A Brief Synopsys of Slipform Construction Method


Construction of high rise structures is a complex and tedious process that involves numerous interlinked factors. Slipforming is one of the best ways by which such complex structures can be efficiently built. The following article provides more information on this subject.


Slipforming is a construction method that involves continuous outpouring of concrete along a pre-set form along the walls other surfaces of a structure (Bright Hub Engineering, A NON-STOP METHOD FOR BUILDING CONCRETE STRUCTURES, 2016). Slipform construction technique has become highly popular in the last couple of decades, especially when the number of high rise buildings is increasing. This method utilizes the fast settling properties of concrete as a basic parameter. This method usually consists of two types: vertical and horizontal slipforming. The vertical type is used to build towers, high rise buildings, building cores and other similar structures. The horizontal slipforming method is mainly used to build bridges and roadways. There are several subtypes of this method such as conical slipforming, standard slipforming, gantry slipforming, etc. The following points explain more about the slipform construction method.

Advantages of Slipforming

1. This method can achieve high production rates using careful planning and work precision

2. Usage of cranes and other objects is minimized, hence being economical

3. Minimum requirement of workforce as compared to other construction methods

4. Achieving greater flexibility while building structures

Types of Structures Built

Chimneys, silos, towers, domes, etc. are popular types of constructions done with the help of slipform construction techniques. To make these structures, the pouring of concrete is usually done in a continuous and non-stop manner so that all voids, discontinuities and joints can be properly filled in, thus imparting strength to the structure. Slipforming technique is best suitable for building the central cores of buildings, which are also called as service cores. These cores are manly used for operating systems such as elevator shafts, public restrooms, ventilation processes, electrical connectivity, utility pipes, etc. Now, the central cores are sections that need to be least modified in a high-rise building. As slipforming makes it possible to make a structure that requires minimum modifications, making the building cores from is considered to be a good application. Conical slipforming is one type that is quite suitable for making such sections.

Being Economical

As slipform construction has a repetitive pattern, one does not need to dismantle or reinstall separate building parts again during structure renovation. Whatever changes that needs to be made can be done at particular elevations, without altering the original structure. A lot of money needed for renovations can be saved in this regard. Another way by which this method turns out to be economical is via saving time, saving manpower, reducing material usage, etc.

Before building buildings with slipforming techniques, there are some factors that need to be considered and implemented by businesses. These include budget allocation, keeping expert supervision, providing appropriate training to employees, and many more.
