Yaniv Engineering Company carried out the project of building offices for the “PROFIT” insurance company in Petah Tikva.
The building is a public four floors office building. The project was carried out on the second floor with a total area of 3500 square meters and 700 square meters of balcony.
The floor was designed to be a banquet hall, but a change of designation was made and the floor was adapted to an office complex with 197 offices, public areas such as main lobby, cafeteria, training rooms, meeting rooms and executive offices.
In this project, we faced several challenges:
- The engineering challenge – when we started, the height of the floor was 5.40 meters (due to the original planning of the floor to be used as a banquet hall). It was required to lower the height of the floor to 3 meters in the office area and to 4 – 4.70 meters in the public areas due to the adaptation of the building for offices, and due to the engineering requirements resulting from it such as adaptation of life-saving systems, and because of the acoustic requirements.
For this purpose, we have raised the floor with two layers with a total thickness of 15-27 cm in a variety of ways that provide a solution to the allowed fixed load limit in the floor, which has changed between the areas on the floor. The solutions that were implemented are listed below:
- Light Concrete casting.
- B30 Concrete casting with high sinking.
- Ribbed slab casting with f15 polystyrene blocks.
In addition, as part of our creative engineering solution, we created two layers of ceiling on various levels and heights, in order to reach the final required height while leaving room for infrastructures and systems and maintaining the planning according to the requirements of the project consultants and architects.
- The first acoustic ceiling in a height of 100 cm from the concrete ceiling using steel construction that was built to carry the weight of all the floor systems and infrastructures.
- The second architectural ceiling was lowered at varying heights of 70 – 140 cm from the first ceiling in which all floor systems and infrastructures are passed.
In practice, we reduced the height of the floor from 5.40 meters to 3 – 4.7 meters by raising the floor on one side and lowering the ceiling on the other side.
- Execution times challenge – meeting intensive and short time schedule. The duration of the project was set to 4 months. Detailed planning and detailed schedule and thinking was required, while during the work a meticulous control of meeting the timetable was implemented. We adapt the timetable to the actual work progress while the bottlenecks that were discovered during the execution process received immediate solution and response.
The architectural design and the complex finishing materials that were implemented in the project required us to carry out activities step by step and not in parallel, a fact that obliged us even more to meet the timetable we had planned at the beginning of the project.
We used large quantities of industrial components such as partitions (about 4,500 square meters), ceilings (3500 square meters) and more, In order to meet the defined timetable. We employed a number of plaster contractors who worked in parallel. This action required careful coordination and synchronization between the contractors. All this in order to meet the defined timetable without delaying the end of the project.
- The architectural challenge – the project includes many diverse architectural elements that required a professional and accurate finishing without compromising on quality, such as:
Ceilings of different heights and types:
- Acoustic tiles ceiling type Acofon Advantage.
- Exposed concrete ceiling covered with Sonex acoustic tiles.
- Black Heraklite ceiling.
- Wooden tiles ceiling.
- Covering ceiling made of wood panels with birch veneer finishing.
- Plaster ceiling covered with acoustic foam tiles.
- Grid tiles ceiling and plaster ceiling painted in black.
Walls cladding with 3D decorative plaster tiles in a size of 60/60 cm manufactured by Barkai Systems.
Yaniv Engineering has allocated all the necessary resources in order to achieve the optimal result both in quality of performance and in meeting the timetable. In terms of personnel, a project manager was employed and he was present at the site during the entire period of the work, in addition to a supervisor who was in charge of the engineering aspect and another supervisor who was responsible for the logistical and safety aspects.
The company’s executive director and the CEO participated in all of the weekly meetings and helped to shorten the timetable and to release bottlenecks that arose during the work.
