PORT OF SEATTLE MEMORANDUM COMMISSION AGENDA Item No. 4b ACTION ITEM Date of Meeting November 11, 2014 DATE: November 3, 2014 TO: Ted J. Fick, Chief Executive Officer FROM: Michael Ehl, Director, Airport Operations Wayne Grotheer, Director, Aviation Project Management Group SUBJECT: 2015 Airfield Pavement Replacement Program (CIP #C102573) Amount of This Request: $200,000 Source of Funds: Airport Development Fund and Future Revenue Bonds Est. State and Local Taxes: TBD Est. Total Project Cost: $ 1,761,000 ACTION REQUESTED Request Commission authorization for the Chief Executive Officer to 1) design, prepare construction documents, and implement temporary measures as necessary to replace distressed pavement and joint sealant for the 2015 Airfield Pavement Replacement Program at Seattle- Tacoma International Airport (Sea-Tac) in the amount of $200,000 and 2) for the utilization of a project labor agreement (PLA) for this project. The total estimated project cost is $1,761,000. SYNOPSIS This project is part of an ongoing Pavement Management and Maintenance Program (PMMP) as required by the FAA. The PMMP includes replacing aged and distressed pavement and joint sealant in non-runway areas. Many sections of airfield pavement have exceeded their 20-year service life and have become cracked and damaged. The PMMP is necessary for safe and efficient aircraft operations. Replacing damaged pavement on the airfield supports the long-term strategy of the Port's Century Agenda objective to "Meet the region's air transportation needs at Seattle-Tacoma International Airport for the next 25 years." This project is included in the 2015 2019 capital budget. BACKGROUND The 2015 Airfield Pavement Replacement Program is a continuation of the programmatic approach of replacing distressed concrete pavement panels and joint sealant as part of a multiyear program. Template revised May 30, 2013. COMMISSION AGENDA Ted J. Fick, Chief Executive Officer November 3, 2014 Page 2 of 6 It is estimated, based on historic panel distress levels that approximately 12 panels on the airfield, in random locations, will need to be replaced by 2015. Work will also include joint sealing taxiway B and taxilane W, between taxiways N and Q. Depending upon where pavement panels are replaced, it may be necessary to design and implement temporary measures, to mitigate airline impacts due to aircraft gate closures. Closure of gates can occur if distressed pavement panels are found near gates, which may cause reassignment of domestic and international flights to alternate gates. Port staff will return to the Commission to request additional funding in the event that extensive temporary modifications for reassigning gates and parking areas are required that exceed the authorized funds. The current budget for CIP C102573 is $24,602,213. The funds utilized through the end of the 2014 construction season are expected to be $22,841,213. The current estimate for the 2015 Airfield Pavement Replacement Program is $1,761,000. This project may also be bundled with other 2015 Airfield Improvement Projects (AIP) to increase efficiencies between AIP contracts. This would be addressed when Port staff returns to Commission for Construction Authorization. Maintaining critical airfield assets supports the Port's Century Agenda objective to meet the region's air transportation needs at Seattle-Tacoma International Airport for the next 25 years. The PMMP maintains the integrity of airfield pavements and efficient airport operations. Deferring panel and joint sealant replacement could potentially increase risk to airfield operations and drive costs higher in the future. Project Labor Agreements have been used on past airfield projects in order to reduce risk to operations caused by work interruptions. Staff recommends that this project utilize a project labor agreement. PROJECT JUSTIFICATION AND DETAILS Project Objectives Replace aged pavement and joint sealant as part of the PMMP Provide stable pavement conditions Support the Port's Century Agenda Scope of Work Produce final design for the apron pavement. The design will include utilities, temporary striping and lighting and other scope items related to the project. COMMISSION AGENDA Ted J.

Lifecycle Cost and Savings Annual Operating and Maintenance costs are not anticipated to change appreciably. The replacement of concrete panels will result in cost avoidance for maintaining them. STRATEGIES AND OBJECTIVES Maintaining critical airfield assets supports the Port's Century Agenda objective to "Meet the region's air transportation needs at Seattle-Tacoma International Airport for the next 25 years". TRIPLE BOTTOM LINE Economic Development This project furthers the Airport's business plan objectives to operate a world-class international airport by ensuring safe and secure operations and by managing our assets to minimize the total long-term cost of ownership. Environmental Responsibility During repair and maintenance activities, various sustainable practices will be considered and implemented when practicable. Community Benefits Increasing safe operations at Seattle-Tacoma International Airport allows the community and local business owners to prosper from the jobs and passengers the airport generates. ALTERNATIVES AND IMPLICATIONS CONSIDERED 1) Do nothing: This alternative would result in an increased risk to airfield operations as pavement failures occur and an increased risk to airfield safety from concrete debris resulting from distressed pavement. This is not the recommended alternative. 2) Replace distressed pavement and joint seal on the airfield during the 2015 construction season. This allows for the programmatic replacement of aged and distressed pavement as well as replacement of joint seal. This is the recommended alternative. COMMISSION AGENDA Ted J.
