Coast Meridian Overpass Detailed Inspection

Bridge inspection with nearly no traffic delays

Port Coquitlam, British Columbia

When it comes to tax payer dollars, bridge management is often low on a municipalities’ priority list. Similar to a new car needing oil changes, a new bridge requires regular inspection and maintenance. To support public safety across the decades, we need detailed inspections.

The City of Port Coquitlam brought us in as partners to develop an inspection and maintenance plan for the cable-stayed Coast Meridian Overpass. Our approach avoided public inconvenience by reducing traffic disruptions, as would have been the case in a more traditional bridge inspection. Our team of certified industrial rope-access climbers, who are also registered professional engineers, offered maximum value to the City.

Completed in August 2016, this was the first detailed inspection of the bridge since it was built in 2010. Using the BC Ministry of Transportation and Infrastructure bridge inspection rating system, we delivered a comprehensive condition report. Our specialized access bridge engineering inspection team completed the task with minimal traffic disruptions and under the highest safety standards.

With our additionally developed 10-year maintenance program, the City of Port Coquitlam is better prepared to optimize a bridge management strategy for years to come.

<p>Ryan Nataluk: You wouldn't just buy a car and never put new tires on it or do an oil change with it. Well bridges and infrastructure, they need their oil changed every once in a while to keep them up and running.</p> <p>Kip Skabar: A typical bridge inspection is to actually have an engineering judgment according to an established set of criteria In this case, there's over 40 different bridge component types that have to be evaluated. The only way to access some of these components is by industrial rope access in this case</p> <p>Marie-Andreé Paulhus: When I was studying, I was a rock climber. I didn't know much about “rope access engineer.” they talked to me about they did rope access and I was like, &quot;What? That's amazing. I want to do that.&quot;</p> <p>Niall Eivers: There's a lot of different tasks that's involved, different personnel. We have crews of 8 to 10 people on-site at one time, different types of equipment machinery.</p> <p>Kip: There's not too many firms out there that actually have that expertise to put engineers up close and personal with cable-stayed structures such as this at high elevations.</p> <p>Ryan: we're inspectors first and we're climbers second. We use the climbing as a tool to inspect. You need to know material properties of steel, concrete, timber, so you know when they sit in the elements over time, how they deteriorate, and most importantly, how our clients can repair them or protect them. I've climbed many mountains around the world and dropped into a lot of caves. and so Once I learned that I could actually use my skills to perform, use my climbing skills to perform engineering, it was exciting for me.</p> <p>Kip: By doing an inspection like this, we're actually setting providing a set of baseline data in order to help us better manage the asset over its lifespan. we're following the Ministry standards for bridge inspection in such a way that the condition ratings are applied in a very similar manner by qualified inspectors so that that inspection form can be compared to all the other precedent type of bridge inspections that have been done, and therefore, the end result is much more valuable to the city.</p> <p>Steve Brown: It was interesting, when we did go out to tender, Stantec were the only ones that actually had climbers onboard. The rest we're going to be doing it by binoculars and by what they called a visual inspection. I think just by having climbers, we're getting a closer inspection, a far greater inspection.</p> <p>Kip: I’m really excited to bring the team together today and its really rewarding to see everything happening very safely and going off according to our plan. Hopefully you’ll see Stantec inspectors one day hanging off of other cables in the area, and we’ll be doing it safely and we’ll be helping our clients to better manage their structure assets over the entire lifespan of the bridge.</p>
