<strong>MULTI</strong>-<strong>PLATE</strong>2. AssemblyMulti-Plate assembly is accomplished by bolting adjacent longitudinal andcircumferential plates to form the full length and circumference of thestructure. All structures are supplied with engineering drawings showing thecorrect positioning of the plates, plate lapping details, as well ascomprehensive backfilling instructions._NOTEDrawings, including the unbalancedchannel layout for arches, areprovided and will vary dependingupon the shape and complexity of theinstallationField ConstructionAssembly may be undertaken plate-by-plate, or by sub-assembling arcs of thestructure before lifting into the excavation to minimize field construction timeTYPICAL ASSEMBLY TOOLS• Spud wrenches• Clevises• Cables and slings• Air impact tools• Turnbuckles• Eyebolts• Alignment pins, prybarsDEBOLT CREEK, AB - <strong>MULTI</strong>-<strong>PLATE</strong> ASSEMBLY3. Backfilling and CompactingFree draining granular materials shall be used in the engineered backfillenvelope. Backfill shall be placed in 200mm lifts and compacted to aminimum of 95% Standard Proctor Dry Density.Typical equipment required for backfilling in critical backfill zone• Small tracked/wheeled equipment for spreading (e.g. D4/JD450/Bobcat)• Walk-behind compactor (e.g. Bomag BW75)• Vibrating plate tampers• Ride-on compactor up to 15 tonnes (where feasible)• Tracked (D6) equipment for spreading material when backfillis more than 1.5 m above structure• Water supply• Shovels/rakes/other equipment as appropriate for manpower available• Material supply by truck as requiredGRANT MACEWAN BOULEVARD, AB -<strong>MULTI</strong>-<strong>PLATE</strong> WITH BEVELLED END
