Site Evaluation & Parameters

Common Existing Site Conditions:

1. Undersized Culvert/Bridge (span)

2. Minimum Rise or Cover

3. Narrow Roadway Width

4. No Head or Wing Walls

5. Damage from Flood(s)

6. Existing Culvert(s) have Detiorated

Invert(s)

7. Roadway Closure - Limited or Not

Practical

8. Rural Location w/Limited Access

Site Evaluation & Parameters

Common New Project Conditions:

1. Limited $$$$$$

2. Permitting & Engineering Required

3. New Culvert/Structure Larger both Span & Length

4. Bottomless (Footings)

5. New Headwalls

6. Water Quality (acidic?)

7. Flood or Wetland Boundaries

8. Aquatic Life “Friendly”

Choosing the Best Plate Product

Project Info to Begin Reviewing Culvert Option(s):

1. Waterway Area (SF)

2. Minimum Span (Ft)

3. Available Rise/Height (Ft)

4. Bottomless

5. Water or Soil “Ph”

6. Surface or Highway Loadings

7. Inlet/Outlet Ends

8. Assembly

Choosing the Best Plate Product FIRST – Grab Resources to Assist in the Process

Choosing the Best Plate Product Project Info to Begin Reviewing Culvert Option(s):

1. Waterway Area (SF)

- Different Size & Shapes

2. Minimum Span (Ft)

- Min or Choose Larger Span?

Choosing the Best Plate Product Project Info to Begin Reviewing Culvert Option(s):

3. Available Rise/Height (Ft)

- Option to “Raise” Road for Structure Value

Engineering (Arch, Arch Pipe, Ellipse)?

Low Profile/Rise

13

Choosing the Best Plate Product Project Info to Begin Reviewing Culvert Option(s):

4. Bottomless

-Full Invert or “Natural Stream Bottom”?

-Abrasion Concern?

5. Water or Soil “Ph” (Stream/Wetland)

-Near “Neutral” or More “Acidic”?

-Structure Backfill Typically Neutral

Rules of Thumb

50 yrs for STEEL

75 yrs for ALUMINUM

Typically Invert Governs Service Life

Choosing the Best Plate Product Project Info to Begin Reviewing Culvert Option(s):
