Shelby Engineering Ltd. (Shelby) has completed a Geotechnical Investigation for a proposed light industrial development to be located in Redwater, Alberta.
Ms. Suparna Malhotra of K & M Business Solutions authorized this evaluation on July 31,2015 subsequent to acceptance of our proposal (#14883) dated July 29, 2015. Following a revision of the scope of the project, the proposal was revised and re-issued as proposal # 14883 ROl,dated August 13, 2015. This report is subject to the Standard Terms and Conditions for the Provision of Services by Shelby Engineering Ltd.,appended hereto.
The proposed development is expected to comprise a typical,heated structure with a footprint of approximately 10,000 square feet. Attendant asphalt surfaced pavements and gravel surfaced yard(s) will also be developed at the site. It is understood that the building will incorporate a grade supported floor slab without a basement.
The field drilling and sampling program was conducted on August 18, 2015, comprising nine test holes extending to depths ranging from 2.3m to 6.25m below existing grade.
Recommendations are provided herein for the design of building foundations, grade supported concrete floor slabs and pavement areas.
2.0 SITE DESCRIPTION
The site is a portion of the quarter section legally described as NE 3′, Section 20,Township 57, Range 21, West of the 4th Meridian. It is located in Sturgeon County, just east of the Town of Redwater, Alberta.
The study area is located on the southeastern part of the quarter section, to the south of an oil well access road. Currently, the site is a vacant pasture land bound by wetlands to the west and south, more pasture land to the north, and Range Road 214 to the east. The site is relatively level, sloping down slightly towards its northeast corner. The maximum difference in elevation, as measured at the test hole locations, is 1.65m.
The field investigation, supervised by Mr. George Doohan of Shelby, was conducted on August 18,2015 and entailed drilling a total of nine test holes using a truck mounted drill rig equipped with solid stem augers. The test holes were drilled to depths ranging from 2.3m to 6.25m below existing grade.
Disturbed soil samples were obtained at 300mm below existing grade and thereafter at regular depth intervals of 0.76m for moisture content determination. Standard Penetration Tests (SPTs) were conducted at selected depth intervals. A continuous field log was maintained and all samples were returned to our laboratory for visual confirmation of our field logs and for pertinent laboratory testing.
Laboratory testing included visual classification and determination of moisture content on all soil samples. Tests to determine Atterberg limits and concentrations of water soluble sulphate salts were also conducted on select samples. All field and laboratory test results are presented and/or referenced on the test hole logs.
