Regular bridge inspections in Alberta are called BIM inspections, which stands for the Bridge Inspection and Maintenance System. During a BIM inspection, a certified inspector visits the bridge site and rates the existing structure on its various components. This includes four categories: 1) Approach road 2) Superstructure 3) Substructure... 4) Channel It also contains minor maintenance recommendations and an expected replacement date. These items ensure a seamless transition from the inspection to the next step of maintenance and engineering/construction. The timing of the BIM inspection is dependent on the importance of the bridge and road. It ranges from 21 months for bridges on the primary highway network to 57 months for small structures on local (County) roads. The odd number of months ensures that the bridge gets inspected during different seasons each time. Roseke Engineering Ltd. has certified class B bridge inspectors on staff and has performed many inspections for Alberta Transportation, Counties, M.D.’s, and others. http://www.roseke.com/projects/other/bim-inspections/

Bridge assessments are performed when an inspection has identified a problem and the best course of action must be determined. The most cost effective long term solution is often not immediately known due to the trade-off between small, immediate (repair) and larger, future (replace) expenditures. A bridge assessment identifies all of the options available and estimates their initial (capital) as well as ongoing (maintenance) costs. It analyzes the long term, life cycle cos...t of maintaining the crossing to determine the cost-benefit of each alternative. Essentially it asks, what is the cheapest way to ensure traffic movement across the watercourse (or pedestrians, wildlife, whatever the basic value proposition is). Bridge assessments also provide an initial glance into the main issues the future project will encounter, for example environmental permitting, bridge/road alignments, or unique schedule implications. Roseke Engineering Ltd. has performed many bridge assessments and we always enjoy a new challenge. http://www.roseke.com/projects/other/bridge-assessments/

The right materials testing lab can make or break a project. Sloppy asphalt or concrete testing can cause significant cost overruns, and testers that don’t show up on time can cause major delays. The main certification body for construction materials testing, the Canadian Council of Independent Laboratories (CCIL), requires a yearly audit which includes a site visit to our lab, a fairly rigorous inspection of our lab procedures, and it requires lab personnel to perform tests... in front of the inspectors. Alberta Transportation, as part of their Grading-Base-Paving prequalification, also does a yearly audit which involves a site visit and inspection of an actual project. Roseke Engineering’s materials testing staff have a combined over 70 years of experience performing testing for: Engineering firms: We have performed Quality Assurance (QA) testing for some of southern Alberta’s largest paving projects using our fully stocked mobile laboratories. Paving contractors: Quality control (QC) testing, base and subgrade densities. General contractors: Concrete strength testing, backfill densities, and asphalt. Roseke Engineering’s Lethbridge materials testing lab has performed testing on southern Alberta’s largest paving and construction projects. We are well managed and highly motivated to make your project a success. Give us a call for any of your asphalt, concrete, or aggregates testing needs.

Roseke Engineering was the prime consultant for this bridge replacement in Lethbridge County. The two span bridge was nearing the end of its life and was replaced with another two span type SL-510 standard bridge. The project required significant stakeholder consultation because it was located near Lethbridge city limits and contained many adjacent stakeholders. For example, the road crossed a CP Rail track about 13 m to the east of the new abutment, followed immediately by... a major intersection with the 4-lane Highway 4. On the other side of the bridge, the road contained a 45 degree bend leading into the bridge with residential development on both sides. As southern Alberta’s premier bridge engineering firm for rural bridges and bridge-sized culverts, we are proud to help the County maximize the longevity of their road network in the most cost effective manner. http://www.roseke.com/p/standard-bridges/bridge-file-79604/

Roseke Engineering is Alberta's leading engineering firm for bridge sized culvert projects. Bridge sized culverts provide a solution that are more economical than a bridge but require a greater flow restriction. Hence, they require excellent knowledge of hydrology and hydraulics, as well as the structural and geotechnical aspects of culvert structures. Roseke Engineering's bridge engineering team has designed and managed hundreds of bridge sized culvert projects and we can ...ensure the highest level of service and safety of the travelling public. We are prequalified by Alberta Transportation in the category of Standard Bridges and Culverts as well as class B bridge inspection. We are often involved in the inspection and planning as well as the project delivery stage. Our services encompass the entire project life cycle of a bridge sized culvert, from inspection and assessment through planning and construction. http://www.roseke.com/services/bridge-sized-culverts/
