Project Profile: Bay of Quinte Skyway Bridge

02/16/21

The Bay of Quinte Skyway Bridge gets traffic from approximately 5,200 vehicles per day. The bridge was constructed in 1967 and was due for updates and maintenance, including replacement of decks and pier repairs. Our Construction Quality Verification team in Kingston has been providing quality control for the Ontario Ministry of Transportation, Aecon Group, and McIntosh Perry. Concrete and grout quality is one of the many factors our staff regularly monitor on this major project. These tests confirm whether the delivered materials meet the required construction specifications. For example, just a small change in water to cement ratio will diminish the strength of the cement making the concrete structurally unsuitable for the task.  Small issues caught early will avoid bigger problems later.

The bridge rehabilitation will benefit the surrounding Prince Edward County and Tyendinaga Mohawk Territory for generations to come. We are proud to have been a part of this project that will benefit the community.

Our five locations allow us to collaborate with varied clients in many different sectors across Canada. Interested in what other services we offer? Visit our website to learn more.

How to Ensure Quality Building Structure & Envelope Sciences During Construction

02/28/19

Cambium’s Building Structure and Envelope Sciences Team – Providing construction engineering support services to help clients make better decisions.

Cambium is proud to introduce our Building Structure and Envelope
Sciences team serving advanced construction projects throughout
Ontario. These services augment the inspection and testing
components of Cambium’s existing Construction Monitoring services.
Our team commitment and experience enhances client confidence in
each development project, which is best summarized by our mission
of Guiding Good Decisions.

Our goal is to contribute value to every project and assist our clients
to achieve successful outcomes. Cambium now offers further
construction engineering support services in the critical pre-design
stage, design tendering, and contract administration. Our team
understands the complexity of construction materials and techniques.
This understanding often translates to solutions for design constraints
and recommendations for better materials management.

As part of Cambium’s construction monitoring services, our qualified inspectors provide Quality Assurance (QA) and Quality Control (QC) onsite inspections to ensure that all components of the project are built to appropriate specifications. Our team includes certified Canadian Welding Bureau (CWB) Inspectors, inspection staff with industry certifications in welding, coatings, steel, and concrete testing and inspection, including non-destructive testing (NDT), all experts in their respective fields.

Our Building Structure and Envelope Sciences team provide:

  • CSA S16 Structural Steel & CWB Certified Welding Inspections
  • Building envelope inspections including window and curtain walls, rain screen and cladding
  • Roofing Systems Design, Tendering, and Contract Administration
  • Roofing System Inspections and Reviews
  • Existing Asset Condition Reviews
  • Failure Analysis Investigations
  • Reinforcing Steel Verification
  • Machinery inspections and assembly reviews
  • Concrete (Grout/Mortar) Testing and Monitoring

We advocate for our clients that quality be built into the project from the start to avoid costly changes, correction, or delays. The investment in Cambium services is always a positive return for the project.

Asbestos, a Dangerous Designated Substance Not Visible to the Eye

03/8/17

In a recent article, Asbestos Exposure is Still Making People Sick,  CNN reportes that the US Centers for Disease Control and Prevention continue to see people suffer asbestos-related medical issues.

In Ontario, Designated Substances are defined as “a biological, chemical or physical agent to which the exposure of a worker is prohibited, regulated, restricted, limited or controlled.” Asbestos is one of 17 designated substances that present health and environmental risks. It can be found in a variety of everyday materials that may be present inside your work and home environment like vinyl sheet flooring, vinyl floor tiles, plaster, vermiculite insulation, ceiling tiles, drywall joint compound, and sealants.  It’s fibres are smaller than the diametre of human hair and even smaller than glass fibre. The risk for exposure and inhalation increase when the fibres are disturbed and exposed to air through the poor condition of the material, demolition/construction, or regular maintenance.

A problem with illnesses related to asbestos is the latency period. It takes a long time for the effects of asbestos exposure to develop and is hard to determine when the exposure happened to an individual.  In Ontario, asbestos is a designated substance and governed under the Occupational Health and Safety Act, Regulation 278/05, Asbestos on Construction Projects and In Buildings and Repair operations.  It is important for businesses to have a non-intrusive compliance survey completed for the health and safety of your employees.  If the presence of asbestos is confirmed, a management plan is required to provide instructions and training for staff and maintenance on the proper procedures to prevent fibres and asbestos containing materials (ACM) from being exposed in the work environment.

Additionally, prior to any renovation or demolition, business and home owners hiring an independent contractor are required to complete an intrusive survey to determine the presence of materials which may be uncovered during those activities. Tearing down walls, removing ceiling tiles or insulation – these types of actions can disturb and release ACM fibres into the air.  It is always best to put the safety of your family, employees, and contractors first to ensure they are not exposed to this designated substance.

The removal, disposal and management of the asbestos abatement should be done by qualified professionals. Cambium specializes in Designated Substances Surveys (DSS), Asbestos and Hazardous Material Assessments. If you have any concerns or have questions, Cambium can assess and test for designated substances and develop an abatement plan to manage the removal.
