Steel sheet pile cofferdams are primarily used for constructing bridge foundations, underground storage tanks, drive and receiving pits, land-based outfall structures, utility diversion schemes, and generally any deep excavation on land or water where safe access is required for construction work.

Key Advantages of Steel Sheet Pile Cofferdams:

1. Allows for pile installation in environmentally sensitive areas.

2. Virtually no noise or vibration is generated during sheet pile installation.

3. Assistive technologies, including "water jetting" and "pre-drilling," are used to assist with sheet pile installation.

4. Eliminates overhead work.

5. Specialized sheet pile pressing equipment is available to accommodate site constraints and poor ground conditions.

6. Effective for both sheet pile installation and extraction.

7. Capable of installing single "Z"-section sheet piles, providing design, cost, and project advantages.

8. Newer models offer Tier I and Tier IV engine emissions compliance.
