ENG., DIRECTOR HAMPTON,ONTARIO TEL.(416)263-2231 LOB 1J0 987-5039 REPORT TO THE GENERAL PURPOSE AND ADMINISTRATION COMMITTEE MEETING OF FEBRUARY 21 , 1983. REPORT NO. : WD-14-83 SUBJECT: JACKMAN ROAD BAILEY BRIDGE RECOMMENDATION: It is respectfully recommended: i 1. That this report be received; and, 2. That the Director of Public Works be authorized to proceed with the repair and restoration of the Jackman Road Bailey Bridge; and, 3. That the cost of repair and restoration be charged to Bridge and Culvert Maintenance, Account Number 7206-X-00402-X. BACKGROUND: Following a major structural failure in the spring of 1970, the Town of Bowmanville retained Procter and Redfern, Consulting Engineers, to prepare a report on the replacement of the Jackman Road Bridge. The report summarized that with the proposed improvements of Regional Road 57 west of Bowmanville Creek the importance of the Jackman Road Bridge would diminish and therefore the reconstruction of the Bridge to a two lane width in its present location was not r justified. �4 � 2 _ An immediate requirement for a crossing to provide access to the Bowmanville Landfill Site was recognized and a temporary Bailey Bridge was erected at the site. The Ministry of Transportation and Communications loaned the Bailey Bridge to the Town for a period of two to three years in order to allow the Town time to access the development in the area. This loan arrangement has now been extended to October, 1983. In 1975 preliminary cost estimates of $96,000. were quoted to replace the single lane structure in its present location utilizing the existing bridge abuttments and approaches. The cost for the same work today would be in excess of $200,000. i In June of 1982, the Public Works Department received a copy of the Annual Bailey Bridge Inspection Report prepared by the Ministry of Transportation and Communications. While in the process of completing the recommended maintenance contained in this report, Town Staff noted that the stringers supporting the deck planking were badly corroded and would not support full loads. The M.T.C. structural office notified of our concerns, completed a further inspection on January 19, 1983. As a result of the precarious condition of the bridge deck system, Town Staff have signed the road with "NO HEAVY TRUCKS" signs and posted maximum load limit signs of five (5) tonnes. 3 REPORT: The estimated cost of repairing and restoring the bridge structure is as follows: Replacement Structural Material Costs M.T.C. $21,352.62 Town Labour & Equipment 15,000.00 36,352,62 10% Contingencies 3,635.00 39,987.00 Approximate Cost: $40,000.00 If the existing transoms are found to be salvageable, the estimated cost of repair will be reduced to $25,000.00. In the 1982 Five Year Capital Forecast, an amount of $20,000. was proposed for a preliminary bridge design and preparation of a property acquisition plan. This project is now advanced in the Capital Forecast to 1984. The eventual realignment of Jackman Road and construction of a new bridge over Bowmanville Creek will eliminate the need to maintain this structure in its present location. It is proposed that Jackman Road west of Scugog Street will terminate in a cul-de-sac on the east side of the creek. Respectfully submitted, R.G. Dupuis, P.

Osborn Date: 83. 01 . 24 District Municipal Engineer District 6 , Toronto From: Structural Office 3501 Dufferin Street Downsview, Ontario Re : Town of Newcastle JQ ^-,,-44e-1 Rd. , Bailey Bridge M. T. C. Site 21-91 A phone call from the Town, initiated the inspection , which was carried out by Frank Romano , who is quite conversant with bailey bridges . You will note from the attached report that themain problems are the 'sway braces , the transoms and the stringers . This structure was probably composed of older material and was presumably painted rather than beirig. galvanized. For this reason, the deterioration has taken place in a short period of time . The material cost to refurbish the bridge has increased substantially but this is due to the rising cost of materials . After consultation with our Central Stores , the cost for new material would be as follows : 12 button stringers @ 239 . 61 - 2875 . 32 18 plain stringers @ 200 . 00 - 3600 . 00 14 Std. wide Transoms @ 920 . 79 - 12891 . 06 12 Std. wide sway braces @ 165 . 52 - 1986 . 24 21.352 . 62 this , I appreciate , is twice the cost given in the 'field on January 19th. I have been informed by Frank Romano that the transoms could be salvaged by the Town and with sandblasting and painting , the transoms would be satisfactory. This would reduce the material cost to approximately $8500 . Since the bailey bridge is still the property of the M. T . C . , a problem could arise over the replacement of the bailey components . I recommend that consideration be given to a new bridge at this site or closure of the road. The present bailey could remain in limited service for several years provided it is posted at 5 tonnes . V i V memorandum Ontario To: Mr. K. Kleinsteiber Date: 1 .983 01 20 Head Approvals Section Re: Jackman Rd. Bailey Bridge (60' D-•S Std. Wide with 1-10' Ramp) Site 21 -91 , Bowmanville On January 19, 1983 the writer (accompanied by Messrs. Ron Dupius, Director of Public Works; David T. Gray, Deputy Director of Public Works and foreman Ellwood Hawes) visited the above site to assess the condition of the Bailey bridge. i I found the stringers to be very badly rusted , several being completely rusted through web and flanges. Transoms and sway braces are also exhibiting a fair amount of rust. Trusses and other components are in good condition and they have . been painted recently with the exception of the bottom of the .-bottom-chord of all -trusses. My recommendations are: - Replace all sway braces, transoms and stringers . - Remove surface rust from bottom of bottom chords of trusses and repaint. Because of the precarious condition of the bridge deck system the traffic load should be decreased to 5 tons and speed limit reduced to 10 km/hr. maximum.
