BACKGROUND The Washington State Department of Transportation (WSDOT) approved Major Maintenance funding for 3 Tukwila Bridges in December 2014 and funding acceptance was approved by Council in February 2015. DEA was contracted for the design in July 2015 for all three bridges; Grady Way Bridge, Beacon Ave S Bridge and the Frank Zepp (S 180th St) Bridge. The original scope and fee were based on the best information available at the time. DISCUSSION Site investigations of the Frank Zepp Bridge have revealed unanticipated settlement and pier movement. Correction of these issues requires additional site survey and design work. This supplement also adjusts the project schedule and corrects some technical statements listed in the original scope. A safety concern was noted on the trail beneath the west end of the Frank Zepp Bridge, which will not be covered by federal funds, but can be completed at a savings under this contract. FINANCIAL IMPACT City Projects 91510406, 91510407, and 91510408 are included in Contract No. 15-139. Only the fee for the Frank Zepp Bridge is increasing in Supplemental Agreement No. 1. The federal funding requires a 10% agency match. The City match will increase by $4,829.70 and the trail lighting design will cost $5,489.00, to be paid from the 2015 Bridge Inspection Program.

The three bridges were identified as good candidates for federal funding under the Local Agency Bridge Program administered by WSDOT. The proposed work will preserve the City owned infrastructure and extend the service lives of the bridges. Federal grant funding was approved December 2014. Council budget amendment approved 8/3/15. MAINT. IMPACT: Maintenance needs will be reduced once these three major maintenance projects are completed. The three bridges were approved for grants under separate federal aid numbers but will be combined into one COMMENT: for the design & construction contract. Grant funding requires a 10% match for the design phase; projects that obtain construction authorization by 9/30/18 are eligible for 100% Federal funding for construction.

(CONSULTANT) entered into a professional services agreement on July 23rd, 2015 with for development of bridge repairs and construction contract documents for the following: 08561400 TUKWILA -02 FRANK ZEPP BRIDGE 07996800 TUKWILA -13 BEACON AVENUE BRIDGE 08543600 TUKWILA -08 GRADY WAY BRIDGE During the design development, a number of items were discovered that were not anticipated during the initial scoping. They include: • Settlement of the roadway in the vicinity of Pier 1 of the Frank Zepp Bridge. This settlement is potentially attributed to combined seismic and vehicular induced settlements. To counter this settlement, design and construction of a west approach slab is recommended for two reasons: to provide a transition from the hard bridge surface to a softer soil supported roadway facility to the west, and to provide seismic resistance benefits, including friction resistance to longitudinal bridge movements. • Pier 2 of the Frank Zepp Bridge has a slight tilt toward the Green River channel. It is thought that this tilt is caused by additional lateral forces induced by the trail running underneath the Span 1 of the bridge. Additional engineering analysis and assessment is recommended to study the information provided by the surveying activities and geotechnical investigations regarding the Pier 2 condition. • The trail running underneath Span 1 of the bridge is not lit. This task will provide design for installation of lighting on the bridge deck soffit and on top of the trail to ensure a lit and safe trail for the trail users. The following Scope of Services (SCOPE) describes the work to be performed for this Supplement (Supplement #1). TASK 3.0 FRANK ZEPP BRIDGE MAINTENANCE 3.02.S1 Structural Analysis Bullet Point 1 in original Scope of Services is amended to read: • Seismic Analysis: CONSULTANT shall use the seismic design criteria developed to perform seismic analysis and determine required capacity to strengthen bridge to achicvc Level 1 Life using sound engineering judgment and experience to meet the requirements of the Performance Level 0 (PLO) criteria. 3.02.02.S1 Geotechnical Pier Isolation Recommendations CONSULTANT shall prepare pier isolation recommendations at Pier 2 relative to the trail loading on the pier. Pier isolation concepts may include removal and replacement of the existing earth fill with lightweight materials such as expanded polystyrene (geofoam) or pier wall jacketing. Recommendations will be prepared for design and construction of the preferred isolation concept and included in the final geotechnical report for the project. Assumptions: City of Tukwila 1 Scope of Services, Supplement 1 Major Maintenance on Three Bridges November 17, 2015 21 1. No field explorations or laboratory testing of soils will be performed. The recommendations for pier isolation will be developed using existing information and simplified, conservative design assumptions. Attendance at not more than one design team meeting at DEA's Bellevue office is assumed. Deliverables: 1. Draft design and construction recommendations for Pier 2 isolation will be transmitted to the design team in electronic format with the final recommendations incorporated in the final geotechnical report deliverable. 3.03.01.51 West Approach Slab Design and PS &E CONSULTANT shall prepare concept and final designs, construction plans, engineer's estimate, and special provisions (PS &E) for the installation of an approach slab on the west approach to the FRANK ZEPP BRIDGE. This slab task is recommended for seismic enhancement of the west abutment and its immediate vicinity. Currently the abutment and its vicinity is experiencing settlement. This task involves creating two structural sheets that show a plan view and structural details of this slab and its connection to the west abutment. CONSULTANT shall prepare 90% and 100% AD Ready Plans, Specifications, & construction Opinion of Cost Estimates (PS &E) for this task. The PS &E for this task will be incorporated into the Project PS &E deliverables. Current City of Tukwila Infrastructure Design and Construction Standards shall be followed throughout the design process. Deliverables: 1. 90% and 100% AD Ready PS &E documents for the West Approach Slab 3.03.02.S1 Additional Engineering Assessment CONSULTANT shall review any additional survey and geotechnical data required for the seismic assessment and retrofit design of the Frank Zepp Bridge per Level 0 (PLO) Performance criteria. The geotechnical data pertains to the assessment of the effects of the installed trail adjacent to Pier 2 of the Frank Zepp Bridge and its associated lateral pressures on the pier. 3.03.03.S1 Under -deck Trail Lighting Design and PS &E CONSULTANT shall prepare concept and final designs, construction plans, engineer's estimate, and special provisions (PS &E) for the installation of under deck lighting over the trail under the west end of the Frank Zepp Bridge. The installation of lighting will conform to vandal resistant fixtures lighting the pathway to 1.0 FC and 4:1 uniformity with fixtures having low maintenance, high efficiency, and a wavelength of between 4,000 and 4,300 wave length. An illumination report will represent the design. The power source will be either the existing signal installation at Sperry Avenue and S 180`h Street or an alternate source selected by the AGENCY. Lighting will remain on at all hours unless otherwise directed. Deliverables: City of Tukwila 2 Scope of Services, Supplement 1 Major Maintenance on Three Bridges November 17, 2015 22 1. 90% and 100% AD Ready PS &E documents for under -deck lighting. 3.08.S1 Survey During recent site visits, CONSULTANT staff determined that Pier 2 is not plumb. This could be due settlement at and around Pier 1 as a result of recent seismic activity or additional loads created by installation of the trail under Span 1. In order to investigate these observations in further detail and compare measured elevations with the as -built information, a survey is recommended. CONSULTANT shall survey bridge to determine current elevations and geometry, and compare these to as -built conditions to determine if bridge has settled, shifted, or rotated. Deliverables: 1. One plan sheet showing elevations and planar coordinates for as -built condition, current condition, and table listing the changes. TASK 5.0 GRADY WAY BRIDGE MAINTENANCE 5.02.S1 Structural Analysis Bullet Point 1 is amended to read: • Seismic Analysis: CONSULTANT shall use the seismic design criteria developed to perform seismic analysis and determine required capacity to strengthen Piers 2, 3, 10 and 11to-,16.14eve using sound engineering judgment and experience that meets the requirements of the Performance Level 0 (PLO) criteria.
