Background
Our client was a construction company undertaking a real estate development backed by a major investment company. Its main development was approximately 2 million square feet in size, and contained over 100 buildings where numerous premier restaurants, high-end shopping outlets and hotels with basements would be located.
The Challenge
The client recognised that there were opportunities to improve productivity of its direct labour workforce, which prompted them to engage Renoir Consulting. The engagement would last a total of 54 weeks and a set number of targets were outlined before implementation.
What We Did
A combined project team of the client’s staff and Renoir consultants was set up to deliver the improvement opportunities. Four technically qualified engineers and a small data management team were seconded full time to the assignment.
Analysis
One of the first activities was to undertake a comprehensive series of Ratio Delay sampling studies and Day in the life of (DILO) studies. These provided data which highlighted under-utilisation of labour force and inadequate supervision during a typical working day.
The observations indicated weaknesses in the disciplines of the workforce on site hour by hour and the extent to which key working times were adhered to. These observations provided better insight into the proportion of productive hours being wasted due to factors such as tower crane unavailability, material unavailability and a lack of effective work planning.
