Home My WebLink AboutENG 01-21 Report to Executive Committee Report Number: ENG 01-21 Date: January 4, 2021 From: Richard Holborn Director, Engineering Services Subject: Municipal Bridge Maximum Gross Vehicle Weight Restrictions - By-law to establish a load limit for certain bridges under the jurisdiction of the City of Pickering - File: A-1440 Recommendation: 1. That the attached draft By-law limiting the gross vehicle weight of any vehicle or any class thereof, passing over certain bridges, under the jurisdiction of The Corporation of the City of Pickering be enacted; and, 2. That the appropriate officials of the City of Pickering be authorized to take the necessary actions as indicated in this report. Executive Summary: The Highway Traffic Act and Ontario Regulation 104/97 Standards for Bridges require that every bridge and/or structure be kept safe and in good repair through periodic inspections under the direction of a Professional Engineer and in accordance with the provisions of the Ontario Structure Inspection Manual, or equivalent. Further, The Highway Traffic Act establishes that municipalities having jurisdiction over a bridge may by by-law limit the gross vehicle weight of any vehicle or any class thereof passing over the bridge. The City of Pickering retains a qualified bridge inspection firm to perform regular bridge inspections every 2 years. In 2018, the City of Pickering retained Keystone Bridge Management Corporation to inspect and validate the gross vehicle weight limit restrictions for the bridge structures included in the parent by-law. Keystone Bridge Management Corporation conducted bridge load testing on 7 municipal bridges in support of determining the appropriate load limit for by-law purposes. As a result of the testing, load limits were assigned to the 7 bridges and established through By-law 7674/19 and accompanying Schedules A and B. Keystone Bridge Management Corporation was retained in 2020 to assess the City’s 71 bridges and culverts, of which 55 have a span of 3.0m or over. As a result of the recent assessments and inspections, 3 additional bridges require a load limit by-law and 1 bridge with an existing load limit by-law requires the load limit to be reduced, with a “Use at Own Risk” signage. Bridge #1002 on the Uxbridge Pickering Townline Road is currently being replaced, therefore a load limit will no longer be required. Based on the above, staff have prepared a proposed by-law which identifies the new recommended maximum weight load limits on 4 bridges (Bridge #7004, 8004, 8007 and 9003), ENG 01-21 January 4, 2021 Subject: Municipal Bridge Maximum Gross Vehicle Weight Restrictions By-law to establish a load limit for certain bridges under the jurisdiction of the City of Pickering Page 2 maintains the existing maximum weight load limits on 5 bridges (Bridge #6003, 7002, 8001, 8003, 9006), and repeals the previously established associated by-law By-law 7674/19. Financial Implications: The cost for Keystone Bridge Management Corporation to inspect and re-affirm proposed load limits at the 9 bridge locations and to certify the by-law was $4,725.00 plus HST which is being charged to 2290.2392.0000 Engineering Services – Administration. In order to remove the bridge load limits, future expenditures will be required to rectify structural deficiencies and to bring the bridges up to current code requirements. Discussion: In January of 2019, staff presented report ENG 01-19 to the Executive Committee. The report, as adopted by the Committee and approved by Council: • identified the maximum vehicle load limits established on 7 bridges as a result of the inspections on all bridges currently under the jurisdiction of the City of Pickering; • presented for Council endorsement, the draft by-law necessary for bridge load designations; and, • established the necessary schedules for signature by 2 Professional Engineers certifying the safe load limits and the duration for which the limits apply. As a result of the inspections undertaken by Keystone Bridge Management Corporation in 2020, there is a need to reduce the maximum vehicular weight limit restriction of Bridge #7004 (Sideline 34 - 0.2km south of Eighth Concession Road), from 10 tonnes to 5 tonnes which was the cautionary load limit as set out in Municipal Bridge Load By-law 7674/19. Three additional bridges: Bridge #8004 (Lot 20/21 Conc 8); Bridge #8007 (Lot 12/13 Conc 8); and Bridge #9003 (Lot 28/29 Conc 9) require a load limit by-law. Bridge #10002 on Uxbridge Pickering Townline Road 0.10 km east of Sideline 30 is currently under construction and no longer requires a load limit. The maximum vehicular weight limit restriction for the remaining 5 bridges remains the same as set out in the current by-law (By-law 7674/19). A copy of bridge site location maps, the draft amending by-law and revised Schedule “A”, which identifies all structures to which the by-law applies, are attached. If passed by Council, a completed Schedule “B” will be signed and sealed by 2 Professional Engineers from Keystone Bridge Management Corporation and will form part of the new by-law.
