Bygging-Uddemann has the most comprehensive systems in the business for lifting of roof structures. The roof is one of the most crucial parts of a structure. It is placed on the top of a building but it no less than a strong base/foundation of it. Without roof structures, buildings, houses, and other such structures are incomplete.
The process of building roofs is quite a complex process. To build it in the most accurate manner and to be very sure of its quality, some of the main components that should be looked after are, ridge, rafter, joist, bolts, fascia, soffit, wall plate, and strong walls. Having these elements of the structure in place makes the process of building structure easy and quick.
Depending on the roof type one of looking for, mentioned below are some of the common yet main roof types provided roof structure service providers.
As the name suggests itself, flat roofs are the most common type of roof when building a stand-alone home. The appearance of it is extremely fancy and elite. They are typically built to stop rainwater pooling. The people who live in regions that face heavy rainfalls can make use of this roof type.
Curved roofs appear to be half-circles roof structures in nature. They are considered to be in high demand as the structure looks royal with this type of roof. The metal used to build this roof is usually copper or zinc. They increase the visual interest of the structure.
Panellised roofs are highly recommended for simple-shaped structures. They save a lot of fitting costs as well as the additional fitting work that comes along. Due to its simple structure, the process of erecting it is fast and speedy as compared to other types of roos structure.
Trussed roofs are mainly made of timber. They are said to be inexpensive as the timber sections with which it is made are less. The material used to create is light hence the whole roof structure is lightweight. Simple roof designs are best created because of this type.
Considering the condition in which our planet is in, most of the providers of the roof structure for construction suggest green roofs. The roof is just like what it sounds. The roof structure is flat in nature and has green plants placed on it. It is highly recommended because it absorbs rainwater and also provides a considerable degree of insulation.
Traditional roofs are the most common type of roof any structure can adapt to. This type is the safest option when there are budget constraints, the need for creativity is not high as well when one is looking quick building. Also, traditional roofs can easily be customized if and when changes are required.Continue reading →

Formwork is a temporary structure that supports part or the whole of a permanent structure until it is self-supporting. Once assembled the components form the temporary structure. The most common method of keeping the formwork in place during casting is to use a supporting scaffold system. When scaffolding cannot be used, lifting equipment can be used instead. Bygging-Uddemann has the most comprehensive systems in the business for this kind of works. Our systems are suitable for practically all kinds of heavy loads whose placing or removal require a high degree of precision.
As construction methods evolve, the use of lifted formwork / formwork for heavy lifting equipment has become common among the leading construction companies in the world. Generally, strand climbers and hydraulic steel rod climbers are used for lifting and lowering of formwork. Construction projects requiring formwork are lifting of roof and steel structures, cranes, bridges, bridge sections and more.
Let’s learn more about formwork for heavy lifting equipment, the material types and requirements for a good formwork.
Types of formwork materials
Many different kinds of concrete formwork are used in construction. The type of formwork system used for construction largely depends on important factors such as the types of the structure to be built, as well as the material to be used. Some of the different types of well-known formwork are slab formwork, column formwork, beam formwork and more.
Timber and plywood are used in traditional timber formwork to form the pouring moulds. While this method is cheaper, it isn’t as effective because wood is not as strong and durable as metal or steel. The timber should be lightweight, well-seasoned, easily workable with nails, as well as free from loose knots. Still, complicated sections of buildings requiring great attention to detail, utilize timber formwork.
Engineered formwork: steel, aluminium & plastic
Generally, prefabricated moulds made from metal frames of steel or aluminium are used in engineered formwork systems. It is cheaper and quicker to use than traditional formwork. The added benefit is that these frames are extremely cost-effective, strong and durable, and rarely need replacement. The construction of engineered formwork is faster and requires less manpower, saving time and money. Simple structures can be built with reusable plastic formwork systems, consisting of interlocking, lightweight and strong systems.
Stay-in-place formwork is used for supporting parts of a structure. This type of formwork consists of insulating concrete forms that are filled with reinforced concrete and are left in place once they are set.
Last but not least, concrete formwork is what is mostly used in modern construction. Although there are different types of formwork available today, concrete is the preferred option. When reinforced, concrete is a virtually indestructible material, making it the perfect choice for major construction projects, as well as small, complex and detailed structures.
Formwork construction should be efficient enough to be able to retain its original shape. When it comes to formwork, construction businesses should be able to select the type most suited to the structure to be built. While there are many formwork systems available for use today such as beam, column, plastic, slip form, cassette, climbing, flexible and horizontal formwork, the last option is found to be the most widely used.
Requirements of a good formwork
Good formwork should satisfy all the following requirements listed below:
- Should be strong enough to withstand all kinds of dead and live loads
- Should be efficiently braced and propped both horizontally and vertically, to retain its shape
- The joints in the formwork should be able to prevent cement grout leakage
- Construction of formwork should permit removal of various parts in desired sequences without concrete damage
- The material of the formwork should be easily available, affordable and suitable for reuse
- It should be set accurately to the desired line
- It should be as light as possible with reusable material
- The formwork material should not warp or get distorted when exposed to the elements.
- It should rest on a firm base and be levelled on a plane surface
- Must have high-quality workmanship and regularly scheduled inspections

The number of techniques being used in the construction industry is only increasing. The industry as a whole is constantly making an effort in using equipment that makes the process of construction easier as well as faster. One such equipment that assists companies in carrying out various processes of construction is a skidding system.
Skidding systems are ideal for moving industrial objects and installation irrespective of the size and weight to various locations. For many tasks, they are a much more safe and effective solution than cranes. Due to its user-friendliness, the business of hydraulic skidding system providers is on a rise as more and more companies are making use of it.
How Does a Skidding System Work?
Construction companies happen to undertake processes that involve carrying heavy loads from one location to another. This is where skidding systems play a major role. A skidding system is designed in a way to carry out safe and precise movements of heavy materials. The main attribute of this system is that it can move materials and structures even in confined and restricted environments.
Essentially, the equipment consists of jacks (for pushing & lifting) sitting on a base plate. The base plate has low friction pads attached underneath for sliding on the transfer lane’s steel track. Each unit is small, but with large lifting power and linked with several units, enormous lifting forces can be achieved. Skidding systems have the capability of carrying out a wide range of functionalities since they have the option of combining several units to create the most suitable system for moving complex loads.
Features of Hydraulic Skidding System
It is certainly true that construction equipment is structured in the form to make processes easier to conduct. Just like that, a hydraulic skidding system also has a list of characteristics that it is made of. Listed below are some of the exceptional features that differentiate it from other equipment.
Ability to Move Extremely Heavy Loads
Low Maintenance Cost
No external force required
Safe gripper release
Types of Skidding System
There are primarily two types of skidding systems that companies make use of. The model is classified into Heavy Track and Low profile. Both the systems are equally safe and proficient in moving heavy loads, but depending upon the application of the particular model, companies can make a choice.
Heavy Track Skidding System – These systems are made for more rough use. They can be best used on field conditions or tracks that are a span of unsupported distances. Heavy track models can be used for loads from railcars to transporters, or across open areas or on uneven ground.
Low Profile Skidding System – Low profile models are designed for moving loads where there is restricted access or overhead clearance and good surface conditions, like well-supported surfaces. All components of this system are hand-portable and easy to transport.Continue reading →

With a myriad of technological advancements, the construction industry is continually evolving. From introducing new methods for construction of different structures to developing and utilizing machines that greatly reduce the risk factor, this industry has reached heights never thought possible before. The use of formwork for lifting heavy equipment is one such discovery that has generated a great demand in the construction industry nowadays.
What is Formwork?
Typically formwork is temporary or permanent molds into which materials such as concrete or other similar materials are poured. When it comes to concrete construction, the shuttering moulds are supported by the falsework supports the shuttering molds. Concrete is now universally considered to be the most suitable material for construction, due to which its use in the construction of bridges, buildings, other structures has risen tremendously. There are multiple benefits of opting for concrete as compared to other materials. Some of them include its useful capability of withstanding high temperatures that ensure protection against fires. Hence a formwork system is ideal for construction. The system is used to hold and store wet concrete until an important construction process called curing is completed.
What are the Different Kinds of Formwork?
The type of formwork system that can be used for construction largely depends on important factors such as the types of the structure as well as the material to be used. Some of the different types of formwork are called slab formwork, column formwork, beam formwork and more. Formwork for lifting heavy equipment must possess the following characteristics:
- It should be sturdy, light and durable
- It should be able to rest on a firm base
- It should be able to withstand extremely high temperatures
It goes without saying that formwork construction should be efficient enough to retain its original shape. When it comes to formwork, construction businesses should be able to select the type most suited to the structure to be built. While there are many formwork systems available for use today such as slip form, cassette, climbing, flexible and horizontal formwork, the last option is found to be the most commonly used.
With the construction boom, new types of materials are constantly flooding the market that are cost-effective, lightweight or durable. Nowadays, businesses prefer to opt for materials such as aluminium, steel, and fibreglass. The lighter and smaller horizontal formwork system utilizes such materials for construction. It comprises a series of preformed interconnected decking panels and falsework bay that are generally used in the construction of slabs. Being a much lighter and safer option, this system is an ideal choice as compared to traditional options. Business can research and opt for reputed formwork services in Sweden that can help to reach a better and more detailed understanding of the process.Continue reading →

Det finns flera olika komplicerade faktorer vid byggandet av en bro, exempelvis kanske bron ska byggas över en trafikerad järnväg eller över vatten. Då behöver bron byggas i närheten eller vid sidan av den slutgiltiga platsen för konstruktionen och den här metoden kallas för brolansering. Efter att vissa arbetsmoment och delar av bron är färdig dras de ut till sin slutliga position och för brolansering krävs utrustning av hög kvalité som klarar extrema väderförhållanden, från kalla nordiska vintrar till varmt ökenklimat.
Så gjuter man betongen för broar
De traditionella byggteknikerna fungerar tyvärr inte på alla projekt som exempelvis vid brolansering och glidformsgjutning har blivit ett speciellt sätt att gjuta betong. Det börjar med tillverkning av en glidform på bottenplattan och sedan fylls formen på med betong och armeringsjärn. Allteftersom betongen stelnar flyttas glidformen ett steg uppåt och detta sätt är mer ekonomiskt och effektivt än de traditionella metoderna.
Konstruktioner med stöd
Beroende på byggprojekt krävs olika typer av brolansering och utrustning. Kassuner har länge använts för att underlätta arbetet och ordet kassun kommer från franskans caisson som betyder låda. Dessa är en viktig förutsättning när delar av arbetet ska utföras under vattenytan och det ska ske på ett säkert, smidigt och effektivt sätt. Vanligen byggs kassunen på plats och förflyttas sedan till rätt position under vattenytan och dagens stora kassuner väger flera hundratals ton vilket gör förflyttningen komplicerad. Det krävs kompetens och speciell utrustning för att utföra tunga lyft.
Montering och lansering av överbyggnaden
När bron befinner sig på den slutliga positionen ska den vanligtvis förses med en överbyggnad i betong och sedan beläggas med asfalt. Efter det utförs arbeten som montering av räcken och belysning.
Slutliga finslipningar och kontroller
Grunden i brolansering är att delar eller hela bron byggs vid sidan av eller i närheten av dess slutgiltiga position och sedan flytta hela eller delar av bron ut till sin rätta plats. Själva lanseringen sker när det stör trafiken så lite som möjligt, exempelvis under nattetid. Metoder för att horisontell förflyttning ska bli mer effektiv och säkrare utvecklas ständigt och en ny metod som har nått stor framgång är en kombination av tunga lyft med hydrauliska lyftare och skidding-teknik. Metoden minskar på antalet rörliga delar och istället för att använda traditionella lager används en skidding-teknik med låg friktion.
