Each project is different from the other in some way. To be successful, you must have plenty of techniques in your arsenal. One that is good for constructing repetitive structures is known as the Tunnel Formwork System.
This system is approximately 50 years old that combines accuracy and speed to help in building complex structures in less time. Before you think of its applications, let’s first understand the basics.
What Is The Tunnel Formwork System?
This system uses multiple cell-like structures to create the finished product. The modules come in half-units of L-shaped structures. These are put together to make a rectangular base. It has wheels to support the movement. Concrete is used to put it all together. This type of system eliminates the use of plastering.
Suitable Usage
As discussed earlier, this system is perfect to construct repeating structures. Some examples are hotels and residential blocks. The same cell structure is repeated throughout. This helps with both the speed of construction and the overall strength of the building. Hive structures like these are proven to be more structurally sound than others. This job is made easier by using the right tools.
The Casting Process
- After the foundation, wall reinforcements (made beforehand) are placed at intervals using a crane in the desired area. Do not worry if you do not have a crane. You can get heavy machinery like this by using construction equipment renting services.
- The L-shaped structures are lowered one by one. They are placed next to the wall for reinforcements. These connect to form the cell.
- The wall concrete is poured between the spaces of the adjoining cell structures.
- The slabs are fixed, and heaters are placed inside. These provide the temperature required by the concrete to attain its strength. It is usually an overnight process.
- The next day, concrete is checked, and then the tunnel forms are removed from the structure.
- This is repeated till the desired number of rooms is achieved.
Advantages
- The main advantage is the savings in two of the most valued assets; time & money. The Tunnel Formwork System has proven to provide 15% cost savings. The overnight factor saves time (up to 25%).
- The structure of the building makes it extremely resistant to earthquakes. This is key in areas that experience constant seismic activities. Benefits like this are why it is important to always update your strategies.
- A well-finished building can be achieved with relatively less time and effort. Due to the procedure, it requires less labor to complete the job.
Disadvantages
- The labor required might be less, but the ones needed should be skilled because the process is different from the traditional method.
- This style of construction is not suitable for small-scale projects.
- The involvement of pre-constructed modules, heavy machinery, and skilled labor means that this method requires a big budget.
Processes like these are effective when used properly. The right type of client will surely benefit from the quick and even construction. Since you are updated with this, also keep an eye on the next big thing in construction: Repurposing Buildings.
