Dams and Water Management Engineering 21 August 2020 ANNEX A - TECHNICAL STATEMENT OF REQUIREMENTS Supply & Deliver New Stoplog Lifter for Rideau Falls West Dam Page 3 of 31 A1. SCOPE SUMMARY A1.1 Purpose This Technical Statement of Requirements (TSOR) defines characteristics required of a new stoplog lifter for Rideau Falls West Dam and associated requirements for equipment delivery. The new stoplog lifter will be used to remove stoplogs from sluices and stack them on dam deck; to retrieve stoplogs from stacked position and placing them in sluices; and, to move stoplogs between sluices along dam deck.

A1.2 Project Summary 1) Appoint a Project Manager to be responsible for Work and to be main point of contact with Canada. 2) Visit and inspect dam site and surrounding areas to conduct all necessary site inspections, surveys, measurements, evaluations, etc. In particular, locate dam appurtenances that could interfere with movements of stoplog lifters and verify all dimensions in situ and measure gauge and section of existing rails before finalizing size of stoplog lifters. 3) Design and fabricate new stoplog lifter. Design and fabrication must be supervised by Professional Engineer(s) licensed to practice in geographic area of fabrication. 4) Be available for site visits from Technical Authority to fabrication shop during fabrication period and before shipping. 5) Deliver, install, and set-to-work the new stoplog lifter on the dam deck. Installation must be supervised by a Professional Engineer licensed to practice in Ontario who must supervise installation and certify device to requirements of Ontario regulations, including doing a "Pre-Start Health and Safety Review" to O. Reg. 851. 6) Deliver spare parts, maintenance materials, special tools, and Operating & Maintenance Manuals. 7) New stoplog lifter must be delivered to the dam site no more than 40 weeks from contract Award.

A2. BACKGROUND A2.1 Rideau Falls West Dam The Rideau Falls Dam complex is located in the City of Ottawa where the Rideau River discharges into the Ottawa River over the Rideau Falls (see Figures 1, 2, and 3). The complex consists of the East Dam and the West Dam located respectively on the east and west sides of Green Island. The West Dam has four sluices (numbering shown in Figures 4 and 5). Sluices #2 and #3 use vertical lift gates to regulate water flow whilst sluices #1 and #4 use stoplogs. Stoplogs can also be placed upstream of the two vertical lift gates to allow the gates to be dewatered for maintenance. Stoplogs are wooden logs, rectangular in cross-section, stacked in special slots called "gains" in the piers (typical gain in Figure 14). The stacked stoplogs form a variable height weir, allowing more or less water to flow through the sluice depending on the number of logs in place in the gains.

A2.2 Stoplog Lifter Operations Stoplogs are handled with a stoplog lifter, being a crane customized to place stoplogs in the sluice and remove them from the sluices for storage on deck (old West stoplog lifter in Figure 8, current East stoplog lifter in Figure 19). The previous stoplog lifter, which was 25 years old, was found to be have a cracked structural member at its last inspection and has since been decommissioned. Canada requires a new stoplog lifting machine to replace the old one. Figures 10 and 11 shows the existing spreader beam, which is to be retained. This connects to a stoplog’s end caps through hooks located on lever arms (one at each end of the spreader beam). To hook onto stoplogs and to release them, Damkeepers move the lever arm manually, either doing this by hand for the upper stoplogs or Dams and Water Management Engineering 21 August 2020 ANNEX A - TECHNICAL STATEMENT OF REQUIREMENTS Supply & Deliver New Stoplog Lifter for Rideau Falls West Dam Page 4 of 31 by means of wooden poles when handling the lower stoplogs. The stoplog lifter lifts the spreader beam and stoplog together. The total load of a double stoplog with the spreader beam together is 7000 pounds weighed in air.

Mark centre of gravity on major subassemblies.

A4.1.2 Corrosion Considerations 1) All surfaces to be accessible for inspection and maintenance. 2) Design to eliminate water traps, avoid accumulation of water or dirt, and prevent corrosion. Provide drainage holes if necessary to meet this criterion. 3) Isolate dissimilar metals with nylon grommets, gaskets, or sleeves as appropriate. A4.1.3 Guarding and Safeguarding Employ inherently safe design measures, and where inherently safe design is not practicable, provide safeguarding such as (but not limited to) fixed guarding, interlocked guarding, etc. to CSA Z432 Safe Guarding of Machines and Canada Occupational Health and Safety Regulations (SOR/86-304).

A4.1.4 Personnel Tie-off Points 1) Provide four (4) engineered tie-offs for fall arrest equipment, located on underside of gantry over each gain, and another two (2) each located on each gantry for use by inspection and maintenance personnel climbing gantries. 2) Technical Authority will indicate preferred location on frame shop drawings when these are submitted as part of Preliminary Design Package.

Dams and Water Management Engineering 21 August 2020 ANNEX A - TECHNICAL STATEMENT OF REQUIREMENTS Supply & Deliver New Stoplog Lifter for Rideau Falls West Dam Page 6 of 31 A4.1.5 Flexible Horizontal Lifeline System 1) Provide two horizontal cables, one on each side of the sluice opening, so that two Damkeepers may tie-off and walk back and forth on deck beside stoplog lifter, one on upstream side and one on downstream side, for the full length of the stoplog lifter, (similar to that provided on the East Dam’s stoplog lifter.) 2) A Professional Engineer must design the system, including anchorages, according to good engineering practice. 3) Horizontal cable to: a) Section 85 of O. Reg. 851 Industrial Establishments, as amended; b) Section 12.10 of Canada Occupational Health and Safety Regulations (SOR/86-304); c) CSA Z259.16-15 Design of Active Fall-Protection Systems; and, d) CSA Z259.13 Flexible Horizontal Lifeline Systems. 4) Assume in design that, when using horizontal cable, Damkeepers are wearing a Class A full body harness to CAN/CSA Z259.10 Full Body Harnesses and a fall-limiting device to CAN/CSA Z259.2.2 Self-Retracting Devices for Personal Fall Arrest Systems complete with connecting components to CSA Z259.12-11 Connecting Components for Personal Fall Arrest Systems. 5) Note that this Standard specifies strength requirements for anchorages but not strength-testing requirements for such anchorages. Test strength of anchorages to provincial regulations, or submit calculations proving that they meet requirements.

A4.2 Gantry Structure A4.2.1 Configuration 1) Provide stoplog lifter with same general configuration as the existing stoplog lifter on the East Dam, that is, two gantry cranes rigidly joined together (see Figure 19 for general configuration). 2) Each gantry itself must consist of two portal frames joined at the top by a single transverse crane beam upon which the new underhung 5-ton wire rope hoist is to be mounted. 3) Each hoist will lift one end of the existing spreader beam. A4.2.2 Design 1) Design for a safe working load of 5,000 pounds per gantry (10,000 pounds for machine overall). 2) Dimensions a) Vertical distance from deck to underside of crane beam must be same as for previous version of stoplog lifter gantry (see Transcrane drawing). b) Gantry wheels to be located same as for previous gantry (see Transcrane drawing). c) Spacing between gantries must suit the lifting points on spreader beam (see drawing of spreader beam). d) Maintain minimum 3 inches clearance from all existing dam appurtenances in all positions on dam deck. 3) To make repairs and overhauling easier in future, use bolted connections in preference to welded wherever possible. 4) Clearly identify information about bolt strength and bolt torque limits on as-built drawings; this will assist in future when bolts are changed as part of periodic maintenance activities. 5) Provide rubber bumpers at ends of gantries to absorb kinetic energy of stoplog lifter impacting end stop on crane rail. 6) Rated Load Marking.—Mark stoplog lifter with maximum rated load, as per requirements of ASME B30.17 and Section 51 of O. Reg. 851 Industrial Establishments. Dams and Water Management Engineering 21 August 2020 ANNEX A - TECHNICAL STATEMENT OF REQUIREMENTS Supply & Deliver New Stoplog Lifter for Rideau Falls West Dam Page 7 of 31 A4.2.3 Shielding from Spray 1) Provide roof and walls over entire stoplog lifter to protect hoists from excessive ice build-up from spray in winter (see Figure 13 for typical winter conditions). 2) Roof must have positive slope for drainage to upstream and/or downstream sides of stoplog lifter. 3) Walls must extend down from roof to approximately 8 feet above deck level so as not to interfere with Damkeepers’ line-of-sight to water. 4) Design this shielding in small components weighing a maximum of 30 pounds, such that one man working from a boom truck can easily remove shielding and obtain access to hoists for maintenance purposes.

A4.2.4 Finish 1) Select coating system from one of the following three options: a) The Ontario Ministry of Transportation’s qualified products list #9.20.39 for Low VOC structural coatings (bridge paints) available online at http://applications.roadauthority.com/mpl/mpl.asp?MPIShortName=MTO+DSM; or, b) a proprietary coating, abrasion-resistant, designed so that ice does not adhere to it, with hardness and abrasion-resistant qualities no less than that of the bridge paints described above (submit test data proving this); or, c) powder-coating, abrasion-resistant, with hardness and abrasion-resistance qualities no less than that of the bridge paints described above (submit test data proving this). 2) Topcoat Colour a) High gloss black on gantry frame and outside of roof and walls b) White on underside of roof and walls to help reflect light onto dam deck 3) Colour of Primer and Intermediate Coats.—Any colour. 4) Surface Preparation.—To suit paint manufacturer’s requirements, but no less than SSPC-SP 10 Near-White Metal Blast Cleaning (NACE No. 2). 5) Film Thickness.—Maximum thicknesses that coating manufacturer allow for each product.

A4.3 Mechanical Systems A4.3.1 Hoists 1) In order to rationalize inventory of spare parts and maximize ability of one stoplog lifter to provide backups for the other, provide same make and model of hoists as on East Dam: a) Stahl model SH 4012-20 4/1 L2 KE with under-running trolley b) Capacity 5000 kg. c) Two lift speeds: 6m/min and 1 m/min. d) Two trolley speeds: 6.3m/min and 25m/min. e) Ingress protection: IP 66. f) Hoist modified by factory with 120V panel heaters fed on a separate circuit thus making hoists suitable for -40oC to +40oC operation. 2) Total lift distance same as previous stoplog lifter (see Transcrane drawing). 3) Lubricate wire rope when installing it on the drum. 4) Provide a third hoist that we will keep as a spare (ref. Section 6.4.5 of this TSOR).

Dams and Water Management Engineering 21 August 2020 ANNEX A - TECHNICAL STATEMENT OF REQUIREMENTS Supply & Deliver New Stoplog Lifter for Rideau Falls West Dam Page 8 of 31 5) Note: hoists are expected to be long lead-time items, estimated 14-20 weeks delivery. Schedule ordering accordingly. 6) Additional Overload Cut-Off.—Because lifting underwater, sometimes complicated by the presence of ice, does not allow Damkeepers to be certain of the load they are lifting, provide each hoists with an additional overload cut-off device set to 85% of the safe working load.

A4.3.2 Gantry Travel System 1) Use of Gantry Travel System a) The stoplog lifter is normally stored at Sluice #1 to minimize the stretch on the 600V power cable coming from the motorized cable reel. When Damkeepers need to move to other sluices to perform work, the gantry travel system will be used to move the stoplog lifter along the rails. b) The other stoplog-controlled sluice (Sluice #4) is at the other end of the dam, therefore Damkeepers frequently need the stoplog lifter to travel quickly from one end of the deck to the other (longitudinal dimensions given in Figure 5). Damkeepers will desire a higher speed of travel for efficiency in getting between the two sluices. c) Upon approach to the other sluice, Damkeepers will desire a lower speed travel in order to help line up the stoplog lifter with the sluice opening. d) To make precise positioning at the sluice, Damkeepers will perform inching/jogging motions with the gantry travel system in order to line-up the stoplog lifter with the sluice. They do this by eye based on their experience. e) Upon arrival at the new sluice, the gantry travel system will have a chance to cool off during the time the Damkeepers are manipulating stoplogs at the other sluice before the return trip to Sluice #1. The shortest time would be approximately 5 minutes, if the Damkeepers are only manipulating one stoplog. f) During their work, it could be the case that the Damkeepers will need to move the stoplog lifter slightly, about an inch or less, from one side to the other if they have difficulty hooking onto stoplogs. 2) Requirements for Gantry Travel System a) Use existing crane rails on dam deck. b) Provide driven power at both gantries, both drive systems being placed on the same side (either upstream or downstream). c) Locate all components of drive system such that they will be protected from impact from stoplogs when these are being stacked on deck. The configuration of locating the drive mechanism between back-to- back C-channels, similar to that of the East Dam’s stoplog lifter, would be one acceptable way of doing this, though there may well be others. d) Provide sheet metal cover over motor and associated components to protect them from spray, salt, etc. Cover must be removable for access to components for servicing. Cover must be strong enough to support weight of 300 lb. if a man ends up standing on it for any reason. e) Provide two-speed motor to achieve normal and low travel speeds. i) Normal travel speed: 3.81 m/min (12.5 ft/min) ii) Low travel speed: 1.14 m/min (3.75 ft/min) iii) Small variation in specified speeds (±15%) is permitted to account for exact motor rotation and standard gear sizes. f) System must operate at temperatures down to -40oC (ref. Section 4.4.2.2 of this TSOR). g) Gearmotors of gantry drive system and their starters must be capable of extensive inching/jogging action, in either direction of rotation, so that Damkeepers can achieve precise alignment of stoplog lifter with gains. Dams and Water Management Engineering 21 August 2020 ANNEX A - TECHNICAL STATEMENT OF REQUIREMENTS Supply & Deliver New Stoplog Lifter for Rideau Falls West Dam Page 9 of 31 h) Mechanical horsepower rating: service factor of 1.5 based upon maximum connected motor horsepower requirements. 3) Wheels.—Single flange type, mounted on roller bearings. Provide grease tubes for the bearings. 4) Braking.—Provide mechanical braking system at either wheels or axles to ensure positive stops and hold of gantry once Damkeeper has achieved correct position over sluice. Spring applied, solenoid released. Brakes must come on after a certain time delay to allow speed to drop to zero naturally―normal stop must be gradual. 5) Interlocks.—For motion along dam deck, provide mechanism to ensure that stoplog lifter has come to a complete stop before power can be applied through drive system to make it move in opposite direction.

A4.3.3 Lubrication 1) Provide grease tubes or otherwise ensure ease of access to lubrication points without having to dismantle anything more than simply removing a cover and while working from the dam deck. 2) Provide a numbered or lettered tag at each lubrication point corresponding to lubricant schedule and numbers on maintenance check-sheets. 3) Provide self-sealing grease fittings, identical in size, make, and model.

A4.3.4 Noise Level at Dam Deck Machinery noise when operating must be maximum of 87 dB(A) to meet exposure limits specified in Canada Labour Code, Regulation Part VII - Levels of Sound for continuous 8-hour operation.

A4.4 Electrical and Controls Systems A4.4.1 General Requirements 1) All materials and equipment to be CSA certified, and installed according to manufacturer’s instructions. 2) Controls must avoid fancy electronics in favour of simple, old-fashioned, devices. 3) Variable Frequency Drives (VFDs) are NOT PERMITTED.

A4.4.2.2 For Strip Heaters 1) Provide 120V power to the strip heaters that are within the control panels. This must be on separate circuit, which is itself fed from the 120V power on dam deck. 2) Because members of the public may be present on dam deck after hours, 120V supply to strip heaters must be configured as follows: a) Provide a manual cable reel located on deck, within in a lockable enclosure that has solid walls. b) Cable coming from manual cable reel must go up a 3-inch diameter pipe no less than 10 feet up from the dam deck to a 90-degree elbow directed towards the receptacle on the stoplog lifter when the stoplog lifter is parked at Sluice #1.

Dams and Water Management Engineering 21 August 2020 ANNEX A - TECHNICAL STATEMENT OF REQUIREMENTS Supply & Deliver New Stoplog Lifter for Rideau Falls West Dam Page 10 of 31 c) Provide a set of foldable or retractable steps on the frame of the stoplog lifter such that the Damkeepers can swing these into position, and go up a couple of steps to reach the receptacle and the cable from the manual cable reel, and in this way plug the cable into the receptacle. d) Provide sleeves and housings such that no water may enter the joint between cable and receptacle. e) Damkeepers will fold or retract steps into storage position after plugging-in the panel heater circuit and lock these in place so that members of the public cannot use them. f) Damkeepers will unplug this circuit before using stoplog lifter, and will plug it back in again after operations. g) Provide stopper ball on cable such that it cannot be pulled back down the pipe. h) Canada will provide the 120V circuit up to the location on the dam deck; the Contractor will install the cable reel and its vertical tube.

(2) Damkeepers turn the main disconnect ON, thus powering the stoplog lifter through the 600V power cable reel. ii) Damkeeper's pushbuttons activate solenoid to release the gantry brakes and start the gantry travel motors; the stoplog lifter travels from one sluice to another on the rails. iii) Provide high speed and low speed travel as described in Section 4.3.2 of this TSOR. c) Hoisting and Stoplog Transfer State i) Gantry travel motors are stopped, and spring-applied brakes keep the gantries from moving. ii) Hoists’ hoisting and trolley motors are activated by Damkeeper's pushbuttons to lift, lower, or move stoplogs between deck and sluice. iii) Hoists usually move together, but Damkeepers must have option to activate them separately if needed for precise stoplog positioning. d) Emergency Stop State.—Any one of the four emergency stop buttons can act as an OFF switch cuts all power to every motor on machine and all brakes come on with mechanical spring pressure allowing no use or movement.

A4.4.5 Lights 1) Use of Lights a) Damkeepers do most operations during the daytime, when lights are not needed. However, sometimes they do operations at dusk or in darkness. b) Provide Stoplog lifter with two sets of lights: c) “operating lights” (illuminating deck and down the sluice opening), and d) “headpond lights” (shining into headpond to allow Damkeepers to check for debris upstream before operating). 2) General Requirements for All Lights a) Ingress protection: IP 66 b) Impact protection: IK 10
