How to reduce the costs of formwork in construction

How to reduce the costs of formwork in construction

Construction projects can be costly processes, so contractors need to find ways to minimise these expenses without affecting the quality of their work. One simple way to minimise the expense of a building is to reduce the costs of concrete formwork. Sometimes formwork can account for up to 60% of the total budget for a building.

New materials, proper planning and prefabricated formwork components can allow contractors to reduce their building expenses without affecting the quality of their work. There are several other ways to reduce the price of formwork, such as using one system throughout the project, using standard form sizes and using the same level for all beams and joints.

Tips for minimising the costs of formwork

  • Use a single framing system for the whole project. This not only helps contractors to learn the formwork system easily, but it also helps to minimise the costs of the formwork set-up.
  • Use the same depth of formwork for all concrete beams. This will help to standardise beam size and shape, making the project quicker and easier.
  • Stick with the same formwork moulds for beams, even if the spans and loads of these beams are different. Contractors can modify the concrete ratios to compensate for various loads on beams.
  • Simplifying the formwork can also help to create uniform shapes and sizes for concrete pillars and beams. 
  • Reuse formwork as much as possible.
  • Use a constant floor-to-floor height between the different levels of a building. This will ensure standardised pillar heights and formwork moulds.
  • Orientate all framing in one direction to save money and time when pouring concrete into the formwork.
  • Consider flat plate formwork for concrete spans up to 7.5 metres as this framing system is the cheapest and fastest to construct.
  • Determine a standard time for the stripping of formwork from poured concrete. This will allow a project to run smoothly and on schedule.

These tips are based on a few general principles. Standardisation and time-management are two of the biggest factors that can reduce the costs of formwork. Contractors need to use standard formwork frames and create concrete beams and pillars of uniforms sizes. This helps to speed up the construction process and in this industry, time is money.

Synthetic fibres can increase the durability of concrete

Contractors sometimes add synthetic fibres to their concrete mix. These fibres of man-made polymers are specifically engineered to withstand the long-term alkaline environment within a concrete mix. They are used to minimise cracking, lower the permeability of the concrete and increase the strength of the structure. They act as a secondary reinforcement element; the primary …

The eight types of construction company

There are many different types of construction company. Not all contractors specialise in the same fields and not all companies do the same construction work. Depending on the type of work they do, construction companies can be classified into the following eight types: 1. General contractors A general contractor provides all of the labour, equipment, …

How to fix common concrete slab problems

When working with concrete, contractors may encounter a few different problems. The following issues can sometimes occur when pouring concrete slabs. While some aspects of working with concrete slabs have changed over the years, many issues have not. Here are three common problems that come with pouring concrete slabs, and their possible solutions. 1) Excessive …

How to prevent dampness in a building

Dampness in a building may occur due to faulty construction, the use of poor-quality building materials or bad architectural design. Dampness affects the lifespan of a building or structure, but it also creates unhygienic conditions. Mold and fungi love to grow in damp conditions, so it is best to fix any signs of wet concrete …

The importance of having a schedule for a construction project

Construction projects are delicate operations that need to run on time in order to stay within the allocated budget. As soon as a project is delayed, it costs the contractors and building owners more money. Having a strict schedule is important as it keeps the project on time and allows all workers to know when …

How to prepare a concrete surface for a topping

Sometimes concrete surfaces are given a decorative topping that adds further protection and durability to a floor or carpark. The underlying concrete will need to be prepared properly before any topping is laid on top. This will ensure that a good bond is formed between the two materials and that no cracks or chips will …
