Reducing Wasted Tool-Time

A real-time situational awareness with help of technology solution from Aiforsite

The Threat of Inflation and Unsustainable Construction Costs

Inflation added £23bn to the cost of construction in the UK in 2022. This is not sustainable for the industry and our clients. To survive now and in the future, the industry needs significant and sustainable reductions in construction costs.

The Holy Grail: Reducing Wasted Tool-Time

The reductions in construction costs must be funded by the elimination of the Wasted Tool-Time (WTT). This is the Holy Grail that the industry has consistently failed to grapple with and achieve.

It must become the New Business as Usual Model. Otherwise, will continue to lead to either increasingly severe cost, programme and quality delivery failure or unacceptable and unviable price premiums being paid to attract increasingly finite resources.

The Lean Methodology for Reducing Wasted Tool-time

We at Aiforsite have tools and the Road Map to this Holy Grail of reducing WTT from the current average level of 40% to 10%. We have proved it on a number of projects across the world.

Aiforsite Productivity Platform

Rooted in Lean principles, our methodology follows the model of Continuous Improvement and PDCA cycle.

Technology is used for automatic data collection from the construction site. Multiple data sources create a comprehensive and real-time situational snapshot.

Using the PDCA weekly, we are able to monitor, measure and analyse collected data. Well-documented and stored centrally in one interface, this data reveals the cases of wasted tool-time, helps identify root causes and eliminate them, and supports ensuring task prerequisites for the next work phases.

On a strategic level, the Aiforsite model creates a clear roadmap for measuring, managing and improving performance and productivity continuously. Construction companies can make decisions based on indisputable facts, not guessing.

Thank to well-documented visual information about the construction period, lessons learnt from current projects can and should be utilised in the next projects.

The Importance of Wasted Tool-Time Reduction

We cannot keep on adding costs year by year and expect our clients to keep on paying for it while we do nothing about it. An unacceptable future for Construction Clients, their Stakeholders and Investors that are waking up and realising what they have historically done threatens their businesses and therefore demand change!

Only a 4% WTT Reduction to Beat the Inflation in 2022 in the UK

For every 1% of waste elimination in operatives’ tool-time, the industry gains six minutes a day or half an hour a week. According to the CITB, there were 2.69 million construction workers in the UK at the start of 2022. This equates to 65 million hours annually at £30/hour, which is a potential added value of £2bn (or reduction in costs/year).

The industry only needed a 4% reduction of WTT to counter the inflation cost of labour (£8bn) in 2022, assuming that 35% of construction costs were labour.

Benefits of WTT Reductions

Eliminating WTT not only reduces construction costs but also improves:

  • The well-being of operatives by reducing anxiety, stress, and frustration during work hours.
  • Safety through the reduction of near misses and incidents.

WTT elimination can reduce programmes by up to 50%, Costs by 20%, and CO2 Emissions by 15% whilst increasing customers’ ROI by 20%.

Technology and AI Wendy

In addition to MMC and standardisation (4Ps – Purpose, Process, People, Performance), we need technology and AI. Real-time WTT data processed by AI helps reveal the reasons for waste and apply the appropriate measures collaboratively as a single integrated team.

How does Aiforsite productivity Platform works?

To guide and support project teams on the road map even better, Aiforsite is bringing to Digital Construction Week AI Wendy that will revolutionise the construction industry.

“Wendy” uses deep learning and neural networks, generative AI models, and natural language processing. Wendy will integrate customers’ project information and industry standards into one interface and provide a completely new user experience. Stay tuned and follow us on Linkedin.
