RECOMMENDATION: It is respectfully recommended: 1. That this report be received; and, 2. That the 1983 funds budgeted for the rehabilitation of the Graham Creek (Hate's) Bridge be reallocated to a project for rehabilitation of the Jackman Road Bailey Bridge in Bowmanville. 11141421111114 Funds have been provided in the 1983 Budget for rehabilitation of the Graham Creek (Hate's) Bridge in former Clarke Township. Over the years, through grading of the road, gravel has been deposited on the bridge deck to a considerable depth. Also, the concrete railings have deteriorated and are in need of repair. In 1982, an appraisal of the bridge was performed with the recommendation that the road grade in the vicinity of the ...2 6 0' `' _. `, f� > � I Vp?R, ifj [} J Page 2 REPORT: WD -80 -83 (Ca-J bridge be lowered so that the gravel could be removed from the deck and that concrete repairs be made. Estimated costs for such work are in the order of $40,000. In the meantime, there has been considerable discussion over the ultimate status of a private solid waste disposal site in the area, which in turn leads to some uncertainty of the status of roads in the vicinity. It could well be that if the waste disposal site is expanded, the Town could be in the position of having the developer upgrade the surrounding roads. Accordingly, it would seem prudent to wait for some decision on the ultimate status of the site prior to scheduling remedial work to any of the Town roads in the area. The conditions at the bridge, while undesirable, do not place it in immediate structural jeopardy and can be postponed for a short time. With respect to reallocation of the funds budgeted for this work, it is recommended that they be used to rehabilitate the Jackman Road Bailey Bridge in Bowmanville which is presently structurally deficient and has load restrictions. Some of the structural steel members have corroded to the point where they cannot carry the loads for which the bridge is designed. The attached report on this matter provides further detail with respect to physical condition and costs. The bailey bridge is on loan to the Town from the Ministry of Transportation and Communications and as pointed out previously is deteriorating to the point where its structural integrity may cause failure. ...3 Page 3 REPORT: WD -80 -83 Furthermore, the following are pertinent facts: 1. The ultimate location of Jackman Road is a long range plan and will probably not materialize within the ten year time frame. Accordingly, the existing bridge will be in use for some time. 2. The Town, having borrowed the bridge from the Province, would seem to have some moral obligation to maintain it in good repair. 3. Repairs would be subsidized by the M.T.C. at a rate of 80 percent. Costs associated with the repairs would be in the order of $40,000, the same amount budgeted for the Graham Creek Bridge. Considering the pertinent facts in this matter, it is recommended that the funds previously budgeted for rehabilitation of the Graham Creek Bridge be reallocated to rehabilitate and repair the Jackman Road Bailey Bridge.

DUPUIS, P. ENG., DIRECTOR TEL. (416) 263.2231 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: 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 justified. - 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 i 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. 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. .i - 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 1• •i 11 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.

Site 21 -91 RLCEIVE L) JAN 2 6 tc'� lw one. oo Date: 8 3. 01 . 2 4 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 the main problems are the sway braces, the transoms and the stringers. This structure was probably composed of older material and was presumably painted rather than being galvanized. For this reason, the deterioration has taken place in a Short period of time. The material cost to refurbish the bridge has :increased suhstantially but this is due to the yising cost of nnaLerials. After consultation. with our Central Stores, th(2 Cost for new material would be as follows : P buttons stringers 0 239.61 - 2875.32 13 plain stringers 0 200.00 - 3600.00 14 Std. wide Transoms 0 920.79 - 12891.06 12 Std. wile sway braces @ 16S. S2 - _1_986.24 21352.62 this, I appreciate, is twice the cost given in the field on January 19th. 1 have been informed by Franck 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 S tonnes. f, ' y` "m, To: Mi-.

Wide with 1 -10' Ramp) Site 21 -91, Bownanville Date: 1983 Ol 20 On January 19, 1933 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 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. Bec,iu, e of the precarious condition of the bridge deck systein the trd I f is load should be decreased to 5 tons and speed limit reduced to 10 km /hr. maximum. FR:ac cc: E.
