• 😀 There are seven bridges and five overpasses in the project, which require careful planning and execution to ensure safety and quality.
• 😀 Coordination with relevant parties, including liveplan inspection, pre-mobilization checks, and material verification, is essential for successful girder erection.
• 😀 Discipline in planning is crucial for the lifting operations, including determining lifting capacity and simulating lifting cycles based on tool dimensions and site conditions.
• 😀 The work site is located along a national road, requiring careful traffic management in coordination with the police and traffic authorities to ensure public safety.
• 😀 Socialization efforts, including signage and warnings for road users, are important to ensure smooth operations while complying with regulations.
• 😀 Health checks and toolbox meetings are conducted before starting work, ensuring the safety of the team and addressing potential hazards.
• 😀 Girder lifting involves the use of two cranes, followed by a loading test to confirm the girder’s safety for placement.
• 😀 The girder is mobilized using a bumitrack to its designated location, where precise positioning and stability are crucial during the lifting process.
• 😀 Girder installation follows a strict procedure, where the girder is aligned and secured according to survey markings and measurements for precise placement.
• 😀 The final phase involves securing the girder using reinforcing steel at certain points to enhance stability and prevent movement, ensuring proper construction of the bridge.

Q & A

What is the focus of the Trans-Sumatera toll road project discussed in the transcript?

The focus of the project is the construction of the Trans-Sumatera toll road, specifically the Indrapura Kisaran section, which involves bridge work, overpasses, and junctions.

What is the role of girder erection in this project?

Girder erection is a key part of the bridge construction process. It involves using cranes to position large girders in place, ensuring that they are stable and meet specified safety standards.

What are the key safety measures mentioned in the transcript for the erection of girders?

Safety measures include coordination with relevant parties such as traffic management, inspection of materials, health checks for workers, and regular toolbox meetings to address potential hazards.

How does traffic management factor into the construction process?

Since the construction site is located along a national road, traffic management is crucial. It involves coordination with the police, transportation authorities, and the installation of signs to ensure the safety of road users.

What is the significance of the loading test for girder safety?

The loading test ensures that the girder can be safely lifted without failure. It is conducted for 15 minutes with checks at five-minute intervals to confirm the stability of the girder before it is moved into place.

What role does the crane play in the girder erection process?

The crane is used to lift and position the girder. The girder's weight is carefully balanced and moved according to a precise lifting plan, ensuring it aligns with the designated markings and remains stable during placement.

How are the girders positioned accurately during installation?

Positioning the girders accurately is achieved by ensuring the cranes move them in alignment with pre-established marking points. The placement is confirmed using survey team measurements, ensuring the correct positioning.

What is the function of the browsing installed on the girder?

The browsing, installed at the girder’s base every six meters, is designed to stabilize the girder, enhancing its support and ensuring it remains locked in place.

What are the key stages in the girder installation process?

The key stages include checking the girder, conducting a loading test, mobilizing the girder to the installation site, carefully lifting it with the crane, and securing it in place following pre-set markings.

Why is coordination with local authorities and medical staff critical during the project?

Coordination with local authorities is necessary for traffic management, while having medical staff on standby ensures that any health emergencies or accidents are handled swiftly, maintaining safety during the construction process.
