Cost saving Rework

5 ways Gsite can help cut rework on your project

Rework is one of the biggest issues facing construction companies in the UK. From the biggest Tier 1 to the smallest family firm, rework costs time and money which construction companies cannot afford.

As the cost of rework keeps growing, new solutions are needed. Construction management systems like Gsite are helping businesses cut rework in innovative ways – increasing profits, decreasing waste and solving one of the biggest problems in the sector.

Why is rework a problem for construction companies?

Rework means doing the same job twice, three times or even more. It can be caused by errors on site, poor communication, bad instructions or a lack of oversight. But whatever the cause, the outcome is the same – wasted time, extra expense and lower profit margins.

Small errors across the site add up to programme slips which end up delaying entire projects. The sector needs to work more efficiently than ever before in the modern economy, and the need for rework has grown into a major issue for construction firms.

It can even lead to legal complications in construction. Rework often takes the form of quick fixes which may not be compliant with the specifications, possibly leading to breach of contract and sabotaging Golden Thread responsibilities.

Finally, rework may jeopardise your sustainability commitments. Doing work multiple times means using more materials and generating more waste. Rework does not fit in with the environmentally friendly priorities of the modern construction sector.

What is the cost of rework for UK construction companies?

The Get It Right Initiative estimates the direct cost of avoidable mistakes on site in the UK could be as high as 21% of the total project value[1]. In other words, rework could be causing up to £21bn of waste per year in the UK.

That is a huge number in its own right, but it gets even worse when placed into the overall context that construction firms must face. Data from The Construction Index shows that the average pre-tax profit margin for the top 100 contractors in the UK is just 2.4% in 2025[2].

When looked at from that angle, the value of rework is almost 10 times the average profit margin of the biggest contractors.

At a time when construction firms are finding it harder than ever to make the accounts stack up, minimising rework could be the edge companies need to survive and thrive.

How can Gsite help you minimise rework on site?

One of the most powerful tools available to help minimise rework is the new generation of construction management software solutions. Gsite is a leading example of this and can help cut rework in the following ways:

Planning – Everyone works off the same up-to-date drawings and specifications on a cloud-based dashboard so they know exactly what to do at all times. Potential issues and misunderstandings can be addressed at the start to avoid costly rework in the future.
Easy communication – Issues and information requests can be raised and answered in real time, cutting out the lag in communication that paper-based systems can create. Photographs of work can be uploaded for remote sign off, and feedback can be given instantly so issues are fixed before they become a problem.
Quality control – Inspection checklists can be created and distributed in Gsite so you are always on top of quality control on site. Site diaries are equally easy to create and can be used as key quality control documents.
Accountability – Gsite lets you see the exact make up of every element of your building, who installed it and evidence that they did so correctly. This is vital for reducing rework and also meeting your Golden Thread responsibilities.
Post-work review – Gsite makes it easy to review processes, identify problems and implement solutions once work has finished. That means you can streamline your operations and eliminate issues which caused rework on our last job so that they don’t happen again in future.

Rework is a major problem that can lead to lost profits, delays and more. However, it is not unsolvable. Systems like Gsite provide the tools and processes that you need to limit rework on your next project and limit its negative impact.
