10Round and Pipe Arch Shapes - Corrugated Metal Pipe GalvanizedAluminized (ALT2)AluminumPolymeric CoatedSmooth Lined MetalThere are several different types of CMP each has different physical characteristics and recommended environments. There are several other types of CMP such as Aluminized, Aluminum and Poly Coated that can give you a 75 to 100+ year life span depending on the gage and environment. The pipe we put in today is not the same pipe you may be relining.
11Aluminum Box Culvert (One of many type of Plate Options) TEXAS Department of Transportation Saved $50,000 over replacing the bridge while still maintaining traffic flowWith 134 different sizes, Aluminum Box Culvert offers a low profile shape great for reline old concrete box culverts and short span bridges.

14Hydraulics Inlet Control vs. Outlet Control When designing a structure hydraulically, two flow scenarios must be checked. They are inlet control and outlet control. Each scenario has a unique set of factors that affect the performance of the culvert.With inlet control - the pipe can carry more water than the inlet can actually let in so the limiting primary factors are the end area and the geometric characteristics of the inlet.With outlet control - the inlet can let in more water than the pipe can carry so various factors beyond the inlet end come in to play in the flow characteristics of the structure.Which of the structures shown are likely to be an inlet controlled structure? (the ALBC)What mode of flow is the UF storm sewer likely operating under? (outlet control)14

33. Two Harbors, MN 2 – 13’ span 2-Flange Tunnel Liner Plate State Aid Project , BridgeThe relining process with Tunnel Liner Plate allows the historical nature of this structure to stay in tact. We can make many unique shapes out of our plate products that can be easily installed by multiple contractors. In most cases special equipment is not required.

Just like pipe, Contech has a variety of Bridge Systems to choose from for almost any application. What system best fits my application? The answer depends on a number of different site constraints, but most times the best place to start is with the overall bridge span required.At first glance, you may be overwhelmed with all of our bridge options. When do I use Plate…When do I use Precast…When do I use Truss? The type of system will depend on your specific project needs, one place to start is working by with your local Project Consultant, who can help evaluate your site and assist in structure selection.Here are the span ranges for each bridge type:Plate ranges from 5 ft. to 52 ft.Precast from 12 to 102 ft.Pedestrian trusses will take you to 250 ft. using a conventional truss design. For spans longer than 250’, we use a cable stayed design.Vehicular steel truss bridges can span up to 300’ with the Thru Truss offered by our partner, US Bridge.These are all single spans – if you have a larger flow or the need a larger span, you can use any of our structures in multiple span arrangements.Also, notice that we have a lot of overlap with our bridges. Which is why I suggest you work with your local Project Consultant to help identify the best fit for your project.Next Slide
