• Many Division 35 projects involve coordination with the U.S. Army Corps of Engineers or coastal permitting authorities.
• Specs often include elevation benchmarks, tidal effects, and underwater work allowances.
• Pay close attention to materials such as sheet piling, riprap, and corrosion-resistant fasteners.
• Temporary works like cofferdams and floating platforms may be required — confirm in specs.
• Dredging operations and disposal plans should be reviewed carefully in public projects.

1. What type of projects often fall under Division 35?
   Answer: Projects involving special construction such as coastal work, dredging, and unique structures requiring coordination with authorities like the U.S. Army Corps of Engineers.
2. Why is it important to verify elevation benchmarks and tidal effects?
   Answer: Ensuring proper elevation, tide consideration, and underwater work allowances is crucial for environmental and structural integrity of the project.
3. What materials are commonly used in Division 35 projects?
   Answer: Sheet piling, riprap, and corrosion-resistant fasteners to ensure the durability and strength of structures in aquatic or coastal environments.
4. What are cofferdams and floating platforms used for in Division 35 projects?
   Answer: These are temporary structures used to manage water in construction zones, ensuring safe working conditions and compliance with project specifications.
5. How should dredging operations and disposal plans be handled?
   Answer: Review and plan for safe disposal of dredged materials, ensuring compliance with environmental regulations and maintaining project safety standards.

Division 35: Special Construction

🔹 Key Teaching Points

1️⃣ Coordination with Authorities

• Many Division 35 projects require coordination with the U.S. Army Corps of Engineers or coastal permitting authorities.
• Check for compliance with special environmental and regulatory permits that may affect the project's execution.

2️⃣ Elevation Benchmarks & Tidal Effects

• Projects in Division 35 often include specifications related to elevation benchmarks, tidal effects, and underwater work allowances.
• Ensure the elevations are accurately noted and any environmental considerations (like water table effects) are accounted for.

3️⃣ Materials for Special Construction

• Look for materials like sheet piling, riprap, and corrosion-resistant fasteners — critical for durability in specialized environments.
• Corrosion resistance is often a must due to water exposure or aggressive conditions.

4️⃣ Temporary Works: Cofferdams & Floating Platforms

• Temporary structures such as cofferdams, floating platforms, or other water management solutions are often required.
• Confirm their design, safety requirements, and responsibilities for maintenance during the project lifecycle.

5️⃣ Dredging Operations & Disposal Plans

• Dredging operations, especially in public works projects, must be carefully planned, including disposal methods and environmental compliance.
• Ensure waste disposal and mitigation plans align with both legal requirements and project goals.

✅ Wrap-Up Summary

• Division 35 covers specialized construction that requires thorough coordination with authorities, environmental standards, and precise planning.
• Material selection, temporary structures, and dredging operations all need to be handled carefully to avoid project delays and legal issues.
• Special attention is required for projects with water-related construction or coastal impacts — confirm all guidelines and environmental specifications.
