Total Project Cost: $4,470,000 Est. State and Local Taxes: $267,000 ACTION REQUESTED Request Commission authorization for the Chief Executive Ofcer to advertise and execute a single construction contract comprised of Aireld Apron Pavement Replacement (CIP #C102573) and NSAT-STS Ceiling Leak Long Term Repair (CIP #C800609). This authorization request is for $4,030,000 4,056,000, and the estimated total cost of the complete project is $4,470,000. SYNOPSIS Three projects, two CIPs and one expense project, are to be constructed on the aireld in 2014, and have been combined into a single construction contract in order to minimize disruption to the airlines and Airport patrons. The 2014 Aireld Improvement Project is part of an ongoing pavement management program to replace aged and distressed concrete pavement and joint sealant in nonrunway areas. The Runway 16C/34C panel replacement project will replace distressed concrete pavement panels to ensure the safe operation of the runway before the scheduled reconstruction of the Runway in 2015. Replacement of these panels will be paid for using $220,000 expense funds because they will not meet the longevity requirements for capitalization. NSAT-STS Ceiling Leak Long Term Repair will replace the failed concrete topping slab at gate N10 to prevent rain water from entering the NSAT above the STS lobby. COMMISSION AGENDA Tay Yoshitani, Chief Executive Ofcer March 19, 2014 Page 2 of 7 Both CIPs were included in the 2014 capital budget and plan of nance. The 2014 operating budget includes $160,000 for the Runway 16C/34C maintenance. BACKGROUND The Port has replaced distressed concrete pavement panels and joint sealant on the aireld as part of an ongoing aireld pavement program. Concrete pavement panels and joint sealant typically have respective design lives of 20 and 10 years. Currently, there is a signicant amount of aireld pavement and joint sealant that have far exceeded their expected service lives. Concrete debris resulting from the deteriorating pavement can become a hazard for aircraft and personnel. The replacement of the distressed panels is necessary for the safe operation of aircraft. The replacement ofjoint sealant reduces water intrusion and helps to extend the life of I pavements. The 2014 Aireld Improvement Project will replace twelve deteriorated panels located near the North Satellite. Eleven panels are currently identied for replacement on Runway l6C/34C. Expense funds will be used for the replacement of panels on Runway 16C/34C, due to its planned reconstruction in 2015. Pavement joint seal will be replaced on portions of Taxiway B and Taxilane W that are located west of the South Satellite. The NSAT-STS Ceiling Leak Long Term Repair project will eliminate ceiling leaks at the NSAT that occur between the STS and the elevators. Rainwater currently inltrates through the severely cracked topping slab. The existing waterproong membrane between the topping slab and underlying structural slab is now over 40 years old and has exceeded its service life. There is also inadequate drainage to keep water from ponding on the slab. The combination of the cracked slab, inadequate drainage, and non-functional water-proong membrane allows water to enter the interior of the NSAT at the STS lobby. Ceiling leaks create risk in an area with a high amount of passenger trafc that contains electrical and mechanical equipment, such as escalators. The timing of the project is critical to limit exposure of the interior of the STS lobby to weather while exterior components are being replaced. The estimated total project cost includes $300,000 previously authorized for design of 2014 Aireld Improvement Project and $220,000 for design of the NSAT-STS Ceiling Leak Long Term Repair. The Commission previously authorized use of a project labor agreement for both projects. PROJECT JUSTIFICATION AND DETAILS Project Objectives: 0 Provide structurally sound pavements for current and future customers. 0 Provide reliable and appropriatesized infrastructure systems. 0 Minimize total lifecycle cost (capital and expense). 0 Minimize operational impacts. COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer March 19, 2014 Page 3 of 7 Scope of Work: This request includes the following elements: Apron panel replacement of approximately twelve panels. Runway panel replacement (for RW 16C/34C) of approximately eleven panels. Replace joint seal on portions of Taxiway B and Taxilane W. Replace failed pavement and waterproong membrane and construct drainage facilities at Gate N10 of the North Satellite.

Budget Status and Source ofFunds Both CIPs are included in the 2014 2018 capital budget and plan of nance. The RW 16C/34C expense work was included in the 2014 operating budget for $160,000. The Airport will seek to absorb the increase through savings or use of contingency. The funding sources for these projects include the Airport Development Fund and future bonds. The Port plans to issue bonds in 2014 to fund a number of projects. FinancialAnalysis and Summary Renewal/Enhancement Renewal & Replacement N/A N/A $4,470,000 Aireld Movement Area and Aireld Apron Area NOI after depreciation will increase N/A CPE Impact $.01 in 2014 due to expense work, $.02 in 2015 and beyond due to capital costs. Lifecycle Cost and Savings The replacement of concrete panels and joint seal will result in cost avoidance for maintaining them. Geometric constraints limit the depth of the pavement that can be constructed at the North Satellite and may reduce the life of those particular concrete panels. The elimination of rainfall intrusion into the North Satellite will minimize the risk of damage and associated cost to components within the building. The reconstruction ofj oint sealant between existing concrete panels helps to extend the life of pavements, which will reduce the long-term, lifecycle cost. STRATEGIES AND OBJECTIVES This project supports the Port's Century Agenda objective of meeting the region's air transportation needs at Seattle-Tacoma International Airport for the next 25 years. Ensuring safe COMMISSION AGENDA Tay Yoshitani, Chief Executive Ofcer March 19, 2014 Page 5 of 7 and secure operations and managing assets to minimize the long-term total cost of ownership assist in meeting this objective. TRIPLE BOTTOM LINE Economic Development Generally, there are no economic impacts related to renewal/enhancement projects since they are primarily related to preservation of existing business activity. Environmental Responsibility The project contains appropriate environmental controls to prevent sediments from entering stormwater systems. Removed concrete panels are anticipated to be crushed and recycled as has occurred on previous, similar projects. Community Benets Maintaining runway and aireld apron pavement benets both our airline customers and travelers. ALTERNATIVES AND IMPLICATIONS CONSIDERED 1) Do nothing: This alternative would result in an increasing risk of aircraft ingesting concrete debris into aircraft engines from distressed pavement, adversely affecting Airport operations and allow water from rainfall to continue to leak through the North Satellite ceiling. This is not the recommended alternative. 2) Replace the deteriorated and aged pavement panels and joint sealant on runway and non- runway areas during the 2014 construction season. This allows for the programmatic replacement of aged and distressed pavement and joint sealant and addresses the North Satellite ceiling leaks. This is the recommended alternative.
