GEOTECHNICAL INVESTIGATION PROPOSED 6-STOREY RESIDENTIAL BUILDING 499 DUNDAS STREET NORTH

The field investigation program was conducted under the supervision of a member of our engineering team, who logged the subsurface conditions encountered at the boreholes, effected the subsurface sampling and testing, and monitored the groundwater conditions. [...] 3.0 EXISTING SITE CONDITIONS The site is bound to the northeast by residential buildings, to the southeast by Jarvis Street, to the southwest by Dundas Street North and to the northwest by Easton Street. [...] Based on the anticipated condition of the engineered fill materials and the underlying soil condition encountered at the boreholes, the site can be classified as a Site Class C as per OBC Table 4.1.8.4. [...] Based on the results of grain size analyses and our experience, the hydraulic conductivity and infiltration rate of the native inorganic soil types encountered at the boreholes are estimated and provided in the following table and may be used for storm water management purposes: MATERIAL PERMEAVITY (K) (cm/sec) INFILTRATION RATE (mm/hr) Gravelly Sand to Sandy Gravel 1 x 10-2 150 (Enclosures 7 to 9. [...] The analytical results and environmental assessment findings must be disclosed to the receiving site owner(s) and approval by the receiving site owner(s) be obtained prior to exporting/transferring the materials.
