Bridge Inspection & Assessment

Inspections extend bridge lifespans. Diligent inspection programs and strategic maintenance plans are critical to help extend a bridge’s lifespan...

Stantec’s bridge inspection professionals understand every aspect of bridge management and apply this knowledge to help our clients assess the safety of their in-service bridges while increasing reliability and structure service life. Our work helps them reduce monitoring, maintenance, and reconstruction/replacement costs. Before we conduct an inspection, we look for the best methods to access the structure as efficiently and cost-effectively as possible. Specialized techniques like SPRAT-certified rope access and using dive teams give us hands-on access to critical locations on bridges that are otherwise difficult to see or where using traffic control or standard access equipment is not feasible. As a result, we can provide our clients with more detailed inspections, increasing accuracy and structure safety, and minimizing traffic disruptions.

Don’t look down

Hanging 900 feet above the Colorado River, Stantec bridge inspectors do what it takes to keep this bridge safe for the travelling public.

<p><b>Nick Cioffredi</b>: So a lot of people ask if you get nervous or scared when you're working at height but you learn through extensive training and time on rope that you trust your gear, you trust your setup, you go nice and slow and steady, make sure that everything is rigged properly and it takes all the fear out of it.</p> <p>We've got a crew of seven, based out of Denver. All trained bridge inspection team leaders and assistants who are out here inspecting the Michael O'Callaghan Pat Tillman Memorial Bridge.</p> <p><b>Tony Illia (NDOT – Nevada Department of Transportation):</b> we've been able to rely on Stantec to provide resourceful and accurate testing and assessment of the bridge . In addition to that, Stantec has really been a partner to us. Part of the NDOT family in helping us provide engineering services and making sure the bridge is functioning as it should be.</p> <p><b>Nick</b>: The structure is an open spandrel arch. We actually are able to, using our rope access, inspect the spandrel columns, the columns on all the approach spans, the arch, the interior of the arch, where we're actually on rope inside the arch, going all the way down to the skewbacks and back.</p> <p><b>Drew Houser</b>: This bridge is just under 1000 feet. All right above river level. When you're out there at the middle of the bridge at center span and you look down, you're looking about a fifth of a mile down to the river.</p> <p><b>Nick</b>: nine times out of ten, the bridges are in great shape. We're just going through that routine inspection making sure we're documenting any deterioration that's happening so that we can program for that maintenance or that rehabilitation down the road. When you do find that, the flaw in that bridge that could potentially be serious, we're there to catch it.</p> <p><b>Drew</b>: The Bridge Inspection Program all started with the catastrophic collapse of the Silver Bridge. When that happened, they realized that America's infrastructure needed to be looked at and some portions of it were crumbling. That lead to the Bridge Inspection Program.</p> <p><b>Nick</b>: What we do, nine times out of ten, we're inspecting bridges within our own communities or within our own state and you'd be amazed how many bridges you drive over on a daily basis and don't even realize that you're on a bridge. Our job out there is to keep our neighbors safe. It is to keep that community that we live and reside in safe.</p>

The Coast Meridian Overpass was due for a detailed inspection.

<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>
