Task 1 —Load Rating for Specified Bridges <br /> The services in this task include utilization of the existing load ratings, as-built plans, and <br /> inventory inspection data to perfoiin Load Factor Ratings (LFR)per current WSDOT and <br /> FHWA guidelines. All rating activates will include ratings for Specialized Hauling Vehicles <br /> (SHV) and for Emergency Vehicle (EV) as required by the FHWA's Memorandum on Load <br /> Rating of Specialized Hauling Vehicles (SHV) dated November 15, 2013 and Emergency <br /> Vehicles (EV)per FHWA Memorandum dated November 3, 2016. TranTech will provide the <br /> actual single unit rating for the SU4—SU7 vehicles regardless of whether the Notional Rating <br /> (screening) Load (NRL) check is greater than 1.0. <br /> The Load Rating Reports will consist of: <br /> • A Bridge Rating Summary Sheet reflecting the lowest rating factor, including <br /> superstructure components. The summary sheet shall be stamped and signed by a <br /> professional engineer licensed in the State of Washington. <br /> • A brief report of any potential anomalies in the ratings and an explanation of the cause of <br /> any rating factor less than 1.0, including site specific proposed load posting that will <br /> cause the least disruption to City of Lake Stevens residents and the traveling public. <br /> • A hard copy of computer output files used for rating, and any other calculations or special <br /> analysis required. <br /> • A complete set of plans for the bridge if they exist. <br /> • A CD which contains the final versions of all input and output files, and other <br /> calculations created in performing the load rating. <br /> • All reports shall be bound in Accopress-type binders. <br /> A paper copy of generated reports will be prepared and submitted to the City for inclusion in the <br /> Official Bridge File. <br /> Quality Assurance Program is an integral part of our work plan. It includes the following: <br /> • Competent and experienced personnel will perform all calculations. <br /> • The load rating will be thoroughly reviewed and checked by experienced personnel prior <br /> to submittal. <br /> • Any rating factor less than 1.0 will receive additional scrutiny to ensure load restrictions <br /> are avoided if possible. <br /> As mentioned above, should load posting become necessary, TranTech will work with the City <br /> to determine the best valid posting solution to cause the least impact to the traveling public. <br /> The City of Everett Engineering On-call Services Page 2 <br /> TRANTECH ENGINEERING <br />
