Mace Case Study: Revolutionizing Commercial Construction with VisiLean

Mace, as the principal contractor, undertook the construction of two significant skyscrapers at 40 Leadenhall Street in central London. These structures span 910,000 square feet and comprise 16 and 38 storeys. The project adhered to stringent carbon footprint requirements, leading Mace to heavily utilise offsite construction for prefabrication of MEP (Mechanical, Electrical, and Plumbing) elements.

• Siloed tools with disconnected planning, execution, and monitoring
• Manual processes consumed 14-16 hours weekly for schedule collation
• Lack of transparency in performance reviews and constraint resolution
• Miscommunication due to disjointed data sharing across teams

VisiLean was introduced mid-project to centralise planning, execution, and monitoring.

Onboarding & Integration — Smooth onboarding through hands-on training, CSV imports, and continuous support enabled rapid adoption across the project team.

Short-Term Planning — Streamlined short-term planning using 2-4-8 week lookaheads with integrated constraint management to keep work on track.

LiveSite App — Empowered on-site teams to update task statuses in real-time, which automatically fed into live dashboards for improved transparency.

Dashboards & Reporting — Automated dashboards and PPC metrics replaced manual reporting, providing 100% real-time visibility into project performance.

• 10+ hours saved weekly: Planner workload reduced from 16 to 4 hours per week
• 100% real-time visibility via automated dashboards and PPC metrics
• Zero manual errors with unified task updates and streamlined data flow
• Enhanced trade engagement through early issue resolution and short-term goal clarity

• Mid-project deployment of digital lean tools is feasible with proper onboarding and training support
• Replacing manual collation processes with automated dashboards delivers immediate time savings
• Real-time task updates from site teams via mobile apps dramatically improve data accuracy
• Transparent performance metrics foster greater trade engagement and accountability
