Productivity in building design and construction
Productivity is the relationship between goods and services produced and the resources used. This concept is critical for the development of any business activity, as those that do not improve their productivity compared to their competitors, are likely to fail.
An increase in production does not necessarily translate into an increase in productivity. To increase productivity, all processes that constitute a company’s activity must be analysed and their efficiency optimised. The resources necessary to increase productivity are:
Capital investment:
- Design of new procedures or improvement of existing ones.
- Installation of more modern machinery or equipment, with a greater capacity or modernisation of existing equipment.
Improved management through a reduction in:
Productivity must not be confused with performance, which is the relationship between forecast and executed work.
Loss in productivity (in terms of time of execution) results from inefficiencies in the total time invested throughout an operation.
The time taken for activities can be broken down into the following:
- Base work content. This is the quantity of work that would be required to manufacture a product or develop an activity if the project were to be perfect, if the procedure, manufacturing or execution method were ideal or if there were no losses in time attributable to any cause. This is the minimum possible time for execution.
- Unnecessary work. This is additional work required due to poor design or specification of the product, or inefficient production or operating methods.
- Ineffective or unproductive time, due to deficiencies in management or deficiencies in workers.

NB Social Value and Design of the Built Environment, published by the Supply Chain Sustainability School in 2017, suggests that: ‘Productivity is about doing (or achieving) more with the same. It can relate to financial returns, and also to outcomes such as learning and health.’
Reinventing Construction: A Route To Higher Productivity, published by the McKinsey Global Institute in February 2017, states: ‘…In its purest form, productivity can be described as the output achieved by a given amount of input.’
