Are precast concrete structures better? How?

It’s a known fact that precast concrete structures produce superior buildings than standard forms of concrete structures. So, what makes Precast Concrete Construction so different than other forms of constructions? After all, the concrete does not know whether it is statically reinforced or pre-tensioned (pre-stressed)! Precast concrete is prepared and cured at a location other than the construction site. But what really distinguishes precast from in-situ is it’s stress and strain response to external (load induced) and internal (autogenously volumetric changes) effects. Precast elements are of a finite size and need to be joined to the other elements of the construction to form a complete structure.

Basically, concrete is a mixture of sand, gravel and other aggregates that are usually bound together by a water based binder. Modifying agents and additives are introduced to improve the characteristics of the concrete.

Precast Concrete Construction

Precast concrete is cast under factory controlled conditions and not erected on site until it is fully hardened. Just like in-situ concrete, precast concrete can be plain, reinforced or pre-stressed concrete.

The process becomes more ‘buildable’
With precast structures, the entire process becomes easy and more ‘buildable’. This is because, the construction sequence becomes more sensible and each part is pre-built to exactly fit into place. The overall construction is safe and    there is a sense of stability too. Further, skilled labor is used for the construction of buildings using precast concrete and hence the overall quality of work is superior.

Simply more cost effective
With precast structures, the building component cost per – structural capacity is comparable to other materials and the overall cost of construction including transport, fixing finishing, maintenance and repair are competitive. There is lowest standard deviation and hence quality and final finish is assured. This method uses factory engineered concrete and hence destructive load testing and non-destructive load testing assurances are given.

Fast to erect
The precast concrete manufacturing takes some time – even several weeks. But, once ready, it greatly speeds up the on-site construction work. Clear heights, floor zones and other statistics are accurately built and it greatly speeds up the entire process.

Above all, the intrinsic qualities of an industrial product, manufactured in a controlled environment with accurate methods are bound to be superior to standard concrete mixed onsite. In a factory controlled environment, advanced quality control methods are used and hence the final finish is far better than standard concrete mix. Well, the dimensional accuracy, properties of the hardened concrete and reinforcement can all be checked before inclusion in the structure and hence the final product is more robust.

On a final note, factory made products are independent of the weather conditions on the site and are processed separately from the construction work on site. That’s why they have fewer external dependencies and external factors that negatively impact their quality.

In a world where the need for speed and quality is a never ending quest, precast concrete adds real value to a construction project and offers just the right solution for building sustainable – futuristic structures!

Modular Construction – the future of construction!

Building a home ground up – takes quite some time, even if it is an average home, it takes almost a year to complete – from conceptual design to when a home owner finally moves in.
Modular Construction goes far beyond the typical concept of construction and has created quite a revolution in the way buildings are developed. A building or home is constructed by assembling parts that are ‘manufactured’ in a highly controlled factory environment. Architectural designs are created and then repeated using the exact same materials and manufacturing standards.

With repeatable designs and construction methods, a home can be built within half the time taken for normal construction – that’s how revolutionizing this method is!

Here is why Modular Construction is going to be the future of construction!

Predictable outcome
In this type of construction, modules are created offsite and are then transported to the location of construction to be assembled into a complete structure. Since each module is built with precision and exactly the same dimensions, the outcome is predictable and you know beforehand what the final product looks like. The process is foolproof and highly repeatable and delivers the same quality every single time – removing all the guesswork of what the final product will look like!

Lower construction costs
It’s a known fact that the total cost of a new home is typically 60% of its selling price. The underlying principle is that when construction costs are high, the selling price will naturally be higher. Conversely when construction costs go down, the selling price also goes down. Modular Constructions have significantly reduced the construction costs and offers as much as 50% of savings to the end customer or buyer as opposed to homes built with traditional construction methods.

Heightened efficiency
Since Modular Construction takes place in a factory controlled environment, there is strict adherence to processes and procedure and hence the overall efficiency is high. Plus, there is no ‘environmental factors’ that create a hindrance in the processes. Workers can work 365 days of a year and round the clock and the entire process is seamless without external factors creating any glitches. Well, the repetition of the same process over and over again brings accuracy in the way people work and the overall efficiency of the entire process is heightened!

Increased onsite safety
When it comes down to safety, onsite construction requires you to take utmost precaution and ensure that your labor force is equipped with the right kind of safety gear and safety training. Further, just in case there are any accidents onsite, further construction is stalled until all the underlying issues are resolved. Since Modular Construction happens in a factory all these kinds of safety issues are significantly reduced. Bad weather, equipment malfunction and human errors could pose a greater danger onsite rather than in a highly controlled environment as in a factory.

As for the future of construction, modular buildings definitely will take over the traditional onsite construction methods!

Is modular the future of construction?

One of the most interesting developments in construction is – modular construction. The reason for its increasing popularity is its ability to shorten construction time and improve the quality and sustainability of the construction. It standardizes the construction and enables customization of the various elements too. Individual modules are constructed with great precision and are then combined to create larger structures.

Well, an Offsite Construction, whether modular or prefabricated, requires a highly detailed plan at an early stage of the project. It is however more sustainable and more efficient.

Here’s why modular construction is seen as the future of construction:

Less material waste – Since all the elements are created in a factory, it makes things easier when it comes to recycling wastes. The materials can be reused and are not discarded as opposed to ‘on-site wastes’ in conventional construction.

Less site disturbance – The usual buzz created by the workers, transport vehicles and equipment onsite is reduced as majority of the actual ‘work’ happens at a factory far away from the construction site.

Flexibility of use – the modules can be reused and recycled as per requirement. They can also be relocated, remodeled and refurbished with minimal energy.

Reduction in construction schedule – The modules are produced at the same time the site is ‘prepared’ for construction. Meaning the lead time is reduced. In turn, the completion time for the entire project is reduced by 30 to 50%.

Delays due to bad weather are reduced – with conventional construction; there are a number of delays due to bad weather. This weather delays are reduced by at least 60% to almost 90% in some cases. This is mainly because the modules are produced in a closed factory environment.

Safer environment – The factory environment is highly controlled and is definitely safer for workers as opposed to an open construction site which is susceptible to a number of work related ‘accidents’.

Built to code with quality materials – Modular buildings follow the same code as the onsite construction buildings. The materials go through a thorough quality check before they are selected for use in the modules. Only the best quality material is used to construct these modules in a factory.

Challenges of traditional construction

Traditional construction is mainly linear and requires every step to be complete before the next one can begin. Weather damage can inconsistency in the availability of labor could be some of the limiting factors of this kind of construction. Further, the construction happens out in the open, and is highly dependent on weather conditions.

The construction and infrastructure market is highly competitive and in order to provide facilities at that are fully functional – quickly, it’s vital that constructions use modular methods rather than conventional. This enables them to deliver results faster and more efficiently. Well, the quality of construction is at par with the quality of construction seen in on site – traditional means!

Most Common Uses Of Precast Structures In Construction

Good quality control, speedy construction and economy are some of the factors that make precast constructions a very popular choice. With the growing development and expansion of towns and cities, there is an increasing need for faster construction timelines without any compromise on quality and any impact on the costs too. Precast construction is one method which can be trusted and has uniform quality. Concrete is cast into a reusable mould and then cured under factory controlled environment, and transported to the construction site to be assembled with the other elements.

Precast concrete is used extensively in building structures such as floors, roofs and claddings. Some form the basic elements of a building and some are used for aesthetic appeal and decorative purposes. Here are some of the most common uses of precast structures in construction.

Use of precast concrete in frames

There are two main types of precast concrete building frames. The structural frame consists of slabs, beams and columns. These structural frames can be used to assemble entire offices, car parks as well as retail developments. The cross wall frame consists of floor slabs and solid walls. It is used for hotels, schools and hospitals.

Use of precast concrete for floors

Floors could be of different types such as a plank, hollow core, beam and block or double tee. Using the precast technology for floor construction ensures that the quality of each slab is maintained and the construction is fast. There is standardized cross section and the strength to weight ratio is exactly maintained. Since it is precast in a quality controlled environment, the finishing is good and surfaces look neat.

Use of precast concrete in cladding

Precast concrete cladding is used as a structural element. It can also be used as a non structural decorative façade. In this method, the backing concrete is made from an ordinary mix and the façade consists of a special mix. A great variety of forms and details can be casted and used for decoration. Some of the decorative precast application includes bridge beams, double Ts, hollow core slabs, pipe or culverts, foundation walls or architectural panels etc. Sometimes precast parts are used for aesthetic appeal too. Some examples are countertops, sinks and bathtubs, decorative rock features, decorative window sills, accent strips, statuary or paving stones etc.

The main advantage of the use of precast elements in this type of construction is its repeatability. It is very easy to make many copies of the same product. It is a very efficient way of creating exactly same elements from a mould and using them where repeated designs in a construction are necessary. When you use precast, you can control the quality of the final product by ensuring that each piece is built with great care and is perfect before it is transported to the construction site. The curing of the precast elements is also done in a factory by heating the precast parts and this greatly increases the strength of the structure.
