The Future of Quantity Surveying and Estimating: How Technology is Driving Industry Change

By Coba Pekaj, MAIQS CQS - Director, Pekaj Group

In today’s fast-evolving construction landscape, technology is profoundly transforming the fields of quantity surveying and estimating in Australia. Over the next five years, these industries are expected to experience significant advancements in automation, accuracy, and efficiency, reshaping traditional practices.

Building Information Modelling (BIM):

Building Information Modelling (BIM) has revolutionised quantity surveying services by enabling professionals to create detailed 3D models of construction projects. This innovative technology provides a more accurate and comprehensive understanding of projects compared to traditional 2D drawings. BIM has also streamlined processes for cost management services, allowing for better construction budgeting and resource allocation. According to the Australian Institute of Quantity Surveyors (AIQS), BIM adoption in Australia has increased by 37% over the past two years, demonstrating its growing influence in the industry.

Artificial Intelligence (AI) and Machine Learning (ML):

AI and ML are automating many tasks traditionally associated with construction cost consultants. These technologies can analyse historical data, predict costs with greater accuracy, and optimise resource allocation. AI-powered tools are also increasingly used for estimating and tendering services, enabling faster and more reliable construction financial services. A report by McKinsey & Company in 2023 revealed that AI implementation in the construction sector could reduce project overruns by up to 15% and increase productivity by 20%.

Drones and Remote Sensing Technology:

The use of drones equipped with high-resolution cameras and sensors has streamlined site surveys and data collection for construction projects. Drones provide more accurate data than traditional ground surveys, improving productivity and saving time. This technology has become an essential tool for quantity surveying consultancy and project cost planning, offering real-time insights and better monitoring of site progress. Deloitte’s 2022 report highlighted that drone usage in construction projects has grown by 20%, with companies reporting up to a 40% improvement in site productivity and a 15% reduction in costs.

Virtual Reality (VR) and Augmented Reality (AR):

VR and AR are transforming the way construction projects are visualised. These immersive technologies allow quantity surveyors and building estimators to identify design and constructability issues early in the process, reducing risks and enhancing efficiency. By incorporating VR and AR, construction cost estimating becomes more precise, and teams can better anticipate potential challenges, minimising delays and budget overruns. In a 2023 survey conducted by AIQS, 70% of respondents noted a significant reduction in design changes and Requests for Information (RFIs) after integrating VR and AR into their workflows.

Overcoming Barriers to Adoption:

Despite the clear benefits, some sectors of the construction industry remain hesitant to embrace these innovations due to cost concerns and integration challenges. However, companies that successfully adopt technologies like BIM, AI, drones, and VR/AR are reaping significant rewards, including increased efficiency, reduced costs, and improved safety. Implementing training programs and leveraging government incentives can assist in overcoming these barriers, ensuring a smoother transition to advanced construction project management practices.

What We Actually See in Practice
The reality in the Melbourne market right now is more practical than the headlines suggest. CostX is the platform we use every day and its measurement capabilities have genuinely improved efficiency - we can measure a full residential project in a fraction of the time it took with manual methods ten years ago. BIM integration is useful on larger commercial projects where we receive models, but the majority of residential work in Melbourne still comes to us as 2D PDF drawings. That is unlikely to change for small to medium builders in the next five years.

AI tools are appearing in the market but they are not replacing experienced estimators. They can speed up routine tasks like counting fixtures or measuring repetitive elements, but they cannot assess buildability, identify scope gaps, or apply the kind of judgement that comes from 23 years of pricing Melbourne construction projects.

The biggest technology shift for most builders is not AI -it is moving from spreadsheet-based estimating to a proper measurement platform like CostX or Buildxact. That single change improves accuracy, reduces errors and saves significant time. We provide training on both platforms.

‍Conclusion:

The next five years will bring transformative changes to the quantity surveying and estimating industries in Australia. By embracing cutting-edge technologies such as BIM, AI, drones, and VR/AR, professionals will be well-positioned to deliver enhanced construction budgeting, cost management services, and project planning solutions. Staying ahead of these advancements is not just a choice but a necessity for those aiming to remain competitive in a rapidly evolving industry.
