The construction of any structure, be it a bridge or a tank, requires elaborate processes involving many steps. Formwork is an essential part of the construction process. With a wide range of technological advancements, the construction industry is constantly evolving. From the introduction of new methods for the construction of various structures to developing and using machines that greatly reduce the risk factor, the industry has reached new heights. The use of formwork for the concrete slab and lifting heavy equipment has generated a great demand in the construction industry.
The first question to ask is, what is formwork? Formwork is a temporary structure that can support a part or even the whole of a permanent structure until it can support itself. The components are assembled to form the temporary structure. One of the most common methods of keeping the formwork in place is a supportive scaffold system. Sometimes heavy lifting equipment is used in place of scaffolding. Bygging Uddemann has the most comprehensive systems in the business for formwork construction. Our efficient systems are suitable for all kinds of heavy loads whose placing, removal and transport require a high degree of precision.
Requirements of Good Formwork
The use of concrete formwork has become a common practice among leading construction companies worldwide. Construction projects that require formwork include roof and steel structures, bridges, bridge sections, and concrete slabs. Good formwork should satisfy all the following requirements listed below:
- Should be sturdy and durable to withstand all kinds of dead loads
- Should be braced efficiently and propped horizontally and vertically, to retain shape
- The joints in the formwork should prevent leakage of cement grout
- Should allow for removal of various parts in desired sequences without concrete damage
- The formwork material should be affordable, suitable for reuse and easily available
- It should be as light as possible and accurate set to the desired line
- It should rest on a firm base and be levelled on a plane surface
- The formwork material should be able to withstand exposure to high temperatures
- Should have superior workmanship and frequent inspections
Types of formwork used in concrete construction
The types of formwork systems that can be used for the construction of a concrete slab mainly depends upon important factors: the type of the structure and the material to be used. The different types of materials that can be used are timber, steel, aluminium, plastic, and concrete. Some of the different types of formwork are beam formwork, column formwork, slab formwork and concrete formwork to name a few.
Concrete formwork is one of the most preferred options in modern construction. This is because concrete is a virtually indestructible material when reinforced, making it the perfect choice for major construction projects, and even complex, detailed structures. When it comes to formwork, construction businesses should select the type most suited to the structure to be built. While there are many formwork systems available such as cassette, climbing, flexible, slipform and horizontal formwork, the last option is a commonly used one.
As mentioned earlier, businesses can choose from a myriad of options when it comes to formwork materials. However, the smaller, lighter horizontal formwork system uses aluminium, steel, and fibreglass. It consists of a series of preformed interconnected falsework bay and decking panels that are generally used in the construction of slabs. Being a lighter and safer option, this system is more ideal compared to traditional options.

Construction companies utilize various types of heavy lifting equipment to carry out activities such as lifting and lowering of formwork structures, heavy machinery, as well as erecting buildings. With technological advancements in the construction industry, several kinds of lifting equipment are now available on the market. Having designed the most comprehensive systems in the business, we have found that the hydraulic pumps, climbers and jacks in our heavy lifting systems work well. They are used for placement, removal or shifting of heavy loads that require a high degree of accuracy, precision and safety.
We supply hydraulic devices for slipforming, heavy lifting and transportation, and steel tank construction. This equipment comes with hydraulic pumps and motors to conduct efficient and effective operations.
How Does a Hydraulic Pump Work?
We develop, manufacture and test hydraulic pump systems that can withstand harsh working environments around the globe. Such high-pressure hydraulic pumps are designed to operate 24 hours a day from high temperatures in the equatorial region to freezing temperatures in the Nordic region. So how do hydraulic pumps work?
Let’s start with the basics. Hydraulic slipform construction methods and heavy lifting equipment require hydraulic pumps and accessories. In the simplest terms, a hydraulic pump is a mechanical device that converts mechanical power into hydraulic energy. Here is a closer look at the mechanism used in a hydraulic pump. It generates flow with power that is sufficient to overcome any pressure induced by the load. The operation of a hydraulic pump comprises two fundamental functions: firstly, the mechanical action creates a vacuum at the pump inlet. This, in turn, allows atmospheric pressure to force liquid into the pump’s inlet line. Secondly, the mechanical action delivers this liquid to the pump outlet and then forces it into the hydraulic system.
Hydraulic Pumps and Motors: Components
Due to their various uses and mechanisms, there are several classifications of hydraulic pumps: clutch, gear, piston, rotary, fixed and variable displacement pumps, etc. We supply hydraulic power packs that are high-pressure hydraulic pumps with various capacities with hydraulic lines. The pump units range from different capacities to motor size and working pressure.
Listed below are the main components of our hydraulic pumps:
- Hydraulic system
- Electric motor
- Oil pump
- Oil reservoir
- Operating valve
- Ball valve
- Filter cartridge
- Pressure gauge
- Pressure guided return valve
- Return line oil filter
Now that we have a fair idea about the working and components of hydraulic pumps, let’s understand what goes into their maintenance, upkeep and repair.
Hydraulic Pump Maintenance
The lack of maintenance of hydraulic systems is the leading cause of system and component failure. Hence, it is important to understand the proper maintenance techniques of a hydraulic pump system. This includes preventative maintenance as well as corrective maintenance.
Listed below are some basic maintenance procedures and protocols to be followed:
- Identify the hydraulic system’s operating conditions (24/7, hot/cold environment or maximum flow and pressure)
- Understand the requirements and operating parameters for preventive maintenance and hydraulic fluid
- Check the level of hydraulic fluid inside the pump
- Check the hydraulic system for leaks
- Change the hydraulic filters and filter the hydraulic fluid
- Clean the inside and outside of the hydraulic reservoir
- Check and record the hydraulic pressure and pump flow
Regular maintenance of hydraulic pumps and motors will ensure maximum output and greater longevity. For electric hydraulic pumps and accessories, it is essential to opt for a company that is well-stocked with products and has a credible reputation for after-sales maintenance of spare parts. At Bygging Uddemann, we have designed and manufactured hydraulic controlled heavy lifting equipment like hydraulic pumps, climbers and jacks for over fifty years and our equipment is still in use around the world.

The caisson construction industry is constantly evolving. Companies are using new and better methods for making the construction process more efficient and faster. However, in despite of this scenario, no matter how advanced technology gets, companies do stick to old and proven methods of construction. One such method is the gantry supported slipform technique for caisson construction.
The Gantry Slipform system can be executed in different set ups; on shore fixed gantry slipform, on shore mobile gantry slipform, off shore gantry slipform on floating dock, offshore fixed gantry slipform etc.
In simpler terms, a caisson is a watertight retaining structure that functions as a bridge pier. A caisson foundation also known as pier foundation is mainly used in construction dams as well as in ship repairs. This supplementary is a hollow box or cylinder that is sunk into the ground to the desired. It is then filled with concrete for forming a strong foundation.
A typical caisson launching is done for the following reasons:
- Simplifies the penetration of piles when there are large boulders in the soil
- Enables extension of a massive substructure for providing better resistance against destructive forces
- When the foundation is a large lateral load
- Cases when the river and seawater levels are extremely high
- When the load compositions include river forces
- Acts very well as an end-to-end carrier
- Controls the rigorous inflow of groundwater
To know this method of construction in detail, let’s have a look at the types of caissons used by companies.
Types of caisson foundation
The process of caisson foundation construction can be done using multiple types of caisson foundations. The list of these types include:
Box caissons are the type that is open at the top and closed at the bottom. The built on land, transported to the site through floating and sunk in positions. While sinking this type, concrete, water, or sand is filled in it. It is mostly used for hard strata and is available at shallow depth.
These types of caissons are used on excavation sites. The full use of these types of caissons is only done when the need to build a strong foundation on an excavation site is quite high. Excavation caissons are cylindrical in shape and are filled with concrete when they need to be used.
This type of caisson foundation is primarily used at ports and harbors. The floating caissons are prefabricated floating docks that have cylindrical cavities in them. This type of caisson foundation plays a great role in facilitating the expansion of existing maritime facilities by constructing new and improved forms of commuting.
Open caissons are box structures that open at both, the top and the bottom. This caisson is most useful when there is no firm ground support available at a higher depth. As a result, they are used on sandy soils and soft bearing stratum.
These large cylinders or boxes are mainly used for underwater construction. It is suitable for carrying out work up till 12 m of depth underwater. It is also made of timber, concrete, or steel. The compressed air used in the construction pneumatic caissons helps in carrying out the foundation work in a dry space.
Caisson construction process
The process of caisson construction does not happen at the worksite. There is a whole process that goes into that takes place in the following stages:
- Deciding which caisson type will suit which location
- Accordingly, fabricate it taking every requirement into consideration
- Transported the caisson to the actual location
- Get in the water fix it the caisson base at the required depth
Caisson construction has been in the industry since long enough now and Bygging Uddemann has been an esteemed provider of this service.

The construction industry uses a range of methods and different techniques to build a variety of structures. As a part of this system, the slip form method is one of the techniques that a lot of construction companies are using.
This method of construction is primarily known to be a valuable alternative to the conventional formwork technique. It’s specialty is that it is a non-stop method as it allows vertical and horizontal construction simultaneously. In the slip form technique, concrete is continuously poured in the formwork.
Depending on the requirements of construction companies, listed below are some of the varieties in which companies can use this method of construction.
Types of Slipform Method For Construction
Every company’s requirement for building a structure is varied. Hence, depending on the process followed by each of them, there are certain t
As the name suggests, traditional slipforming is the type where the slip from enables efficient pouring of concrete in the formwork without any hindrance whatsoever. This method is ideal for building rise buildings, towers, domes, and other such similar structures. There is often a requirement of using cranes to lift concrete materials, jacks and other materials. The functionality of this method produces high durability concrete in general. The unique ‘mix and move’ feature built into volumetric vehicles gives complete control over the consistency of the concrete thus giving the desired results.
Slipforming for mass production
Slipforming for mass production is one of the less common slip form techniques, but on the other hand, the most effective for repeated structures. Mass production slipform-setups uses a gantry system. The Gantry Slipform system can be executed in different set ups; on shore fixed gantry slipform, on shore mobile gantry slipform, off shore gantry slipform on floating dock, off shore fixed gantry slipform etc.
Slipforming for conical structures
Slipforming of conical structures or conical slipforming is another highly used method.
The way this technique functions is similar to the traditional slipforming. The only difference is that there is a change in cross section diameter lengths with the variation in height of the structure being built. This change leads to attaining the desired shape of the structure that is the conical shape. Besides the cross sections, the wall thickness may or may not vary depending on the structure’s height, material used, cone size, etc. Conical slip forming is used for building smoke outlets in factories, chimneys etc with the help of slipform concrete.
Slipform formwork of every construction company is different. Since the requirements of the structure are different the need for customised slipforms is quite high in most cases. When the traditional, conventional slipform doesn’t seem to work, this new form of slipform is used by companies and it gives the required results.
Slipform in construction is not the most highly used technique, but when it is used, companies can surely see the difference and not deny its advantages!
