The three-edge bearing test is a method that determines the strength of a concrete pipe by applying a specific load in a controlled environment such as the precast plant. Proper classification of the pipe is based on this test which follows the standards CSA A257 or ASTM C76. RELATED: Video: Pipe sample from 1842 shows […]
Are you still wondering what is the service life of a concrete pipe? Is it true they last 100 years? If that is the case, listen to Mel Marshall’s video about durability. Here, he shows what the first-known sanitary pipe installation in North America now looks like. Using pieces of pipe both from 1842 and […]
With this video tutorial, you will learn how to design a concrete pipe using a free web-based software called “PipePac.” We will walk you through a quick example which allows you to understand the dynamics of the software. RELATED: Tutorial: PipePac Indirect Design Method
In this video, you will learn the basics of the Indirect Design Method, and also how to design a concrete pipe properly by using a free web-based software called “PipePac.” We will walk you through two design examples which allows you to have a better understanding of the software and the different parameters that are […]
In December 2019, the Province of Ontario announced that they were phasing in a new regulation under the Environmental Protection Act that would result in a reduction in construction costs by making it easier to reuse excess soil generated during construction activities to minimize waste and to provide clear rules on managing and reusing excess […]
“TULLOCH understood the need to collaborate early,” says Dan Haggerty of DECAST. “I received the initial call from John McDonald. He knew that consulting with those who would build and install the components would make the design and project planning processes efficient. And it ensured his design would consider all the challenges associated with this […]
Harbourside Engineering Consultants (HEC) was retained by Construction Demathieu and Bard (CDB) to develop the structural design and temporary construction works required for the Calamity Creek Culvert Replacement Project, just north of New Liskeard, Ontario. The purpose of the project was to replace and decommission an existing cast-in-place reinforced concrete, single cell box culvert having […]
The project located in Calgary, Alberta, consisted of twinning the existing reinforced concrete pipe (RCP) sanitary sewer. As part of this project, a flow balancing chamber would be required to balance the flow between the existing RCP sewer and new RCP sewer. The initial design for the chamber called for either cast-in-place or a precast […]
With communities seeing more and more surface flooding due to larger intensity storms and inadequate underground infrastructure, the City of Calgary is being proactive in mitigating flood waters in new upcoming communities. Anticipating flooding at the design stage not only adds future savings to homeowners but also has a big positive environmental impact on future […]
The iconic 405-acre Stanley Park borders downtown Vancouver, British Columbia, and sits pristinely on Burrard Inlet offering visitors a unique glimpse at what the natural setting of Vancouver looked like before urbanization. Nestled inside Stanley Park is Beaver Lake, which is one of the very few freshwater lakes existing in Vancouver, and the outlet Beaver […]
