How to Choose the Perfect Formwork System: Key Features and Tips

Link to Zolo

--

Formwork has a dual function which supports the plastics and hardens the concrete till it is strong enough to support the loads imposed on it and also till it imparts a good finish to the concrete surface.

Formwork is a temporary structure which gives the desired shape to the concrete. It gives safe working areas and access ways for construction workers.

Features of Formwork

The components should be designed that cater to excessive loads that are imposed on the framework. So to achieve this formwork design should be done by an experienced person having full knowledge of the designs. It should be taken into account that designs and construction load is as per nominated by the designer.

Accuracy

Formwork should build accuracy greater than in the concrete element. Support structure should be sufficient to ensure accuracy is maintained till concrete hardens. Accuracy may affect the selection of material from which formwork is built as some materials are assembled to tighter tolerances.

Stiffness

Formwork should not sag, bulge or otherwise to the extent that the concrete falls outside the tolerances specified. The formwork designer should provide adequate details to have the required stiffness and site personnel is responsible for ensuring correct materials and adequate quality.

Water-tightness

All joints should be sealed in such a manner that there is no grout leaking from the network. Grout loss causes hydration staining and honeycombing which can affect the strength and durability of the final structure.

Permeability

High permeability formworks have a lot of advantages. There may be many systems available but e, but they may simple as a fabric material which is attached to plywood backing which contains drain holes. This formwork &#;bleeds&#; water and air to escape through the formed faces and has effects of (a) lowering the W/C ratio in the adjacent areas (b) increasing the strength permeability in these outer areas and © improving the finish.

Robustness

Formwork should be robust to withstand repeated stripping and storing. Re-use of formwork is important in improving the overall economy of the structure. The extent of possible re-use varies with formwork materials &#; with ranges from &#;up to 6 times&#; for plywood to 30&#;40 times for fibreglass and 70&#;100 times for steel.

Ease of stripping

Formwork should be easy to remove to minimise damage to the concrete and to the forms. Adequate draw (taper) on vertical faces should be considered and should therefore be given to providing and the movement which would allow east facilitation easy removal of specialist systems.

Standardisation

Formwork components should be standardised in size to avoid unnecessary cutting. They should be able to be stripped and re-erected to increase the speed of construction. It entails a system that comes apart easily has minimum elements needed to be replaced and is easily shifted with available equipment. Small jobs will require manhandling and large jobs require crane capacity to improve efficiencies.

Safety

Formwork should provide a safe working environment for all working there. It must have adequate strength but must be stable against uplift, overturning, sideways or sliding movements. The tightness of the material should be checked before work.

Selection Tips for the Perfect Formwork System

Evaluating total project needs

Consultation and professional support are required so that we can use the formwork efficiently and to its full capacity. Eliminate the unplanned cost by asking the correct questions in the evening. The first step is reviewing the project, design and site challenges. The first step to ask questions such as does the design calls for use of multiple formworks, whether room of ageing is there or not and site calls for working in close quarters.

Assessing the situation, evaluating forming systems, receiving bids, project planning, constructing the structure, and then project closeout.

Cost-effective solutions

Professional advice is needed to make a decision for choosing the formwork system. Availability of crane, access in and out and experience of labour amongst others. Formwork suppliers should be involved early on in the projects. A comprehensive evaluation should be done after taking cost considerations.

The contractor has two choices forming system that costs more but is high in productivity, has good safety features and is more reliant on a forming material that is inexpensive and labour intensive.

Value engineering of project design

Reputed formwork company will provide professional engineering services that recommend design changes for an economical project. Formwork specialists provide assembly and erection plans to suit preferences. Value engineering is helping the contractor make the right decisions about every aspect of formwork. Costs are kept in control and risk assessment is done well in advance.

Estimating total costs and scheduling

Suppliers should be called at a very early design phase. This will ensure much information in bid documents for an accurate cost estimate. Apart from actual rental or purchase costs, the estimator must take into consideration plywood not being quoted, unspoken expenses, tools, freight and labour requirements that will impact the schedule.

To Buy or Not

The decision to buy or rent a forming material should be based according to the duration, how it is used and the overall strategy of the construction company. If a formwork system has to be rented for 8&#;10 months purchasing might be a more economical one. Along with the purchase, there are additional costs of maintenance and storage. Some formwork companies also offer reconditioning services. The quality of the product must also be kept in mind while making the decision.

Jobsite plan development

An effective jobsite plan communication between all parties including the contractor and the formwork supplier is a must. All elements of the job and framework should be considered while developing a job site plan. Questions such as which elements are to be constructed first, what is the order of use, can the formwork supplier preassemble?

Details such as material delivery and formwork assembly should be aligned. The trucks loaded for delivery are stage in an appropriate manner so that assembly can begin as soon as the first truck comes. Apart from formwork panels connecting hardware is required for erection. When properly organised as soon as the material is unloaded it can be put to use.

Equipment and Returns management

Performance is boosted. The formwork delivery should be timed in a manner that it is present wherever required. Delivery of removal should also be well planned in case there is less storage on site.

So, picking just the right formwork syste­m is key for a construction project&#;s win. If you zero in on ke­y traits like how strong it is, how easy to use, and how fle­xible, your chosen system will match your proje­ct needs. Plus, consider ne­w ideas like plastic shuttering pane­ls. They offer big perks like­ being lightweight, reusable­, and very efficient.

Summary

Whether it&#;s better for a company to rent or purchase formwork items and systems depends on the kind of project under development and the time it will take to complete. Either way, the supplies needed must be of high quality and durability to ensure the timely, accident-free completion of the work. This means that your formwork provider should be a professional who has the requisite capacity to meet a project&#;s needs, as well as the technical know-how to customize options and deliver.

Therefore, it is advisable that you watch out for suppliers with a limited product range. Often they will cut prices on standard-forming jobs but will have to quit when it comes to the more challenging part where know-how is needed. By contrast, a more experienced provider with an extensive range can supply custom-made forms.

Ultimately, it pays to only buy or rent from established companies with extensive experience. Ensure that the company you select offers professional and on-time design, with the technical capabilities to provide support to your engineering teams. You should be wary of formwork companies that offer discounted rates as they tend to use counterfeit products. Moreover, they do not maintain equipment to the best standards. This fails to provide the safety and peace of mind that you need to ensure quality work on your project.

In this report, we highlight what you should look out for when choosing a formwork provider for your construction needs.

5 THINGS YOU NEED TO KNOW WHEN CHOOSING YOUR FORMWORK PROVIDER

When it comes to choosing your formwork provider, you cannot afford to make your decision too quickly. There are specific things that you need to look for when purchasing or hiring formwork systems. The correct formwork can make a construction project a success, whereas using the wrong systems can literally bring down a building.

Formwork makes up about 1.2% of the total costs of a building&#;s structural work. But you would be incorrect in thinking the role it plays is simple and insignificant. In fact, choosing good quality from a reliable provider is one of the most important decisions you&#;ll make for your project.

Here are five things you need to look for when selecting a formwork provider for your next construction project.

1. Safety and quality

It goes without saying that safety and quality are of the utmost importance with any type of formwork or scaffolding. That&#;s why you should look for a provider who is committed to the following:

• Meets certification: Devastating accidents can happen when forms are removed too soon before the building material has set. Equally, poor and under-designed formwork can bend or even break during the filling process because it does not meet certification.
  Make sure your supplier and their products meet the necessary safety standards set by your country or region for construction work and products. It pays to familiarize yourself with the certificates required, and cross-check if your formwork provider has them.
• Cares about quality: You must consider your provider&#;s product in the decision-making process.
  For example, steel-framed wall formwork with standard plywood facing requires more maintenance and repair than a hot-dipped galvanized steel frame that uses specially manufactured plywood designed for longer life.
• Meets maintenance standards: Before deciding on your formwork provider, you need to ensure that they thoroughly inspect and test their hire equipment to guarantee the strength and quality of each piece.
  You will be surprised to find out that not many companies invest in the meticulous upkeep and maintenance of their hire equipment.
• Does not use counterfeit materials: The use of counterfeit products is a major cause of accidents on project sites. That&#;s why it&#;s important to know the difference between a genuine product that can bear your required workload.
  Sourcing from an inexperienced or questionable formwork provider means that you may receive a faulty product, which can have dangerous consequences. It helps to know that the Middle East is a major market for counterfeit products due to the high number of imports and exports in the region.One way you can identify counterfeit formwork products is if the discount is too good to be true. Products certified by the manufacturer will not be available at steep discounts, whereas counterfeit items, which use inferior materials, can offer a lower price point, but it comes with the potential for catastrophic consequences.
• Enjoys good industry reputation: A formwork provider who has repeat business and customer recommendations will also have a market reputation for safety and quality.

2. Value for money

The simple truth is that quality formwork systems do not have to be exorbitantly expensive. In designing and building formwork, you should aim for maximum economy, which you can do by focusing on the following points:

• Clever design can contribute greatly to the overall costs. Find a form provider who can offer expert engineering and technical support to projects of all shapes and sizes.
  The formwork should be well-priced, with systems that are durable, reusable, and quick to erect. Well-engineered formwork will give your project enhanced productivity whilst reducing expense.
• Your formwork provider should offer updated systems to help you reduce, or ideally altogether remove, the need for conventional formwork like timber and plywood.
  More old-fashioned kinds of formwork have more wastage and are typically designed as single-use.  Using a modern, more up-to-date system is better for your project&#;s bottom-line and the environment.
• Be wary of huge price differentials. Expanding on the point above, as a buyer you need to be conscious of how products should be priced so that you can understand when you are getting a cost-effective solution versus a suspect, possibly counterfeit, product.
  If the product is more than 20% cheaper than other systems, that should raise some red flags. More likely than not, heavily discounted products are counterfeit and could be ineffective, or possibly dangerous.

3. Experience

Look for someone with proven formwork experience across a variety of sectors. The following factors will help you determine if a possible provider has the experience you need for your project.

• Market reputation: Reputations are built through repeat success, over several different kinds of projects.
  Not all projects are the same, and you want a provider with a commitment to service excellence and a &#;can-do&#; approach, no matter the type of project.
• Low accident rate: Whilst it may not be possible to find a formwork provider with absolutely no accidents in their entire history, you should look for someone with the least number of incidents.
  Ensure that the formwork they provide is strong and well-maintained and can work across all weathers &#; especially bear the expansion and contraction that comes from extreme heat and cold.
• Local industry familiarity: Sourcing someone who has worked in the local market means that they are familiar with the nuances of climate constraints, logistics support, as well as local workforce idiosyncrasies. It also gives them the added advantage of responding quickly and with flexibility.
• Credit history: It&#;s an industry fact that the formwork and scaffolding sector continues to grapple with payment challenges, especially with the pandemic disrupting all industries.
  As a customer looking to hire modular support, it is better to use caution and choose a company with a reliable credit history. A formwork provider who is caught between payment cycles will be strapped for cash and may fall behind on material upkeep.

4. Ease of assembly

Formwork systems should be quick and easy to erect and dismantle and have the following attributes:

• Scalability: Finding a local formwork provider means that, in addition to being able to respond quickly to your need to scale scaffolding or modular formwork up or down, they can also quickly recycle panels, beams, and features.
  Sourcing from a smart provider who has provisions means that vertical formwork products with fewer components than traditional econo-form panels have the added advantage of saving you time and effort on shutter assembly.
• Customizable solutions: A formwork company needs to be able to identify each project&#;s needs and develop an appropriate solution. You should choose a provider who can customize existing modular structures to suit your specific requirements. Some projects may require a self-climbing system, for example, and your formwork supplier needs to be able to provide such solutions.

5. Capacity and deliverables

Make sure your formwork supplier has sufficient product and capacity by examining these elements.

• Resources: It is imperative that your formwork provider has adequate manpower (including labor if required) and the technical expertise to do the job well.
  To determine the most efficient solution for a project, a contractor will evaluate several options to optimize resource utilization. Among the other considerations, the choice of formwork and how it is applied is of prime importance.
• Network: It also helps if a formwork company has multiple branches across cities, especially near your project sites. This gives you added coverage to ensure the timely supply and wide distribution of products and services.
• Consumables: If your formwork provider sells a range of handy formwork consumables, like tie cases, slab and wall separators, steel wool, and molding agents, among others, it is an added advantage as they can function as a one-stop-shop for your formwork needs and advice.
• Timeliness: During the construction process, the concrete formwork has a very central role to play in the construction timelines of the project. A provider who keeps to schedule will be an asset.

ADDITIONAL FORMWORK RECOMMENDATIONS

It goes without saying that you need to source the right kind of materials for specific construction requirements. A professional formwork provider knows these requirements.

Although many formworks have certain commonalities that can be used in most construction situations, in modern times, the design specificity and related mechanical requirements are more demanding on the bearing capacity of concrete buildings, and their shapes.  Therefore, you must be careful to choose an informed provider who has the latest equipment at their disposal.
