Construction Productivity Research Program -- Phase V

A number of CII Best Practices emerged from this research that can result in significant improvements in productivity such as improved cost, schedule, and safety performance. These best productivity practices were safety, materials management, systems integration and automation, team building, front end planning, and constructability. (RS252-1d, p. 23)

Several innovations were found to have impacts on labor productivity of up to 50 percent, with equal or better overall cost impacts than conventional alternatives. These innovations include the following: quick-connect systems for piping, formwork, and structural steel; self-consolidating concrete; and advanced scaffolding and formwork systems. (RS252-1d, p. 23)

In the examination of direct work, it was found that wrench time could be increased on average by about 15 percent with the use of activity analysis processes and tools described in Implementation Resource (IR) 252-2a, Guide to Activity Analysis, and IR252-4d, The Construction Productivity Handbook. Moreover, the team concluded that rework could be reduced by similar amounts through processes described in IR252-2b, A Guide to Construction Rework Reduction. (RS252-1d, p. 24)

Best Productivity Practices Implementation Index (BPPII) is a metric to measure how effectively the methods, tools, and strategies known to improve construction productivity are being implemented on a construction jobsite. Use of the BPPII tools can lead to meaningful productivity improvements because they identify potential construction practice gaps in the planning phase. Filling those gaps may cost time and money, but the payoff can be tremendous. (RS252-1d, p. 25)
