Challenge

The City of Brampton had been using dTIMS for their pavement management system since 1990. In 2017, the City was in the midst of establishing their Corporate Asset Management (CAM) team to oversee additional assets that the City is responsible for. As part of the CAM, the City began a move towards more evidence-based decision making for their asset management decisions.

Historically, bridge inspections at the City are performed by contract, and the Contractor provides the software for accommodating the associated data. However, the software is proprietary with limited transparency and flexibility. In addition, the license for the software will expire at the end of the contract period.

Solution

The City and Deighton worked together to expand dTIMS to include bridges. The City's OSIM (Ontario Structure Inspection Manual) data provided the required structure and element data for all City owned bridges. Analytical models and other required dTIMS parameters were developed for the bridges and a strategic plan was developed.

As part of the CAM initiative, the City had developed a risk framework that comprised of various metrics and scores to determine probability and consequence of failure. This framework was included in dTIMS which provided the City the ability to look at their risk profile under various funding scenarios.

Results

The City has included bridge risk in dTIMS based on the city's framework for probability and consequence of failure. In addition, evidence-based strategic planning using OSIM data was integrated into dTIMS.
