Productivity in Multi-Trade Construction Workflows

Brian Lines, Ibilola Ogundare, Rebecca Kassa, Jake Smithwick, Kenneth Sullivan

This study examined the elapsed-time reduction and equivalent production-rate gain of a reduced-handoff multiskilled workflow compared with a conventional single-trade handoff workflow. The analysis was based on controlled field trials of a common construction scope which requires multiple handoffs between trades, followed by statistical scenario modeling of different handoff conditions.

About This Report

Construction projects often include scopes that require sequential handoffs between multiple trades working in the same work area. Handoffs between trades can create waiting, setup, reorientation, and restart time between productive work activities, which can increase the total elapsed time required to complete the scope. In such cases, field productivity can be directly impacted by how efficiently the work moves from one trade to the next.

In construction scopes which require multiple trades to be closely coordinated in sequence, the study found a reduced-handoff multiskilled workflow achieved an approximate 30% reduction in crew-level elapsed production time relative to a conventional single-trade handoff workflow. In productivity terms, the reduced-handoff workflow with a multiskilled crew completed 43% more installed work during the same production time compared with the conventional single-trade workflow.

Study summary:

What was tested — Crew-level elapsed production time for a multi-trade work sequence
Analysis basis — Controlled field trials with handoff scenario modeling
Observed workflow in controlled trial — 11 activities with 10 trade-to-trade handoffs
Main outcome measure — Modeled elapsed-time reduction (%) and equivalent production-rate gain (%) associated with a reduced-handoff multiskilled workflow

Key Findings

1

For closely sequenced work with frequent handoffs, reducing those handoffs cut completion time by about 30%.

Across all 12 scenarios and 120,000 simulation runs, reducing repeated handoffs shortened the time required for the defined work scope.

2

The reduced-handoff workflow could complete about 43% more installed work in the same amount of production time.

The workers were not assumed to perform individual tasks faster. The result came from reducing waiting, setup, reorientation, coordination, and restart between crews.

3

Multiskilling created the most value when frequent handoffs were concentrated within a closely sequenced work scope.

The size of the benefit ranged from almost none to very large, depending on how frequent and disruptive the handoffs were. Individual modeled scenarios ranged from 2% to 92% less elapsed time.

4

Two multiskilled workers completed a scope spanning seven trade functions without repeatedly handing the work to separate crews.

The one-trade workflow used 12 workers across the same sequence and transferred the work from one trade to another 10 times.
