The scope of work describes two tasks that have been identified in the original scope of work v 9.0 as optional services: Construction Management Development of Signal Timing Plans Task 7: Development of Signal Timing Plans The Siemens ITS team will develop AM, PM, midday, weekend and Peak Holiday Synchro models for the 25 Tukwila Urban Center intersections listed in Table 1. Synchro will be used to develop an optimum cycle length and time -based signal coordination plans (AM, PM, midday) for each intersection within the study area. The Synchro model will be built based upon aerial orthophotos and data collected from field reviews. This task will include the following sub tasks: Task 7.1: Synchro Model Coding and Calibration Existing City furnished signal timing data and the existing City Synchro model will be used to build the new Synchro models for the project area. Once the models are complete, the Consultant Team will compare the simulations from the Synchro models to observed field conditions. If any significant differences exist, the Consultant Team will calibrate the Synchro model to be consistent with observed conditions. This calibration will include checking the arrival of platoons, the volume -to- capacity ratio, saturation flow rates and the existing queue lengths. Deliverables Calibrated AM, Midday, PM, Weekend and Holiday Peak Synchro model covering all intersections in the study area. Task 7.2: Develop Coordinated Signal Timing Plans The Synchro models will be used to evaluate cycle lengths, phase splits, offsets, band width, delay, traffic congestion and potential traffic management alternatives. 24 hour counts will be collected in the project area to determine the schedule for the new time of day plans. Deliverables Recommendations for cycle lengths. AM, Midday, PM, Weekend and Peak Holiday coordinated timing plans in electronic Synchro 6.0 format Recommendations for time-of -day periods to implement the coordinated plans. Task 7.3: Implementation and Fine Tuning Once the Synchro model development is complete, the Consultant Team will confirm that the proposed timings are providing the expected results in the field through field fine tuning. This task shall include the following activities: Convert Synchro output to SEPAC local software input. Enter SEPAC coordinated timings into the ACTRA central signal system for each intersection. Siemens ITS Page 2 SIEMENS Observe the signal performance in the field during all peak periods as the new timings are implemented. Identify and implement changes to offsets and splits, if necessary, to improve performance. Update Synchro files with field changes. The Consultant Team will utilize Tukwila's CCTV cameras on the corridor to support the effort of field fine tuning the coordinated signal timings. The field fine tuning involves driving the primary comdors in the field, and observing traffic flow from the side of the street to determine if vehicle platoons arrive at the appropriate time and if side street and minor movement phases receive an adequate amount of green time. Assumptions: The Consultant Team shall be provided access to the central signal system and CCTV cameras starting as early as 6:OOAM and ending as late as 6:30PM on weekdays and from 10AM to 6PM on weekends the days fine tuning is performed and for collection of saturation flow rate data. Deliverables: Electronic signal timing files (Synchro 6.0 format) for AM, Midday, PM, Weekend and Peak Holiday periods including any changes made during field fine tuning. Completed signal timing forms showing all new signal timing data for study area intersections. Task 7.4: Before Travel Time Surveys The Consultant Team will perform floating car studies before the new signal timings are implemented to set the baseline to later evaluate the improved performance of the signal timings on the corridors in the Tukwila Urban Center. The before floating car studies will evaluate the total travel time, total number of stops and delay per intersection. Five to eight travel time runs will be performed in each direction on up to four corridors in the study area. All runs will be performed during the peak two hours of the AM, Midday, PM, Weekend and Peak Holiday timing periods. The results of the before study will be summarized in a report. Deliverables: Electronic copy of before data and the compiled before results. Task 7.5: Data Collection The following elements will be included in the data collection task: The Consultant Team will supervise the collection of traffic counts. It is assumed that traffic counts will be performed for a maximum of 4 periods per intersection, at the 25 intersections listed in Table 1. The actual collection of traffic counts is not not included in this task it is assumed that the collection of traffic counts will be performed outside of this contract. Field work necessary to allow for the Data Collection task will be completed as part of the construction integration contract. This includes the connection of the system detectors at the cabinets, and their setup in the traffic controllers. Field work performed under this task will include the following: Siemens ITS Page 3 SIEMENS Verifying channelization, lane widths and pocket lengths Verifying phasing and signal operations provided by the City Collection of saturation flow rates at up to five intersections in the study area. Evaluate other factors that would impact signal timing such as parking, bus stops, tum restrictions and lane imbalances. Budget The budget for Task 7 is $73,038.

Task 8: On -Call Construction Support Services The Siemens ITS Team will provide post design construction support services on an as- needed basis. It will work together with the construction contractor to facilitate the construction activities. Such support may include assistance in preparing bid addendums, bid review, inspection assistance for specialty equipment, and assisting in preparing responses to contractor request for change or clarification, coordination with other entities for Right -of -Way as needed. Site visits to review facilities will be made if necessary Support will include cooperation with Westem Systems as requested during the provision and integration of the ACTRA system. It should be noted that this task assumes a limited number of hours of support. If the budget for Task 8 is exhausted, the Siemens ITS Team and the City of Tukwila will agree whether additional construction support services are needed and negotiate a new budget accordingly Deliverables Construction assistance as needed within constraints of allocated budget.

Jim Morrow, Director of Public Works; Frank Marie, Deputy Director; Bob Giberson, Acting City Engineer; Cyndy Knighton, Senior Engineer; Diane Jenkins, Administrative Assistant to the Council, and Chuck Parris, Community Member Business Agenda A. Tukwila Urban Center (TUC\ Signal Interconnect and ITS Bid Award Mr Morrow reminded the committee of the gridlock that took place in the Tukwila Urban Center (TUC) after the 2001 Nisqually Earthquake, when businesses' employees, customers, and other visitors to the city all attempted to leave the area simultaneously. This caused difficulty for emergency and maintenance personnel as they tried to respond to situations. The TUC Signal Interconnect project will connect 32 traffic signals. It was noted that some of the signals are not under City control (e.g., West Valley Highway, Grady Way) and that interlocal agreements will need to be entered into with the controlling agencies. All of the traffic signals will be sent back to an operation center to be controlled. In addition, there are other programming options available such as having the ability to connect private security systems. Ms. Knighton noted that there were cost savings on this bid because conduit was installed throughout the TUC as other projects were being completed and because the City will provide some of the equipment and services. She reviewed the map of signal placements and connections. Ms. Hernandez asked when the project would be completed. Ms. Knighton replied that construction has 140 days after notice to proceed is given. Some additional traffic counts are needed and a plan developed for how the signals should be connected. This plan should be implemented during the 1 or 2 quarter of next year Mr Morrow noted that this year, seven signal poles were hit by motorists; many of whom did not have automobile insurance. Replacement of these poles cost the City approximately 530,000. Three of the seven poles knocked down had video cameras on them. Unanimous Approval. Move to Committee of the Whole for discussion then to Regular Council for approval. B. Tukwila Urban Center Signal Interconnect and ITS Full -Time Construction Management Services Supplemental Agreement (Jacobs Civil. lnc.\ Supplemental Agreement No. 2 has been nego with Jacobs Civil, Inc., to provide full -time construction management and inspection services on the Tukwila Urban Center (TUC) signal interconnect and ITS project, not to exceed $170,863. Mr Morrow noted that the amount listed in the recommendation was incorrect and should be $170,863, not 5107,863. Unanimous approval. Move to Committee of the Whole for discussion then to Regular Council for approval. C. Tukwila Urban Center Signal interconnect and ITS Part-time On -Call Construction Support Services (Siemens ITS Ai Supplemental Agreement No. 1 has been negotiated with Siemens ITS for part -time on-can construction support services on the TUC Signal Interconnect and ITS project for a fixed fee not to exceed 593,325. Ms. Carter noted that this system is very adaptive and will be a great resource to make adjustments based on criteria such as the time of day and holidays. Mr Morrow concurred that the system wilt be monitored by a transportation operations technician, and adjusted as appropriate. Each signal will have 8 hours of backup power Unanimous approval. Move to Committee of the Whole for discussion then to Regular Council for approval. New Business Mr !date noted that there wilt be a public meeting at the Tukwila Community Center on Thursday, September 14, 6:30 p.m., to discuss the Bow Lake Renovation Project. Ms. Carter asked that the date of this project be publicized so residents are prepared. She also requested that plans be made so that the coupons given to residents during the annual spring clean -up are accepted by other transfer stations.
