabs nearly complete, with roofing, interior concrete walls and site utilities ongoing. • Critical path central core escalator NS3 replacement just began • Alaska Lounge 90% design and coordination ongoing • Concourse C satellite transit station vertical circulation constructability review and redesign nearly complete • Expediting designs of Phase 1 dining and retail projects • Finalizing Cobus ground board design • East taxiway vehicle service road striping design being modified North Satellite - PROGRESS 10 SUSTAINABILITY Water Conservation • (2) 15,000 gallon tanks installed for rainwater capture from the roof. Piping system rough-in installation progressing ─ Anticipate 500,000 flushes annually by Low-flow fixtures each year Waste Reduction • 97% construction waste diverted from landfills: Copper wire, wood, steel, pipe, aluminum, plastic, concrete Progressing the steps toward the goals - Tracking LEED Silver Energy Conservation • Energy savings, 17% below code - Large scale LED lighting - Daylighting optimization and Lighting controllability - Insulation and glass - Baggage, Escalator, Elevator Motor Efficiency Status • Submitted to United States Green Building Council for 34 preliminary design review credits 11 View of the New Expansion from Concourse C 12 STS Level Progress 13 New Expansion STS level and Escalator core 14 River curtainwall construction underway 15 View of the New Expansion 16
