2.4 GRANULAR BASE

.1 Granular base requirements shall be in accordance with Division 2.



2.5 PAVER TREATMENT

.1 Provide paver surface treatment in accordance with Section 03300. 3 Execution 3.1 SITE PREPARATION

.1 The site must be stripped of all topsoil, unstable or unconsolidated materials to the grades indicated.

.2 All subdrainage or underground services within the pavement area must be completed

in conjunction with subgrade preparation and before the commencement of base construction.

3.2 VERIFICATION OF SUBGRADE

.1 Construction will not proceed until the subgrade has been inspected and approved by the Consultant.

3.3 VERIFICATION OF GRANULAR BASE

.1 Place graded aggregate for base over compacted subgrade. Provide compacted thickness of base as indicated. Compacted base will be 100% of maximum density achieved in accordance with ASTM D698 (100% Standard Protector maximum dry density) unless indicated otherwise in Geotechnical Report.

.2 Base is to be spread in layers which, when compacted, will not exceed 100 mm.

.3 Profile of base to be within an allowable local tolerance of 12 mm within 3 m.

.4 The upper surface of the base is to be sufficiently well graded and compacted to prevent

infiltration of the bedding sand into the base both during construction and throughout its service life. Segregated areas of the granular base will be “blinded” by the application of crushed fines which have been watered and compacted into the surface.

.5 Further construction will not proceed until the base has been inspected and approved by

the Consultant. 3.4 GRANULAR BASE THICKNESS

.1 Provide a granular base to a depth shown on drawings. 3.5 SURFACE DRAINAGE

.1 Gradients and crossfalls are to have a minimum value of 1% and are to be channelled to appropriate drains away from any unrestrained edge.



3.6 SAND BEDDING COURSE

.1 Spreading: The bedding sand is to be spread loose in a uniform layer to give a depth after compaction of the paving units, of between nominally 30 mm to 35 mm. Under no circumstances will the bedding layer exceed 40 mm in thickness following compaction of the pavement.

.2 Screeding: The spread sand will be carefully maintained in a loose condition and

protected against precompaction by traffic or rain both prior to and following screeding. Sand is to be lightly screeded in a loose condition to predetermined depth. Under no circumstances is the sand to be screeded in advance of the laying face to an extent to which paving will not be completed on that day. Any screeded sand which is precompacted prior to laying of paving unit will be brought back to profile in a loose condition. Neither pedestrian nor vehicular traffic will be permitted on the screeded land.

Screed bedding sand using either an approved mechanical spreader (e.g. an asphalt paver) or by the use of screed guides and boards.

3.7 INSTALLATION OF PAVERS

.1 Pavers with excessive chips, cracks, voids, discolourations or other defects are not to be installed.

.2 Pattern: Lay clay pavers in running bond and all other pavers in pattern as indicated on

drawings.

.3 Colour Blending: Paving units are to be installed from a minimum of 3 bundles simultaneously drawing the paver vertically rather than horizontally.

.4 Joints: In order to maintain the desired patter joint spacing must be consistent. For

maximum interlock, it is recommended that a joint spacing of approximately 2 mm to 3 mm be maintained. This spacing must also be provided for the first row abutting the edge restraint. Under no circumstances shall the joint exceed 3 mm.

.5 Alignment: String lines or chalk lines on bedding sand are to be used to hold all pattern

lines true.

.6 Cutting: The gaps at the edge of the paving surface are to be filled with manufactured edge pavers or with pavers cut to fit. Cutting will be accomplished to leave a clean edge to the traffic surface using a mechanical hydraulic or guillotine cutter or masonry saw.

.7 Sweeping Clean: Upon completion of cutting, the area must be swept clean of all debris

to facilitate inspection and to ensure pavers are not damaged during compaction.

.8 Inspection of Installed Pavers: After sweeping and prior to compaction, the paved area must be inspected to ensure satisfactory colour blending. Pavers can be moved easily at this time to achieve good colour distribution.



3.8 INITIAL COMPACTION OF PAVERS

.1 After inspection of the paving units, they are to be compacted to achieve consolidation of the sand bedding and brought to design levels and profiles by not less than three passes of suitable compactor as recommended by paver manufacturer.

.2 Initial compaction should proceed as closely as possible following installation of the

paving units and prior to acceptance of any traffic or application of sweeping sand.

.3 Compaction should not be attempted within 1 metre of the laying edge. 3.9 PAVER INSPECTION

.1 Any units which are structurally damaged during compaction will be immediately removed and replaced.

3.10 STANDARD JOINTING SAND

.1 The jointing sand is to be spread over the pavement after initial compaction has been completed. This jointing sand is to be spread as soon as is practical after initial compaction and prior to the termination of work on that day.

.2 The jointing sand is to be broomed to fill the joints. Excess sand will then be removed

from the pavement surface and the pavers are to be compacted again to settle the jointing sand.

3.11 POLYMER JOINTING SAND

.1 The jointing sand is to be spread over the pavement after initial compaction has been completed. This jointing sand is to be spread as soon as is practical after initial compaction and prior to the termination of work on that day.

.2 The jointing sand is to be broomed to fill the joints. Excess sand will then be removed

from the pavement surface and the pavers are to be compacted again to settle the jointing sand.

.3 After jointing sand has been installed and the pavement surface swept clean, final

compaction will be accomplished by not less than two passes of a plate compactor.

.4 Sweep surface with fine bristle brush and use a leaf blower to remove all residue from surface of pavers.

.5 Wet surface 200 sq. ft. at a time, ensuring wetting of one area is complete before starting a new area. Start at bottom of slope gently wetting areas for 30 seconds without displacing sand. Wet areas at least twice.

.6 Protect surface from rain for 90 minutes after wetting to ensure surface dries completely.

3.12 FINAL COMPACTION OF PAVERS



.1 After jointing sand has been installed and the pavement surface swept clean, final compaction will be accomplished by not less than two passes of the compactor.

.2 Final compaction will proceed as closely as possible following installation of jointing

sand and prior to the acceptance of any traffic.

.3 Inspection by the Consultant will determine whether a second application or partial application of jointing sand is required.

3.13 MARKINGS

.1 Provide barrier-free markings at barrier-free access zones as indicated on drawings. 3.14 CLEANUP

.1 Sweep clean all paved areas of excess sand and dirt.

.2 Pick-up and remove from the site all surplus materials, equipment and debris resulting from this section of the Work.

3.15 TOLERANCE OF SURFACE PROFILE

.1 All surface and pavement structures will be true to the lines, levels, grades, thickness and cross sections as shown on the drawings.

.2 All pavements will be finished to lines and levels to ensure positive drainage at all

drainage outlets and channels. In no case will the cross-fall of any portion of the pavement be less than 1 percent.

.3 The pavement surface will not deviate by more than 4 mm in 2 m from a straight edge

laid in any direction. Height deferential between any two pavers shall not be more than 3 mm.

.1 Place materials in a secure place and in strict accordance with manufacturer’s recommendations.

.2 In the event of damage or theft of materials, make all necessary repairs and replacements to the approval of the Water Feature designer and at no additional cost to the Owner.

1.9 WATER FEATURE DESCRIPTION AND PERFORMANCE

.1 The water feature consists of 3 pumping systems. The “skin pool” pump system provides water to the surface of the pool. The jet pump system provides water to the 7 display jets, and the filtration pumping system maintains clean water. Water feature to have a water treatment system, a water level control system, a filtration system with automated UV and bromine and ph control



water treatment system, and a wind override system. The overflow, jet system and filtration systems shall re-circulate the water.

.2 The pool can operate as a quiet reflecting pool, or as a pool with jets operating. When jets are on and overflow system is off, pool will fill to 50mm design level before stabilizing. In winter, the water feature systems are off and the pool becomes an ice rink. The rink system is documented elsewhere.

.3 All water for pool is stored in large reservoir adjacent to new washroom building.

.4 When both water skin and jet systems are off (every night and for special events), the pool will drain to empty through perimeter slots to the trench drain and back into the reservoir. During special events, the pool can be emptied without water loss and used as a plaza space for activities. A separate drain system in trench provides for wash down of pool floor to sanitary to avoid contamination of clean water in reservoir.

.5 The water skin pump system pumps approximately 22mm of water depth over trench edge from the West half the pool oval, and fills the pool to approximately 50mm, overflowing the drain trench at the East end of oval before returning to the reservoir.

.6 The overflow pump is operated by a variable speed drive (VFD) to allow slow start up and shutdown and adjust flows for best efficiency and least turbulence on pool surface. The flows are controlled from the fountain control system (see specification section 13155 for further description).

.7 When water skin pump and jet pump turns off for night, filter pump temporarily turns off, 3 way ball valve switches from pool position to reservoir position, directing all filtered water to the reservoir, and filter pump restarts at lower (50%) flow. Just before the water skin and jet pump start up again in morning, the filter pump turns off, the 3 way valve reverses to have 2/3 flow to pool and 1/3 flow to reservoir.

.8 The jet pump system is comprised of 7 large aerating jets placed in random angle and trajectory ranging from 55 -75 degree angles as noted on drawing. Jets can be raised or lowered automatically and an ALTERNATE PRICE is to be provided for individual animation as per 2.1.9. The jets are presently specified as water independent aerating jets. These jet types will be finalized by DEW testing prior to jet installation. See Landscape Drawings for shroud orientation and angle. Jet sprays and trajectories will be demonstrated and adjusted on site.

.9 All jets are operated by a single variable speed drive (VFD) controlled pump to allow for programmed variable heights of display from 2.5m to 4.5m high. The fountain heights are controlled from the fountain control system (see specification section 13155 for further description).

.10 Filtration pump operated by a variable speed drive (VFD) to allow for programmed full flow during day and half flow during night mode. The filtration flow is controlled from the fountain control system (see specification section 13155 for further description).

.11 A high rate sand filtration system filters the water continuously in the entire pool/ reservoir system at a 30 minute turnover rate.

.12 An automated water treatment system chemically treats the water with bromine through an erosion feed brominator, and automatically monitors and adjust bromine and ph levels to meet Health standards, maintaining bromine at 3-5ppm and PH at 7.2-7.8.



.13 All 3 pump systems shall each have a UV sterilizer providing final disinfection treatment to all water flow before being discharged into areas accessible to the public.

.14 A turbidity meter (nephelometer) is installed on jet ump suction to measure clarity of water as per Health Department. Interface with water feature control panel so that when turbity rises above 0.3ntu, the jet and water skin pumps turn off , and water filtration continues until turbity level is within acceptable levels. Skin and jet pumps can then resume their program.

.15 A water meter has been incorporated to monitor water consumption as per Health Department requirements.

.16 The jet display pump shall be interfaced with a wind sensor to allow automated adjustment of spray heights to provide proper containment in various winds conditions. Programming as per specification section 13155.

.17 All pipe and conduit slope back to the pump room without traps or as noted otherwise.

.18 Pipe at low points in trough as noted shall have easily removable threaded caps or drain plugs to drain systems.

.19 All low points of pipe in pump room shall have valved drains piped to sump.

.20 Water level is automatically controlled by a remote water level sensing unit in the pump room that has an equalizer pipe to the reservoir. Water level in reservoir can be seen through a clear acrylic sensor tube at wall of pump room. Water level sensor is interfaced with autofill valve via water feature control panel to allow water levels to be maintained automatically.

.21 The reservoir can be drained by using the filter pump backwash and opening manual bypass to sanitary system. Estimated drain down is 60 minutes.

.22 An auxiliary water makeup in the form of pool collected rain water is plumbed to the reservoir. The reservoir water level controller programming will allow for additional water level storage and fluctuation.

.23 Excess water in the reservoir is removed via the 100mm wall mounted overflow to the sanitary sewer system.

1.8 SYSTEM DESCRIPTION & PERFORMANCE

.1 Operation:

.1 The water feature system operation is described in Water Feature Mechanical section 13154.

.2 Final programming to be determined after on site demonstration of various modes.

.3 Lighting to be by site electrical. Coordinate work with water feature electrical.

.4 The control panel shall operate all pumps automatically by means of a PLC and have a manual override. The jet spray pump systems shall operate 16 hours per day.

.5 The filtration system is to be individually controlled and to be set to operate for 24 hours per day. Filtration system shall operate at half flow from 11pm to 6am daily.

.6 When water skin pump and jet pump turns off for night, filter pump temporarily turns off, 3 way ball valve switches from pool position to reservoir position, directing all filtered water to the reservoir, and filter pump restarts at lower (50%) flow. Just before the water skin and jet pump start up again in morning, the filter pump turns off, the 3 way valve reverses to have 2/3 flow to pool and 1/3 flow to reservoir.

.7 An automated water level control system including an autofill valve and an ultrasonic water level sensor will monitor low, medium and high (normal water levels). The sensor is interconnected with the pumps so that the pumps cannot energize unless the water level is at the correct elevation. The water level is at normal when the pool is full of water. At



normal water level, the system runs. When the water level drops down due to low water, the sensor interfaces with the automatic fill bypass solenoid valve that opens to add water to the reservoir through the filtration piping. When water raises back to normal, the autofill valve shuts off. If water can not be made up fast enough and water level continues to drop in the reservoir, and the autofill valve closes and the pumps will shut down. Water levels will be measured in the reservoir. The water level will normally drop when all jets running full.

.8 An automated ultrasonic wind sensor monitors wind speed and direction. Wind sensor interfaces with control panel and jet pump VFD to control jet heights. When winds are low, jet sprays operate a full height programming. As wind speeds increase to perhaps 12-15mph (adjustable), the spray automatically drop to perhaps 60% full program height. When winds further increase to 15-20mph (adjustable), wind sensor signals VFD to dop jets to 40% full program height. Above 20mph (adjustable) jets are off. Provide 45 second (adjustable) time delay to prevent short cycling.

.9 A turbidity meter (nephelometer) is installed on jet ump suction to measure clarity of water as per Health Department. Interface with water feature control panel so that when turbity rises above 0.3ntu, the jet and water skin pumps turn off , and water filtration continues until turbity level is within acceptable levels. Skin and jet pumps can then resume their program.

.10 The PLC controller is to be interfaced with future building automation system. Provide on/off contacts for each pump, for low water in reservoir alarm, for high water in pump room alarm. Provide continuous display of water levels in reservoir in relation to operating and static water levels and overflow level. Interface to water treatment control panels and 3 x UV control panels and associated alarms.

.11 For special events, the pool can be drained by bypassing the pool filter water to the reservoirs and opening the pump dump valve in the reservoir. A separate switch on the control panel face will provide manual override for this operation.

.12 The system is to be grounded and bonded as per Code

.13 Provide ALTERNATE PRICE for incorporating individual control for display jets (7) automation:

.1 Provide wiring for each water switch as noted in 13154-2.9. Size for 24vac 2.9A inrush, 1.7A holding, with max voltage drop of 3%. Cable to be shielded Total 7 water switches.

o Possible sequences:

Jets stable at same height at any programmed look.

Jets oscillate from 300mm ht to 2400mm ht Generally, jets will be stable at a given look for 15 minutes to 1 hour

duration before changing.

Allow for up to 25hrs of programming after on site demonstration.

• At startup of pump when pump system is off due to programming or due to power failure, jets shall always spray to height of 200mm above jet shroud for a period of 20 seconds prior to being energized to programmed height. This is a safety warning signal to warn patrons that the fountain is about to begin operation.
