Project Overview:

The Park Royal Residential Development was a significant construction project involving the erection of tower cranes for a three-block residential complex. The project spanned varying heights, with buildings ranging from 36 to 96 meters in height. The successful completion of this project required strategic planning, careful crane selection, and efficient crane installation and removal procedures.

Challenges:

Diverse Heights: The three-block complex had buildings of different heights, ranging from 36 to 96 meters. This required a tailored approach to crane selection and placement to ensure optimal coverage for all construction areas.

Height and Load Considerations: Erecting and operating tower cranes at such heights presented challenges related to structural stability, wind loads, and lifting capacities. Ensuring safety and stability throughout the construction process was crucial.

Freestanding Crane Erection: The installation of the Moritsch RTM280 freestanding crane on the highest residential block, reaching a height of 102 meters, required careful planning to ensure stability and safety during the erection process.

Site Logistics: Coordinating crane erection, operation, and removal within an active construction site demanded meticulous logistical planning to minimize disruptions and maximize efficiency.

Solution:

To address the challenges presented by the project, the construction team strategically chose and erected a combination of tower cranes.

Terex CTL 140s: Five Terex CTL 140 tower cranes were erected across the three blocks. These 10-tonne luffing cranes with high luffing speeds provided the necessary lifting capacity and flexibility for the diverse construction needs. They were installed at heights of up to 66 meters, allowing them to efficiently cover various floors within the buildings.

Moritsch RTM280 Freestanding Crane: For the tallest residential block, a Moritsch RTM280 freestanding crane was chosen due to its impressive height and lifting capacity capabilities. With a height of 102 meters, a 45-meter jib, and a maximum capacity of 12 tonnes, this crane was well-suited for the unique requirements of the highest building.

Execution:

Terex CTL 140s: The Terex CTL 140 cranes were erected on each block using standard tower crane erection procedures. Their flexibility in height and luffing capabilities allowed them to efficiently serve different floors of the buildings during construction.

Moritsch RTM280 Freestanding Crane: Erecting the Moritsch RTM280 freestanding crane at 102 meters required a saddle crane approach. This method allowed for the safe and controlled erection of the crane to its full height. The crane was equipped with a 45-meter jib, providing extensive coverage across the construction site.

Logistics and Removal:

The coordination of crane installations and removals was a critical aspect of the project:

The Moritsch RTM280 freestanding crane was erected using a saddle crane and carefully positioned to ensure stability at its towering height.

To remove the Moritsch RTM280 after project completion, a road closure was arranged. A Liebherr LTM 1000 mobile crane was employed to dismantle and remove the crane safely.

Outcome:

The strategic selection and careful installation of tower cranes enabled the successful completion of the Park Royal Residential Development. The Terex CTL 140s provided efficient lifting solutions for the varied heights of the blocks, while the Moritsch RTM280 freestanding crane met the unique demands of the tallest residential building. The project's completion within the planned timeframe demonstrated effective project management and engineering prowess.

Lessons Learned:

Tailored Solutions: Different building heights necessitate crane selection tailored to each block's requirements.

Safety First: Erection of tall freestanding cranes requires careful planning to ensure stability and safety.

Logistical Planning: Coordinating crane installations and removals within an active construction site demands meticulous logistical planning.

In Conclusion:

The successful completion of the Park Royal Residential Development's tower crane project showcased the effectiveness of careful planning, strategic crane selection, and precise execution. The team's ability to address challenges related to diverse heights and unique crane requirements demonstrated their expertise in the field of residential construction.
