Construction site in Falconridge

The Calgary inspectors of developer and contract construction are the heroes of my paper. The only two specifications of ours that actually differ from the manufacturers recommendations are, number one: we insist on gravel or sand bedding for all our pipes and for the entire pipe zone. Calgary has widely varying soils and unless the native soil happens to be sand or rounded "non-injurious" gravel, the contractor has to bring in enough to completely surround the pipe.
