,Mr.Bruce Westby,PE n December 16,2016 Page 3 Analysis Upon completion of the field review, SEH will compile crash history information for the most recent S years of available data(through the City and County and also through the State of Minnesota's crash website). SEH has already performed an updated AM and PM peak hour traffic count(7-9 am and 4-6 pm)at the intersection as part of nearby flashing yellow arrow analysis for the County and will use this information in order to determine current traffic patterns and peak hour intersection usage. Using existing signal plans,site review information,and data compiled for this intersection, SEH will perform a brief but detailed analysis of the signal system to determine which movements are able to be upgraded to flashing yellow arrow operations. A preliminary cost estimate will also be prepared for the City to determine estimated costs to upgrade the individual signal system to have flashing yellow arrow operations. Equipment required to be upgraded will be briefly listed for City information and consideration. A letter report will be prepared for City(and County)review and consideration that will include: • Analysis of traffic counts to determine potential time of day implementation of flashing yellow arrow operations, • Work recommended to be completed at this intersection, ■ Limitations on implementation of flashing yellow arrow operations, • Overall intersection estimated costs to upgrade to flashing yellow arrow operations, Final FYA Design As part of this analysis,no final design services for signal modifications are included in the proposed scope of work. If requested, SEH can provide the City with estimated design and construction administration costs for construction of FYA improvements for City consideration and budgeting. SEH can also provide the City with a separate proposal which would include all design,bidding,and construction observation services needed to fully implement the construction of these improvements. Schedule SEH proposes to begin work after a Notice-To-Proceed is issued by the City. We will complete a field review of the intersection in January--February 2017 and provide the City and County with our analysis findings by March 1,2017. Compensation The proposed work program includes a detailed field review of the signal system,analysis and report preparation. We propose to be paid for the work we do on an hourly basis based on direct labor costs,plus the actual cost of reimbursable expenses. The field review,intersection analysis,and report preparation work,as defined above,will be done on an hourly basis(plus reimbursable expenses)for a cost-not-to-exceed of$1,700. These costs will not be exceeded except as otherwise approved by the City. Any additional tasks added to or deleted from this project(due to significant changes in the general scope of the project or its design including,but not limited to,changes in size,complexity of character or type of construction) shall be by written amendment to the contract signed by both parties.
