Home My WebLink AboutENG 02-23 Report to Executive Committee Report Number: ENG 02-23 Date: March 6, 2023 From: Richard Holborn Director, Engineering Services Subject: Municipal Bridge Maximum Gross Vehicle Weight Restrictions -By-law to establish load limits 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: 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, section 123 (2) of the Highway Traffic Act, R.S.O. 1990 C.H. 8, as amended, establishes that municipalities having jurisdiction over a bridge may, through 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 and to recommend gross vehicle weight limit restrictions every two years. In 2022, the City of Pickering retained Keystone Bridge Management Corporation to review, inspect and assess the City’s 29 bridges and 27 culverts, all of which have a span of 3.0m or over. Keystone Bridge Management Corporation also conducted detailed load testing on nine municipal bridges in support of determining the appropriate load limit for by-law purposes, Bridge #9006 was omitted from the testing process, however the previous load limit will remain. As a result of the recent assessments and inspections, one additional bridge requires a load limit by-law and one bridge is recommended to have the load limit increased. Based on the above, staff have prepared a proposed by-law which identifies the new recommended maximum gross vehicle weight load limits on two bridges (Bridge #6004 and #7004). The by-law will maintain the existing maximum gross vehicle weight load limits on the remaining eight bridges (Bridge #6003, #7002, #8001, #8003, #8004, #8007, #9003, #9006), and replaces the previously established associated By-law 7807/21. ENG 02-23 March 6, 2023 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 Financial Implications: The cost for Keystone Bridge Management Corporation to review, inspect, assess and recommend proposed load limits at the ten bridge locations, and to certify the by-law was $4,394.80 plus HST which is being charged to the Current Budget, Engineering Services – Admin, Cost Centre 10500, GL 502230. In order to remove the bridge load limits, future expenditures in the Capital Budget will be required to rectify structural deficiencies and to bring the bridges up to current code requirements. Discussion: In January of 2021, staff presented report ENG 01-21 to the Executive Committee. The report, as adopted by the Committee and approved by Council: • identified the maximum gross vehicle weight load limits established on nine 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 limits; and, • established the necessary schedules for signature by two Professional Engineers certifying the safe load limits and the duration for which the load limits apply. As a result of the inspections undertaken by Keystone Bridge Management Corporation in 2022, the following table indicates the 10 Bridges with the recommended maximum gross vehicle weight restrictions in tonnes: Bridge ID 2022 Recommended Posting (tonnes) Notes 6003 15 Previously posted at 15 tonnes 6004 20 Newly added in 2022 7002 15 Previously posted at 15 tonnes 7004 10 Previously posted at 5 tonnes. Detailed Load testing (in 2022) has increased Structure capacity at 10 tonnes 8001 15 Previously posted at 15 tonnes 8003 20 Previously posted at 20 tonnes 8004 20 Previously posted at 20 tonnes 8007 20 Previously posted at 20 tonnes 9003 20 Previously posted at 20 tonnes 9006 10 Previously posted at 10 tonnes ENG 02-23 March 6, 2023 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 3 Bridge #7004 (Hoover Bridge), has been re-assessed and the load limit has been increased from 5 tonnes to 10 tonnes. Currently the bridge serves two residences (4440 and 4445 on Sideline 34). The revised load limit will mean emergency services can provide better response to the area. One additional bridge, #6004 (Sideline 32); will be added to the updated load limit by-law restricting loads to 20 tonnes. The maximum gross vehicle weight restrictions for the remaining eight bridges (Bridge #6003, #7002, #8001, #8003, #8004, #8007, #9003 and #9006) remains the same as set out in the previous By-law 7807/21. A copy of bridge site location maps, the draft by-law and a 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 two Professional Engineers from Keystone Bridge Management Corporation and will form part of the new by-law.
