In July of 2012 ZALIG under the platform of Stewart Weir & Co. Ltd. began a geotechnical site investigation & report for the above mentioned development on the behalf of Pembina NGL Corporation and the final report is expected to be complete in November. The project includes the construction of small to large diameter, above ground and underground, storage tanks, office/equipment buildings, flare stacks, and a storm water retention pond.
The purpose of this investigation was to address the following issues:
Ground surface elevation at each borehole
Installation of standpipe piezometers to monitor stabilized groundwater
levels in boreholes
Obtaining soil samples (as per ASTM D1587) at 0.75 m
Performing pocket penetrometer readings on soil samples
Standard penetration test (SPT) at 1.5 m interval in all boreholes
Obtain stabilized groundwater table readings
Conduct CPT and shear wave velocity testing at selected locations
Conduct suitable laboratory testing to permit the development of geotechnical design parameters for earthwork and foundation design
Laboratory testing includes the following:
Moisture Content ASTM D2216
Sulphate Analysis ASTM C1580
Atterberg Limits ASTM 4318
Consolidation Test ASTM D2435-90
Unconf. Comp. Strength ASTM D2166
Hydrometer Analysis ASTM D421/422
Fixed cost
Acheieved scope requirements
Project was completed ahead of schedule
