How Does Post Tensioning System ODM Work?

**How Does Post Tensioning System ODM Work?**.

**Step 1: Design Stage**.

- At the beginning of the process, engineers work on designing the post-tensioning system. This stage involves determining the requirements of the project and creating a plan for the post-tensioning system that will be used.

**Step 2: Fabrication of Components**.

- Next, the components of the post-tensioning system are fabricated. This includes manufacturing the cables, anchorage systems, and other related materials that will be used in the system.

**Step 3: Installation of Post-Tensioning System**.

- Once the components are ready, the post-tensioning system is then installed. This involves placing the cables through the ducts in the concrete structure and attaching them to the anchorage systems at both ends.

**Step 4: Stressing of Cables**.

- After the cables are installed, they are stressed using hydraulic jacks. This process involves applying tension to the cables until they reach the desired level, which helps to strengthen the concrete structure.

**Step 5: Grouting**.

- The final step in the process is grouting. Grouting involves filling the ducts in the concrete structure with a cementitious material, which helps to protect the cables from corrosion and ensures that they remain in place.

**Conclusion**.

In conclusion, the ODM (Owner's Design Memo) post-tensioning system works by designing, fabricating, and installing a system of cables that are tensioned to strengthen a concrete structure. By following a step-by-step process, engineers are able to ensure that the post-tensioning system is installed correctly and functions effectively.
