7 Ways Technology Is Transforming Productivity in Construction
Why the industry can’t afford to stand still
Construction remains one of the largest sectors in the UK economy, but it’s also one of the least productive. According to McKinsey, global construction productivity has increased by only 1% annually over the past twenty years, compared to 2.8% across the entire economy. Closer to home, UK data reveal that 70% of projects still overrun on time or budget.
With labour shortages, rising material costs, and sustainability targets adding further pressure, the industry cannot depend on “business as usual.” Technology and modern methods of construction provide proven ways to build faster, safer, cheaper, and more sustainably.
Here are seven technologies already transforming how projects are designed, built, and delivered – and why they matter.
Quick overview: the 7 technologies making a difference
-
- BIM (Building Information Modelling) – smarter design and collaboration.
- VR & AR – immersive design and real-time site checks.
- Off-site manufacturing – factory-quality builds delivered faster.
- Modular construction – cutting build time by up to 50%.
- Smarter plant & equipment – fewer machines, faster installs.
- 3D printing – additive manufacturing for components and structures.
- Wearable exoskeletons – safer lifting and reduced fatigue.
01. BIM – Building Information Modelling
What it is
Building Information Modelling (BIM) is more than just 3D design software. It creates a shared digital model of a project where architects, engineers, contractors, and clients can collaborate in real-time.
Why it matters
- Clash detection: identify conflicts between services before work starts. HS2’s BIM platform has flagged thousands of issues digitally, saving months of rework.
- Data integration: laser scanning existing sites feeds directly into the design.
- Common data environment: everyone works from one set of drawings, reducing disputes.
What it means for us
For precast retaining walls and storage bays, BIM allows us to model layouts and lifting plans in advance. That means fewer surprises on site and faster, safer installation.
02. VR & AR – bringing drawings to life
What it is
Virtual Reality (VR) and Augmented Reality (AR) turn BIM models into interactive experiences.
Why it matters
- Client buy-in: VR allows clients to “walk through” a building before work begins. This helped Crossrail secure approvals for complex underground stations.
- On-site accuracy: AR overlays BIM models onto live site conditions, indicating if construction aligns with design.
- Training & safety: Immersive VR is now used to train operatives in high-risk tasks without putting them in danger.
What it means for us
For precast retaining walls and storage bays, BIM allows us to model layouts and lifting plans in advance. That means fewer surprises on site and faster, safer installation.
03. Off-site manufacturing
What it is
Manufacturing building components in a controlled factory environment, then delivering them to site for rapid assembly. Precast concrete is one of the oldest and most proven forms.
Why it matters
70% faster than in-situ builds (McKinsey, 2017).
Quality control: factory casting means consistent strength and finish.
Reduced waste: up to 30% less waste compared with on-site construction (Modular Building Institute, 2020).
Labour efficiency: smaller, more productive site teams.
Real-world use
Our precast retaining walls are cast in controlled conditions and then delivered and installed within hours. On one project, a three-person crew installed 100 metres of wall in a single day using vehicle-mounted cranes.
04. Modular construction
What it is
Modular construction involves assembling pre-manufactured units into a complete structure. Think of classrooms, healthcare facilities, or large storage bays – delivered in sections and assembled like building blocks.
Why it matters
50% faster delivery than traditional builds (UK Gov).
Reduced weather delays – foundations can be prepared while elements are being manufactured.
Less waste – components are built to order, not cut on site.
Higher quality: every module is inspected before leaving the factory.
What it means for us
Our retaining walls can be combined with high-tensile fabric shelters (e.g. Toro Shelters) to form modular covered storage bays. The precast provides the structural walls and base, while the fabric roof offers quick, cost-effective protection from the elements.
05. Smarter plant and site equipment
What it is
Modern plant is becoming multi-functional, combining what used to take several machines.
Why it matters
Efficiency: one lorry loader (HIAB) can deliver, offload, and install precast walls without the need for extra cranes.
Reduced labour: smaller teams achieve more.
Safety: Hydraulic grabs and modern lifting systems reduce manual handling.
Read world example
Our installation partner, Modular Cubed, uses vehicle-mounted cranes with hydraulic grabs to offload and position precast wall units directly. With just three people, they routinely install 80–100 metres of wall each day.
06. 3D Printing
What it is
Additive manufacturing builds components or entire structures by layering material – usually a cement-based mix.
Why it matters
- Precision: robots lay material with millimetre accuracy.
- Speed: entire houses have been printed in under 48 hours in the Netherlands.
- Sustainability: reduced waste and the ability to use alternative materials.
Current state
- Used mainly for small-scale modular components and pilot housing projects.
- Ongoing R&D is exploring on-site robotic printing to create walls directly where they’re needed.
How it relates to us
While large-scale 3D printing isn’t yet mainstream, the principles – precision, efficiency, and modular assembly – reflect the benefits of precast construction that we offer today.
07. Wearable exoskeletons
-
- Reduced strain: exosuits can cut muscle load by up to 80%.
- Productivity: workers can perform tasks for longer with less fatigue.
- Safety: fewer injuries mean less downtime and lower insurance costs.
Challenges
The main barrier is cost (£3,000–£5,000 per unit). As prices fall, adoption will likely spread across construction sites.
What can we learn from this?
- Digital design (BIM, VR, AR) helps us plan and collaborate better.
- Off-site and modular methods reduce waste and speed up delivery.
- Smarter equipment and robotics make site work safer and more efficient.
- Wearable tech could help fill labour gaps by extending human performance.
Building faster, safer, smarter with precast
We’ve already seen how combining digital design tools with modular precast systems can shorten project timelines, minimise risk, and free up site resources.
From retaining walls to storage bays, precast offers many of the same benefits as the technologies discussed here: speed, consistency, and flexibility.
If you’d like to discuss how precast can support your next project, our team would be happy to share more ideas.
