Design conforms to OPSS 59 performance level 2 maximum displacement requirements. A.2. DESIGN ASSUMPTIONS 1. The current design scheme illustrates a temporary shoring system capable of supporting between 7m and 1.2m of overburden. 2. The current design is based upon the assumption that the assumed existing structure foundation configurations, elevations and loads indicated on the shoring drawings are correct. Should any or all of these assumptions change, redesign of the shoring may be required.

Drill holes for piles, utilizing temporary liners, mud drilling and/or other methods as necessary to prevent groundwater inflow or loss of soil into the pile holes. 2. Provide pile holes large enough that piles may be set plumb despite misalignment of holes.. Set piles, wedge and fill holes with concrete specified. Withdraw liners if used.. Excavate in stages to suit shoring work. 5. Excavate to neat faces for lagging installation. Excavation contractor to shave / trim caisson wall to front face of soldier piles, or as directed by the Owner / General Contractor / Project Manager.. Install lagging in maximum 1500 lifts. Should caving or raveling occur, reduce lift height. Fill all voids behind lagging with granular on site material or imported granular fill rammed in place. Leave no excavation without lagging overnight. 7. In wet ground provide spacers to create 10mm gaps between individual lagging boards, place filter material behind lagging to allow passage of water without loss of soil fines. 8. Do not excavate more than 500 below brace elevations until bracing is installed and stressed. 9. Tieback performance tests are to be carried out. See Design Parameters. Performance test installations and stressing are to be witnessed by the Shoring Engineer. Do not proceed with production anchor procurement or installation until performance test results are reviewed by the Shoring Engineer. 10. All working tiebacks are to be proof tested to 150 % of their design load, held at this load for ten minutes and if no appreciable creep is observed, reduced to design load and lock in at 110%. Halt tieback testing if movement out of site exceeds 12 mm. Notify Shoring Engineer immediately. 11. Tiebacks, braces and/or rakers are to be installed without delay to minimize ground movements. All tieback free lengths are to be completely filled with bentonite-cement fill. F. FIELD REVIEW AND MONITORING BY OWNER 1. Field review and monitoring, as noted below, are integral to the shoring design process. They are required elements of the shoring design presented within these drawings and are necessary to ensure that the shoring system is performing in accordance with shoring design assumptions. 2. In accordance with the Ontario Building Code, TERRAPROBE is to provide (at owner's cost) field review to verify that the shoring works are constructed and are performing in general conformance with the design drawings.. Carry out pre-construction condition survey of all structures within the influence of shored excavations.. Precision level surveying of adjacent structures and ground surface is to be carried out on a weekly basis until new construction reaches street elevation. Increase monitoring as directed by the Shoring Engineer. 5. Monitor all piles for horizontal and vertical movements at their tops and at all anchor points at least weekly. Increase monitoring as directed by the Shoring Engineer. Monitoring of CN Railway Tracks and adjacent shoring walls shall follow CN guidelines.. Vibration monitoring at the shoring wall adjacent to Gardiner Expressway is to be carried out until new construction reaches grade elevation. 7. Inclinometers and multi-point extensometers are to be installed at key locations as shown on the drawings for high-precision pile deflection measurements. 8. TERRAPROBE staff can provide the required monitoring and testing. If monitoring by others, all monitoring reports to be distributed within working days of completion to the Shoring Engineer. All tieback test results are to be provided within working days of completion to the Shoring Engineer.
