L1C 3K6 �•d,� �:;?ki4 rte=" 416/263-8871 August 21, 1986 f1�� Town of Newcastle 40 Temperance Bowmanville, Ontario L1C 3A6 Attention: Lou-Ann Birkett Purchasing Agent RE: SNOW-MELTING SYSTEM BOWMANVILLE FIRE STATION Dear Lou-Ann, The following is a quotation for the replacement of the / present electric snow-melting system with a hot water system. I have been inst�dl.ing the hot water system for the past nine years and it has proven itself to be very reliable and -trouble fret system. � Instead of electric cables being buried in concrete, 3/4" high density polyethylene pipes are run on 9" centres up and down the ramp. They are fed with a 2" supply line to the top and the water is collected at the bottom in a 2" return line . The ,/ pipe, Dupont "Sclairpipe" , is quite flexi,ole, accommodaf,'ting ground movement easily as well as expansion and coptraction of the concrete . Being polye- thylene plastic ' t does not corrode as would metal. pipes and is nearly identical to the gas piping that is used to oring service to/ one ' s home . It is also rated at series #160 which is 8 times the normal. operating pressure and is not affected by most liquids i .e salts and acids . (cont ' d. f� 3 , (a) . . ./2 Each joint is heat welded together at 2500 C. so once the system is installed the joints will not come apart. In order to heat the water I met with Mr. Tony Galloway of Superior Plumbing & Heating. The present boiler does not have enough additional capacity to heat the ramp and the building both. Consequently, we are recommending an additional gas boiler be installed in the boiler room to supply only the ramp heating system. I have included prices for both a standard unit and a high efficiency unit. Based on figures supplied by Consumer Gas, the operating cost for a standard boiler are 28% less than for an electric system, and the high efficiency boiler is 46% less than an electric ,oiler. In addition, the hot water system includes 2 thermostats that will supply the heat only upon demand. The following is a proposal of work to be done : TLaff7bvA L. A. �— ; of existing concrete slab only at bottom and at top of slab (approximately 15 feet either end) to maintain present entrance slope and street grade . B. Installation of Dupont polyethylene piping as per attached specifications) 6X6X#6 welded wire mesh over piping to reduce concrete cracking. C. Installation of boiler and connection to gas supply, ramp supply and ramp return lines . Install thermostatic controls . D. Test system at 40psi for leak detection. E. Pour 5-6" concrete slab over piping. Concrete will be 30 MPA, class A exposure rating, designed for truck traffic . F. Fill with 50 : 50 mixture of glycol-water and start up system. Price . a) Ra;np replacement, concrete and piping only $10, 500.00 b) Installation of Standard Boiler & Thermostat 4, 500.00 c) Installation of High Efficiency Boiler 8, 000.00 (cont ' d. . ./3 ) . . ./3 Guarantee: We will provide a guarantee on the ramp for a period of 5 years provided it is operated in accordance to specification. I recognize that my quotation is higher than your present quote for replacement of the electric system. However, I feel that because of the greater reliability, efficiency, and the reduced operating costs of the hot water system it should be very seriously considered. Even though I have an oovious personal interest in seeing a not water system installed, I frankly feel it is a much better system. If you wish references as to its merits or to my a.pilities as an installer I will be harpy to provide them. Having said all the above, I did contact an installer of electric ramps, Sandy Smith of Mountsberg Electric . Sandy and I have shared clients who have both systems and my sources indicate that he is a reputable tradesman. We met on the ramp last Thursday night and I am passing along his comments to you. Sandy told me that it appears that the electric service to*111ramp is not sufficient . Based upon Pyrotechnic ' s requirement, the supplier of the cable, the ramp require' 44 , 000 watts/per hour minimum. Sandy could only find a supply of 25, 000 watts . I suggest you check with your present quote to see if this is a problem. If you are persuaded to retain the electric heating system you may negotiate with him directly. His phone number is 416/659-7309 . In conclusion, thank you for your consideration. Should there be any clarification, question or representation required, please do not hesitate to contact me .

Remove corroded steel pipe . Clean and patch base slab . 4 . 2 Partial. breakout of concrete surface slab at either or both ends may be all that is required on existing ramps that are long enough and gentle enough in slope . Such procedure should be brought to the owners attention for approval . 5. 0 Fabricating Polyethylene Piping Network 5. 1 General : Joining .polyethyl.ene pipe is precise but rapid and gives joints that are as strong as the pipe itself . An electrically heated joining tool melts a thin layer on the inside of the coupling and the outside of the end of the pipe . The molten surfaces are joined and left to cool resulting in a strong integral joint . Heating times are guide- lines for ideal conditions . Field personnel_ may have to extend heating times due to weather conditions . In case of high winds , the tool should be shielded in an insulated container to prevent; excessive heat lost . /.3 5 . 2 Socket fusion procedure to 2 " , 3" and 4" polyethy- lene pipe and fittings. - Chamfer pipe ends to aid in centering. - Use depth gauge and cold ring to ensure proper socket penetration and alignment . - Check to see that heating tool temperature is about 265 degrees C . ( 500 degrees F. ) - Time or count out heating cycle '( 25 seconds duration) once fitting and pipe are in place on tool . - Snap tool straight out of fitting and off pipe . - Line up pipe and fitting carefully when ,joining parts together and hold in place for 25 seconds . 5. 3 Saddle fusion procedure for 2 " , 3" and 4" polyethy- lene pipe and fittings. - Support the pipe to maintain straightness during the fusion. - Place saddle fitting on tool and pre-heat for about 15 seconds then place tool and saddle squarely on main applying about 60 to 80 lbs . of force for a period of 50 seconds . - Snap off saddle from tool. and place squarely to melt pattern on main and hold for about 25 seconds . - Drill_ out hole through saddle outlet before proceeding. 5. 4 Make tip collector and return headers using proper pipe size and fuse saddles on the main at 9" on centres for the required width of the area to be heated . 5 . 5 Socket fuse pre-measured lengths of cont-inous 3/4" Polyethylene pipe between headers ( 10 sec . heat ) . 5 . 6 Tie in collector and return 11c!aders Co supply piping using flanges .

In some cases this may take one or two hours . 8 . 4 Turn on heater and allow to heat up to normal operation temperature . Check pressure during heating up time to make sure it does not exceed 30 psi . Bleed off if necessary . 9 . 0 Normal Operating Pressure and Temperature 9 . 1 Normal operating pressure is between 10-15 psig at normal operating temperature . 9 . 2 Normal operating temperature is 120 degrees F. and the supply line shall be thermostatically controlled not to exceed this limit . 10 . 0 Final Inspection 10 . 1 Check out all pumps, valves and gauges for operating efficiency. 10 . 2 Check out concrete surface for possible cold spots or unusual conditions . i Lill 0 ATTACHMENT "B" � . KREMCO LIMITED 4 - "Electronic Fault Location" ' I R t 149 Hamilton Street ,ry Toronto,Ontario M4M 2C9 Telephone: (416) 482-0806 July 7 , 1986 Town of Newcastle Fire Department 132 Church Street Bowmanville, Ontario L1C 1T5 Attention: Mr . J.A. Aldridge Dear Sir : The following is a price quotation to replace the electric snow melting cables in the underground entrance ramp at fire hall at 132 Church Street. KREMCO proposes the following: 1) To prepare the ramp surface prior to laying the first coat of mastic asphalt. (proposed size 29 X 44 feet) 2) To provide a 1 inch deep key at the top and bottom of the ramp to minimize grade changes and help anchor the mastic asphalt. 3) To lay a base coat (approx 3/8" thick) of mastic asphalt. 4) To install three new Pyrotenax heating cables to cover an area of 1188 square feet, at a power loading of 22.8 watts per square foot with an average cable spacing of 7 . 5 inches. This cable layout would leave an unheated width of 1 foot 0 inches on each side of the ramp. This power loading will match the existing system that is now installed. 5) To cover the heating cables with a layer of expanded steel mesh reinforced mastic (approx 1/2" thick) , then apply a road wearing surface (approx 3/4" thick) . 6) To connect the cables to the existing power supply and controls . 7 ) To clean up the work site and remove all debris. 8 ) To supply all labour and materials . 9) To warrant the operation of the heating cables for a period of three years from the date of installation. Should the cable(s) fail during this period Kremco shall repair or replace the cable(s) at our option. HEATING CABLES AND MASTIC 11960 .00 cont. . . .
