Construction Productivity Taskforce – 1 Broadgate - Pilot Case Study

This case study, part of Phase 2 of the Construction Productivity Taskforce’s (CPT) Pilot Sites workstream, focuses on slipform operations (two reinforced concrete cores) and cladding operations (installation of circa 2,696 unitised façade panels).

Data collection adhered to the CPT Measurement Framework, as outlined in Measuring Construction Site Productivity: A Seven-Step Framework for Success (2022), leveraging digital technologies to ensure accuracy and granularity.

These included Excel-based trackers for progress records, progress analysis via Disperse technologies, time-lapse photographic records via Site-Eye technology, BIM models, and programme documentation amongst other. Productivity metrics analysed included rates of installation, production cycle times, labour productivity (units/worker-hour) following the Cambridge Performance and Productivity Framework outlined in Measuring Construction Productivity across Projects: Multilevel Three-Dimensional Framework (2024). These methods supported detailed analysis of disrupters and variability, drawing on insights from pilot projects like Landsec’s The Forge and British Land’s Norton Folgate to provide actionable strategies for industry-wide productivity gains.
