1)
| Project Consultation – the local CONTECH Project Consultant evaluates your needs.
|  |
| 2) | Design – using state-of-the-art bridge design procedures, your precast structure is designed to meet any code, loading or geometry requirements. |  |
| 3) | Manufacture – Quality is assured through controlled conditions for plant-produced concrete products. |  |
| 4) | Transportation – Arch units arrive on flat-bed trucks ready for installation. |  |
| 5) | Arch Units – Bridge units are lifted off the truck, rotated and set on strip footings, a base slab, or a deep foundation system. |  |
| 6) | Foundation – Hardwood wedges lock the arch in place on the footing until the keyway is grouted. |  |
| 7) | Twin-Leaf Arches – Larger twin-leaf arches are joined by the patented BEBO® crown joint. |  |
| 8) | Joint Seal – Arch units are grouted in the keyway and joints are scaled using a commercial joint wrap. |  |
| 9) | Wingwalls - Precast headwalls and wingwalls often facilitate an entire structure being set in one day. |  |
| 10) | Backfill – Concrete arch stiffness allows backfill to be placed and compacted quickly. |  |
| 11) | Finished Bridge – The finished bridge is quickly ready for traffic. Many aesthetic end treatment options are available. |  |
